Primary Closure of External Fixator Pin Sites Is Safe After Orthopaedic Trauma Surgery.

Objectives: To determine if rates of pin site infection and surgical site infection among patients managed with primary closure after external fixator removal were similar to those allowed to heal secondarily.

Design: Retrospective cohort.

Setting: Urban/Suburban Academic Level I Trauma Center.

Locked Plating versus Nailing for Proximal Tibia Fractures: A Multicenter RCT.

Objectives: The main 2 forms of treatment for extraarticular proximal tibial fractures are intramedullary nailing (IMN) and locked lateral plating (LLP). The goal of this multicenter, randomized controlled trial was to determine whether there are significant differences in outcomes between these forms of treatment.

Design: Multicenter, randomized controlled trial.

Surgical management of U/H type sacral fractures: outcomes following iliosacral and lumbopelvic fixation.

Background: U and H-type sacral fractures are under diagnosed injuries resulting from significant axial loading that are often associated with neurological deficits. No studies to date have compared two common methods of surgical fixation, iliosacral screw fixation (ISF) and lumbopelvic fixation (LPF).

Methods: Patients with sacral fractures from 2009-2015 at one level 1 trauma center were identified by current procedural terminology (CPT) code and imaging reviewed for U/H type sacral fractures.

Radiographic Review of Helical Blade Versus Lag Screw Fixation for Cephalomedullary Nailing of Low-Energy Peritrochanteric Femur Fractures: There is a Difference in Cutout.

Objectives: To compare the rate of cutout of helical blades and lag screws in low-energy peritrochanteric femur fractures treated with a cephalomedullary nail (CMN).

Design: Retrospective review.

Setting: Academic medical center.

Fragility fractures requiring special consideration: pelvic insufficiency fractures.

Fractures of the pelvis and acetabulum in osteoporotic bone represent an important subset of fragility fractures. Pelvic fractures in the elderly patient carry a significant 1-year mortality risk, comparable to that of hip fractures. Patients often lose their ability to function independently in the community.

Murine model of oligotrophic tibial nonunion.

Objectives: This study aimed to use modified distraction osteogenesis techniques to develop a reliable mouse fracture nonunion model with an oligotrophic phenotype.

Methods: Twenty-six 10- to 14-week-old C57BL/6 male mice underwent a proximal diaphyseal tibial osteotomy with a 2-mm bone resection. An external fixation device was applied to the tibia using cerclage wires.

Locked plates reduce displacement of vertically unstable pelvic fractures in a Mechanical Testing Model.

Background: The purpose of this study is to compare a locked screw construct to a single iliosacral screw for fixation of a vertically unstable pelvic ring injury in a transforaminal sacral fracture model.

Methods: Orthopaedic Trauma Association type 61-C1.3a2c5 fractures were created in 10 fresh frozen cadaveric pelvis specimens.

Interobserver reliability of a CT-based fracture classification system.

Objectives: This study was designed to determine whether the interobserver reliability of a fracture classification scheme applied based on a single, carefully defined, computed tomography (CT) cut is greater than those previously reported for systems designed for use with plain radiographs.

Design: Observer review of selected cases.

Setting: Four, level one, trauma centers.
