Introduction: Reconstructive options for peripheral nerve gaps are currently limited. Autogenous nerve grafts continue to be the gold standard, but are limited by the availability of graft material. All other methods of nerve grafting are either experimental or have limited clinical applicability. We propose developing a tissue engineered peripheral nerve allograft that is non-immunogenic but c...

UNLABELLED Autogenous bone graft is the ideal substrate for primary and revisional foot and ankle surgery. The distal medial tibia is an easily accessible site that provides both cancellous and corticocancellous autograft. Thirty cases of distal tibial bone graft with a minimum follow-up of 1 year are presented. There was an 86% union rate, and there were no stress fractures, persistent pain, o...

Objective- To evaluate greater omentum as an autogenous free graft in enhancing bone healing.Design- Prospective descriptive trial.Animals- Ten mongrel adult dogs, 3 to 4 years old and weighing 25.2 to 31 kg, assigned into two equal experimental and control groups (5dogs/group), were used.Procedures- Mid-shaft osteotomy on right radius was followed by a partial omentectomy in all dogs. A 30x30 ...

An orientated substratum has been implicated in the development and regeneration of axons and synapses. We prepared a basement membrane matrix from autogenous striated muscle, used it to repair the sciatic nerve in rats, then investigated the results by histology and electrophysiology. When treated grafts were coaxially aligned with the nerve fascicles functional recovery appeared within 30 day...

BACKGROUND Mature autogenous arteriovenous fistulas have better long term patency and require fewer secondary interventions compared to arteriovenous prosthetic graft. Our Study evaluated vascular patency rates and incidence of interventions in autogenous arteriovenous fistulas and grafts. MATERIAL AND METHODS A total of 166 vascular access operations were performed in 153 patients between De...

Recurrent compressive neuropathy of the median nerve due to cicatrix is an extremely challenging clinical problem. Available treatment techniques are difficult and results uncertain. Early experience with the autogenous vein graft wrapping technique has shown great promise for the treatment of chronic compressive neuropathy after other procedures have failed. We report on 3 patients with averag...

J Korean Assoc Oral Maxillofac Surg 2012;38:221-30) Objectives: This study sought to evaluate the efficacy of collagen graft materials, as compared to other graft materials, for use in healing calvarial defects in rabbits. Materials and Methods: Ten mm diameter calvarial defects were made in ten rabbits. The rabbits were then divided into 4 groups: control, autogenous bone graft, SureOss graft,...

PURPOSE To compare sciatic nerve regeneration in rats using three different techniques of repair. METHODS Fifteen isogonics rats were divided into three groups according to the method used to repair a 5-mm long defect created in the sciatic nerve: autogenous graft (Group A), polyglycolic acid tube (PGAt) (Group B), and of the association of PGAt with the graft (Group C). Histological analysis...

Implant therapy in the atrophic posterior maxilla becomes challenging in the presence of reduced maxillary bone height. Sinus augmentation can be performed for resolving this condition prior to implant placement. The aim of this article was therefore to evaluate implant survival rates in the grafted sinus taking into account the influence of the implant surface, graft material, and implant plac...

PURPOSE To evaluate the applicability of the use of autogenous muscle treated in various ways, as a substitute of the nerve grafts. METHODS Rats were divided into seven groups that received, as a treatment for a standard nerve injury, the following types of grafts: fresh muscle, muscle fixed with 10% formaldehyde, muscle frozen in a freezer, muscle frozen in refrigerator, nerveless muscle, pe...
