Use of superficial peroneal nerve graft for treating peripheral nerve injuries

Abstract

ObjectiveTo evaluate the clinical results from treating chronic peripheral nerve injuries using the superficial peroneal nerve as a graft donor source.MethodsThis was a study on eleven patients with peripheral nerve injuries in the upper limbs that were treated with grafts from the sensitive branch of the superficial peroneal nerve. The mean time interval between the dates of the injury and surgery was 93 days. The ulnar nerve was injured in eight cases and the median nerve in six. There were three cases of injury to both nerves. In the surgery, a longitudinal incision was made on the anterolateral face of the ankle, thus viewing the superficial peroneal nerve, which was located anteriorly to the extensor digitorum longus muscle. Proximally, the deep fascia between the extensor digitorum longus and the peroneal longus muscles was dissected. Next, the motor branch of the short peroneal muscle (one of the branches of the superficial peroneal nerve) was identified. The proximal limit of the sensitive branch was found at this point.ResultsThe average space between the nerve stumps was 3.8 cm. The average length of the grafts was 16.44 cm. The number of segments used was two to four cables. In evaluating the recovery of sensitivity, 27.2% evolved to S2+, 54.5% to S3 and 18.1% to S3+. Regarding motor recovery, 72.7% presented grade 4 and 27.2% grade 3. There was no motor deficit in the donor area. A sensitive deficit in the lateral dorsal region of the ankle and the dorsal region of the foot was observed. None of the patients presented complaints in relation to walking.ConclusionsUse of the superficial peroneal nerve as a graft source for treating peripheral nerve injuries is safe and provides good clinical results similar to those from other nerve graft sources.

Crioterapia Em Modelo De Compressão Do Nervo Isquiático: Análise Funcional E Morfológica

“…2 Dependendo do tipo da lesão, pode haver recuperação espontânea ou ser necessário uma intervenção cirúrgica ou terapêutica para minimizar os danos causados pela lesão. [3][4][5] Em relação ao tratamento, existem diversas técnicas que podem ser utilizadas dentro da fisioterapia, como a crioterapia, um tipo de termoterapia em que se aplica o frio como agente terapêutico. 6 A crioterapia induz a redução da temperatura corporal, que diminui a taxa metabólica dos tecidos, as reações enzimáticas, a liberação de histamina, leva à vasoconstrição com consequente diminuição do fluxo sanguíneo, permeabilidade da membrana e edema.…”
