Splay Toe after Freiberg-Köhler's Osteonecrosis: A Case Report of a Successful Operative Treatment in a Rare Multiplanar Foot Deformity.

Abstract

"Splay toe" is a rare deformity of the forefoot and often causes the occurrence of metatarsalgia and dysfunction while walking or weight bearing. Since it involves a deviation in the sagittal and transversal planes, often combined with a malrotation, surgical correction can be challenging. We describe a case of splay toe deformity in the forefoot causing metatarsalgia in a 62-year-old female patient with a former avascular osteonecrosis of the 2 metatarsal head Smillie stage V of Freiberg-Köhler's disease causing a splay toe between the 2nd and the 3rd rays. There are only few reports in the literature, and a clear treatment strategy has not been defined, yet, although, it has been described that most of these patients are operated more than once. In the presented case, we performed a successful treatment by a combined surgical technique consisting in modified Weil's osteotomy and the transfer of the extensor brevis tendon. We sustain that for correction of a multiplanar deformity of lesser toe deformities osseous correction as well as tendon transfer lead to successful therapy.
