Abstract
PURPOSE Traction tenolysis is an alternative, less invasive way of performing flexor tendon tenolysis by winding affected tendons around a surgical instrument. This study assessed outcomes and complications in a cohort of patients who underwent traction tenolysis to determine its effectiveness. METHODS We retrospectively reviewed 97 patients who underwent traction tenolysis performed by 4 fellowship-trained hand surgeons from 2010 to 2019. We collected data on preoperative and postoperative ranges of motion, the number and type of prior ipsilateral hand surgeries, and the duration of therapy and follow-up. Cases of traditional open tenosynovectomy tenolysis were excluded. RESULTS Approximately two-thirds of the patients achieved more than 75% of the normal total active motion, and 80% achieved at least 50% of the normal total active motion. The mean total active flexion increased significantly by 42° and passive flexion by 25°. The differences in active and passive flexion significantly decreased from 28° before the surgery to 9° after the surgery. The active and passive flexion of the distal interphalangeal and proximal interphalangeal joints improved similarly, at approximately 20° and 10°, respectively. The average duration of follow-up was 11 ± 8 weeks. The complication rate was 5%: 1 case of intraoperative flexor digitorum superficialis tendon rupture, 1 case of postoperative infection, and 3 reoperations because of failure to progress. CONCLUSIONS Traction tenolysis is an alternative to traditional open tenolysis surgery in selected patients. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Purpose There is a paucity of data regarding recommendations on when to correct for distal radius malunions and if the initial severity of the radiographic outcomes is correlated with the ability to correct to baseline. We evaluated the effects of distal radius corrective osteotomy on preoperative carpal joint malalignment resulting from distal radius malunions, correlated injury severity and osteotomy timing to radiographic outcomes, and developed a straightforward classification system for predicting radiocarpal and midcarpal maladaptive patterns. Methods A retrospective review included 26 patients (27 wrists) who reported initial closed treatment for a distal radius fracture and who subsequently underwent a corrective osteotomy for malunion. Data included patient demographics, range of motion, preoperative fracture deformity, fracture deformity correction, and preoperative and postoperative radiographic measurements of the radiocarpal and midcarpal alignment patterns. Results Of 27 dorsally angulated malunions, 16 were classified as type 1 midcarpal adaptation and 11 as type 2 radiocarpal adaptation. The midcarpal group showed significant improvements in distal radius and carpal alignment parameters after surgery, except for the ulnar variance. The radiocarpal group showed significant improvements in distal radius and carpal alignment parameters, except for the radiolunate angle, radioscaphoid angle, and capitolunate angle. The radiocarpal group exhibited an overall decrease in range of motion compared with that of the midcarpal group. Severity of the fracture and time taken from injury to corrective osteotomy correlated with the ability to correct carpal radiographic parameters in dorsally angulated malunions of the distal radius, especially beyond 40 weeks. Conclusions The severity of the initial fracture and time taken from injury to corrective osteotomy correlate with the ability to correct radiographic parameters in dorsally angulated malunions of the distal radius. Early correction of distal radius malunions is recommended, especially in radiocarpal malalignment patterns. A useful analysis for predicting midcarpal and radiocarpal adaptation patterns is the direct measurement of the distal articular surface of the radius to the lunate, termed the relative-radiolunate angle.

Abstract
A 62-year-old right-handed man presented with an intra-articular fracture of the proximal phalanx base of the right thumb after a motor vehicle accident. Computed tomography revealed severe comminution, apex volar angulation, and minimal bone stock at the proximal phalanx base. The patient consented to open reduction internal fixation with a locking plate to bridge the fracture and cancellous bone grafting of the distal radius. The hardware was removed at 8 weeks, without complications. The patient began therapy, and at 19 weeks following the surgery, the patient's thumb metacarpophalangeal joint motion was 10° to 30° and the interphalangeal motion was 30° to 50°. Radiographs showed fracture union and proper alignment, with modest shortening. The patient was satisfied with this result. Bridge plating may be an alternative to external fixation for certain thumb fractures, with the potential to maintain alignment and articular congruity while permitting earlier return to activities of daily living and avoiding the risk of pin-track infections.

Abstract
PURPOSE Four-corner fusion (4CF) is a surgical option for refractory scapholunate advanced collapse and scaphoid nonunion advanced collapse wrist arthritis. Preoperative range of motion (ROM) predicts outcomes in many orthopedic procedures. This study investigates ROM in a cohort of 4CF patients to examine the relationship between preoperative and postoperative motion and identifies different clinical patterns. METHODS We performed a retrospective review of 4CF patients. Patients with a history of inflammatory arthritis and radiographic characteristics of inflammation were excluded. Demographics, prior wrist surgery history, and ROM data were collected at preoperative and postoperative intervals after cast removal at 8 weeks, 3 months, and 8 months. Regression analysis compared the motion before and after 4CF. Subsequent cluster analysis to reduce confounding compared postoperative motion differences in the top 20% to the bottom 20% of patients by preoperative motion. RESULTS We included 148 patients; 27 had prior surgery on the ipsilateral wrist. Preoperative arc averaged 86° ± 28° (flexion 46° ± 17°, extension 40° ± 15°); 8-week arc 43° ± 19° (flexion 19° ± 12°, extension 24° ± 12°); 3-month arc 62° ± 17° (flexion 30° ± 12°, extension 32° ± 11°); and 8-month arc 74° ± 17° (flexion 36° ± 11°, extension 37° ± 12°). Preoperative and final arcs were (r = 0.39). Clustering by the preoperative arc, the top 20% (mean 124° ± 15°) achieved a mean final arc of 81° ± 16°, while the bottom 20% (mean 47° ± 16°) achieved a mean final arc of 65° ± 19°. Intercluster differences were statistically significant. The bottom 20% gained motion postoperatively. Most patients in the middle 60% did not differ significantly in postoperative motion. CONCLUSIONS Although wrist motion following 4CF correlates positively with preoperative motion, most patients do not differ significantly in postoperative motion. Patients with substantial preoperative motion deficits gain motion after 4CF. This information is important when counseling patients, determining the timing of surgical intervention, and managing expectations related to motion outcomes.

Abstract
Objective The aim of the study is to survey hand surgeons' perspectives on telemedicine during the coronavirus disease 2019 (COVID-19) pandemic and intended applications after the pandemic. Methods Online surveys were sent to 285 Canadian and American surgeons in late April and early May 2020. Results Response rate was 63% (180)-84% (152) American and 16% (28) Canadian. Forty-three percent (76) of respondents were in private practice, 36% (64) academics, 13% (24) privademics, and 6% (12) hospital employed. The most common telemedicine platform was Zoom. During the pandemic, 42% of patient visits were conducted via telemedicine; however, 37% required a subsequent in-person office visit. The most common complaint by surgeons was the inability to provide routine in-office procedures. The most beneficial feature was ease of use, and the most frustrating feature was connectivity difficulty. Time spent was similar to in-person visits, and surgeons were likely to recommend their platforms. Surgeons were neutral about using telehealth in the future and were most likely to use it for follow-up visits. New patient visits for traumatic injuries or fractures were of limited value. Canadians used telemedicine for a greater proportion than Americans (50 vs. 40%, p <0.05) and spent more time than in-person visits (7/10 vs. 5/10, p <0.05). Americans were more likely to use telemedicine for postoperative follow-up visits (6/10 vs. 4/10, p <0.05) and in mornings before clinic opens (4/10 vs. 2/10, p <0.05). Private practices were more likely to use telemedicine for future allied health provider visits than all other practice types ( p <0.05). Conclusion Telemedicine comprised nearly half of patient encounters during the COVID-19 pandemic, but limitations remain.

Abstract
BACKGROUND Tranexamic acid (TXA) has been effective in reducing perioperative blood loss in hip, knee, and shoulder arthroplasty. Our purpose was to assess the effect of TXA on perioperative blood loss for open elbow release. METHODS Consecutive open elbow releases performed between October 2016 and March 2020 were identified. Patients were included if both anterior and posterior joint releases with a single medial approach was performed. From November 2018 onward, intravenous TXA and topical TXA infused through a deep hemovac drain were administered as part of the perioperative protocol. Drain output, intraoperative blood loss, postoperative aspiration rate, and postoperative transfusion frequency were assessed. RESULTS Fifty patients (25 TXA, 25 non-TXA) were included. Drain output was significantly lower in the TXA-treated group compared to the non-treated group (121 mL vs. 221 mL; p = 0.003). There was no significant difference in intraoperative blood loss and the incidence of postoperative aspiration between groups. None of the patients received a blood transfusion or had a documented thromboembolic event. DISCUSSION The use of tranexamic acid with open elbow release surgeries resulted in decreased drain output, with no thromboembolic events. Perioperative tranexamic acid can be a safe and effective modality in reducing perioperative blood loss for open elbow release surgery.

Abstract
Background & Hypothesis Post-traumatic stiffness of the elbow may be treated surgically with open osteocapsular release. This study investigated postoperative range of motion (ROM) improvements after this procedure. We hypothesized that there would be predictable recovery patterns and significant progress up to 6 months after surgery. Methods A retrospective chart review of patients who underwent open elbow release for post-traumatic stiffness (PTS) was performed. Demographic information and surgical approach were recorded. Patients with ipsilateral primary elbow osteoarthritis were excluded. Range of motion (ROM) data were collected at preoperative, intraoperative, and postoperative intervals of 2 weeks, 6 weeks, 3 months, and 6 months. Growth mixture modeling (GMM) and latent class growth analysis (LCGA) were performed to identify motion recovery trajectory groups, and Student's t-tests were performed to compare ROM data between intervals. Results One hundred and eighty-seven patients who underwent open elbow release for PTS were included (112 with a medial approach, 50 lateral, and 25 both). The mean preoperative arc was 84° ± 31, and the arc of motion at final follow-up was 119° ± 19 (P < .05). The mean time to the final follow-up arc of motion was 16 weeks, with 56% of patients achieving their final arc by their 3-month follow-up visit. The largest improvement was seen with extension between 6 weeks and 3 months, where 26% of the extension at final follow-up was gained. Most of the recovery occurred within the first 3 months postoperatively, with small improvements thereafter. GMM and LCGA did not identify statistically significant groups for postoperative ROM progression trajectories. Arc of motion preoperatively, intraoperatively, and at 2 weeks postoperatively did not correlate with the final arc of motion. There were no demographic or historical characteristics, or thresholds of motion, which conferred a higher likelihood of achieving a better result postoperatively. Conclusions ROM recovery after surgical release for post-traumatic elbow stiffness did not depend on the preoperative, intraoperative, or 2-week postoperative arcs of motion. Most ROM recovery occurs early after surgery, and maximal arc of motion can be expected by approximately 16 weeks postoperatively. This knowledge may inform patients about their expected rehabilitation and splinting time and reduce the total costs of therapy.

Abstract
PURPOSE The purpose of this investigation was to examine the timeline of return-to-sport following distal triceps repair; evaluate the degree of participation and function upon returning to sport; and identify risk factors for failure to return to sport. METHODS Patients who underwent distal triceps repair with a minimum of 1 year of follow-up were retrospectively reviewed. Patients completed a subjective sports questionnaire and were scored on a visual analog scale for pain; the Mayo Elbow Performance Index; the Quick Disabilities of the Arm, Shoulder, and Hand; and the Single Assessment Numerical Evaluation. RESULTS Out of 113 eligible patients who had a distal triceps repair, 81 patients (71.7%) were contacted. Sixty-eight patients (84.0%) who participated in sports prior to surgery were included at 6.0 ± 4.0 years after surgery, and the average age was 46.6 ± 11.5 years. Sixty-one patients (89.7%) resumed playing at least 1 sport by 5.9 ± 4.4 months following distal triceps repair. However, 18 patients (29.5%) returned to a lower level of activity intensity. The average postoperative Quick Disabilities of the Arm, Shoulder, and Hand; Mayo Elbow Performance; visual analog scale for pain; and Single Assessment Numerical Evaluation scores were 8.2 ± 14.0, 89.5 ± 13.4, 2.0 ± 1.7, and 82.2 ± 24.3, respectively. No patients underwent revision surgery at the time of final follow-up. CONCLUSIONS Distal triceps repair enables 89.7% of patients to return to sport by 5.9 ± 4.4 months following surgery. However, 29.5% of patients were unable to return to their preinjury level of activity. It is imperative that patients are appropriately educated to manage postoperative expectations regarding sport participation following distal triceps repair.

Abstract
Purpose The Evidence-Based Practice Committee of the American Society for Surgery of the Hand (ASSH) set out to assess the membership’s practice patterns (PPs) and knowledge of evidence-based principles for Dupuytren disease (DD). Methods A 21-item multiple-choice survey was distributed to all ASSH members via email in June 2020. Questions were divided into 2 types: evidence-based practice (EBP) and PPs. The survey addressed the following subtopics: nonsurgical, percutaneous, and open surgical management of DD. Results The response rate was 18% (n = 419). Of 13 EBP questions, 5 were answered with the preferred response by >75% of surgeons. The remaining 8 EBP questions had greater frequencies of less preferred responses, which concerned the current evidence for percutaneous management, as well as nonsurgical and postoperative management of DD. Of the PP questions, there were differences in opinion on how to manage a painful nodule, the percutaneous technique (eg, collagenase injection vs percutaneous needle aponeurotomy), and the choice of surgical incision for open fasciectomy (eg, Bruner incision with Z-plasties, partial closure with an open transverse palmar component, or longitudinal incision with Z-plasties). Conclusions Hand surgeons continue to be well informed about current evidence-based practices for treating DD and can improve their knowledge by familiarizing themselves with current data on percutaneous and nonsurgical methods. There exist differences in PPs for DD in the ASSH membership, specifically with less invasive management; and knowledge of peer practices can help navigate differences, critically interpret the evidence, and optimize patient care.

Abstract
BACKGROUND Patients received care over telemedicine during the COVID-19 pandemic, and their perspective is useful for hand surgeons. METHODS Online surveys were sent October-November 2020 to 497 patients who received telemedicine care. Questions were free-response and multi-item Likert scales asking about telehealth in general, limitations, benefits, comparisons to in-person visits, and opinions on future use. RESULTS The response rate was 26% (n = 130). Prior to the pandemic, 55% had not used telemedicine for hand surgery consultation. Patients liked their telemedicine visit and felt their provider spent enough time with them (means = 9/10). In all, 48% would have preferred in-person visits despite the pandemic, and 69% would prefer in-person visits once the pandemic concludes. While 43% had no concerns with telemedicine, 36% had difficulties explaining their symptoms. Telemedicine was easy to access and navigate (M = 9/10). However, 23% saw telemedicine of limited value due to the need for an in-person visit soon afterward. Of these patients, 46% needed an in-person visit due to inadequate physical examination. Factors that make telemedicine more favorable to patients included convenience, lack of travel, scheduling ease, and time saved. Factors making telemedicine less favorable included need for in-person examination or procedure, pain assessment, and poor connectivity. There was no specific appointment time the cohort preferred. Patient recommendations to improve telemedicine included decreasing wait times and showing patient queue, wait time, or physician status online. CONCLUSIONS Telemedicine was strongly liked by patients during the COVID-19 pandemic. However, nearly 70% of patients still preferred in-person visits for the future.

Abstract
Background Historically, treatment of partial articular radial head fractures has hinged on radiographic assessment and application of the Mason classification. The inter- and intra-rater reliability of radiographic assessment and classification of radial head fractures may be lower than previously reported. We hypothesized that radiographic assessment leads to an underestimation of the number of fragments, percentage of articular surface involved, and displacement in millimeters. Methods We performed a retrospective review of all Mason II radial head fractures treated at our institution. Four independent observers performed radiographic assessment of the cohort. An independent observer performed these measurements on high-resolution computed tomography (CT) imaging, the reference standard. Radiographic assessments were then correlated with the CT findings using Pearson's correlation coefficient and Kappa statistic, where indicated. Results Fifty-nine Mason II radial head fractures were reviewed. These results were not impressive, with all comparisons showing a Kappa statistic less than 0.5 (ie, weak agreement). Intra-rater reliability was similar: displacement (measured by Pearson's correlation coefficient) was 0.58, percent articular involvement was 0.74, and the number of fragments (measured by the Kappa statistic) was 0.28. Fracture displacement was generally underestimated on radiographic measurements when compared to CT scan. Nearly half (45%) of all cases demonstrated inaccurate fragment number assessment when compared to the reference standard. Conclusion Radiographs show poor inter- and intra-observer reliability for determining radial head fracture morphology. Assessment of the number of fragments was particularly inaccurate. High-resolution CT should be considered for patients with Mason II radial head fractures, especially in cases of poorly visualized fracture characteristics or borderline amounts of displacement, in an effort to appropriately indicate patients for the variety of treatment options available today.

Abstract
PURPOSE The purpose of this study was to evaluate the rate and duration of return to work in patients undergoing distal triceps repair (DTR). METHODS Consecutive patients undergoing DTR from 2009 to 2017 at our institution were retrospectively reviewed at a minimum of 1 year postoperatively. Patients completed a standardized and validated work questionnaire; a visual analog scale for pain; the Mayo Elbow Performance Score; the short version of the Disabilities of the Arm, Shoulder and Hand questionnaire; and a satisfaction survey. RESULTS Of 113 eligible patients who underwent DTR, 81 (71.7%) were contacted. Of these patients, 74 (91.4%) were employed within 3 years prior to surgery (mean age, 46.0 ± 10.7 years; mean follow-up, 5.9 ± 3.9 years). Sixty-nine patients (93.2%) returned to work by 2.2 ± 3.2 months postoperatively. Sixty-six patients (89.2%) were able to return to the same level of occupational intensity. Patients who held sedentary-, light-, medium-, and high-intensity occupations were able to return to work at a rate of 100.0%, 100.0%, 80.0%, and 76.9%, respectively, by 0.3 ± 0.5 months, 1.8 ± 1.5 months, 2.5 ± 3.6 months, and 4.8 ± 3.9 months, respectively, postoperatively. Of the workers' compensation patients, 15 (75%) returned to work by 6.5 ± 4.3 months postoperatively, whereas 100% of non-workers' compensation patients returned to work by 1.1 ± 1.6 months (P < .001). Seventy-one patients (95.9%) were at least somewhat satisfied, with 50 patients (67.6%) reporting excellent satisfaction. Seventy-two patients (97.3%) would undergo the operation again if presented the opportunity. A single patient (1.4%) required revision DTR. CONCLUSIONS Approximately 93% of patients who underwent DTR returned to work by 2.2 ± 3.2 months postoperatively. Patients with higher-intensity occupations had an equivalent rate of return to work but took longer to return to their preoperative level of occupational intensity. Information regarding return to work is imperative in preoperative patient consultation to manage expectations.

Abstract
Background: Yoga is a popular activity involving extreme wrist positioning and extension loading. Our purpose was to quantify the prevalence of preoperative yoga participation and characterize subsequent ability to return to yoga in patients undergoing volar locked plating of distal radius fractures. Methods: We retrospectively reviewed all cases of distal radius open reduction internal fixation between August 2015 and March 2017. Patients were included if they were treated with volar locked plating and if they participated in yoga on a regular basis preoperatively. Patients were contacted at a minimum of 1 year postoperatively and surveyed about yoga participation. Results: A total of 149 patients who underwent distal radius volar plating were surveyed. Thirty-one patients (32 procedures, 20.8% of surveyed patients) participated in yoga on a regular basis preoperatively. Overall, 90.3% returned to yoga in some capacity. Mean times to return to yoga in any capacity, with weight-bearing, and in a "steady state" were 5.7, 7.4, and 10.0 months, respectively. Of patients who resumed yoga, 65.5% returned to the same or better level of yoga. Satisfaction with participation in yoga was 8.9 (out of 10). Conclusions: We found a relatively high yoga participation rate in patients undergoing distal radius fracture fixation, suggesting the need to be able to effectively counsel these patients. Our results demonstrate a high rate of return to yoga, although approximately one-third of patients experienced a decreased level of participation. Surgeons can use this information to set appropriate expectations.

Abstract
Periprosthetic joint infection (PJI) is a potentially devastating complication after total elbow arthroplasty (TEA) that can lead to significant morbidity for the patient as well as increased health care-related costs. Despite the potential morbidity associated with TEA PJI, evidence is limited regarding an optimal treatment algorithm. Initial management typically consists of either irrigation and debridement or 2-stage revision. A stable implant, a functioning triceps, and an intact soft tissue envelope are necessary to perform irrigation and debridement. Irrigation and debridement is associated with a relatively high risk of infection recurrence especially in chronic infections. Two-stage revision offers a lower recurrence risk, although there is a 25% chance of not completing the second stage. Resection arthroplasty, arthrodesis, and amputation are salvage options, whereas medical treatment, in the form of antibiotics alone, is reserved for poor surgical candidates. Further multicenter prospective study and retrospective review of registry data focusing on different treatment algorithms, prevention strategies, and functional outcomes would be helpful to elucidate the ideal management of elbow PJI.

Abstract
BACKGROUND Distal biceps reconstruction for chronic rupture often requires a graft to recover length and allow for distal tendon reattachment to bone. Our purpose was to assess peak strength and endurance recovery following biceps reconstruction with tendon grafts. HYPOTHESIS We hypothesized that allograft reconstruction would result in decreased flexion and supination peak strength and endurance. METHODS Consecutive distal biceps reconstructions with allograft, performed for chronic ruptures between January 2008 and March 2018 at a single institution, were reviewed. Isokinetic dynamometry for peak strength and endurance testing was performed on the operative and contralateral arms in flexion and supination. Functional outcomes and overall satisfaction with the operation were determined. RESULTS Eleven patients were available for a complete evaluation, including dynamometry, at a mean of 46 months postoperatively. Reconstructions demonstrated a nonsignificant trend toward decreased peak flexion strength (P = .06), and significantly decreased peak supination strength (P = .01) compared with the unaffected arm. There were no differences in flexion and supination endurance between the affected and unaffected arms. Using standardized outcome scales, patients reported excellent function. CONCLUSION Chronic biceps ruptures undergoing reconstruction are highly functional and patients are satisfied. Somewhat surprisingly, supination and flexion endurance were equal to the contralateral, uninvolved arm. However, this procedure does not restore peak supination strength.

Abstract
Background: En bloc resection of the distal radius is a common treatment for advanced and recurrent giant cell tumors and less commonly for sarcoma. Various reconstructive options exist, including ulnar transposition, osteoarticular autograft and allograft, and allograft arthrodesis. We present a technique of reconstruction using a distal radius bulk allograft with a step-cut to allow for precise restoration of proper length and to promote bony union. Methods: Preoperative templating is performed with affected and contralateral radiographs to assess the size of the expected bony defect, location of the step-cut, and the optimal size of the distal radius allograft required. A standard dorsal approach to the distal radius is utilized, and the tumor is resected. A proximal row carpectomy is performed, and the plate/allograft construct is applied to the remaining host bone. Iliac crest bone graft is harvested and introduced at the graft-bone interface and radiocarpal arthrodesis sites. Results: We have previously reported outstanding union rates with the step-cut technique compared with a standard transverse cut. Conclusions: The technique described provides reproducible union and stabilization of the wrist and forearm with adequate function following en bloc resection of the distal radius for tumor.

Abstract
Background Open injuries communicating with the wrist joint are essential to detect to facilitate timely, appropriate treatment. While the saline load test to detect traumatic arthrotomy has been well studied in the knee and ankle, it has not been studied in the wrist, and therefore the appropriate volume of saline infusion to detect traumatic arthrotomy is not known. Purpose The purpose of this study was to utilize wrist arthroscopy to determine the saline infusion volume necessary to achieve 99% sensitivity in detecting traumatic arthrotomy. Methods Twenty consecutive patients undergoing elective wrist arthroscopy were prospectively enrolled. A 5-mm arthrotomy was established between the third and fourth dorsal extensor compartments. An 18-gauge needle was inserted into the 6R portal on the radial side of the extensor carpi ulnaris. Sterile normal saline was injected into the wrist joint through the needle at a rate of 0.1 mL per second until extravasation from the 3-4 portal was visualized. Saline volumes required for extravasation were analyzed. Results The mean saline volume required for extravasation was 0.8 mL. The volume of saline needed to achieve sensitivities of 50, 90, 95, and 99% were 0.4, 2.2, 2.3, and 2.5 mL respectively. Conclusions The saline infusion volume required to detect a dorsal radiocarpal arthrotomy with 99% sensitivity was 2.5 mL. We recommend using at least 2.5 mL when performing the saline load test to rule out a potential arthrotomy to the wrist in the traumatic setting. Level of Evidence: This is a Level II, diagnostic study.

Abstract
Background Few large-scale series have described functional outcomes after distal triceps tendon repair. Predictors for operative success and a comparative analysis of surgical techniques are limited in the reported literature. Purpose To evaluate short-term to midterm functional outcomes after distal triceps tendon repair in a broad patient population and to comparatively evaluate patient-reported outcomes in patients with and without pre-existing olecranon enthesopathy while also assessing for modifiable risk factors associated with adverse patient outcomes and/or revision surgery. Study Design Case series; Level of evidence, 4. Methods This study was a retrospective analysis of 69 consecutive patients who underwent surgical repair of distal triceps tendon injuries at a single institution. Demographic information, time from injury to surgery, mechanism of injury, extent of the tear, pre-existing enthesopathy, perioperative complications, and validated patient-reported outcome scores were included in the analysis. Patients with a minimum of 1-year follow-up were included. Results The most common mechanisms of injury were direct elbow trauma (44.9%), extension/lifting exercises (20.3%), overuse (17.4%), and hyperflexion or hyperextension (17.4%). Eighteen patients were identified with pre-existing symptomatic enthesopathy, and 51 tears were caused by an acute injury. A total of 36 complete and 33 partial tendon tears were identified. Bone tunnels were most commonly used (n = 30; 43.5%), while direct sutures (n = 23; 33.3%) and suture anchors (n = 13; 18.8%) were also used. Perioperative complications occurred in 21.7% of patients, but no patients experienced a rerupture at the time of final follow-up. No statistically significant relationship was found between patient age (P = .750), degree of the tear (P = .613), or surgical technique employed (P = .608) and the presence of perioperative complications. Conclusion Despite the heightened risk of perioperative complications after primary repair of distal triceps tendon injuries, the current series found favorable functional outcomes and no cases of reruptures at short-term to midterm follow-up. Furthermore, age, surgical technique, extent of the tear, and mechanism of injury were not associated with adverse patient outcomes in this investigation. Pre-existing triceps enthesopathy was shown to be associated with increased complication rates.

Abstract
BACKGROUND The Internet is a widely used resource by patients however, objective data on details such as frequency of usage and specific sites visited is lacking. We surveyed patients from hand surgery practices to describe patient preferences and utilization patterns for online resources. METHODS From October 2015 to June 2016, we enrolled patients presenting to 4 orthopedic hand surgeons at 2 academic institutions. Patients completed a survey, with questions related to their preference for learning about their diagnosis and Internet utilization both before and after the visit. RESULTS A total of 226 patients were enrolled in the study. Forty-five percent of the patients had done online research prior to the office visit, and 81% preferred to learn about their diagnosis through verbal communication, as opposed to only 8% who listed Web site information. Fifty percent indicated that there was a greater than 50% chance or they would definitely seek additional information on the Internet after the office visit. When asked to choose from a list of Web sites to visit, the most popular Web site was WebMD. Specialty society Web sites (American Society for Surgery of the Hand and American Academy of Orthopaedic Surgeons) were less popular. CONCLUSIONS This survey-based study found that a majority of patients utilize the Internet both before and after the office visit; however, they often utilize unregulated sites for information. This information can help physicians guide patients to high-quality Web sites for information on their clinical diagnosis and treatment.

Abstract
BACKGROUND Physician extenders, such as physician assistants (PAs) and nurse practitioners (NPs), have been incorporated into health systems in response to the rising demand for care. There is a paucity of literature regarding patient perspectives toward physician extenders in hand surgery. METHODS We anonymously surveyed 939 consecutive new patients before their clinic visit. Our questionnaire assessed patient perspectives toward physician extenders, including optimal scope of practice, the effect of the extender when choosing a hand surgeon, and pay equity for the same clinical services. RESULTS Of 939 patients, 784 (84%) responded: 54% were male and 46% were female with a mean age of 44.1 years. Most (65%) patients consider the extender's training background when choosing a hand surgeon, with 31% of all patients considering PAs to have higher training than NPs and 17% the reverse. Patients responded that certain services should be physician-provided, including determining the need for advanced imaging (eg, magnetic resonance imaging), follow-up for abnormal diagnostics, and new patient visits. Patients were amenable to services being extender-provided, including minor in-office procedures, preoperative teaching, and postoperative clinic visits. Patients lacked a consensus toward reimbursement equity for hand surgeons and physician extenders providing the same clinical services. CONCLUSIONS Our data suggest that patients presenting to a hand surgeon are comfortable receiving direct care from a physician extender in many, but not all, circumstances. Hand surgeons can use these data when deciding how to use extenders to optimize patient satisfaction and practice efficiency as health care systems become increasingly consumer-focused and value-based.

Abstract
Hand infections are common in all patient populations. However, because of variability in presentation and severity, they can be challenging to correctly diagnose and complex to manage. It is important to be aware of special populations such as children, individuals who are immunocompromised, those with diabetes, and intravenous drug users who may have uncommon pathogens or unusual types of infection. Atypical or rare bacterial and fungal infections, even in an immunocompetent host, can be equally challenging to manage. In each of these scenarios, it is critical to be familiar with associated conditions to avoid mismanagement and initiate an appropriate team-based approach for care involving surgery and consultation with an infectious disease specialist.

Abstract
BACKGROUND We report the long-term results of a cohort of patients after radial head replacement with a bipolar design and a smooth cementless stem at a mean follow-up of 10.4 years. METHODS Of 17 possible patients from a previous minimum 2-year follow-up study, 16 were available for review. Patients were assessed using clinical and radiographic examination and with standardized outcome measures. Range of motion, stability, and radiographic evaluation of implant loosening and joint degeneration were assessed. Comparisons were performed using the Wilcoxon signed rank test for unequal groups. RESULTS The average follow-up was 10.5 years (range, 8.5-12 years). The median visual analog scale was 1 (range, 0-5), Minnesota Elbow Performance Index was 93 (range, 70-100), and the Disabilities of the Arm, Shoulder and Hand was 7.5 (range, 0-53). Range of motion was decreased on the operative side compared with the nonoperative side for flexion/extension (P = .005) and pronation/supination (P = .015). Grip strength was decreased on the affected side (P = .045). No patients had elbow instability. Significant arthritic changes developed in 2 patients at the ulnohumeral joint. The median cantilever quotient was 0.4 (range, 0.30-0.50). Osteolysis in zones 1 to 7 was found in all but 2 patients. The median stem radiolucency was 0.5 mm (range, 0.2-0.9 mm). No reoperations occurred since our previous report. Implant survival in this cohort was 97%. CONCLUSION Bipolar radial head prosthesis with a smooth cementless stem effectively restores elbow stability and function after comminuted radial head fractures with or without concomitant elbow instability. Our study demonstrates excellent long-term implant survival.

Abstract
The purpose of this study was to measure the radiographic parameters of proximal pole scaphoid fractures, and calculate the ideal starting points and trajectories for antegrade screw insertion. Computed tomography scans of 19 consecutive patients with proximal pole fractures were studied using open source digital imaging and communications in medicine (DICOM) imaging measurement software. For scaphoid sagittal measurements, fracture inclination was measured with respect to the scaphoid axis. The ideal starting point for a screw in the proximal pole fragment was then identified on the scaphoid sagittal image that demonstrated the largest dimensions of the proximal pole, and hence the greatest screw thread purchase. Measurements were then taken for a standard screw trajectory in the axis of the scaphoid, and a trajectory that was perpendicular to the fracture line. The fracture inclination in the scaphoid sagittal plane was 25 (SD10) °, lying from proximal palmar to dorsal distal. The fracture inclination in the coronal plane was 9 (SD16) °, angling distal radial to proximal ulnar with reference to the coronal axis of the scaphoid. Using an ideal starting point that maximized the thread purchase in the proximal pole, we measured a maximum screw length of 20 (SD 2) mm when using a screw trajectory that was perpendicular to the fracture line. This was quite different from the same measurements taken in a trajectory in the axis of the scaphoid. We also identified a mean distance of approximately 10 mm from the dorsal fracture line to the ideal starting point. A precise understanding of this anatomy is critical when treating proximal pole scaphoid fractures surgically.

Abstract
UNLABELLED We present 20 patients with established proximal pole scaphoid nonunions treated with curettage and cancellous autograft from the distal radius and screw fixation. Fractures with significant proximal pole fragmentation were excluded. Patients were treated at a mean of 26 weeks after injury (range 12-72). Union occurred in 18 of 20 patients (90%) based on computed tomographic imaging. The two nonunions that did not heal were treated with repeat curettage and debridement and iliac crest bone grafting without revision of fixation. Union was achieved in both at a mean of 11 weeks after the revision procedures. Our findings suggest that non-vascularized cancellous autograft and antegrade fixation is a useful option for the treatment of proximal pole scaphoid nonunions. LEVEL OF EVIDENCE IV.

Abstract
Neutrophil extracellular traps (NETs) are critical for the clearance of large pathogens and are also implicated in thrombosis, autoimmunity, and cancer. In this issue of Developmental Cell, Amulic et al. (2017) show that the terminally differentiated, non-cycling neutrophils repurpose cell-cycle proteins and pathways to form NETs.

Abstract
Neutrophils, the most abundant type of leukocytes in blood, can form neutrophil extracellular traps (NETs). These are pathogen-trapping structures generated by expulsion of the neutrophil's DNA with associated proteolytic enzymes. NETs produced by infection can promote cancer metastasis. We show that metastatic breast cancer cells can induce neutrophils to form metastasis-supporting NETs in the absence of infection. Using intravital imaging, we observed NET-like structures around metastatic 4T1 cancer cells that had reached the lungs of mice. We also found NETs in clinical samples of triple-negative human breast cancer. The formation of NETs stimulated the invasion and migration of breast cancer cells in vitro. Inhibiting NET formation or digesting NETs with deoxyribonuclease I (DNase I) blocked these processes. Treatment with NET-digesting, DNase I-coated nanoparticles markedly reduced lung metastases in mice. Our data suggest that induction of NETs by cancer cells is a previously unidentified metastasis-promoting tumor-host interaction and a potential therapeutic target.

Abstract
Introduction The pedicled medial gastrocnemius flap provides a robust coverage option for most soft-tissue deficiencies over the distal anterior aspect of the knee encountered in the setting of an infection after total knee arthroplasty. Indications & Contraindications Step 1 Patient Positioning Position the patient supine with an ipsilateral sterile thigh tourniquet to allow room for harvest of a split-thickness skin graft as needed. Step 2 Revision Arthroplasty for Infection Perform the arthroplasty to address the underlying deep infection (e.g., irrigation and debridement with exchange of modular components, component removal with antibiotic spacer placement, antibiotic spacer exchange, or second-stage reimplantation) prior to the medial gastrocnemius flap that is utilized for soft-tissue coverage. Step 3 Incision and Approach for the Medial Gastrocnemius Flap Use one of two different surgical approaches for the exposure and elevation of the medial gastrocnemius muscle and the identification of its vascular pedicle: the medial approach or the posterior midline approach. Step 4 Elevation of the Medial Gastrocnemius Flap Protect the sural artery pedicle in the popliteal fossa because it is key to raising a viable medial gastrocnemius flap. Step 5 Transposition and Insetting of the Flap Over the Defect Rotate the flap and transpose it anteriorly over the defect either through a subcutaneous tunnel or by dividing the intervening skin bridge. Step 6 Closure Skin-Grafting and Dressing Application Complete the layered skin closure and place a split-thickness skin graft over the remaining exposed muscle flap and a nonadherent compressive bolster dressing or negative-pressure device over the skin graft to prevent hematoma under the skin graft. Step 7 Postoperative Care Progress range of motion of the knee once the flap and graft show evidence of survival, while an appropriate antibiotic regimen is completed. Results We recently reported the largest English-language series, to our knowledge, of medial gastrocnemius flaps performed for soft-tissue coverage in the course of treatment for infection after total knee arthroplasty13.

Abstract
Primary synovial chondromatosis is a rare, benign, proliferative disease of hyaline cartilaginous bodies within the synovium of joints. We report a rare case of primary synovial chondromatosis diffusely affecting the ulnohumeral joint causing pain and motion limitations with extrusion into the cubital tunnel and compressing the ulnar nerve but without any preoperative signs or symptoms of ulnar nerve compression. The patient was successfully treated with an open synovectomy to limit disease progression and improve motion. This case highlights that synovial conditions of the elbow may involve the ulnar nerve even when a patient is asymptomatic. Preoperative use of magnetic resonance imaging of the elbow should be considered in patients undergoing either an open or arthroscopic synovectomy.

Abstract
Enthesopathy of the extensor carpi radialis brevis, often referred to as "tennis elbow," is common and responds to nonsurgical treatment in 80% to 90% of patients within 1 year. For those who proceed with surgery, much remains unclear regarding the ideal treatment. This paper discusses controversies in surgical management of extensor carpi radialis brevis enthesopathy including clinical outcomes of open versus arthroscopic techniques, the relevance of concomitant pathology addressed arthroscopically, and avenues for assessing comparative cost data.

Abstract
There exists a range of surgical and non-surgical approaches to the treatment of both acute and chronic tendon injuries. Despite surgical advances in the management of acute tears and increasing treatment options for tendinopathies, strategies frequently are unsuccessful, due to impaired mechanical properties of the treated tendon and/or a deficiency in progenitor cell activities. Hence, there is an urgent need for effective therapeutic strategies to augment intrinsic and/or surgical repair. Such approaches can benefit both tendinopathies and tendon tears which, due to their severity, appear to be irreversible or irreparable. Biologic therapies include the utilization of scaffolds as well as gene, growth factor, and cell delivery. These treatment modalities aim to provide mechanical durability or augment the biologic healing potential of the repaired tissue. Here, we review the emerging concepts and scientific evidence which provide a rationale for tissue engineering and regeneration strategies as well as discuss the clinical translation of recent innovations.

Abstract
With advances in surgical instrumentation and techniques, as well as expanding surgical indications, wrist arthroscopy is now being used to treat a variety of conditions previously managed only with open techniques. Triangular fibrocartilage complex (TFCC) injuries remain among the most common causes of ulnar-sided wrist pain and can result from both acute and chronic mechanisms of injury. The most common mechanism of acute injury to the TFCC is a fall onto an outstretched hand with the wrist in a supinated, extended position. In patients with unrelenting pain, swelling, or mechanical symptoms despite a concerted effort at nonoperative management, which often consists of bracing, therapy, or injections, surgical intervention is often indicated. Treatment historically consisted of open exploration and repair; however, recently, arthroscopic-assisted and all-arthroscopic techniques have been described. We describe a safe, reproducible, and reliable surgical technique for arthroscopic-assisted outside-in repair of peripheral TFCC tears. In addition, a specific focus on surgical anatomy, including pearls and pitfalls for protecting the dorsal sensory branch of the ulnar nerve, is presented.

Abstract
We conducted a systematic review of studies reporting clinical outcomes after proximal row carpectomy or to four-corner arthrodesis for scaphoid non-union advanced collapse or scapholunate advanced collapse arthritis. Seven studies (Levels I-III; 240 patients, 242 wrists) were evaluated. Significantly different post-operative values were as follows for four-corner arthrodesis versus proximal row carpectomy groups: wrist extension, 39 (SD 11º) versus 43 (SD 11º); wrist flexion, 32 (SD 10º) versus 36 (SD 11º); flexion-extension arc, 62 (SD 14º) versus 75 (SD 10º); radial deviation, 14 (SD 5º) versus 10 (SD 5º); hand grip strength as a percentage of contralateral side, 74% (SD 13) versus 67% (SD 16); overall complication rate, 29% versus 14%. The most common post-operative complications were non-union (grouped incidence, 7%) after four-corner arthrodesis and synovitis and clinically significant oedema (3.1%) after proximal row carpectomy. Radial deviation and post-operative hand grip strength (as a percentage of the contralateral side) were significantly better after four-corner arthrodesis. Four-corner arthrodesis gave significantly greater post-operative radial deviation and grip strength as a percentage of the opposite side. Wrist flexion, extension, and the flexion-extension arc were better after proximal row carpectomy, which also had a lower overall complication rate.

Abstract
BACKGROUND A giant cell tumor is a benign locally aggressive tumor commonly seen in the distal radius with reported recurrence rates higher than tumors at other sites. The dilemma for the treating surgeon is deciding whether intralesional treatment is adequate compared with resection of the primary tumor for oncologic and functional outcomes. More information would be helpful to guide shared decision-making. QUESTIONS/PURPOSES We asked: (1) How will validated functional scores, ROM, and strength differ between resection versus intralesional excision for a giant cell tumor of the distal radius? (2) How will recurrence rate and reoperation differ between these types of treatments? (3) What are the complications resulting in reoperation after intralesional excision and resection procedures? (4) Is there a difference in functional outcome in treating a primary versus recurrent giant cell tumor with a resection arthrodesis? METHODS Between 1985 and 2008, 39 patients (39 wrists) were treated for primary giant cell tumor of the distal radius at two academic centers. Twenty patients underwent primary intralesional excision, typically in cases where bony architecture and cortical thickness were preserved, 15 underwent resection with radiocarpal arthrodesis, and four had resection with osteoarticular allograft. Resection regardless of reconstruction type was favored in cases with marked cortical expansion. A specific evaluation for purposes of the study with radiographs, ROM, grip strength, and pain and functional scores was performed at a minimum of 1 year for 21 patients (54%) and an additional 11 patients (28%) were available only by phone. We also assessed reoperations for recurrence and other complications via chart review. RESULTS With the numbers available, there were no differences in pain or functional scores or grip strength between groups; however, there was greater supination in the intralesional excision group (p=0.037). Tumors recurred in six of 17 wrists after intralesional excision and none of the 15 after en bloc resection (p=0.030). There was no relationship between tumor grade and recurrence. There were 12 reoperations in eight of 17 patients in the intralesional excision group but only one of 11 patients (p=0.049) who underwent resection arthrodesis with distal radius allograft had a reoperation. There were no differences in functional scores whether resection arthrodesis was performed as the primary procedure or to treat recurrence after intralesional excision. CONCLUSIONS Resection for giant cell tumor of the distal radius with distal radius allograft arthrodesis showed a lower recurrence rate, lower reoperation rate, and no apparent differences in functional outcome compared with joint salvage with intralesional excision. Because an arthrodesis for recurrence after intralesional procedures seems to function well, we believe that intralesional excision is reasonable to consider for initial treatment, but the patient should be informed about the relative benefits and risks of both options during the shared decision-making process. Because arthrodesis after recurrence functions similar to the initial resection and arthrodesis, an initial treatment with curettage remains a viable, and likely the standard, mode of treatment for most giant cell tumors of the distal radius unless there is extensive bone loss. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Hand surgeons are frequently challenged by the unique requirements of soft tissue coverage of the hand. Whereas many smaller soft tissue defects without involvement of deep structures are amenable to healing by secondary intention or skin grafting, larger lesions and those with exposed tendon, bone, or joint often require vascularized coverage that allows rapid healing without wound contraction. The purpose of this review was to present an overview of local and regional flaps commonly used for soft tissue reconstruction within the hand.

Abstract
BACKGROUND There is little comparative data to guide implant choice for radial head replacements. The purpose of this study was to evaluate the clinical and radiographic results between patients who received a smooth-stemmed bipolar radial head implant and patients who received an in-growth monopolar prosthesis. METHODS Twenty-seven patients requiring a metallic radial head implant in the management of acute or chronic elbow trauma were evaluated. Fourteen patients received a smooth-stemmed bipolar prosthesis and 13 patients received a press-fit monopolar prosthesis. Patients returned for follow-up at an average of 33 months (range, 18-57). Outcome assessments included joint motion, elbow stability, grip strength, pain, the Mayo Elbow Performance Index, and the Disability of Arm, Shoulder and Hand questionnaire. Radiographs were reviewed for joint congruence, ectopic bone, periprosthetic osteolysis, degenerative arthritis, and capitellar wear, and selected patients were tested for inflammatory markers and metal ion levels. RESULTS The differences between patient groups for elbow flexion and forearm pronation averaged 10° or less. There were no other pertinent differences between groups for standardized patient and examiner-determined outcomes. There was a trend for ectopic bone to develop more commonly around the smooth-stemmed implants, while periprosthetic osteolysis was more pronounced in cases with the press-fit design. Inflammatory markers were normal, and metal ion levels did not exceed values reported for a well-functioning hip arthroplasty. CONCLUSION Outcomes at short- to mid-term follow-up were similar with either implant design. Loosening of a press-fit prosthesis may lead to extensive osteolysis, but of undetermined clinical consequence.

Abstract
Radioscapholunate arthrodesis is performed for patients who experience pain and disability from radiocarpal arthritis. Initial reports from the 1980s demonstrated high nonunion rates and marginal clinical outcomes. Improvements in surgical technique and clearly defined indications have reduced nonunion rates and improved patient satisfaction. We present a technique using headless compression screws inserted through a dorsal approach, which optimizes hardware placement and incorporates local bone graft harvested from the insertion site to supplement the arthrodesis.

Abstract
Tendinopathy is a widespread and disabling condition characterized by collagen fiber disruption and accumulation of a glycosaminoglycan-rich chondroid matrix. Recent clinical reports have illustrated the potential of mechanical loading (exercise) therapies to successfully treat chronic tendinopathies. We have developed a new murine tendinopathy model which requires a single injection of TGF-β1 into the Achilles tendon midsubstance followed by normal cage activity for 2 weeks. At this time, tendon maximum stress showed a dramatic (66%) reduction relative to that of normal controls and this persisted at four weeks. Loss of material properties was accompanied by abundant chondroid cells within the tendon (closely resembling the changes observed in human samples obtained intra-operatively) and increased expression of Acan, Col1a1, Col2a1, Col3a1, Fn1 and Mmp3. Mice subjected to two weeks of daily treadmill exercise following TGF-β1 injection showed a similar reduction in tendon material properties as the caged group. However, in mice subjected to 4 weeks of treadmill exercise, tendon maximum stress values were similar to those of naive controls. Tendons from the mice exercised for 4 weeks showed essentially no chondroid cells and the expression of Acan, Col1a1, Col2a1, Col3a1, and Mmp3 was significantly reduced relative to the 4-week cage group. This technically simple murine tendinopathy model is highly amenable to detailed mechanistic and translational studies of the biomechanical and cell biological pathways, that could be targeted to enhance healing of tendinopathy.

Abstract
PURPOSE We describe a variant of triangular fibrocartilage complex (TFCC) tears in which the superficial fibers attaching to the ulnar capsule are torn, with preservation of deep fibers inserting on the fovea. We present the clinical and magnetic resonance imaging findings and the results of arthroscopic repair in patients with this injury. METHODS Twenty-nine wrists were treated arthroscopically for peripheral TFCC tears with outside-in suture repair of the TFCC to the ulnar capsule. A retrospective review of all cases was performed to assess the physical examination, magnetic resonance imaging, and intraoperative findings. Patients were evaluated at greater than 1 year with range of motion, grip strength, standard outcome measures, and a survey assessing return to work and sports. RESULTS Before surgery, all patients had complaints of ulnar-sided wrist pain with a stable distal radioulnar joint on examination. Twenty-six wrists (90%) were available for follow-up at a mean of 31 months. There was one repeat surgery, a re-tear that required revision TFCC repair. The preoperative visual analog scale and Disabilities of the Arm, Shoulder, and Hand scores improved from 5 and 38 to 1 and 9, respectively, at final follow-up. Side-to-side comparisons demonstrated no measurable loss in motion or grip strength. There were no cases of distal radioulnar joint instability at final follow-up. Of 11 high-level athletes in the total cohort, 7 (64%) were able to return to sports, including all of those in racquet sports; however, athletes who bore weight through their hands were unable to return to their sporting activity. CONCLUSIONS Tears of the TFCC superficial fibers with the deep fibers intact present with ulnar-sided wrist pain but without distal radioulnar joint instability. The results of outside-in repair of the articular disk back to the ulnar capsule demonstrated improvement in pain and function with no measurable objective losses. Return to sport was variable and appeared worse for those who bear weight through the hands.

Abstract
Heterotopic ossification (HO) is a common complication of elbow trauma or surgery. HO can impair joint function; when it does, surgical removal is required. Radiotherapy (RT) prevents HO formation in the hip. However, few data exist on the efficacy of RT in preventing HO formation in the elbow. We retrospectively analyzed the outcomes of elbow surgery followed by prophylactic single-fraction RT and use of nonsteroidal anti-inflammatory drugs (NSAIDs). All patients had ectopic bone resected at surgery or significant risk factors for development of ectopic bone. Of the 52 patients who underwent RT after high-risk elbow surgery, 44 had postoperative radiographs of the treated elbow available for evaluation. At a median follow-up of 136 days, 21 patients (48%) had radiographic evidence of HO. In all cases, however, the HO was small and not functionally significant. No complications were attributed to RT use. This retrospective review represents the largest published series of patients who have undergone postoperative RT to prevent HO formation in the elbow. Our findings support the idea that RT, in combination with NSAID use, is safe and efficacious in preventing development of clinically significant HO in the elbow.

Abstract
PURPOSE The purpose of this study was to investigate whether ambulatory surgery centers can deliver lower-cost care and to identify sources of those cost savings. METHODS We performed a cost identification analysis of outpatient volar plating for closed distal radius fractures at a single academic medical center. Multiple costs and time measures were taken from an internal database of 130 consecutive patients and were compared by venue of treatment, either an inpatient facility or an ambulatory, stand-alone surgery facility. The relationships between total cost and operative time and multiple variables, including fracture severity, patient age, gender, comorbidities, use of bone graft, concurrent carpal tunnel release, and surgeon experience, were examined, using multivariate analysis and regression modeling to identify other cost drivers or explanatory variables. RESULTS The mean operative cost was considerably greater at the inpatient facility ($7,640) than at the outpatient facility ($5,220). Cost drivers of this difference were anesthesia services, post-anesthesia care unit, and operating room costs. Total surgical time, nursing time, set-up, and operative times were 33%, 109%, 105%, and 35% longer, respectively, at the inpatient facility. There was no significant difference between facilities for the additional variables, and none of those variables independently affected cost or operative time. CONCLUSIONS The only predictor of cost and time was facility type. This study supports the use of ambulatory stand-alone surgical facilities to achieve efficient resource utilization in the operative treatment of distal radius fractures. We also identified several specific costs and time measurements that differed between facilities, which can serve as potential targets for tertiary facilities to improve utilization.

Abstract
The identity of higher-order neurons and circuits playing an associative role to control feeding is unknown. We injected pseudorabies virus, a retrograde tracer, into masseter muscle, salivary gland, and tongue of BAC-transgenic mice expressing GFP in specific neural populations and identified several CNS regions that project multisynaptically to the periphery. MCH and orexin neurons were identified in the lateral hypothalamus, and Nurr1 and Cnr1 in the amygdala and insular/rhinal cortices. Cholera toxin β tracing showed that insular Nurr1(+) and Cnr1(+) neurons project to the amygdala or lateral hypothalamus, respectively. Finally, we show that cortical Cnr1(+) neurons show increased Cnr1 mRNA and c-Fos expression after fasting, consistent with a possible role for Cnr1(+) neurons in feeding. Overall, these studies define a general approach for identifying specific molecular markers for neurons in complex neural circuits. These markers now provide a means for functional studies of specific neuronal populations in feeding or other complex behaviors.

Abstract
PURPOSE The use of a pedicled flexor carpi ulnaris (FCU) muscle proximal turnover flap has been described previously for soft tissue reconstruction at the posterior elbow. Whereas consistent arterial supply to the FCU has been reported, the reliability of distal flap perfusion has not been confirmed. This study evaluated the vascular perfusion of an FCU turnover flap, based on the most proximal primary vascular pedicle that would permit a proximal turnover flap reconstruction to include the olecranon tip. METHODS In 12 fresh-frozen, proximal humeral human amputation specimens, the FCU flap was elevated from distal to proximal, preserving the most proximal primary vascular pedicle to the muscle belly that would permit flap coverage of the olecranon tip. The axillary artery was injected with India ink after ligation of radial and ulnar arteries at the wrist. After injection, each specimen was sectioned transversely at 0.5-cm increments to assess vascular perfusion of the muscle using loupe magnification. RESULTS The distance from the olecranon tip to the distal FCU muscle belly was 25.9 cm. The primary vascular pedicle that would facilitate creation of a proximal turnover flap was, on average, 5.9 cm distal to the olecranon tip. Perfusion of FCU muscle as measured distal to this primary pedicle was present in 50% to 100% of the muscle belly at an average of 8.9 cm beyond the pedicle. Perfusion of 25% to 50% of the FCU muscle belly was present at an average of 11.1 cm beyond the pedicle. Perfusion became less consistent (<25%) within the muscle belly at an average distance of 11.6 cm. CONCLUSIONS Use of a proximally based, pedicled FCU muscle turnover flap provides a reliable option for soft tissue reconstruction at the posterior elbow. We observed consistent arterial perfusion of the muscle flap when preserving a proximal vascular pedicle 5.9 cm distal to the olecranon tip.
