First metatarsophalangeal joint arthritis can stem from a biomechanical imbalance as in hallux abducto valgus, metabolic arthritidies such as rheumatoid or gout, and even in posttraumatic cases. Advanced arthritis in the foot and ankle can often become debilitating. Surgical intervention is often necessary. Revision of failed first metatarsophalangeal joint arthroplasty is often in the setting of bony erosion and lysis, cystic changes, and loss of bone stock. In this article, we describe first metatarsophalangeal distraction arthrodesis technique using tricortical calcaneus autograft with the aim of simplifying donor site graft harvesting and decreasing donor site morbidity while attaining successful osseous union.
Levels of evidence: Level V.
