The Modified Lepird Procedure for Correction of Metatarsus Adductus.

Metatarsus adductus is a common transverse plane congenital foot deformity. Achieving anatomic correction can be challenging, as all osteotomy procedures have a steep learning curve. A multitude of complications can occur when using traditional pan-metatarsal osteotomy approaches. The modified Lepird procedure is performed with proximal base osteotomies on all 5 metatarsals oriented dorsal distal to plantar proximal. All screws are inserted parallel to each other, allowing the forefoot to move laterally as a unit. The foot and ankle surgeon is able to dial in with precision the exact amount of forefoot abduction necessary to correct the deformity. The modified Lepird procedure dynamically corrects the metatarsus adductus deformity so it can easily prevent any over- or undercorrection that may occur intraoperatively. The author recommends this procedure when pan-metatarsal base osteotomies are required for correction of metatarsus adductus and associated deformities.
