Scarf osteotomy for correction of hallux valgus. Historical perspective, surgical technique, and results

Abstract

The Scarf osteotomy has proven to be a versatile and powerful procedure to correct various degrees of hallux valgus deformity. Through modifications of bone-cut lengths and in combination with a phalangeal osteotomy, most hallux valgus deformities can be addressed. In cases of extreme hypermobility of the first ray or arthrosis of the first metatarsocuneiform joint, the Lapidus operation may be more appropriate. Hallux valgus rigidus or hallux valgus with severe rheumatoid joint disease usually requires alternative procedures. The results of the Scarf osteotomy compare favorably with the results reported for other popular bunion surgeries. When choosing a procedure, the clinician should consider that the Scarf osteotomy allows the patient to ambulate postoperatively without a cast or the use of crutches, to return to bathing and a closed athletic shoe in one week, and to have bilateral surgery, which maintains cost-effectiveness and returns the patient to his or her desired lifestyle more quickly. It has been said that surgery is both a science and an art. The author often believes that bunion surgery is more art than science, hence the success of so many procedures in one surgeon's hands and the failure in another's hands. The Scarf bunionectomy is a technically demanding procedure that has a large learning curve. Once mastered, however, the Scarf bunionectomy can provide a predictable and satisfying outcome for both patient and foot surgeon.
