Shoulder Lesions Do Not Increase Inflammatory Biomarkers in Patients Undergoing Surgery for Glenohumeral Instability: An Exploratory Study.

Circulating protein biomarkers have demonstrated utility as a diagnostic tool in predicting musculoskeletal disease severity, but their utility in the evaluation of shoulder lesions associated with shoulder instability is unknown. Thus, the purpose of this exploratory study was to determine whether preoperative biomarkers of cartilage turnover and inflammation are associated with specific shoulder lesions in shoulder instability. Thirty-three patients (29.

Posterior Tibial Tendon Transfer for Common Peroneal Nerve Injury.

Common peroneal nerve dysfunction after a multiligament knee injury can be devastating. In patients with persistent foot drop, posterior tibial tendon transfer to the dorsum of the foot is a reliable and safe procedure to restore dorsiflexion. These authors favor passing the posterior tibial tendon through the interosseous membrane and docking it into the lateral/middle cuneiforms.

False-positive Cultures After Native Knee Aspiration: True or False.

Background: Synovial fluid aspiration is a routine practice used by most orthopaedic surgeons to aid in the diagnosis of joint infection. In patients for whom there is a low pretest probability of infection, a positive culture-particularly if it is a broth-only culture-may be considered a contaminant, especially if the bacterial species are skin pathogens. To our knowledge no study has evaluated the incidence of contamination of aspirations from the native knee.

Deep vein thrombosis in lumbar spinal fusion: a prospective study of antiembolic and pneumatic compression stockings.

We prospectively studied the incidence of deep vein thrombosis (DVT) of the thigh in 117 patients having posterior lumbar spinal fusion with instrumentation and bone grafting for degenerative disk disease or spondylolisthesis. Patients with neoplasm, infection, trauma, or history of DVT were excluded. Patients were randomized into two groups.
