PurposeWe want to evaluate the feasibility of transferring a motor branch of the the anterior tibial muscle (ATM) on the extensor digitorum longus (EDL) in order to evaluate this procedure in patients with spastic Equino Varus Foot (EVF) following a post-stroke hemiplegia.MethodsTen cadaveric dissections from five fresh frozen human cadavers were performed in order to establish the anatomic feasibility of transferring a motor branch of the deep peroneal nerve with is usually destinated to the Anterior Tibialis Muscle (ATM) onto the branch of the Extensor Digitorum Longus (EDL), to manage spastic equinovarus foot (SEF). Results Six cases (60%) presented 3 branches detonated to the ATM, one case (10%) presented 5 branches, 3 cases (30%) had 4 branches. In all specimens, the coaptation between the motor branch to the anterior tibial muscle, referred as the ‘effector’ branch, and the branch of the EDL ‘receiver’ branch was feasible without tension and did not require any intra-neural dissection.ConclusionThis anatomical study confirms the feasibility of transferring a motor branch from the ATM to the EDL to correct a spastic EVF.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
