Trauma can render the elbow unstable via a combination of bone and ligament injuries. Some of these injuries feature subluxation rather than dislocation of the elbow. Effective treatment centers on restoring enough of the bony and ligamentous structures to keep the elbow in joint so that recovery can proceed as for a simple elbow dislocation. Recognition of distinct patterns of injury can help ...

BACKGROUND With improving surgical techniques for total elbow arthroplasty clinical outcomes have improved and its utilization continues to increase. Despite these advances, complication rates remain as high as 24%. Of these complications periprosthetic joint infection is one of the most common and morbid. The rheumatoid elbow remains a leading indication for total elbow arthroplasty. Patients ...

The present study focuses on geometric features of workspace and joint-space paths of three-dimensional reaching movements. Twelve subjects repeatedly performed a three-segment, triangular-shaped movement pattern in an approximately 60 degrees tilted horizontal plane. Task variables elicited movement patterns that varied in position, rotational direction and speed. Trunk, arm, hand and finger-t...

Painful arthritis of the elbow joint has long been a challenging problem. Elbow arthroplasty has emerged as viable treatment method for many patients. Implant design and surgical technique have evolved to provide more predict-able symptom relief without compromising function. Elbow arthroplasty can now be used to treat a wide variety of conditions, including osteoarthritis, rheumatoid arthritis...

Tuberculosis remains a major health issue worldwide, with a growing incidence in the UK; 8500 new cases were reported in 2006. However, musculoskeletal involvement is still infrequently reported in the medical literature, especially in the developed world. The lack of familiarity with tuberculosis in general, as well as specific signs and symptoms of extrapulmonary involvement may be contributo...

OBJECTIVE To evaluate normal healthy persons without spasticity to observe normal findings of the elbow stretch reflex using a newly developed, portable, hand-driven spasticity-measuring system. METHOD Thirty normal persons without any disease involving the central or peripheral nervous system were enrolled in this study. The portable hand-driven isokinetic system is able to measure the joint...

Objective: To determine the net moments on the glenohueral joint and elbow joint during wheelchair activities. Design: Kinematics and external forces were measured durng wheelchair activities of daily living (level propulsion, iding on a slope, weight-relief lifting, reaching, negotiating a urb) and processed in an inverse dynamics biomechanic odel. Setting: Biomechanics laboratory. Participant...

The elements of an algorithm are presented which predicts for some simple forms (circles and ellipses) the kinematic and figural aspects of the trajectories of the human wrist when these are drawn in any arbitrary plane of free, three-dimensional space. The algorithm is based on theoretical considerations and experimental data and specifies in a unique way the angular motion at the shoulder and...

The paper presents the results of comparative studies on the range of active elbow joint motion based on data obtained from 50 physical education students. The measurements were made with both an electrogoniometer and a manual goniometer. An explanation of differences in measurement results has been provided based on an investigation by the photographic method of 3 elbow joints using cadaveric ...

Recent studies have presented range of motion (ROM) data in degrees for dinosaur forelimb joints, usually via physical manipulation of one individual. Using these data, researchers have inferred limb orientations, postures, gaits, ecological functions and even phylogenetic trends within clades. However, important areas of concern remain unaddressed; for example, how does ROM at a forelimb joint...
