BACKGROUND: Distal nerve transfer has proven efficacy. The purpose of this study was to investigate if an injured nerve can be used as a donor nerve for transfer, and to determine the threshold of injury. MATERIALS AND METHODS: Rat's left ulnar-nerves in the axilla with different degrees of injury were selected as the donor nerves for transfer, and the musculocutaneous-nerves the target nerves for being re-innervated. Six rats each served as positive and negative controls: Group A, intact ulnar-nerve transfer; and Group E, the ulnar-nerve was cut but no transfer...

PURPOSE: This study aimed to determine the thicknesses of the three locations used as donor sites for radial forearm (RF), anterolateral thigh (ALT), and peroneal flaps and to determine probable contributing factors of the thickness. METHODS: This study included 201 healthy participants (mean age: 45.8 ± 17.2 years; male: 114; female: 87; BMI: 24.3 ± 4.3). Sonography was used to measure the thickness of flap donor sites. Forward stepwise regressions were conducted to determine the contributing factors of flap thickness...

BACKGROUND: The aim of our study was to objectively test sensibility on the dorsal side of the hand in patients with radial nerve injury, to document deficits and to detect if surgery for sensory reconstruction is needed. METHODS: Nineteen patients of mean age 31 ± 10 years were examined at a mean of 26.4 ± 27.8 months post radial nerve injury. Sensory mechanical thresholds on the dorsal surface of the hand were evaluated using Semmes-Weinstein monofilaments...

Rotationplasty is a limb-sparing surgical option in lower limb malignancies. Sciatic or tibial nerve encasement has been considered an absolute contraindication to this procedure. We report a case of an 18-month-old girl with a rhabdomyosarcoma that affected the leg and popliteal fossa, with neurovascular involvement. Knee and proximal leg intercalary resection was performed followed by reconstruction with free microvascular rotationplasty and neurorraphy from tibial division of sciatic nerve to sural and tibial nerves, and from saphenous nerve to superficial peroneal nerve...

INTRODUCTION: Today, reconstructive surgeons offer an array of options to reconstruct the lip defects. Herein we present our experience of using free double-paddle peroneal flaps for extensive lip defect reconstruction. PATIENTS AND METHODS: From 1996 to 2014, 16 patients with extensive lip defects after tumor ablation were included. Free double-paddle peroneal flaps were used for reconstructions. In terms of flap design, one skin paddle superiorly placed on the lateral lower leg was used to reconstruct intraoral defects, whereas the other was inferiorly located and was used to reconstruct extraoral defects...

BACKGROUND: Large soft tissue defects of the abdominal wall resulting from various reasons may require free tissue transfer. METHODS: A literature search of PubMed and Cochrane electronic databases was conducted to identify articles involving abdominal wall reconstruction (AWR) with microsurgical flap. Number of cases, etiology, and reconstruction site, type of microsurgical flap and recipient vessels were analyzed. RESULTS: Thirty-eight articles published between 1983 and 2016 reported on 149 patients undergoing free flap AWR...

BACKGROUND: Overgrowth of the stump skeleton is a major complication seen in children after an amputation. In advanced cases, perforation of the bone spike through the skin can occur. Many surgical treatments have been employed to treat and prevent this, with best results seen when non-vascularised osteo-chondral bone grafts are placed to try to mimic a trans-articular amputation. We reviewed our outcomes using vascularized bone flaps to prevent and treat spiking. PATIENTS AND METHODS: Between 2000 and 2016 we carried out six vascularised osteo-cartilaginous bone capping procedures...

BACKGROUND: The upper thigh has provided multiple new soft tissue free flaps in recent decades, including the anterolateral thigh, anteromedial thigh, transverse upper gracilis, the profunda artery perforator, and superficial circumflex iliac perforator flaps. The purpose of this study is to describe a new, reliable free flap option in the upper thigh: the proximal superficial femoral artery perforator (p-SFAP) flap. METHODS: A cadaveric dissection study was performed to confirm clinical landmarks and evaluate pedicle characteristics...

BACKGROUND: Complex lower extremity trauma still poses a formidable challenge for micro vascular reconstruction. The extensive surrounding zone of trauma can make it difficult to find a suitable recipient pedicle for anastomosis. A need was felt for exploration of newer recipient vessels in lower extremity which could be harnessed for reliable and tension free micro anastomosis. The purpose of the present report is to highlight the possibility of using medial sural artery for safe micro vascular anastomosis in selected scenarios like vessel depleted extremity...

The anterolateral thigh (ALT) flap is one of the most commonly used flap worldwide, as both free flap and pedicled local flap. Here, we report the use of a pedicled chimeric sensitive ALT and vastus lateralis muscle (VLM) flap in a patient with a 12 cm × 8 cm contaminated soft tissue defect of the right inguinal region with exposed femoral vessels. The flap was harvested based on two perforators, one musculocutaneous and one pure muscular, each nourished separately a sensitive fasciocutaneous component and a vastus lateralis muscle component, respectively...

BACKGROUND: Patients may require microvascular free tissue transfer (MFTT) following re-irradiation for recurrent cancer or radiation complications. The objective of this study was to describe the indications for and outcomes of free flaps performed in twice-radiated patients. METHODS: A retrospective chart review identified the indications for and outcomes of 36 free flaps performed on 29 twice-irradiated patients. RESULTS: The free flap success rate was 92%...

PURPOSE: Reconstruction of perineal defects remains a challenge because such defects can be extensive, complex, and three-dimensional. This report presents a retrospective review of our past 5 years of experience in perineal reconstruction, and suggests a simple algorithmic approach according to anatomical divisions with multiple pedicled perforator flaps for extensive perineal defects. METHODS: From January 2011 to December 2015, 16 patients, including 5 men and 11 women, underwent reconstruction of extensive perineal defects...

BACKGROUND: Clinical outcomes of consecutive use of the lateral calcaneal artery (LCA) as a recipient vessel for microsurgical reconstruction have not been reported. This study aimed to evaluate the feasibility and safety of the LCA as a recipient vessel for microsurgical foot reconstruction based on anatomical study of CT angiography and clinical results of using this vessel as the recipient. METHODS: Anatomic study was performed using CT angiography of 61 lower extremities (31 patients)...

Breast lymphedema (BLE) has been reported as a complication following breast cancer treatment. As for extremity lymphedema treatment, supermicrosurgical lymphaticovenous anastomosis (LVA) is considered an option for the treatment of progressive BLE refractory to conservative treatments, but no case has been reported so far. We report the first case of BLE successfully treated with supermicrosurgical LVA. A 55-year-old female presented with left BLE after breast conserving surgery and axillary lymph node dissection and adjuvant radiotherapy...

REVIEW
Ivica Ducic, Bauback Safa, Erick DeVinney
Peripheral nerve repair can be very rewarding for both surgeon and patient when expected outcomes are achieved. In many cases, however, the results are suboptimal due to number of possible objective and technical reasons. Although we cannot influence patent's comorbidities, the extent or mechanism of the nerve injury, we may help optimize technical details when aiming towards improved outcomes. While the suture coaptation for primary nerve repair or nerve reconstruction with grafting served as the reconstructive standard for many decades, technical imperfections remain threats to reconstructive goals...
