A new device for performing triplanar distal osteotomy for hallux valgus.

Triplanar distal osteotomy is a safe procedure for mild-to-moderate hallux valgus deformity. It allows shortening and plantar displacement of the first metatarsal while correcting the intermetatarsal angle. However, complications such as dorsiflexion and excessive shortening of the first metatarsal have been associated with distal osteotomy. We describe a new device, designed by one of the authors (P.R.), that enables precise positioning of the Kirschner guide wire for the osteotomy cuts.
