Medicaid payer status has been shown to affect risk-adjusted patient outcomes and health care utilization across multiple medical specialties and orthopedic procedures. However, there is a paucity of data regarding the impact of Medicaid payer status on 90-day morbidity and resource utilization following primary shoulder arthroplasty (reverse total shoulder arthroplasty [rTSA], anatomic total shoulder arthroplasty [aTSA], and hemiarthroplasty [HA]). The purpose of this study was to examine 90-day readmission and reoperation rates, hospital length of stay (LOS), and direct cost following primary shoulder arthroplasty in the Medicaid population.The National Readmission Database was queried for all patients undergoing primary aTSA, rTSA, and HA from 2011 to 2016. Medicaid or non-Medicaid payer status was determined. Patient demographic characteristics and comorbidities, along with 90-day readmission, 90-day reoperation, LOS, and inflation-adjusted cost, were queried. Propensity score matching was used to control for baseline differences in cohorts that could be acting as confounders in the exposure-outcome relationship. This was achieved with 1-to-1 propensity score matching between Medicaid and non-Medicaid patients. Odds ratios (ORs) and 95% confidence intervals (CIs) for 90-day readmission and reoperation rates were calculated, and a comparison of LOS and cost was performed between the propensity score-matched cohorts.A total of 4667 Medicaid and 161,147 non-Medicaid patients were identified from the 2011-2016 National Readmission Databases. Propensity score analysis was performed, and 4637 Medicaid patients were matched to 4637 non-Medicaid patients; each group comprised 1504 rTSAs (32.4%), 1934 aTSAs (41.7%), and 1199 HAs (25.9%). Patients with Medicaid payer status yielded significant increases in the 90-day all-cause readmission rate of 11.6% vs. 9.3% (P .001; OR, 1.28 [95% CI, 1.12-1.46]), 90-day shoulder-related readmission rate of 3.3% vs. 2.3% (P = .004; OR, 1.44 [95% CI, 1.12-1.85]), and 90-day reoperation rate of 2.0% vs. 1.3% (P = .008; OR, 1.54 [95% CI, 1.12-1.94]). Furthermore, there was an increased risk of an extended LOS (ie, LOS2 days) (28.4% vs. 25.7%; P = .004; OR, 1.14 [95% CI, 1.04-1.25]) along with increased direct cost (median, $17,612 vs. $16,775; P .001).This study demonstrates that Medicaid payer status is independently associated with increased 90-day readmission and reoperation rates, LOS, and direct cost following primary shoulder arthroplasty. Providers may have a disincentive to treat patient populations who require increased resource utilization following surgery. Risk adjustment models accounting for Medicaid payer status will be necessary to ensure good access to care for this patient population by avoiding penalties for physicians and hospital systems.

COVID-19 triggered disruption in the conventional care pathways for many orthopedic procedures. The current study aims to quantify the impact of the COVID-19 pandemic on shoulder arthroplasty hospital surgical volume, trends in surgical case distribution, length of hospitalization, posthospital disposition, and 30-day readmission rates.This study queried all Medicare (100% sample) fee-for-service beneficiaries who underwent a shoulder arthroplasty procedure (Diagnosis-Related Group code 483, Current Procedural Terminology code 23472) from January 1, 2019, to December 18, 2020. Fracture cases were separated from nonfracture cases, which were further subdivided into anatomic or reverse arthroplasty. Volume per 1000 Medicare beneficiaries was calculated from April to December 2020 and compared to the same months in 2019. Length of stay (LOS), discharged-home rate, and 30-day readmission for the same period were obtained. The yearly difference adjusted for age, sex, race (white vs. nonwhite), Centers for MedicareMedicaid Services Hierarchical Condition Category risk score, month fixed effects, and Core-Based Statistical Area fixed effects, with standard errors clustered at the provider level, was calculated using a multivariate analysis (P .05).A total of 49,412 and 41,554 total shoulder arthroplasty (TSA) cases were observed April through December for 2019 and 2020, respectively. There was an overall decrease in shoulder arthroplasty volume per 1000 Medicare beneficiaries by 14% (19% reduction in anatomic TSA, 13% reduction in reverse shoulder arthroplasty, and 3% reduction in fracture cases). LOS for all shoulder arthroplasty cases decreased by 16% (-0.27 days, P .001) when adjusted for confounders. There was a 5% increase in the discharged-home rate (88.0% to 92.7%, P .001), which was most prominent in fracture cases, with a 20% increase in discharged-home cases (65.0% to 73.4%, P .001). There was no significant change in 30-day hospital readmission rates overall (P = .20) or when broken down by individual procedures.There was an overall decrease in shoulder arthroplasty volume per 1000 Medicare beneficiaries by 14% during the COVID-19 pandemic. A decrease in LOS and increase in the discharged-home rates was also observed with no significant change in 30-day hospital readmission, indicating that a shift toward an outpatient surgical model can be performed safely and efficiently and has the potential to provide value.

Perioperative glucocorticoids have been effectively used as a pain management regimen for reducing pain after hand surgery. We hypothesize that a methylprednisolone taper (MPT) course following surgery will reduce pain and opioid consumption in the early postoperative period.This study was a randomized controlled trial of patients undergoing surgical fixation for distal radius fracture. Before surgery, patients were randomly assigned to receive preoperative dexamethasone only or preoperative dexamethasone followed by a 6-day oral MPT. Patient pain and opioid consumption data were collected for 7 days after surgery using a patient-reported pain journal.Our study consisted of 56 patients enrolled from November 2018 to March 2020. Twenty-eight patients each were assigned to the control and treatment groups. Demographic characteristics such as age, body mass index, the dominant side affected, smoking status, diabetes status, and current narcotic use were similar between the control and treatment groups. With a noticeable, significant reduction starting on postoperative day 2, patients who received an MPT course consumed substantially less opioids during the first 7 days (7.8 ± 7.2 pills compared with 15.5 ± 11.5 pills, a 50% reduction). These patients also consumed significantly fewer oral morphine equivalents than the control group (81.2 vs 41.2). A significant difference in the pain visual analog scale scores between the 2 groups was noted starting on postoperative day 2, with 48% of the treatment group reporting no pain by postoperative day 6. No adverse events, including infection or complications of wound or bone healing, were seen in either group.There was an early improvement in pain and reduction in early opioid consumption with a 6-day MPT following surgical fixation for distal radius fracture. With no increased risk of adverse events in our sample, MPT may be a safe and effective way to reduce postoperative pain.Therapeutic II.

Supplementary Data from Synergistic Antitumor Effect of the Activated PPARγ and Retinoid Receptors on Human Osteosarcoma

Purpose: Osteosarcoma is the most common primary malignancy of bone. The long-term survival of osteosarcoma patients hinges on our ability to prevent and/or treat recurrent and metastatic lesions. Here, we investigated the activation of peroxisome proliferator-activated receptor γ (PPARγ) and retinoid receptors as a means of differentiation therapy for human osteosarcoma.Experimental Design: We examined the endogenous expression of PPARγ and retinoid receptors in a panel of osteosarcoma cells. Ligands or adenovirus-mediated overexpression of these receptors were tested to inhibit proliferation and induce apoptosis of osteosarcoma cells. Osteosarcoma cells overexpressing the receptors were introduced into an orthotopic tumor model. The effect of these ligands on osteoblastic differentiation was further investigated.Results: Endogenous expression of PPARγ and isotypes of retinoic acid receptor (RAR) and retinoid X receptor (RXR) is detected in most osteosarcoma cells. Troglitazone, 9-cis retinoic acid (RA), and all-trans RA, as well as overexpression of PPARγ, RARα, and RXRα, inhibit osteosarcoma cell proliferation and induce apoptosis. A synergistic inhibitory effect on osteosarcoma cell proliferation is observed between troglitazone and retinoids, as well as with the overexpression pairs of PPARγ/RARα, or PPARγ/RXRα. Overexpression of PPARγ, RARα, RXRα, or in combinations inhibits osteosarcoma tumor growth and cell proliferation in vivo. Retinoids (and to a lesser extent, troglitazone) are shown to promote osteogenic differentiation of osteosarcoma cells and mesenchymal stem cells.Conclusions: Activation of PPARγ, RARα, and RXRα may act synergistically on inhibiting osteosarcoma cell proliferation and tumor growth, which is at least partially mediated by promoting osteoblastic differentiation of osteosarcoma cells.

Endoprosthetic or allograft reconstruction are the preferred reconstruction techniques for proximal humeral bone tumors. Failure of these reconstructions may occur, but historically revision is performed rarely due to the lack of reliable options. Reverse shoulder arthroplasty with an allograft prosthetic composite (rAPC) may provide a revision option. The purpose of the current study was to evaluate our institutional outcome of these procedures.Eleven (6 male, 5 female) patients (mean age 51 ± 17 years) underwent revision of a failed oncologic reconstruction of the proximal humerus utilizing a rAPC. The most common indication for revision was subluxation (n = 6) and the most common previous implant was an endoprosthesis (n = 5).Revision resulted in improvements in shoulder elevation (39° vs. 62°, p = 0.02), external rotation (13° vs. 25°, p = 0.04), American Shoulder and Elbow Surgeons score (39 vs. 58, p = 0.004) and Musculoskeletal Tumor Society Scores (51% vs 69%, p = 0.002). There were 2 re-revision procedures performed. One for an allograft fracture and one for allograft resorption and loosening.Revision with a rAPC can effectively restore patient function. Due to the complexity of the cases, we advocate for these procedures to be performed by subspecialty upper extremity surgeons trained in complex revision shoulder arthroplasty.

Dupuytren disease is associated with benign fibroproliferative changes to the palmar fascia of the hand sometimes resulting in progressive contractures of the fingers. The earliest descriptions of these contractures date back to the 18th century. Much has been learned about the condition since the clawing condition was first described; however, optimal treatment still poses significant challenges to modern-day surgeons. It is important to examine the treatment options for Dupuytren disease and highlight the current evidence, techniques, and cost considerations of open fasciectomy, needle aponeurotomy, and recently described minimally invasive treatment.

Neurogenic thoracic outlet syndrome is a challenging condition to diagnose and treat, often precipitated by the triad of repetitive overhead activity, pectoralis minor contracture, and scapular dyskinesia. The resultant protracted scapular posture creates gradual repetitive traction injury of the suprascapular nerve via tethering at the suprascapular notch and decreases the volume of the brachial plexus cords and axillary vessels in the retropectoralis minor space. A stepwise and exhaustive diagnostic protocol is essential to exclude alternate pathologies and confirm the diagnosis of this dynamic pathologic process. Ultrasound-guided injections of local anesthetic or botulinum toxin are a key factor in confirming the diagnosis and prognosticating potential response from surgical release. In patients who fail over 6 months of supervised physical therapy aimed at correcting scapular posture and stretching of the pectoralis minor, arthroscopic surgical release is indicated. We present our diagnostic algorithm and technique for arthroscopic suprascapular neurolysis, pectoralis minor release, brachial plexus neurolysis, and infraclavicular thoracic outlet decompression.

Wrist arthroscopy represents the most recent development in the diagnosis and treatment of Kienböck disease. Through direct visualization of lunate and adjacent carpal articulations, a more accurate diagnosis can be obtained and, ultimately, a more precise treatment decision. Treatments that are based on bypassing, fusing, or excising "nonfunctional" articulations can be done with less morbidity than traditional open techniques by using arthroscopy. Given the minimal capsular and soft tissue scarring, this potentially improves early pain and functional recovery. Although technically demanding, long-term outcomes studies have shown that the benefits of an arthroscopic approach may be worth the learning curve.

Functionally irreparable rotator cuff tears (FIRCTs) present an ongoing challenge to the orthopedic surgeon. The aim of this systematic review was to critically compare the outcomes of three latissimus dorsi tendon transfer (LDT) techniques and two superior capsular reconstruction (SCR) techniques in treatment of FIRCTs. A systematic review of studies evaluating the outcome of FIRCT treatment was performed via a search of four databases in April 2020. Each included study was reviewed in duplicate by two reviewers for evaluation of methodological quality. The treatments analyzed were arthroscopic LDT (aLDT), open LDT Gerber technique (oLDTG), open LDT L’Episcopo technique (oLDTL), SCR with allograft (SCR-Allo), and SCR with autograft (SCR-TFL). Demographics, range of motion, patient-reported outcome measures, radiographic acromiohumeral distance (AHD), treatment failures, and revisions were recorded. Forty-six studies (1287 shoulders) met criteria for inclusion. Twenty-three studies involved open latissimus transfer, with 445 shoulders undergoing oLDTG with mean follow-up of 63.2 months and 60 patients undergoing oLDTL with mean follow-up of 51.8 months. Ten studies (n = 369, F/U 29.2mo) reported on aLDT. Seven studies (n = 253, F/U 16.9mo) concerned SCR-Allo, and six studies (n = 160, F/U 32.mo) reported on SCR-TFL. Range of motion and subjective outcome scores improved in all techniques with no differences across treatments. Both SCR methods provided greater improvement in AHD than open LDT methods (p

Shoulder instability in hypermobile Ehlers-Danlos syndrome can result in lifelong pain and functional disability. Treatment in this population is complicated by the severe degree of instability as well as the underlying abnormalities of the joint connective tissue. Appropriate care for these patients requires a thorough understanding of the natural history of their disease, knowledge of the available treatment options, and certain special considerations. This article reviews the pathoanatomy, recognition, and management of shoulder instability in the patient with hypermobile Ehlers-Danlos syndrome.

Purpose To examine the accuracy, sensitivity, and specificity of a minimally invasive needle arthroscopy device and magnetic resonance imaging (MRI) compared with diagnostic arthroscopy, the gold standard in diagnosing intra-articular shoulder pathologies. Methods This was a prospective, blinded clinical trial over 6 months on 50 patients with shoulder pathology requiring arthroscopy. Patients were eligible if they had an MRI and consented for surgical arthroscopy. Patients were excluded if they didn’t consent. Each underwent a clinical evaluation, MRI, needle arthroscopy, and surgical arthroscopy. Videos and images were blindly reviewed postoperatively. Analysis included sensitivity, specificity, positive predictive value (PPV), negative predictive value, Cohen’s kappa agreement coefficient, and the McNemar test. Results Needle arthroscopy had similar accuracy to MRI in diagnosing intra-articular shoulder pathologies when both were compared with the gold standard of diagnostic arthroscopy. It had high specificities and PPV for certain rotator cuff tears, biceps pathology, and anterior labral tears. When compared with the gold standard, specificity of needle arthroscopy for diagnosing rotator cuff tear and cartilage lesions was 1.00 and 0.97 and 0.72 and 0.86 for MRIs, respectively. Sensitivity of needle arthroscopy for rotator cuff and cartilage lesions was 0.89 and 0.74, respectively, lower than MRI. For most intra-articular pathologies, needle arthroscopy was at least equally accurate to MRI at diagnosing intra-articular shoulder pathologies, with similar or high kappa statistics when correlated with surgical arthroscopic findings. Conclusions Needle arthroscopy is a promising diagnostic modality for intra-articular shoulder pathologies. It had comparable accuracy with MRI for diagnosing articular cartilage, labrum, rotator cuff, and biceps pathology. Across all pathologies, needle arthroscopy had better ability to “rule in” a diagnosis (high specificities and PPV), but slightly worse ability to “rule out” a diagnosis (lower sensitivities and negative predictive value) compared with MRI.

Background Patients with ulnar nerve paralysis note difficulties performing activities of daily living because of weakness of pinch and altered grasp mechanism. This review investigates outcomes of tendon transfers for ulnar nerve paralysis to assist in shared decision-making with patients during preoperative counseling and to inform operative choices. Methods A systematic review was conducted to identify studies reporting outcomes following tendon transfer for ulnar nerve palsy. Studies were screened according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and inclusion and exclusion criteria were applied. Primary outcome measures included postoperative pinch strength and mechanism of grasp. Results A total of 26 studies (687 patients) met criteria for inclusion. After pooled analysis, the flexor digitorum superficialis lasso procedure yielded the highest rate of complete correction of claw deformity (60.6 percent), followed by flexor digitorum superficialis four-tail operation (31.4 percent). The extensor carpi radialis longus four-tail operation yielded the greatest improvement in grip strength (3.8 kg). The extensor carpi radialis brevis four-tail operation resulted in the best open hand assessment and mechanism of closing scores; however, these studies did not objectively evaluate grip strength. The greatest increase in pinch strength was following tendon transfer to adductor pollicis alone. Conclusions Despite the heterogeneous data, if the primary goal is improvement in the appearance of claw deformity, the evidence supports flexor digitorum superficialis lasso transfer. However, if the primary concern is grip strength, the data favor extensor carpi radialis longus four-tail transfer. When pinch strength is functionally limiting, adductorplasty alone is most effective. These data will assist providers in appropriately informing patients of common risks and complications and setting realistic expectations following tendon transfer procedures.

Introduction With the increasing incidence of total shoulder arthroplasty (TSA) being performed worldwide, there is a growing effort to reduce postoperative pain, the consumption of opioids (oral morphine equivalents [OMEs]), and subsequent in hospital length of stay. Although perioperative pain control regimens have been widely studied in patients undergoing TSA, patients continue to consume a significant quantity of opioids after surgery. In the era of an opioid epidemic, novel methods for the improvement of perioperative pain control is of utmost importance. The aim of this quality improvement initiative was to evaluate the effect of liposomal bupivacaine (LB) versus ropivacaine (RP) in interscalene peripheral nerve blockade (IPNB) in patients undergoing TSA. Methods This quality improvement initiative prospectively evaluated a consecutive group of patients undergoing TSA from June 2017 to September 2019. Patients were included if they underwent either an anatomic or reverse shoulder arthroplasty at a single institution by 1 of 2 fellowship trained surgeons. Patients were divided in to 2 temporal cohorts based on the US Food and Drug administration's approval of LB. Patients who received a RPIPNB were in the control group, while those who received a LBIPNB were in the treatment group. Outcome measures studied included average visual analog pain scores (VAS) at 24 and 48 hours in the hospital, OME's, and length of stay. Results A total of 114 patients underwent TSA and met the inclusion criteria to be included in the analysis: 58 received RPIPNB and 56 received LBIPNB. The cohorts did not demonstrate any statistically different attributes (eg, age, sex, dominance, smoking status, psychiatric disorders, diabetes, HTN, or ASA class). Difference in 24 hour and 48 hour VAS pain scores was significantly improved in the LBIPNB group as compared to the RPIPNB group (2.46 vs. 0.72, and 2.02 and −0.41, respectively P Conclusion Despite significantly improved pain scores at 24 hours and 48 hours, patients who received LBIPNB did not demonstrate a statistically significant improvement in LOS or quantity of OME's consumed. The discrepancy between subjective numeric pain scores and objective healthcare metrics is likely multifactorial, and brings to light the difficulty in determining the value of new pain regimens. In lieu of these findings, it is difficult to endorse or reject the use of LBIPNB in TSA. Without further studies demonstrating improved efficacy in reduction of opioid consumption and LOS, given the additional expense of the drug, its continued use remains uncertain.

Carpal tunnel syndrome and ulnar nerve compression at the elbow (e.g., cubital tunnel syndrome) are the most common upper extremity compressive neuropa- thies treated by hand surgeons. The aim of this study was to determine demographic factors and comorbidities that can help predict those patients most likely to undergo concurrent release of both the carpal tunnel and ulnar nerve at the elbow. We hypothesized that certain comorbidities, such as diabetes, would be associated with an increased risk for the necessity of concomitant procedures.Using Truven Marketscan® database, all patients who underwent carpal tunnel release were identified from 2010 to 2017 using Current Procedural Terminology (CPT) codes. Patients were only included if they had continuous enrollment in the database for 12 months preoperatively. Preoperative comorbidities and concurrent procedures were collected us- ing CPT and ICD-9 and 10 codes. Patients who underwent simultaneous carpal tunnel and ulnar nerve at the elbow release on the same day were compared to those patients who underwent carpal tunnel release alone. Additionally, patients who underwent either procedure initially and then went on to have the other procedure at a later date were compared. Univariate analysis and binomial logistic regression were performed to assess the contribution of patient demographics and comorbidities on the necessity of simultaneous release.259,574 patients underwent carpal tunnel release surgery and were included in the study. 24,401 (7.9%) of pa- tients also underwent simultaneous ulnar nerve release at the elbow on the same day. Significant risk factors associated with the need for simultaneous release, were male gender [(Odds Ratio (OR): 2.05, Confidence Interval (CI): 2.00-2.11, p0.001)], chronic pain (OR: 1.78, CI: 1.68-1.87, p0.001), diabetes (OR: 1.29, CI: 1.25-1.33, p0.001), history of al- coholism (OR: 1.23, CI: 1.10-1.38, p0.001), chronic renal disease (OR: 1.26, CI: 1.18-1.34, p0.001), tobacco use (OR: 1.49, CI: 1.42-1.56, p0.001), and patients with congestive heart failure (OR: 1.26, CI: 1.17-1.35, p0.001). Patients with consumer driven health plans and high deductible health plans (HDHP) were 1.5 times more likely to have simultane- ous release compared to those with comprehensive plans (OR: 1.46, CI: 1.37-1.56, p0.001; OR: 1.45, CI: 1.34-1.57, p0.001; respectively). For necessity of subsequent carpal or ulnar nerve release after either primary procedure, patients with a minimum of 3 years enrollment in the database were analyzed. Of the 113,505 patients who underwent initial carpal tunnel release, 1,746 (1.5%) went on to undergo release of the ulnar nerve at the elbow. Of the 12,673 patients who had initial ulnar nerve releases at the elbow, 721 (5.7%) required additional release of the carpal tunnel.Identification of patient demographic factors and comorbidities that can help predict the likelihood of si- multaneous release of both the carpal tunnel and ulnar nerve at the elbow can help direct management of these patients. Combining the two procedures can help save resources, minimize patient burden, and help reduce excess health care utilization.

Background First carpometacarpal (CMC) osteoarthritis or trapeziometacarpal osteoarthritis is a common debilitating hand condition. No one surgical technique has demonstrated superiority in managing this disease. Purpose This study performed a systematic review of arthroscopic techniques for treating first CMC arthritis to assess the effectiveness of different arthroscopic techniques. Methods Grip strength, pinch strength, visual analog scale, the Disability of Arm, Shoulder, and Hand (DASH) score, range of motion (ROM), and complications were recorded. Two subgroup analyses were performed, comparing outcomes of (1) trapeziectomy of any type versus debridement alone and (2) trapeziectomy alone versus interposition versus suspension techniques. Results Preoperative and postoperative scores significantly improved for DASH scores and pain at rest and with activity with variable improvements in ROM. Complications occurred in 13% of cases in publications that reported complications. When comparing studies that utilized techniques with any type of trapeziectomy to debridement alone, only the trapeziectomy subgroup showed significant improvements in pain. When comparing trapeziectomy alone to interposition and suspension techniques, mean DASH scores and pain levels significantly improved in interposition and suspension subgroups. Conclusions The existing literature describes a predominantly female population with Eaton-Littler stage II and III disease. In the subgroup analysis, arthroscopic techniques involving a trapeziectomy seem to be more effective at lowering pain scores compared to techniques involving debridement alone. Likewise, interposition and suspension techniques may show improved outcomes compared to techniques involving trapeziectomy alone. Level of evidence This is a Level III study.

Distal radius fractures (DRFs) are among the most common fractures in the United States. Despite their high incidence, there is no consensus on the optimal type of cast or splint to treat these fractures. The purpose of this systematic review is to evaluate the available literature pertaining to the outcomes for different constructs used to conservatively treat DRFs. A literature search of PubMed, Medline, and Embase was conducted to identify research comparing the outcomes of various immobilization mechanisms. In particular, endpoints included complications (eg, loss of reduction, pain), radiographic outcomes, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. A total of 1655 articles were identified during the literature search, and 22 ultimately fulfilled inclusion criteria. These 22 studies included 1826 conservatively treated DRFs. The different immobilization mechanisms were divided into 8 groupings: above-elbow casts, above-elbow splints, below-elbow casts, below-elbow splints, gutter or spica casts, gutter or spica splints, dorsal-volar splints, and dorsal splints. Qualitative review of the studies determined that below-elbow constructs result in equal or better functional and radiologic outcomes when compared with above-elbow constructs. Meta-analysis demonstrated that a statistically significant difference ( P = .04) existed in the incidence of loss of reduction between the immobilization constructs, although post hoc analysis did not detect significant differences between 2 particular constructs.

Purpose The aims of this systematic review were to examine the use of radiolunate (RL) or radioscapholunate (RSL) arthrodesis as surgical management for patients with advanced radiocarpal arthritis that failed conservative management and to assess postoperative outcomes. Methods We reviewed articles from PubMed, EMBASE, and Web of Science from inception through December 2019. We identified complete manuscripts written in English reporting on RL or RSL arthrodesis for treatment of wrist pathology that included the primary outcomes (pain or grip strength) and at least 2 secondary outcomes (range of motion, patient-reported outcomes, or nonunion). Data pooling was used to calculate weighted averages. Results We identified 2,252 articles and selected 13 for inclusion. Across all studies, RSL arthrodesis was performed for 180 patients (49% female; 45 years old) and RL for 94 (87% female; 50 years old). Both procedures exhibited improvements in pain score and grip strength. Both cohorts demonstrated postoperative changes in flexion-extension arc, flexion, extension, ulnar deviation, supination, and pronation after data pooling. The nonunion rate for RSL was 15% versus 2% for RL, whereas the rate of progression to total wrist arthrodesis for RSL and RL was 4% and 0%, respectively. Conclusions Both RL and RSL arthrodesis can be successfully used to manage debilitating radiocarpal arthritis by affording patients with pain reduction. Each has its own benefits, in which RSL arthrodesis provides a total arc of motion within the functional demands of most activities of daily living, and RL arthrodesis has low rates of nonunion and progression to total wrist arthrodesis. Further research is needed to compare the 2 surgeries directly and prospectively in comparable patient groups. Type of study/level of evidence Therapeutic III.

Purpose To evaluate factors that predict the use of electrodiagnostic testing (EDS) for patients undergoing carpal tunnel release (CTR). Methods In this cohort study, we analyzed 553 patients who underwent primary CTR from 8 practices between July 1, 2019 and December 1, 2019 by 32 surgeons in the Michigan Collaborative Hand Initiative for Quality in Surgery (M-CHIQS). The M-CHIQS is a collaborative initiative aimed at improving quality in hand surgery. Demographic and clinical characteristics were collected, including the 6-item carpal tunnel symptoms scale (CTS-6) scores and EDS timing. Multilevel logistic regression was used to assess practice and surgeon variation in EDS use related to clinical diagnostic criteria. Results Of the 553 patients who underwent CTR during the study period, 461 (83.3%) received preoperative EDS. After controlling for patient clinical and demographic characteristics, CTS-6 scores were not associated with receiving any preoperative EDS (lower probability of CTS: odds ratio [OR], 0.94; 95% confidence interval [95% CI], 0.59–1.51), preconsultation EDS (low probability of CTS: OR, 1.00; 95% CI, 0.73–1.38), or postconsultation EDS (low probability of CTS, OR, 1.10; 95% CI, 0.77–1.60). For use of any EDS, 9.3% of the variation in testing was explained at the practice level and 31.1% of the variation in testing was explained at the surgeon level. Conclusions Variation in EDS use is explained primarily at the practice and surgeon levels and is not related to patient clinical criteria. We recommend that providers and practices assess their use of preoperative EDS and limit its use to patients with an unclear clinical CTS diagnosis, as stated in current clinical practice guidelines. Likewise, providers should be encouraged to use the CTS-6 before prescribing EDS. Clinical relevance Limiting the use of EDS to patients with an unclear clinical diagnosis of CTS will reduce costs and improve patient care by eliminating the discomfort and time associated with this test.

Background Bone grafting during primary reverse shoulder arthroplasty (RSA) is a technique used to restore poor glenoid bone, increase lateralization, and restore abnormal inclination or version. The purpose of this article is to analyze early outcomes of bone grafting during RSA, assessing the influence of technical and patient considerations. Methods In a 4.5-year time period, 137 RSAs with glenoid bone grafting were performed with a minimum 3 months' follow-up. The mean follow-up was 17 months (range, 3-38). The mean age was 71 years (range, 45-89), and body mass index was 28 (range, 19-44). The source of the autografts were humeral head (n = 113) and iliac crest autograft (ICBG; n = 24). The humeral components included 84 onlay and 53 inlay designs. Results Overall, there were 16 complications (12%), of which 6 were major (5%) (3 graft nonunions and 3 infections) and 10 minor (8%) (1 carpal tunnel syndrome and 9 transient axillary neuropraxias). Of the 9 axillary neuropraxias, 8 resolved by the most recent follow-up, whereas 1 patient was lost to follow-up. There were 4 reoperations (3%): 2 for glenoid baseplate loosening, 1 for severe notching associated with severe glenoid bone loss, and 1 for deep periprosthetic infection. One additional patient had a baseplate failure and is undergoing further treatment. There was no difference in the occurrence of graft nonunions, revision surgery, or glenoid component loosening when comparing type of graft or humeral component used. There was an association of revision surgery (P = .02) with ICBG and older age at the time of surgery (P = .02) and an association of transient neuroapraxia with onlay humeral components (P = .01) and workers' compensation cases (P = .04). Conclusions There is a high union rate and low complication rate after bone grafting of the glenoid performed with RSA. Transient neuropraxias are the most frequent complication, but the majority resolve within the first postoperative year. These early findings can serve as the basis for future long-term, comprehensive analysis of complications and outcomes after bone grafting during RSA.

The incidence of total shoulder arthroplasty (TSA) continues to increase. Although researchers expect preoperative depression to influence outcomes following primary hip and knee arthroplasty, there is a paucity of data on this relationship after primary TSA. The purpose of this study was to define the relationship between a preoperative diagnosis of depression and postoperative outcomes following TSA.This was a level III retrospective cohort study. We identified patients undergoing TSA between 2009 and 2017 from the Truven MarketScan database and created 2 cohorts, patients with and without depression. We included patients who were continuously enrolled in the database for 1 year preoperatively and postoperatively. We collected demographic data, complication data, and health care utilization factors and then performed statistical analysis comparing complication and health care utilization between cohorts. This analysis controlled for baseline patient demographic, comorbid, and surgical factors.We included 22,623 patients undergoing TSA in this study. Of these, 3209 (14%) had a preoperative diagnosis of depression. Multivariate analysis demonstrated that the following were more common in patients with depression: sepsis (odds ratio [OR], 2.04; 95% confidence interval [CI], 1.14-3.65; P = .022), revision within 1 year (OR, 1.92; 95% CI, 1.45-2.55; P.001), prosthetic joint infection within 1 year (OR, 1.41; 95% CI, 1.04-1.90; P = .025), return to the operating room for irrigation and débridement (OR, 2.72; 95% CI, 1.67-4.42; P.001), prosthetic complication (OR, 1.54; 95% CI, 1.26-1.88; P.001), and wound complication (OR, 1.84; 95% CI, 1.2-2.79; P = .004). Similarly, patients with depression had greater health care utilization including higher odds of non-home discharge (OR, 1.43; 95% CI, 1.3-1.57; P.001), 90-day readmission (OR, 1.55; 95% CI, 1.3-1.86; P.001), 90-day emergency department visit (OR, 1.39; 95% CI, 1.23-1.57; P.001), and extended length of stay (≥3 days; OR, 1.23; 95% CI, 1.12-1.36; P.001).Depression prior to TSA is common and is associated with increased risk of complications and increased health care utilization following TSA. Determining whether this is a modifiable risk factor requires further investigation.
