The American Orthopaedic Foot and Ankle Society score and weight-bearing radiographs of the foot were applied to assess the feet pre- and postoperatively with a mean duration of follow-up of （38.2±3.2） months. The surgical procedure includes the release of the distal soft tissues, excision of the medial eminence, plication of the medial part of the capsule, and transfer of the EHL tendon, and reconstructing its insertion.Results At follow-up, 35 feet （23 patients, 85%） were free from pain at the first metatarsophalangeal （MTP） joint. In three feet （two patients）, the pain was alleviated but persisted. The mean hallux valgus angle decreased significantly from a preoperative 38.3°±8.0° to 7.3°±2.0° at the time of the most recent follow-up （P 〈0.0001）, and the mean intermetatarsal （IM） angle decreased significantly from preoperative 12.5°±3.4° to postoperative 6.5°±2.4° （P 〈0.0001）. The mean score according to the American Orthopaedic Foot and Ankle Society had increased from 46.5 to 84.8 points （P 〈0.0001）.Conclusions Hallux valgus can be corrected by transferring the EHL tendon medially and reconstructing its insertion.The technique can achieve stress balance of metatarsophalangeal joints and therefore prevent the recurrence of hallux valgus.展开更多
