Abstract:
BACKGROUND:Juvenile hallux valgus (JHV) frequently results in an impaired quality of life because of pain and deformity. We used a validated clinical score to investigate the efficacy of lateral hemiepiphysiodesis of the first metatarsal base as a treatment for JHV. METHODS:We conducted a prospective, nonrandomized, single center cohort study of children who underwent lateral hemiepiphysiodesis for 31-IV, with a clinical and radiologic follow-up of at least 2 years. The efficiency of the procedure was assessed with the Hallux Metatarsophalangeal Interphalangeal Scale (HMIS), the metatarsophalangeal angle (MPA), and intermetatarsal angle (IMA). RESULTS:Twelve patients (22 feet) with JHV were treated by lateral hemiepiphysiodesis between 2012 and 2015. Average age at surgery was 10 years, and average follow-up was 3.5 years. The average HMIS score increased from an average of 56 at baseline, to 92 at last follow-up ( p < 0.01). The average IMA decreased by 2°, from 13° preoperatively to 11° postoperatively. Average MPA decreased from 26° at baseline to 22° after surgery. No complications occurred in the immediate postoperative period, and no patient needed an additional procedure. CONCLUSION:The HMIS score was significantly improved after lateral hemiepiphyslodesis, with a clear improvement in pain and functional impairment at last follow-up. We noted a stabilization of the IMA and MPA, but the radiologic benefit did not reach statistical significance. Our data support the use of lateral hemiepiphysiodesis as an effective and safe treatment of JHV.
