【 摘 要 】

Category:Midfoot/ForefootIntroduction/Purpose:Hallux rigidus occurs in up to 1 in 40 adults with 1st MTPJ arthrodesis being the gold standard operation for advanced disease. Our aim was to retrospectively identify risk factors for delayed / non-union of first metatarsophalangeal joint arthrodesis using a dorsal plate with cross screw.Methods:Case note and radiograph analysis was performed for operations between April 2014 and April 2016 with at least 6 months post-operative follow up. Union was defined as bridging bone across the fusion site on AP and lateral radiographic views with no movement or pain at the MTPJ on examination. All patients operations were performed or directly supervised by one of three fellowship trained consultant foot surgeons. Surgery was performed through a dorsal approach using a dorsal locking plate with compression screw. Blinded preoperative AP radiographs were analysed for the presence of a severe hallux valgus angle equal to or above 40 degrees. Intra-observer reliability wa...
