Arthroscopic Keller technique for Freiberg disease.

Freiberg disease is a disorder that has a predilection for the second metatarsal head. Keller excision of the base of the proximal phalanx is a procedure described for the treatment of late-stage Freiberg disease. We describe a case of a 60-year-old man, with a stage IV lesion according to Smillie's classification, treated by debridement, removal of the free body, and arthroscopic Keller excision. Arthroscopic treatment allows the patient to begin and maintain an aggressive postoperative physical therapy program immediately after surgery, thus decreasing the risk of scarring and contracture. At last evaluation, 2 years postoperatively, he is symptom-free. A suggested pattern of minimally invasive surgery management of this disease is proposed.
