BACKGROUND Although the presence of numerous cell signaling receptors in osteosarcoma is known, their simultaneous characterization has not been performed to date. The current study sought to characterize and quantify the expression of cell surface receptors across a variety of osteosarcoma cell lines. METHODS Standard (n = 4) and patient-derived (n = 10)(More)
BACKGROUND It is not known whether the pattern of ulnar collateral ligament (UCL) tear affects elbow biomechanics. HYPOTHESIS There will be a significant change in elbow biomechanics with 50% proximal but not 50% distal simulated rupture of the UCL. STUDY DESIGN Controlled laboratory study. METHODS Pressure sensors in the posteromedial elbow joint of(More)
Ulnar collateral ligament insufficiency has been shown to result in changes in contact pressure and contact area in the posteromedial elbow. This study used new digital technology to assess the effect of a complete ulnar collateral ligament tear on ulnohumeral contact area, contact pressure, and valgus laxity throughout the throwing motion. Nine elbow(More)
