Preliminary results of distal oblique first metatarsal osteotomy in hallux rigidus

Abstract

Objective: The objective of this study was to evaluate the resultsof distal oblique osteotomy for patients with Grade 2 hallux rigiduswith a long first metatarsal. Methods: Data from medical recordsof patients undergoing this treatment from March 2014 to March2016 were retrospectively collected. Assessment was based on theAOFAS scale and the level of patient satisfaction with the procedure.Postoperative radiographs were also analyzed in terms of joint space,length of the 1st metatarsal and first ray elevation measurement. Thefollow-up was up to 12 months after surgery. Results: The meanAOFAS score ranged from 44.6±8.6 to a final value of 88.7±3.9 score(pmean metatarsal length ranged from 50.3mm to 45.6mm (pand mean metatarsus primus elevatus ranged from 6mm to 1.2mm(pConclusion: The results of the study confirm that distal obliqueosteotomy is an effective procedure in the treatment of hallux rigidus,providing a significant improvement in joint function and a high levelof satisfaction with the procedure.
