Background:
There are many procedures described for the correction of severe hallux valgus. This is the first to examine the role of a basal osteotomy with distal soft tissue release.
Methods:
26 patients with severe hallux valgus underwent a basal chevron osteotomy with distal soft tissue release. All were reviewed at an average of 38 months.
Results:
The mean AOFAS score improved from 24 to 82 points (p<0.001). The IMA improved from an average of 23.90 to 130 (p<0.01). The HVA improved from an average of 490 to 170 (p<0.005). The correlation coefficient between the AOFAS score and various radiological angles was low (0.47).
Conclusions:
Good clinical outcomes in cases of severe hallux valgus can be achieved without full restoration of normal radiological values. Furthermore, a basal chevron osteotomy with a distal soft tissue release offers a high satisfaction rating with regards to both clinical and functional outcomes in the short to medium-term.
Level Of Evidence:
Level IV - Case series.
