[Lesser toe deformities].

Abstract

Lesser toe deformities often lead to painful calluses and metatarsalgia. Depending on the different underlying etiologies it is mandatory to perform a meticulous clinical assessment including the whole foot and the entire lower limb. Prior to any surgical interventions it is necessary to evaluate the deformity at all three joint levels. The metatarsophalangeal joint acts as a key joint. Any dorsal subluxation or dislocation has to be addressed first. This may include various soft tissue procedures and shortening osteotomies of the metatarsals. After successful realignment contractures of the distal joints have to be corrected. Since function of the lesser toes mainly depends on stability of the distal joints arthrodeses of the proximal and distal interphalangeal joints are superior to any resection arthroplasties.
