The triplane Austin bunionectomy: a review and retrospective analysis

The purpose of this manuscript is to introduce an alternative method of performing triplane Austin bunionectomies using a 0.062-inch Kirschner wire for fixation. This procedure was employed in clinical situations where there was an elevated first ray and/or a submetatarsal two lesion intractable plantar keratoma. X-ray criteria include a mild to moderate increase in the intermetatarsal angle (IMA) and a proximal articular set angle (PASA) deformity. Elevatus of the first ray is evident. Thirty-six cases were reviewed over a 5-year period. Follow-up ranged from 6 months to 3 years. Statistical results support the use of this capital osteotomy for the reduction of intermetatarsal angle and proximal articular set angle, and to plantarflex the first ray. Early mobilization with return of function of first metatarsophalangeal joint (MPJ) range of motion makes this an ideal procedure for the podiatric surgical patient who needs to return to activity as soon as possible.
