Lesser metatarsal osteotomies. A biomechanical approach to metatarsalgia.

Abstract

As with most other orthopedic conditions, a firm understanding of the normal and pathologic biomechanics of the lesser metatarsals is essential when contemplating treatment of metatarsalgia. Despite its prevalence, metatarsalgia remains a technically demanding surgical challenge. Some of the difficulty with treatment of this problem arises because of some of the controversies discussed previously. Many lesser metatarsal osteotomies have been described, and their success depends on many factors. Alleviating the correct amount of pressure underneath the metatarsal head without adversely affecting the biomechanics of the region demands an exacting osteotomy that is stable and readily heals. Much of the research done to date has not proved which procedure can achieve these goals reproducibly for patients. It is hoped that future investigations will guide treatment choices and allow patients to obtain relief from this difficult problem with greater success.
