Abstract
Hypothesis/Purpose: The Scarf osteotomy has gained popularity as treatment of choice in parts of Europe and is based on sound structural principles. The excellent results reported by others could not, however, be reproduced by the author and the results are presented. Methods: From January 1997 to June 1997 the Scarf osteotomy was selected in 20 consecutive patients (12 female and eight male patients, ages 18 to 60, mean: 41 years) with moderate metatarsus primus varus (IMA 13 to 20°) and hallux valgus deformities (less than 40°). The AOFAS Hallux Metatarsophalangeal-Interphalangeal Scale, visual analog scale and patient satisfaction were monitored prior to surgery, six and 12 months post-op. The patients were treated in a short leg cast, non-WB for two weeks followed by four weeks partial WB in a cast shoe. Routine post-bunion rehabilitation followed once the radiological and clinical diagnosis of healing was made. Results: Multiple complications were encountered. The most common was “troughing” of the metatarsal with loss of height. This occurred in seven patients (35%). Other complications include delayed union (5%), rotational malunion (30%), proximal fracture (10%), infection (5%) and early recurrence of deformity in 25%. All 20 patients were available for follow-up at six months, and 19 of 20 at 12 months. The AOFAS score pre-op was a mean of 53. At six months a mean of 54 (19 to 69) and at 12 months 62 (24–100). Forty-five percent (9/20) were unsatisfied at one year and would not recommend the surgery to a friend. Conclusions/Significance: The Scarf osteotomy has multiple potential pitfalls and should probably be reserved for moderate bunions in young people with good bone quality. There are multiple potential problems and the salvage of a failed Scarf osteotomy is difficult.
