Chen J, Ju J, Ma M, et al. - This study was intended to ascertain fracture line morphology of the greater tuberosity (GT) fragment of Neer 3 or 4 part proximal humerus fracture (PHF) and examine the location relationship between the locking plate and the GT fragment. Researchers retrospectively examined 71 three-dimensional computed tomography scans of Neer 3 and 4 part PHF. They distinguished common sites of the GT fracture, and the location relationship between the locking plate and GT fragments was examined in a computer-simulated scenario. The data exhibited that the fracture line morphology of GT fragments of Neer 3 and 4 part PHF was in a fan shape. GT fragments could be categorized based on their location and morphology. The outcomes of this study demonstrated that the extent of GT fragment coverage provided by the locking plate differed in various fragment types, and preoperative evaluation of fragment type might help design surgical plans.
