Management of Superficial and Deep Peroneal Nerve Neuromas with Targeted Muscle Reinnervation in Nonamputees: Operative Technique and Early Outcomes. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2024; 12:e5742. [PMID: 38623447 PMCID: PMC11018179 DOI: 10.1097/gox.0000000000005742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 02/20/2024] [Indexed: 04/17/2024]
Abstract
Background Targeted muscle reinnervation (TMR), a surgical technique developed by the senior authors that coapts proximal ends of nerves to distal motor nerves of adjacent muscles, has demonstrated efficacy in the treatment and prevention of neuroma pain. The objective of this study is to describe the surgical technique for TMR of the superficial peroneal nerve (SPN) and deep peroneal nerve (DPN) in nonamputee patients and provide data on postoperative functional outcomes. Methods A single-institution retrospective chart review was performed between March 2018 and April 2021. Patients were de-identified and included if they were nonamputees receiving TMR for pain in the peroneal nerve distribution. Data extracted included demographic information, symptoms before operation, relevant nerve coaptation, peri-, and postoperative complications, and long-term functional outcomes. Results Of the 19 patients reviewed, 11 patients underwent TMR of the SPN alone: eight had complete resolution of their symptoms; two indicated partial improvement in pain; and one patient had no improvement. Four patients underwent TMR of the DPN alone: two patients had complete resolution of their pain, and two patients had partial improvement with pain. Four patients underwent TMR of both the SPN/DPN: two patients had complete resolution of their symptoms, and two patients were noted to have significant improvement but had persistent pain from prior foot operations. Average follow-up time was 260 days. Conclusions TMR is a successful technique in the management of SPN and DPN neuroma pain. Our technique revealed excellent clinical outcomes, no procedure-specific complications, and improved subjective pain reports.

Abstract
Surgical procedures, including nerve reconstruction and end-organ muscle reinnervation, have become more prominent in the prosthetic field over the past decade. Primarily developed to increase the functionality of prosthetic limbs, these surgical procedures have also been found to reduce postamputation neuropathic pain. Today, some of these procedures are performed more frequently for the management and prevention of postamputation pain than for prosthetic fitting, indicating a significant need for effective solutions to postamputation pain. One notable emerging procedure in this context is the Regenerative Peripheral Nerve Interface (RPNI). RPNI surgery involves an operative approach that entails splitting the nerve end longitudinally into its main fascicles and implanting these fascicles within free denervated and devascularized muscle grafts. The RPNI procedure takes a proactive stance in addressing freshly cut nerve endings, facilitating painful neuroma prevention and treatment by enabling the nerve to regenerate and innervate an end organ, i.e., the free muscle graft. Retrospective studies have shown RPNI's effectiveness in alleviating postamputation pain and preventing the formation of painful neuromas. The increasing frequency of utilization of this approach has also given rise to variations in the technique. This article aims to provide a step-by-step description of the RPNI procedure, which will serve as the standardized procedure employed in an international, randomized controlled trial (ClinicalTrials.gov, NCT05009394). In this trial, RPNI is compared to two other surgical procedures for postamputation pain management, specifically, Targeted Muscle Reinnervation (TMR) and neuroma excision coupled with intra-muscular transposition and burying.

Abstract
Over the past decade, the field of prosthetics has witnessed significant progress, particularly in the development of surgical techniques to enhance the functionality of prosthetic limbs. Notably, novel surgical interventions have had an additional positive outcome, as individuals with amputations have reported neuropathic pain relief after undergoing such procedures. Subsequently, surgical techniques have gained increased prominence in the treatment of postamputation pain, including one such surgical advancement - targeted muscle reinnervation (TMR). TMR involves a surgical approach that reroutes severed nerves as a type of nerve transfer to "target" motor nerves and their accompanying motor end plates within nearby muscles. This technique originally aimed to create new myoelectric sites for amplified electromyography (EMG) signals to enhance prosthetic intuitive control. Subsequent work showed that TMR also could prevent the formation of painful neuromas as well as reduce postamputation neuropathic pain (e.g., Residual and Phantom Limb Pain). Indeed, multiple studies have demonstrated TMR's effectiveness in mitigating postamputation pain as well as improving prosthetic functional outcomes. However, technical variations in the procedure have been identified as it is adopted by clinics worldwide. The purpose of this article is to provide a detailed step-by-step description of the TMR procedure, serving as the foundation for an international, randomized controlled trial (ClinicalTrials.gov, NCT05009394), including nine clinics in seven countries. In this trial, TMR and two other surgical techniques for managing postamputation pain will be evaluated.

Persistent perineal sinus following proctocolectomy in the inflammatory bowel disease patient. JGH Open 2023; 7:740-747. [PMID: 38034049 PMCID: PMC10684985 DOI: 10.1002/jgh3.12983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 09/13/2023] [Accepted: 10/12/2023] [Indexed: 12/02/2023]
Abstract
Prolonged perineal wound healing following proctocolectomy in patients with inflammatory bowel disease (IBD) is a frustrating result for the medical team and patients who were hoping for improved quality of life. Prolonged healing, which lasts more than 6 months following proctocolectomy, is termed persistent perineal sinus (PPS) and typically necessitates further surgical management. Healing of the PPS is difficult due to the resulting "dead space" following proctocolectomy, necessitating the need to fill the void with viable tissue in an area with anatomic constraints. Here we provide a narrative review and comprehensively address the incidence, pathogenesis, and clinical and operative management of a PPS in patients with IBD following proctocolectomy. Operative methods discussed include surgical debridement, flap closure of the perineum, omental flap closure, and gracilis muscle transposition. It is necessary to further investigate and establish a gold standard of care for these patients.

Novel mesh suture may resist bone cutting seen with wire-based sternal closures. JTCVS Tech 2023; 20:130-137. [PMID: 37555027 PMCID: PMC10405315 DOI: 10.1016/j.xjtc.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/26/2023] [Accepted: 06/07/2023] [Indexed: 08/10/2023] Open
Abstract
OBJECTIVE Sternal dehiscence is frequently associated with wire-based closures cutting through fragile bone, allowing sternal motion, separation, and infection. We investigated whether bone cutting could be limited by using a newly available mesh suture with improved force distribution. METHODS Five sternal models were closed using 8 interrupted single sternal wires, double sternal wires, braided poly(ethylene terephthalate) sutures, single-wrapped mesh sutures, or double-wrapped mesh sutures. To simulate chest-wall forces, closed sternal models were pulled apart using 1020 N of axial force applied incrementally. Double sternal wire and double-wrapped mesh suture were further compared by closing 3 new models with each material and subjecting these models to cyclic loading cycles, simulating breathing and coughing. Image analysis of needle hole size measured "bone cutting" by each closure material and sternal distraction as a function of force. RESULTS All models exhibited maximal separation at the xiphoid. During axial loading, needle hole size increased 7.2% in the double-wrapped mesh suture model and 9.2% in the double-wire model. Single-wrapped mesh suture, single wires, and braided poly(ethylene terephthalate) extended needle hole size by 6.7%, 47.0%, and 168.3% of original size, respectively. The double-wire model resisted sternal distraction best, separating 0.285 cm at the xiphoid. During cyclic loading, mesh suture exhibited significantly less bone cutting (P = .02) than double wire, with comparable levels of sternal separation (P = .07). CONCLUSIONS Mesh suture may resist bone cutting seen in sternal wire closure in bone models with comparable distraction to currently used sternal closure methods.

Patient definitions of transplant success in upper extremity vascularized composite allotransplantation: A mixed-methods study. SAGE Open Med 2023; 11:20503121231184677. [PMID: 37465724 PMCID: PMC10350745 DOI: 10.1177/20503121231184677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 06/12/2023] [Indexed: 07/20/2023] Open
Abstract
Objective Upper extremity vascularized composite allotransplantation is an innovative treatment option for people with upper extremity amputations. Limited patient-relevant long-term outcomes data about transplant success may impede patients' informed treatment decision-making. We assessed perceptions of what constitutes upper extremity vascularized composite allotransplantation success among individuals with upper extremity amputations. Methods This multisite study entailed interviews and focus groups with individuals with upper extremity amputations and upper extremity vascularized composite allotransplantation candidates, participants, and recipients. We examined perceptions of transplant success and preferences for five upper extremity vascularized composite allotransplantation outcomes. Qualitative data were analyzed using thematic analysis; and quantitative data were analyzed using descriptive statistics. Results In all, 50 individuals participated in interviews (61.7% participation rate), and 37 participated in nine focus groups (75.5% participation rate). Most were White (72%, 73%), had a mean age of 45 and 48 years, and had a unilateral amputation (84%, 59%), respectively. Participants conceptualized upper extremity vascularized composite allotransplantation success as transplant outcomes: (1) restoring function and sensation to enable new activities; (2) accepting the transplanted limb into one's identity and appearance; (3) not having transplant rejection; (4) attaining greater quality of life compared to prosthetics; and (5) ensuring benefits outweigh risks. Participants rated their most important upper extremity vascularized composite allotransplantation outcomes as follows: not having transplant rejection, not developing health complications, grasping objects, feeling touch and temperature, and accepting the upper extremity vascularized composite allotransplantation into your identity. Conclusion Individuals with upper extremity amputations maintain several conceptions of vascularized composite allotransplantation success, spanning functional, psychosocial, clinical, and quality of life outcomes. Providers should address patients' conceptions of success to improve informed consent discussions and outcomes reporting for upper extremity vascularized composite allotransplantation.

Patient preferences of patient selection criteria for upper extremity vascularized composite allotransplantation: A qualitative study. SAGE Open Med 2023; 11:20503121231181236. [PMID: 37342616 PMCID: PMC10278401 DOI: 10.1177/20503121231181236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 05/25/2023] [Indexed: 06/23/2023] Open
Abstract
Background Upper extremity vascularized composite allotransplantation is a life-enhancing reconstructive treatment option that aims to improve recipients' quality of life and maximize function. This study assessed upper extremity vascularized composite allotransplantation patient selection criteria perceptions among individuals with upper extremity limb loss. The perceptions of individuals with upper extremity limb loss on patient selection criteria may enable vascularized composite allotransplantation centers to improve criteria to avoid mismatched expectations about the posttransplant vascularized composite allotransplantation experience and outcomes. Realistic patient expectations may increase patient adherence, improve outcomes, and reduce vascularized composite allotransplantation graft loss. Methods We conducted in-depth interviews with civilian and military service members with upper extremity limb loss and upper extremity vascularized composite allotransplantation candidates, participants, and recipients from three US institutions. Interviews assessed perceptions of patient selection criteria for suitability as a candidate for upper extremity vascularized composite allotransplantation. Thematic analysis was used to analyze qualitative data. Results A total of 50 individuals participated (66% participation rate). Most participants were male (78%), White (72%), with a unilateral limb loss (84%), and a mean age of 45 years. Six themes emerged regarding upper extremity vascularized composite allotransplantation patient selection criteria, including support for candidates who: (1) are of younger age, (2) are in good physical health, (3) have mental stability, (4) are willing to "put in the work," (5) have specific amputation characteristics, and (6) have sufficient social support. Patients had preferences about selecting candidates with unilateral versus bilateral limb loss. Conclusions Our findings suggest that numerous factors, including medical, social, and psychological characteristics, inform patients' perceptions of patient selection criteria for upper extremity vascularized composite allotransplantation. Patient perceptions of patient selection criteria should inform the development of validated screening measures that optimize patient outcomes.

Abstract
Enhanced recovery after surgery protocols have become increasingly adopted for autologous breast reconstruction, demonstrating improved quality of care and reduced hospital stays. Despite this, average length of stay remains over 3 days. We have found, in appropriately selected patients, hospital length of stay can be safely reduced to less than 48 hours. Methods Retrospective review was performed of patients who underwent microsurgical breast reconstruction by the senior author (M.H.) from April 2019 to December 2021. Demographics, operative details, length of stay, and postoperative complications are reported to assess for safety of discharge within 48 hours, with the primary outcome measure being flap loss. Results In total, 188 flaps were performed on 107 patients. Average age was 51.4 years (SD 10.1 years) with average BMI 26.6 kg/m2 (SD 4.8 kg/m2). Average length of stay was 1.97 days (SD 0.61 days), and 96 patients (89.7%) were discharged within 48 hours. Six flaps (3.2%) required operative takebacks. Five of the six (83.3%) takebacks occurred on postoperative days zero or one, and all five of these flaps were salvaged. There were four breast hematomas (2.1%), four breast seromas (2.1%), eight breast infections (4.3%), 13 breasts (6.9%) with wound dehiscence, four flaps (2.1%) with partial flap loss, and 24 breasts (12.8%) with mastectomy flap necrosis. One hundred fifty flaps (79.8%) had no complications. Overall success rate of flap reconstruction was 99.5%. Conclusion Hospital discharge in 24-48 hours is safe in appropriately selected patients undergoing autologous tissue breast reconstruction.

Abstract
Amputations have been performed with few modifications since the dawn of surgery. Blood vessels are ligated, bones are shortened, and nerves are cut. In a percentage of people, this can result in severe neuropathic, residual limb, and phantom limb pain. Targeted muscle reinnervation is a surgical procedure initially conceived to optimize function for myoelectric prostheses in amputees. Recently, it has been adopted more widely by surgeons for the prevention and treatment of neuropathic pain. Perhaps as a function of its relatively recent development, many authors perform this operation differently, and there has been no overall agreement regarding the principles, indications, technical specifics, and postoperative management guidelines. This article is written as a consensus statement by surgeons focused on the treatment of neuropathic pain and those with extensive experience performing targeted muscle reinnervation. It is designed to serve as a roadmap and template for extremity surgeons to consider when performing targeted muscle reinnervation.

Abstract
Umbilical hernia repair is a common surgical procedure without a universally accepted means of repair. We introduce a novel surgical technique for open primary umbilical hernia repair, using strips of polypropylene mesh as sutures to achieve a repair. Methods Two-centimeter-wide strips of macroporous polypropylene mesh were passed through the abdominal wall and tied as simple interrupted sutures to achieve umbilical hernia repair. A retrospective review of all elective umbilical hernia repairs performed by a single surgeon using the mesh strip technique between 2016 and 2021 was conducted, and patient-reported outcomes were assessed via a telephonic survey. Results Thirty-three patients underwent an elective, open mesh strip repair of a primary umbilical hernia and met criteria for inclusion in the study. Of these patients, 60% responded to a patient-reported outcomes telephone survey. Ninety percent of survey responders reported a pain score of 0 of 10. Additionally, 90% reported being unable to feel or palpate the knot, and 80% reported an improvement in quality of life. Mean follow-up at 3 years revealed one recurrence in the setting of ascites, yielding a recurrence rate of 3%. Conclusion Primary mesh strip repair of umbilical hernias combines the simplicity of suture repair with the advantageous force distribution properties of mesh, and constitutes a safe, efficient, and effective method of repair with a low recurrence rate at long-term follow-up that is comparable to planar mesh repair.

Myoelectric prosthesis hand grasp control following targeted muscle reinnervation in individuals with transradial amputation. PLoS One 2023; 18:e0280210.

Abstract
BACKGROUND Despite the growing availability of multifunctional prosthetic hands, users' control and overall functional abilities with these hands remain limited. The combination of pattern recognition control and targeted muscle reinnervation (TMR) surgery, an innovative technique where amputated nerves are transferred to reinnervate new muscle targets in the residual limb, has been used to improve prosthesis control of individuals with more proximal upper limb amputations (i.e., shoulder disarticulation and transhumeral amputation). OBJECTIVE The goal of this study was to determine if prosthesis hand grasp control improves following transradial TMR surgery. METHODS Eight participants were trained to use a multi-articulating hand prosthesis under myoelectric pattern recognition control. All participated in home usage trials pre- and post-TMR surgery. Upper limb outcome measures were collected following each home trial. RESULTS Three outcome measures (Southampton Hand Assessment Procedure, Jebsen-Taylor Hand Function Test, and Box and Blocks Test) improved 9-12 months post-TMR surgery compared with pre-surgery measures. The Assessment of Capacity for Myoelectric Control and Activities Measure for Upper Limb Amputees outcome measures had no difference pre- and post-surgery. An offline electromyography analysis showed a decrease in grip classification error post-TMR surgery compared to pre-TMR surgery. Additionally, a majority of subjects noted qualitative improvements in their residual limb and phantom limb sensations post-TMR. CONCLUSIONS The potential for TMR surgery to result in more repeatable muscle contractions, possibly due to the reduction in pain levels and/or changes to phantom limb sensations, may increase functional use of many of the clinically available dexterous prosthetic hands.

Abstract
In the United States, an estimated 185,000 individuals undergo amputation of their upper or lower limb. This results in residual limb pain in up to 85% of cases. Targeted muscle reinnervation (TMR) is a technique that has been shown to prevent symptomatic neuroma formation. In this video, the authors demonstrate their technique utilizing TMR at the time of above-the-knee amputation. Coaptations are made to provide motor targets for branches of the saphenous, tibial, and peroneal sensory nerves. At the featured patient's most recent follow-up visit 3 months postoperatively, she reported no stump pain or phantom limb pain.

Abstract
With the increasing availability of more advanced prostheses individuals with a transradial amputation can now be fit with single to multi-degree of freedom hands. Reliable and accurate control of these multi-grip hands still remains challenging. This is the first multi-user study to investigate at-home control and use of a multi-grip hand prosthesis under pattern recognition and direct control. Individuals with a transradial amputation were fitted with and trained to use an OSSUR i-Limb Ultra Revolution with Coapt COMPLETE CONTROL system. They participated in two 8-week home trials using the hand under myoelectric direct and pattern recognition control in a randomized order. While at home, participants demonstrated broader usage of grips in pattern recognition compared to direct control. After the home trial, they showed significant improvements in the Assessment of Capacity for Myoelectric Control (ACMC) outcome measure while using pattern recognition control compared to direct control; other outcome measures showed no differences between control styles. Additionally, this study provided a unique opportunity to evaluate EMG signals during home use. Offline analysis of calibration data showed that users were 81.5% [7.1] accurate across a range of three to five grips. Although EMG signal noise was identified during some calibrations, overall EMG quality was sufficient to provide users with control performance at or better than direct control.

Suturable Mesh Demonstrates Improved Outcomes over Standard Suture in a Porcine Laparotomy Closure Model. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3879.

Abstract
Background: Laparotomy closures fail due to suture pull-through. I hypothesize that a suturable mesh may limit pull-through via mechanisms of force distribution and fibrous encapsulation of the device filaments. Methods: Fifteen domestic swine 74 kg in size were randomly allocated to three groups for laparotomy closure with either size 0 suturable mesh, number 1 suturable mesh, or number 1 polypropylene. All three devices were placed in running fashion with 1-cm bites and 1-cm travels. Primary endpoints were hernia formation at 13 weeks and a semiquantitative analysis of the histological tissue response. Secondary endpoints included adhesions, surgical site occurrence (SSO), and documentation of “loose sutures.” Results: There were numerically fewer hernias in the number 1 suturable mesh group. Nine of the 10 suturable mesh devices were well encapsulated within the tissues and could not be pulled away, whereas four of the five polypropylene sutures were loose. Adhesions were least for number 1 suturable mesh. Histologically, the suturable mesh implanted devices showed good fibrovascular ingrowth and were judged to be “nonirritants.” The soft-tissue response was statistically greater (P = 0.006) for the number 1 suturable mesh than for the number 1 polypropylene. Conclusions: The mechanism by which meshes support closure sites is clearly demonstrated with this model. Suturable mesh has the potential to change surgical algorithms for abdominal wall closure.

Ultrasound-Guided Lateral Abdominal Wall Botulinum Toxin Injection Before Ventral Hernia Repair: A Review for Radiologists. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2021; 40:2019-2030. [PMID: 33320354 DOI: 10.1002/jum.15591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 11/05/2020] [Accepted: 11/17/2020] [Indexed: 06/12/2023]
Abstract
Preoperative ultrasound-guided lateral abdominal wall botulinum toxin injection is a promising method for improving patient outcomes and reducing recurrence rates after ventral hernia repair. A review of the literature demonstrates variability in the procedural technique, without current standardization of protocols. As radiologists may be increasingly asked to perform ultrasound-guided botulinum toxin injections of the lateral abdominal wall, familiarity with the procedure and current literature is necessary.

Abstract
Purpose Meshes clearly have improved outcomes for tissue approximation over suture repairs for incisional hernias. A knowledge gap exists as to the surgical complication rate and post-operative outcomes of a mesh rectus diastasis repair with a narrow well-fixed mesh that simultaneously narrows the rectus muscles and closes the widened linea alba. Methods Inclusion criteria for mesh abdominoplasty were patients who (1) underwent a retrorectus planar mesh for repair of rectus diastasis (2) did not have a concurrent incisional hernia and (3) underwent skin tailoring as part of a cosmetic aspect of their care. The primary endpoint was surgical site occurrence (SSO) at any time after surgery as determined with review of their office and hospital medical records. Secondary endpoints included the length and complexity of the return to the operating room for any reason, non-surgical complications, readmission, post-operative recovery, surgical site infection, recurrence/persistence of abdominal wall laxity, and soft tissue revision rates. Results SSO rate was 0% for the 56 patients who underwent this procedure. There were 40 women and 16 men. Superficial infections requiring oral antibiotics were required in three patients. One was a drain site erythema, one was for a superficial stitch abscess, and the third was for a mesh strip knot infection 6 months after the procedure. One patient underwent further tightening of the abdominal wall. Rates of soft tissue revision in the office for improved cosmesis were 23% in women and 6% in men. Conclusion Repair of rectus diastasis with a narrow well-fixed mesh and concurrent skin abdominoplasty is a well-tolerated and reliable procedure with low recurrence and low SSO in the manner described. It is a procedure that works for both female and male pattern rectus diastasis, and has become our procedure of choice for moderate and severe rectus diastasis.

[PMID: 34367851 PMCID: PMC8337067 DOI: 10.1097/gox.0000000000003721] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 05/27/2021] [Indexed: 12/11/2022]
Abstract
Concerns regarding infection, extrusion, and pain have traditionally precluded the use of mesh to treat severe rectus diastasis during abdominoplasty in the United States. We describe a mesh abdominoplasty technique, and we hypothesize that the complication rate using mesh is greater than the complication rate of suture plication. METHODS Inclusion criteria for mesh abdominoplasty were patients who (1) had retrorectus planar mesh for repair of rectus diastasis, (2) did not have concurrent ventral hernia, and (3) underwent skin tailoring. Patients who underwent rectus plication with suture, and met criteria 2 and 3 above were included in a sample of consecutive standard abdominoplasty patients. The primary endpoint was surgical site occurrence at any time after surgery, as determined with review of their office and hospital medical records. Secondary endpoints included surgical site infection, revision rates, postoperative course, and aesthetics assessed with their last set of office photographs. RESULTS Surgical site occurrence rate was 0% of the 40 patients in the mesh group and 19% of the 37 patients in the standard group (P = 0.005); rates of soft-tissue revision were 23% in the mesh group and 27% in the standard group (P = 0.84). As to aesthetics, the mesh abdominoplasty patients had mean statistically lower preoperative scores in comparison with the standard plication group (65.8 ± 11.6 versus 70.3 ± 11.4, P = 0.0013). The mesh group had a statistical improvement to 75.9 ± 12.6 (P < 0.0001), whereas the standard plication group improved to 82.5 ± 11.4 (P < 0.0001). CONCLUSIONS Retrorectus mesh placement in a cohort of patients with severe rectus diastasis had a complication rate lower than that seen in a cohort of patients with less severe rectus diastasis, therefore negating our original hypothesis. This was done without compromising aesthetic improvement.

Kiteboarding Induced Abdominal Wall Pain: Intercostal Neuroma versus Anterior Cutaneous Nerve Entrapment (ACNES). PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3487. [PMID: 33747695 PMCID: PMC7963503 DOI: 10.1097/gox.0000000000003487] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 01/21/2021] [Indexed: 12/14/2022]
Abstract
Abdominal wall pain can be challenging to diagnose and treat, as many etiologies can have similar presentations. Anterior cutaneous nerve entrapment syndrome has been reported to be a significant cause of AWP. Here, we report the case of a patient who was initially diagnosed with anterior cutaneous nerve entrapment syndrome and ultimately found to have intercostal neuromas-in-continuity. The patient was a healthy 36-year-old man who presented with debilitating, chronic abdominal wall pain. The pain began after a time period when the patient was regularly kiteboarding, and it impacted the ability to exercise and perform activities of daily living. The patient had undergone extensive testing and attempted many treatments, including medication, nerve blocks, and anterior cutaneous nerve entrapment syndrome surgery. Examination was significant for 2 near-symmetric areas that were persistently tender to palpation in the subcostal abdomen. The patient underwent excision and reconstruction with two 2-cm segments of processed nerve allograft. At 1-year follow-up, the patient reported complete alleviation of the pain, discontinuation of pain medication, and a return to all normal activities. While managing patients with abdominal wall pain, physicians must consider neuroma in their differential diagnoses and be aware of its treatment options, as the patient underwent a substantial delay in treatment. Kiteboarding is a unique mechanism of peripheral nerve injury that has not been previously reported in the literature. This report demonstrates the efficacy of processed nerve allograft in the management of neuromas-in-continuity of the abdominal wall, as well as the importance of being aware of unusual manners of nerve injury.

Targeted Muscle Reinnervation at the Time of Upper-Extremity Amputation for the Treatment of Pain Severity and Symptoms. J Hand Surg Am 2021; 46:72.e1-72.e10. [PMID: 33268236 DOI: 10.1016/j.jhsa.2020.08.014] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Revised: 06/10/2020] [Accepted: 08/05/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE Targeted muscle reinnervation (TMR) is a technique for the management of peripheral nerves in amputation. Phantom limb pain (PLP) and residual limb pain (RLP) trouble many patients after amputation, and TMR has been shown to reduce this pain when performed after the initial amputation. We hypothesize that TMR at the time of amputation may improve pain for patients after major upper-extremity amputation. METHODS We conducted a retrospective review of patients who underwent major upper-extremity amputation with TMR performed at the time of the index amputation (early TMR). Phantom limb pain and RLP intensity and associated symptoms were assessed using the numeric rating scale (NRS), the Patient-Reported Outcome Measurement Information System (PROMIS) Pain Intensity Short-Form 3a, the Pain Behavior Short-Form 7a, and the Pain Interference Short-Form 8a. The TMR cohort was compared with benchmarked data from a sample of upper-extremity amputees. RESULTS Sixteen patients underwent early TMR and were compared with 55 benchmark patients. More than half of early TMR patients were without PLP (62%) compared with 24% of controls. Furthermore, half of all patients were free of RLP compared with 36% of controls. The median PROMIS PLP intensity score for the general sample was 47 versus 38 in the early TMR sample. Patients who underwent early TMR reported reduced pain behaviors and interference specific to PLP (50 vs 53 and 41 vs 50, respectively). The PROMIS RLP intensity score was lower in patients with early TMR (36 vs 47). CONCLUSIONS This study demonstrates that early TMR is a promising strategy for treating pain and improving the quality of life in the upper-extremity amputee. Early TMR may preclude the need for additional surgery and represents an important technique for peripheral nerve surgery. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Targeted muscle reinnervation at the time of amputation in the management of complex regional pain syndrome of the lower extremity. Microsurgery 2020; 40:852-858. [PMID: 32965061 DOI: 10.1002/micr.30653] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Revised: 07/29/2020] [Accepted: 09/03/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND Complex regional pain syndrome (CRPS) is a chronic, posttraumatic condition defined by severe pain and sensorimotor dysfunction. In cases of severe CRPS, patients request amputation, which may cause phantom limb pain (PLP) and residual limb pain (RLP). Targeted muscle reinnervation (TMR) reduces the risk of PLP and RLP. This report describes the use of TMR at the time of amputation in a series of patients with CRPS. PATIENTS AND METHODS Four patients (ages 38-71 years) underwent TMR at the time of amputation for CRPS between April 2018 and January 2019. Three patients had a history of trauma and surgery to the affected limb. All patients attempted pharmacologic and interventional treatments for 1-7 years before requesting amputation. Three patients underwent below-knee amputations (BKA) and one had an above-knee amputation (AKA). Target muscles included the soleus, gastrocnemius, and flexor hallucis longus (BKA), and semitendinosus, biceps femoris, and vastus medialis (AKA). Postoperative phantom and residual limb pain symptoms were collected via a telephone survey adapted from the Patient-Reported Outcomes Measurement Information System (PROMIS). RESULTS There were no complications related to the TMR procedure. Average follow-up time was 12.75 months. Patients reported varied outcomes: two had RLP and PLP, one had RLP only, and one had PLP only. All patients reported successful prosthetic use. CONCLUSION TMR may be performed at the time of amputation for CRPS. Further study is necessary to determine the effect of TMR on pain, pain medication use, prosthesis use, and other domains of function.

Benchmarking Residual Limb Pain and Phantom Limb Pain in Amputees through a Patient-reported Outcomes Survey. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e2977. [PMID: 32802669 PMCID: PMC7413780 DOI: 10.1097/gox.0000000000002977] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Accepted: 05/22/2020] [Indexed: 11/26/2022]
Abstract
More than 75% of major limb amputees experience chronic pain; however, data on severity and experience of pain are inconsistent. Without a benchmark using quantitative patient-reported outcomes, it is difficult to critically assess the efficacy of novel treatment strategies. Our primary objective is to report quantitative pain parameters for a large sample of amputees using the validated Patient-reported Outcomes Measurement System (PROMIS). Secondarily, we hypothesize that certain patient factors will be associated with worse pain. METHODS PROMIS and Numerical Rating Scales for residual limb pain (RLP) and phantom limb pain (PLP) were obtained from a cross-sectional survey of upper and lower extremity amputees recruited throughout North America via amputee clinics and websites. Demographics (gender, age, race, and education) and clinical information (cause, amputation level, and time since amputation) were collected. Regression modeling identified factors associated with worse pain scores (P < 0.05). RESULTS Seven hundred twenty-seven surveys were analyzed, in which 73.4% reported RLP and 70.4% reported PLP. Median residual PROMIS scores were 46.6 [interquartile range (IQR), 41-52] for RLP Intensity, 56.7 (IQR, 51-61) for RLP Behavior, and 55.9 (IQR, 41-63) for RLP Interference. Similar scores were calculated for PLP parameters: 46.8 (IQR, 41-54) for PLP Intensity, 56.2 (IQR, 50-61) for PLP Behavior, and 54.6 (IQR, 41-62) for PLP Interference. Female sex, lower education, trauma-related amputation, more proximal amputation, and closer to time of amputation increased odds of PLP. Female sex, lower education, and infection/ischemia-related amputation increased odds of RLP. CONCLUSION This survey-based analysis provides quantitative benchmark data regarding RLP and PLP in amputees with more granularity than has previously been reported.

Abstract
BACKGROUND Conventional reconstructive options for large full-thickness eyelid defects are limited to static local flaps without replacing the missing orbicularis. The authors' aim is to delineate the platysma neurovascular anatomy for innervated functional eyelid reconstruction. METHODS Fourteen fresh latex-injected heminecks were dissected. The locations where neurovascular structures entered the platysma muscles were expressed as the percentage distance ± SD from the sternocleidomastoid muscle mastoid insertion to manubrium origin. RESULTS The superior thyroid, facial, and lingual vessels were the major pedicles in eight of 14 (57.1 percent), four of 14 (28.6 percent), and one of 14 specimens (7.1 percent), respectively. In one specimen (7.1 percent), both the superior thyroid and facial vessels supplied a major pedicle. Venous drainage generally mirrored arterial inflow but was redundant, with 43 percent and 14 percent of flaps also with major contributions from the external jugular and anterior jugular veins, respectively. Neurovascular pedicles entered the platysma 28 to 57 percent caudal to the sternocleidomastoid muscle mastoid insertion, between 0.5 and 4.8 cm anterior to the medial sternocleidomastoid muscle border. CONCLUSION Although variability exists, platysma neurovascular pedicles enter at predictable locations between 28 and 57 percent of the distance from the mastoid insertion of the sternocleidomastoid muscle, therefore making free platysma transfer a feasible option for eyelid reconstruction.

Abstract
Objective: Upper limb transplantation provides a new restorative option for individuals with amputations. As true for most operations, patient selection is critical to optimizing transplantation outcomes. To improve on the patient selection process, we used qualitative methods to better understand the issues regarding upper extremity loss as well as upper limb transplantation from the amputee point of view. Methods: Individuals with upper limb amputations (age range = 24–73 years) discussed their adjustment following amputation and their interest toward transplantation in either a focus group (n = 5) or semi-structured interview (n = 17). Transcripts were coded by theme and summarized. Results: Participants described a year-long process typified by adjustment to a new role as an amputee, both psychosocially and functionally. We found that the extent of adjustment was inversely related to an interest in transplantation. Conclusions: These findings could explain the difficulty in identifying “ideal” candidates for upper extremity transplantation and may have implications for patient selection and counseling.

Abstract
BACKGROUND We describe a multidisciplinary approach for comprehensive care of amputees with concurrent targeted muscle reinnervation (TMR) at the time of amputation. METHODS Our TMR cohort was compared to a cross-sectional sample of unselected oncologic amputees not treated at our institution (N = 58). Patient-Reported Outcomes Measurement Information System (NRS, PROMIS) were used to assess postamputation pain. RESULTS Thirty-one patients underwent amputation with concurrent TMR during the study; 27 patients completed pain surveys; 15 had greater than 1 year follow-up (mean follow-up 14.7 months). Neuroma symptoms occurred significantly less frequently and with less intensity among the TMR cohort. Mean differences for PROMIS pain intensity, behavior, and interference for phantom limb pain (PLP) were 5.855 (95%CI 1.159-10.55; P = .015), 5.896 (95%CI 0.492-11.30; P = .033), and 7.435 (95%CI 1.797-13.07; P = .011) respectively, with lower scores for TMR cohort. For residual limb pain, PROMIS pain intensity, behavior, and interference mean differences were 5.477 (95%CI 0.528-10.42; P = .031), 6.195 (95%CI 0.705-11.69; P = .028), and 6.816 (95%CI 1.438-12.2; P = .014), respectively. Fifty-six percent took opioids before amputation compared to 22% at 1 year postoperatively. CONCLUSIONS Multidisciplinary care of amputees including concurrent amputation and TMR, multimodal postoperative pain management, amputee-centered rehabilitation, and peer support demonstrates reduced incidence and severity of neuroma and PLP.

Abstract
Over one million amputations occur annually world-wide. Often, amputation of the neoplastic limb is regarded as a surgical failure and the end of surgical care for the patient. Here, we highlight the advancements in extremity prostheses and surgical techniques that should change that mindset. Myoelectric prostheses, osseointegration, and targeted muscle reinnervation allow for more intuitive and easy to use devices, reduced pain, and greater quality of life for amputees.

Abstract
BACKGROUND We sought to evaluate the results of a new mesh sutured repair technique for closure of contaminated incisional hernias. METHODS 48 patients with contaminated hernias 5 cm wide or greater by CT scan were closed with mesh sutures. Surgical site occurrence, infections, and hernia recurrence were compared to similar patient series reported in the literature. RESULTS Of the 48 patients, 20 had clean-contaminated wounds, 16 had contaminated wounds, and 12 were infected. 69% of the patients underwent an anterior perforator sparing components release for hernias that averaged 10.5 cm transversely (range 5 cm-25 cm). SSO occurred in 27% of patients while SSI was 19%. There were no fistulas or delayed suture sinuses. With a mean follow-up of almost 12 months, 3 midline hernias recurred (6%). In these same patients, three parastomal hernias repaired with mesh sutures failed out of 4 attempted for a total failure rate of 13%. CONCLUSION Mesh sutured closure represents a simplified and effective surgical strategy for contaminated midline incisional hernia repair.

Abstract
BACKGROUND Localized nerve pain in the foot and ankle can be a chronic source of disability after trauma and has been identified as the most common complication following operative interventions in the foot and ankle. The superficial location of the injured nerves and lack of suitable tissue for nerve implantation make this pain refractory to conventional methods of neuroma management. We describe a novel strategy for management using processed nerve allografts to bridge nerve gaps created by resection of both end neuromas and neuromas-in-continuity. METHODS A retrospective review of a prospectively maintained database was performed of all patients who received a processed nerve allograft for treatment of painful neuromas in the foot and ankle between May 2010 and June 2015. Patient demographic and operative information was obtained, as well as preoperative and postoperative pain assessments using a conventional ordinal scale and PROMIS (Patient Reported Outcomes Measurement Information System) Pain Behavior and Pain Interference assessments. Twenty-two patients were identified, with postoperative pain assessments occurring at a mean of 15.5 months after surgery. RESULTS Neuromas of the sural and superficial peroneal nerves were the most common diagnoses, with 3-cm nerve allografts being used as the interposition graft in the majority of cases. Eight patients had end neuromas and 18 patients had neuromas in continuity. Analysis of paired data demonstrated a mean ordinal pain score decrease of 2.6, with 24 and 31 percentage-point decreases in PROMIS Pain Behavior and Pain Interference measures, respectively. All changes were significant (P < .002). CONCLUSION The painful sequelae of superficial nerve injuries in the foot and ankle was significantly improved with complete excision of the involved nerve segment followed by bridging of the resulting nerve gap with a processed nerve allograft. This approach limits surgery to the site of injury and reconstitutes the peripheral nerve anatomy. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND Our objective was to determine outcomes for complex ventral hernia repairs in a large cohort of patients utilizing an operative construct employing retrorectus placement of a narrow, macroporous polypropylene mesh with up to 45 suture fixation points for force distribution. No consensus exists on the optimal technique for repair of complex ventral hernias. Current trends emphasize large meshes with wide overlaps and minimal suture fixation, though reported complications and recurrence remain problematic. METHODS A retrospective review was performed for all patients undergoing ventral hernia repair with retrorectus placement of midweight, uncoated, soft polypropylene mesh by a single surgeon (GAD) between the years of 2010 and 2015. Patient characteristics, operative history, operative data, and postoperative course were reviewed. RESULTS A total of 101 patients with a mean age of 56 years and a mean body mass index of 29 m/kg2 (range 18-51 m/kg2) underwent hernia repair. Patients had a median of 3 prior abdominal operations (range 0-9), with 44 patients presenting with recurrent hernias. A total of 42 patients were Ventral Hernia Working Group grade 1, 40 grade 2, 17 grade 3, and 2 grade 4. There were no recurrences at a mean follow-up of almost 400 days for the 93 patients with long-term follow-up. The surgical site occurrence rate was 7.9% (3 surgical site infections, 2 seromas, 2 hematomas, and 4 instances of delayed wound healing in 8 patients). One patient required reoperation for hematoma drainage; 5 patients required readmission within 30 days. CONCLUSION An operative construct employing a retrorectus placement of a narrow, macroporous polypropylene mesh with up to 45 suture fixation points for force distribution can achieve significantly better outcomes across a spectrum of Ventral Hernia Working Group grade, risk-stratified patients compared to rates reported in the literature for current strategies that employ wide meshes with minimal fixation.

Abstract
BACKGROUND The Patient-Reported Outcomes Measurement Information System was used to evaluate the effects of open incisional ventral hernia repair on hernia-related pain. METHODS All patients who underwent elective repair of a primary or recurrent midline incisional hernia over a 3-year period completed Patient-Reported Outcomes Measurement Information System pain surveys and rated their pain intensity on a visual analogue scale. A retrospective review of these patients was performed. RESULTS Seventy-seven patients underwent midline incisional ventral hernia repair and completed preoperative and postoperative surveys. Thirty-eight patients completed surveys at least 6 months after surgery. These patients demonstrated significant improvement in pain interference postoperatively (P < .05) but not in pain behavior. Patients with higher pain intensity scores preoperatively had greater improvements in pain behavior and pain interference postoperatively. CONCLUSIONS Patients with incisional ventral hernias have improvement in pain interference 6 months after open surgical repair. Changes are most pronounced in patients who experience higher magnitudes of pain preoperatively.

STUDY AND DESIGN AND SETTING: In our consecutive series of 114 patients, 44 patients had prior head and neck irradiation. The 2 groups were compared on the basis of age, ischemic time, and flap size and were found not to be statistically different. The average ischemic time for the irradiated group was 94.1 minutes, and the average was 102.8 minutes for the nonirradiated group. The average flap size for the irradiated group was 69.5 cm 2 , and was 72.0 cm 2 , for the nonirradiated group. RESULTS: Using a single-factor analysis of variance, the 2 groups did not differ statistically. The overall major flap complication rate for both irradiated and nonirradiated groups was approximately 10%. CONCLUSION: Microvascular reconstruction was accomplished in both irradiated and nonirradiated head and neck patients, with a 99% total flap survival rate and a 10% major flap complication rate.

Abstract
Targeted muscle reinnervation (TMR) offers the potential for improved prosthetic function by reclaiming the neural control information that is lost as a result of upper extremity amputation. In addition to the prosthetic control benefits, TMR is a potential treatment for postamputation neuroma pain. Here, we present our surgical technique for TMR nerve transfers in transhumeral and shoulder disarticulation patients.

Abstract
Background The failure of sutures to maintain tissue in apposition is well characterized in hernia repairs. A mesh suture designed to facilitate tissue integration into and around the filaments may improve tissue hold and decrease suture pull‐through. Methods In vitro, the sutures were compared for resistance to pull‐through in ballistics gel. In vivo, closure of midline laparotomy incisions was done with both sutures in 11 female pigs. Tissue segments were subsequently subjected to mechanical and histological testing. Results The mesh suture had tensile characteristics nearly identical to those of 0‐polypropylene suture. Mesh suture demonstrated greater resistance to pull‐through than standard suture (mean(s.d.) 4·27(0·42) versus 2·23(0·48) N; P < 0·001) in vitro. In pigs, the ultimate tensile strength for repaired linea alba at 8 days was higher with mesh suture (320(57) versus 160(56) N; P < 0·001), as was the work to failure (24·6(14·2) versus 7·3(3·7) J; P < 0·001) and elasticity (128(9) versus 72(7) N/cm; P < 0·001) in comparison with 0‐polypropylene suture. Histological examination at 8 and 90 days showed complete tissue integration of the mesh suture. Conclusion The novel mesh suture structure increased the strength of early wound healing in an experimental model.
Surgical relevance Traditional sutures have the significant drawback of cutting and pulling through tissues in high‐tension closures. A new mesh suture design with a flexible macroporous outer wall and a hollow core allows the tissues to grow into the suture, improving early wound strength and decreasing suture pull‐through. This technology may dramatically increase the reliability of high‐tension closures, thereby preventing incisional hernia after laparotomy. As suture pull‐through is a problem relevant to all surgical disciplines, numerous additional indications are envisioned with mesh suture formulations of different physical properties and materials.

Abstract
The common peroneal nerve arises from the sciatic nerve and is subject to a variety of abnormalities. Although diagnosis is often is based on the clinical findings and electrodiagnostic tests, high-resolution sonography has an increasing role in determining the type and location of common peroneal nerve abnormalities and other peripheral nerve disorders. This article reviews the normal sonographic appearance of the common peroneal nerve and the findings in 21 patients with foot drop related to common peroneal neuropathy.

Abstract
Targeted muscle reinnervation (TMR) is a surgical procedure used to improve the control of upper limb prostheses. Residual nerves from the amputated limb are transferred to reinnervate new muscle targets that have otherwise lost their function. These reinnervated muscles then serve as biological amplifiers of the amputated nerve motor signals, allowing for more intuitive control of advanced prosthetic arms. Here the authors provide a review of surgical techniques for TMR in patients with either transhumeral or shoulder disarticulation amputations. They also discuss how TMR may act synergistically with recent advances in prosthetic arm technologies to improve prosthesis controllability. Discussion of TMR and prosthesis control is presented in the context of a 41-year-old man with a left-side shoulder disarticulation and a right-side transhumeral amputation. This patient underwent bilateral TMR surgery and was fit with advanced pattern-recognition myoelectric prostheses.

Simultaneous prosthetic mesh abdominal wall reconstruction with abdominoplasty for ventral hernia and severe rectus diastasis repairs. Plast Reconstr Surg 2015; 135:268-276. [PMID: 25539311 PMCID: PMC4280273 DOI: 10.1097/prs.0000000000000840] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2014] [Accepted: 06/03/2014] [Indexed: 11/27/2022]
Abstract
BACKGROUND Standard abdominoplasty rectus plication techniques may not suffice for severe cases of rectus diastasis. In the authors' experience, prosthetic mesh facilitates the repair of severe rectus diastasis with or without concomitant ventral hernias. METHODS A retrospective review of all abdominal wall surgery patients treated in the past 8 years by the senior author (G.A.D.) was performed. Patients with abdominoplasty and either rectus diastasis repair with mesh or a combined ventral hernia repair were analyzed. RESULTS Thirty-two patients, 29 women and three men, underwent mesh-reinforced midline repair with horizontal or vertical abdominoplasty. Patient characteristics included the following: mean age, 53 years; mean body mass index, 26 kg/m; average width of diastasis or hernia, 6.7 cm; and average surgery time, 151 minutes. There were no surgical-site infections and two surgical-site occurrences-two seromas treated with drainage in the office. After an average of 471 days' follow-up, none of the patients had recurrence of a bulge or a hernia. CONCLUSIONS For patients with significant rectus diastasis, with or without concomitant hernias, the described mesh repair is both safe and durable. Although this operation requires additional dissection and placement of prosthetic mesh in the retrorectus plane, it may be safely combined with standard horizontal or vertical abdominoplasty skin excision techniques to provide an aesthetically pleasing overall result.

Abstract
BACKGROUND Postamputation neuroma pain can prevent comfortable prosthesis wear in patients with limb amputations, and currently available treatments are not consistently effective. Targeted muscle reinnervation (TMR) is a decade-old technique that employs a series of novel nerve transfers to permit intuitive control of upper-limb prostheses. Clinical experience suggests that it may also serve as an effective therapy for postamputation neuroma pain; however, this has not been explicitly studied. QUESTIONS/PURPOSES We evaluated the effect of TMR on residual limb neuroma pain in upper-extremity amputees. METHODS We conducted a retrospective medical record review of all 28 patients treated with TMR from 2002 to 2012 at Northwestern Memorial Hospital/Rehabilitation Institute of Chicago (Chicago, IL, USA) and San Antonio Military Medical Center (San Antonio, TX, USA). Twenty-six of 28 patients had sufficient (> 6 months) followup for study inclusion. The amputation levels were shoulder disarticulation (10 patients) and transhumeral (16 patients). All patients underwent TMR for the primary purpose of improved myoelectric control. Of the 26 patients included in the study, 15 patients had evidence of postamputation neuroma pain before undergoing TMR. RESULTS Of the 15 patients presenting with neuroma pain before TMR, 14 experienced complete resolution of pain in the transferred nerves, and the remaining patient's pain improved (though did not resolve). None of the patients who presented without evidence of postamputation neuroma pain developed neuroma pain after the TMR procedure. All 26 patients were fitted with a prosthesis, and 23 of the 26 patients were able to operate a TMR-controlled prosthesis. CONCLUSIONS None of the 26 patients who underwent TMR demonstrated evidence of new neuroma pain after the procedure, and all but one of the 15 patients who presented with preoperative neuroma pain experienced complete relief of pain in the distribution of the transferred nerves. TMR offers a novel and potentially more effective therapy for the management of neuroma pain after limb amputation.

Abstract
Targeted muscle reinnervation (TMR) was initially designed to provide cortical control of upper limb prostheses through a series of novel nerve transfers. Early experience has suggested that TMR may also inhibit symptomatic neuroma formation. We present the first report of TMR performed at the time of a traumatic shoulder disarticulation. The procedure was done to prevent painful neuroma pain and allow for myoelecteric prosthetic use in the future. Eight months post-operatively, the patient demonstrates multiple successful nerve transfers and exhibits no evidence of neuroma pain on clinical exam. Using the Patient Reported Outcomes Measurement Information System (PROMIS), the patient demonstrates minimal pain interference or pain behavior. Targeted muscle reinnervation may be considered in the acute trauma setting to prevent neuroma pain and to prepare patients for myoelectric prostheses in the future.

Abstract
BACKGROUND Management of the open abdomen with polyglactin 910 mesh followed by split-thickness skin grafts allows safe, early closure of abdominal wounds. This technique can be modified to manage enteroatmospheric fistulae. Staged ventral hernia is performed in a less inflamed surgical field. METHODS A retrospective review was performed of 59 consecutive patients who underwent abdominal skin grafting for open abdominal wounds from 2001 to 2011. RESULTS The median length of follow-up was 215 days. Thirty-one percent of patients presented with preexisting enteroatmospheric fistulae, and 41% required polyglactin 910 mesh placement before skin grafting. Partial or complete skin graft failure occurred in 7 patients. Four patients required repeat skin grafting. All patients ultimately achieved abdominal wound closure, and none developed de novo fistulae. CONCLUSIONS With proper technique, skin grafting of the open abdomen with a planned ventral hernia repair is a safe and effective alternative to delayed primary closure.

Abstract
BACKGROUND While studies have compared aesthetic outcomes following wide local excision of head and neck melanoma, none have evaluated this important outcome from the patient's perspective. Indeed, one could argue that the psychosocial impact of head and neck melanoma excision and reconstruction is more accurately assessed by deriving patient-based as opposed to surgeon-based outcome measures. OBJECTIVE To evaluate aesthetic outcomes following wide local excision of head and neck melanoma from the patient's perspective. METHODS Fifty-one patients who underwent excision of 57 head and neck melanomas followed by immediate closure by primary repair, skin grafting, local flap coverage or free tissue transfer were asked to complete a written survey at least six months after their surgery. A visual analogue scale (VAS) was used to assess the patient's perception of appearance alteration, satisfaction with his or her appearance, and emotional impairment. An ordinal scale was used to evaluate several criteria of the reconstructive outcome (pain, itching, colour, scarring, stiffness, thickness and irregularity). RESULTS Forty-two patients (82.4%) completed the survey. There were significant correlations between VAS scores reported for appearance alteration, satisfaction with outcome and emotional impairment (P=0.001). Patients who received skin grafts reported significantly unfavourable VAS scores compared with other methods of reconstruction (P=0.046). Moreover, skin grafts received significantly worse ordinal scale ratings for itching (P=0.043), colour (P=0.047), scarring (P=0.003) and stiffness (P=0.041) compared with other methods of reconstruction. Both skin grafts and free flaps were reported to have significantly less favourable thickness (P=0.012) and irregularity (P=0.036) than primary closure or local tissue transfer. There was no significant difference between patients undergoing primary closure with local tissue transfer (P>0.413). Other factors related to the patient's VAS scores included location of the melanoma (P=0.033), size of defect (P=0.037) and recurrence of melanoma (P=0.042). CONCLUSION The degree of emotional impairment following reconstruction of head and neck melanoma excision defects was correlated with the patient's perception of appearance alteration. From the patient's perspective, primary closure and local tissue transfer appeared to result in the highest aesthetic satisfaction.

Abstract
BACKGROUND The Ventral Hernia Working Group (VHWG) recently proposed a grading system to assist surgeons in selecting the appropriate mesh based on an individual patient's risk of developing a postoperative complication. The VHWG grading scale was used to evaluate the incidence of surgical-site complications in 100 consecutive midline ventral hernias repaired with uncoated mid-weight polypropylene mesh. METHODS A retrospective review was conducted of 100 consecutive cases of midline ventral hernia repair using an intra-abdominal mesh underlay between July 2005 and May 2010. The median duration of follow-up was 23 months. RESULTS Using the VHWG scale, 50 percent of cases were considered grade 2 ("Co-morbid") and 28 percent considered Grade 3 ("Potentially Contaminated"). The remaining cases were Grade 1 ("Low-risk"). Overall, there was a 5.6 percent rate of hernia recurrence, with a mean time to recurrence of 17 months. There were no enterocutaneous fistulae or infections requiring mesh removal. CONCLUSION The use of uncoated mid-weight polypropylene mesh for reinforcement of midline ventral hernia repairs was not associated with increased rates of infection, fistula formation, or clinically significant adhesions. These findings challenge the recommendation by the VHWG to avoid synthetic repair material in patients with comorbidities or in "potentially contaminated" fields.

Abstract
PURPOSE As reconstructive transplantation emerges as an increasingly viable option for upper limb amputees, a better understanding of quality of life (QOL) outcomes is needed to evaluate the benefits and risks of the procedure from the patient perspective. METHODS To address this need, we searched PubMed (1998-2011) to characterize QOL outcomes among upper limb transplant recipients. We identified 27 articles reporting on QOL outcomes in hand transplantation. Common instruments to assess domains of QOL in hand transplantation include the Disabilities of the Arm, Shoulder, and Hand questionnaire, the Medical Outcomes Study Short Form-36, and the International Registry on Hand and Composite Tissue Transplantation's Hand Transplantation Score System. RESULTS Preliminary reports using standardized measures indicate that most hand transplant recipients described improved QOL. Several studies also qualitatively reported that recipients expressed satisfaction with cosmetic, sensory, functional, and social outcomes after transplantation. However, our review suggests that the measurement of QOL in hand transplantation is limited, although it is largely driven by QOL considerations. CONCLUSIONS This review highlights the need for improved measurement of QOL in hand transplantation. The preliminary QOL findings across published hand transplantation articles will aid in improving the future assessment of QOL in hand transplantation.
