Causes and Treatments of Wrist Instability. With WH Short, LG Sutton:
Our long term goal is to understand the role of soft tissue structures in stabilizing the wrist joint and to optimize surgical treatments. Using a wrist joint motion simulator, changes in scaphoid and lunate kinematics are measured and animated to differentiate between the roles of various structures and repairs.
Biomechanical Evaluation of Ulnar Carpal Impaction. With BJ Harley, LG Sutton:
Ulnar Impaction is a disorder in which the distal ulna impacts against the carpal bones causing ulnar sided wrist pain, tenderness and often decreased grip strength. To determine which factors cause excessive ulnar loading, a dynamic biomechanical cadaver model is being used to measure load transfer across the wrist joint and the distal radioulnar joint.
Evaluation of Surgical Treatments of the Wrist. With BJ Harley, AK Palmer, WH Short, LG Sutton:
Surgical treatments for the wrist such as proximal row carpectomy, 4 corner fusion, total wrist replacement and cubital tunnel release are being studied using various biomechanical models.
Dynamic, Cyclic testing of Total Knee Replacements and Surgical Treatments of the Knee Joint. With JP Cannizzaro, MG Scuderi, LG Sutton:
Two dynamic knee simulators are used to move cadaver knees through either gait or deep knee bend motions. These simulators are used to quantify either kinematic or contact pressure changes due to releasing various ligaments, cartilage coring or the use of a knee replacement.
Shoulder and Elbow Biomechanics. With K Setter, LG Sutton:
Experimental and analytical models are used to evaluate shoulder implant fixation and stability and elbow ligament repair methods.
