The modified McBride technique is widely used in bunion surgery. The aim of this report is to analyze the influence that transferring the adductor hallucis tendon had on the first intermetatarsal angle (IMA), hallux abductus angle (HAA), and tibial sesamoid position (TSP) when used to correct the hallux valgus deformity. A prospective study was conducted of 31 hallux abducto valgus patients. A modified McBride procedure was performed to repair the deformity. In 16 patients (group 1), the adductor tendon was transferred, and in 15 (group 2), it was not. The tendon transfer was at random. The preoperative and postoperative variables IMA, HAA, and TSP were measured and analyzed by means of univariate and multivariate statistics. In group 1, the preoperative values of the first IMA and the HAA averaged 13.5 degrees and 30 degrees , respectively, decreasing postoperatively to 10.3 degrees and 10.7 degrees . In group 2, the corresponding preoperative angles were 12.9 degrees and 25.6 degrees , and the postoperative angles were 9.7 degrees and 10 degrees . There were no statistically significant differences between the 2 groups in the correction of the IMA, HAA, and TSP. As measured by the aforementioned radiographic measurements, there is no advantage in transferring the adductor hallucis tendon to the first metatarsophalangeal joint capsule in the correction of hallux valgus.
