BACKGROUND To investigate the performance of conventional radiography (CR) for the detection of bone erosions of wrist in rheumatoid arthritis (RA) using multidetector computed tomography (CT) as the reference method and to evaluate the validity of a computer-assisted manual segmentation (outlining) technique to quantify erosion volume on CT scans. METHODS Twenty five RA patients and six cont...

BACKGROUND Management of the end-stage rheumatoid wrist is controversial. The most common treatment is total wrist fusion. Total wrist arthroplasty offers a motion-preserving alternative. Comparison of outcomes for total wrist arthroplasty and total wrist fusion is necessary for evidence-based decision making. The purpose of this systematic review was to scientifically evaluate the existing lit...

Advanced non-inflammatory arthritis of the wrist can lead to significant disability. Traditionally, the treatment for arthritis of the wrist which does not respond to either anti-inflammatory medication, splintage, steroid injections and time, would be a total wrist fusion. However, wrist fusion substantially diminishes function1 and is usually avoidable. Two facts should prompt the surgeon to ...

BACKGROUND AND PURPOSE Splints are commonly applied to the wrist and hand to prevent and treat contracture after stroke. However, there have been few randomized trials of this intervention. We sought to determine whether wearing a hand splint, which positions the wrist in either a neutral or an extended position, reduces wrist contracture in adults with hemiplegia after stroke. METHODS Sixty-...

A Filipino female teenager with gross deformity of her right wrist, came as an outpatient for radiographic evaluation nonspecific pain and numbness after prolonged repetitive, active wrist movements like writing clapping, are noted no history trauma, infection, or surgical intervention the aforementioned wrist.

Because wrist rotation dynamics are dominated by stiffness (Charles SK, Hogan N. J Biomech 44: 614-621, 2011), understanding how humans plan and execute coordinated wrist rotations requires knowledge of the stiffness characteristics of the wrist joint. In the past, the passive stiffness of the wrist joint has been measured in 1 degree of freedom (DOF). Although these 1-DOF measurements inform u...

Wrist stiffness has been shown to have a greater effect on wrist dynamics than inertia and damping for all but the fastest wrist rotations [1]. Therefore, making coordinated wrist rotations requires that humans predict and compensate for the effects of wrist stiffness. Because wrist stiffness is anisotropic (with greater stiffness in radial-ulnar deviation than flexion-extension), some movement...

PURPOSE This study examined the kinematic differences between a body-powered prosthesis and a biomechatronics prosthesis as a transradial amputee performed activities that involve flexion/extension and supination/pronation of the wrist. METHOD The subject's wrist movements were calculated and compared as he completed a wrist range of motion test involving simulated flexion/extension and supin...

Distraction arthroplasty of the ankle, elbow, and hip has become widely accepted and used within the orthopaedic community with excellent initial results which appear sustained. To date it has not been applied to the wrist in the same manner. A novel technique, drawn upon past success of articulated ankle distraction and static wrist distraction, was devised and evaluated by application of arti...

Diagnosis of upper extremity injuries depends on knowledge of basic anatomy and biomechanics of the hand and wrist. The wrist is composed of two rows of carpal bones. Flexor and extensor tendons cross the wrist to allow function of the hand and digits. The ulnar, median, and radial nerves provide innervation of the hand and wrist. A systematic primary and secondary examination of the hand and w...
