The hand and wrist are rare sites for tuberculosis (TB) and account for < 1% of all skeletal TB. Though rare, TB of the wrist is a cause of major morbidity. A common feature in the available reports on wrist TB is a delay in diagnosis causing residual stiffness and pain after treatment. Although TB of the wrist has a varied presentation, the majority of lesions respond to conservative treatment...

From a mechanical point of view, the wrist represents the most complex joint in the body, providing a large range of motion in the flexion-extension (FE) and radial-ulnar-deviation (RUD) planes. Anatomically, the wrist could be divided into two carpal rows. Deeper insight into wrist biomechanics is highly desirable, because the complex wrist structure causes a variety of possible injuries and t...

Even when the muscles surrounding a joint are inactive, they still exert a damping effect on joint mobility, because of the passive elastic tension exerted by the stretched muscle fibres and their connective tissue (Clemmesen, 1951). For example, if the forearm muscles are allowed to relax and the forearm is then shaken violently, the hand will swing loosely at the wrist; however, if the experi...

BACKGROUND Posttraumatic ulnar carpal translocation is a very rare condition that is caused either by fracture-dislocation injury or by purely ligamentous injury of the wrist. Its prognosis is poor and development of posttraumatic pancarpal wrist joint osteoarthritis is inevitable, and options for treatment are total wrist fusion or total wrist arthroplasty. METHODS A 24-year-old male sustain...

BACKGROUND To compare the effectiveness of a custom-made leather wrist splint (LS) with a commercially available fabric splint (FS) in adults with chronic wrist pain. METHODS Participants (N = 25, mean age = 54) were randomly assigned to treatment order in a 2-phase crossover trial. Splints were worn for 2 weeks, separated by a one-week washout period. Outcomes were assessed at baseline and a...

The treatment for giant cell tumors of the tendon sheath is surgical therapy, but surgical recurrence rates were reported to be as high as 50% in some cases. Therefore, complete radical excision of the lesion is the treatment of choice. If the tumor originates from the joint, it is important to perform capsulotomy. Here, the authors report the first case of successful treatment of a localized i...

PURPOSE Midcarpal degeneration is well documented after radioscapholunate fusion. This study tested the hypothesis that radioscapholunate fusion alters the kinematic behavior of the remaining lunotriquetral and midcarpal joints, with specific focus on the dart-thrower's motion. METHODS Simulated radioscapholunate fusions were performed on 6 cadaveric wrists in an anatomically neutral posture....

Eleven cases of injury of the superficial radial nerve on the wrist joint, caused by intravenous injection of a needle. Paralysis occurred immediately after injection of a needle into the cephalic vein of the wrist joint, which was immediately recognized by the patients themselves. Six patients who had only sensory disturbance without causalgia were subjected to follow-up observation; 5 patient...

The presence of muscle redundancy and co-activation of agonist-antagonist pairs in vivo makes the optimization of the load distribution between muscles in physiologic joint simulators vital. This optimization is usually achieved by employing different control strategies based on position and/or force feedback. A muscle activated physiologic wrist simulator was developed to test and iteratively ...

BACKGROUND Median nerve neuropathy caused by compression from a tumor in the forearm is rare. Cases with anterior wrist ganglion have high recurrence rates despite surgical treatment. Here, we report the recurrence of an anterior wrist ganglion that originated from the Scaphotrapezial joint due to incomplete resection and that caused median nerve neuropathy in the distal forearm. CASE PRESENT...
