Hallus Varus

usually iatrogenic hallux varus, often associated with a bunionectomy that included a fibular sesamoidectomy. 

RX: tenodesis-type transfer of the extensor hallucis brevis is the procedure of choice.  The tendon is cut at its musculotendinous junction and transferred beneath the transverse metatarsal ligament proximally into the lateral aspect of the first metatarsal.  A medial release of the abductor hallucis and medial capsule may also be necessary.  The transfer is a static tenodesis and does not function dynamically.  An arthodesis should be reserved for a degenerative joint.
