We present a case of disruption of the posterolateral corner of the knee with avulsion of the tendon of biceps femoris. Repair and reconstruction included an allogenic tendon graft to replace the posterior cruciate ligament. Surgery was followed by a complete common peroneal nerve palsy. Revision surgery revealed that the nerve had been displaced anteriorly by avulsion of the biceps tendon and ...
INTRODUCTION This project aims to study the regeneration of non-repairable lesions of peripheral nerve by muscle grafts enhanced with growth factors. MATERIAL AND METHODS The experiment was carried out in two phases. The first one compared direct suture of a critical defect in the sciatic nerve of ten rats, with the interposition of autologous muscle graft, denatured by heat, in another ten. ...
Abstract Objective: the present study was performed to evaluate Mineralized Plasmatic Matrix (MPM) as a grafting material around immediate dental implant in mandibular posterior teeth Material and Methods: eight patients were selected for use MPM implant. After surgery each patient evaluated clinically at following interval immediate, one week, two weeks, three months postoperatively for:: Pres...
Facial nerve palsy may represent an important complication of head trauma; yet, an adequate surgical treatment can reduce negative effects of such injuries. The surgical treatment usually consists of nerve decompression, nerve anastomosis and graft technique with n. auricularis magnus. In this study a retrospective analysis of the patients treated from the traumatic facial palsy in a ten-year p...
PURPOSE As alternatives to autograft become more conventional, clinical outcomes data on their effectiveness in restoring meaningful function is essential. In this study we report on the outcomes from a multicenter study on processed nerve allografts (Avance® Nerve Graft, AxoGen, Inc). PATIENTS AND METHODS Twelve sites with 25 surgeons contributed data from 132 individual nerve injuries. Data...
RESULTS: Axon counts clearly demonstrated disproportionately reduced regeneration in the longer graft compared to the short graft when measuring at equivalent distances to the spinal cord: the number of regenerated axons in the long graft was 57% of those regenerated in the short graft. Additionally, retrograde labeling showed significantly fewer motoneurons were found to be regenerating axons ...
In this era of tissue bioengineering an autogenous nerve graft may be considered the ultimate biocompatible, resorbable nerve conduit, with a basil lamina, preformed guidance channels, a reserve of viable Schwann cells, and nerve growth factors. In addition, it is capable of developing an intrinsic circulation. The nerve graft provides a regenerating axon with a means for passage to the distal ...

ObjectiveComprehensive functional, histomorphometrical and immunohistochemical assessment of sciatic nerve regeneration through an inside-out vein graft in rat. DesignExperimental in vivo study. AnimalsFiftyfour healthy male White Albino rats. ProceduresThe rats were divided into three experimental groups (n=18), randomly: Sham-operation (NC), Transected control (TC) and Inside-out vein graft (...
