We study the influence of blood flow on the neuroma formation after transposition of the nerve stump into a vein. A total of 30 rats were divided into two groups. In group (I), a 10-mm segment of the femoral vein was excluded from the blood stream. A venotomy was performed in the middle of this segment. The proximal nerve stump of femoral nerve was transposed into the lumen of the femoral vein via a venotomy and held with an epineural suture through the venous wall. In group (II), the same technique was used as in group (I) but without exclusion of the vein segment from blood flow...

BACKGROUND: Low anterior resection for rectal cancer often results in severe bowel dysfunction, specifically low anterior resection syndrome (LARS), with symptoms such as incontinence, urgency, and frequent bowel movements. Percutaneous tibial nerve stimulation (PTNS) resulted in a high rate of success in patients with fecal incontinence. The aim of this study was to evaluate the effectiveness of treatment with PTNS in LARS and to identify predictors of the outcome of the technique. METHODS: The study was conducted from May 2012 to April 2015 at the Alvaro Cunqueiro Hospital, University Hospital Complex of Vigo, Spain...

BACKGROUND: Regenerative Peripheral Nerve Interfaces (RPNIs) are neurotized muscle grafts intended to produce electromyographic signals suitable for motorized prosthesis control. Two RPNIs producing independent agonist/antagonist signals are required for each control axis; however, it is unknown whether signals from adjacent RPNIs are independent. The purpose of this work was to determine signaling characteristics from two adjacent RPNIs, the first neurotized by a foot dorsi-flexor nerve and the second neurotized by a foot plantar-flexor nerve in a rodent model...

Autografts represent the gold standard for peripheral nerve reconstruction but their limited availability, the discrepancy of nerve caliber and long surgical times are drawbacks. Allografts have therefore become a valid alternative option. In particular, acellular nerve allografts (ANAs) rather than fresh allografts do not need immunosuppression and appear to be safe and effective based on recent studies. An innovative method was conceived to obtain ANAs, so as to speed up nerve decellularization, without compromising nerve architecture, and without breaking the asepsis chain...

PURPOSE: Sacral nerve and tibial nerve stimulation have been singly used to treat overactive bladder (OAB). This study evaluated the effects of both combined stimulation on treating bladder overactivity in pigs and explored a novel treatment modality for OAB. METHODS: An implant-driven stimulator of the S3 spinal nerve was implanted in 5 pigs. The contralateral tibial nerve was stimulated by an external stimulator. Multiple cystometrograms were performed to determine the effects of single nerve stimulation and combination sacral nerve stimulation (SNS) and tibial nerve stimulation (TNS) on the micturition reflex by infusing normal saline (NS) or acetic acid (AA)...

The aim of the present study was to analyze the mechanism by which nerve growth factor (NGF) promotes callus formation in mice with tibial fracture. NGF transgenic homozygotic mice and NGF wild homozygotic mice were selected to construct non-stabilized fracture model of tibia. The mice were sacrificed on days 7, 14 and 21, respectively, and each group had a sample with 8 mice at each point in time. X-ray radiography and safranin fast green were used to observe fracture healing and in situ hybridization was used to examine the NGF mRNA expression of tibia at each phase of fracture healing...

The authors present a case of angioleiomyoma situated in the posterior knee. A 47-year-old Caucasian woman presented in 2011 with recurrent stabbing pain on the lateral aspect of her right knee. She reported having pain for the last 6years. She had no history of trauma. In 2008 she was treated with a diagnostic arthroscopy and transposition of the tibial tuberosity, with no benefit to her symptoms. Electromyography of the lower limbs showed asymmetry of the amplitude of sensitive action potential of the superficial fibular nerve...

The goal of this study was to describe an internal fixation technique for periprosthetic humeral fractures using a cortical onlay strut allograft stabilized with cerclage wires and to evaluate the preliminary results of this approach. An anterolateral approach was used to direct access the fracture and to protect the radial nerve. The fracture was reduced with two forceps, under visual control. The fracture was surrounded by two hemicylinder tibial allografts, placed around the humerus with no prior reaming to create a "sarcophagus" system...

PURPOSE: Percutaneous tibial nerve stimulation (pTNS) was originally developed to treat urinary incontinence. Recently, some case series have also documented its success in the treatment of fecal incontinence. Nevertheless, the mechanism underlying this effect remains unknown but may be related to changes in rectal capacity. The aim of this study was to investigate the success of pTNS for the treatment of fecal urge incontinence and assess the influence of rectal capacity on treatment efficacy...

Malignant peripheral nerve sheath tumor (MPNST) is a rare form of sarcoma arising from Schwann cells or pluripotent cells of the neural crest. Malignant triton tumor (MTT) is a subtype of MPNST with a component of malignant rhabdomyoblasts in addition to malignant Schwann cells. MPNST and MTT are both aggressive malignancies that most commonly arise from large deep neurofibromas in patients with neurofibromatosis type 1 (NF-1). However, sporadic non-NF-1 cases of MTT have also been reported in the literature...

AIM: Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive procedure, which has been demonstrated to be effective in faecal/urinary incontinence, but has never been tested in Low Anterior Resection Syndrome (LARS). The severity of LARS may be evaluated by the LARS-score, but rectal cancer treatments may also affect urinary and sexual function, which are not explored by the LARS-score. The TAPE-score is a new validated index addressing the overall pelvic-floor functions...

BACKGROUND: Isolated gastrocnemius contracture (IGC) is associated with various foot and ankle pathologies. To address the problem of IGC, a number of gastrocnemius lengthening procedures have been described. Although proximal medial gastrocnemius recession (PMGR) has shown to be an effective operative treatment for IGC, it poses risks to various anatomic structures around the knee joint and requires the patient to be positioned prone. As an alternative, we proposed to release the medial gastrocnemius at the division between the proximal one-third and distal two-thirds of the gastrocnemius muscle to correct equinus contracture, while minimizing risk to other structures...

OBJECTIVES/HYPOTHESIS: Cranial nerve transection during head and neck surgery is conventionally repaired with microsuture. Previous studies have demonstrated recovery with laser nerve welding (LNW), a novel alternative to microsuture. LNW has been reported to have poorer tensile strength, however. Laser-activated chitosan, an adhesive biopolymer, may promote nerve recovery while enhancing the tensile strength of the repair. Using a rat posterior tibial nerve injury model, we compared four different methods of nerve repair in this pilot study...
