Abstract

BACKGROUND: The Ludloff first metatarsal osteotomy is used to correct the increased 1-2 intermetatarsal angle associated with hallux valgus deformity. We studied the spatial geometry of this osteotomy to determine the ideal parameters of the osteotomy saw cut and its rotation to give an optimal correction. METHODS: Three-dimensional computer modeling software was used to perform a virtual Ludloff osteotomy of the first metatarsal. Different geometric parameters of the osteotomy were studied. The osteotomy was rotated in virtual space and the geometric changes occurring in the virtual bone were then measured by the software. RESULTS: The optimal Ludloff osteotomy started at the dorsum of the ..
