Purpose:
The purpose of this study is to analyze the short- and long-term results of severe hallux valgus (HV) treated with a L-Reverse osteotomy.
Methods:
Patients treated with L-Reverse osteotomy for severe HV between the years 2006-2015 were included. Patients were evaluated preoperatively, at 3 months and 4 or more years postoperatively. Changes in the HV angle (HVA) and intermetatarsal angle (IMA) were measured. Clinical outcomes were assessed using the AOFAS score.
Results:
28 patients were included. Pre-operative IMA changed from 18.1° (18-18.9°) to 7° (6.3-8.5°), and HVA from 38.5° (34.5-41.3°) to 10.0° (8.4-11.8°) at 3 month follow up (p < 0.005). Long term follow up was of 5.6 (4.9-6.4) years. IMA value was 7.5° (6.1°-8.1°) and HVA was 10.1° (6.7°-16.3°), with no statistical difference with initial correction (p = 0.14). Median AOFAS score was 92.7 (89-4-96.1).
Conclusion:
L-Reverse osteotomy can achieve correction of HV severe deformities with good outcomes in long term follow up.
Level Of Evidence:
III.
