title: Opening wedge osteotomy of the first cuneiform for the treatment of hallux valgus.
abstract: We performed an opening wedge osteotomy of the first cuneiform for the correction of all degrees of hallux valgus deformities. A wedge-shaped graft maintained the open wedge osteotomy and decreased the metatarsocuneiform joint inclination to correct the main angles of the hallux valgus. This procedure was performed for 101 feet of 63 patients (two men and 61 women). Fifteen feet benefited from a shortening of P1. The average age was 42 (16 to 84) years with a mean follow-up of 7.7 (1.5 to 14.8) years. We evaluated the M1-P1 and the M1-M2 angles, the joint congruency and the position of the lateral sesamoid. The clinical examination was graded by the AOFAS score which includes comprehensive assessment of pain, function and alignment and the subjective assessment of patients. The clinical AOFAS score improved from 35.24 points preoperatively to 86.36 postoperatively and from 33.25 to 88.03 points in severe deformity. The subjective rating was 44.44% excellent, 41.27% good, 9.52% fair and 4.76% poor. The M1-P1 angle improved from 29.38 degrees to 16.28 degrees and the M1-M2 angle from 14.36 degrees to 10.34 degrees . In the 42 severe feet deformity, these angles improved respectively from 45.58 degrees to 19.58 degrees and from 18.51 degrees to 11.16 degrees . This technique allowed an accurate correction of the main angles of hallux valgus with different degrees of deformity and avoided the complications related to different types of osteotomies achieved along the first metatarsal. After a long follow-up, we demonstrated a durable result while 86% of patients proved excellent and good results according to the AOFAS score.
