Reverdin-Isham osteotomy versus Endolog system for correction of moderate hallux valgus deformity: a Randomized Controlled Trial

Objectives. Several procedures have been described for the management of hallux valgus deformity. In this paper we would like to compare our experiences with two techniques (Endolog system and Reverdin-Isham osteotomy) with a randomized study. To our knowledge, this is the first study to be reported in the literature, that provides a detailed comparison of these two techniques to treat moderate hallux valgus.Materials and Methods. A total of 40 consecutive patients (40 feet) with moderate symptomatic hallux valgus were randomly assigned into two groups, to compare the results of Reverdin-Isham osteotomy (group A, 20 feet) and Endolog system (group B, 20 feet).Results. The average follow-up was of 23.7 +/- 7.7months. The average correction of HVA and IMA achieved in group A was 17.1 degrees +/- 6.2 degrees and 5.2 degrees +/- 2.6 degrees respectively, while in group B, it was 14 degrees +/- 6.2 degrees and 7.7 degrees +/- 2.6 degrees respectively. The mean AOFAS score improved from a pre-operative of 40.5 +/- 15.5 points to 90.3 +/- 5.3 points in group A, and from 32.4 +/- 16.8 points to 89.2 +/- 10.5 in group B.Conclusions. No statistically significant differences were detected between the two groups with respect to the AOFAS score, HVA, and IMA. Both groups showed good to excellent results.
