RESUMEN
PURPOSE: Wrist arthroscopy is considered the gold standard for diagnosis of intra-articular wrist conditions including triangular fibrocartilage complex (TFCC) tears; however, the ability to reliably diagnose TFCC pathology during wrist arthroscopy is unclear. The purpose of this study was to assess the reliability of the diagnosis of TFCC tears on wrist arthroscopy videos. METHODS: Five hand surgeons reviewed 43 cases on a secure web-based platform at two time points separated by 4-6 weeks. Each case included a deidentified clinical vignette and wrist radiographs with ulnar variance measurements and an arthroscopy video of ulnar wrist pathology, averaging 42 seconds. Surgeons were queried on the presence of TFCC tear and Palmer and Atzei classifications. Interobserver/intraobserver reliabilities were determined using kappa coefficients. RESULTS: The interobserver reliability regarding the presence/absence of TFCC tear was fair-good, with kappa coefficients of 0.596 in the first round of case review and 0.708 in the second round. The overall intraobserver reliability for the presence/absence of TFCC tear was also fair-good, with a kappa coefficient of 0.567. For cases with central TFCC tears, the interobserver reliability regarding the presence of TFCC tear was perfect, with a kappa coefficient of 1.0. When central tears were excluded, the kappa coefficients decreased to 0.322 and 0.368 in each round. The interobserver reliability for the Palmer and Atzei classifications was low, with kappa coefficients of 0.220 and 0.121 in the first round and 0.222 and 0.123 in the second round. CONCLUSIONS: Experienced wrist arthroscopy surgeons demonstrated fair-good interobserver reliability for the diagnosis of TFCC tear on wrist arthroscopy. However, when central TFCC tears were excluded, interobserver reliability was poor. These findings demonstrate a need for a focus on education for wrist arthroscopy anatomy. CLINICAL RELEVANCE: This investigation demonstrated poor agreement in surgeon identification and classification of TFCC tears, aside from central TFCC tears. The low reliability has a direct bearing on treatment considerations for TFCC tears.
RESUMEN
PURPOSE: Microsuture neurorrhaphy is technically challenging and has inherent drawbacks. This study evaluated the potential of a novel, sutureless nerve coaptation device to improve efficiency and precision. METHODS: Twelve surgeons participated in this study-six attending hand/microsurgeons and six trainees (orthopedic and plastic surgery residents or hand surgery fellows). Twenty-four cadaver arm specimens were used, and nerve repairs were performed at six sites in each specimen-the median and ulnar nerves in the proximal forearm, the median and ulnar nerves in the distal forearm, and the common digital nerves to the second and third web spaces. Each study participant performed nerve repairs at all six injury locations in two different cadaver arms (n = 12 total repairs for each participating surgeon). The nerve repairs were timed, tested for tensile strength, and graded for alignment and technical repair quality. RESULTS: A substantial reduction in time was required to perform repairs with the novel coaptation device (1.6 ± 0.8 minutes) compared with microsuture (7.2 ± 3.6 minutes). Device repairs were judged clinically acceptable (scoring "Excellent" or "Good" by most of the expert panel) in 97% of the repairs; the percentage of suture repairs receiving Excellent/Good scores by most of the expert panel was 69.4% for attending surgeons and 36.1% for trainees. The device repairs exhibited a higher average peak tensile force (7.0 ± 3.6 N) compared with suture repairs (2.6 ± 1.6 N). CONCLUSIONS: Nerve repairs performed with a novel repair device were performed faster and with higher technical precision than those performed using microsutures. Device repairs had substantially greater tensile strength than microsuture repairs. CLINICAL RELEVANCE: The evaluated novel nerve repair device may improve surgical efficiency and nerve repair quality.

PURPOSE: The purpose of this study was to analyze the quality and readability of the information generated by an online artificial intelligence (AI) platform regarding 4 common hand surgeries and to compare AI-generated responses to those provided in the informational articles published by the American Society for Surgery of the Hand (ASSH) HandCare website. METHODS: An open AI model (ChatGPT) was used to answer questions commonly asked by patients on 4 common hand surgeries (carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fracture fixation). These answers were evaluated for medical accuracy, quality and readability and compared to answers derived from the ASSH HandCare materials. RESULTS: For the AI model, the Journal of the American Medical Association benchmark criteria score was 0/4, and the DISCERN score was 58 (considered good). The areas in which the AI model lost points were primarily related to the lack of attribution, reliability and currency of the source material. For AI responses, the mean Flesch Kinkaid Reading Ease score was 15, and the Flesch Kinkaid Grade Level was 34, which is considered to be college level. For comparison, ASSH HandCare materials scored 3/4 on the Journal of the American Medical Association Benchmark, 71 on DISCERN (excellent), 9 on Flesch Kinkaid Grade Level, and 60 on Flesch Kinkaid Reading Ease score (eighth/ninth grade level). CONCLUSION: An AI language model (ChatGPT) provided generally high-quality answers to frequently asked questions relating to the common hand procedures queried, but it is unclear when or where these answers came from without citations to source material. Furthermore, a high reading level was required to comprehend the information presented. The AI software repeatedly referenced the need to discuss these questions with a surgeon, the importance of shared decision-making and individualized care, and compliance with surgeon treatment recommendations. CLINICAL RELEVANCE: As novel AI applications become increasingly mainstream, hand surgeons must understand the limitations and ramifications these technologies have for patient care.

PURPOSE: The purpose of this study was to compare the rates of wound complications and heterotopic ossification (HO) between patients who underwent acute total elbow arthroplasty (TEA) and those who underwent delayed TEA performed for the treatment of distal humerus fractures. Our hypothesis was that delayed surgery will have fewer wound complications but a higher rate of HO. METHODS: We retrospectively reviewed 104 patients who had undergone TEA performed at 1 of 3 institutions following a distal humerus fracture. The acute cohort, comprising 69 patients, underwent TEA within 2 weeks; the delayed cohort, comprising 35 patients, received treatment between 2 weeks and 6 months. The rates of wound complications, HO, clinically relevant HO (requiring excision or resulting in loss of functional range of motion), and reoperation were recorded. These patients were followed up for an average of 52 (interquartile range, 18.5-117) weeks. RESULTS: Wound complications occurred in 10 patients (14.5%) in the early group and 7 (20.0%) in the delayed group. The overall rate of HO was 56.7% (59 patients). The rate of clinically relevant HO was 26.0% (27 patients), which was similar between the groups. Reoperation occurred in 20 patients (19.2%), which was similar between the groups. In the early group, 3 reoperations were performed for wound complications and 4 for HO. No patients required reoperation for these indications in the delayed group. The mean flexion-extension and supination-pronation arcs were 20°-130° and 80°-80°, respectively, which were similar between the groups. Rheumatoid arthritis and younger age were associated with increased odds of wound complications and reoperation. CONCLUSIONS: The rates of reoperation, wound complications, and HO were overall higher than those previously reported; however, the study was underpowered to determine a difference between early and delayed treatment. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
RESUMEN
PURPOSE: Carpal tunnel syndrome requires multiple decisions during its management, including regarding preoperative studies, surgical technique, and postoperative wound management. Whether patients have varying preferences for the degree to which they share in decisions during different phases of care has not been explored. The goal of our study was to evaluate the degree to which patients want to be involved along the care pathway in the management of carpal tunnel syndrome. METHODS: We performed a prospective, multicenter study of patients undergoing carpal tunnel surgery at 5 academic medical centers. Patients received a 27-item questionnaire to rate their preferred level of involvement for decisions made during 3 phases of care for carpal tunnel surgery: preoperative, intraoperative, and postoperative. Preferences for participation were quantified using the Control Preferences Scale. These questions were scored on a scale of 0 to 4, with patient-only decisions scoring 0, semiactive decisions scoring 1, equally collaborative decisions scoring 2, semipassive decisions scoring 3, and physician-only decisions scoring 4. Descriptive statistics were calculated. RESULTS: Seventy-one patients completed the survey between November 2018 and April 2019. Overall, patients preferred semipassive decisions in all phases of care (median score, 3). Patients preferred equally collaborative decisions for preoperative decisions (median score, 2). Patients preferred a semipassive decision-making role for intraoperative and postoperative decisions (median score, 3), suggesting these did not need to be equally shared. CONCLUSIONS: Patients with carpal tunnel syndrome prefer varying degrees of involvement in the decision-making process of their care and prefer a semipassive role in intraoperative and postoperative decisions. CLINICAL RELEVANCE: Strategies to engage patients to varying degrees for all decisions during the management of carpal tunnel syndrome, such as decision aids for preoperative surgical decisions and educational handouts for intraoperative decisions, may facilitate aligning decisions with patient preferences for shared decision-making.

PURPOSE: As the burden of surgical care and the associated outreach trips to low- and middle-income countries increases, it is important to collect postoperative data to assess and improve the quality, safety, and efficacy of the care provided. In this pilot study, we aimed to evaluate the feasibility of short message service (SMS)-based mobile phone follow up to obtain patient-reported outcome measures after hand surgery during a surgical outreach trip to Vietnam. METHODS: Patients undergoing surgery during a week-long outreach trip to Hospital 175 in Ho Chi Minh City, Vietnam, who owned a mobile phone, were included in this study. Eight eligible patients elected to participate and were sent an SMS-based, Health Insurance Portability and Accountability Act-compliant text message with a link to a contextualized shortened Disabilities of the Arm, Shoulder and Hand questionnaire at 1 day, 1 week, 2 weeks, 4 weeks, and 12 weeks after the surgery. The patient characteristics and instrument completion rates were reported. RESULTS: The 8 patients had a mean age of 45.4 years and lived at a mean distance of 72.7 km from the hospital. Seven (87.5%), 7 (87.5%), 8 (100%), 6 (75%), and 8 (100%) patients completed the follow-up questionnaires at 1 day, 1 week, 2 weeks, 4 weeks, and 12 weeks after the surgery, respectively. CONCLUSIONS: This pilot study demonstrates that the collection of patient-reported outcome measures after hand surgery outreach trips to low- and middle-income countries via SMS-based messaging is feasible for up to 12 weeks after the surgery. CLINICAL RELEVANCE: Short message service-based messaging can be used to obtain postoperative outcome measures for up to 12 weeks after surgical outreach trips to low- and middle-income countries. This technology can be scaled and contextualized based on location to ensure that patient care during outreach trips is safe and effective.

Isolated dislocation of the scaphoid is a rare injury with only a few case reports in the literature. We report on 2 complex scaphoid dislocations demonstrating concomitant axial instability with disruption of the capitohamate articulation as well as the long-ring metacarpal relationship. Both of these patients underwent reduction and fixation using a wrist spanning plate, which was removed approximately 2 months after injury. Follow-up of these patients demonstrated maintenance of reduction, axial stability, and return of painless range of motion.

BACKGROUND: Both platelet-rich plasma (PRP) and corticosteroid injections may be used to treat lateral epicondylitis. We evaluated the cost-effectiveness of PRP injections vs. corticosteroid injections for the treatment of recalcitrant lateral epicondylitis. METHODS: Markov modeling was used to analyze the base-case 45-year-old patient with recalcitrant lateral epicondylitis, unresponsive to conservative measures, treated with a single injection of PRP or triamcinolone 40 mg/mL. Transition probabilities were derived from randomized controlled trials, quality-of-life (QOL) values from the Tufts University Cost-Effectiveness Analysis Registry reported using Disabilities of the Arm, Shoulder, and Hand (DASH) scores, and costs from institution financial records. Analyses were performed from health care and societal perspectives. Outcomes were incremental cost-effectiveness ratios (ICERs), reported as US dollars / quality-adjusted life-year (USDs/QALY) and net monetary benefit (NMB) to represent the values of an intervention in monetary terms. Willingness-to-pay thresholds were set at $50,000 and $100,000. Deterministic and probabilistic sensitivity analyses were performed over 10,000 iterations. RESULTS: Both PRP and triamcinolone 40-mg/mL injections were considered cost-effective interventions from a health care and societal perspective below the WTP threshold of $50,000. From a health care perspective, PRP injections were dominant compared with triamcinolone 40-mg/mL injections, with an ICER of -$5846.97/QALY. PRP injections provided an NMB of $217,863.98, whereas triamcinolone 40 mg/mL provided an NMB of $197,534.18. From a societal perspective, PRP injections were dominant compared to triamcinolone 40-mg/mL injections, with an ICER of -$9392.33/QALY. PRP injections provided an NMB of $214,820.16, whereas triamcinolone 40 mg/mL provided an NMB of $193,199.75. CONCLUSIONS: Both PRP and triamcinolone 40-mg/mL injections provided cost-effective treatments from health care and societal perspectives. Overall, PRP injections were the dominant treatment, with the greatest NMB for recalcitrant lateral epicondylitis over the time horizon of 5 years.

BACKGROUND: Movement toward providing value-based musculoskeletal care requires understanding the cost associated with surgical care as well as the drivers of these costs. The aim of this study was to investigate the effect of common medical comorbidities and specific total elbow arthroplasty (TEA) indications on reimbursement costs throughout the 90-day TEA episode of care. The secondary aim was to identify the drivers of these costs. METHODS: Administrative health claims for patients who underwent orthopedic intervention between 2010 and 2020 were queried using specific disease classification and procedural terminology codes from a commercially available national database of 53 million patients. Patients with commercial insurance were divided into various cohorts determined by different surgical indications and medical comorbidities. The reimbursement costs of the surgical encounter, 89-day postoperative period, and total 90-day period in each cohort were evaluated. The cost drivers for the 89-day postoperative period were also determined. Analyses were performed using descriptive statistics and the Kruskal-Wallis test for comparison. RESULTS: A total of 378 patients who underwent TEA were identified. The mean reimbursement cost of the surgical encounter ($13,393 ± $8314) did not differ significantly based on patient factors. The mean reimbursement cost of the 89-day postoperative period ($4232 ± $2343) differed significantly when stratified by surgical indication (P < .0001) or by medical comorbidity (P < .0001). The indication of rheumatoid arthritis ($4864 ± $1136) and the comorbidity of chronic kidney disease ($5873 ± $1165) had the most expensive postoperative period. In addition, the total 90-day reimbursement cost ($16,982 ± $4132) differed significantly when stratified by surgical indication (P = .00083) or by medical comorbidity (P < .0001), with the indication of acute fracture ($18,870 ± $3971) and the comorbidity of chronic pulmonary disease ($19,194 ± $3829) showing the highest total 90-day cost. Inpatient costs related to readmissions represented 38% of the total reimbursement cost. The overall readmission rate was 5.0%, and the mean readmission cost was $16,296. CONCLUSION: TEA reimbursements are significantly influenced by surgical indications and medical comorbidities during the postoperative period and the total 90-day episode of care. As the United States transitions to delivering value-based health care, the need for surgeons and policy makers to understand treatment costs associated with different patient-level factors will expand.

PURPOSE: The objective of this study is to evaluate the effect of absolute stability (AS) versus relative stability (RS) performed through a minimally invasive plate osteosynthesis (MIPO) in AO/OTA 12A1 and 12A2 fractures on healing and the time to radiographic union. METHODS: This was a retrospective cohort study of all patients treated with plate fixation for AO/OTA type 12A1-A2 fractures at a single institution. Patients were grouped according to the type of stability used in their surgery. Time until radiographic union was estimated using the Kaplan-Meier method, which was compared by long-rank test between both types of surgical techniques. RESULTS: A total of 70 patients were included in this study with 35 patients in each group. The median follow-up was 9 (IQR 6-14) months. The median time to radiographic union was significantly lower in the AS group than in the RS group: 12 (interquartile range (IQR) 10-14) weeks versus 18 (IQR 16-19) weeks, respectively (p < 0.001). Non-union was seen in two cases (7%) in the relative stability group. Three patients in the RS group developed a post-operative radial nerve palsy. CONCLUSION: The main finding of this study is that the median time to radiographic union was significantly shorter in the patients treated with AS compared to those with a RS technique. These findings support the recommendations of the AO foundation in that simple metaphyseal fractures (type A) that require surgical treatment should be treated with an AS construct. RS techniques should be reserved to multifragmentary fractures where fragment preservation of blood supply is paramount.

PURPOSE: The purpose of this study was to test the null hypothesis that there is no association between perioperative laboratory markers (serum albumin and hemoglobin A1c [HbA1c]) and incidence of surgical site infection (SSI) after soft tissue upper extremity surgery. METHODS: We analyzed patient-level data from a large, insurance-based database containing supplemental laboratory results. We identified patients undergoing soft tissue upper extremity surgery (defined as carpal tunnel release, trigger finger release, wrist ganglion excision, cubital tunnel release, Dupuytren partial fasciectomy, or first dorsal compartment release) with serum albumin or HbA1c measurements within 90 days of surgery. We stratified patients into cohorts based on serum albumin concentration (<3.5 g/dL) and HbA1c (≥7%) thresholds. The primary outcome was incidence of SSI within 30 days following surgery. We constructed multivariable logistic regression models to adjust for patient demographics and baseline comorbidities using the Elixhauser comorbidity index. RESULTS: Patients with hypoalbuminemia experienced an SSI incidence of 3.5% compared to 0.9% in patients with normal serum albumin. In multivariable analysis, the odds ratio of SSI with hypoalbuminemia was 3.32 (95% CI, 2.32-4.65). Patients with HbA1c ≥ 7% experienced an SSI incidence of 1.1% compared to 0.7% in patients with HbA1c < 7%. Multivariable analysis revealed odds ratios for SSI of 1.47 (95% CI, 1.02-2.11) in patients with HbA1c ≥ 7% compared to those with HbA1c < 7%. CONCLUSIONS: Hypoalbuminemia and elevated HbA1c (in patients with diabetes) are risk factors for SSI within 30 days following soft tissue upper extremity surgery. Preoperative measurement of these laboratory markers may be a useful tool for risk stratification and identification of high-risk patients for nutritional or glycemic optimization. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

PURPOSE: The purpose of this study was to evaluate a series of intra-articular distal radius fractures (DRFs) to determine whether patients without radiographic evidence of scapholunate (SL) ligament injury have a difference in outcomes in comparison with patients with radiographic evidence of SL ligament injury and no ligament repair or reconstruction. Our hypothesis is that there are no significant differences in outcomes between patients after treatment of their intra-articular DRF. METHODS: A retrospective analysis of patients from a single institution who sustained an intra-articular DRF from January 2006 through January 2019 with minimum 12-month (n = 192) and 24-month (n = 100) follow-up was performed. Patient demographic, clinical, and outcome variables were compared between SL angles less than 70° (cohort 1) and SL angles 70° or greater (cohort 2). Radiographic parameters were measured and recorded at 3 time points: baseline in the contralateral wrist, following closed reduction but prior to surgical intervention, and at final follow-up. Outcomes collected included Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), Modified Global Assessment of Function (mGAF), and a visual analog scale (VAS) for pain. RESULTS: One hundred ninety-two patients were included. Of these 192 patients, cohort 1 (n = 110) was observed to have median (range) SL angles of 58° (42°-68°) and cohort 2 (n = 82) median (range) SL angles of 74.5° (70°-87°) after closed reduction. Cohort 2 had statistically significant increases in median SL angles from closed reduction to final follow-up (74.5° [range, 70°-87°) to 78.5° (range, 71°-107°). There were no statistically significant differences in QuickDASH disability scores, mGAF scores, and VAS pain scores between the cohorts at initial and final follow-ups. CONCLUSIONS: Patient-reported outcomes at 12 and 24 months do not differ between patients without radiographically apparent SL ligament injury (SL angles < 70°) and patients with radiographically apparent SL ligament injury(SL angles ≥ 70°) who do not undergo ligament repair or reconstruction following treatment of their intra-articular DRF. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: Attending surgeons must participate in critical and key portions of procedures and otherwise be immediately available. However, surgeon-defined standards of the critical and key portions of surgery have been questioned, potentially affecting trainee graduated responsibility. This study compares the opinions of surgeons and the general public regarding what constitutes the critical portions of carpal tunnel release (CTR). METHODS: A survey was devised inquiring about the appropriateness of surgical trainee execution of each step of CTR. Surgeons who perform CTR were queried (n = 112) and 32 (29%) responded. The survey was modified to compare responses from a sample of 184 nonmedical respondents (NMRs). The NMRs were excluded if they indicated having a career in health care. RESULTS: Of the surgeon respondents, 94% (n = 30) had completed hand fellowship training, 53% (n = 17) declared themselves academic or affiliated with academia, and 53% (n = 17) utilized concurrent operating rooms. The NMR average age was 35.3 ± 10.3 years, 40% were female (n = 73), and they represented various regions of the United States including an assortment of socioeconomic and ethnic groups. Surgeons demonstrated significantly more hesitation with trainees performing surgical steps. Academic surgeons were significantly more comfortable having trainees performing surgical steps than nonacademic surgeons. Critical portions of CTR as agreed upon by surgeons and NMRs included incision, dissection, transverse carpal ligament division, and inspection of the median nerve for injury/complete release. CONCLUSIONS: Surgeons are significantly less comfortable with trainee performance of CTR steps than the general public. Surgeons who regularly work with trainees are more accepting of trainee involvement than those who do not. CLINICAL RELEVANCE: Understanding the opinions of surgeons as well as NMRs with respect to surgical trainee participation in the operating room is important to optimize the informed consent process as well as influence hospital policies that affect graduated surgical trainee autonomy.

BACKGROUND: Total elbow arthroplasty (TEA) has a higher rate of revision and complications than other total joint arthroplasties. Salvage options for failed TEAs are limited, especially when patients have poor ulna bone stock. The purpose of this study is to describe a surgical technique and report outcomes of patients who underwent revision TEA with implantation of the ulnar component into the radius to address ulna bony defects. METHODS: A retrospective review of 5 patients at a single institution from 2014 to 2019 in which the ulnar component was implanted into the radius to address large bony defects in the setting of revision TEA was performed. RESULTS: At follow-up of 2.1 ± 1.9 years, patients experienced an increase in total arc of motion from 86 ± 17° to 112 ± 8°, with infection eradication and no instances of distal component loosening. CONCLUSION: This salvage technique was effective at providing a stable elbow in patients with large ulna bony defects as a result of prosthetic joint infection or periprosthetic fracture.

BACKGROUND: Relative value units (RVUs) are an essential component of reimbursement calculations from the Centers for Medicare & Medicaid Services. RVUs are calculated based on physician work, practice expense, and professional liability insurance. Procedures that are more complex, such as revision arthroplasty, require greater levels of physician work and should therefore be assigned a greater RVU. The purpose of this study is to compare RVUs assigned for primary and revision total elbow arthroplasty (TEA). METHODS: The National Surgical Quality Improvement Program database was used to collect all primary and revision total elbow arthroplasties performed between January 2015 and December 2017. Variables collected included age at time of surgery, RVUs assigned for the procedure, and operative time. RESULTS: A total of 359 cases (282 primary TEA, 77 revision TEA) were included in this study. Mean RVUs for primary TEA was 21.4 (2.0 standard deviation [SD]) vs. 24.4 (1.7 SD) for revision arthroplasty (P < .001). Mean operative time for primary TEA was 137.9 minutes (24.4 SD) vs. 185.5 minutes (99.7 SD) for revision TEA (P < .001). The RVU per minute for primary TEA was 0.16 and revision TEA was 0.13 (P < .001). This amounts to a yearly reimbursement difference of $71,024 in favor of primary TEA over revision TEA. CONCLUSION: The current reimbursement model does not adequately account for increased operative time, technical demand, and pre- and postoperative care associated with revision elbow arthroplasty compared with primary TEA. This leads to a financial advantage on performing primary TEA.

INTRODUCTION: Heterotopic ossification (HO) is a well-known sequela after an elbow injury and is widely studied given the associated morbidity. The anatomic location of HO development for specific elbow injuries has not been reported. The purpose of this study was to describe the precise, anatomic location of HO development after different peri-articular elbow injuries. METHODS: A retrospective chart review was performed for patients with peri-articular elbow fracture and/or dislocation who underwent an elbow contracture release. The injuries were grouped into coronal shear distal humerus/AO 13.B3 (CSDH), distal humerus/AO 13.A, 13.B1, B2 or 13.C (DH), olecranon/AO 21.B1 (OL), radial head/AO 21.B2 (RH), extra-articular proximal radius and ulna/AO 21.A (EAPRU) fractures and elbow dislocations (DL). The HO location was determined by reviewing elbow radiographs and CT scans and were classified as anterior capsule, medial or lateral collateral ligaments, and posterior capsule/triceps insertion. RESULTS: The study consisted of 49 patients, such as 6 CSDH, 13 DH, 6 OL, 21 RH, 4 EAPRU fractures and 20 elbow DL. All CSDH and RH fractures and 19/20 elbow DL developed HO in the collateral ligaments, while 12/13 DH fractures developed an anterior capsule HO. All 6 OL fractures developed HO posteriorly, and 3/4 EAPRU fractures developed a proximal radioulnar synostosis. CONCLUSIONS: Our findings suggest that the location of HO development is specific to the injury type and is influenced by the soft tissues involved. This is consistent with the understanding that HO is the abnormal ossification of normal structures.

Hand transplantation is the most common application of vascularized composite allotransplantation (VCA). Since July 3, 2014, VCAs were added to the definition of organs covered by federal regulation (the Organ Procurement and Transplantation Network (OPTN) Final Rule) and legislation (the National Organ Transplant Act). As such, VCA is subject to requirements including data submission. We performed an analysis of recipients reported to the OPTN to have received hand transplantation between 1999 and 2018. Forty-three patients were identified as having been listed for upper extremity transplantation in the United States. Of these, 22 received transplantation prior to July 3, 2014 and 10 from then to December 31, 2018. Of patients transplanted after 2014, posttransplant functional scores included a decrease in Disabilities of the Arm, Shoulder and Hand questionnaire in 3 of 10 patients, Carroll test scores ranging from 9 to 60 of 99, and monofilament testing with protective sensation achieved in 4 of 6 patients. Complications included rejection in nine recipients with Banff scores from II-IV. One patient experienced graft failure 5 days after transplantation. Of the remaining patients, two were reported as receiving monotherapy and seven receiving dual or triple immunosuppression therapy. The inclusion of VCA in the OPTN Final Rule standardized parameters for safe implementation and data collection.

Adult forearm nonunion should be investigated prior to developing a treatment strategy: "Why did the fracture not heal?" Optimizing the patient's biology and the stability at the nonunion site are critical for a successful outcome. This review concisely discusses the initial work-up, including history, physical examination, imaging, and laboratory testing, as well as available surgical techniques-irrigation and debridement with deep cultures, revision open reduction internal fixation with or without biological adjuvant therapies, cancellous autograft, tricortical iliac crest, reamer/irrigator/aspirator, allograft, vascularized free-fibula and induced-membrane technique.

PURPOSE: To evaluate outcomes of intra-articular distal radius fractures with displaced dorsal lunate facet fragments treated with a combination of volar plating and the use of a dorsal screw that integrates into the plate. METHODS: We reviewed a retrospective cohort of 22 patients who underwent open reduction and internal fixation of an intra-articular distal radius fracture with a volar plate in conjunction with the Frag-Loc Compression screw. Patient charts and radiographs were reviewed for clinical and radiographic outcomes. RESULTS: A total of 12 patients with a minimum 6-month follow-up who met all eligibility criteria were included in this study. There were 8 women and 4 men. The mean age was 55.2 years. Mean follow-up was 11.5 months (range, 6-21 months). The most common mechanism of injury was a fall from standing (75.0%). At final follow-up, all patients were able to return to their previous level of function. Bony union was achieved in all patients at the time of final follow-up. Average radiographic parameters at final follow-up were radial inclination 24.2° ± 5.3°, volar tilt 1.3° ± 5.2°, and ulnar variance 0.9 ± 1.7 mm. During the follow-up period, transient median nerve paresthesias were observed in 4 patients, with spontaneous resolution in 3 of 4 patients. Loss of articular reduction was not observed in any case. CONCLUSIONS: This study demonstrates satisfactory clinical and radiographic results and minimal complications with utilization of a new fixation device for distal radius fractures with displaced dorsal lunate facet fragments. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: The purpose of this study was to investigate changes in length of the volar and dorsal radioulnar ligaments (VRULs and DRULs), and the distal radioulnar joint (DRUJ) space during unweighted and weighted rotation of the wrist using magnetic resonance imaging and biplanar fluoroscopy. METHODS: Fourteen wrists in 7 normal adult volunteers were imaged to define the 3-dimensional geometry of the DRUJ and the insertion sites of the superficial and deep bundles of the VRULs and DRULs. Subjects were imaged at 10 positions of forearm rotation ranging from full pronation to full supination, with or without a 5-pound weight. Lengths of the superficial and deep VRUL and DRUL bundles and DRUJ space were measured (in millimeters) at each position to evaluate ligament function and DRUJ stability. RESULTS: In the unweighted and weighted trials, maximal elongation of both deep and superficial VRUL bundles occurred in supination and maximal lengths of the deep and superficial DRUL bundles occurred in pronation. Maximum DRUJ space occurred during pronation and a minimum occurred in 30° of supination. In weighted trials, there was a significant increase in deep and superficial VRUL bundle length at positions between 30° of pronation and 30° of supination; however, there was no effect of weight on DRULs length. In weighted trials, there was a significant increase in DRUJ space at positions between full pronation and 15° of supination. CONCLUSIONS: This study demonstrates elongation of the VRULs in supination and the DRULs in pronation. There was no evidence of reciprocal loading of superficial/deep ligament bundles on either the dorsal or the volar aspects of the DRUJ. The effect of loading the wrist during rotation was apparent primarily in the VRULs, but not the DRULs. The DRUJ space was lowest at approximately 30° of supination. CLINICAL RELEVANCE: These results add information to the literature regarding the complicated biomechanics of the triangular fibrocartilage complex and DRUJ. Future work should evaluate changes in biomechanics caused by triangular fibrocartilage complex tears to determine how tear severity and location relate to clinical symptoms.
