Comparison of Low-Dose Computed Tomography Versus Conventional-Dose Computed Tomography in the Evaluation of Distal Radius Fractures.

BACKGROUND: Distal radius fractures (DRFs) are common upper extremity fractures and often require surgical fixation when they are intraarticular. Preoperative computed tomography (CT) has emerged as a surgical planning tool to evaluate intraarticular DRFs. Although CT affords additional details, patients receive higher radiation doses than standard radiographs. We aim to develop a low-dose CT (LDCT) protocol, relative to the institutional standard-dose CT wrist for intraarticular DRFs although providing adequate detail for surgical decision-making. METHODS: A single-institution prospective study was conducted on patients with intraarticular DRFs who underwent closed reduction and below-elbow splinting who otherwise would undergo wrist CT. Observations were defined as total measurements taken, with each view undergoing 44 measurements. Patients underwent 2 scans with a standard dose and a 10× dose reduction. Articular step and gap measurements were recorded in the sagittal and coronal images. RESULTS: A total of 11 patients were enrolled (7 women and 4 men). The mean age was 55 years (SD = 20.1). There were a total of 4 reviewers: 1 attending surgeon, 2 resident physicians, and 1 student. When comparing LDCT and conventional-dose CT (CDCT), there were no significant differences in step and gap measurements across all reviewers. CONCLUSION: This study demonstrated that LDCT provides comparable imaging quality for surgical planning as a CDCT without significant diagnostic decay in the setting of DRFs. This comes with the added benefit of a 10-fold reduction in radiation exposure. These results suggest that LDCT is an opportunity to reduce effective radiation in patients although providing beneficial preoperative imaging.

Comparison Between Intramedullary Nail and Percutaneous Pin Fixation in Proximal Phalanx Fractures.

BACKGROUND: Percutaneous pinning has been the predominant technique for fixation of proximal phalanx fractures, but stiffness is a reported complication. The introduction of intramedullary (IM) nail fixation of proximal phalanx fractures provides a stronger biomechanical fixation for amenable fracture patterns with the added benefit of not tethering the soft tissue. The goal of this study was to compare the surgical outcomes of IM nail and percutaneous pin fixation in isolated proximal phalanx fractures. METHODS: A retrospective review was performed at our institution between the years 2018 and 2022 for patients treated for proximal phalanx fractures. Patients that underwent fixation with IM nails or percutaneous fixation for isolated extraarticular proximal phalanx fractures were included. Patients were excluded if they had concomitant hand fractures, tendon injury, or intraarticular extension. RESULTS: A total of 50 patients were included in this study. Twenty-eight patients received percutaneous pin fixation, and 22 patients underwent IM nail or screw fixation. There was no significant difference in injury patterns or demographics between these two groups. Patients that underwent IM nail fixation had a significantly quicker return to active motion, shorter duration of orthosis treatment, and fewer occupational therapy visits. In addition, patients in the IM fixation group had significantly improved range of motion (ROM) at 6 weeks postoperatively. CONCLUSIONS: This study demonstrates that patients receiving percutaneous pin or IM nail fixation have equivocal union and complication rates. The IM nail fixation group was able to have quicker return to mobilization, fewer required occupational therapy visits, and improved early ROM.

Relative Increase in Distal Radius Exposure with Extension of the FCR Approach.

Objectives: Major surgical approaches for volar plating of the distal radius include the standard flexor carpi radialis (FCR) approach, the extended FCR (eFCR) approach, and the extended FCR approach combined with radial-sided carpal tunnel release (eFCR+CTR). The purpose of this study was to determine which of these three surgical approaches offers the greatest exposure and visualization of the distal radius. Methods: Sequential dissections were performed on each of 30 fresh frozen below elbow cadaveric samples in order to simulate the three surgical approaches for distal radius volar plating, starting with the standard FCR approach, advancing to eFCR, and finishing with eFCR+CTR. Prior to the initial dissection of each cadaveric sample, radiographs were taken in order to calculate the total area of the distal radius. Then, following each sequential dissection, photographs were taken of each specimen and analyzed with an image measuring software in order to obtain the area of distal radius exposed. The percentage of total distal radius exposure was then calculated for each of the three surgical approaches. Results: The eFCR+CTR approach offered the greatest average distal radius exposure at 87% of total distal radius visualized. The eFCR approach provided the next greatest exposure with an average of 73% visualized, followed by the standard FCR approach with an average of 61% visualized. Conclusion: The extended FCR approach with radial-sided carpal tunnel release is both safe and efficacious for osteosynthesis of distal radius fractures in the setting of concomitant carpal tunnel syndrome. This study demonstrates that an additional advantage of this approach includes improved surgical exposure and visualization of the distal radius. This surgical approach is a valuable addition to any upper extremity surgeon's armamentarium and should be considered when treating difficult distal radius fractures.

Advances in Soft Tissue Injuries Associated with Open Fractures.

Management of soft tissue injury is a key component in the overall treatment of upper extremity fractures. Hand surgeons must rely on their armamentarium for treating soft tissue deficits for functional outcomes. Understanding the role of fracture fixation and wound adjuncts, including negative pressure wound therapy and dermal regenerative templates, is the keys to success. In addition, detailed knowledge of local and free tissue options is essential for hand reconstruction.

Underrepresentation of African Americans in Plastic Surgery: Examining Demographics, Specialty Factors, and Medical School Experiences.

BACKGROUND: Racial representation among medical trainees translates into physicians that are able to communicate with diverse patient populations and are perceptive to health disparities. This is important within plastic surgery where an optimal physicianpatient relationship is essential to health outcomes. OBJECTIVE: The purpose of this study is to address underrepresentation of African Americans (AA) in plastic surgery through improving understanding of factors that may contribute to AA medical student interest in plastic surgery. DESIGN: This was a voluntary, cross-sectional survey. An online survey was designed to collect information on demographics, specialty factor importance, medical school experiences, and plastic surgery interest among medical students. The survey was distributed to medical students within three national medical organizations between August 2018 and February 2019. The following groups of respondents were statistically COMPARED: AAs interested vs. AAs not interested in plastic surgery and AA vs. Caucasian medical students both interested in plastic surgery. SETTING: Online survey for medical students in the United States. PARTICIPANTS: All 428 participants were medical students that belonged to at least 1 of the 3 national medical organizations between August 2018 and February 2019. RESULTS: The survey was completed by 428 participants of which 142 were excluded for incomplete surveys, leaving 286 (66.8%) participants to be included in the study. Among AA medical students, 128 (75.3%) were not interested in Plastic Surgery and 42 (24.7%) were interested. The 2 groups were similar demographically but differed significantly across multiple specialty factors and medical school experiences (p < 0.05). When compared to interested Caucasian medical students (n = 30), interested AA medical students differed significantly in demographics, specialty factors, and medical school experiences (p < 0.05). CONCLUSIONS: This study supports the implementation of medical school interventions emphasizing specialty factors and medical school experiences unique to AA medical students interested in plastic surgery to promote their application into the specialty.

Management of Complex Hand and Wrist Ligament Injuries.

Ligamentous injuries in the hand and wrist are often underdiagnosed and can present with significant functional limitations if there is untimely recognition of injury. Adequate repair or reconstruction is critical in restoring joint stability and mobility. The purpose of this review is to provide an overview of the metacarpophalangeal joint, scapholunate interosseous ligament (SLIL), and non-SLIL carpal ligament anatomy, diagnosis, imaging, treatment consideration and options, as well as surgical techniques encompassing repair, reconstruction, and fusion.

Recalcitrant Neuropathies in the Upper Extremity.

Carpal and cubital tunnel syndrome can cause debilitating pain and weakness in the hand and upper extremities. Although most patients have a resolution of their symptoms after primary decompression, managing those with recalcitrant neuropathies is challenging. The etiology of persistent, recurrent, or new symptoms is not always clear and requires careful attention to the history and physical examination to confirm the diagnosis or consider other causes prior to committing to surgery. Nevertheless, revision surgery is often needed in the setting of recalcitrant neuropathies in order to improve patients' symptoms. Revision surgery typically entails wide exposure and neurolysis to release residual compression. In addition, vascularized tissue and nerve wraps have been routinely used to create a favorable perineural environment that decreases recurrent scar formation. This review discusses the etiologies of recalcitrant upper extremity neuropathies, the current treatment options, and surgical outcomes.

Two Thumbs Down: A 10-Year Analysis of Crossbow-Related Hand and Digit Injuries in the United States.

BACKGROUND: Modern crossbow is a popular weapon used throughout the United States for outdoor recreation. Crossbow mechanics place the hand and digits at significant risk of injury while shooting or handling these weapons; however, injury patterns have been poorly documented. In this study, the authors use a national database to assess patterns of crossbow-related injuries of the hand and digits. METHODS: A retrospective review of the National Electronic Injury Surveillance System database was conducted to identify crossbow-related hand and digit injuries over the past 10 years. Demographic data, injury timing, anatomical injury location, specific injury diagnosis, and disposition data were collected. RESULTS: A total of 15 460 crossbow-related hand injuries were identified between 2011 and 2021. A strong temporal relationship was identified, with 89% of injuries occurring between the months of August and December. Male patients sustained most injuries (>85%). Body areas injured were the digits (93.2%) and the hand (5.7%). The most common injuries were laceration (n = 7520, 48.6%), fracture (n = 4442, 28.7%), amputation (n = 1341, 8.7%), and contusion/abrasion (n = 957, 6.2%). More than 50% of cases involved injury to the thumb, with approximately 750 thumb amputations recorded during the time period examined. CONCLUSIONS: This study is the first to document the patterns of hand and digit injuries associated with crossbow use on a national scale. These findings have important implications for public health awareness campaigns targeting hunters and support the designation of crossbow "safety wings" as a mandatory feature of crossbow design.

Recent Smoking History Is Not Associated with Adverse 30-Day Standardized Postoperative Outcomes following Microsurgical Reconstructive Procedures of the Upper Extremity.

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

Contexte: La reconstruction microchirurgicale du membre supérieur repose sur la bonne guérison de la plaie pour des résultats optimaux. Le tabagisme est associé à des complications pour la guérison des plaies; toutefois, les conclusions concernant ses répercussions sur les résultats microchirurgicaux (réimplantation, revascularisation et transfert de tissu libre) sont variables. Nous avons cherché à savoir quelles étaient les répercussions du tabagisme sur les résultats postopératoires standardisés à 30 jours après reconstruction microchirurgicale du membre supérieur. Méthodes: Utilisant le Programme national d'amélioration de la qualité de la chirurgie, tous les patients ayant subi (1) un transfert de lambeau libre du membre supérieur (n = 70) et (2) une réimplantation/revascularisation (n = 270) ont été identifiés. Pour chaque procédure, les patients ont été classés en fonction de leurs antécédents de tabagisme récent (fumeur actuel ≤ 1 an préopératoire). Les données démographiques initiales et les complications standardisées à 30 jours, les réinterventions et les réhospitalisations ont été comparées entre fumeurs et non-fumeurs. Résultats: Concernant les réimplantations/revascularisations, il n'y a pas eu de différences en termes de sexe, race ou IMC entre les fumeurs (n = 77) et les non-fumeurs. Les fumeurs avaient une plus grande prévalence d'insuffisance cardiaque congestive (5,2 % contre 1,0 %, P = 0,036) et les non-fumeurs étaient plus souvent sous hémodialyse (15,6 % contre 10,4 %, P = 0,030). Concernant les patients ayant eu un transfert de lambeau libre, il n'y a pas eu de différences en termes d'âge, de sexe ou de race entre les fumeurs (n = 14) et les non-fumeurs. La durée d'hospitalisation des fumeurs a été plus longue (6,6 jours contre 4,2 jours, P =0,001) avec une prévalence plus élevée de MPOC (7,1 % contre 0 %, P = 0,044). Le tabagisme récent n'a pas été associé à une augmentation de la probabilité de complications chirurgicales standardisées, majeures ou mineures, à 30 jours, de réhospitalisation ou reprises chirurgicales après reconstruction microchirurgicale du membre supérieur par transfert de lambeau libre ou réimplantation/revascularisation. Le diagnostic de MPOC à l'inclusion dans l'étude n'était pas non plus un facteur prédictif d'événements indésirables à 30 Jours après transfert de lambeau libre. Conclusion: Un antécédent de tabagisme récent n'a pas été associé à des résultats indésirables à 30 jours après reconstruction microchirurgicale du membre supérieur via réimplantation/revascularisation ou transfert de lambeau libre. À la lumière de ces constatations, des études supplémentaires portant particulièrement sur les événements indésirables propres aux procédures de lambeaux libres et de réimplantation/revascularisation sont justifiées.

Dermal Regenerative Templates in Orthopaedic Surgery.

Management of soft-tissue injuries is a critical principle in the treatment of orthopaedic trauma. Understanding the options for soft-tissue reconstruction is vital for successful patient outcomes. Application of dermal regenerative templates (DRTs) in traumatic wounds has created a new rung in the reconstructive ladder bridging the gap between skin graft and flap coverage. There are multiple DRT products with specific clinical indications and mechanisms of action. This review outlines the up-to-date specifications and uses of DRT in commonly seen orthopaedic injuries.

Variations in Incidence of Trigger Finger and Response to Corticosteroid Injection after Aromatase Inhibitor Therapy for Breast Cancer.

BACKGROUND: Aromatase inhibitors (AIs), such as letrozole and anastrozole, have been demonstrated to have significant musculoskeletal symptoms in patients. The purpose of this study was to evaluate the effect of specific AI medications on the incidence of trigger finger and independent factors affecting treatment outcomes within this population. METHODS: A retrospective chart review was performed at the authors' institution between the years 2014 and 2018 in patients with the diagnosis of breast cancer. This cohort was then sorted based on receiving medication regimens, trigger finger diagnosis, steroid injections, and need for surgical release of trigger finger. RESULTS: A total of 15,144 patients were included for initial review. The overall rate of trigger finger diagnosis was 2.75% in the entire breast cancer population and 4.5% for patients receiving AI therapy. Patients taking letrozole and anastrozole had an increased odds ratio of 2.0 and 1.7, respectively, for developing trigger finger. Patients who switched between letrozole and anastrozole during treatment had a higher rate of failed steroid injection treatment (45.2% versus 23.5%; P = 0.021). Among patients receiving AI treatment diagnosed with trigger finger, diabetes and hemoglobin A1c level greater than 6.5 were associated with significantly increased rates of failed steroid therapy. CONCLUSIONS: Patients receiving AI therapy have an increased incidence of trigger finger. The outcomes of treatment are equivalent between AI and non-AI trigger finger populations. However, steroid therapy is more likely to fail in patients who require switching of regimens because of significant musculoskeletal symptoms. Poorly controlled diabetes was also an independent factor for compromised steroid treatment of trigger finger. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Arthroscopic TFCC Ulnar Bone Tunnel Foveal Repair in Adult Patients.

Triangular fibrocartilage complex (TFCC) tears may cause persistent ulnar-sided wrist pain, loss of grip strength, and associated loss of function. Although the majority of TFCC tears can be treated nonoperatively, surgical repair is considered when conservative measures fail. TFCC tears with foveal disruption and instability of the distal radioulnar joint (DRUJ) require direct repair of the TFCC to the ulnar fovea. The traditional method of foveal TFCC repair involves an open surgical approach through the floor of the 5th dorsal compartment. However, this open approach causes disruption of structures such as the dorsal ulnocarpal capsule, the extensor retinaculum, and, potentially, the distal radioulnar ligament (DRUL). This article describes, in detail, the recently developed arthroscopic assisted ulnar foveal bone tunnel repair. This method spares dorsal structures that may be disrupted during an open surgical approach and creates a robust repair of the TFCC deep fibers with restoration of DRUJ stability.

Upper Extremity Free Flap Transfers: An Analysis of the National Surgical Quality Improvement Program Database.

Introduction We evaluated the demographics, flap types, and 30-day complication, readmission, and reoperation rates for upper extremity free flap transfers within the National Surgical Quality Improvement Program (NSQIP) database. Materials and Methods Upper extremity free flap transfer patients in the NSQIP from 2008 to 2016 were identified. Complications, reoperations, and readmissions were queried. Chi-squared tests evaluated differences in sex, race, and insurance. The types of procedures performed, complication frequencies, reoperation rates, and readmission rates were analyzed. Results One-hundred-eleven patients were selected (mean: 36.8 years). Most common upper extremity free flaps were muscle/myocutaneous (45.9%) and other vascularized bone grafts with microanastomosis (27.9%). Thirty-day complications among all patients included superficial site infections (2.7%), intraoperative transfusions (7.2%), pneumonia (0.9%), and deep venous thrombosis (0.9%). Thirty-day reoperation and readmission rates were 4.5% and 3.6%, respectively. The mean time from discharge to readmission was 12.5 days. Conclusion Upper extremity free flap transfers could be performed with a low rate of 30-day complications, reoperations, and readmissions.

Primary Targeted Muscle Reinnervation after Below-Knee Amputation Is Not Associated with an Increased Risk of Major or Minor Surgical Complications: A Multi-Institutional, Propensity Score-Matched Analysis.

BACKGROUND: Targeted muscle reinnervation has emerged as a technique to reduce neuroma and phantom limb pain after below-knee amputation; however, the incidence of postoperative complications remains unknown. This multi-institutional study assessed the risk of postoperative complications among patients who underwent targeted muscle reinnervation at the time of below-knee amputation. METHODS: Patients who underwent below-knee amputation with targeted muscle reinnervation were propensity score-matched 1:3 to patients who underwent below-knee amputation alone. Study outcomes included the incidence of major or minor complications within 60 days. Regression models were used to estimate the relative risk of major and minor complications. RESULTS: Overall, 96 patients were matched, including 31 patients who had below-knee amputation with targeted muscle reinnervation and 65 who had below-knee amputation alone. In the matched sample, a higher incidence of major complications (29 percent versus 24.6 percent), readmission (25.8 percent versus 18.5 percent), and reoperation (19.4 percent versus 10.8 percent) was seen after both procedures compared with below-knee amputation alone. Patients who underwent both procedures displayed a higher incidence of minor complications (25.8 percent versus 20.0 percent), blood transfusion (22.6 percent versus 18.5 percent), and wound healing complications (45.2 percent versus 33.8 percent) and longer operative time (mean ± SD, 188.5 ± 63.6 minutes versus 88 ± 28.2 minutes). There was no statistically significant difference in the risk of major (relative risk, 1.20; 90 percent CI, 0.68, 2.11) or minor (relative risk, 1.21; 90 percent CI, 0.61, 2.41) complications between the two cohorts. CONCLUSIONS: Despite an increased incidence of postoperative complications, undergoing below-knee amputation with targeted muscle reinnervation does not confer a statistically significant increased risk of major or minor complications. Future studies are needed to delineate patient selection criteria when assessing the suitability of targeted muscle reinnervation at the time of major limb amputation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Symptom Duration and Diabetic Control Influence Success of Steroid Injection in Trigger Finger.

BACKGROUND: Trigger finger is one of the most common hand abnormalities, with a prevalence of 2 percent of the general population. Conservative treatment with corticosteroid injections at the A1 pulley has been shown to be a cost-effective first-line treatment. However, additional patient factors have not fully been described regarding steroid injection efficacy. The authors hypothesize that patients presenting with longer chronicity of symptoms before treatment and elevated blood glucose would have reduced success rates of steroid injection therapy. METHODS: A retrospective chart review of 297 patients at a single institution was performed between 2013 and 2019. Patients were included if they presented with the diagnosis of trigger finger and were treated with initial corticosteroid injection at the A1 pulley. RESULTS: Steroid injection therapy alone was successful in 65 percent of patients. Patients received on average of 1.61 steroid injections. Patients who failed treatment received an average of 1.85 injections compared to 1.49 for those who had successful corticosteroid injection therapy ( p = 0.001). Presence of ipsilateral hand disease was associated with significant increase in failure of steroid injections (43.4 percent versus 30.8 percent; p = 0.032). Diabetic patients with hemoglobin A1c levels greater than 6.5 percent had a significantly higher rate of failing steroid injection therapy (71.9 percent versus 38.1 percent; p < 0.001). Patients who presented with greater than 2.5 months of symptoms had a higher failure rate of corticosteroid therapy (40.4 percent versus 29.5 percent; p = 0.048). CONCLUSION: Patients with a coexisting diagnosis of diabetes and a hemoglobin A1c level greater than 6.5 percent, ipsilateral concomitant hand disease, or presence of symptoms for greater than 2.5 months should be counseled regarding higher risk of failure of local corticosteroid injection. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Outcomes associated with proton pump inhibitors and distal radius fractures: A post-hoc comparative analysis.

Long-term, high-dose, daily proton pump inhibitors (PPI) may impact outcomes associated with distal radius fractures (DRF). The hypothesis was that differences existed in patient demographics, but there existed no differences in injury patterns, interventions, post-operative complications, and patient-reported outcomes between patients not on a PPI and patients on a PPI with a DRF. METHODS: An IRB-approved, post-hoc analysis of patients with DRF from 2012 through 2018 was performed. Patients included were age ≥18 years, sustained a DRF, had completed medical and medication records, Quick Disabilities of the Arm, Shoulder and Hand (DASH) scores, Global Assessment of Functioning (GAF) scores, visual analogue scale (VAS) pain scores, and a minimum of 1-year follow-up. Patients were stratified into two cohorts. Cohort one patients had no prescription or over-the-counter PPI use (no PPI cohort). Cohort two patients had adherence to a long-term, high-dose, daily PPI (PPI cohort). RESULTS: Two hundred and eighty-one DRF patients were included. Of these 281 patients, 240 were in the no PPI cohort and 41 were in the PPI cohort. Patients in the PPI cohort had more median nerve injuries (12% versus 3%, p = 0.025) and radial shaft fractures (5% versus 0%, p = 0.020), less contralateral upper extremity injuries (0% versus 4%, p = 0.001), and more post-operative nonunions (7% versus 1%, p = 0.029) compared to patients in the no PPI cohort. CONCLUSIONS: Long-term, high-dose, daily PPI's may be associated with more median nerve injuries and radial shaft fractures, less contralateral upper extremity injuries, and more post-operative nonunions compared to DRF patients not on a PPI.

Intraoperative angiography imaging correlates with wound complications following soft tissue sarcoma resection.

For soft tissue sarcoma patients receiving preoperative radiation therapy, wound complications are common and potentially devastating. The purpose of this study was to assess the feasibility of intraoperative indocyanine green fluorescent angiography (ICGA) as a predictor of wound complications in these patients. A consecutive series of patients with soft tissue sarcoma of the extremities or pelvis who received neoadjuvant radiation and a subsequent radical resection received intraoperative ICGA with the SPY PHI device (Stryker Inc.) at the time of closure. Retrospective analysis of fluorescence signal along multiple points of the wound length was performed and quantified. The primary endpoint was wound complication, defined as delayed wound healing or wound dehiscence, within 3 months of surgery. Fourteen patients with preoperative irradiated soft tissue sarcoma were consecutively imaged. There were six patients with wound complications classified as "aseptic" in five cases. Using the ICGA, blinded surgeons correctly predicted wound complications in 75% of cases. During the inflow phase, a mean ratio of normal of 0.62 maximized the area under the curve (AUC = 0.90) for predicting wound complications with a sensitivity of 100% and specificity of 77.4%. During the peak phase, a mean ratio of normal of 0.55 maximized the AUC (0.95) for predicting wound complications with a sensitivity of 88.9% and a specificity of 100%. Intraoperative use of ICGA may help to predict wound complications in patients undergoing resection of preoperatively irradiated soft tissue sarcomas of the extremities and pelvis.

A Reliability Study of Multiplanar Radiographs for the Evaluation of SNAC Wrist Arthritis.

Background: Scaphoid nonunion advanced collapse (SNAC) is a common form of wrist arthritis, the treatment of which depends on the arthritic stage. The Vender classification serves to describe SNAC arthritis based on a single posteroanterior (PA) radiograph. The purpose of this study was to evaluate the intraobserver and interobserver agreement of the Vender classification, comparing multi versus single radiographic views. Methods: A retrospective review of patients with SNAC arthritis who underwent a proximal row carpectomy or a 4-corner fusion was performed. The included patients had 3 radiographic views of the pathologic wrist. Fifteen patients were analyzed by 5 blinded reviewers. Wrists were graded using the Vender classification first on the PA view and then using multiview radiographs. The intraobserver and interobserver agreement was determined using weighted kappa analysis. χ2 tests were calculated comparing the evaluation between single- versus multiview radiographs and determining a higher Vender stage. Results: Multiview radiographs demonstrated a higher intraobserver κw compared with single-view radiographs (0.72 vs 0.66), both representing substantial agreement. The average interobserver agreement was moderate (κw of 0.48) for single view and slight (κw of 0.30) for multiview evaluation. Evaluating multiview radiographs was 6.37 times more likely to demonstrate Vender stage 3 arthritis compared with single view (odds ratio = 6.37 [confidence interval, 3.81-10.64], P < .0001). Conclusion: Reviewing multiview radiographs more commonly yielded Vender stage 3 osteoarthritis classification. The decreased interrater reliability in the multiview analysis is likely related to the increased number of articular surfaces evaluated. Using a single PA view may underestimate the severity of arthritis present.

Return to Activities After Simultaneous Bilateral Endoscopic Carpal Tunnel Release.

BACKGROUND: Approximately 56% of patients diagnosed with carpal tunnel syndrome present with bilateral symptoms; however, few studies have investigated bilateral simultaneous endoscopic carpal tunnel release (ECTR) and postoperative effect on return to activity. The purpose of this study was to evaluate the length of recovery in patients who received bilateral simultaneous ECTR, including pain medication requirements, return to activities of daily living, return to work, and return to recreational activities. METHODS: A retrospective analysis was performed on patients who underwent bilateral ECTR by a single hand fellowship-trained surgeon from 2013 to 2019. Demographic, operative, and clinical outcomes were collected via chart review and a telephone interview. Student t tests and χ2 tests were conducted for analysis. RESULTS: Eighty patients were included in the study; 40 were successfully contacted for telephone interview follow-up. Patients reported an average of 2 days of use of postoperative narcotic pain medication and an average of 5, 7, and 19 days of return to activities of daily living, work, and recreational activities, respectively. Female patients reported more days of narcotic pain medications (1 day vs 3 days, P = .0483) and an average of longer return to work than men (9 days vs 5 days, P = .0477). Manual laborers reported longer return to work (9 days vs 5 days, P = .0500). Older patients (aged >65 years) reported longer return to recreational activities (39 days vs 11 days, P = .0189). CONCLUSIONS: Simultaneous bilateral ECTR is a successful procedure with shorter recovery times than reported previously. Female patients, manual laborers, and older patients experience a longer recovery and should be counseled appropriately.

Evaluating Treatment Preferences and Perceptions of a Prosthetic Versus a Transplanted Hand: A Conjoint Analysis-Based Study.

INTRODUCTION: This study used a conjoint analysis-based survey to assess which factors are most influential when considering treatment with a prosthesis or transplant after a unilateral hand amputation. METHODS: Overall, 469 respondents were recruited using Amazon Mechanical Turk and asked to assume that they experienced a hand amputation. To determine preferences for a prosthetic, respondents chose among 11 pairs of alternatives with variations in the following attributes: appearance, function, maintenance, and learning time. Respondents were then presented with descriptions of the risks and outcomes of hand transplantation. The most compelling reasons for and against a transplant were determined and characteristics predictive of support for a transplant were identified. RESULTS: The most important attributes for a prosthesis were "lifelike appearance" and "myolectric function." For hand transplantation, respondents were most concerned about immunosuppression side effects (n = 323, 69%) and the intense nature of surgery (n = 275, 59%), whereas the most positive benefit was the concept of the transplant being "natural" (n = 339, 72%). When faced with the choice of a hand transplant or a prosthetic, approximately 50% of respondents chose a transplantation. Younger age, previous medical experiences, a perceived "familiarity with medical issues," and the regular attendance of religious services were associated with strong support for a hand transplantation (P < 0.01). CONCLUSIONS: When considering a hand prosthesis, respondents are motivated most by appearance and function. Meanwhile, with hand transplantation, the risks of immunosuppression and the intense nature of surgery and recovery are predominant concerns. These findings may help inform patient-physician discussions when considering treatment after unilateral hand amputation.
