C6 quadriplegic patients lose the ability to use their triceps, but the arm flexors remain intact. However, they are still able to extend the elbow. A previous kinematics study showed that their pointing movements were very similar to those of healthy subjects. We make the hypothesis that the triceps is more likely to be used to ensure elbow stiffness than to provide an active elbow extensor to...

We used a robotic device to test the idea that impedance control involves a process of learning or adaptation that is acquired over time and permits the voluntary control of the pattern of stiffness at the hand. The tests were conducted in statics. Subjects were trained over the course of 3 successive days to resist the effects of one of three different kinds of mechanical loads: single axis lo...

BACKGROUND Complex elbow injuries with associated nerve, muscle, or joint injury commonly develop post-inury stiffness. In order to preserve function, joint congruency, elbow stability and durable wound coverage must be achieved in a timely manner. METHODS A retrospective review of patients who underwent orthopaedic fixation followed by free anterolateral thigh (ALT) flap soft tissue coverage...

PURPOSE. To evaluate outcome of open reduction and Kirschner wire fixation with triceps lengthening for neglected elbow dislocations. METHODS. Records of 6 women and 14 men aged 7 to 60 (mean, 20) years who underwent open reduction and Kirschner wire fixation with triceps lengthening for neglected elbow dislocations were reviewed. The dislocations were posterolateral (n=11), posterior (n=4), an...

Continuous passive motion (CPM) is an orthopedic treatment or a physiotherapy and is tried to apply after surgery for the injured radial collateral ligament (RCL) in the elbow joint. After the surgery, the reaction force at hand of the patient increases due to an increase of the joint stiffness and may be excessively large. For this, it is effective to reduce the excessive reaction force by con...

Coverage of the olecranon area is always challenging in traumatology. Because of the superficial situation of the bone, the absence of muscle, the thinness of the skin and the subcutaneous tissue locally, skin defects are not uncommon and can lead to exposure of hardware or prostheses. We report an original surgical technique using a musculocutaneous flap from the flexor carpi ulnaris (FCU) wit...

We report a case of a 37-year-old woman who sustained a bilateral Hahn-Steinthal type fracture of her capitellum humeri. Open reduction and internal fixation, using extra-articular insertion of Herbert screws, were performed. Both elbows were immobilised for 3 weeks postoperatively. Radiographic signs of union were present at week 8. Within the observation period of 18 months, no signs of avasc...

The elbow joint is prone to stiffness and adhesion after trauma or surgery. High-energy easily led loss of mobility the joint. Mild can also cause in In order investigate pathogenesis joint, a feedback-type control system based on network proposed this paper. simulation results show that it has significant differences bioelectrical impedance patients with trauma, new method realizes strategy co...

We performed a lateral approach for the release of post-traumatic stiffness of the elbow in 22 patients using a modified technique designed to spare the lateral ligaments. They were reviewed after a mean interval of 26 months. The total humeroulnar joint movement had increased from a mean of 74 degrees to 129 degrees and forearm rotation from a mean of 135 degrees to 159 degrees. Both pain and ...

Spasticity is common following stroke; however, high subject variability and unreliable measurement techniques limit research and treatment advances. Our objective was to investigate the use of shear wave elastography (SWE) to characterize the spastic reflex in the biceps brachii during passive elbow extension in an individual with spasticity. The patient was a 42-year-old right-hand-dominant m...
