Dislocation of the Fifth Metatarsal Base Following Partial Fourth and Fifth Ray Amputation

This case report presents a rare postoperative dislocation of the fifth metatarsal base following a healed open partial fourth and fifth ray amputation of a 62-year-old male veteran with poorly controlled diabetes mellitus. The dislocated fifth metatarsal base subsequently created a chronic ulceration and an inhibition of normal gait. The patient was taken to the operating room where the fifth metatarsal base was resected with transfer of the peroneus brevis tendon to the cuboid to maintain biomechanical stability.
