Retrofibular transfer of tibialis posterior to control residual adduction deformity of clubfoot.

The tibialis posterior muscle was transferred behind the fibula through the peroneal muscles and anchored in the fourth intermetatarsal cleft as an adjuvant step in postero-medial release to control the adduction deformity of the forefoot in clubfeet. The results of this procedure were compared after five years with conventional methods, including postero-medial release alone, in ten identical bilateral clubfeet. The immediate and late correction of the adductus deformity were significantly improved by this additional operation.
