BACKGROUND Conventional wrist joint goniometry evaluates range of motion in isolated directions. The coupling between wrist flexion-extension and radial-ulnar deviation was investigated. METHODS Ten healthy young male subjects performed wrist flexion-extension, radial-ulnar deviation, and circumduction motions. Flexion-extension and radial-ulnar deviation(More)
Elbow joint stiffness is critical to positioning the hand. Abnormal elbow joint stiffness may affect a person's ability to participate in activities of daily living. In this work, elbow joint stiffness was measured in ten healthy young adults with a device adapted from one previously used to measure stiffness in other joints. Measurements of elbow stiffness(More)
Animal models for orthopaedic implant testing are well-established but morphologically dissimilar to human tibiae; notably, most are shorter. The purpose of this study was to quantitatively evaluate the morphology and mechanical properties of the cervine tibia, particularly with regard to its suitability for testing orthopaedic implants. Two endosteal and(More)
Approximately 50% of women and 25% of men will have an osteoporosis-related fracture after the age of 50, yet the micromechanical origin of these fractures remains unclear. Preventing these fractures requires an understanding of compression fracture formation in vertebral cancellous bone. The immediate research goal was to create clinically relevant(More)
Animal joints are valuable proxies for those of humans in biomechanical studies, however commonly used quadruped knees differ greatly from human knees in scale and morphometry. To test the suitability of the cervine stifle joint (deer knee) as a laboratory model, gross morphometry, ACL cross section, and ACL rupture strength were measured and compared to(More)
Many aspects of the performance of different implant designs remain as open questions in total hip arthroplasty. Despite the increased survivorship of each hip replacement, the amount of bone removed during surgery remains an important factor because of the potential need for revision surgery. Given that a smaller implant will have less surface area over(More)
A rapid prototyping model of Mason II fracture was used to investigate baseline recommendations for surgical intervention founded on kinematic forearm rotational blockage. Exact replicas of the radial heads in nine cadaveric specimens were produced and specimens were tested in a physiologic elbow simulator. After testing supination/pronation, the rotations(More)
Current engineering pedagogy primarily focuses on developing technical proficiency and problem solving skills; the peer-review process for sharing new research results is often overlooked. The use of a collaborative classroom journal club can engage students with the excitement of scientific discovery and the process of dissemination of research results,(More)
BACKGROUND Total ankle arthroplasty (TAA) is becoming an effective treatment for end-stage ankle arthritis. It is unknown if TAA alters the patient's ability to sense ankle joint position. MATERIALS AND METHODS Thirteen unilateral TAA patients with a minimum of 2-years followup completed proprioceptive testing of the TAA and the contralateral side. The(More)
Developing appropriate mathematical models for biological soft tissues such as ligaments, tendons, and menisci is challenging. Stress-strain behavior of these tissues is known to be continuous and characterized by an exponential toe region followed by a linear elastic region. The conventional curve-fitting technique applies a linear curve to the elastic(More)
