Arthroscopic interpositional arthroplasty for Freiberg's disease.

Abstract

Freiberg's disease is a relatively rare condition and can be difficult to manage, especially in those with late stages. Surgical treatment should be considered if conservative treatment cannot relieve the symptoms. We describe an arthroscopic interpositional arthroplasty for extensive late stages (stage IV or V) Freiberg's disease. Metatarsophalangeal arthroscopy is performed with dorsolateral and dorsomedial portals. Loose body is removed and joint surfaces are debrided. Extensor digitorum brevis tendon graft is harvested and rolled and brought into the joint. The technique is easy and can be performed on outpatient basis.
