Benign Bone Tumors of the Hand: Beyond Enchondromas.

Beyond enchondromas, the most common bone tumors of the hand, there are numerous less common benign bone tumors and mimickers with which orthopaedic and hand surgeons should be familiar. These include other benign cartilage tumors, cystic lesions, osteogenic tumors, giant cell tumor, and fibrous dysplasia. Particularly unique lesions include bizarre parosteal osteochondromatous proliferation (Nora lesion), florid reactive periostitis, turret exostosis (acquired osteochondroma), giant cell reparative granuloma (solid aneurysmal bone cyst), and epidermoid cyst.

A Biomechanical Comparison of Fixation Techniques in Metacarpal Shaft Fractures.

 Typically, metacarpal shaft fractures are treated with closed reduction percutaneous pinning, intramedullary nails, or plate fixation. Recently some surgeons have begun using intramedullary headless compression screws.  The purpose of this study was to compare intramedullary screw fixation to K-wire fixation, which is the standard of care in a transverse metacarpal midshaft fracture, using a cadaveric model.

Dual-Mobility Articulations in Femoral Neck Fractures: A Systematic Review of the Literature and Meta-analysis of the Outcomes.

Introduction: Femoral neck fractures have been traditionally managed with hemiarthroplasty (HA) or conventional total hip arthroplasty (CTHA). There has been recent interest in using dual-mobility components (DMC) in total hip arthroplasty for patients with femoral neck fractures to provide increased stability and decrease the need for future revision.

Methods: We conducted a systematic review of the literature reporting on the use of DMC in the management of femoral neck fractures in geriatric patients.

Effect of Pedicle Fill on Axial Pullout Strength in Spinal Fixation After Rod Reduction.

Rod reduction to pedicle screws is used for a variety of spinal fixation procedures; however, it can alter the integrity of the screw-bone interface. The authors investigated the effect of pedicle fill (ratio of pedicle screw diameter to pedicle diameter) on the strength of the screw-bone interface after simulated rod reduction on 17 vertebrae (3 thoracolumbar spine specimens). Pedicle diameter was measured with standard clinical computed tomography scan protocols.
