Medium and Long Term Results of Modified Lindgren-Turan Osteotomy in the Treatment of Moderate and Severe Hallux Valgus

Abstract

Purpose: The aim of this study is to evaluate the clinical and radiologic outcomes of patients with moderate to severe hallux valgus (HV) who underwent capsuloplasty and buniectomy with Lindgren-Turan osteotomy. Materials and Methods: The outcomes of 71 patients who underwent Modified Lindgren-Turan procedure were evaluated in the medium and long term. Clinically, assessment was done using the American Orthopaedic Foot and Ankle Society (AOFAS) score and Visual Analog Scale (VAS). Radiologically, preoperative and postoperative measurements of hallux val-gus angle (HVA), distal metatarsal angle (DMAA), first-second intermetatarsal angle (IMA), and first metatarsal shortening were evaluated using X-ray. Patients with moderate (n=52) and severe (n=19) hallux valgus were divided into two groups. Results: The patients were followed up for an average of 52.76 ± 9.7 months (range: 38-78 months). Patients were divided into two groups: moderate HV (group 1) and severe HV (group 2). In both groups, statistically significant improvements were observed in HVA, IMA, and DMAA values (p < 0.001). There was a shortening observed in the first metatarsal in both groups, but no significant difference was found between the groups (p = 0.342). Clinically, significant improvements were also noted in AOFAS and VAS scores in both groups (p < 0.001). Conclusion: The Modified Lindgren-Turan osteotomy causes mild shortening of the metatarsal, which does not lead to any compli-cations. With this method, moderate and severe hallux valgus deformities can be corrected, and favorable clinical and radiological outcomes can be achieved.
