Percutaneous Hallux Valgus Surgery: A Prospective Multicenter Study of 189 Cases

Distal first metatarsal osteotomies have been indicated for the correction of mild-to-moderate hallux valgus deformity. The aim of this study was to assess the clinical and radiographic results of the distal Reverdin–Isham first metatarsal osteotomy with use of a percutaneous procedure after a minimum 1-year followup. One hundred eighty-nine feet in 168 consecutive subjects were included in the present prospective multicenter study. A radiographic and clinical assessment using the American Orthopaedic Foot and Ankle Society's (AOFAS) hallux-metatarsophalangeal-interphalangeal scale was performed for all the subjects with a minimum 1-year follow-up. One hundred fifty six subjects (87%) were satisfied or very satisfied with the outcome of the procedure. The median postoperative AOFAS score was 93 points. Subjects averaged a loss 17% of first metatarsophalangeal joint motion. The median hallux valgus angle and intermetatarsal angle improved from 28° and 13° preoperatively, to 14° and 10° postoperatively, respectively. Percutaneous correction of mild-to-moderate hallux valgus deformity with the Reverdin–Isham osteotomy of the first metatarsal enables us to achieve clinical and radiographic results comparable to other percutaneous or open distal metatarsal osteotomies after 1-year follow-up.
