Surgical treatment of mild to moderate hallux valgus by percutaneous Akin technique with exostectomy and lateral release

Abstract

Objective: To present clinical and radiographic results of surgical correction of mild to moderate hallux valgus using the modified percutaneous Akin technique with exostectomy and lateral release. Methods: We evaluated prospectively 24 feet from 15 patients with mild to moderate hallux valgus, considering a hallux valgus angle from 12° to 30°, intermetatarsal angle from 8° to 15°, and distal metatarsal angle Results: The mean AOFAS score from 55.6 became 94.2 after surgery. The mean hallux valgus angle from 21° (15° to 27°) became 9.2° (4° to 21°), and the intermetatarsal angle from 11.2° (6° to 15°) became 10.3° (8° to 13°). All patients reported satisfaction with the result. Conclusion: Surgical technique described was effective to treat mild to moderate hallux valgus with improvement of the AOFAS score, higher level of patient satisfaction, good radiographic corrections and lower surgical aggression.
