Fixation of split anterior tibialis tendon transfer by anchorage to the base of the 5th metatarsal bone.

Split anterior tibialis transfer is a procedure, frequently performed in combination with triceps surae lengthening, to treat equinovarus foot deformity in adult hemiplegia patients. The authors present their surgical technique, with tendon fixation by an anchor to the base of the fifth metatarsal. Although bone-tendon anchor fixation is widespread in orthopedic surgery, it is original in this type of indication. It is simpler, and less traumatic for the bone than a bone tunnel and less traumatic for the sole than transplantar fixation. The very distal attachment to the base of the 5th metatarsal bone solves the common problem of adjusting the tension of tendon transfer. The authors report their experience of 22 split transfers from 2005 to 2008.
