The wrist is one of the most complex synovial joints in the body, composed of eight small irregular bones called the carpals. These bones must work in unison to help with many daily activities that involve the muscles of the forearm and wrist....
Next, a majority of the muscles in our forearms cross over the carpals via tendons and attach to the metacarpals, serving as the primary movers and dynamic stabilizers of the wrist.1These muscles allow for wrist flexion, extension, radial deviation, ulnar deviation, and can assist in forearm ...
The wrist is one of the most complex of all the joints in the body. It’s made up of eight small bones, many connecting ligaments and tendons, muscles, nerves, and blood vessels. Articular cartilage covers the ends of the bones, ...

Wrist braces provide much-needed support, cushioning the wrist and reducing strain on muscles and tendons. By stabilizing the joint, they allow bowlers to continue playing without aggravating existing injuries, acting as a preventative measure against further damage. Types of Wrist Supports Storm ...
Magnetic resonance imaging (MRI) is a noninvasive imaging method that offers remarkable information in assessing both the osseous and the soft tissue structures of the wrist. The ligaments, tendons, nerves, muscles, and cartilage can be resolveddue to the high spatial and contrast resolution of th...
Several of the anterior muscles operating on the wrist and hand pass through the carpal tunnel including 9 extrinsic flexor tendons and the median nerve. Every set of the tendinous slips is surrounded by a synovial sheath, created to lessen friction between the structures....
This is due to the entrapment of the median nerve within the carpal tunnel that results in pain, sensory paresthesia, and muscle weakness. This carpal tunnel is the passageway of the nine tendons and their investing synovial sheaths of the ...
Your hands and wrists are essential tools that allow you to work, play and perform everyday activities. How well the hand and wrist interact depends on the integrity and function of the ligaments, tendons, muscles, joints and bones. Problems in any of these can affect upper extremity function...
Wrist posture impacts the muscle lengths and moment arms of the extrinsic finger muscles that cross the wrist. As a result, the electromyographic (EMG) activity associated with digit movement at different wrist postures must also change. We sought to quantify the posture-dependence of extrinsic fing...
