Tibialis posterior transfer (for foot drop)

Historically the Tibialis posterior transfer for foot drop has been the main intervention for patients intolerant of , or requiring better function than is afforded by , a simple stabilising Ankle Foot Orthosis (AFO).
Significant improvements in non-operative management options , both with energy returning Carbon fibre foot drop splints and FES (functional electrical stimulation) have made this a far less commonly performed operation for an isolated and flexible foot drop deformity.
In patients with other co-existing pathologies which can accompany the foot drop (such as Achilles contracture or a varus heel) which make conservative management less effective , there remains a strong indication for the operation.
