Abstract
Purpose.
To report outcome of Scarf osteotomy with or without proximal phalangeal osteotomy for correction of severe hallux valgus deformity.
Methods.
Records of 48 women and 4 men aged 28 to 68 (mean, 52) years who underwent 57 Scarf osteotomies with or without proximal phalangeal osteotomy for severe hallux valgus by a single surgeon were reviewed. The patients had a hallux valgus angle (HVA) of up to 55°. An additional proximal phalangeal osteotomy was performed in 11 of the patients whose hallux valgus persisted (HVA >10°). The American Orthopaedic Foot and Ankle Society (AOFAS) hallux score, the HVA and intermetatarsal angle (IMA) on radiographs, and the complication rate were assessed.
Results.
The mean follow-up period was 26 (range, 24–36) months. The mean AOFAS hallux score improved from 57.4 (range, 49–64) to 91.6 (range, 75–100). The mean HVA improved from 38.1° (range, 28°–52°) to 12.8° (range, 5°–20°). The mean IMA improved from 17.0° (range, 13°–24°) to 6.8° (range, 3°–10°). One patient developed chronic regional pain syndrome. There were no instances of non-union, delayed union, or malunion of the osteotomy site.
Conclusion.
Scarf osteotomy with or without proximal phalangeal osteotomy is an effective treatment for correcting severe hallux valgus deformity.
