Wang Z, Sun J, Yan J, et al. - In this study, the efficacy of posterior-anterior (PA), anterior-posterior (AP) screws, and PA plate in the fixation of posterior malleolar fractures (PMFs) with a fragment size of ≥ 15 and < 15% was explored. Researchers conducted a retrospective study including the clinical data of 243 patients with a unilateral ankle fracture involving the posterior malleolar ankle fracture. They classified all individuals into two groups based on their fragment size, ≥ 15% (n = 136), and < 15% (n = 107). No significant difference was found in the outcomes between the three fixation methods for PMFs with fragment size ≥15%. It was shown that the PA and AP screws both provided good fixation for PMF with fragmentation < 15%.
