Combined chevron osteotomy and lateral capsuloligamentous release in treatment of hallux valgus

ABSTRACT

Twenty two patients with 34 bunions were treated surgically by exostectomy, lateral translation of the metatar-sal head after V- shaped osteotomy, a lateral release of the capsuloligamentous structures and reconstruction of the medial metatarsosesamoid ligament. The versatility of the osteotomy allows correction of the hallux valgus [HV] deformity by tilting the metatarsal head medially, dorsally and plantarwardly. Fixation by 2 k-wires added stability to the osteotomy site and allowed early rehabilitation. Tlie mean age of the patients was 41 years at time of operation. Most of our patients were females [91.9%]. The feet were evaluated clinically and radiologicaliy with a mean follow up period of 21 months [range from 10-36 months]. The mean correction of the hallux valgus angle was [13 WHITE BULLET] and of the intermetatarsal angle [6 WHITE BULLET]. Patient satisfaction was 95% as-regard bunion pain, and shoe. fitting. The American orthopedic foot and ankle society [AOFAS] scale [0-100] was used. The average value was 81.2 [ +/- SD 14.7] points according to the AOFAS rating system at the end of the study
