Stress Fracture of the Fifth Metatarsal After Evans' Calcaneal Osteotomy: A Report of Two Cases

Abstract

The Evans calcaneal lengthening osteotomy has gained popularity in recent years for the treatment of symptomatic flexible pes planus deformity. To our knowledge, the occurrence of a stress fracture of the fifth metatarsal has not been reported after this procedure. We report two such cases and discuss the probable mechanism of this problem, a relative overloading of the lateral aspect of the foot. Both cases were treated successfully with immobilization. Clinicians should be aware of this possible problem and treat it appropriately.
