Abstract
This study observed the differences between 2 adductor hallucis release techniques (nonreattachment vs reattachment) in 4- to 8-year follow-up outcomes of scarf osteotomy combined with distal soft tissue release (DSTR) in moderate to severe hallux valgus correction. A retrospective review of moderate to severe hallux valgus patients treated with scarf osteotomy with DSTR was conducted. The patients were divided into 2 groups based on adductor hallucis release techniques (without and with reattachment to the metatarsophalangeal joint capsule). The demographic-matching process divided the samples into 27 patients per group. A comparison of last follow-up of clinical foot ankle ability measure (FAAM) for activity of daily living (ADL) and numerical rating scale for pain during 2 hours of ADL and radiographic outcomes (hallux valgus angle (HVA) and intermetatarsal angle (IMA) was analyzed. A p < .05 was considered a statistically significant difference. The final follow-up of FAAM for ADL was statistically better in the reattachment group as the median was 79.0 (IQR = 4.00) versus 76.0 (IQR = 4.00), p = .047. However, this difference did not achieve minimal clinical importance difference (MCID). The last follow-up of IMA was also statistically better in the reattachment group as the mean was 7.67 (SD = 3.10) versus 10.5 (SD = 3.59), p = .003. DSTR with adductor hallucis reattachment has statistically better IMA correction and maintenance than nonreattachment for moderate to severe hallux valgus correction using scarf osteotomy at 4- to 8-years follow-up. However, the better clinical outcomes did not achieve MCID.
