Case:
We report a rare case of polymetatarsia without polydactyly. Our patient presented with pain and difficulty with shoewear. Radiographs showed an accessory metatarsal arising from the lateral aspect of the fourth metatarsal proximal metaphysis, fusing distally with the medial aspect of the fifth metatarsal head to form a single metatarsophalangeal joint. He was treated with a chevron osteotomy of the conjoined complex and an Akins osteotomy of the fifth proximal phalanx. Our patient recovered functionally, and his pain improved postoperatively.
Conclusion:
The chevron osteotomy is an option for treating polymetatarsia without polydactyly with the aim of reducing the forefoot width.
Level Of Evidence:
Case study, level 5.
