Hallux valgus is a common condition often leading to significant symptoms. However, its correction has recently been suggested, to be a procedure of limited clinical value. Scarf osteotomy is one of the most commonly performed operations for hallux valgus correction. Although technically demanding, it is powerful in its capacity to correct the hallux valgus deformity and sufficiently robust with internal fixation to allow early weight bearing.

We prospectively collected data for consecutive scarf osteotomies between 2008 and 2011. Preoperative and 6 week postoperative assessment was made using radiographic measurements HVA (hallux-valgus angle) and IMA (inter metatarsal angle). We evaluated 130 scarf osteotomies. The mean HVA improved from 29.5 pre-operatively to 12.6 post correction. The mean IMA improved from 12.4 pre-operatively to 8.1 post correction. The AOFAS hallux scores improved from an average of 55 pre op to 79 post operation.

The results suggest that hallux valgus correction does have clinical value and that scarf osteotomy is a reproducible procedure, with a generally good to excellent results in the short term.
