There is an increased risk of interosseous intercarpal injury if the ulnar variance (the difference in height between the distal end of the ulna and the distal end of the radius) is more than 2mm and there is fracture into the wrist joint. [5] Triangular fibrocartilage complex (TFCC) injury occurs in 39% to 82% of cases.
A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion.. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movem
A soft tissue injury is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one-off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function. [1]
Wrist mobility is often restricted due to inflammation of the forearm muscles as they contract and tighten due to injury. [2] Most wrist dislocations occur between the capitate and the lunate. [17] [18] Carpal fractures are caused by falling on an outstretched hand the wrist is hyper-extended in ulnar deviation with a component of rotation. [18]
Fracture with a dorsal tilt. Dorsal is left, and volar is right in the image. There are a number of ways to classify distal radius fractures.Classifications systems are devised to describe patterns of injury which will behave in predictable ways, to distinguish between conditions which have different outcomes or which need different treatments.
In cases of minor wrist injuries and sprains, it's often recommended that the patient wear a wrist brace throughout the healing process to provide support and protection from further injury.
The equivalent injury to a ligament is a sprain. [1] Generally, the muscle or tendon overstretches and partially tears, under more physical stress than it can withstand, often from a sudden increase in duration, intensity, or frequency of an activity.
Dorsal rotation injury, such as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries. Injury may also occur from a distraction force applied to the volar forearm or wrist. Finally, tears of the TFCC are frequently found by patients with distal radius fractures. [7]
