Randomized Controlled Trial Multicenter Study
Are Locking Constructs in Distal Femoral Fractures Always Best? A Prospective Multicenter Randomized Controlled Trial Comparing the Less Invasive Stabilization System With the Minimally Invasive Dynamic Condylar Screw System.
The purpose of this clinical study is to determine whether the rate of fracture healing and fracture union, repaired with a locked device, will be as good as or better than standard nonlocking bicortical fixation in distal femoral fractures. ⋯ Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Anterior column percutaneous screw fixation can be challenging. The purpose of this new technique is to offer a rapid, simple, and safe method to place an anterior screw. The authors used a 3-dimensional reconstruction simulation, cadaver study, and a clinical case series to demonstrate this new alternative to standard previously described techniques.

Third-generation cephalomedullary nails currently represent the gold standard in the treatment of unstable trochanteric femur fractures. Recently, an extramedullary rotationally stable screw-anchor system (RoSA) has been developed. It was designed to combine the benefits of screw and blade and to improve stability using a locked trochanteric stabilizing plate (TSP). The purpose of this study was to compare the biomechanical behavior of RoSA/TSP and the proximal femoral nail antirotation (PFNA). ⋯ There was no significant difference in biomechanical properties between the RoSA/TSP and the PFNA for the fracture pattern tested. However, failure modes differed between the 2 implants with greater femoral neck shortening observed in the RoSA/TSP group.

Clinical Trial
Do Safe Radiographic Sacral Screw Pathways Exist in a Pediatric Patient Population and Do They Change with Age?
Iliosacral screw pathways in the first (S1) and second (S2) sacral segments are commonly used for adult pelvic ring stabilization. We hypothesize that radiographically "safe" pathways exist in pediatric patients. ⋯ Contrary to our hypothesis, almost all children aged 2-16 had a radiographically safe screw pathway for an iliosacral screw at S1, and most of the children had an available pathway for a TSTI screw at S2. However, only 51% had a pathway for a TSTI screw at S1.
