This retrospective cohort study evaluates the concordance between Soong grades classified from radiographs and computed tomography (CT) scans and whether a Soong grade ≥1 is associated with flexor pollicis longus (FPL) injury and reoperation incidence. We included 181 patients with 185 dorsally displaced distal radial fractures treated with anterior locking plates. For the analysis of binary Soong grades, grade 0 was compared with grades 1 and 2. A moderate correlation was found between Soong grades on radiographs and CT scans (MCC 0.66). FPL injury occurred in 3% (6/185) and reoperation in 15% (28/185) of cases. There was no statistically significant difference between Soong grades when correlated with the incidence of FPL injury or reoperation, but no patients with a Soong grade 0 had an FPL injury. Binary Soong grading is non-inferior in predictive value and has a better correlation between radiographs and CT scans. Using the Soong classification as a binary system may be easier than a ternary system in clinical practice.

Purpose: This study aimed to evaluate the incidence of, and factors associated with, reoperation after distal radius nonunion repair., Methods: We conducted a retrospective cohort study at a multicenter academic institution and identified adult patients who underwent open reduction and internal fixation for distal radius nonunion between January 2005 and August 2021. Thirty-three patients were included in this study. The cohort consisted of 13 males (13/33) and had a median age of 56 years (interquartile ranges: 49-64). Median follow-up was 59 months (interquartile ranges: 23-126)., Results: Unplanned reoperations occurred in eight of 33 patients. The most common reasons for reoperation were irrigation and debridement for infection, revision surgery for persistent nonunion, and unplanned hardware removal. In total, 10 complications occurred in nine patients. The most common complications were infection and persistent nonunion; both occurred in three cases., Conclusions: Complications after distal radius nonunion repair are common. Reoperation after distal radius nonunion repair is required in approximately one of four cases., Type of Study/level of Evidence: Prognosis IV., Competing Interests: Conflicts of Interest No benefits in any form have been received or will be received related directly to this article., (Copyright © 2024 American Society for Surgery of the Hand.

Anterior interosseous nerve (AIN) syndrome is a rare condition characterized by isolated weakness in the flexor pollicis longus (FPL) muscle, sometimes accompanied by weakness in the index flexor digitorum profundus (FDP) muscle. In this clinical case report, an 18-year-old male presented with a right proximal both-bone forearm fracture that was sustained while playing soccer, with subsequent development of AIN palsy, without sensory deficits or progressive pain. Preoperative imaging was performed, showing a proximal third radius and mid-shaft ulna fracture. Given the progressive presentation of an acute AIN palsy, the patient was indicated for urgent operative intervention. During exploration and decompression of the AIN within the pronator tunnel, the nerve was found to be in continuity but was compressed by a large hematoma and the distal radial shaft. The patient recovered full median nerve function by his six-week postoperative examination and by his final follow-up recovered full range of motion with painless return to full activities. In proximal or mid-shaft both-bone forearm fractures, a careful neurovascular exam is essential, as uncommon conditions like anterior interosseous syndrome (AIS) can present without obvious sensory deficits or pain. Potential etiology for traumatic AIN compression includes significant fracture displacement, soft tissue injury, active extravasation on advanced imaging, and/or clinical concern for compressive hematoma. Patients presenting with FPL and/or index FDP weakness in the absence of sensory deficits or pain on passive stretch may benefit from dedicated surgical exploration and decompression of the AIN to prevent irreversible nerve damage., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: The lay public is increasingly using ChatGPT (a large language model) as a source of medical information. Traditional search engines such as Google provide several distinct responses to each search query and indicate the source for each response, but ChatGPT provides responses in paragraph form in prose without providing the sources used, which makes it difficult or impossible to ascertain whether those sources are reliable. One practical method to infer the sources used by ChatGPT is text network analysis. By understanding how ChatGPT uses source information in relation to traditional search engines, physicians and physician organizations can better counsel patients on the use of this new tool., Questions/purposes: (1) In terms of key content words, how similar are ChatGPT and Google Search responses for queries related to topics in orthopaedic surgery? (2) Does the source distribution (academic, governmental, commercial, or form of a scientific manuscript) differ for Google Search responses based on the topic's level of medical consensus, and how is this reflected in the text similarity between ChatGPT and Google Search responses? (3) Do these results vary between different versions of ChatGPT?, Methods: We evaluated three search queries relating to orthopaedic conditions: "What is the cause of carpal tunnel syndrome?," "What is the cause of tennis elbow?," and "Platelet-rich plasma for thumb arthritis?" These were selected because of their relatively high, medium, and low consensus in the medical evidence, respectively. Each question was posed to ChatGPT version 3.5 and version 4.0 20 times for a total of 120 responses. Text network analysis using term frequency-inverse document frequency (TF-IDF) was used to compare text similarity between responses from ChatGPT and Google Search. In the field of information retrieval, TF-IDF is a weighted statistical measure of the importance of a key word to a document in a collection of documents. Higher TF-IDF scores indicate greater similarity between two sources. TF-IDF scores are most often used to compare and rank the text similarity of documents. Using this type of text network analysis, text similarity between ChatGPT and Google Search can be determined by calculating and summing the TF-IDF for all keywords in a ChatGPT response and comparing it with each Google search result to assess their text similarity to each other. In this way, text similarity can be used to infer relative content similarity. To answer our first question, we characterized the text similarity between ChatGPT and Google Search responses by finding the TF-IDF scores of the ChatGPT response and each of the 20 Google Search results for each question. Using these scores, we could compare the similarity of each ChatGPT response to the Google Search results. To provide a reference point for interpreting TF-IDF values, we generated randomized text samples with the same term distribution as the Google Search results. By comparing ChatGPT TF-IDF to the random text sample, we could assess whether TF-IDF values were statistically significant from TF-IDF values obtained by random chance, and it allowed us to test whether text similarity was an appropriate quantitative statistical measure of relative content similarity. To answer our second question, we classified the Google Search results to better understand sourcing. Google Search provides 20 or more distinct sources of information, but ChatGPT gives only a single prose paragraph in response to each query. So, to answer this question, we used TF-IDF to ascertain whether the ChatGPT response was principally driven by one of four source categories: academic, government, commercial, or material that took the form of a scientific manuscript but was not peer-reviewed or indexed on a government site (such as PubMed). We then compared the TF-IDF similarity between ChatGPT responses and the source category. To answer our third research question, we repeated both analyses and compared the results when using ChatGPT 3.5 versus ChatGPT 4.0., Results: The ChatGPT response was dominated by the top Google Search result. For example, for carpal tunnel syndrome, the top result was an academic website with a mean TF-IDF of 7.2. A similar result was observed for the other search topics. To provide a reference point for interpreting TF-IDF values, a randomly generated sample of text compared with Google Search would have a mean TF-IDF of 2.7 ± 1.9, controlling for text length and keyword distribution. The observed TF-IDF distribution was higher for ChatGPT responses than for random text samples, supporting the claim that keyword text similarity is a measure of relative content similarity. When comparing source distribution, the ChatGPT response was most similar to the most common source category from Google Search. For the subject where there was strong consensus (carpal tunnel syndrome), the ChatGPT response was most similar to high-quality academic sources rather than lower-quality commercial sources (TF-IDF 8.6 versus 2.2). For topics with low consensus, the ChatGPT response paralleled lower-quality commercial websites compared with higher-quality academic websites (TF-IDF 14.6 versus 0.2). ChatGPT 4.0 had higher text similarity to Google Search results than ChatGPT 3.5 (mean increase in TF-IDF similarity of 0.80 to 0.91; p < 0.001). The ChatGPT 4.0 response was still dominated by the top Google Search result and reflected the most common search category for all search topics., Conclusion: ChatGPT responses are similar to individual Google Search results for queries related to orthopaedic surgery, but the distribution of source information can vary substantially based on the relative level of consensus on a topic. For example, for carpal tunnel syndrome, where there is widely accepted medical consensus, ChatGPT responses had higher similarity to academic sources and therefore used those sources more. When fewer academic or government sources are available, especially in our search related to platelet-rich plasma, ChatGPT appears to have relied more heavily on a small number of nonacademic sources. These findings persisted even as ChatGPT was updated from version 3.5 to version 4.0., Clinical Relevance: Physicians should be aware that ChatGPT and Google likely use the same sources for a specific question. The main difference is that ChatGPT can draw upon multiple sources to create one aggregate response, while Google maintains its distinctness by providing multiple results. For topics with a low consensus and therefore a low number of quality sources, there is a much higher chance that ChatGPT will use less-reliable sources, in which case physicians should take the time to educate patients on the topic or provide resources that give more reliable information. Physician organizations should make it clear when the evidence is limited so that ChatGPT can reflect the lack of quality information or evidence., Competing Interests: Each author certifies that there are no funding or commercial associations (consultancies, stock ownership, equity interest, patent/licensing arrangements, etc.) that might pose a conflict of interest in connection with the submitted article related to the author or any immediate family members.

Purpose: Symptomatic trapeziometacarpal (TMC) joint arthritis is a common cause of hand pain. It is unknown how many patients ultimately elect to have bilateral surgery for TMC arthritis. In this study, we assessed the frequency and predictive factors for contralateral TMC surgery in patients who underwent prior TMC surgery., Methods: We identified 712 patients who underwent primary surgery for TMC arthritis with a follow-up period of 5 years. We collected demographic, surgical, and follow-up data. Prediction models for contralateral surgery using a training and testing data set were created with multivariable logistic regression and random forest classifier algorithms., Results: At the time of initial surgery, 230 patients had bilateral thumb pain (32%), but only 153 patients ultimately had an operation for TMC arthritis on the contralateral side within 5 years (21% of 712 total patients and 67% of 230 patients with bilateral pain). Common predictive factors between both models for contralateral surgery were younger age (odds ratio [OR] = 0.95; 95% confidence interval [CI], 0.93-0.98), bilateral thumb pain (OR = 3.76; 95% CI, 2.52-5.65), and anxiety disorders (OR = 1.84; 95% CI, 1.11-3.03)., Conclusions: In our study, we found that the rate of contralateral surgery was 21% in patients who underwent prior TMC surgery. Predictive factors for future contralateral surgery included younger age, bilateral thumb pain, and anxiety disorder at the time of initial surgery., Type of Study/level of Evidence: Prognostic II., (Copyright © 2024 American Society for Surgery of the Hand.

Background: We assessed factors associated with change in radiographic teardrop angle following volar locking plate (VLP) fixation of volarly displaced intra-articular distal radius fractures with volar ulnar fragments (VUF) within the ICUC database. The primary outcome was change in radiographic alignment on follow-up imaging, defined as a change in teardrop angle from intra-operative fluoroscopy greater than 5°., Methods: Patients with distal radius fractures treated with a VLP within the ICUC database, an international collaborative and publicly available dataset, were identified. The primary outcome was volar rim loss of reduction on follow-up imaging, defined as a change in radiographic alignment from intra-operative fluoroscopy, teardrop angle less than 50°, or loss of normal radiocarpal alignment. Secondary outcomes were final range of motion (ROM) of the affected extremity. Radiographic Soong classification was used to grade plate position. Descriptive statistics were used to assess variables' distributions. A Random Forest supervised machine learning algorithm was used to classify variable importance for predicting the primary outcome. Traditional descriptive statistics were used to compare patient, fracture, and treatment characteristics with volar rim loss of reduction. Volar rim loss of reduction and final ROM in degrees and as compared with contralateral unaffected limb were also assessed., Results: Fifty patients with volarly displaced, intra-articular distal radius fractures treated with a VLP were identified. Six patients were observed to have a volar rim loss of reduction, but none required reoperation. Volar ulnar fragment size, Soong grade 0, and postfixation axial plate position in relation to the sigmoid notch were significantly associated ( P < .05) with volar rim loss of reduction. All cases of volar rim loss of reduction occurred when VUF was 10.8 mm or less., Conclusions: The size of the VUF was the most important variable for predicting volar rim loss of reduction followed by postfixation plate position in an axial position to the sigmoid notch and the number of volar fragments in the Random Forest machine learning algorithm. There were no significant differences in ROM between patients with volar ulnar escape and those without., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: REC, YAJH, CLEL, AG, PR, and JCM have nothing to disclose.

Background: This research sought to analyze a cohort of patients with extensor pollicis longus (EPL) ruptures after volar locked plating of a distal radius fracture (DRF) to characterize the incidence of ruptures that are unlikely to be related to dorsal screw prominence., Methods: This is a retrospective, observational, descriptive cohort study of adults with operative fixation of a closed DRF and an EPL rupture between 2002 and 2022. Eighteen patients with operative fixation using a volar plate of a closed DRF had an EPL rupture. The cohort consisted of 66% women with an average age of 57.5 years. Median follow-up was 14.5 months., Results: The incidence of EPL rupture was 0.4% (18/4768). The average time from DRF and DRF fixation to EPL rupture was 3.7 and 3.4 months, respectively. Based on the operative record, in 2 of the 18 patients (11%), the rupture was directly attributable to prominent hardware; however, in 4 of the 18 patients (22%), the rupture was not related to prominent hardware, and the cause was indeterminate in 12 patients (67%). Radiologic analysis of those in the indeterminate group demonstrated that 5 of the 12 patients had screws that had a high probability of being prominent., Conclusions: The incidence of EPL rupture after volar plating of DRF is between 0% and 1% and usually occurs about 3 months after fixation. Approximately 50% of EPL ruptures are attributable to prominent dorsal screws. Although screw prominence is an important cause of EPL rupture, it is not the sole cause of rupture., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Idiopathic inflammatory myopathies (IIM) are marked by progressive muscle weakness and lasting disability. Therapies targeting patient well-being include the use of prescription drugs as well as exercise. Maintaining or increasing muscular strength and endurance as well as cardiorespiratory fitness (CRF) improves quality of life (QoL) as well as functional status in IIM patients. This narrative review highlights exercise interventions in patients of different IIM subtypes with the intent to provide a summary table with exercise recommendations that will safely and effectively improve QoL in myositis patients.

Background: The Soong classification grades the prominence of volar locking plates used to treat distal radius fractures in relation to the volar rim. The basis of the classification scheme is that increasing plate prominence over the volar rim and distal radius watershed zone is associated with increased likelihood of flexor tendon irritation and need for plate removal. However, recent studies report mixed results on the predictive value of the Soong classification for these outcomes. We hypothesized that the decreased predictive accuracy of Soong classification is due to misclassification between Soong grades secondary to a suboptimal correlation between the Soong classification on radiographs (XRs) and computed tomography (CT)., Methods: Fifty volarly displaced distal radius fractures treated with a volar locking plate in the international and publicly available ICUC database were reviewed. All cases with a postoperative XR and CT were included. Soong classification of the volar locking plate in relation to the volar ulnar rim was determined on both XR and CT by 2 independent, fellowship-trained hand surgeons using CT imaging as the gold standard. The distribution of Soong grades on XR and CT was compared using Pearson's χ 2 test, and correlation was calculated using the Matthews correlation coefficient (MCC). A multi-class confusion matrix was used to calculate each grade's positive predictive value (PPV)., Results: We found an MCC of 0.65, indicating only moderate correlation between the 2 modalities. Per individual Soong grade, the PPV was the highest for grade 2 (0.96), with lower PPVs for grade 0 (0.63) and grade 1 (0.60)., Conclusions: The distribution of Soong grades was significantly different when using XR versus CT ( P < .001)., Level of Evidence: Oxford Centre for Evidence-Based Medicine, diagnostic, level 2b., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: R.E.C., Y.A.J.H., R.G., and J.C.M. have nothing to disclose.

The economic burden of idiopathic inflammatory myopathies (IIMs) within the US is underexplored. We hypothesized that IIMs patients experience considerable personal financial burden due to risks of multi-specialist visits, chronic long-term care, costs associated with disability, medical treatment, and overall high spending costs within the US healthcare system. We surveyed members of Myositis Support and Understanding (MSU) (response rate 4.7 %), and of the 470 survey participants that self-reported with diagnoses of IIMs, we assessed financial burden using two validated measures: (1) Financial Worry Score, and (2) Financial Burden Composite Score (FBCS). We determined factors associated with increased FBCS using logistic and Poisson regression respectively. High financial worry was endorsed by 202 participants (43 %) and the average FBCS ± SD was 1.8 ± 1.9. The odds of financial worry among participants with Medicaid is 3.016 times the odds of financial worry among participants without Medicaid (p = 0.011), and the odds of financial worry among participants with private high-deductible insurance is 3.216 times the odds of financial worry among participants who do not have private high-deductible insurance (p =< 0.001). Given the link between personal financial burden and potential effects on patient outcomes, it is essential for physicians to consider patient financial health when determining management or treatment courses. Identifying specific risk factors that can further exacerbate personal financial burden can help physicians identify vulnerable patients to reduce financial hardship., Competing Interests: Declaration of Competing Interest All authors have no financial disclosures or relevant conflicts of interest to report., (Copyright © 2023 Elsevier B.V.

Background: Sporadic inclusion body myositis (sIBM) is a rare and slowly progressive skeletal muscle disease that can cause hand dysfunction, which is a major source of disability. Tendon transfers have been reliably used to improve function in other neuromuscular settings. Given that sIBM patients often present with flexion impairments and mostly functioning extensors, we investigated the potential opportunity for tendon transfer surgery to improve hand dysfunction in sIBM patients., Methods: We conducted a scoping review for studies of sIBM and tendon transfers, extracted descriptions of hand function and surgical technique, and recorded results in terms of hand function. We also conducted an institutional review board-approved survey with 470 participants to determine baseline patient-reported function and to determine participant perceptions and expectations for tendon transfer surgery to improve hand function in sIBM., Results: We identified three published case reports on tendon transfers in sIBM patients with subjectively improved grip and pinch strength, but standardized measures of hand function or quality-of-life were not reported. Within the surveyed cohort, half of participants reported that they would consider surgery, yet only 8% had been referred to a hand surgeon. Fifty four percent of participants reported that they would consider surgery if there would be 1-2 years of benefit after surgery. All participants who would consider surgery also had significant upper extremity disability., Discussion: Tendon transfer surgery has the potential to improve quality-of-life for sIBM patients, and there is significant patient interest in this approach. To objectively assess its efficacy, we propose conducting a surgical trial., Competing Interests: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2023 The Authors.

Background: The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) is a validated, static hand and upper extremity patient-reported outcome measure (PROM) commonly used. However, with the growth of PROM implementation across orthopedic and plastic surgery clinics, it is beneficial to determine whether a more general PROM can be used to capture the same insights. This would ease implementation broadly. There is a paucity of literature assessing whether the QuickDASH and Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 are correlated and perform similarly., Methods: Between June 2016 and December 2020, hand and upper extremity patients seeking care at clinics associated with a single quaternary academic medical center were identified. Those who completed the PROMIS Global-10 and QuickDASH as part of routine care were identified. The PROMIS Global-10 is divided into the PROMIS Global Physical Health and PROMIS Global Mental Health subscores. Spearman rho (ρ) correlations were calculated across PROMs, and ceiling and floor effects were determined., Results: Across the 18 744 included patients, there was a strong correlation and strong-moderate correlation found between the QuickDASH and PROMIS Global Physical Health (ρ = 0.70, P < .001) and PROMIS Global Mental Health (ρ = 0.69, P < .001), respectively. Although small, QuickDASH demonstrates the worst floor effect (2.6%, [n = 478]), whereas PROMIS Global Mental Health demonstrated a much more notable ceiling effect (11%, [n = 2034])., Conclusions: The PROMIS Global-10 can be used to assess the functional status of patients presenting for hand and upper extremity concerns, while also capturing aspects of mental health. The PROMIS Global-10 may ease PROM implementation broadly., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: D.N.B. received research grant funding from the American Orthopaedic Foot & Ankle Society, American Foundation for Surgery of the Hand (unrelated to this study), and Cervical Spine Research Society and personal fees from the Institute for Strategy and Competitiveness at Harvard Business School, COSF/Boston Children’s Hospital, Mass General Brigham, CAPADEV, The Heritage Foundation, National Academy of Medicine (NAM), and Spine (Social Media Editor), outside of the submitted work.

Background: Multiple techniques have been described to treat humeral diaphyseal bone tumors requiring curettage or excision. Recent studies have suggested that carbon fiber-reinforced polyetheretherketone (CFR-PEEK) intramedullary nails (IMNs) may be preferable to titanium IMNs for patients with musculoskeletal tumors due to CFR-PEEK's high tensile strength, radiolucency, a modulus of elasticity closer to native bone, and improved postoperative surveillance/radiation dosing. In this study, we describe the rate of fixation failure for both CFR-PEEK and titanium humeral IMNs when used for humeral diaphyseal bone tumors requiring curettage or excision., Methods: This was a single-institution retrospective cohort study including 81 patients (27 CFR-PEEK and 54 titanium) treated for a humeral diaphyseal bone tumor using an IMN ± methylmethacrylate between January 2017 and December 2022. Primary outcome was revision surgery due to soft tissue complications, nonunions, structural complications such as periprosthetic fracture or IMN breakage, periprosthetic infection, tumor progression, and implant failure due to rejection or fatigue., Results: No failures were observed in either patients treated with titanium nails or patients treated with CFR-PEEK not requiring curettage. Fixation failure due to implant failure was observed in 2 cases-at 214 days and 469 days after surgery-where CFR-PEEK IMN was used for stabilization after a wide segmental resection for oncologic control with a cement spacer reconstruction. In both cases, the resection was larger than 6 cm, the remaining distal humerus was less than 5 cm, and failures occurred at the interface of the residual bone and spacer. Both patients were revised using a titanium distal posterolateral humeral plate fixed with screws and cables without any subsequent complications. One additional CFR-PEEK IMN required revision surgery after 744 days due to progression of the tumor and subsequent nonunion. One revision surgery was observed after 63 days for the titanium IMN because of nonunion and tumor progression., Conclusions: Humeral diaphyseal bone tumors requiring large segmental resection with small residual bone and a large cement spacer may fail via tension due to bending forces at the distal portion. In this clinical scenario, the use of larger-diameter CFR-PEEK IMNs may be indicated when available. In the interim, use of intercalary allografts instead of cement spacers, additional fixation with a titanium plate distally, or the use of a titanium nail when using a cement spacer may be considered., (Copyright © 2023 Journal of Shoulder and Elbow Surgery Board of Trustees.

Arthroscopic-assisted fracture fixation can be used for some adult elbow fractures. In particular, for articular fractures of the anterior elbow (coronoid/capitellum), elbow arthroscopy can provide excellent visualization of fracture fragments using a less invasive surgical exposure. Meticulous adherence to safe techniques and utilization of specialized equipment can help maximize safety and facilitate reproducible surgical results., (Copyright © 2023 Elsevier Inc.

Abstract: ➢ Natural language processing with large language models is a subdivision of artificial intelligence (AI) that extracts meaning from text with use of linguistic rules, statistics, and machine learning to generate appropriate text responses. Its utilization in medicine and in the field of orthopaedic surgery is rapidly growing.➢ Large language models can be utilized in generating scientific manuscript texts of a publishable quality; however, they suffer from AI hallucinations, in which untruths or half-truths are stated with misleading confidence. Their use raises considerable concerns regarding the potential for research misconduct and for hallucinations to insert misinformation into the clinical literature.➢ Current editorial processes are insufficient for identifying the involvement of large language models in manuscripts. Academic publishing must adapt to encourage safe use of these tools by establishing clear guidelines for their use, which should be adopted across the orthopaedic literature, and by implementing additional steps in the editorial screening process to identify the use of these tools in submitted manuscripts., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article ( http://links.lww.com/JBJS/H601 )., (Copyright © 2023 by The Journal of Bone and Joint Surgery, Incorporated.)

Objective: To investigate the effects of discharge opioid supply after surgery for musculoskeletal injury on subsequent opioid use., Study Design: Instrumental variables analysis of retrospective administrative data., Methods: Data were acquired on 1039 patients treated operatively for a musculoskeletal injury between 2011 and 2015 at 2 level I trauma centers. State registry data were used to track all postoperative opioid prescription fills. Discharge surgical resident was identified for each patient. We categorized residents in the top one-third of opioid prescribing as high-supply residents and others as low-supply residents, with adjustment for service attending physician and month. The primary outcome was subsequent opioid use, defined as new opioid prescriptions and cumulative prescribed opioid supply 7 to 8 months after injury., Results: On average, patients of high-supply residents received an additional 96 morphine milligram equivalents (MME) at discharge (95% CI, 29-163 MME; P < .01), or 16% more, compared with patients of low-supply residents, which is equivalent to an additional 2-day supply at a typical dosage. In the seventh or eighth month after surgery, patients of high-supply residents received a greater total MME volume than patients of low-supply residents (difference, 13.0 MME; 95% CI, 3.1-22.9 MME; P < .01) despite receiving a greater cumulative supply of opioid medications through the sixth month after surgery., Conclusions: After surgery for musculoskeletal injury, patients discharged by residents who prescribe greater supplies of opioid pain medications received higher supplies of opioids 7 to 8 months after surgery than patients discharged by residents who tend to prescribe less. Thus, limiting postoperative supplies of opioid pain medication may help reduce chronic opioid use.

Purpose: Peripheral neuropathies after shoulder arthroscopy are rare, though likely under-reported. Many resolve spontaneously, but some patients are left with permanent neurological deficits. The purpose of this study was to review the literature to better characterize this patient population, diagnostic tests performed, the timing and type of surgical intervention, and report clinical outcomes., Methods: A systematic literature review was performed. Articles in English were identified from PubMed, EMBASE, and CINAHL in August 2021. Article titles and abstracts were screened for relevance by two authors and discordant abstracts were resolved by the senior author. Data were subsequently extracted from the included articles., Results: Seventeen articles were identified yielding a total of 91 patients. The average age was 53 ± 12 years, and most patients were male (72%). Rotator cuff repair (62%) was the most common procedure performed. A peripheral neuropathy was identified an average of 80 ± 81 days from the index procedure (range, 0-240 days). Most commonly, peripheral nerve injury presented as a mononeuropathy, with the median nerve (39%) and ulnar nerve (17%) affected predominantly. Seventeen percent of patients underwent a secondary surgery at an average of 232 ± 157 days after the index procedure. At the final follow-up, 55% of neuropathies had resolved, 14% partially improved, and 22% showed no clinical improvement. The most proposed etiologies were postoperative immobilization (29%) and intraoperative positioning (20%), but several possible etiologies have been suggested., Conclusions: Peripheral neuropathies after arthroscopic shoulder procedures are rare. While most spontaneously resolve, up to 1 in 5 patients may have persistent neuropathic symptoms. A high index of suspicion should be maintained throughout the postoperative period. When neurologic deficits are identified, patients should undergo a thorough diagnostic workup and be referred to a subspecialist in a timely manner., (© 2023 The Authors.)

Scaphoid and carpal bone fractures are challenging injuries to manage and have significant functional implications. Prompt diagnosis is important and relies on systematic evaluation via history, examination, and imaging. Cross-sectional imaging is often helpful for diagnosis and treatment planning. Treatment for nondisplaced fractures is often closed but these injuries typically require prolonged immobilization and may still result in nonunion or avascular necrosis.

Cigarette smoke-exposed (CS-exposed) Cc16-/- mice have exaggerated COPD-like disease associated with increased NF-κB activation in their lungs. It is unclear whether CC16 augmentation can reverse exaggerated COPD in CS-exposed Cc16-/- mice and whether increased NF-κB activation contributes to the exaggerated COPD in CS-exposed Cc16-/- lungs. CS-exposed WT and Cc16-/- mice were treated with recombinant human CC16 (rhCC16) or an NF-κB inhibitor versus vehicle beginning at the midpoint of the exposures. COPD-like disease and NF-κB activation were measured in the lungs. RhCC16 limited the progression of emphysema, small airway fibrosis, and chronic bronchitis-like disease in WT and Cc16-/- mice partly by reducing pulmonary inflammation (reducing myeloid leukocytes and/or increasing regulatory T and/or B cells) and alveolar septal cell apoptosis, reducing NF-κB activation in CS-exposed Cc16-/- lungs, and rescuing the reduced Foxj1 expression in CS-exposed Cc16-/- lungs. IMD0354 treatment reduced exaggerated lung inflammation and rescued the reduced Foxj1 expression in CS-exposed Cc16-/- mice. RhCC16 treatment reduced NF-κB activation in luciferase reporter A549 cells. Thus, rhCC16 treatment limits COPD progression in CS-exposed Cc16-/- mice partly by inhibiting NF-κB activation and represents a potentially novel therapeutic approach for COPD.

Background: Radial head and neck fracture malunion can lead to pain, stiffness, deformity, and functional limitations. This study analyzed the early radiographic and functional outcomes of corrective osteotomy for symptomatic radial head and/or neck malunion in skeletally immature patients., Methods: Thirteen pediatric patients treated with corrective osteotomy for symptomatic radial head and/or neck malunion from 2004 to 2018 were identified. Radiographic union, range of motion, pain, and complications were recorded. Functional outcomes were assessed using the Broberg and Morrey Elbow Scale., Results: The average age at the time of surgery was 12.3 years (range: 8.6 to 16.3). The mean time from injury to osteotomy was 7.5 months (range: 2 to 24.1 mo). Before osteotomy, mean radial head-shaft angulation was 23 degrees (range: 5 to 57 degrees), mean displacement was 76% (range: 0 to 55), average elbow flexion contracture was 18 degrees (range: 0 to 60 degrees), and average elbow flexion was 112 degrees (range: 95 to 135 degrees). After a mean follow-up of 14.3 months, 12 of 13 osteotomies (92%) healed; 1 patient had a painless nonunion. The number of patients reporting pain decreased from 9 to 2 ( P =0.012). Radiographic alignment and range of motion improved in all patients. Mean angulation and displacement improved to 8 degrees (range: 2 to 15 degrees, P =0.001) and 3% (range: 0 to 18 degrees, P =0.001), respectively. Mean elbow flexion contracture was reduced to 5 degrees (range: 0 to 30 degrees, P =0.008), and the average elbow flexion increased to 128 degrees (range: 100 to 135 degrees, P <0.001). Three patients underwent implant removal for complications, including heterotopic ossification and avascular necrosis. Physeal arrest did not lead to any adverse sequelae. The sole case of avascular necrosis had a reduced range of motion but no pain. The mean postoperative Broberg and Morrey score was 91.1; 7 patients had excellent postoperative scores, 4 good, and 2 fair., Conclusions: Corrective osteotomy for symptomatic malunion of the radial head and/or neck in skeletally immature patients can improve elbow alignment, motion, pain, and function. Preservation of the soft-tissue attachments to the proximal epiphysis and rigid internal fixation are critical components of this surgical technique., Level of Evidence: Therapeutic Level IV., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Insurance status is important as medical expenses may decrease the likelihood of follow-up after musculoskeletal trauma, especially for low-income populations. However, it is unknown what insurance factors are associated with follow-up care. In this study, we assessed the association between insurance plan benefits, the end of the post-surgical global period, and follow-up after musculoskeletal injury., Methods: This is a retrospective cohort study of 394 patients with isolated extremity fractures who were treated at three level-I trauma centers over four months in 2018. Paired t-tests were utilized to assess the likelihood of follow-up in relation to the 90-day post-surgical global period. Regression analysis was used to assess factors associated with the likelihood of follow-up. Supervised machine learning algorithms were used to develop predictive models of follow-up after the post-surgical global period., Results: Our final analysis included 328 patients. Likelihood of follow-up did not significantly change while within the post-surgical global period. When comparing follow-up within and outside of the post-surgical global period, there was a 20.1% decrease in follow-up between the 6-weeks and 6-month time points (68.3% versus 48.2%, respectively; p < 0.0001). Medicaid insurance compared to Medicare (OR 0.27, 95% confidence interval (CI) = [0.09, 0.84], p = 0.02) was a predictor of decreased likelihood of follow-up at 6-months post-operatively., Conclusions: Our study demonstrates a statistically significant decrease in follow-up for orthopaedic trauma patients after the post-surgical global period, particularly for patients with Medicaid or Private insurance., (© 2023.

Metacarpal fractures are a common injury in the hand. When surgical intervention is indicated, there are multiple approaches and techniques of fixation. Intramedullary fixation has become an increasingly versatile method of fixation. The limited dissection needed for its insertion, rotational stability provided by the isthmic fit and lack of requisite hardware removal are improvements over conventional K-wire or plate fixation techniques. Multiple outcome studies have confirmed its safety and effectiveness. In this technical note, we provide some tips that can help surgeons considering intramedullary headless screw fixation of metacarpal fractures. Level of Evidence: Level V (Therapeutic).

Carbon fiber offers numerous material benefits including reduced wear, high strength-to-weight ratio, a similar elastic modulus to that of bone, and high biocompatibility. Carbon fiber implants are increasingly used in multiple arenas within orthopaedic surgery, including spine, trauma, arthroplasty, and oncology. In the orthopaedic oncologic population, the radiolucency of carbon fiber facilitates post-operative imaging for tumor surveillance or recurrence, the monitoring of bony healing and union, and radiation mapping and delivery.

Background: Electronic patient portal (EPP) use is associated with lower no-show rates and increased patient satisfaction. However, there are disparities in enrollment into these communication platforms., Objective: We hypothesized that guided inpatient enrollment into an EPP would improve clinical follow-up and EPP use rates for patients who underwent orthopedic surgery compared to the usual practice of providing information in the discharge summary., Methods: We performed a randomized controlled trial of 229 adult patients who were admitted to the hospital for an orthopedic condition that required a 3-month follow-up visit. Patients were cluster-randomized by week to either the control or intervention group. The control group received information on how to enroll into and use the EPP in their discharge paperwork, whereas the intervention group was actively enrolled and taught how to use the EPP. At 3 months postdischarge, the patients were followed to see if they attended their follow-up appointment or used the EPP., Results: Of the 229 patients, 83% (n=190) presented for follow-up at 3 months (control: 93/116, 80.2%; intervention: 97/113, 85.8%; P=.25). The likelihood of EPP use was significantly higher in the intervention group (control: 19/116, 16.4%; intervention: 70/113, 62%; odds ratio [OR] 8.3, 95% CI 4.5-15.5; P<.001). Patients in the intervention group who used the EPP were more likely to present for postsurgical follow-up (OR 3.59, 95% CI 1.28-10.06; P=.02)., Conclusions: The inpatient enrollment of patients who underwent orthopedic surgery into an EPP increased EPP use but did not independently result in enhanced follow-up. Patients who were enrolled as inpatients and subsequently used the portal had the highest likelihood of 3-month follow-up., Trial Registration: ClinicalTrials.gov NCT03431259; https://clinicaltrials.gov/ct2/show/NCT03431259., (©Abhiram R Bhashyam, Mira Bansal, Madeline M McGovern, Quirine M J van der Vliet, Marilyn Heng.

Aims: Due to their radiolucency and favourable mechanical properties, carbon fibre nails may be a preferable alternative to titanium nails for oncology patients. We aim to compare the surgical characteristics and short-term results of patients who underwent intramedullary fixation with either a titanium or carbon fibre nail for pathological long-bone fracture., Methods: This single tertiary-institutional, retrospectively matched case-control study included 72 patients who underwent prophylactic or therapeutic fixation for pathological fracture of the humerus, femur, or tibia with either a titanium (control group, n = 36) or carbon fibre (case group, n = 36) intramedullary nail between 2016 to 2020. Patients were excluded if intramedullary fixation was combined with any other surgical procedure/fixation method. Outcomes included operating time, blood loss, fluoroscopic time, and complications. Fisher's exact test and Mann-Whitney U test were used for categorical and continuous outcomes, respectively., Results: Patients receiving carbon nails as compared to those receiving titanium nails had higher blood loss (median 150 ml (interquartile range (IQR) 100 to 250) vs 100 ml (IQR 50 to 150); p = 0.042) and longer fluoroscopic time (median 150 seconds (IQR 114 to 182) vs 94 seconds (IQR 58 to 124); p = 0.001). Implant complications occurred in seven patients (19%) in the titanium group versus one patient (3%) in the carbon fibre group (p = 0.055). There were no notable differences between groups with regard to operating time, surgical wound infection, or survival., Conclusion: This pilot study demonstrates a non-inferior surgical and short-term clinical profile supporting further consideration of carbon fibre nails for pathological fracture fixation in orthopaedic oncology patients. Given enhanced accommodation of imaging methods important for oncological surveillance and radiation therapy planning, as well as high tolerances to fatigue stress, carbon fibre implants possess important oncological advantages over titanium implants that merit further prospective investigation.

Purpose: Multiple prior studies have assessed the results of open approaches for concurrent carpal tunnel release with distal radius fracture fixation; however, less is known regarding the feasibility of endoscopic techniques, especially in the setting of high-energy trauma. In this study, we assessed the feasibility and results of concurrent endoscopic carpal tunnel release and distal radius fracture fixation using the flexor carpi radialis approach after high- and low-energy trauma., Methods: We performed a retrospective, single-surgeon study of 17 consecutive adult patients (aged >18 years) who underwent open reduction internal fixation of an acute distal radius fracture with concurrent endoscopic carpal tunnel release at a level 1 trauma center between April 2017 and October 2020. Recovery from median nerve dysfunction was assessed from patient charts at routinely scheduled postoperative follow-up visits (at 2 weeks, 4 weeks, 6 weeks, and 12 weeks)., Results: The transverse carpal ligament could be visualized and released in all patients. All patients had a return of light touch sensibility with or without intermittent paresthesia by 12 weeks after surgery (the median time from surgery to recovery was 19 days [range, 12-82 days]). There were no patient reports or clinical examination evidence of palmar cutaneous branch, recurrent motor branch, or the third common digital nerve injury. Time to recovery was significantly different in the setting of high- versus low-energy trauma (26 days vs 18 days, respectively; P  = .02)., Conclusions: In this study, we demonstrated that concurrent endoscopic carpal tunnel release using the flexor carpi radialis approach for distal radius fracture fixation in the settings of high- and low-energy trauma is safe from major complications and effective at releasing the transverse carpal ligament., Type of Study/level of Evidence: Therapeutic IV., (© 2021 The Authors.)

The incidence of geriatric ankle fractures is rising and the potential for complications is high in this population. Little is known about factors associated with increased postoperative complications after surgical fixation of ankle fractures in older-age patients. The purpose of this retrospective cohort study was to assess the epidemiology and risk factors for complications after surgically treated ankle fractures in geriatric patients. All patients who were 65 years or older and had a surgically treated ankle fracture were included. Pilon fractures, patients who were initially treated conservatively or who had less than 1 month of follow-up were excluded. Postoperative complications, demographic-, fracture- and surgical data of 282 patients were recorded from two level 2 trauma centers between 2012 and 2017. A total of 87 (30.9%) patients developed a complication, of which wound related complications were most frequently reported. Superficial and deep wound infections were observed in 27 (9.6%) and 18 (6.4%) patients, respectively. Multivariate regression analysis demonstrated increased age to be an independent predictive variable for the occurrence of postoperative complications (odds ratio 1.04; 95% confidence interval 1.00-1.09), while cast immobilization for more than 2 weeks was a protective factor for the development of wound related complications (odds ratio 0.34; 95% confidence interval 0.17-0.66). In conclusion, the incidence of postoperative complications among geriatric patients after surgical treatment of ankle fractures is high and patients should be informed accordingly., (Copyright © 2021 the American College of Foot and Ankle Surgeons.

Nerve transection injuries can result in painful neuromas that adversely affect patient recovery. This is especially significant following amputation surgeries in the setting of prosthetic wear and function. Targeted Muscle Reinnervation and Regenerative Peripheral Nerve Interface (RPNI) are 2 modern surgical techniques that provide neuromuscular targets for these transected nerve endings to reinnervate. These strategies have been previously shown to reduce phantom limb pain, residual limb pain, and neuroma-related pain. 1,2,7,11 Two recent articles described technical adaptations of combining targeted muscle reinnervation and RPNI to create a hybrid procedure. 3,12 In this article, we propose a different modification of targeted muscle reinnervation and RPNI, where the transected nerve stump is coapted to a recipient unit consisting of an intact distal nerve branch with its associated muscle graft. We called this recipient unit a targeted peripheral nerve interface because it contains a distal nerve branch for nerve coaptation and can guide axonal regeneration from the donor nerve to its target muscle graft. We theorize that targeted peripheral nerve interface may lead to more even distribution of regenerating axons with potentially less pain and stronger signals for prosthetic control when compared with standard RPNI., Competing Interests: Disclosure: The authors have no financial interest to declare in relation to the content of this article., (Copyright © 2021 The Authors.

The emergence of COVID-19 as a viral pandemic in early 2020 resulted in notable changes to the daily practice, workflow, and education of orthopaedic residencies internationally. In particular, social distancing, residency restructuring, and redeployment to other services has increased heterogeneity in schedules and made the in-person gathering of trainees for education increasingly challenging. These changes may last until 2024 based on some mathematical models, resulting in notable disruptions to orthopaedic education, especially for junior residents. Therefore, in this study, we describe how we converted our in-person PGY-1 skills course into a "virtual" boot camp based on validated training modules and existing American Board of Orthopaedic Surgeons guidelines. Lessons learned from the experience and potential areas for improvement in the use of newer technology to teach cognitive knowledge and skills modules are highlighted with the hope that this can be useful to other orthopaedic residency programs, during the pandemic and also beyond.

Purpose: The purpose of this study was to explore injury-related characteristics that differentiate between patient-reported outcomes (PROs) following traumatic musculoskeletal injury., Methods: We reviewed English-language articles in PubMed/MEDLINE, Google Scholar, and the Cochrane Database of Systematic Reviews (January 1995 to September 2018). We included studies that compared patient-reported outcomes of musculoskeletal trauma based on injury characteristics, and excluded studies related to development or validation of outcome tools without implementation, measurement, or comparison. Studies on patients with isolated neurotrauma or spine trauma were not included. Study level of evidence was assessed by 2 reviewers using the modified Oxford Centre for Evidence-based Medicine rating system., Results: A total of 20 studies (21 articles) that reported on a total of 10,186 patients were included (4 were prospective cohort-studies, 8 were matched-control retrospective cohort-studies, and 8 were retrospective cohort-studies). Median minimum follow-up was 3 years (range 0.5-10 years). Injury-related factors associated with worse PROs were polytrauma or multiple injuries (10 studies), neurotrauma (11 studies), and high-energy injury mechanism (7 studies). Among all studies, 32 different outcome metrics were used (17 general health status metrics and 15 limb-specific metrics) making meta-analysis infeasible., Conclusions: Based on the included studies, we propose a framework where musculoskeletal injuries occur in one of 4 scenarios that is associated with a different context-dependent outcome: (1) polytrauma with neurotrauma, (2) polytrauma without neurotrauma, (3) high-energy monotrauma, and (4) low-energy monotrauma. Our results suggest that standardization of outcome instruments is needed to facilitate future meta-analyses that assess PROs in this population.

Background: After musculoskeletal injury, US providers prescribe opioids more frequently and at higher dosages than prescribers in the Netherlands and Haiti; however, the extent of variation in nonopioid analgesic prescribing is unknown. The aim of our study was to evaluate how nonopioid prescribing by orthopaedic residents varies by geographic context., Methods: Orthopaedic residents in three countries in which residents are the primary prescribers of postoperative analgesia in academic medical centers (Haiti, the Netherlands, and the United States) responded to surveys using vignette-based musculoskeletal trauma case scenarios. The residents chose which medications they would prescribe for postdischarge analgesia. We quantified the likelihood and dose of acetaminophen or a nonsteroidal anti-inflammatory drug prescription. We constructed multivariable regressions with generalized estimating equations to describe differences in nonopiate prescription according to country, the resident's sex and training year, and the injury site and age in the test cases., Results: Compared with residents from the United States, residents from Haiti were more likely to prescribe nonopioids (odds ratio, 3.22 [confidence interval, 1.94 to 5.34], P < 0.0001) and residents from the Netherlands nearly always prescribed nonopioids. Of those cases where one or more opioid was prescribed, providers also prescribed a nonopioid (acetaminophen or nonsteroidal anti-inflammatory drug) in 345/603 (57.2%) of US, 152/152 (100%) of Dutch, and 69/97 (71.1%) of Haitian cases (Fisher exact test P value <0.0001). Finally, providers prescribed only nonopioids for pain control in 3/348 (0.86%) of US, 32/184 (17.4%) of Dutch, and 107/176 (60.8%) of Haitian cases (Fisher exact test P < 0.0001)., Conclusions: When comparing multimodal analgesic patterns, US prescribers prescribed nonopioid analgesics less frequently than prescribers in two other countries, one low income and one high income, either in isolation or in conjunction with opioids.

In this study, we assessed the patient-reported outcomes of distal humerus fracture treatment using Patient-Reported Outcomes Measurement Information System (PROMIS) or QuickDASH (Disabilities of the Arm, Shoulder, and Hand) scores and the association between patient-reported outcomes and clinical outcomes., Methods: We performed a retrospective cohort study of 76 adult patients who sustained an acute distal humerus fracture between 2016 and 2018; 53 patients completed at least one patient-reported outcome measure used to assess physical function (PF) during their routine follow-up care (69.7% response rate). The average time to follow-up patient-reported outcome measure was 10.3 months. Patients completed the PROMIS PF 10a, PROMIS upper extremity (UE) 16a, and/or QuickDASH based on the treating institution/service. In addition, the PROMIS Global (Mental) subscale score was used as a measure of self-rated mental health. To assess clinical outcomes, we measured radiographic union, range of motion, and postoperative complications., Results: Most fractures were intra-articular (67.9%), and 84.9% were treated surgically. After treatment, 98.1% of fractures united radiographically. By the final follow-up, the average arc of motion was 18° to 122°. Average (±SD) PROMIS PF and UE scores were 41.7 ± 11.1 and 40.8 ± 12.4, respectively. The average QuickDASH score was 39.4 ± 26.5. The arc of flexion-extension and PROMIS Global (Mental) score were independently associated with PROMIS PF and PROMIS UE scores., Conclusions: We found that clinical factors (the arc of flexion-extension) and patient psychological factors (PROMIS Global [Mental] score) were independently associated with PROMIS measures of PF after distal humerus fracture treatment. These data can be used to contextualize patient outcomes and guide patient expectations., Competing Interests: None of the following authors or any immediate family member has received anything of value from or has stock or stock options held in a commercial company or institution related directly or indirectly to the subject of this article: Dr. Bhashyam, Dr. Ochen, Dr. van der Vliet, Dr. Leenen, Dr. Hietbrink, Dr. Houwert, Dr. Dyer, and Dr. Heng., (Copyright © 2020 The Authors.

Purpose: Olecranon fractures are common and typically require surgical fixation due to displacement generated by the pull of the triceps muscle. The most common techniques for repairing olecranon fractures are tension-band wiring or plate fixation, but these methods are associated with high rates of implant-related soft-tissue irritation. Another treatment option is fixation with an intramedullary screw, but less is known about surgical results using this strategy. Thus, the purpose of this study was to report the clinical and functional outcomes of olecranon fractures treated with an intramedullary cannulated screw., Methods: We identified 15 patients (average age at index procedure 44 years, range 16-83) with a Mayo type I or IIA olecranon fracture who were treated with an intramedullary cannulated screw at a single level 2 trauma center between 2012 and 2017. The medical record was reviewed to assess radiographic union, postoperative range of motion and complications (including hardware removal). Patient-reported outcome was evaluated using the Disabilities of the Arm, Shoulder and Hand (DASH) score. Average follow-up was 22 months (range 8-36 months)., Results: By the 6th month post-operative visit, 14 patients had complete union of their fracture and 1 patient had an asymptomatic non-union that did not require further intervention. Average flexion was 145° (range 135-160) and the average extension lag was 11° (range 0-30). Implants were removed in 5 patients due to soft-tissue irritation. Average DASH score (± standard deviation) by final follow-up was 16 ± 10., Conclusions: Fixation of simple olecranon fractures with an intramedullary screw is a safe and easy fixation method in young patients, leading to good functional and radiological results. Compared to available data, less hardware removal is necessary than with tension-band wiring or plate fixation.

Dorsal Barton fractures may be better described as variants of dorsal radiocarpal dislocations. We aimed to better characterize these fractures by reviewing 111 patients in the ICUC® dataset who had a dorsally displaced, intra-articular distal radius fracture. We identified 13 patients with a dorsal Barton fracture on radiographs (dorsal articular margin fracture with radiocarpal subluxation and intact volar cortex). All patients with a dorsal Barton fracture had radial styloid involvement and volar cortical disruption that was subsequently identified on three-dimensional CT. Based on three-dimensional CT and intra-operative findings, none of the patients had classically described dorsal Barton fractures. All patients were treated using a volar exposure. A volar capsular tear was identified intra-operatively in three patients and the volar capsule repaired. This series supports the contention that dorsal Barton fractures are better characterized and treated as a variation of a dorsal radiocarpal dislocation. Level of evidence: IV.

Background: In 2016, our provider group adopted an initial prescription opioid maximum guideline to reduce overprescription of opioids. The purpose of this study was to prospectively assess opioid consumption patterns following implementation of this guideline in patients undergoing outpatient foot and ankle surgery., Methods: Over a 1-year period, we prospectively analyzed opioid prescription and use patterns of 303 consecutive patients. Opioid consumption was verified by pill counts completed at the 2- and 6-week postoperative visits. The morphine equivalent dose was calculated for each prescription and converted to the equivalent 5-mg oxycodone "pill." We used the regression coefficients from a regression model of opioid consumption to create a revised guideline for maximum initial opioid prescriptions based on patient age, bony vs nonbony procedure, and anatomic location (forefoot/midfoot/hindfoot/ankle)., Results: On average, 37.4 pills were prescribed and 18.9 pills used (47.6% utilization). Only 17.2% of patients used their full prescription quantity. By 2 weeks, 88% of patients no longer used opioids. Only 1.3% of patients used prescription opioids beyond 6 weeks. Independent risk factors for increased opioid consumption were younger age ( P = .003), male sex ( P = .007), recent preoperative opioid use ( P = .019), bony procedures ( P < .001), and ankle/hindfoot procedures ( P = .016 and P < .001)., Conclusion: This study showed the amount of opioid consumption for patients undergoing foot and ankle procedures. We present a modified guideline for the maximum initial prescription of opioids following outpatient foot and ankle procedures that can be used as a benchmark for further study in decreasing overprescribing., Level of Evidence: Level II, prospective observational cohort study.

Purpose: Routine collection of post-discharge patient-reported outcomes within trauma registries can be used to benchmark quality of trauma care. This process is dependent on geographic and cultural context, but results are lacking regarding the European experience. We aimed to investigate the feasibility of routine inclusion of longer-term patient-reported health-related quality of life (HRQoL) in a Dutch National Trauma Database (DNTD) and to characterize these outcomes in a prospective cohort study., Methods: All adult patients (≥ 18 years) who presented for traumatic injury in 2015-2016 and met the inclusion criteria of the DNTD were included. Inclusion criteria of the DNTD are presence of traumatic injury, hospital presentation within 48 h from trauma and hospital admission for treatment of traumatic injury or immediate mortality from traumatic injury after presentation. Exclusion criteria were death, mental impairment, insufficient command of Dutch language and residency outside the Netherlands. Primary outcomes were process-related measures of feasibility (response rate, response methods and reasons for non-response). Secondary outcomes were HRQoL measures [EuroQOL 5-Dimensions 3-Level (EQ-5D-3L) with added cognitive dimension and Visual Analogue Scale (EQ-VAS)]., Results: 2025 unique patients met the initial inclusion criteria, with 1753 patients eligible for follow-up. Of these, 1315 patients participated (response rate 75%). The majority of questionnaires, 990 (75%), were completed on paper, with an additional 325 (25%) through telephone interviews. Primary reason for non-response was lack of contact information (245/438 non-responders; 56%). Median EQ-5D score was 0.81 (IQR 0.68-1.00) (mean 0.74; SD 0.31) and median EQ-VAS score was 78 (IQR 65-90). Compared to a Dutch reference population (mean EQ-5D = 0.87), EQ-5D scores were significantly lower (p < 0.001)., Conclusions: Routine collection of HRQoL is feasible within European health systems, like in the Netherlands. Further integration of these measures into trauma registries may aid worldwide benchmarking of trauma care quality.

Background: Patient-reported outcomes (PROs) are increasingly relevant when evaluating the treatment of orthopaedic injuries. Little is known about how PROs may vary in the setting of polytrauma or secondary to high-energy injury mechanisms, even for common injuries such as distal radius fractures., Questions/purposes: (1) Are polytrauma and high-energy injury mechanisms associated with poorer long-term PROs (EuroQol Five Dimension Three Levels [EQ-5D-3L] and QuickDASH scores) after distal radius fractures? (2) What are the median EQ-5D-3L, EQ-VAS [EuroQol VAS], and QuickDASH scores for distal radius fractures in patients with polytrauma, high-energy monotrauma and low-energy monotrauma METHODS: This was a retrospective study with followup by questionnaire. Patients treated both surgically and conservatively for distal radius fractures at a single Level 1 trauma center between 2008 and 2015 were approached to complete questionnaires on health-related quality of life (HRQoL) (the EQ-5D-3L and the EQ-VAS) and wrist function (the QuickDASH). Patients were grouped according to those with polytrauma (Injury Severity Score [ISS] ≥ 16), high-energy trauma (ISS < 16), and low-energy trauma based on the ISS score and injury mechanism. Initially, 409 patients were identified, of whom 345 met the inclusion criteria for followup. Two hundred sixty-five patients responded (response rate, 77% for all patients; 75% for polytrauma patients; 76% for high-energy monotrauma; 78% for low-energy monotrauma (p = 0.799 for difference between the groups). There were no major differences in baseline characteristics between respondents and nonrespondents. The association between polytrauma and high-energy injury mechanisms and PROs was assessed using forward stepwise regression modeling after performing simple bivariate linear regression analyses to identify associations between individual factors and PROs. Median outcome scores were calculated and presented., Results: Polytrauma (intraarticular: β -0.11; 95% confidence interval [CI], -0.21 to -0.02]; p = 0.015) was associated with lower HRQoL and poorer wrist function (extraarticular: β 11.9; 95% CI, 0.4-23.4; p = 0.043; intraarticular: β 8.2; 95% CI, 2.1-14.3; p = 0.009). High-energy was associated with worse QuickDASH scores as well (extraarticular: β 9.5; 95% CI, 0.8-18.3; p = 0.033; intraarticular: β 11.8; 95% CI, 5.7-17.8; p < 0.001). For polytrauma, high-energy trauma, and low-energy trauma, the respective median EQ-5D-3L outcome scores were 0.84 (range, -0.33 to 1.00), 0.85 (range, 0.17-1.00), and 1.00 (range, 0.174-1.00). The VAS scores were 79 (range, 30-100), 80 (range, 50-100), and 80 (range, 40-100), and the QuickDASH scores were 7 (range, 0- 82), 11 (range, 0-73), and 5 (range, 0-66), respectively., Conclusions: High-energy injury mechanisms and worse HRQoL scores were independently associated with slightly inferior wrist function after wrist fractures. Along with relatively well-known demographic and injury characteristics (gender and articular involvement), factors related to injury context (polytrauma, high-energy trauma) may account for differences in patient-reported wrist function after distal radius fractures. This information may be used to counsel patients who suffer a wrist fracture from polytrauma or high-energy trauma and to put their outcomes in context. Future research should prospectively explore whether our findings can be used to help providers to set better expectations on expected recovery., Level of Evidence: Level III, therapeutic study.

Background: Little is known about the effect of orthopaedic trauma on the financial health of patients. We hypothesized that some patients who sustain musculoskeletal trauma experience considerable financial hardship during treatment, and we also assessed for factors associated with increased personal financial burden., Methods: We surveyed 236 of 393 consecutive patients who were approached at 1 of 2 American College of Surgeons level-I trauma centers between 2016 and 2017 following the completion of treatment for a musculoskeletal injury (60% response rate). Two validated measures (financial burden composite score and dichotomized worry score) were used to assess the financial hardship that patients experienced with the injury., Results: There were 236 participants in the study, the mean age was 56.3 years (range, 19 to 94 years), and 48.7% of patients were male. Of the 236 patients, 97.9% had medical insurance, yet the mean financial burden composite score (and standard deviation) was 2.4 ± 2.2 (0 indicated low and 6 indicated high). In this study, 25.0% of patients had high levels of worry about financial problems that resulted from the injury. Fifty-four percent of patients used their savings to pay for their care, and 23% of patients borrowed money or took out a loan. Twenty-three percent of patients missed payment on other bills. Fifty-seven percent of patients were required to cut expenses in general. Patients with higher composite financial burden scores had a significantly increased likelihood of high financial worry (odds ratio [OR], 1.8 [95% confidence interval (CI), 1.5 to 2.2]; p < 0.001). Factors associated with increased financial hardship were high-deductible health plan insurance (coefficient, 0.3 [95% CI, 0.002 to 0.528]; p = 0.048), Medicaid insurance (coefficient, 0.6 [95% CI, 0.342 to 0.863]; p < 0.001), failure to complete high school (coefficient, 0.475 [95% CI, 0.033 to 0.918]; p = 0.035), increased number of surgical procedures (coefficient, 0.067 [95% CI, 0.005 to 0.129]; p = 0.035), and prior medical or student loans (coefficient, 0.769 [95% CI, 0.523 to 1.016]; p < 0.001)., Conclusions: Despite a high rate of insurance, patients with orthopaedic trauma in our study had high rates of worry and financial distress. Asking about financial hardship may help to identify those patients with a higher personal financial burden and may promote allocation of additional social support and services.

Background: The extent of variation in analgesic prescribing following musculoskeletal injury among countries and cultural contexts is poorly understood. Such an understanding can inform both domestic prescribing and future policy. The aim of our survey study was to evaluate how opioid prescribing by orthopaedic residents varies by geographic context., Methods: Orthopaedic residents in 3 countries in which residents are the primary prescribers of postoperative analgesia in academic medical centers (Haiti, the Netherlands, and the U.S.) responded to surveys utilizing vignette-based musculoskeletal trauma case scenarios. The residents chose which medications they would prescribe for post-discharge analgesia. We standardized opioid prescriptions in the surveys by conversion to morphine milligram equivalents (MMEs). We then constructed multivariable regressions with generalized estimating equations to describe differences in opiate prescription according to country, the resident's sex and training year, and the injury site and age in the test cases., Results: U.S. residents prescribed significantly more total MMEs per case (mean [95% confidence interval] = 383 [331 to 435]) compared with residents from the Netherlands (229 [160 to 297]) and from Haiti (101 [52 to 150]) both overall (p < 0.0001) and for patients treated for injuries of the femur (452 [385 to 520], 315 [216 to 414], and 103 [37 to 169] in the U.S., the Netherlands, and Haiti, respectively), tibial plateau (459 [388 to 531], 280 [196 to 365], and 114 [46 to 183]), tibial shaft (440 [380 to 500], 294 [205 to 383], and 141 [44 to 239]), wrist (239 [194 to 284], 78 [36 to 119], and 63 [30 to 95]), and ankle (331 [270 to 393], 190 [100 to 280], and 85 [42 to 128]) (p = 0.0272). U.S. residents prescribed significantly more MMEs for patients <40 years old (432 [374 to 490]) than for those >70 years old (327 [270 to 384]) (p = 0.0019)., Conclusions: Our results demonstrate greater prescribing of postoperative opioids at discharge in the U.S. compared with 2 other countries, 1 low-income and 1 high-income. Our findings highlight the high U.S. reliance on opioid prescribing for postoperative pain control after orthopaedic trauma., Clinical Relevance: Our findings point toward a need for careful reassessment of current opioid prescribing habits in the U.S. and demand reflection on how we can maximize effectiveness in pain management protocols and reduce provider contributions to the ongoing opioid crisis.
