Abstract
In this study, the results of arthrodesis application with a single headless compression screw and a plaster in the shape of a bootie patients with hallux rigidus were evaluated. Operated with the diagnosis of hallux rigidus between December 2017 and July 2019; Arthrodesis was performed on 13 feet of 12 patients. During the operation, resection was performed to remove the cartilage tissues of the proximal phalanx and the first metatarsal joint surfaces. Arthrodesis was applied with a headless cannulated compression screw, followed by plaster in the form of a bootie. Hallux valgus and first finger dorsiflexion angles were measured by radiographic evaluations before and after surgery. The patients were clinically evaluated with the American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal scale. The patients were followed up for an average of 11.6 months. According to the AOFAS score, eight feet were excellent, three feet were good, and two feet were moderate in the last follow-up. An average of 39.8-point increase in AOFAS score was obtained compared to preoperative (p=0.001). In radiological evaluation, an average of 13° decrease was observed in the angle of hallux valgus, while a 2° increase was observed in the angle of dorsiflexion. As a complication, nonunion developed in two feet. None of the patients developed infection at the wound site and necrosis of the skin. Arthrodesis applied with a headless compression screw and a plaster cast in hallux rigidus surgery is a suitable treatment method for patients with advanced stage arthrosis.
