Graves' disease has a multitude of presentations, and certain symptoms can mimic sports-related concerns such as overtraining. A review of three cases of Graves' disease in young athletes illustrates the spectrum of symptoms and the pathophysiology. Diagnosis involves a detailed patient history, physical exam, and appropriate lab studies, including a thyroid radioactive iodine uptake scan. Treatment consists of symptom management and antithyroid medication, radioactive iodine thyroid ablation, or, rarely, thyroidectomy. [ABSTRACT FROM AUTHOR]

STUDY DESIGN.: Cross-sectional survey. OBJECTIVE.: The objective of this study was to investigate the authorship, content, and quality of information available to the public on the Internet pertaining to the cervical artificial disc replacement device. SUMMARY OF BACKGROUND DATA.: The Internet is widely used by patients as an educational tool for health care information. In addition, the Internet is used as a medium for direct-to-consumer marketing. Increasing interest in cervical artificial disc replacement has led to the emergence of numerous Web sites offering information about this procedure. It is thought that patients can be influenced by information found on the Internet. METHODS.: A cross section of Web sites accessible to the general public was surveyed. Three commonly used search engines were used to locate 150 (50/search engine) Web sites providing information about the cervical artificial disc replacement. Each Web site was evaluated with regard to authorship and content. RESULTS.: Fifty-three percent of the Web sites reviewed were authorized by a private physician group, 4% by an academic physician group, 13% by industry, 16% were news reports, and 14% were not otherwise categorized. Sixty-five percent of Web sites offered a mechanism for direct contact and 19% provided clear patient eligibility criteria. Benefits were expressed in 80% of Web sites, whereas associated risks were described in 35% or less. European experiences were noted in 17% of Web sites, whereas only 9% of Web sites detailed the current US experience. CONCLUSION.: The results of this study demonstrate that much of the content of the Internet-derived information pertaining to the cervical artificial disc replacement is for marketing purposes and may not represent unbiased information. Until we can confirm the content on a Web site to be accurate, patients should be cautioned when using the Internet as a source for health care information related to cervical disc replacement.

Obesity has become a leading public health issue in the United States. The goal of this study was to examine whether patients experience a significant change in body mass index (BMI) or weight after total joint arthroplasty. Previous studies have not corrected for the natural, annual positive BMI change in North Americans aged 29 to 73 years. Our study takes this natural weight gain into consideration in examination of total hip arthroplasty and total knee arthroplasty (TKA) populations. Our study population trended toward weight loss and BMI loss when weight was corrected for natural gain. Clinically significant weight loss, as determined by US Food and Drug Administration parameters, occurred in 19.9% of the study population when weight was corrected for natural gain. The TKA population exhibited a statistically significant (P<.05) weight loss and a clinically significant weight loss in 21.5% of the population. Patients with an initial BMI >30 exhibited a trend toward weight loss. This study was a level II retrospective study. [ABSTRACT FROM AUTHOR]

Herniated disks in the lumbar spine are the leading cause of patient visits to spinal surgeons in the United States. Although magnetic resonance imaging (MRI) is the diagnostic test of choice in patients with a herniated disk, plain radiographs can provide important information and should remain a standard part of the diagnostic workup in any patient indicated for revision spine surgery. This article describes a case of a 36-year-old man with a >6-month history of worsening lumbar radiculopathy who was diagnosed with lumbar disk herniations based on MRI alone and underwent 2 unsuccessful attempts at microdiskectomy at another institution. Further workup by the senior author (A.C.H.), which included initial plain radiographs followed by computed tomography, demonstrated a large disk herniation with a markedly calcified annulus as the continuing source of neurologic compression. The patient underwent revision lumbar decompression with attention being paid to the removal of the calcified annulus and disk material that resulted in complete resolution of his symptoms. Although MRI is the diagnostic test of choice in the evaluation of spinal pathology, plain radiographs can provide important additional information that can be vital to the successful outcome of patients undergoing revision spinal surgery.

Background: Brachial plexus birth injury (BPBI) is common and while most recover, 8-36% of patients experience permanent impairment. Typically, adolescents with untreated BPBI lack active and passive external shoulder rotation (ER) and overhead shoulder function. Limited shoulder function is due to 1) nonoperative BPBI 2) untreated BPBI or 3) unrecognized glenohumeral joint dysplasia. We describe a technique for achieving reanimation in adolescents who did not receive timely/effective BPBI care, a postoperative rehabilitation protocol, and results from a series of eight patients who underwent shoulder reanimation., Methods: A comprehensive shoulder reanimation approach is performed. Anteriorly, the pectoralis minor, major, and anterior capsule necessitate release. In severe dysplasia, a coracoidectomy, posterior glenoid osteotomy, and/or subscapularis slide may be necessary. Acromial dysplasia is also common, frequently necessitating osteoplasty. The deltoid is usually nonfunctional, and we use a bipolar latissimus muscle transfer for reanimating abduction and forward flexion. To assist with ease of rehabilitation we will often transfer the tendon of the teres major. Levator scapulae transfer to the supraspinatus is often performed to assist with the initiation of abduction. For external rotation, the ipsilateral lower trapezius is used. Finally, ipsilateral rhomboid advancement and contralateral lower trapezius muscle transfer is performed for dynamic scapular stabilization. After surgery, all patients participated in our rigorous postoperative rehabilitation protocol., Results: Eight patients (13.8±5.6 years, 35±24 weeks follow-up) were included. All patients participated in our rehabilitation protocol. Preoperatively, patients generally achieved 0° ER from neutral and in maximum abduction. Postoperatively, patients achieved an average of 71° (30-90°) ER from neutral and an average of 82° (65-90°) ER in maximum abduction. Preoperatively, patients generally had 0-20° of abduction, which they achieved through scapulothoracic motion. Postoperatively, patients could achieve an average of 115° (90-180°) of abduction. Preoperatively, patients had 0-20° of FF that was mediated through scapulothoracic motion. Postoperatively, patients' FF increased to an average of 91° (20-170°)., Conclusion: This technique is intended to restore a congruent glenohumeral joint and reanimate structures allowing for abduction, FF, and ER. While we advocate for early treatment of BPBI, applying this technique to undertreated/untreated adolescent patients paired with our rehabilitation protocol results in significant functional improvement, allowing for an improved quality of life., (Copyright © 2024 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Brachial plexus birth injury (BPBI) encompasses a spectrum of upper extremity paralysis cases following childbirth. The etiology of BPBI is multifactorial, involving maternal, obstetric, and neonatal associative factors. Despite opportunities for spontaneous recovery, recent literature demonstrates that a significant proportion of infants experience residual deficits and functional limitations as they age. Understanding the complex anatomy of the brachial plexus, clinical presentations of the pathology, diagnostic workup, current treatment options, and common secondary sequelae is instrumental for appropriate management of BPBI., Methods: Following a comprehensive search strategy used by the authors to identify relevant literature relating to the progression, patho-anatomy, clinical presentation, management, and treatment of BPBI, this comprehensive narrative review outlines current approaches to assess, manage, and advance BPBI care., Results: We advocate for prompt referral to specialized multicenter brachial plexus clinics for accurate diagnosis, timely intervention, and individualized patient-centered assessment. Further research is needed to elucidate mechanisms of injury, refine diagnostic protocols, and optimize long-term outcomes., Conclusions: Collaboration between healthcare providers and families is paramount in providing comprehensive care for infants with BPBI. This review offers insights into the current understanding and management of BPBI, highlighting the importance of tailored approaches and intraoperative decision-making algorithms to optimize functional outcomes., Competing Interests: Steven M.

Background: Apert syndrome is a relatively rare genetic disorder with a constellation of distinct craniofacial deformities and bilateral syndactyly of the hands and feet. Although the literature contains ample evidence for the need to treat cranial, midfacial, and hand abnormalities, there are severe shortcomings in the literature when attempting to describe the pathology and management of the entire upper limb in patients with Apert syndrome., Methods: A thorough literature search was performed using PubMed, Scopus, Web of Science, and Google Scholar, on the management of the upper extremity in Apert syndrome, including the shoulder, elbow, and hand., Results: Our findings of the literature discuss the clinical presentation and management trends of the upper extremity in patients with Apert syndrome. Through multicenter collaboration, discussion among experts in the field, and evidence gathered from the literature, we propose treatment algorithms to treat deformities of the hand, shoulder, and elbow in patients with Apert syndrome., Conclusions: This review identifies that even if hand pathologies have been correctly treated, shoulder and elbow abnormalities in patients with Apert syndrome are largely ignored. To optimize outcomes, added cognizance of additional upper limb congenital differences and their management should be highly advocated in this patient population., Competing Interests: Dr. Koehler is a committee member of the American Society for Surgery of the Hand, and a stockholder and member of the medical advisory board for Reactiv, Inc.

Background and Objectives: Despite the high morbidity associated with glenohumeral dysplasia (GHD) in children with brachial plexus birth injuries, the progression of this condition often remains unnoticed, even after correcting for the underlying brachial plexus birth injuries. GHD, driven by a multifactorial process involving disruptions in both direct and indirect neural regulation of bony and muscular structures, can lead to intermittent or permanent shoulder mobility imbalances, significantly impacting the quality of life of those affected. Recent research efforts are increasingly directed toward identifying the root causes, managing the deformity, and determining effective treatment options for correcting GHD., Methods: A comprehensive search strategy was used by the authors to identify relevant literature relating to the progression, pathoanatomy, clinical presentation, and management of GHD following brachial plexus birth injuries across various search engines, such as PubMed, Scopus, and Embase. Considering the topic's interdisciplinary nature, articles were retrieved from both neurosurgical and orthopaedic journals to enrich the review., Results: Given the challenges in managing patients with brachial plexus birth injuries, a multidisciplinary care team consisting of certified occupational hand therapists, neurosurgeons, plastic surgeons, and orthopedic surgeons, specializing in brachial plexus injuries should be advocated for. The aim of this collaborative effort is to correct brachial plexus birth injuries and prevent the persistence of GHD., Conclusion: As research continues to focus on understanding the complexities of this condition, the aim of this review article is to summarize the current literature on the course of brachial plexus birth injury and the development of GHD. By doing so, we hope to provide neurosurgeons with the necessary knowledge and essential tools needed to identify and effectively treat GHD during management of brachial plexus birth injuries., (Copyright © Congress of Neurological Surgeons 2024.

Background: The purpose of this study was to perform a biomechanical investigation on the effect of ulnar variance (UV) on the stability of the distal radioulnar joint (DRUJ) prior to and after DRUJ sectioning., Methods: Ten cadaveric forearm specimens were included in the study and baseline UV was assessed radiographically. Radial motion relative to the ulna was evaluated using Intel real sense cameras and a custom developed program. The forearms were dissected, and a radial osteotomy was performed. Using a custom-made plate, radial stability was assessed with an UV of + 4, 0, and -4 mm by measuring the maximum and minimum radial position relative to the ulna during a simulated Shuck test. The volar radioulnar ligaments and triangular fibrocartilage complex (TFCC) were then sectioned, and testing was repeated at each UV state., Results: Sectioning significantly increased radial translation at neutral ( P = .008), +4 mm UV ( P = .008), and -4 mm UV ( P = .018). There were no significant differences in translation between the 3 UV groups with the DRUJ intact ( P = .124). The ulnar negative (-4 mm) state had significantly lower translation compared to the positive (+4 mm) ( P < .001) and the neutral (0 mm) ( P = .026) UV states. There were no significant differences between the positive and neutral UV groups with the DRUJ sectioned., Conclusions: Fixating the radius in -4 mm of ulnar negativity significantly decreased radial translation after sectioning the volar radioulnar ligament and TFCC. Ulnar variance had no effect on stability with an intact DRUJ., Study Type: Biomechanical Study., 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: S.K. has received past speaker honorarium from TriMed, Inc.

Purpose: Brachial plexus birth injury (BPBI) is a common injury with the spectrum of disease prognosis ranging from spontaneous recovery to lifelong debilitating disability. A common sequela of BPBI is glenohumeral dysplasia (GHD) which, if not addressed early on, can lead to shoulder dysfunction as the child matures. However, there are no clear criteria for when to employ various surgical procedures for the correction of GHD., Methods: We describe our approach to correcting GDH in infants with BPBIs using a reverse end-to-side (ETS) transfer from the spinal accessory to the suprascapular nerve. This technique is employed in infants that present with GHD with poor external rotation (ER) function who would not necessitate a complete end-to-end transfer and are still too young for a tendon transfer. In this study, we present our outcomes in seven patients., Results: At presentation, all patients had persistent weakness of the upper trunk and functional limitations of the shoulder. Point-of-care ultrasounds confirmed GHD in each case. Five patients were male, and two patients were female, with a mean age of 3.3 months age (4 days-7 months) at presentation. Surgery was performed on average at 5.8 months of age (3-8.6 months). All seven patients treated with a reverse ETS approach had full recovery of ER according to active movement scores at the latest follow-up. Additionally, ultrasounds at the latest follow-up showed a complete resolution of GHD., Conclusion: In infants with BPBI and evidence of GHD with poor ER, end-to-end nerve transfers, which initially downgrade function, or tendon transfers, that are not age-appropriate for the patient, are not recommended. Instead, we report seven successful cases of infants who underwent ETS spinal accessory to suprascapular nerve transfer for the treatment of GHD following BPBI., (© 2024. The Author(s).)

We investigated the efficacy of the supination-external rotation ('Sup-ER') orthosis, designed as a non-operative treatment to maintain normal anatomical growth of the shoulder, on the progression of glenohumeral dysplasia in patients with brachial plexus birth injuries. The Sup-ER orthosis was fabricated for 20 infants diagnosed with glenohumeral dysplasia after brachial plexus birth injuries and its success in correcting glenohumeral dysplasia was confirmed by objective calculations of the alpha angle on serial ultrasound findings and improvement in Active Movement Scale scores. Of the 20 patients, 14 had successful resolution of glenohumeral dysplasia, confirmed by shoulder abduction, shoulder flexion, external rotation and supination, Active Movement Scale scores and improving alpha angle measurements. Failure to rectify glenohumeral dysplasia, evidenced by worsening ultrasound findings and Active Movement Scale scores, necessitated a change to operative management in six patients.

Brachial plexus birth injury (BPBI) is a relatively common condition that poses a significant challenge to children who endure functional impairments later on. This comprehensive bibliometric analysis sought to quantitatively evaluate the existing literature on BPBI, shedding light on authorship, collaboration, publication trends, and keyword analysis to both inform the medical community and foster future research growth. A thorough search of the Web of Science database yielded 712 relevant documents published between 1986 and 2022. The analysis utilized Biblioshiny (K-Synth Srl, Naples, Italy) for bibliometric data, alongside VOSviewer (Centre for Science and Technology Studies, Leiden University, The Netherlands) and TextRazor (TextRazor Ltd., London, UK) for keyword categorization. The literature had an average annual growth rate of 7.94%, with an average document age of 12 years. Collaborative efforts demonstrated 9.6% international co-authorship, with the United States prominently leading global collaborations. Top producing authors included Yang, Kozin, and Clarke, while the most cited authors were Clarke, Waters, and Curtis. Journals such as the Journal of Pediatric Orthopedics and Plastic and Reconstructive Surgery emerged as key contributors to the literature. Keyword analysis illuminated prevalent categories like "society" and "health," underscoring the multifaceted nature of BPBI research. The findings from this bibliometric analysis highlight the dynamic and collaborative landscape of BPBI research, emphasizing the pressing need for continued contributions to address existing gaps in knowledge, enhance global collaboration, and advance the understanding and treatment of this complex condition. Beyond quantitative metrics, this study holds particular significance in its role as a compass for researchers, practitioners, and policymakers invested in BPBI. By offering insights into influential authors, institutions, and emerging trends, this analysis serves as a valuable resource, guiding future research endeavors, fostering interdisciplinary collaboration, and ultimately contributing to improved outcomes for individuals affected by BPBI. The importance of this study lies not only in its informative content but also in its potential to catalyze a collective effort toward refining treatment modalities, promoting preventative measures, and enhancing the overall quality of care for those navigating the challenges of BPBI., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2024, Hoffman et al.)

Background: Previous studies have suggested that proximal row carpectomy (PRC) results in increased contact pressures and decreased contact areas in the radiocarpal joint. Such experiments, however, used older technologies that may be associated with considerable measurement errors. The purpose of this study was to determine whether there was a significant difference in contact pressure and contact area before and after PRC using Tekscan, a newer pressure sensing technology., Methods: Ten nonpaired cadaveric specimens were dissected proximal to the carpal row and potted. An ultra-thin Tekscan sensor was secured in the lunate fossa of the radius. The wrists were loaded with 200 N of force for 60 seconds to simulate clenched-fist grip; contact pressure and area was assessed before and after PRC., Results: Performing a PRC did not significantly increase mean contact pressure at the lunate fossa compared to the native state (mean increase of 17.4 ± 43.2 N/cm 2 , P = .184). Similarly, the PRC did not significantly alter peak contact pressures at the lunate fossa (intact: 617.2 ± 233.46 N/cm 2 , median = 637.5 N/cm 2 ; PRC: 707.8 ± 156.6 N/cm 2 , median = 728.5 N/cm 2 ; P = .169). In addition, the PRC (0.46 ± 0.15 cm 2 , median = 0.48 cm 2 ) and intact states (0.49 ± 0.25 cm 2 , median = 0.44 cm 2 ) demonstrated similar contact areas ( P = .681)., Conclusions: In contrast to prior studies that demonstrated significant increases in contact pressure and decreases in contact area after PRC, our findings propose that performing a PRC does not significantly alter the contact pressures or area of the lunate fossa of the radiocarpal joint., 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: S.K. is a committee member of the American Society for Surgery of the Hand (ASSH); a paid consultant and speaker for Integra LifeSciences, Inc; a paid consultant for Tissium, Inc.; a stockholder and member of the medical advisory board for Reactiv, Inc.; and a speaker for TriMed, Inc.

Background: Surgical approaches to the proximal interphalangeal (PIP) joint often require disruption of soft tissue stabilizers. Additionally, PIP joint injuries frequently result in soft tissue disruption. This study evaluates the necessity of repairing soft tissue stabilizers by assessing their role in maintaining native joint congruity., Methods: Eight specimens were used to evaluate congruity at 0° and 30° flexion when loaded with 2 N of valgus force. This was performed in the native joint and after sequential sectioning of the surrounding ligaments in order: volar plate (VP), radial collateral ligament (CL), and ulnar CL. The skin flap was sutured with the ligaments unrepaired and the load was reapplied. Radiographs were taken after each load and used to measure the joint line convergence angle (JLCA)., Results: Mean JLCA increased in both degrees of flexion after ligaments were sectioned but was only significantly different from the native joint after the VP was disrupted along with 1 CL. Joint congruity improved following repair of the skin flap in both degrees of flexion but was not significant. Joints were more congruent in 30° flexion for all subgroups, but none were significantly different compared to 0° flexion., Conclusions: Disruption of the VP is insufficient to significantly alter PIP joint congruity. While sectioning of both the VP and CLs resulted in a statistically significant change in joint congruity, mean JLCA demonstrated changes of minor clinical significance. The osseous anatomy of the phalanges imparts inherent stability that maintains a congruent joint despite loss of the soft tissue stabilizers.

Background: In nonoperative management of displaced olecranon fractures, patients are able to maintain overhead extension despite a persistent nonunion. It has been hypothesized that this is feasible because of an intact lateral cubital retinaculum. The purpose of this biomechanical study was to determine the contribution of the medial and lateral cubital retinacula to overhead extension in the setting of a displaced olecranon fracture., Methods: Eight fresh-frozen cadaveric upper-extremity specimens were used in this study. The triceps muscle was loaded through a pulley system operated by an Instron 8874 Biaxial Servohydraulic Fatigue Testing System at a rate of 10 mm/second to simulate overhead elbow extension. Each specimen was tested in 4 states: (1) native state with an intact olecranon; (2) transverse olecranon fracture; (3) transection of 1 cubital retinaculum (medial or lateral); and (4) transection of both medial and lateral cubital retinacula. The primary outcome was the ability to perform overhead extension. The secondary outcome was the force needed to generate extension., Results: Elbow extension was noted in each specimen for trials 1, 2, and 3. Only when both the lateral fascia and medial fascia were transected was elbow extension not achieved. There was no significant difference in the force required to generate extension in the first 3 trials (P = .99). There was no significant difference in the change in the maximum force required to achieve extension between the specimens with only the medial side transected and the specimens with only the lateral side transected (P = .07)., Discussion: In the setting of an olecranon fracture, this biomechanical study suggests that if either the lateral or medial cubital retinaculum remains in continuity with the distal ulna, active overhead extension can be maintained. This finding may explain the positive clinical outcomes of nonoperative management of displaced olecranon fractures in the elderly patient population. Determining the integrity of the fascial structures preoperatively may help select candidates for nonoperative treatment of displaced olecranon fractures., (Copyright © 2023 Journal of Shoulder and Elbow Surgery Board of Trustees.

Evaluating the impact of articles can be performed through bibliometric analysis or social media impact using the Altmetric Attention Score (AAS). The purpose of this study was to report on the social media impact of peripheral nerve studies; how article demographic factors, such as journal specialty (hand, orthopedics, plastic surgery), affect AAS; and how AAS correlates with bibliometrics, namely citation number. While orthopedic journals received the highest academic attention, there was no significant difference in social media attention between journal groups. These findings suggest AAS may be useful to authors in deciding which journal in which to pursue publication. [ Orthopedics . 2023;46(3):e143-e148.].

Background: Upper extremity (UE) microsurgical reconstruction relies upon proper wound healing for optimal outcomes. Cigarette smoking is associated with wound healing complications, yet conclusions vary regarding impact on microsurgical outcomes (replantation, revascularization, and free tissue transfer). We investigated how smoking impacted 30-day standardized postoperative outcomes following UE microsurgical reconstruction. Methods: Utilizing the National Surgical Quality Improvement Program, all patients who underwent (1) UE free flap transfer (n = 70) and (2) replantation/revascularization (n = 270) were identified. For each procedure, patients were stratified by recent smoking history (current smoker ≤1-year preoperatively). Baseline demographics and standardized 30-day complications, reoperations, and readmissions were compared between smokers and nonsmokers. Results: Replantation/revascularization patients had no differences in sex, race, or body mass index between smokers (n = 77) and nonsmokers. Smokers had a higher prevalence of congestive heart failure (5.2% vs 1.0%, P = .036) and nonsmokers were more often on hemodialysis (15.6% vs 10.4%, P = .030). Free flap transfer patients had no differences in age, sex, or race between smokers (n = 14) and nonsmokers. Smokers had a longer length of stay (6.6 vs 4.2 days, P = .001) and a greater prevalence of chronic obstructive pulmonary disorder (COPD; 7.1% vs 0%, P = .044). Recent smoking was not associated with increased odds of any 30-day minor and major standardized surgical complications, readmissions, or reoperations following UE microsurgical reconstruction via free flap transfer or replantation/revascularization. Baseline diagnosis of COPD was also not a predictor of adverse 30-day outcomes following free flap transfer. Conclusion: Recent smoking history was not associated with any 30-day adverse outcomes following UE microsurgical reconstruction via replantation/revascularization or free flap transfer. In light of these findings, further investigation is warranted, with particular focus on adverse events specific to free flaps and replantation/revascularization., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: S.M.

The wide awake local anesthesia no tourniquet (WALANT) technique has been proven to be safe and effective for upper extremity surgery. WALANT does not require extensive medical clearance and allows for intraoperative assessment of range of motion. Additionally, it is frequently associated with lower costs and less postoperative pain when compared with traditional methods of anesthesia. Despite its expanded use for hand procedures, there are sparse data to support the use of WALANT in local and regional soft tissue flaps., Methods: A retrospective review was performed. Twenty-one patients who underwent a local or regional soft tissue flap surgery using the WALANT technique from February 2, 2018 to February 25, 2022 were included in our analysis., Results: Overall, one Louvre flap, two posterior tibial artery perforator propeller flaps, two reverse radial forearm flaps, two Quaba flaps, six cross finger flaps, one reverse homodigital island flap, three first dorsal metacarpal artery flaps, two thenar flaps, and two Moberg flaps were performed. Patients were followed up for an average of 11.9 ± 8.1 weeks. During this time, no postoperative complications occurred. All patients demonstrated appropriate healing at donor and recipient sites. Full range of motion was regained for all patients., Conclusions: WALANT is safe and effective for use in local and regional soft tissue flap surgery. Surgeons should consider this technique for more involved procedures such as flap surgery, as preliminary results demonstrate positive outcomes and potentially superior recovery for patients., Competing Interests: Disclosure: Dr. Koehler is a committee member of the American Society for Surgery of the Hand (ASSH), a paid consultant and speaker for Integra LifeSciences, Inc, a paid consultant for Tissium, Inc., a stockholder and member of the medical advisory board for Reactiv, Inc., and a speaker for TriMed, Inc.

Purpose: Differences in range of motion, pinch strength, biomechanical strength, or joint angulation have previously been investigated for various means of treatment of ulnar collateral ligament (UCL) tears. We sought to address a gap in the literature by comparing thumb metacarpophalangeal (MCP) joint angle measurements and biomechanical strength before complete, acute UCL tear and after repair with suture anchors (SA), suture tape (ST) anchor augmentation, or reconstruction with palmaris longus graft (PL)., Methods: Thumbs and, if present, the PL tendon were harvested from 15 fresh-frozen cadavers. Each thumb specimen was secured into a servohydraulic biomechanical testing frame to evaluate native radiographic MCP joint angles at 0° flexion when loaded with 0, 5, and 13 N of radial force. Subsequently, a single hand surgeon (S.M.K.) performed complete transection and UCL repair via 1 of 3 methods: SA (n = 5), ST (n = 5), or reconstruction with PL (n = 5). Following repair, MCP joint angles were radiographically evaluated. Specimens that did not fail during joint angle testing were transferred to a separate testing frame for load-to-failure testing. Angle measurements and mean load-to-failure were compared between the groups, and angulation was also compared with each group's native control., Results: Both ST and SA groups demonstrated comparable stiffness to their native controls, whereas the PL group was significantly more lax. The ST repair was significantly stiffer than the other constructs. ST also required higher forces to reach failure compared to both SA and PL. No difference was found between SA and PL groups., Conclusions: Although both ST and SA constructs recapitulate native joint stiffness, repair with ST demonstrated the greatest biomechanical strength in stiffness and load-to-failure., Clinical Relevance: For complete, acute tears of the thumb UCL, ST may be superior for maintaining MCP joint stability and strength over SA and PL., (Copyright © 2023 American Society for Surgery of the Hand.

Background: The recently validated Hand Questionnaire (HAND-Q) is a multifaceted patient-reported outcome measure (PROM) for hand/upper extremity (UE) pathology and treatment. Here, we conduct a pilot study utilising data collected as a participating site for the Phase II HAND-Q Pilot Multicenter International Validation Study. We hypothesised that self-reported hand functionality, symptom/disease severity, hand appearance, emotional dissatisfaction and treatment satisfaction would be worse in patients who perceived their disease severity to be more severe but would not differ between patients based on prior surgical history. Methods: Patients were prospectively enrolled for HAND-Q participation from September 2018 to August 2019. Patients were included in this analysis if they responded to the following scales of HAND-Q: Hand Functionality Satisfaction, Symptom Severity, Hand Appearance Satisfaction, Emotional Dissatisfaction and Treatment Satisfaction. Composite scores (CS) were created for each section. Surgical versus non-surgical CS and mild versus moderate/severe CS were compared with t- tests. Bi-variate comparisons of responses were performed between surgical and non-surgical groups, and between mild and moderate/severe groups. Results: HAND-Q individual question analysis revealed significant differences in functionality and symptom severity for patients with prior surgery ( p < 0.047). CS analysis confirmed greater overall impairment in surgical patients, but no overall impact on symptom severity. Regarding disease severity HAND-Q individual question analysis, moderate/severe patients reported worse outcomes for specific aesthetic qualities and symptoms for almost all items ( p < 0.05). CS analysis revealed significantly worse overall hand appearance satisfaction, hand functionality, emotional satisfaction and symptom severity for patients with moderate/severe hand conditions. Conclusions: HAND-Q revealed worsened outcomes for UE patients with self-reported moderate/severe conditions or previous surgical history. Understanding how previous surgery and disease severity may impact clinical outcomes is important for crafting appropriate treatment. Level of Evidence: Level II (Prognostic Study).

Using the hand questionnaire (HAND-Q) patient-reported outcome measure, the effects of upper extremity surgery on patients' perception of their sex life were explored. The hand is a uniquely sexual organ, and we hypothesized that self-reported measures of disease severity, quality of life, and emotional impact would correlate with sexual dissatisfaction among patients receiving treatment for hand/upper extremity conditions., Methods: Patients were prospectively enrolled for hand questionnaire participation. Patients with valid responses to the following questions were included: functionality, hand appearance satisfaction, symptom severity, emotional dissatisfaction, sexual dissatisfaction, and treatment satisfaction. Composite scores were created and scored. Sexual dissatisfaction composite scores were compared through Spearman correlation coefficient analysis to quality of life, emotional dissatisfaction, hand appearance, symptom severity, and hand functionality., Results: High levels of diminished quality of life correlated with sexual dissatisfaction (r s = 0.748, P < 0.001). Increased emotional dissatisfaction correlated with sexual dissatisfaction (r s = 0.827, P < 0.001). Increased satisfaction with hand appearance negatively correlated with sexual dissatisfaction (r s = -0.648, P = 0.001). Increased levels of dissatisfaction with hand functionality correlated with sexual dissatisfaction (r s = 0.526, P = 0.005)., Conclusions: The correlation between sex life and quality of life may allow surgeons to improve patient satisfaction when treating hand/upper extremity issues. The relationship between sex life and emotional dissatisfaction emphasizes the impact that sexual dissatisfaction has on patients' lives. Evaluating the relationship between hand appearance and sexual dissatisfaction may indicate that patient self-perception of hand attractiveness plays a role in sex life., (Copyright © 2022 The Authors.

Purpose: Elbow flexion is one of the most important functions to restore following brachial plexus damage. The authors sought to systematically review available evidence to summarize outcomes of free gracilis and non-free muscle transfers in restoring elbow flexion., Methods: MEDLINE, EMBASE, and Cochrane were searched to identify articles reporting on elbow flexion reanimation in terms of transfer failure rates, strengths, range of motion (ROM), and/or Disabilities of the Arm, Shoulder and Hand (DASH) scores. A systematic review was chosen to select studies and reported according to PRISMA guidelines., Results: Forty-six studies met the inclusion criteria for this study. A total of 432 cases were gracilis free-flap muscle transfers (FFMT), and 982 cases were non-free muscle transfers. FFMT were shown to have higher Medical Research Council (MRC) strength scores than non-free muscle transfer groups. However, 42 studies, totaling 1,266 cases, were useful in evaluating graft failure, showing failure (MRC<3) in 77/419 (∼18.4%) of gracilis free-flap transfers and 215/847 (∼25.4%) of non-free muscle transfers. Sixteen articles, 285 cases, were useful to evaluate ROMs (total range: 0-140°), and eight articles, 215 cases, provided DASH scores (total range: 8-90.8)., Conclusions: Of patients who underwent gracilis FFMT procedures, higher mean strength scores and lower failure rates were observed when compared with non-free muscle transfers. Articles reporting non-free muscle transfer procedures (pectoralis, pedicled, Steindler, vascularized ulnar nerve grafts, Oberlin, single/double nerve transfers) provided comprehensive insight into outcomes and indicated that they may result in pooerer poorer DASH scores and ROM., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest directly or indirectly related to the work presented herein.

Enteric duplication cysts are rare congenital anomalies defined by the location along the gastrointestinal tract from which they communicate as well as the epithelial lining they contain. Enteric duplication cysts in communication with the pancreas are an even rarer subset that are often difficult to diagnose due to nonspecific presenting symptoms. In a pediatric patient with a history of recurrent pancreatitis episodes, a pancreatic duplication should be on the differential. High clinical suspicion and specific imaging characteristics can aid in the diagnosis. The management of pancreatic duplication cysts requires surgical excision or drainage procedures to alleviate symptoms and prevent associated complications such as recurrent pancreatitis, bleeding, bowel obstruction, or malignancy. Here we present a case of a gastric duplication cyst in communication with an accessory pancreatic lobe with special focus on the preoperative workup, intraoperative findings, and histopathologic examination.

Background: Increased body mass may predispose children to a greater risk for radial head subluxation (RHS). Recent studies in the literature have reported a plateau in obesity prevalence among infants and toddlers. This study sought to examine recent epidemiological trends in RHS incidence from 2004 to 2018 using the National Electronic Injury Surveillance System database to determine how obesity patterns may affect RHS incidence., Methods: The National Electronic Injury Surveillance System (NEISS) database was queried for patients 6 years of age or younger presenting with radial head subluxation between January 1, 2004 and December 31, 2018. Patient demographics, mechanisms of injury, and location of injury were recorded., Results: An estimated total 253,578 children 6 years or younger were treated for RHS with 14,204 (95% CI = 8124-20,284) in 2004 to 21,408 (95% CI = 12,882-29,934) in 2018. The overall annual rate of RHS per 10,000 children ≤ 6 years was 6.03 (95% CI = 4.85-7.58). The annual rate of RHS per 10,000 children ≤ 6 years increased (m = 0.200, ß = 0.802, p < 0.001) from 5.18 (95% CI 2.96-7.39) in 2004 to 7.69 (95% CI = 4.63-10.75) in 2018. The most common mechanism associated with RHS was falls (39.4%) with 103,466 (95% CI 74,806-132,125) cases. Pulls accounted for the second most common mechanism of injury, accounting for 90,146 (95% CI 68,274-112,018) cases or 36.2%. Yearly RHS incidence was compared to obesity prevalence for ages 2-5 children provided by the National Health and Nutritional Examination Survey (NHANES) surveys. Changes in obesity prevalence may visually reflect RHS incidence trends, but no causality between obesity prevalence and RHS incidence could be confirmed., Conclusion: This study corroborated previous findings that falls and arm pulling contribute to the vast majority of RHS cases. The nonsignificant rise in RHS cases may reflect a possible plateau in obesity prevalence of children aged 2-5 years in recent years., Level of Evidence: III., (© 2021.

As surgical management of carpal tunnel release (CTR) becomes ever more common, extensive research has emerged to optimize the contextualization of this procedure. In particular, CTR under the wide-awake, local-anesthesia, no-tourniquet (WALANT) technique has emerged as a cost-effective, safe, and straightforward option for the millions who undergo this procedure worldwide. CTR under WALANT is associated with considerable cost savings and workflow efficiencies; it can be safely and effectively executed in an outpatient clinic under field sterility with less use of resources and production of waste, and it has consistently demonstrated standard or better post-operative pain control and satisfaction among patients. In this review of the literature, we describe the current findings on CTR using the WALANT technique.

» Radial polydactyly is one of the most common congenital anomalies of the hand, with an incidence of 0.08 to 1.40 per 1,000 live births; it requires surgical treatment early in life.» Polydactyly occurs during weeks 5, 6, 7, and 8 of embryogenesis, principally due to misregulation of the sonic hedgehog protein within the developing limb bud.» The Flatt classification system of preaxial polydactyly (types I to VII), as published by Wassel, categorizes preaxial polydactyly based on osseous abnormalities, but it has substantial limitations.» For improved function and appearance, preaxial polydactyly ideally requires surgical intervention at an early age (between 1 and 2 years of age) before the development of fine motor skills., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSREV/A831)., (Copyright © 2022 by The Journal of Bone and Joint Surgery, Incorporated.)

Background: The use of minor field sterility in hand/upper extremity cases has been shown to improve workflow efficiency while maintaining patient safety. As this finding has been limited to specific procedures, we investigated the safety of performing a wide array of hand/upper extremity procedures outside the main operating room using minimal field sterility with Wide-Awake Local Anaesthesia No Tourniquet (WALANT) anaesthesia by evaluating superficial and deep infection rates across a diverse series of cases., Methods: This study was a case series conducted between October 2017 and June 2020. Of all, 217 patients underwent hand/upper extremity procedures performed in a minor procedure room via WALANT technique with field sterility. Primary outcome measures include superficial and deep surgical site infections within 14 days post-surgery., Results: Of all, 217 patients were included in this study; 265 consecutive hand/upper extremity operations were performed by a single surgeon, with notable case diversity. The majority of patients (n = 215, 99.1%) did not report or present with signs of infection before or after their operation. We report 0% 14-day and 0.37% 30-day surgical site infection rates for such hand/upper extremity procedures performed in a minor procedure room with field sterility., Conclusion: Hand/upper extremity procedures performed via WALANT technique with field sterility in a minor procedure room are associated with low surgical site infection rates. These rates are comparable to surgical site infection rates for similar surgeries performed in main operating rooms with standard sterilization procedures. Thus, the implementation of this technique may allow for improved workflow efficiency and reduced waste, all while maintaining patient safety., Competing Interests: Declaration of Conflicting Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Wide-awake local anesthesia no-tourniquet (WALANT) surgery is an attractive option for hand surgeons, particularly during resource-scarce periods, as it eliminates dependence on main operating rooms or hospital-based procedures. The limited prepping or draping used for WALANT field sterility is as effective, if not more effective, than standard sterile prepping or draping. Patient anxiety surrounding WALANT surgery is similar to or less than that of general or local anesthesia with or without tourniquet. Patients use the same or lower amounts of postoperative narcotics after WALANT as compared to after the other anesthetic methods. Wide-awake local anesthesia no-tourniquet surgery saves significant costs for the same surgeries when performed under general or local anesthesia with or without tourniquet. There are very few complications associated with the WALANT method of anesthesia; rare case reports include vasovagal syncope and cardiac arrhythmia due to inadvertent intravascular injection of epinephrine., (© 2022 The Authors.)

Purpose: The purpose of this bibliometric study was to identify and analyze the most cited publications on acute distal biceps repair., Methods: Using the Clarivate Analytics Web of Science database, we searched for the top 50 most cited publications on acute distal biceps repair and analyzed them based on various metrics., Results: The top 50 publications were cited a total of 3171 times and approximately 151 times per year. However, although the literature on the topic is quite extensive, most publications only contain low-level evidence. In fact, 74% of the 50 most cited publications on the topic contain either level IV or V evidence., Conclusion: This study, through bibliometric analysis, demonstrates that the most often cited studies about acute distal biceps tendon repair are low level of evidence designs. This common injury and study design are ripe for larger randomized or prospective cohort studies., (© 2021.

Purpose: Both-bone forearm fractures in the adult population frequently and usually necessitate an operative reduction. The purpose of this study was to identify the 50 most cited publications regarding both-bone ORIF and evaluates their level of evidence to help guide the best treatment and management practices, as well as gauge the current level of inquiry into this topic., Methods: The Clarivate Analytics Web of Knowledge Database was queried. The top 50 most cited articles identified as relevant were analyzed. Aggregate citation counts, citation density, type of study, and level of evidence were documented for each of the 50 articles. Abstracts from the last decade of prominent orthopaedic meetings were analyzed to determine the current level of inquiry into this area., Results: The initial search yielded 408 results. There were 27 articles published before 2000 and 23 after. The total summation of citations for the top 50 articles totaled 2062. Each study was classified according to its study design and level of evidence. The most common was case series (34). Level IV studies were most numerous (34). Since 2010, the subject of both-bone forearm fracture ORIF was presented 8 times at prominent orthopaedic conferences., Conclusion: Our work demonstrated 54% of top-50 studies are pre-2000 and the majority are Level IV evidence. Additionally, despite the established treatment, there is active inquiry into this topic. Higher quality research can be helpful to validify treatment and management options., (© 2021.

Purpose: Citation analysis has been used to determine the impact of an article in a medical specialty. The purpose of this study was to identify the 50 most cited articles on olecranon fracture outcomes, indications, techniques, procedural descriptions, and complications and analyse their characteristics., Methods: The Web of Science database was used to search for publications related to olecranon fractures. The top 50 most cited articles that met the inclusion criteria were recorded and reviewed in terms of journal and year of publication, country of origin, type of study, and level of evidence., Results: The top 50 articles were cited a total of 2165 times and the year of publication ranged from 1957 to 2014. Of the 50 articles identified, 43 were case series correlating with a Level IV evidence designation. The top 50 articles were published in 20 different medical journals and originated from 18 different countries., Conclusion: The majority of the articles analysed were uncontrolled case series that reported outcomes and complications surrounding the operative treatment of olecranon fractures. The top 50 most influential articles pertaining to olecranon fractures provides physicians and residency programs with a high-yield list of publications to reference on the topic., (© 2021.

Purpose: To describe challenges in the management of prophylaxis against infections for patients receiving medicinal leech therapy given changes in antimicrobial resistance patterns in the normal flora of leeches., Summary: This article presents a patient case of reconstructive surgery complicated by infection associated with the use of medicinal leeches, as well as a discussion of prophylaxis in medicinal leech therapy, focusing on considerations for choosing a prophylactic agent., Conclusion: Our case report highlights resistance changes in Aeromonas isolates associated with medicinal leeches and the potential for complications if isolates resistant to chosen prophylactic agents arise. When administering antimicrobial prophylaxis in patients receiving medicinal leech therapy, clinicians should be familiar with the susceptibilities of Aeromonas species but also conscious of evolving antimicrobial resistance given the extent of the consequences of infected surgical grafts., (© American Society of Health-System Pharmacists 2021.

Background: Favorable rates of meaningful recovery (≥M3/S3) of processed nerve allografts (PNAs) for mixed and motor nerve injuries have been reported, but there are few reports of patients having complete PNA failure (M0/S0). The purpose of this study was to describe the outcomes, including rate of complete failures, in a case series of patients who underwent PNA for peripheral mixed nerve reconstructions., Methods: A retrospective review of outcomes between May 2018 to September 2020 was performed. Consecutive patients who underwent nerve reconstruction (>15 mm) with PNA for a peripheral mixed nerve injury of the upper or lower extremity were eligible. Those who returned to clinic for a 10-month postoperative visit were included in this study. The primary outcome was whether the patient was defined as having a complete failure (M0/S0)., Results: A total of 22 patients underwent a PNA during the time period; 14 patients participated in follow-up and were included (average age: 34.7 years) with a mean follow-up of 11.9 months. The average gap length was 46.4 mm (range 15-110 mm). At their 10-month postoperative visit, no patients had any motor or sensory improvement; all patients were deemed as having complete failure. Four patients underwent or were planned for subsequent revision surgery., Conclusions: In this study, we demonstrated a high number of complete failures, with all 14 included patients sustaining a complete failure (100% failure rate) at a minimum 10-month follow-up visit. Failure in this case series was not observed to affect one nerve type, location, or be related to preoperative injury size., Competing Interests: Disclosure: Dr. Steven Koehler is a committee member of the American Society for Surgery of the Hand (ASSH), a paid consultant and speaker for Integra LifeSciences, Inc, a paid consultant for Tissium, Inc., a stockholder and member of the medical advisory board for Reactiv, Inc., a member of the advisory board for Androes, LLC, and a speaker for TriMed, Inc.

Pediatric hemodialysis access is a demanding field. Procedures are infrequent, technically challenging, and associated with high complication and failure rates. Each procedure affects subsequent access and transplants sites. The choice is made easier and outcomes improved when access decisions are made by a multidisciplinary, pediatric, hemodialysis access team.

Background: The purpose of this systematic review was to (1) define the cumulative humerus fracture rate after BT and (2) compare how often fracture rate was reported compared to other complications., Methods: A systematic review was performed using the PRISMA guidelines., Results: 39 studies reported complications and 30 reported no complications. Of the 39 studies that reported complications, 5 studies reported fracture after BT (n = 669, cumulative incidence of 0.53%). The overall non-fracture complication rate was 12.9%., Discussion: Due to the relatively high incidence of fracture, surgeons should ensure that this complication is disclosed to patients undergoing BT., Competing Interests: SMK is a committee member of the American Society for Surgery of the Hand (ASSH), a paid consultant and speaker for Integra LifeSciences, Inc, a paid consultant for Tissium, Inc., a stockholder and member of the medical advisory board for Reactiv, Inc., a member of the advisory board for Androes, LLC, and a speaker for TriMed, Inc.

Background: Collagen nerve wraps (CNWs) theoretically allow for improved nerve gliding and decreased perineural scarring, and create a secluded environment to allow for nerve myelination and axonal healing. The goal of this study was to investigate the effect of CNWs on nerve gliding as assessed by pull-out strength and nerve changes in a rabbit model of peripheral neuropathy., Methods: Ten New Zealand rabbits were included. Sham surgery (control) was performed on left hindlimbs. To simulate compressive neuropathy, right sciatic nerves were freed of the mesoneurium, and the epineurium was sutured to the wound bed. Five rabbits were euthanized at 6 weeks [scarred nerve (SN); n = 5]. Neurolysis with CNW was performed in the remaining rabbits at 6 weeks (CNW; n = 5), which were euthanized at 22 weeks. Outcomes included peak pull-out force and histopathological markers of nerve recovery (axonal and Schwann cell counts)., Results: The CNW group demonstrated significantly higher pull-out forces compared with the CNW sham control group (median: 4.40N versus 0.37N, P = 0.043) and a trend toward greater peak pull-out forces compared with the SN group (median: 4.40N versus 2.01N, P = 0.076). The CNW group had a significantly higher median Schwann cell density compared with the CNW control group (CNW: 1.30 × 10 -3 cells/μm 2 versus CNW control: 7.781 × 10 -4 cells/μm 2 , P = 0.0431) and SN group (CNW: 1.30 × 10 -3 cells/μm 2 versus SN: 7.31 × 10 -4 cells/μm 2 , P = 0.009). No significant difference in axonal density was observed between groups., Conclusion: Our findings suggest using a CNW does not improve nerve gliding, but may instead play a role in recruiting and/or supporting Schwann cells and their proliferation., Competing Interests: Disclosure: Dr. Koehler is a committee member of the American Society for Surgery of the Hand (ASSH), a paid consultant and speaker for Integra LifeSciences, Inc, a paid consultant for Tissium, Inc., a stockholder and member of the medical advisory board for Reactiv, Inc., and a speaker for TriMed, Inc.

This study evaluates current guidelines for patients receiving local anesthesia, set forth by the Association of Perioperative Nurses (AORN), within the context of hand surgery. The study reviewed 217 patients and 265 operations performed under wide-awake local anesthesia no tourniquet (WALANT) technique in an outpatient procedure room with minor field sterility. Only the surgeon, one resident, and one circulating nurse were present. All surgical complications were documented, including any infection at postoperative follow-ups. One female patient developed a deep surgical site infection (SSI) following repair of her flexor digitorum superficialis and flexor digitorum profundus, which resolved after irrigation/debridement. We report 0% intraprocedural complication, 0% superficial SSI, and 0.37% deep SSI (n = 1) incidence across this cohort. Most institutions require two nurses present for local anesthesia, but our low complication and infection incidence suggest a single circulating nurse present during WALANT hand surgeries may improve nurse staffing, drive greater turnover efficiency, and reduce costs.

Purpose: This study identifies the most impactful papers on scapholunate reconstruction and provides a quantitative assessment of the impact of these papers in order to inform future clinical practice, education, and research of this condition., Methods: The Scopus database was used in May 2020 to identify the 50 most cited clinical articles pertaining solely to chronic scapholunate reconstruction. Citation number and density, publication variables, and Altmetric Attention Scores (AASs) were collected and analyzed., Results: The top 50 articles on chronic scapholunate reconstruction produced 1,868 total citations, with an average of 37.36 ± 39.90 citations per article (range 7-196) and an average citation density of 2.44 ± 2.27. US-based publications (n = 20) and articles published in Journal of Hand Surgery (n = 24) were associated with significantly higher citation number and density (p < 0.01 - p = 0.018). In addition, sample size was positively correlated with citation density (rho = 0.312, p = 0.029). Fourteen articles were associated with an AAS (mean score = 4.07 ± 4.70). There was no significant association between AAS and citation number or density, but AAS did significantly predict citation density (coefficient = 0.378, 95% CI: [0.013-0.741], p = 0.043)., Conclusion: Numerous factors, such as journal of publication, location, and sample size, were significantly associated with citation number and/or citation density. Interestingly, AAS was predictive of, but not directly correlated with citation density, suggesting that the impact of scapholunate literature may not be adequately captured with a citation analysis., (© 2021.

Background  The scapholunate interosseous ligament (SLIL) couples the scaphoid and lunate, preventing motion and instability. Prior studies suggest that damage to the SLIL may significantly alter contact pressures of the radiocarpal joint. Questions/Purposes  The purpose of this study was to investigate the contact pressure and contact area in the scaphoid and lunate fossae of the radius prior to and after sectioning the SLIL. Methods  Ten cadaveric forearms were dissected distal to 1-cm proximal to the radiocarpal joint and a Tekscan sensor was placed in the radiocarpal joint. The potted specimen was mounted and an axial load of 200 N was applied over 60 seconds. Results  Sectioning of the SLIL did neither significantly alter mean contact pressure at the lunate fossa ( p  = 0.842) nor scaphoid fossa ( p  = 0.760). Peak pressures were similar between both states at the lunate and scaphoid fossae ( p  = 0.301-0.959). Contact areas were similar at the lunate fossa ( p  = 0.508) but trended toward an increase in the SLIL sectioned state in the scaphoid fossa ( p  = 0.055). No significant differences in the distribution of contact pressure ( p  = 0.799), peak pressure ( p  = 0.445), and contact area ( p  = 0.203) between the scaphoid and lunate fossae after sectioning were observed. Conclusion  Complete sectioning of the SLIL in isolation may not be sufficient to alter the contact pressures of the wrist. Clinical Relevance  Injury to the secondary stabilizers of the SL joint, in addition to complete sectioning of the SLIL, may be needed to induce altered biomechanics and ultimately degenerative changes of the radiocarpal joint., Competing Interests: Conflict of Interest S.M.K. is a committee member of the American Society for Surgery of the Hand (ASSH), a paid consultant and speaker for Integra Life Sciences, Inc., a paid consultant for Tissium, Inc., a stockholder and member of the medical advisory board for Reactiv, Inc., amember of the advisory board for Androes, LLC, and a speaker for TriMed, Inc.

Background: Currently, opioids are the standard of care for postoperative pain management. Avoiding unnecessary opioid exposure in patients is of current interest because of widespread abuse., Methods: This is a prospective cohort study in which wide-awake, local anesthesia, no-tourniquet (WALANT) technique was used for 94 hand/upper extremity surgical patients and compared to patient cohorts undergoing similar procedures under monitored anesthesia care. Patients were not prescribed opioids postoperatively but were instead directed to use over-the-counter pain relievers. Pain scores on a visual analogue scale were collected from patients preoperatively, and on postoperative days 1 and 14. WALANT visual analogue scale scores were compared to those of the two patient cohorts who either did or did not receive postoperative opioids after undergoing similar procedures under monitored anesthesia care. Electronic medical records and New York State's prescription monitoring program, Internet System for Tracking Over-Prescribing, were used to assess prescription opioid-seeking. Information on sex, age, comorbidity burden, previous opioid exposure, and insurance coverage was also collected., Results: Decreased pain was reported by WALANT patients 14 days postoperatively compared to preoperatively and 1 day postoperatively, with a total group mean pain score of 0.37. This is lower than mean scores of monitored anesthesia care patients with and without postoperative opioids. Only two WALANT patients (2.1 percent) sought opioid prescriptions from outside providers. There was little evidence suggesting factors including sex, age, comorbidity burden, previous opioid exposure, or insurance status alter these results., Conclusion: WALANT may be a beneficial technique hand surgeons may adopt to mitigate use of postoperative opioids and reduce risk of abuse in patients., Clinical Question/level of Evidence: Therapeutic, II., (Copyright © 2021 by the American Society of Plastic Surgeons.)

Introduction: Between 2008 and 2017, the American Pyrotechnics Association reported a 41% increase in revenue from firework sales, with 2017 showing $885 million US dollars in consumer sales. We sought to evaluate the epidemiology of firework-related upper extremity injuries during this 10-year period, hypothesizing that hand/upper extremity injuries from fireworks were increasing in the United States., Methods: Observational epidemiologic assessment of a weighted cohort of patients via the National Electronic Injury Surveillance System from 2008 to 2017. The National Electronic Injury Surveillance System provides a nationwide probability sample of injuries related to consumer products based on emergency department visits collected from a cohort of about 100 US hospitals., Results: A total of 1,079 patients representing an estimated 41,195 firework-related upper extremity injuries presented to US emergency departments from 2008 to 2017. The number of injuries increased significantly from 2,576 in 2008 to 5,101 in 2017 (R2 = 0.85, R = 0.92, P < 0.001). A Spearman rank-order correlation determined that there was a strong, positive correlation between the increase in firework sales and the increase in injuries (rs = 0.939, P < 0.01). The overwhelming majority of firework-related injuries were seen in males (77%) aged 11 to 29 years (48%). The hand and fingers accounted for 85.8% of injuries, with the thumb being the most commonly injured body part (51.3%). Burns were the most common injury across all body sites except the wrist, where fractures were most common., Conclusion: Ten-year firework-related upper extremity injuries increased, corresponding to increased consumer sales across the same period. This study provides previously absent population-level data to provide a framework for discussion among policy makers and physicians alike in an attempt to mitigate the use of fireworks and their associated upper extremity injuries., Level of Evidence: Level III., (Copyright © 2020 by the American Academy of Orthopaedic Surgeons.)

Introduction: Kirschner wires (K-wires) have been shown to effectively stabilize fractures of the hand and wrist, but are associated with high infection rates, which may limit its use. Previous literature has attributed the risk of infection to many different aspects of a fixation technique. However, we introduce an approach to percutaneous K-wire pinning to mitigate the risk of infection., Methods: Patients undergoing K-wire fixation procedures of the hand and wrist were retrospectively queried. All cases were performed under the same principles of our technique. None of the K-wires were buried, nor bent and were covered with betadine-soaked alcohol pads as pin site dressings. Pins were removed in an outpatient procedure room up to 12 weeks postoperatively and were then assessed for signs of superficial or deep infection., Results: 90 patients were included in this study across a variety of K-wire fixation operations in the hand and wrist. No patients presented with any signs of infection or other complications necessitating postoperative antibiotics, early pin removal, or reoperation., Discussion/conclusion: The specific guidelines of our technique resulted in no cases of pin site infection, despite a largely underserved patient population. Our low incidence of infection was maintained without the use of prophylactic antibiotics and in patients with long periods of fixation. While the high infection rates in previous literature have often been associated with wires left exposed, the principles of our technique allow for K-wire fixations to be performed percutaneously without burying the wires. This may allow for improved cost and time efficiency, without compromising patient safety., Competing Interests: Declaration of Competing Interest Dr. Steven Koehler is a committee member of the American Society for Surgery of the Hand (ASSH), a paid consultant and speaker for Integra LifeSciences, Inc, a paid consultant for Tissium, Inc., a stockholder and member of the medical advisory board for Reactiv, Inc., a member of the advisory board for Androes, LLC, and a speaker for TriMed, Inc.
