Biomechanical analysis of impending femoral neck fractures: the role of percutaneous cement augmentation for osteolytic lesions.

Background: Management of impending pathologic femoral neck fractures includes internal fixation, arthroplasty and megaprostheses. The study aim was to determine the augmentative effect of cement injection for minimally invasive treatment of femoral neck lesions.

Methods: Twenty-seven cadaveric femora received a simulated osteolytic lesion previously shown to decrease the femur's failure load by 50%.

Treatment and complications in orthopaedic trauma patients with symptomatic pulmonary embolism.

Objectives: The purpose of this study is to characterize the presentation, size, treatment, and complications of pulmonary embolism (PE) in a large series of orthopaedic trauma patients who developed PE after injury.

Methods: We reviewed the records of orthopaedic trauma patients who developed a PE within 6 months of injury at 9 trauma centers and 2 tertiary care facilities.

Results: There were 312 patients, 186 men and 126 women, average age 58 years.

Regeneration of a discoid meniscus after arthroscopic saucerization.

We report the case of a 5-year-old girl who presented to the clinic with recurrent knee pain after meniscal repair and saucerization at age 3. The finding of a regenerated discoid meniscus was confirmed arthroscopically and radiographically. To our knowledge, this is the first report in the literature to confirm regeneration of a discoid meniscus after saucerization.

Intraoperative radiation exposure with the use of (18)F-FDG-guided thyroid cancer surgery.

Radio-guided surgery is an established means for surgeons to identify a target of interest for biopsy or excision. This technique is used for a variety of malignancies as well as minimally invasive parathyroid surgery. The primary radionuclide used for these procedures is technetium-99m (Tc-99m), but others have been used.
