Abstract
Purpose: The evaluation of midterm results of a proposed surgical technique for the correction of hallux valgus deformity.
Material-Methods: Fifty-one female patients with sixty-two hallux valgus deformities were operatively treated between 1997–2002. The average age was 54.9 years and the mean follow up period was 32.7 months. A modified – 90 degrees angled – chevron osteotomy fixed with a Hebert screw was performed in all patients. Concomitant lesser toes abnormalities were managed at the same time. Preoperative, postoperative and last follow up radiographic intermetatarsal (IMA) and hallux valgus (HVA) angles, were measured and compared. Subjective analysis consisting of the AOFAS hallux scale was performed.
Results: The averaged preoperative HVA was 34.1 (range 22–56) and the averaged IMA 15.5 (range 10–29). The corresponding postoperative angles were 14.2 (range 0–28) and 8.1 (range 6–22). The mean AOFAS score was 94.3 (65–100). All the osteotomies were fused and there was not any case of non-union or loosening. Two patients showed late recurrence of the deformity but refused any further treatment.
Conclusions: Hebert screw is a reliable fixation method of the chevron osteotomy for the treatment of hallux valgus. The osteotomy site is firmly secured, avoiding early displacement of the lateral fragment.
