Computed tomography-based comparison of the greater sigmoid notch restoration after tension-band wiring in osteotomized olecranon and transverse olecranon fracture
Abstract
Purpose To determine whether the restoration of greater sigmoid notch (GSN) congruity differs between osteotomized and simple fractured olecranon treated with tension-band wiring (TBW) using arc center distance (ACD) as a quantitative radiographic indicator. Methods We retrospectively evaluated 45 patients who underwent TBW with ring pins, including 23 who underwent olecranon osteotomy and 22 with Mayo type 2A olecranon fractures. Postoperative sagittal computed tomography images were analysed to measure ACD, articular gap, step-off, interfragmentary distance (IFD), and osteotomy angle. GSN was considered congruent when ACD was
