An Extraordinary Reconstruction of a Postoperative Defect after Metatarsophalangeal Joint Arthrodesis of the Big Toe Using the “Chinese Forearm Flap”

Abstract

Background We present an unusual technique for reconstruction of a postoperative tissue defect following hallux rigidus surgery.

Methods A complicated course after left big toe arthrodesis resulted in a soft tissue defect with bone exposure of the first ray. Amputation of the big toe was categorically rejected by the patient. There was advanced arteriosclerosis with single-vessel supply to the foot via the posterior tibial artery.

Outcome To preserve the big toe, the defect was covered by a fasciocutaneous radial free flap with a 15 cm long vascular pedicle which was microanastomosed to the posterior tibial artery and its accompanying vein at the level of the medial malleolus.

Conclusion In certain extreme situations, the free “Chinese” radial flap can be quite effective in covering forefoot defects and allowing satisfactory and aesthetically pleasing soft tissue reconstruction.

Key words
