RESUMO

Septic, inflammatory, or crystal-induced arthritis are common etiologies of wrist pain without antecedent trauma associated with pain, loss of motion, swelling, redness, and warmth. In this report, we detail the case of granulocytic sarcoma of the wrist that presented as acute wrist pain, swelling, and limitation in motion. Granulocytic sarcoma is an exceedingly rare extramedullary tumor associated with acute myeloblastic leukemia. It may be found in any part of the body; however, upper extremity involvement is uncommon. To our knowledge, this is the first description of granulocytic sarcoma occurring in the wrist joint.

RESUMO

BACKGROUND: This study assessed the risk and factors of complications after volar locking plate fixation of distal radius fractures. METHODS: A single-institution retrospective review of patients undergoing volar locking plate fixation of distal radius fractures between May of 2000 and May of 2015 was undertaken. Demographic data, major complications, minor complications, and radiographic parameters were evaluated. RESULTS: Six hundred forty-seven distal radius fractures managed with volar plate fixation in 636 patients were reviewed. Mean follow-up was 9.1 months. Mean age was 56.5 years. Mean body mass index was 28.0, and 14.6 percent of patients had a body mass index greater than 35. Fractures were classified as Arbeitsgemeinschaft für Osteosynthesefragen class 23-C (67.2 percent), 23-A (26.6 percent), and 23-B (6.2 percent). The incidence of major and minor complications was 13.8 percent and 17.5 percent, respectively. The most common complication was transient paresthesia (9.7 percent). The incidence of tendon rupture or irritation was 0.5 percent or 2.5 percent, respectively. Hardware removal for painful/symptomatic hardware occurred in 6.2 percent at an average of 427.8 days after surgery. Major complications and minor complications were increased 2.2- and 1.9-fold, respectively, in patients with a body mass index greater than 35. Major complications were also increased 3.19 times in patients with residual intraarticular step-off. Hardware removal was 3.3 times more likely in patients with Soong grade 2 plate prominence and 2.9 times more likely in patients with a history of diabetes mellitus. CONCLUSIONS: Volar plate osteosynthesis of distal radius fractures is associated with an overall low complication rate. Patient factors, including diabetes mellitus and obesity, and intraoperative factors, including intraarticular fracture alignment and plate prominence, were associated with a higher rate of complications or revision surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

RESUMO

BACKGROUND: Currently, we lack objective measures to quantify outcomes in carpal tunnel syndrome. Instead, surgeons rely on patient-reported outcomes measures (PROMs) to assess the effect of carpal tunnel release (CTR). We assessed the validity and reliability of wearable activity monitors to objectively characterize the functional and sleep impact of CTR. We hypothesized that actigraphy could detect changes in sleep and activity and would demonstrate short-term impairment due the operative procedure. METHODS: This pilot, prospective, cohort study compared validated PROMS with actigraphy data obtained via wearable activity monitors (ActiGraph Link; ActiGraph Corp, Pensacola, Fla). Subjects completed baseline questionnaires and wore their device for 1 week preoperatively as a baseline. Subjects then underwent open CTR, wearing actigraphy devices for 4 weeks and completing questionnaires at 2 and 4 weeks postoperatively. Preintervention and postintervention data were compared using paired-sample t test. The Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire data were analyzed in accordance with published PROMIS scoring manuals and raw scores were converted to standardized T scores. RESULTS: Twenty subjects (5 males, 15 females) with moderate or severe carpal tunnel syndrome were enrolled. The mean age was 57.7 years. The PROMIS 29 average cumulative T score was 42.9 with average change of -0.072 preoperatively versus postoperatively. Average sleep disturbance T score was 38.9 preoperatively and 41.4 postoperatively. There was no statistically significant difference in T score in any domain. The mean actigraphy activity data demonstrated near immediate return to baseline activity. Actigraphy sleep data demonstrate improvement in sleep fragmentation and decreased duration of awakenings. CONCLUSIONS: Overall, patient-generated data detected differences in sleep and activity preoperatively versus postoperatively and demonstrated only a short period of activity disruption after CTR, which may be used when counseling patients. These data support actigraphy as a viable adjunct to traditional PROMS to evaluate the impact of surgical intervention and therefore may be useful in the study of other diseases affecting the upper extremity.

RESUMO

INTRODUCTION: Allograft tissue products have widespread applications across surgical specialties, but little data exist about surgeon attitudes toward the use of these products in the upper extremity. METHODS: Using a web-based survey, we sought to investigate the use of and feelings toward allograft products among hand surgeons. A short questionnaire was distributed to all active members of American Society for Surgery of the Hand as of October 2015 (N = 2,578). Demographic and practice setting information was collected. Additionally, questions concerning the use of human allograft tissue products of various types including bone, skin, and soft tissues were asked. RESULTS: Of 2,578 American Society for Surgery of the Hand members, 406 hand surgeons (15.8%) responded to the survey. A large majority (92%) reported having used allograft products in the upper extremity. Orthopedic-trained surgeons were more likely to have used bone and tendon allograft, whereas plastic and general surgery-trained surgeons were more likely to have used nerve and dermis allograft. Reduced donor site morbidity and complication rates were factors motivating surgeons to use allograft tissue. CONCLUSIONS: In spite of variation with respect to their use, allograft tissue products are popular and interest in new products, especially to improve flexor tendon pulley reconstruction, is high.

RESUMO

BACKGROUND: The purpose of this study is to assess the feasibility of a novel microporous annealed particle (MAP) scaffolding hydrogel to enable both articular cartilage and subchondral bone biointegration and chondrocyte regeneration in a rat knee osteochondral defect model. METHODS: An injectable, microporous scaffold was engineered and modified to match the mechanical properties of articular cartilage. Two experimental groups were utilized-negative saline control and MAP gel treatment group. Saline and MAP gel were injected into osteochondral defects created in the knees of Sprague-Dawley rats. Photo-annealing of the MAP gel was performed. Qualitative histologic and immunohistochemical analysis was performed of the treated defects at 2, 4, and 8 weeks postsurgery. RESULTS: The injectable MAP gel successfully annealed and was sustained within the osteochondral defect at each timepoint. Treatment with MAP gel resulted in maintained size of the osteochondral defect with evidence of tissue ingrowth and increased glycosaminoglycan production, whereas the control defects presented with evidence of disorganized scar tissue. Additionally, there was no significant inflammatory response to the MAP gel noted on histology. CONCLUSIONS: We have demonstrated the successful delivery of an injectable, flowable MAP gel scaffold into a rat knee osteochondral defect with subsequent annealing and stable integration into the healing wound. The flowable nature of this scaffold allows for minimally invasive application, for example, via an arthroscopic approach for management of wrist arthritis. The MAP gel was noted to fill the osteochondral defect and maintain the defect dimensions and provide a continuous and smooth surface for cartilage regeneration, suggesting its ability to provide a stable scaffold for tissue ingrowth. Future chemical, mechanical, and biological gel modifications may improve objective evidence of cartilage regeneration.

RESUMO

BACKGROUND: To assess the risk and factors of complications after volar locking plate fixation of distal radius fractures (VLPDR). METHODS: A single institution retrospective review of patients undergoing VLPDR between May 2000-May 2015 was undertaken. Demographic data, major complications, minor complications and radiographic parameters were evaluated. RESULTS: 647 distal radius fractures managed with volar plate fixation in 636 patients were reviewed. Mean follow-up was 9.1 months. Mean age was 56.5 years. Mean BMI was 28.0 and 14.6% of patients had a BMI greater than 35. Fractures were classified as AO class 23-C(67.2%), 23-A(26.6%) and 23-B(6.2%). The incidence of major and minor complications was 13.8% and 17.5%, respectively. The most common complication was transient paresthesia(9.7%). The incidence of tendon rupture or irritation was 0.5% or 2.5%, respectively. Hardware removal for painful/symptomatic hardware occurred in 6.2% at an average of 427.8 days post-surgery. Major complications and minor complications were increased 2.2 and 1.9 fold in patients with a BMI>35. Major complications were also increased 3.19 times in patients with residual intra-articular step off. Hardware removal was 3.3 times more likely in patients with Soong Grade 2 plate prominence and 2.9 times more likely in patients with a history of diabetes. CONCLUSIONS: Volar plate osteosynthesis of distal radius fractures is associated with an overall low-complication rate. Patient factors including diabetes and obesity as well as intra-operative factors including intra-articular fracture alignment and plate prominence were associated with a higher rate of complications or revision surgery.

RESUMO

BACKGROUND: The purpose of the present study was to identify trends in management and to compare the outcomes and complications following nonoperative and operative management (including external fixation, closed reduction and percutaneous pinning, and open reduction and internal fixation) for distal radial fractures in patients ≥65 years of age. METHODS: We performed a retrospective analysis, with use of the OptumLabs Data Warehouse database, of patients ≥65 years of age who had been managed for a distal radial fracture between 2009 and 2014 (as indicated by diagnosis codes according to the International Classification of Diseases, Ninth Revision, Clinical Modification). Ninety-day and 1-year complication rates per 1,000 fractures were analyzed overall and by treatment modality. RESULTS: Thirteen thousand, seven hundred and thirteen distal radial fractures were analyzed. The overall 90-day complication rate was 36.5 per 1,000 fractures, and the 1-year upper-extremity-specific complication rate was 236.2 and 307.5 per 1,000 fractures for nonoperative and operative management, respectively. Overall, post-injury stiffness was the most common 1-year upper-extremity-specific complication (incidence, 11.5%). There was no significant difference between operative and nonoperative management in terms of 90-day complication rates. However, operative management had a higher 1-year complication rate than nonoperative management (307.5 versus 236.2 per 1,000 fractures). Overall, the 5 most common upper-extremity-specific complications following operative treatment of distal radial fracture were stiffness (16.0%), chronic regional pain syndrome (9.9%), median neuropathy (8.0%), implant-related complications (3.8%), and tendon-related complications (2.8%). Stiffness was significantly more frequent following operative management (16.0% versus 9.8%; p < 0.01). CONCLUSIONS: Operative management of a distal radial fracture should be carefully considered when discussing treatment options with patients ≥65 years of age. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Background We designed a survey to ascertain the current perspectives of hand surgeons on the evaluation and management of ulnar nerve instability at the elbow. The secondary aim was to assess the concordance of hand surgeons on definitions of the terms "subluxated" and "dislocated" for classification of ulnar nerve instability. Methods A questionnaire, including demographic practice variables, cubital tunnel practice patterns, preoperative imaging and electrodiagnostic evaluation, and a series of standardized intraoperative photographs of ulnar nerve instability at the elbow were developed and distributed to the current American Society for Surgery of the Hand (ASSH) membership. Results A total of 690 (26.8%) members completed the survey; 84.2% of respondents indicated that they evaluate for ulnar nerve instability preoperatively with clinical examination, whereas only 6.1% indicated they routinely obtained dynamic ultrasound. Respondents indicated that the factors most strongly influencing their decision to proceed with anterior transposition of the ulnar nerve were subluxation on physical examination (89.6%), history consistent with ulnar nerve subluxation (85.8%), and muscle atrophy (43.2%). On review of clinical photographs, respondents demonstrated varying degrees of agreement on the terms "subluxated" or "dislocated" and recommendations for ulnar nerve transposition at intermediate degrees of ulnar nerve instability. Conclusion ASSH members routinely evaluate for ulnar nerve instability with history and clinical examination without uniform use of preoperative ultrasound, and nearly half of the time the decision to transpose the ulnar nerve is made intraoperatively. Definitions for the degree of ulnar nerve instability at the elbow are not uniformly agreed upon, and further development of a classification system may be warranted to standardize treatment.

RESUMO

BACKGROUND: The safety and feasibility of sterile, acellular pulley allografts in reconstruction has been previously demonstrated. Comparisons with tendon-based techniques for pulley reconstruction have not been reported. We hypothesized that the use of allograft pulleys would result in reduced procedural time and equivalent clinical outcomes as compared with traditional tendon-based reconstructive techniques. METHODS: All cases of pulley reconstruction using either allograft pulleys or tendon-based pulley reconstruction between November 2013 and November 2015 were reviewed. Patients who underwent concomitant procedures were excluded. Patient demographics, comorbidities, operative details (tourniquet and total operative times, number of pulleys repaired), postoperative complications (surgical site infection, reoperation, stiffness, and persistent pain), disability of the arm, shoulder and hand scores, and follow-up data were recorded. A P value of <0.05 was considered significant. RESULTS: Fifteen pulleys in 10 patients were reconstructed: 5 tendon-based and 5 with allograft. Average length of follow-up was 12.5 ± 2.9 months. There was no difference in patient demographic factors or comorbidities between groups. The most common indication for surgery was trauma. Four of 5 patients in the allograft group had multiple pulleys reconstructed versus 1 in the tendon-based group. One patient in the tendon-based group required reoperation versus 0 in the allograft group. Total operative and tourniquet times were significantly reduced in the allograft group (46 ± 5.5 vs 89 ± 12.9 minutes and 34 ± 6.8 vs 63 ± 5.3 minutes; P = 0.015 and 0.014). Postoperative disability of the arm, shoulder and hand scores were lower in the allograft group (56.8 vs 3.6, P = 0.11). There was no significant difference in postoperative range of motion between groups. CONCLUSION: Pulley reconstruction with allograft is an efficient, technically feasible, reconstructive technique that adheres to the principle of replacing like with like, while eliminating donor site morbidity. Overall operative and tourniquet times were significantly shorter using allograft pulleys for pulley reconstruction.

RESUMO

BACKGROUND: Acellular dermal matrices have revolutionized alloplastic breast reconstruction. Furthering our knowledge of their biointegration will allow for improved design of these biomaterials. The ideal acellular dermal matrix for breast reconstruction would provide durable soft-tissue augmentation while undergoing rapid biointegration to promote physiologic elasticity and reduced infectious complications. The inclusion of fenestrations in their design is thought to promote the process of biointegration; however, the mechanisms underlying this theory have not been evaluated. METHODS: Biointegration of standard and fenestrated acellular dermal matrices was assessed with serial photoacoustic microscopic imaging, in a murine dorsal skinfold window chamber model specifically designed to recapitulate the microenvironment of acellular dermal matrix-assisted alloplastic breast reconstruction. Photoacoustic microscopy allows for a serial, real-time, noninvasive assessment of hemoglobin content and oxygen saturation in living tissues, generating high-resolution, three-dimensional maps of the nascent microvasculature within acellular dermal matrices. Confirmatory histologic and immunohistochemical assessments were performed at the terminal time point. RESULTS: Fenestrated acellular dermal matrices demonstrated increased fibroblast and macrophage lineage host cell infiltration, greater mean percentage surface area vascular penetration (21 percent versus 11 percent; p = 0.08), and greater mean oxygen saturation (13.5 percent versus 6.9 percent; p < 0.05) than nonfenestrated matrices by 2 weeks after implantation. By 21 days, host cells had progressed nearly 1 mm within the acellular dermal matrix fenestrations, resulting in significantly more vascularity across the top of the fenestrated matrix (3.8 vessels per high-power field versus 0.07 vessels per high-power field; p < 0.05). CONCLUSIONS: Inclusion of fenestrations in acellular dermal matrices improves the recellularization and revascularization that are crucial to biointegration of these materials. Future studies will investigate the optimal distance between fenestrations.

RESUMO

Owing to its osteoinductive and osteoconductive properties and the presence of osteogenic cells, freshly harvested autologous bone graft is the gold standard for skeletal reconstruction where there is inadequate native bone. Whereas these characteristics are difficult to replicate, engineered, commercially available bone graft substitutes aim to achieve a comparable osseoregenerative profile. This work furnishes the reader with an understanding of the predominant classes of bone graft substitutes available for reconstruction of upper extremity bone defects following trauma or oncological surgery. We review bone graft substitutes with respect to their mechanisms of action, their advantages and disadvantages, and their indications and contraindications. We provide examples of bone graft substitutes in clinical use and outline comparative costs. We also describe the future directions for this specific aspect of reconstructive surgery with a focus on the role of bioactive glass.

RESUMO

Scaphoid fractures typically occur in young, healthy males at the peak of their employment and productivity, and left untreated or inadequately treated will ultimately progress to nonunion and a "predictable" pattern of wrist arthritis and carpal collapse. Nonoperative treatment of these fractures requires prolonged cast immobilization, which can lead to wrist stiffness, loss of grip strength, muscle atrophy, and protracted loss of economic productivity. To prevent these devastating sequelae, percutaneous techniques for scaphoid fixation have been described and popularized; however, these techniques are technically demanding as optimal position of the compression screw is required to achieve bony union. The focus of this paper is to describe the indications, contraindications, and a series of reproducible, practical pearls to achieve ideal percutaneous scaphoid compression screw fixation of scaphoid waist and distal pole fractures.

RESUMO

BACKGROUND: We sought to compare the functional outcomes, radiographic outcomes, and complications of trapeziectomy and flexor carpi radialis (FCR) to abductor pollicis longus (APL) side-to-side tendon transfer with or without suture-button suspensionplasty for thumb basilar joint arthritis. METHODS: Patients treated with and without suture-button suspensionplasty were compared over a 6-year period. Data were reviewed for complications and functional outcomes, including grip and pinch strength, range of motion, and visual analog scale (VAS) pain scores. Plain radiographs were independently reviewed at initial presentation and at final follow-up, including proximal phalanx length, trapezial space height, and trapezial height ratio. RESULTS: Seventy thumb arthroplasties were performed in 70 patients. Trapeziectomy with FCR-APL side-to-side tendon transfer was performed in 39 patients, and trapeziectomy with FCR-APL side-to-side tendon transfer with suture-button suspensionplasty was performed in 31 patients. Mean length of follow-up was 28.4 ± 3.9 and 23.8 ± 2.6 months, respectively. Postoperative grip, oppositional and appositional pinch strength, and VAS pain scores improved compared with preoperative values, but were not significantly different based on suture-button suspensionplasty. Percentage decline in trapezial space ratio was significantly different between groups at 36.7% and 20.4% for procedures with and without suture-button suspensionplasty, respectively indicating that the trapezial space was better maintained within the suture suspension cohort. The incidence of postoperative complications, including surgical site infection, paresthesias, reoperation, complex regional pain syndrome, and symptomatic subsidence, was not significantly different between groups. CONCLUSIONS: Trapeziectomy with FCR to APL side-to-side tendon transfer with and without suture-button suspensionplasty results in comparable improvement in pain, grip strength, and functional parameters. Suture-button suspensionplasty results in significantly greater preservation of trapezial space.

RESUMO

PURPOSE: Distal radioulnar joint (DRUJ) prostheses designed as semiconstrained devices aiming to replace the function of the ulnar head, sigmoid notch of the radius, and triangular fibrocartilage complex have demonstrated the capacity to restore the functional status of the DRUJ. However, soft tissue complications including tendons, nerves, and wounds, although documented, have not been the primary focus of prior reports. This study investigated short- to medium-term soft tissue complications after DRUJ semiconstrained implant arthroplasty. METHODS: We performed a retrospective review of patients undergoing semiconstrained DRUJ implant arthroplasty with clinical and radiological follow-up greater than 1 year. Data were reviewed with a focus on soft tissue complications after arthroplasty. RESULTS: Fifty DRUJ implant arthroplasties were performed over 10 years in 49 patients. Patients' average age was 47.8 years. Average duration of follow-up was 35.8 ± 3.7 months. A total of 46 patients underwent multiple operations before DRUJ arthroplasty. Postoperative pronosupination range of motion, grip strength, and visual analog scale pain scores were significantly improved after DRUJ arthroplasty. Wound-healing problems occurred in 11 arthroplasties; however, all wounds subsequently healed without operative intervention. Wound-related complications were significantly increased in patients with a history of rheumatoid arthritis or immunosuppression. Eighteen operations were required to address complications in 8 patients. Extensor tendinopathy was the most common indication for reoperation; 5 tenosynovectomy procedures were required in 4 wrists. A prominent screw requiring removal was identified in 3 cases of tenosynovitis. Periprosthetic fractures were identified in 3 wrists; 2 of these required reoperation for open treatment. Removal of hardware was required in 2 patients; these patients required 9 subsequent reoperations. CONCLUSIONS: Distal radioulnar joint arthrosis is a major problem and patients commonly undergo multiple reconstructive surgeries before DRUJ implant arthroplasty. No instances of wound-related complications or tendinopathy occurred in patients without previous surgeries, and wound-related complications occurred at a higher frequency with a history of rheumatoid arthritis or immunosuppression. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

RESUMO

BACKGROUND: Untreated or undertreated burns are commonly encountered by plastic surgeons on medical trips in India and represent a major cause of disability. We sought to utilize validated patient-reported outcomes instruments to identify the patient population with the greatest burn-related disability in order to appropriately allocate plastic surgery resources to those in greatest need. METHODS: The Quick Disability of the Arm, Shoulder, and Hand, RAND 36-Item Short Form Health Survey, and Burn-Specific Health Scale-Revised, Brief, and Adapted questionnaires were administered via an interpreter during a plastic surgery trip to Jharkhand, India, in January 2018. Demographics, comorbidities, and burn-specific history were recorded. RESULTS: Twenty-eight postburn patients were surveyed (mean age, 17.0 ± 9.2 years; male:female ratio, 1:2.5). Mean time from injury was 4.74 years. No patient had received formal, primary burn care. Mechanism of injury: flame (39%), oil (32%), scalding water (14%), and other (14%). Fifty-four percent were extremity burns; 25%, facial; and 18%, neck burns. The Burn-Specific Health Scale-Revised, Brief, and Adapted demonstrated that the most significantly impacted domains for all patients were body image and skin sensitivity, with more than 80% of patients complaining of issues with skin sensitivity. In addition, children (aged <18 years) had diminished body image domain scores. RAND SF-36 scores were lowest in the energy (73.1 ± 25.0) and general health (76.5 ± 13.8) domains, and females with extremity burns demonstrated statistically significant decreases in their physical limitation domain scores (85.9 ± 17.3, P < 0.05). Females with extremity burns also had statistically significant lower scores in the energy domain (64.09 ± 25.75) as compared with their male counterparts with extremity burns (100 ± 0, P = 0.045). In general, females scored lower than did males in multiple domains, and those results reached statistical significance in the energy (65.9 ± 24.6 vs 93.6 ± 10.9), emotional (77.2 ± 21.5 vs 95.4 ± 11.2), and general health domains (71.1 ± 11.9 vs 90.0 ± 7.5) with P < 0.05. Children demonstrated significantly diminished scores in the emotional (75.5 ± 24.6) and general health (79.1 ± 11.8) domains. CONCLUSION: These data demonstrate the significant impact on quality of life that untreated burns have in this population. Male and female children with extremity burns and adult women with extremity burns were most significantly affected in multiple domains. Consequently, children and adult women with extremity burns appear to be the patient cohort with the greatest opportunity to impact their quality of life. These data may be utilized to improve patient triage and resource allocation for future surgical trips but could also be of significant benefit to internal health agencies and ministries for the same purpose.

RESUMO

BACKGROUND: The purpose of this study was to determine whether prominent radial shaft screws in volar locked plating of distal radius fractures increase the risk of tendon irritation, tendon rupture, or hardware removal. METHODS: Patients who underwent volar locked plating of distal radius fractures from April 2002 to March 2016 with at least 6 months of follow-up were evaluated. Variables examined included demographics, extensor tendon irritation, extensor tendon rupture, and hardware removal. The most prominent cortical screws on postoperative lateral radiographs were identified and measured from the dorsal cortex of the radial shaft to the tip of the screw. RESULTS: In all, 261 distal radius fractures in 255 patients were identified. Thirty-nine patients (14.9%) underwent subsequent hardware removal at a mean 15.8 ± 18.6 months. Nine patients (3.45%) were found to have clinically significant extensor tendon irritation including one patient (0.38%) with extensor tendon rupture. The average screw was 1.48 mm proud of the dorsal radial cortex. In all, 22.6% of screws were greater than 2 mm proud. Comparing patients who underwent hardware removal with those who did not, there was no statistically significant difference in mean screw prominence or proportion of patients with screws greater than 2 mm. There was no statistically significant difference between shaft screw prominence and extensor tendon irritation. CONCLUSIONS: The effect of dorsal screw prominence of radial shaft screws is not significant. This study does not support the downsizing of prominent screws 2 mm or less.

RESUMO

BACKGROUND: In adults with lower trunk brachial plexus injury, proximal nerve surgery for restoration of prehension demonstrates poor outcomes secondary to long distances required for nerve regeneration and time-dependent degradation of motor endplates. Options for reconstruction are limited to distal tendon or nerve transfers and free-functioning muscle transfers. In this article, the authors describe the long-term outcomes of brachialis muscle-to-flexor digitorum profundus transfer to restore prehension in patients with traumatic lower trunk brachial plexus injuries. METHODS: Eighteen adult patients with lower trunk brachial plexus palsy underwent brachialis muscle-to-flexor digitorum profundus transfer with the goal of restoring rudimentary prehensile function at a single institution. The patients were followed throughout their recovery with functional outcomes and patient satisfaction ratings. RESULTS: Brachialis muscle transfer resulted in restoring modified British Medical Research Council grade 3 or better function in 11 of 18 patients and grade 4 function in eight of 18 patients. Eleven of the 18 patients demonstrated a postoperative functional grasp for assistance with activities of daily living. Overall patient satisfaction following brachialis muscle transfer was 56 percent. Patient preoperative wrist extension (p < 0.018) and finger extension (p < 0.029) strength correlated with improved outcomes, whereas concomitant upper extremity fracture (p < 0.023) was associated with poorer outcomes. CONCLUSIONS: Brachialis muscle transfer is an option for reconstruction of prehensile function in patients with lower trunk brachial plexus palsy with preserved wrist extension. Brachialis muscle transfer is particularly useful in patients who are poor candidates for microsurgical free-functioning muscle transfer for grasp; however, its functional outcomes are not universally successful. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

INTRODUCTION: Acellular dermal matrices have revolutionized abdominal wall reconstruction; however, device failure and hernia recurrence remain significant problems. Fascia grafts are a reconstructive adjunct with increased tensile strength compared with acellular dermal matrices; however, clinical use is limited by insufficient donor material and donor site morbidity. To this end, we investigate the biomechanical properties of human abdominal wall allografts (AWAs) consisting of the anterior rectus sheath from xiphoid to pubis. METHODS: After cadaveric procurement of 6 human AWAs, the tissue was divided horizontally and a matched-sample study was performed with specimens randomized to 2 groups: fresh, unprocessed versus processed with gamma irradiation and decellularization. Specimens were evaluated for physical properties, DNA content, tensile strength, and electron microscopy. RESULTS: All AWA donors were male, with a mean age of 55.2 years (range, 35-74 years). Procured AWAs had a mean length of 21.70 ± 1.8 cm, width of 14.30 ± 1.32 cm, and area of 318.50 cm, and processing resulted in a 98.3% reduction in DNA content. Ultimate tensile strength was significantly increased after tissue processing, and after subcutaneous implantation, processed AWA demonstrated 4-fold increased tensile strength compared with unprocessed AWAs. CONCLUSIONS: Acellular AWAs represent a novel reconstructive adjunct for abdominal wall reconstruction with the potential of replacing "like with like" without additional donor site morbidity or antigenicity.
