Management of lumbar spondylolysis in the adolescent athlete: a review of over 200 cases.

Background: Spondylolysis is a defect of the pars interarticularis of vertebrae, most commonly seen at L5 and L4. The etiology of spondylolysis and isthmic spondylolisthesis is generally considered to be a result of repetitive mechanical stress to the weak portion of the vertebrae. A higher incidence of spondylolysis is observed in young athletes.

Foot and Ankle Injections in Athletes.

Context: Injections are commonly used by health care practitioners to treat foot and ankle injuries in athletes despite ongoing questions regarding efficacy and safety.

Evidence Acquisition: An extensive literature review was performed through MEDLINE, Google Scholar, and EBSCOhost from database inception to 2021. Keywords searched were , , , , , , and .

Altered tibiofemoral position following ACL reconstruction is associated with cartilage matrix changes: A voxel-based relaxometry analysis.

The purpose of this study was to analyze the relationship between postsurgical tibial translation (TT) and tibial rotation (TR) with cartilage matrix changes using quantitative magnetic resonance imaging, specifically voxel-based relaxometry with T1ρ and T2 mapping sequences. Knee magnetic resonance imaging's (MRI's) of 51 patients with unilateral anterior cruciate ligament injury, no concomitant ligamentous injury, history of osteoarthritis (OA), and previous knee surgery were scanned prior to surgery. Thirty-four patients completed follow-up MRI scans at 6-month, 1- and 2-year post-reconstruction and were included in this study.
