Аннотация
BACKGROUND: Effects of procedural factors on chevron bunionectomy outcomes were studied.
METHODS: Included were 109 feet with distal chevron osteotomy and preoperative intermetatarsal angle (IMA) greater than 15 degrees. IMA and hallux valgus angles (HVA), release type, fixation, second-digit procedures, and risk factors were evaluated.
RESULTS: Eighty-three percent (91/109 feet) had satisfactory outcomes; nine had moderate pain. From preoperative, IMA improved 7.2 and HVA 20.5 degrees. Risk factors or second-digit procedures had no effect. Lateral release improved IMA (p < 0.01), with no difference between open lateral and transarticular release; 86% percent (64/74) were satisfied with open lateral release compared with 83% (19/23) and 66% (8/12) with no release and transarticular release, respectively. Fixation did not affect outcomes.
CONCLUSION: Chevron bunionectomy corrected IMA and HVA to normal with few complications. Lateral release increased IMA correction. Transarticular release had lower satisfaction than open lateral release or no release.
LEVEL OF EVIDENCE: Level III, retrospective.
