Introduction: Treatment for Freiberg's disease is largely conservative. For severe disease and refractory cases, there are various surgical options. Most studies are from the Far-Eastern population and have short follow-up. The purpose of this study was to report the 5 year clinical outcomes of a dorsal closing wedge osteotomy in the treatment of advanced Freiberg´s disease in a Caucasian population.

Methods: Twelve patients (12 feet), with a mean age of 30.7 years (range 17-55), were treated with a synovectomy and a dorsal closing wedge osteotomy of the affected distal metatarsal. There were 10 females and 2 males. All patients were born in the United Kingdom. Clinical outcomes were independently evaluated pre and postoperatively using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and a subjective satisfaction score. Nine (75%) feet involved the 2^nd metatarsal and 3 feet (25%) involved the 3^rd metatarsal. According to the Smillie classification, 6 feet were Grade IV and 6 feet were grade V. Radiological union was evaluated postoperatively.

Results: No patients were lost to follow up and the mean follow-up time was 5.2 years (4-7). AOFAS scores improved from 48.1 +/- 7.4 to 88.9 +/- 10.1 postoperatively (p< 0.001) giving a mean improvement of 40.8. 92% of patients were satisfied with their operation at latest follow-up, reporting excellent or good results. All patients had postoperative radiological union. One patient had a superficial postoperative infection that was successfully treated with oral antibiotics.

Conclusions: A dorsal closing wedge osteotomy is an effective treatment of advanced Freiberg´s disease in a Caucasian population, with good outcomes and few complications.
