ABSTRACT
For metatarsalgia and lesser toe deformities, a commonly performed procedure is the Weil osteotomy, which inevitably depresses the metatarsal head, changing the intrinsic muscle axis and generating phalanx extension. The objective of this study is to present a new metatarsal osteotomy that shortens or lengthens and elevates the metatarsal head, the elevating metatarsal osteotomy (EMO), with its geometrical analysis and possible applications. A geometrical model was designed, planning an oblique subcapital osteotomy with slice resection and distal displacement. A trigonometric analysis was done to calculate how to shorten, elevate, or lengthen the metatarsal head. The EMO elevates the head in one-third of the width of the resected slice. Distal and dorsal displacement of the metatarsal head results in an elevation and lengthening of the metatarsal bone (60% elevation and 65% lengthening). Performing an elevating metatarsal osteotomy will lengthen and elevate the metatarsal head, which sometimes is necessary when treating toe deformities and instability.
