Torque-angle relations at the elbow and ankle joints of relaxed normal controls and patients with hemiparetic stroke were compared. Low velocity flexion/hold/extension angular perturbations were applied to the joint under examination. The resulting torque-angle profiles described a hysteresis loop with similar slopes during the extension and flexion stages but separated by a vertical torque off...

The elbow, the middle joint of the upper limb, enables the hand to be placed at various distances from the body. The articular, muscular and neuromotor complexity of the elbow is such that it is often prone to stiffness, especially if immobilized for long periods of time. Therefore, mobilization of the posttraumatic elbow must be started early. In the presence of lesions to the ligamentous stru...

Proximal radial fractures typically occur after a fall on the outstretched hand. Elbow trauma is usually followed by post-traumatic elbow stiffness, which has been recognized as major cause of functional impairment. A stiff restricts patient’s ability to position hand in space required, for desired use upper extremities during activity daily living. The goal rehabilitation, stiffness restore ar...

Severe posttraumatic elbow stiffness represents a significant invalidity. Between 1990 and 2005 two surgeons performed open elbow arthrolysis in 30 adult patients (6 women, 24 men, mean age 30.8 years). All cases resulted from severe initial trauma, which had occurred on average 15.5 months previously. Four patients had extrinsic and 18 had mixed contractures; 13 had heterotopic ossifications. ...

The stiffness of activated muscles may stabilize a loaded joint by preventing perturbations from causing large displacements and injuring the joint. Here the elbow muscle recruitment patterns were compared with the forearm loaded vertically (a potentially unstable inverted pendulum configuration) and with horizontal loading. Eighteen healthy subjects were studied with the forearm vertical and s...

This study reports our experience with total elbow replacement for fused elbows. Between 1982 and 2004, 13 patients with spontaneously ankylosed elbows were treated with a linked semi-constrained non-custom total elbow implant. The mean age at operation was 54 years (24 to 80). The stiffness was a result of trauma in ten elbows, juvenile rheumatoid arthritis in one, and rheumatoid arthritis in ...

Elbow stiffness is a common problem after joint trauma, causing functional impairment of the upper limb. The severity of the dysfunction depends on the nature of the initial trauma and the treatment used. Appropriate clinical evaluation and complementary examinations are essential for therapeutic planning. Several surgical techniques are now available and the recommendation must be made in acco...

UNLABELLED To evaluate patients undergoing arthroscopic release of a stiff elbow, with discussion of the technique, possible difficulties and risks. METHODS Twenty-four elbow arthroscopy procedures were performed. All the patients were evaluated using goniometry before the operation and six months afterwards and were rated using the Mayo elbow performance score (MEPS). RESULTS Fifteen men a...

Acute and chronic disorders of the elbow are frequently observed in both recreational and professional athletes, particularly athletes who participate in sports that involve throwing. Although clinicians most frequently evaluate athletes in throwing-related sports who have elbow pathology related to overuse injuries, including ulnar collateral ligament insuffi ciency, valgus extension overload ...
