• Resumen

  • The sesamoid complex is located centrally and plantar to the first metatarsal head, where they are imbedded within the plantar plate, which transmits 50% of body weight and more than 300% during push-off, is susceptible to numerous pathologies. These pathologies include sesamoiditis, stress fracture, avascular necrosis, osteochondral fractures, and chondromalacia, and are secondary to these large weight-bearing loads. This article discusses sesamoid conditions and their relationship with hallux limitus, and reviews the conditions that predispose the first metatarsophalangeal joint to osteoarthritic changes.
