Abstract
The association of radial nerve palsy and humeral shaft fracture is well known. Primary exploration and fracture fixation is recommended for open fractures and vascular injury while expectant management remains the standard of care for closed injuries. In the absence of nerve recovery, exploration and reconstruction is recommended 3 to 5 months following injury. When direct repair or nerve grafting is unlikely to achieve a suitable outcome, nerve and tendon transfers are potential options for the restoration of wrist and finger extension.

Abstract
BACKGROUND The US health care system is the second largest contributor of trash. Approximately 20% to 70% of waste is produced by operating rooms, and very few of this waste is recycled. The purpose of this study is to quantify the opened but unused disposable supplies and generate strategies to reduce disposable waste. METHODS A single-center prospective study to evaluate the cost of opened but unused single-use operating room supplies was completed by counting the number of wasted disposable products at the end of hand surgery cases. We used χ2 test, t test, Wilcoxon rank-sum test, and simple linear regression to assess the associations between patient and case variables and the total cost of wasted items. Environmentally Extended Input Output Life Cycle Assessment methods were used to convert the dollar spent to kilograms of carbon dioxide equivalent (CO2-e), a measure of greenhouse gas emissions. RESULTS Surgical and dressing items that were disposed of and not used during each case were recorded. We included 85 consecutive cases in the analysis from a single surgeon's practice. Higher cost from wasted items was associated with shorter operative time (P = .010). On average, 11.5 items were wasted per case (SD: 3.6 items), with a total of 981 items wasted over the 85 cases in the study period. Surgical sponges and blades were 2 of the most unused items. Wasted items amounted to a total of $2193.5 and 441 kg of CO2-e during the study period. CONCLUSIONS This study highlights the excessive waste of unused disposable products during hand surgery cases and identifies ways of improvement.

Abstract
PURPOSE The objective of this study was to investigate and describe the presence of osteolysis after implantation of polyetheretherketone (PEEK) suture anchors in the hand and wrist. METHODS Patients who underwent hand or wrist surgery using PEEK suture anchor(s) at a large academic institution from January 2019 to January 2021 were identified. Patients without accessible intraoperative fluoroscopic imaging were excluded. Patient demographics, type of procedure, and suture anchor material were recorded. The suture anchor tunnel size was measured on sequential radiographs and recorded as percentage change. Descriptive statistics were used to summarize findings. RESULTS A total of 26 PEEK suture anchors in 14 patients were included, with an average follow-up of 12.0 months (range, 1.5-24.1 months). Twenty-seven percent of the anchors (7/26) demonstrated osteolysis at final follow-up, as defined by enlargement of tunnel size by >30%. In all anchors, the tunnel size increased by 19.1% on average (range, -7.7% to 56.1%) by final follow-up. CONCLUSIONS Polyetheretherketone suture anchors may be associated with the development of osteolysis in hand and wrist surgery. The clinical implications of osteolysis in the smaller bones of the hand and wrist remain unclear. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
Background Pneumatic tourniquets are widely used in hand surgery. Elevated pressures can be associated with complications, and thus, guidelines based on patient-specific tourniquet pressures have been recommended. The primary aim of this study was to determine whether lower tourniquet values based on systolic blood pressure (SBP) could be effectively applied in upper extremity surgery. Methods A prospective case series of 107 consecutive patients undergoing upper extremity surgery with use of a pneumatic tourniquet was performed. Tourniquet pressure used was based on the patient's SBP. The tourniquet was inflated based on our predetermined guidelines: 60 mm Hg was added for SBP < 130 mm Hg, 80 mm Hg for SBP between 131 and 190 mm Hg, and 100 mm Hg for SBP > 191 mm Hg. The outcome measures included intraoperative tourniquet adjustment, surgeon-rated quality of bloodless operative field and complications. Results The mean tourniquet pressure was 183 ± 26 mm Hg with a mean tourniquet time of 34 minutes (range: 2-120 minutes). There were no instances of intraoperative tourniquet adjustment. The surgeon-rated quality of bloodless operative field was excellent in all patients. No complications were associated with the use of a tourniquet. Conclusion Tourniquet inflation pressure based on SBP is an effective method to provide a bloodless surgical field in upper extremity surgery at significantly lower inflation pressures than are the current standards.

Abstract
BACKGROUND Handwritten consent forms for medical treatment are commonly used despite the associated risk of documentation errors. We performed an internal audit of handwritten surgical consent forms to assess the quality of consenting practices within the department of hand surgery at our orthopedic specialty hospital. METHODS A sample of 1,800 charts was selected. Con- sents were assessed for procedure type, physician details, abbreviations, consistency, and legibility. RESULTS A total of 1,309 charts met the inclusion crite- ria. Two hundred and eight consents contained at least one illegible word. The name of the consenting physician was not listed or illegible on 114 forms. Medical abbreviations were found on 1.8% of all included forms, and 19 consent forms contained a crossed-out word or correction. CONCLUSIONS Although the majority of the handwrit- ten consent forms were complete, accurate, and legible, there were notable errors in the consenting process at our institution. Documentation errors have medical and ethical ramifications. Further research into consenting practices is necessary to improve the quality of consent forms and the process of informed consent.

Abstract
Osteochondromas are common benign bone tumors that are most commonly found in children and adolescents. They are usually slow-growing and located at the metaphysis of the long bones. When present in adults in atypical locations or with concerning features, such as thickened cartilage cap and rapid growth, osteochondromas warrant imaging to assess the risk of malignant transformation into chondrosar- coma and may require surgical excision. Here, we describe the unusual case of an adult male with a rapidly growing osteochondroma of the proximal phalanx that subsequently underwent surgical excision.

Abstract
INTRODUCTION Overprescribing contributes to the misuse and overuse of narcotics. We hypothesized that implementation of postoperative prescribing guidelines would consistently reduce the amount of opioids prescribed after ambulatory hand surgery. METHODS A divisional protocol was instituted in November 2018. A retrospective cohort study was designed to examine the policy's effects on postoperative prescribing. Postoperative opioid prescriptions for patients undergoing ambulatory hand surgery were evaluated 1 year before and 1 year after policy initiation. All prescriptions were converted into the total oral morphine equivalent (OME) prescribed. RESULTS A total of 1,672 surgeries were included. Six hundred sixty-one cases were in preimplementation group, and 1,011 cases were in the postimplementation group. The median of total OME decreased significantly after distribution of prescribing guidelines from 75 in the preimplementation group to 45 in the postimplementation group (p < .001) with significant reductions seen for carpal tunnel release (p < .001), trigger finger release (p < .001), distal radius open reduction internal fixation (p < .001), and finger closed reduction and pinning (p < .001). When categorized by procedure type, the median of total OME decreased from 75 to 30 for soft tissue procedures (p < .001) and from 120 to 100 for bony procedures (p < .001). CONCLUSION Divisional prescribing guidelines lead to consistent short-term to mid-term reductions in the amount of opioid medication prescribed postoperatively.

Abstract
Background: A major consequence of the COVID-19 pandemic on the U.S. healthcare system has been the rapid transition away from in-person healthcare visits to telehealth. This study analyzed patient and surgeon satisfaction in the utilization of telehealth within the hand surgery division during the COVID-19 pandemic. Methods: All hand surgery patients who completed a telemedicine visit from March 30th, 2020 through April 30th, 2020 completed a 14-question survey via e-mail. Hand surgeons who participated in telemedicine completed a separate 14-question survey. Survey results were presented descriptively (mean ± standard deviation) and patient factors influencing satisfaction were determined using univariate and multivariate proportional modeling. Results: 89 patients and five surgeons completed the surveys. Patients were very satisfied with their telemedicine visits (4.21/5.00 ± 0.89). Multivariate proportional modeling determined patients who found it "very easy" (5/5) to arrange telemedicine visits had greater satisfaction (OR = 4.928; 95% CI = 0.94 to 25.84) compared to those who found it "difficult" (2/5) (p = 0.059). Patients who believed they could ask/relay questions/concerns "extremely effectively" (5/5) had greater satisfaction (OR = 55.236; CI = 11.39 to 267.80) compared to those who asked/relayed questions only "slightly effective" to "moderately effectively" (p < 0.001). Surgeons were similarly satisfied with their telemedicine experience (4.00/5.00 ± 0.89) and were confident in their diagnoses (4.20/5.00 ± 0.84). All surgeons responded they will continue using telemedicine. 30.7% of patients would choose telemedicine over an inperson visit. Conclusions: Telemedicine provides a viable platform for healthcare delivery with high patient and surgeon satisfaction. Most patients still prefer in-person visits for the post-pandemic future.

Abstract
Ultrasonography as a diagnostic and therapeutic tool has become a resource for musculoskeletal injuries. It can be a useful imaging modality for clinical correlation of physical examination findings as well as an aid for image-guided procedures. Understanding the settings in which it is a helpful adjunct will have implications on efficiency and cost utility. The objectives of this chapter are to provide a background of ultrasonography as a musculoskeletal imaging modality, provide clinical correlation for ultrasonographic findings for common upper extremity pathology, review the diagnostic efficacy of ultrasonography for image-guided procedures, and provide insight into the cost utility of ultrasonography guidance for therapeutic injections.

Abstract
PURPOSE Wide-awake local anesthesia no tourniquet (WALANT) is an increasingly popular surgical technique. However, owing to surgeon preference, patient factors, or hospital guidelines, it may not be feasible to inject patients with solutions containing epinephrine the recommended 25 minutes prior to incision. The purpose of this study was to assess pain and patient experience after short hand surgeries done under local anesthesia using a tourniquet rather than epinephrine for hemostasis. METHODS Ninety-six consecutive patients undergoing short hand procedures using only local anesthesia and a tourniquet (LA-T) were assessed before and after surgery. A high arm pneumatic tourniquet was used in 73 patients and a forearm pneumatic tourniquet was used in 23. All patients received a local, unbuffered plain lidocaine injection. No patients received sedation. Pain related to local anesthesia, pneumatic tourniquet, and the procedure was assessed using a visual analog scale (VAS). Patient experience was assessed using a study-specific questionnaire based on previous WALANT studies. Tourniquet times were recorded. RESULTS Mean pain related to anesthetic injection was rated 3.9 out of 10. Mean tourniquet related pain was 2.9 out of 10 for high arm pneumatic tourniquets and 2.3 out of 10 for forearm pneumatic tourniquets. Patients rated their experience with LA-T favorably and 95 of 96 patients (99%) reported that they would choose LA-T again for an equivalent procedure. Mean tourniquet time was 9.6 minutes and only 1 patient had a tourniquet inflated for more than 20 minutes. Tourniquet times less than 10 minutes were associated with less pain than tourniquet times greater than 10 minutes (P < .05); however, both groups reported the tourniquet to be on average less painful than the local anesthetic injection. CONCLUSION Short wide-awake procedures using a tourniquet are feasible and well accepted. Local anesthetic injection was reported to be more painful than pneumatic tourniquet use. Tourniquets for short wide-awake procedures can be used in settings in which preprocedure epinephrine injections are logistically difficult or based on surgeon preference.

Abstract
Background: Previous work evaluating the pronator quadratus (PQ) muscle following volar plate fixation (VPF) of distal radius fractures (DRF) suggests that PQ repair often fails in the postoperative period. The purpose of this investigation was to assess PQ repair integrity following VPF of DRF using dynamic musculoskeletal ultrasonography. Methods: Twenty adult patients who underwent VPF of DRF with repair of the PQ with a minimum follow-up of 3 months underwent bilateral dynamic wrist ultrasonography. The integrity of the PQ repair, wrist range of motion (ROM) and strength, and functional outcome scores were assessed. Results: Mean patient age at the time of surgery was 59 ± 14 years, and 50% underwent VPF of their dominant wrist. Patients were evaluated at a mean 9 ± 4 months after VPF. All patients had an intact PQ repair. The volar plate was completely covered by the PQ in 55% of patients and was associated with a larger PQ when compared to patients with an incompletely covered volar plate (P = .026). The flexor pollicis longus tendon was in contact with the volar plate in 20% of patients, with those patients demonstrating a trend toward significantly increased wrist flexion (P = .053). No difference in ROM, strength, or outcome scores was noted among wrists with completely or incompletely covered volar plates. Conclusions: The PQ demonstrates substantial durability after repair following VPF. Wrist ROM, strength, and functional outcomes are similar in wrists in which the volar plate is completely or incompletely covered by the repaired PQ.

Abstract
BACKGROUND Post-traumatic elbow contracture is a debilitating complication after elbow trauma. The purpose of this study was to characterize the affected patient population, operative management, and outcomes after operative elbow contracture release for treatment of post-traumatic elbow contracture. METHODS A retrospective record review was conducted to identify all patients who underwent post-traumatic elbow contracture release performed by 1 of 3 surgeons at one academic medical center. Patient demographics, injuries, operative details, outcomes, and complications were recorded. RESULTS The study included 103 patients who met inclusion criteria. At the time of contracture release, patients were a mean age of 45.2 ± 15.6 years. Contracture release resulted in a significant mean increase to elbow extension/flexion arc of motion of 52° ± 18° (P < .0005). Not including recurrence of contracture, a subsequent complication occurred in 10 patients (10%). Radiographic recurrence of heterotopic ossification (HO) occurred in 14 patients (14%) after release. Ten patients (11%) elected to undergo a secondary operation to gain more motion. CONCLUSION Soft tissue and bony elbow contracture release is effective. Patients with post-traumatic elbow contracture can make significant gains to their arc of motion after contracture release surgery and can expect to recover a functional elbow arc of motion. Patients with severe preoperative contracture may benefit from concomitant ulnar nerve decompression. HO prophylaxis did not affect the rate of HO recurrence or ultimate elbow range of motion. However, patients must be counseled that contracture may reoccur, and some patients may require or elect to have more than one procedure to achieve functional motion.

Abstract
BACKGROUND Fracture of the metaphyseal region of the distal ulna is an uncommon injury that has been reported to occur concomitantly with distal radius fracture. We aimed to report the incidence and types of distal ulnar head and neck fractures associated with distal radius fractures and compare outcomes in operatively versus non-operatively treated patients. METHODS Over a 5-year period a distal radius fracture registry was maintained at our institution. Eleven of 512 consecutive patients had metaphyseal distal ulna fractures in association with distal radius fractures and at least 1-year follow-up. Baseline radiographs and functional data were obtained, and patients were followed at 1-week, 2-week, 3-week, 6-week, 3-month, 6-month, 1-year, and 2-year intervals. Patients were split into two treatment groups: Group 1 consisted of five non-operatively treated patients, and Group 2 consisted of six operatively treated patients. RESULTS Four separate fracture patterns were observed: simple transverse or oblique fracture of the ulnar neck just proximal to the ulnar head, fracture of the neck region with concomitant fracture of the tip of the ulnar styloid, simple fracture of the ulnar head, and comminuted fracture of the ulnar head. There were no statistical differences between the two groups with regard to flexion, extension, supination, pronation, and functional outcomes. CONCLUSIONS Ulnar fracture patterns observed did not easily fall into previously described categories, and we have proposed a new classification system. Simple fractures of the ulnar neck or head often do not require operative fixation.

Abstract
The management of distal radius fractures has evolved over time from a largely nonoperative paradigm to a more commonly performed operative procedures today. Surgical trends have similarly developed, with dorsal plating falling out of favor due to complications involving extensor tendon pathology as well as due to the ubiquity of the volar plate along with the advent of locking plate technology. However, with the improvement in design of newer generation dorsal plates, this technique should be used in the appropriate clinical situation, including dorsal comminution and angulation with concomitant carpal pathology. Outcome data supports dorsal plating and has been shown to be comparable to that of volar plating, with some unique advantages. As such, the technique of dorsal plating should have a role in surgical management of these injuries.

Abstract
Background: The objective of this study is to determine subclinical changes in hand sensation after brachial plexus blocks used for hand surgery procedures. We used Semmes-Weinstein monofilament testing to detect these changes. We hypothesized that patients undergoing brachial plexus nerve blocks would have postoperative subclinical neuropathy detected by monofilament testing when compared with controls. Methods: In total, 115 hand surgery adult patients were prospectively enrolled in this study. All patients undergoing nerve-related procedures were excluded as well as any patients with preoperative clinically apparent nerve deficits. Eighty-four patients underwent brachial plexus blockade preoperatively, and 31 patients underwent general anesthesia (GA). Semmes-Weinstein monofilament testing of the hand was performed preoperatively on both the operative and nonoperative extremities and postoperatively at a mean of 11 days on both hands. Preoperative and postoperative monofilament testing scores were compared between the block hand and the nonoperated hand of the same patient, as well as between the block hands and the GA-operated hands. Results: There were no recorded clinically relevant neurologic complications in the block group or GA group. A statistically significant decrease in sensation in postoperative testing in the operated block hand compared with the nonoperated hand was noted. When comparing the operated block hand with the operated GA hand, there was a decrease in postoperative sensation in the operated block hand that did not reach statistical significance. Conclusions: Brachial plexus blockade causes subtle subclinical decreases in sensibility at short-term follow-up, without any clinically relevant manifestations.

Abstract
Total wrist arthroplasty (TWA), first performed in the late 19th Century, is still an infrequently used operation. It is most commonly indicated in patients with rheumatoid arthritis who have pan-carpal wrist involvement. It is an alternative to total wrist arthrodesis in patients who wish to preserve joint motion. Patients must lead a low-demand lifestyle and have failed non-operative measures. Complications are not insignificant and have been reported to be as high as 43%. Modern generation implants most often fail due to dislocation or loosening. Because wrist arthrodesis remains the gold standard treatment, particularly in patients with higher physical demands, it remains to be seen whether TWA will gain greater acceptance as prosthetic designs evolve.

Abstract
Background: The purpose of this study was to determine the factors that affect hand surgeon operating room (OR) turnover time. We hypothesized that surgeon presence in the OR, decreased American Society of Anesthesiologists (ASA) class, smaller case type, and earlier case time, as well as other factors, decreased OR turnover time. Methods: A total of 685 hand surgery cases performed by 5 attending hand surgeons between September 2013 and December 2014 were identified. Turnover time, patient comorbidities (ASA class), surgeon, prior OR surgical procedure, current OR surgical procedure, location of the surgery (ambulatory surgical center [ASC] vs orthopedic specialty hospital [OSH]), time of surgery, and order of OR cases were recorded. The effect of surgeon routine variables, OR case factors, and patient health status on OR turnover was analyzed. Results: Turnover time was significantly shorter in cases where the surgeon remained in the OR during turnover (27.5 minutes vs 30.4 minutes) and when the surgeon incentivized OR staff (24 minutes vs 29 minutes). The ASC was found to have shorter turnover times than the OSH (27.9 minutes vs 36.4 minutes). In addition, ASA class, type of prior OR procedure, type of current OR procedure, and case order all significantly affected turnover time. Comparison of OR turnover time among the 5 surgeons revealed a statistically significant difference at the OSH but not at the ASC. Conclusion: OR turnover time is significantly affected by surgeon routine, location of surgery, patient ASA class, procedure type, and case order. Interestingly, the effect of hand surgeon routine on OR turnover time may be amplified at an academic OSH versus an ASC.

Abstract
PURPOSE To assess the risk of injury to the dorsal sensory branch of the ulnar nerve (DSBUN) with percutaneous pinning of commonly stabilized ulnar-sided structures. METHODS Eleven fresh-frozen cadaveric upper extremities were assessed. Percutaneous pinning of the fifth metacarpal base and neck, lunotriquetral joint, ulnar styloid, and distal radioulnar joint (DRUJ) with 1.4-mm Kirschner wires was performed under fluoroscopic guidance. Each specimen was then carefully dissected and the distance from each pin to the DSBUN was measured using a digital caliper. Direct injury to the DSBUN and pins found immediately adjacent to the nerve were recorded. RESULTS Mean distance from the pin to the DSBUN at the fifth metacarpal neck was 5.0 ± 1.5 mm; fifth metacarpal base, 2.3 ± 2.2 mm; lunotriquetral joint, 1.8 ± 1.6 mm; ulnar styloid, 0.8 ± 1.1 mm; and DRUJ, 3.1 ± 0.9 mm. Two of 11 ulnar styloid pins and 1 of 11 lunotriquetral pin directly penetrated the DSBUN, whereas 4 of 11 ulnar styloid pins, 3 of 11 fifth metacarpal base pins, and 2 of 11 lunotriquetral pins were directly adjacent to the DSBUN. There was an increased overall risk of DSBUN injury (risk of direct injury and risk of adjacent pin) with pinning of the ulnar styloid compared with fifth metacarpal neck and DRUJ pinning. CONCLUSIONS The current study demonstrates the risk of iatrogenic injury to the DSBUN with percutaneous pinning of the ulnar styloid, lunotriquetral joint, and fifth metacarpal base. CLINICAL RELEVANCE We recommend identifying and protecting the nerve to mitigate the risk of iatrogenic injury when performing ulnar-sided pinning of structures from the ulnar styloid to the fifth metacarpal base.

Abstract
The literature on the effect of ulnar styloid fractures (USFs) on concomitant distal radius fractures (DRFs) is mixed. We conducted a study to determine if associated ipsilateral USFs affect outcomes of DRFs. We retrospectively evaluated 315 DRFs treated (184 operatively, 131 nonoperatively) over a 7-year period. Concomitant USFs were identified. Mean follow-up was 12 months. Disabilities of the Arm, Shoulder, and Hand (DASH) and 36-Item Short Form Health Survey (SF-36) outcome scores, and grip strength and wrist range of motion data, were collected. Statistical analysis was performed with Student t test and analysis of variance. Incidence of concomitant USF and DRF was higher (P < .0002) in the operative group (64.6%) than in the nonoperative group (39.1%). Patients with USFs had worse mean (SD) pain score, 1.80 (2.43) versus 0.80 (1.55) (P = .0001), DASH score, 17.03 (18.94) versus 9.21 (14.06) (P = .001), and SF-36 score, 77.16 (17.69) versus 82.68 (16.10) (P = .022). In the operative group, patients with USFs had more pain and poorer DASH Functional scores than patients without USFs. Results were similar in the nonoperative group. There was no difference in healing time between intra-articular and extra-articular fractures or between presence and absence of USFs. Concomitant occurrence of USFs and DRFs-which is associated with worse pain scores and lower functioning compared with USFs without DRFs-should prompt clinicians to counsel patients about delayed recovery.

Abstract
BACKGROUND The purpose of this study is to evaluate patient's perceptions of physician reimbursement for the most commonly performed surgery on the hand, a carpal tunnel release (CTR). METHODS Anonymous physician reimbursement surveys were given to patients and non-patients in the waiting rooms of orthopaedic hand physicians' offices and certified hand therapist's offices. The survey consisted of 13 questions. Respondents were asked (1) what they thought a surgeon should be paid to perform a carpal tunnel release, (2) to estimate how much Medicare reimburses the surgeon, and (3) about how health care dollars should be divided among the surgeon, the anesthesiologist, and the hospital or surgery center. Descriptive subject data included age, gender, income, educational background, and insurance type. RESULTS Patients thought that hand surgeons should receive $5030 for performing a CTR and the percentage of health care funds should be distributed primarily to the hand surgeon (56 %), followed by the anesthesiologist (23 %) and then the hospital/surgery center (21 %). They estimated that Medicare reimburses the hand surgeon $2685 for a CTR. Most patients (86 %) stated that Medicare reimbursement was "lower" or "much lower" than what it should be. CONCLUSION Respondents believed that hand surgeons should be reimbursed greater than 12 times the Medicare reimbursement rate of approximately $412 and that the physicians (surgeons and anesthesiologist) should command most of the health care funds allocated to this treatment. This study highlights the discrepancy between patient's perceptions and actual physician reimbursement as it relates to federal health care. Efforts should be made to educate patients on this discrepancy.

Abstract
PURPOSE To determine whether specific anatomic lesions of the scapholunate supporting structures are associated with the grades of scapholunate instability according to the Geissler classification. METHODS Six fresh frozen cadaveric limbs underwent serial arthroscopic sectioning of the scapholunate supporting ligaments. To simulate a progressive scapholunate injury based on the current literature, sectioning occurred as follows: volar scapholunate interosseous ligament (SLIL), membranous SLIL, dorsal SLIL, radioscaphocapitate, long radiolunate, dorsal radiocarpal, dorsal intercarpal, and scaphotrapeziotrapezoid ligaments. We performed arthroscopic examination of the radiocarpal and midcarpal joints after each ligamentous sectioning and recorded the appearance of the scapholunate interval. RESULTS There was a progressive increase in Geissler grade with sequential sectioning of the scapholunate supporting ligaments. In all specimens, Geissler grade 2 injury was associated with sectioning of intrinsic ligaments only. Geissler grade 3 injury first appeared with sectioning through the dorsal SLIL and continued through sectioning of the volar extrinsic ligaments. Geissler grade 4 injury did not occur until the dorsal extrinsic ligaments were sectioned. Statistical analysis indicated a linear relationship between ligament sectioned and Geissler grade, with deeper sections associated with a higher Geissler grade. CONCLUSIONS In this cadaveric model, arthroscopically determined Geissler grade was associated with specific anatomic lesions of the scapholunate supporting ligaments. Sequential sectioning of the ligaments showed a progressive increase in Geissler grade. CLINICAL RELEVANCE Knowledge of the association of Geissler grade with pathoanatomy may aid the surgeon in deciding which reconstructive method is best.

Abstract
Distal radioulnar joint (DRUJ) arthritis presents a challenging problem. Surgical interventions include resection arthroplasties, such as the Darrach procedure and hemiresection arthroplasty, the Sauve-Kapandji procedure, and more recently prosthetic replacement for either the ulnar head or the entire DRUJ. Resection arthroplasties have been associated with complications, including instability and radioulnar convergence. The prosthetic replacements have been designed in an attempt to restore more normal DRUJ kinematics. This paper provides a review of the anatomy and biomechanics of the DRUJ and discusses the outcomes of the available surgical options for symptomatic DRUJ arthritis. The arthritic distal radioulnar joint (DRUJ) is a difficult problem. Many of the surgical interventions developed for this condition are associated with complications,such as instability and radioulnar convergence. Recently, prosthetic replacement of either the ulnar head or the entire DRUJ has been advocated in order to better restore the kinematics of the joint. A review of the anatomy and biomechanics of the DRUJ and a discussion of the numerous surgical options and their outcomes is provided.

Abstract
PURPOSE To describe the features of displaced intra-articular fractures confined to the volar rim of the distal radius and compare outcomes after their operative fixation to complete intra-articular and extra-articular fractures treated with operative fixation. METHODS A total of 627 distal radius fractures were treated over a 6-year period. Twenty-eight patients had volar rim fractures (type 23-B3, as classified by the Orthopaedic Trauma Association [OTA]), all treated with operative reduction and fixation using a volar buttress plate. Clinical outcome information including radiographs, Short Form-36 health survey, and Disabilities of the Arm, Shoulder, and Hand questionnaire were collected at regular postoperative intervals. Patients with volar rim fractures were compared with patients who sustained other types of operatively managed distal radius fractures (OTA types 23-A, 23-B1/B2, and 23-C). RESULTS The most common type of volar rim fracture consisted of a single large fragment (OTA 23-B3.2; 46%), followed by comminuted fractures (OTA 23-B3.3; 36%). Restoration of radiographic parameters was similar between groups except for an increased volar tilt in volar rim fractures compared with group 23-B1/B2. Active wrist and finger motion improved in all groups except for wrist extension, which was less in the 23-B1/B2 groups. The 23-B1/B2 group had the greatest pain and worst Short Form-36 scores. Disabilities of the Arm, Shoulder, and Hand questionnaire scores were similar and without differences between groups. CONCLUSIONS Our data suggest that patients with volar rim distal radius fractures can expect a rapid return to function with minimal risk for complications and have outcomes similar to other types of operatively treated distal radius fractures. Further investigation of type 23-B fractures (23-B1/B2) is warranted owing to evidence of diminished outcomes.

Abstract
PURPOSE In order to identify predictors for hand stiffness following distal radius fractures and understand the consequences of this common clinical finding, we studied 260 patients. Our null hypothesis was that we would find no predictors of post injury hand stiffness. METHODS Baseline demographics and injury characteristics were obtained at distal radius fracture presentation. Treatment and healing was documented. Stiffness was defined as tip to palm distance greater than 1 cm for any one finger. Outcome parameters obtained at regular intervals included wrist and hand range of motion, radiographs, visual analog pain scales, and Disability of the Arm Shoulder and Hand (DASH) questionnaires. RESULTS Forty-nine of 260 patients (19%) patients were considered to be "stiff" by our criteria. Grip strength was weaker for stiff patients as well. Patient demographics were similar in both groups with the "stiff" cohort having a greater mean age, p = 0.05. There was no significant difference in stiffness seen in operative cases versus nonoperative cases. Injury ulnar variance was 3.1mm (SD = 3.5) in the "stiff" cohort and 1.8 (SD = 2.9) in the "non-stiff" cohort (p= 0.02). Functional disability as measured by the DASH differed (p = 0.001) between stiff and non-stiff patients for both 6 month and 1 year follow-up time points. Stiff patients were more likely than non-stiff patients to have lower grip strength at 12-month post fracture (p = 0.001). CONCLUSION Older patients who present with significant ulnar variance at injury are more likely to experience hand stiffness at some time during their recovery. The development of hand stiffness is associated with poorer functional outcome than those who do not develop stiffness.

Abstract
PURPOSE To report radiographic, clinical, and patient-based functional outcomes following contemporary operative treatment of patients who sustained an open distal radius fracture and compare them to a similar group of patients treated operatively for closed distal radius fractures. METHODS Over five years, 601 patients with a distal radius fracture presented to our academic medical center, including one Level 1 trauma hospital, and were prospectively enrolled in an upper extremity trauma database. Patients with open distal radius fractures underwent irrigation, debridement, and operative fixation within 24 hours of presentation. Closed distal radius fractures requiring operative fixation were treated electively. Retrospective review of the database identified eighteen open fractures of the distal radius (11 type I, 6 type II, 1 type IIIa). The open fracture patients were individually matched with eighteen closed distal radius fracture patients who underwent surgical fixation based on age, sex, injury to dominant extremity, fracture pattern, and method of fracture fixation. Clinical, radiographic, patient- based functional outcomes, and complications were recorded at routine postoperative intervals. RESULTS Follow-up was greater than 77% in both groups at all time points. The open and closed groups were similar in regards to age, gender, BMI, race, tobacco use, income, employment status, hand dominance, injury to dominant extremity, mechanism of injury, fracture classification, method of fracture fixation, and presence of concomitant injury. Postoperative complications and reoperation rates were similar between the open and closed groups. Union rates and radiographic alignment one year postoperatively were similar between the open and closed fracture groups. At final follow-up, range of motion parameters, grip strengths, DASH indices, and subjective pain scores were similar between both groups. DISCUSSION Open distal radius fractures treated with early debridement and fixation achieved similar outcomes to surgically treated closed fractures of the distal radius when followed for a year or more postoperatively.

Abstract
Polydactyly of the hand is a difficult problem and poses a unique challenge for the hand surgeon. The embryology of limb development is complex, leading to a host of different phenotypes of polydactyly. Polydactyly can occur in any digit and is described as preaxial, postaxial, and central, based on location. Classification systems exist for each of these locations, which guide treatment options. Surgical treatment needs to address the aesthetic and functional aspect of hand reconstruction. Careful consideration and planning of surgical treatment individualized to each patient is required to obtain the best possible outcome.

Abstract
Extra-articular middle phalangeal neck fractures are uncommon fractures of the hand that are often difficult to treat. Surgery is indicated when closed reduction fails; 1 option is closed reduction and percutaneous pinning. Maintaining closed reduction while inserting K-wires is challenging. We present a new technique for percutaneous pinning of these fractures that was developed to address these issues. Our technique uses flexion of the interphalangeal joints during K-wire insertion to maintain fracture reduction and improve fixation.

Abstract
Contractures of the intrinsic muscles of the fingers disrupt the delicate and complex balance of intrinsic and extrinsic muscles, which allows the hand to be so versatile and functional. The loss of muscle function primarily affects the interphalangeal joints but also may affect etacarpophalangeal joints. The resulting clinical picture is often termed, intrinsic contracture or intrinsic-plus hand. Disruption of the balance between intrinsic and extrinsic muscles has many causes and may be secondary to changes within the intrinsic musculature or the tendon unit. This article reviews diagnosis, etiology, and treatment algorithms in the management of intrinsic contractures of the fingers.

Abstract
A 29-year-old female presented with pain and a palpable mass in the left wrist. Imaging demonstrated a multiloculated cystic mass adjacent to the radial aspect of the scaphoid, which was intimately associated with and appeared to arise from the wall of the radial artery and its dorsal branch. The mass was surgically resected. The histological analysis confirmed the presence of adventitial cystic disease (ACD) of the radial artery. In addition, within a year time span, a second 34-year-old male patient presented with a palpable mass in the right hand. Imaging demonstrated a cystic mass encasing the dorsal carpal branch of the radial artery and its terminal vessels to the thumb and index finger. The diagnosis of ACD was raised based on MR imaging. Histological analysis confirmed the presence of an adventitial cyst. ACD of the arteries is a rare disorder of unknown etiology, which usually involves the popliteal artery. Less common sites of involvement include the external iliac, common femoral, radial, and ulnar arteries. To our knowledge, there have only been six previous case reports of adventitial cystic disease involving the radial artery. The imaging features, histology, differential diagnosis, pathogenesis, and treatment are discussed.

Abstract
Group A streptococcus is responsible for a diverse range of soft tissue infections. Manifestations range from minor oropharyngeal and cellulitic skin infections to more severe conditions such as necrotizing fasciitis and septic shock. Troubling increases in the incidence and the severity of streptococcal infections have been reported over the past 25 years. Cases of streptococcal necrotizing fasciitis have received significant attention in the literature, with prompt surgical debridement being the mainstay of treatment. However, cases of rapidly progressing upper extremity streptococcal cellulitis leading to shock and a subsequent surgical intervention have not been well described. This article presents a case of an 85-year-old woman with a rapidly progressing, erythematous, painful, swollen hand associated with fever, hypotension, and mental status change. Due to a high clinical suspicion for necrotizing fasciitis, the patient was rapidly resuscitated and underwent immediate surgical irrigation and debridement. All intraoperative fascial pathology specimens were negative for necrotizing fasciitis, leading to a final diagnosis of Group A streptococcal cellulitis. Although surgical intervention is not commonly considered in patients with cellulitis, our patient benefited from irrigation and debridement with soft tissue decompression. In cases of necrotizing fasciitis as well as rapidly progressive cellulitis, prompt diagnosis and aggressive treatment may help patients avoid the catastrophic consequences of rapidly progressive group A streptococcal infections.

Abstract
BACKGROUND There is much debate regarding the optimal treatment of displaced, unstable distal radial fractures in the elderly. The purpose of this retrospective review was to compare outcomes for elderly patients with a displaced distal radial fracture who were treated with or without surgical intervention. METHODS This case-control study examined ninety patients over the age of sixty-five who were treated with or without surgery for a displaced distal radial fracture. All fractures were initially treated with closed reduction and splinting. Patients who failed an acceptable closed reduction were offered surgical intervention. Patients who did not undergo surgery were treated until healing with cast immobilization. Patients who underwent surgery were treated with either plate-and-screw fixation or external fixation. Baseline radiographs and functional scores were obtained prior to treatment. Follow-up was conducted at two, six, twelve, twenty-four, and fifty-two weeks. Clinical and radiographic follow-up was completed at each visit, while functional scores were obtained at the twelve, twenty-four, and fifty-two-week follow-up evaluations. Outcomes at fixed time points were compared between groups with standard statistical methods. RESULTS Forty-six patients with a mean age of seventy-six years were treated nonoperatively, and forty-four patients with a mean age of seventy-three years were treated operatively. Other than age, there was no difference with respect to baseline demographics between the cohorts. At twenty-four weeks, patients who underwent surgery had better wrist extension (p = 0.04) than those who had not had surgery. At one year, this difference was not seen. No difference in functional status based on the Disabilities of the Arm, Shoulder and Hand scores and pain scores at any of the follow-up points was seen between the groups. Grip strength at one year was significantly better in the operative group. Radiographic outcome was superior for the patients in the operative group at each follow-up interval. There was no difference between the groups with regard to complications. CONCLUSIONS Our findings suggest that minor limitations in the range of wrist motion and diminished grip strength, as seen with nonoperative care, do not seem to limit functional recovery at one year.

Abstract
The distal radioulnar joint (DRUJ) acts in concert with the proximal radioulnar joint to control forearm rotation. The DRUJ is stabilized by the triangular fibrocartilage complex (TFCC). This complex of fibrocartilage and ligaments support the joint through its arc of rotation, as well as provide a smooth surface for the ulnar side of the carpus. TFCC and DRUJ injuries are part of the common pattern of injuries we see with distal radius fractures. While much attention has been paid to the treatment of the distal radius fractures, many of the poor outcomes are due to untreated or unrecognized injuries to the DRUJ and its components.

Abstract
We performed a prospective, randomised trial to evaluate the outcome after surgery of displaced, unstable fractures of the distal radius. A total of 280 consecutive patients were enrolled in a prospective database and 88 identified who met the inclusion criteria for surgery. They were randomised to receive either bridging external fixation with supplementary Kirschner-wire fixation or volar-locked plating with screws. Both groups were similar in terms of age, gender, hand dominance, fracture pattern, socio-economic status and medical co-morbidities. Although the patients treated by volar plating had a statistically significant early improvement in the range of movement of the wrist, this advantage diminished with time and in absolute terms the difference in range of movement was clinically unimportant. Radiologically, there were no clinically significant differences in the reductions, although more patients with AO/OTA (Orthopaedic Trauma Association) type C fractures were allocated to the external fixation group. The function at one year was similar in the two groups. No clear advantage could be demonstrated with either treatment but fewer re-operations were required in the external fixation group.

Abstract
PURPOSE To prospectively compare the efficacy of 2-octylcyanoacrylate (Dermabond; Ethicon Inc, Somerville, NJ) with standard suture repair in the management of nail bed lacerations. METHODS Forty consecutive patients with acute nail bed lacerations were enrolled in this study. Eighteen patients were randomized to nail bed repair using Dermabond (2-octylcyanoacrylate), and 22 were randomized to standard repair using 6-0 chromic suture. At presentation, demographic information and laceration characteristics were recorded. The time required for nail bed laceration repair with each method was documented, and cosmetic and functional outcomes were assessed at 1, 3, and 6 months after injury. Comparisons between treatment groups were made using unpaired Student's t-tests. RESULTS The Dermabond repair group was composed of 10 males and 8 females with a mean age of 32.3 years. The suture repair group was composed of 17 males and 5 females with a mean age of 29.5 years. The mean follow-up was 5.1 months (range 4-11 months) and 4.8 months (range 4-11 months) for the Dermabond group and suture group, respectively. There was no difference between the two treatment groups with respect to age, comorbidities, and length of follow-up (p>.05). The average time required for nail bed repair using Dermabond was 9.5 minutes, which was significantly less than that required for suture repair (27.8 minutes) (p<.0003). At each follow-up time point, there was no statistical difference in physician-judged cosmesis, patient-perceived cosmetic outcome, pain, or functional ability between the Dermabond and suture treatment cohorts (p>.05). CONCLUSIONS Nail bed repair performed using Dermabond is significantly faster than suture repair, and it provides similar cosmetic and functional results. In the management of acute nail bed lacerations, Dermabond is an efficient and effective repair technique. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic I.

Abstract
The role of medical, social, and functional covariates on mortality after hip fracture was examined over a 16-year period. A total of 1109 patients with hip fractures were included in a prospective database. The inclusion criteria were patients who were age 65 years or older, ambulatory prior to fracture, cognitively intact, living in their own home at the time of the fracture, and had sustained a nonpathological femoral neck or intertrochanteric chip fracture. Data were analyzed using a Cox proportional hazards model. Mortality was compared with a standardized population, and standardized mortality ratios were calculated for 1, 2, 3, 5, and 10 years,respectively. The 1-, 2-, 5- and 10-year mortality rates were 11.9%, 18.5%, 41.2%, and 75.3%, respectively. The predictors of mortality were advanced age, male gender, high American Society of Anesthesiologists (ASA)classification, the presence of a major postoperative complication, a history of cancer, chronic obstructive pulmonary disorder, a history of congestive heart failure,ambulating with an assistive device, or being a household ambulator prior to hip fracture. The increased mortality risk was highest during the first year after hip fracture and returned to the risk of the standard population 3 years postoperatively. Males who are 65 to 84 years had the highest mortality risk.

Abstract
Clavicle fractures are common skeletal injuries that are typically managed nonoperatively, which results in a high rate of fracture union with few or no long-term sequelae. Type II distal clavicle fractures are an exception, with reported rates of nonunion ranging from 22% to 44%. This high rate of nonunion has led to controversy regarding the appropriate treatment of type II injuries. The following case report describes a type IIB distal clavicle fracture, in which nonoperative management was complicated by the breakdown of skin over the fracture site and the subsequent development of infection. This is a rare complication of conservative management. Thorough operative debridement, fracture stabilization via external fixation, and identification of the causative organism allowed for successful outcome in the management of this complex presentation.

Abstract
Child abuse continues to be a serious problem that is likely to be encountered in all medical specialties, with orthopaedic surgeons commonly evaluating children having sustained musculoskeletal injuries. In busy emergency departments and clinics, junior residents shoulder much of the responsibility in identifying cases of abuse. We report the case of an otherwise healthy 18-month-old child, who presented to the emergency room with bilateral humeral shaft and corner fractures. These injuries were originally presented to the orthopaedic resident as having occurred from an accidental fall from a crib. The appropriate evaluation for a patient suspected of sustaining an injury from child abuse is reviewed.

Abstract
Isolated fractures of the trapezoid bone have been rarely reported in the literature, the mechanism of injury being an axial or bending load transmitted through the second metacarpal. We report a case of an isolated, nondisplaced trapezoid fracture that was sustained by direct trauma and subsequently treated successfully in a short-arm cast. Diagnostic and treatment strategies for isolated fractures of the trapezoid bone are reviewed as well as the results of operative and nonoperative treatment.

Abstract
Complete anaesthesia in the cutaneous distribution of the ulnar nerve following submuscular anterior transposition of the ulnar nerve has not been previously reported. We postulate vascular insult as the etiology of this condition and suggest there may be clinical importance to preserving the ulnar nerve blood supply during submuscular anterior transposition.

Abstract
BACKGROUND Several previous studies have described reconstructive methods for the treatment of an injury to the ulnar collateral ligament of the thumb. However, there are few biomechanical studies to date to analyze the strength of the surgical reconstruction. PURPOSE To evaluate 2 reconstruction techniques with use of a cadaveric model: (1) reconstruction with the use of a free tendon graft placed in a figure-of-8 fashion through drill holes in the metacarpal and proximal phalanx of the thumb, and (2) reconstruction with the use of the Bio-Tenodesis Screw System. STUDY DESIGN Controlled laboratory study. METHODS Eight matched pairs of cadaveric specimens underwent removal of the proper and accessory ulnar collateral ligaments. One of the 2 reconstruction methods was performed, and specimens were mounted on a materials-testing machine. The specimens were subjected to valgus stress to failure at 30 degrees of flexion. Failure was defined as valgus laxity of 30 degrees at the metacarpophalangeal joint. RESULTS The peak load to failure was 23.5 +/- 11.4 N for the figure-of-8 reconstruction and 24.3 +/- 12.3 N for the reconstruction using the Bio-Tenodesis Screw System. Comparing the 2 groups, there was no statistically significant difference in peak loads to failure (P = .88). CONCLUSION There was no statistically significant difference between the peak loads to failure of the 2 reconstructions. CLINICAL RELEVANCE The Bio-Tenodesis Screw System may provide another viable option for surgical reconstruction of the ulnar collateral ligament of the thumb.

Abstract
Fracture-dislocation of the elbow is a signiicant injury with mixed outcomes. The purpose of the study was to evaluate patient perceived outcome following surgical stabilization of these complex injuries. Twenty-nine available patients (76%) from 37 identiied with "terrible triad" injury patterns, in- cluding ulnohumeral dislocation, radial head fracture, and coronoid fracture, were available for a minimum 1-year follow-up (mean, 27 months). All patients were evaluated by their treating physician. Radiographic outcome was evaluated at latest follow-up. Functional outcome was based upon DASH, Mayo elbow performance, and Broberg-Mor- rey scores. Complications were recorded. Results included that the average lexion-extension arc of elbow motion was 109 degrees +/- 27 degrees , and the average pronation-supination arc was 128 degrees +/- 44 degrees . Grip strength averaged 72% of the contralateral extremity. The Mayo score was a mean of 81 (range, 45 to 100), the Broberg-Morrey mean was 77 (range, 33 to 100) The mean DASH was 28 (range, 0 to 72). When compared to the age-based normal values, the mean patient's DASH score was 1.4 SD worse than an average person of the same age None of the injury characteristics, patient demographics or treatment modalities was signiicantly associated with a poor outcome at the 95% conidence interval. Conclusions are that the results with terrible triad injuries are often unsatisfactory, but surgical management with the use of a systematic approach may be beneicial. Our approach led to the restoration of elbow joint stability in all patients.

Abstract
The purpose of this study was to analyze the relative bio- mechanical stability of three types of internal ixation with cancellous bone graft in a cadaveric, scaphoid nonunion model. A scaphoid nonunion model was created by remov- ing a volar wedge of bone from the waist of the scaphoid in 18 fresh frozen human cadavers. Cancellous sawbone graft was inserted into the osteotomy site and three groups of six cadavers each were then internally ixed with a pair of parallel 0.045-inch K-wires, Mini-Acutrak screws, or Standard Acutrak screws, respectively for each group. The potted specimens were tested using an Instron(R) tensile testing machine by applying force to the distal pole of the scaphoid. The load and stiffness were calculated at 2 mm and 4 mm of displacement. Results showed that both the Mini-Acutrak screw and the Standard Acutrak screw were statistically stronger and stiffer at 2 mm displacement than the pair of parallel 0.045-inch K-wires. No statistically sig- niicant difference between the Standard and Mini-Acutrak screws was noted at 2 mm displacement. At higher loads (4 mm displacement), the Standard Acutrak became statisti- cally stronger and stiffer than the Mini-Acutrak screw. It was concluded that the Standard Acutrak screw followed by the Mini-Acutrak screw may be a better option than a pair of parallel 0.045-inch K-wires when treating scaphoid nonunions. The screws have increased strength of ixation and stiffness when compared to K-wires. Also, unlike the K wires, the Acutrak screws enhance fracture healing by achieving interfragmentary compression. Even in a cancel- lous bone graft model, interfragmentary compression was achieved and our concern that the bone graft would "spit out" was allayed.

Abstract
Etiologies of elbow contractures can be classified into intrinsic versus extrinsic causes. Posttraumatic elbow stiffness is the most common intrinsic cause and HO formation is the most common extrinsic cause of elbow contractures. Patients who sustain significant elbow trauma and have one or more risk factors for HO formation should be given prophylaxis against HO formation in the form of either indomethacin or radiation therapy. Early excision of HO has been shown to be safe and effective. Nonoperative measures are most effective if used within 6 months of contracture onset. These measures include physical therapy and an aggressive splinting program. If nonoperative measures are unsuccessful and the patient has functionally limiting elbow ROM, then surgical intervention should be considered. Careful preoperative assessment of the ulnar nerve is mandatory, as it may need to be transposed. Satisfactory results have been reported with arthroscopic elbow contracture releases. However, this procedure is technically challenging, with the potential for serious neurovascular complications. Satisfactory results have been published for open procedures as well. The direction of the greatest limitation of motion, the presence of ulnar nerve dysfunction, and the location of osteophytes all help to dictate which surgical approach should be selected.
