Pediatric Chondrosarcoma of the Sternum Resected with Thorascopic Assistance.

Background: Chondrosarcomas are a heterogeneous group of malignant neoplasms that arise from bones, cartilage or other soft tissues that produce cartilage and are commonly seen in the middle decades of life. Despite being the most common primary bone sarcoma in adults, chondrosacromas are rare in pediatric patients.

Case Report: We report the case of a six-year-old child with a painless enlarging sternal mass of which biopsy was consistent with low-grade surface chondrosarcoma.

Hyaluronic Acid Injections for Treatment of Advanced Osteoarthritis of the Knee: Utilization and Cost in a National Population Sample.

Background: The prevalence of knee osteoarthritis is increasing in the aging U.S.

Population: The efficacy and cost-effectiveness of the use of hyaluronic acid (HA) injections for the treatment of knee osteoarthritis are debated.

Gender Disparities in Osteoarthritis-Related Health Care Utilization Before Total Knee Arthroplasty.

Objectives: Women older than 50 years have higher prevalence of knee osteoarthritis (OA) and experience greater functional disability than men. No studies have examined large populations to identify knee OA-related health care utilization differences. The purpose of this investigation was to evaluate gender differences in the utilization of OA-related health care resources in the 12 months preceding total knee arthroplasty (TKA).

Anti-Osteoporotic Therapy After Fragility Fracture Lowers Rate of Subsequent Fracture: Analysis of a Large Population Sample.

Background: This investigation assessed the effectiveness of initiating anti-osteoporotic therapy after a fragility fracture in preventing subsequent fractures.

Methods: The Truven Health MarketScan databases, which contain de-identified, integrated, person-specific claim data, were queried from 2003 to 2012. The study population included individuals fifty years of age or older who sustained a fragility fracture, defined as any fracture of the wrist, proximal part of the humerus, hip, or vertebra, and had three years of continuous enrollment following fracture.

Predictors of range of motion in patients undergoing manipulation after TKA.

Background: Knee stiffness or limited range of motion (ROM) after total knee arthroplasty (TKA) may compromise patient function. Patients with stiffness are usually managed with manipulation under anesthesia (MUA) to improve ROM. However, the final ROM obtained is multifactorial and may depend on factors such as comorbidities, implant type, or the timing of MUA.
