Hallux valgus: comparative study between two surgical techniques of proximal addition osteotomy.
OBJECTIVE
TO CLINICALLY AND RADIOGRAPHICALLY COMPARE THE RESULTS OF TREATMENT OF HALLUX VALGUS, BY TWO ADDITION OSTEOTOMY TECHNIQUES: one using resected exostosis, and the other using a plate fixation for addition wedge.


METHODS
We evaluated 24 feet of 19 patients, mean age 51.3 years, affected by hallux valgus, with a mean follow-up of 50.1 months. 13 feet underwent addition osteotomy with resected exostosis (AORE) and 11 patients (11 feet) underwent addition osteotomy with plate (AOP). The AOFAS score, intermetatarsal 1 and 2 angles, and hallux valgus angle were evaluated before and after surgery.


RESULTS
In the AORE technique, the mean preoperative AOFAS was 46.6, with IMA 14(o) and HVA 32o, while in the postoperative AOFAS it was 81.3, with IMA 9(o) and HVA 25(o), and 92.3% satisfactory results. In the AOP technique, the mean preoperative AOFAS was 42.1, with IMA 15(o) and HVA 29(o) while in the postoperative AOFAS it was 77.4, with IMA 11(o) and HVA 23(o) and 81.8% of satisfactory results.


CONCLUSIONS
Both techniques proved to be effective in the treatment of hallux valgus, both clinically and radiografically, with no statistical difference between them. Level of evidence III, Retrospective comparative study.
