Background: A complicated foot positioning deformity known as hallux valgus can cause dysfunction, changed joint mechanics, and progressive discomfort, frequently at the medial eminence of the first metatarsophalangeal (MTP) joint. This study aimed to evaluate which is the best method for treating hallux valgus deformity between the medial opening wedge osteotomy and the dome osteotomy. Methods: this randomized controlled clinical trial, eighteen patients complaining of hallux valgus deformity after failure of conservative treatment were included in the study to undergo medial opening wedge osteotomy (group I), versus dome osteotomy (group II) for treatment of their hallux valgus deformity, with follow up of 6 months. Preoperative data were collected from the medical records of the patients including both clinical and radiological evaluation, all patients were operated and followed up at the Orthopedic Surgery Department. Results: Functional assessment was carried out using the American Orthopaedic Foot and Ankle Society (AOFAS) Score. The mean preoperative score was 46.3±2.7 (range, 43–50) and 44.6±4.1 (range, 40–52) in groups I and II, respectively. At 3-month follow-up, the mean score increased to 80.7±3.4 (range, 77–89) and 81.8±2.4 (range, 78–85) in groups I and II, respectively. At 6-month follow-up, a further increase was observed to mean score of 90.9±2.8 (range, 77–89) and 91.0±3.9 (range, 78–85) in groups I and II, respectively. (Bonferroni test, P<.001). Conclusion: The two methods of osteotomy seem to be more clinically effective for the management of hallux valgus deformity.
