Correção do “pé caído” por paralisia do nervo fibular, pela transferência do tendão tibial posterior para o dorso do pé via membrana interóssea

Resumo

Objective: To evaluate the clinical and functional results of the treatment of drop foot due to lesions of common peroneal nerve, by posterior tibial tendon transfer through the interosseous membrane to the dorsal side of the foot. Methods: We retrospectively evaluated twelve patients with traumatic injury of the common peroneal nerve, analyzing, preoperatively, the level of injury, type of trauma, use of orthoses, time of injury and the presence of equine non-reducible passively. The patients underwent surgical treatment of foot drop by this technique from March 2007 to April 2011. The mean age was 38.16 years and mean follow-up of 20.9 months. The postoperative evaluation was done by a questionnaire created by the authors. Results: Nine of the twelve patients used orthoses previously. After the transfer of the posterior tibial tendon, only two patients remained using orthoses. Six patients returned to recreational activities and only one had severe limitation. Seven patients showed no abnormalities in gait. Nine patients present feet in neutral position at the end of the study. Conclusion: The transference of the posterior tibial tendon to the dorsal side of the foot thought the interosseous membrane led to satisfactory result with improvement of gait and foot position not requiring the use of orthoses in most patients.
