Split biceps femoris tendon reconstruction for proximal tibiofibular jointinstability

Recurrent instability of the proximal tibiofibular joint is an infrequently diagnosed abnormality. We present a new technique for reconstructing the j oint using a split biceps femoris tendon passed through a bone tunnel in bo th the proximal tibial metaphysis and fibular head. The case report is also presented. The procedure offers an anatomic reconstruction and firm stabil ization. It allows normal motion of the proximal tibiofibular joint and pre serves the normal mechanics of the ankle. This procedure is an excellent al ternative to resection of the fibular head, transarticular arthrodesis, or pseudoarthrosis focus at the fibular head.
