HAV
- Surgical Correction
Surgical
correction of HAV is quite common and there are numerous methods used.
Hallux abducto valgus surgery can be broken down into two types of
surgical procedures, those that preserve or reconstruct the joint
and those that remove or remodel the joint.
Case
1: Austin (Chevron) "V" osteotomy which
realigns the joint with a lateral shift of the metatarsal
head via a distal osteotomy. K-wire fixation is shown.
Note the position of the sesamoids.

Case
2: Keller arthroplasty, with resection of the base
of the proximal phalanx. This can lead to ongoing instability
even with soft tissue reconstruction of the joint (as
this case shows).

Post
HAV surgery (psuedo joint)
Lateral
Oblique View- Distal metatarsal osteotomy with proximal hemiphalagectomy.
The joint space is maintained with two Oblique K-wires allowing
the formation of a psuedo joint.
