From January 2014 to May 2015 a total of 12 females and 2 males (14 feet) were enrolled in the study (mean age 41.9±13.28). The inclusion criteria were patients with HV surgically treated with the percutaneous approach, mild or moderate not symptomatic PP at 24 months follow-up.
Percutaneous distal metatarsal osteotomy and exostectomy is performed for all patients and followed by a weekly bandage.
American Orthopaedic Foot and Ankle Society (AOFAS) score for HV (AOFAS-HV), patient satisfaction, and preoperative and postoperative X-ray at 6 weeks follow-up were evaluated. Numerical data are reported as the mean± SD and 95% confidence intervals. The pre-operative hallux valgus angle (HVA) was 30.14°±11.26°, the post-operative HVA was 18.36°±10.13 with a mean correction of 11.79°±2.67° with p<0.0001. Mean AOFAS-HV increased from 42.07±10.82 pre-operatively to 83±8.96 post-operatively with p<0.0001.
One out of 14 patients had recurrence of HV without needing revision surgery at the last follow-up. All patients were satisfied with the clinical outcomes.
Our results suggested that percutaneous osteotomy with the mini-burr is an effective treatment for patients with HV despite PP presence, even if the mean functional score was slightly worse when compared with the literature.
