Far cortical locking versus standard locking screw fixation in simulated femoral fractures: A biomechanical meta-analysis.

Introduction: Far cortical locking (FCL) is a concept of locking plate fixation with reduced stiffness and symmetric micromotion to improve callus formation. The goal of our study was to review biomechanical data evaluating FCL plate and screw fixation versus standard locking (SL) plate and screw fixation by analyzing studies of cadaveric and synthetic bone models to draw biomechanical conclusions.

Methods: Biomechanical studies that compared FCL and SL plate fixation for simulated femoral fractures were reviewed for construct stiffness, load to failure, axial motion at the near and far cortices, and the difference between near and far cortical axial motion to demonstrate motion symmetry.

Operating Room and Hospital Air Environment.

One method of preventing surgical-site infection is lowering intraoperative environmental contamination. The authors sought to evaluate their hospital's operating room (OR) contamination rate and compare it with the remainder of the hospital. They tested environmental contamination in preoperative, intraoperative, and postoperative settings for a total joint arthroplasty patient.

Implications of positive urine toxicology screening in trauma patients.

Background: Pain management in trauma patients can be difficult due to their varied injuries and presence or absence of illicit substances in their systems. Additionally, trauma patients have variable lengths of stay. Limiting length of stay to what is medically necessary and preventing long-term dependence on narcotic medications are important in trauma patient care.

Transbrachioradialis Approach to the Radial Tunnel: An Anatomic Study of 5 Potential Compression Sites.

Background: Recent anatomic studies have failed to demonstrate a single utilitarian approach to intraoperative identification and surgical release of all 5 potential sites of posterior interosseous nerve (PIN) compression in the radial tunnel. This study examines if a single incision brachioradialis-splitting approach without the use of additional anatomic windows is capable of adequately exposing the entire length of the radial tunnel, including all 5 sites of PIN compression to allow for adequate release.

Methods: Ten fresh frozen cadaver forearms (6 female, 4 male) were dissected utilizing a curvilinear 7 cm incision over the brachioradialis.

Nonunion of a Nondisplaced Radial Neck Fracture: A Case Report.

Case: We describe the case of a 66-year-old man who sustained a nondisplaced radial neck fracture and subsequently developed a symptomatic nonunion. After a period of unsuccessful conservative treatment, a radial head resection was performed.

Conclusion: Radial neck fractures, unlike their radial head counterparts, have a low rate of nonunion.

The Current Knowledge on Spinopelvic Mobility.

Recent studies may suggest that our conventional knowledge of risk factors for dislocation may need rethinking. Previous studies have demonstrated a large majority of total hip arthroplasty instability with acetabular cups implanted in safe zones. Recently discovered spinopelvic motion is a coordinated biomechanical relationship among acetabular anteversion, pelvic tilt, and lumbar lordosis.

Single incision pediatric flexible intramedullary tibial nailing.

Background: There has been a trend towards flexible intramedullary nailing for unstable tibial shaft fractures in the pediatric population, traditionally, utilizing a 2-incision technique with passage of one nail medially and one nail laterally. Our study aims to compare a single incision approach for flexible nailing of unstable tibial shaft fractures in pediatric patients to the traditional 2-incision approach.

Methods: Patients were selected for operative fixation if they had a length unstable tibial shaft fracture confirmed by fluoroscopy.

Radiographic Outcomes of Dorsal Distraction Distal Radius Plating for Fractures With Dorsal Marginal Impaction.

The purpose of this study is to compare radiographic outcomes of patients treated with dorsal spanning plates with previously reported normal values of radiographic distal radius anatomy and compare the results with prior publications for both external fixation and internal fixation with volar locked plates. Patients with complex distal radius fractures including dorsal marginal impaction pattern necessitating dorsal distraction plating at the discretion of the senior authors (M.A.
