A Comparative Study of Mini-Scarf Versus Standard Scarf Osteotomy for Hallux Valgus Correction.

Scarf osteotomy is widely used for hallux valgus treatment. More recently, a trend has begun toward the use of minimally invasive techniques, including the mini-scarf osteotomy, in which the diaphyseal cut is shortened. We compared the mini-scarf and traditional scarf osteotomy to determine whether the mini-scarf osteotomy is as effective as the scarf osteotomy in correcting mild to moderate hallux valgus and improving clinical function. We reviewed the cases of 37 consecutive patients during a 2-year period. A total of 21 (56.8%) patients had undergone scarf osteotomy and 16 (43.2%) had undergone mini-scarf osteotomy. The intermetatarsal, hallux valgus, and distal metatarsal articular angles and medial sesamoid position of the 2 groups were measured at 12 weeks postoperatively. The Manchester Oxford Foot Questionnaire scores and patient satisfaction were recorded at 28 months postoperatively. All radiologic parameters and Manchester Oxford Foot Questionnaire scores had significantly improved in both groups (p < .05 and p < .01 for mini-scarf and scarf, respectively). The medial sesamoid position had improved in all patients, with similar satisfaction between the 2 procedures (p = .43). The results of the present study have shown that the mini-scarf osteotomy for mild to moderate hallux valgus is as effective as the standard approach, with the potential benefit of a smaller scar and less soft tissue disruption.
