Scarf osteotomy for hallux valgus correction. Local anatomy, surgical technique, and combination with other forefoot procedures.
At first, scarf osteotomy can be technically demanding. The aim of the author has been to develop an efficient technique, make it easier and more accurate, and to achieve immediate reproducibility of results. Neither the skin incision nor the length of the osteotomy result in postoperative edema, whereas the strong fixation enables very early functional recovery. Complications are rare and avoidable. The sum of the scarf's advantages results in a reliable surgical procedure. The scarf osteotomy is extremely versatile, because it allows a wide range of fragment displacement. This is why the scarf is not a single osteotomy but several. This means its indications are broad, from mild to the most advanced deformities, including arthritic, juvenile, iatrogenic, and even rheumatoid hallux valgus. The contraindications of scarf osteotomy are a very large hallux valgus deformity with a very thin first metatarsal; extremely deformed MPT joint, and hallux valgus combined with a severe pes planus and hypermobility of the first metatarsal (the Lapidus procedure is preferable at this stage). Finally, we should remember the two following points: 1. Whatever the indication, the scarf first metatarsal osteotomy is only one of the four steps necessary for correcting hallux valgus deformity: a) MTP lateral release, b) Scarf osteotomy, c) medial capsulorraphy, and d) great toe proximal osteotomy. 2. The scarf is just one element of the different procedures, including the Weil lesser ray osteotomy, which allow precise forefoot management according to each static disorder. These techniques have very significantly extended the indications for most static disorders where corrective surgery preserves the joints and their mobility.
