It is an abductor of the little finger [1] at the metacarpophalangeal joint. [6] It is also possible that the muscle contributes to extension of the middle phalanx of the little finger through its connection to finger's extensor mechanism. [5] It plays an important role when the hand is grasping large objects with outspread fingers. [7]
Most hand injuries are minor and can heal without difficulty. However, any time the hand or finger is cut, crushed or the pain is ongoing, it is best to see a physician. Hand injuries when not treated on time can result in long term morbidity. [6] Simple hand injuries do not typically require antibiotics as they do not change the chance of ...
Climber's finger is one of the most common climbing injuries within the sport of rock climbing, accounting for about 30% of finger injuries seen in climbers. [1] It is an overuse injury that usually manifests in a swollen middle or ring finger due to a damaged flexor tendon pulley , normally the A2 or A4 pulley.
Jammed finger is a colloquialism referring to a variety of injuries to the joints of the fingers, resulting from axial loading beyond that which the ligaments can withstand. Common parts of the finger susceptible to this type of injury are ligaments , joints , and bones .
604 injured rock climbers were prospectively evaluated from January 1998 to December 2001, due to the rapid growth of new complex finger trauma in the mid-1980s. Of the most frequent injuries, three out of four were related to the fingers: pulley injuries accounted for 20%, tendovaginitis for 7%, and joint capsular damage for 6.1%. [5]
Trigger finger, also known as stenosing tenosynovitis, is a disorder characterized by catching or locking of the involved finger in full or near full flexion, typically with force. [2] There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease ). [ 3 ]
The MCP joints at the base of the finger responds much better to treatment and are usually able to fully extend after treatment. Due to anatomic differences in the ligaments and extensor tendons at the PIP joints, they may have some residual flexion. Proper patient education is necessary to set realistic treatment expectation.
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
