Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
A broken finger or finger fracture is a common type of bone fracture, affecting a finger. [1] Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger. [2] Although most finger fractures are easy to treat, failing to deal with a fracture appropriately may result in long-term pain and disability ...
The joint closest to the tip is the distal interphalangeal (DIP) joint. The next joint, moving closer to the hand, is the proximal interphalangeal (PIP) joint. The thumb differs by only having two bones and one interphalangeal joint. [10] The injured finger may be examined to determine where the pain is worst. [3]
The joints between these bones are referred to as the proximal interphalangeal joint (PIP, between the proximal and middle phalanx) and the distal interphalangeal joint (DIP, between the middle and distal phalanx). muscles that begin in the forearm send long tendons to the fingers and these tendons attach at different points on these bones ...
Trauma deformities may manifest as reduced joint function due to lack of coordination in phalangeal joints, such as proximal interphalangeal flexion and distal interphalangeal hyperextension in boutonnière deformity. [1] Besides trauma, another reason boutonnière deformity may develop is due to a chronic disease like rheumatoid arthritis. [1]
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs.A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs.
An open fracture may be another reason. Surgery will put the finger in a neutral position and drill a wire through the distal interphalangeal joint (DIP) to the proximal interphalangeal joint (PIP), forcing immobilization.
