Surgical treatment of acetabular fractures with plate fixation is challenging for orthopaedic surgeons because of variations of the surface curvature and complex fracture patterns of the acetabulum. We present our experience with pre-operative computer-assisted virtual simulation and three-dimensional (3D) printing techniques for the surgical treatment of acetabular fractures, especially in terms of operative time and surgical outcomes. ⋯ The 3D printing is a reliable method for treating acetabular fractures, and can reduce the surgical duration, instrumentation time, and blood loss.

Meta Analysis Comparative Study
Contemporary cemented versus uncemented hemiarthroplasty for the treatment of displaced intracapsular hip fractures: a meta-analysis of forty-two thousand forty-six hips.
Controversy exists regarding the use of cement for hemiarthroplasty to treat displaced intracapsular hip fractures. The aim of this systematic review and meta-analysis was to compare the clinical outcomes between contemporary cemented and contemporary uncemented hemiarthroplasty for the treatment of displaced femoral neck fractures. ⋯ This meta-analysis shows that contemporary cemented prostheses have less intra-operative and post-operative fractures, but longer operative time, more intra-operative blood loss, and heterotopic ossifications. Otherwise, there were no significant differences between both groups.

Given the recent controversy in the literature and the alarming reports of early mechanical failure associated with the use of the Synthes 4.5 mm VA-LCP Curved Condylar Plate in acute distal femur fractures, the goal of our study was to examine the outcomes and mechanical failure rates of this implant in a larger patient population. ⋯ In our experience, the Synthes 4.5 mm VA-LCP Curved Condylar Plate is a safe and effective implant with a relatively low mechanical failure rate.

Randomized Controlled Trial Comparative Study
Comparison of clinical results between novel percutaneous pedicle screw and traditional open pedicle screw fixation for thoracolumbar fractures without neurological deficit.
To compare the efficacy and safety of novel percutaneous minimally invasive pedicle screw fixation and traditional open surgery for thoracolumbar fractures without neurological deficit. ⋯ Novel percutaneous pedicle screws with angle reset function can achieve the same effect as traditional open pedicle screw fixation in the treatment of thoracolumbar fractures without nerve injuries. Percutaneous minimally invasive pedicle screw fixation has the characteristics of shorter operative time, less bleeding, and less pain, but it needs more radiation times.

Occult intra-operative periprosthetic acetabular fracture is a seldom-reported complication of primary total hip arthroplasty (THA). It may potentially be associated with cup instability and implant loosening. The present study aimed to investigate clinical consequences of this complication. ⋯ Central wall acetabular fractures, although unrecognized intra- and post-operatively may impair implant survival after THA.
