Key takeaways:
- Minimally invasive chevron and Akin osteotomy showed improved patient-reported outcomes from preoperative testing to 5-year follow-up.
- Declines occurred between 2 and 5 years but were not clinically relevant.
Presented results showed minimally invasive chevron and Akin osteotomy may be an effective treatment for hallux valgus deformity correction.
At the American Orthopaedic Foot & Ankle Society Annual Meeting, David Gordon, MBChB, MRCS, MD, FRCS (Tr & Orth), presented results from a prospective, observational study that analyzed patient-reported data from 117 patients (169 feet) who underwent primary minimally invasive chevron and Akin osteotomy for hallux valgus deformities.
Gordon and colleagues followed a cohort of patients from a previous study with a 2-year follow-up out to 5 years and analyzed differences in patient-reported outcome measures (PROMs) over time. Outcome measures included the Manchester-Oxford Foot Questionnaire, the EuroQol-5D and VAS pain scores.
“All PROMs had a statistical improvement,” Gordon said in his presentation. “There was one that was not and that was the EQ-VAS, the overall health-rated quality of life score.”
Between 2 years and 5 years of follow-up, Gordon said there were slight declines in the walking and standing and social interaction domains of the Manchester-Oxford Foot Questionnaire, as well as the overall index and VAS pain scores.
However, Gordon said that despite the worsening in scores, this was not found to be clinically relevant based on the minimal clinically important difference.
“In conclusion, there were significant improvements in PROMs at the mean [follow-up] of 6.7 years after fourth-generation [minimally invasive chevron and Akin] MICA and a small decline, but probably not clinically significant, between 2 and 5 years,” Gordon said.
