Zhang K, Cui R, Gu Y, et al. - This study was sought to compare the clinical outcomes of posteroanterior (PA) lag screws versus posterior buttress plate fixation in treatment of posterior malleolar fragments (PMFs) in spiral tibial shaft fracture, and provide guidance for surgeons selecting a treatment strategy. Researchers enrolled a total of 48 eligible patients with PMFs associated with spiral tibial shaft fracture surgically treated from March 2009 to January 2016. Individuals were classified into the screw group (n = 24) and the plate group (n = 24). There were no significant differences between the groups in injured/contralateral ankle ROM or posttraumatic ankle arthritis scale postoperatively. The results indicate that, via a posterolateral approach, the PA lag screws or posterior buttress plate fixation can achieve good and equivalent clinical and radiological outcomes with minimal complications for PMFs in spiral tibial shaft fracture, .
