Fingers with this kind of irregularity will bend at the middle joint.

This permits the hand to change its shape and adapt to grasping objects of different size and shape. Injuries and problems with this joint are uncommon. The large number of bones in the hand and wrist makes for a large number of joints, too.
The PIP joint can bend and extend the finger.

There is an articular disc of fibrocartilage within the joint.

A posterior (back) SC joint dislocation can be a serious injury and puts vital structures at risk such as the heart, aorta, superior vena cava, esophagus, and trachea. The IP joint in thumb is located at the tip of the finger just before the fingernail starts. The joints in our hands are made up of cartilage surfaces that cap the bones. Injuries and problems with this joint are uncommon. The tough fibrous tissue is often what is injured when you have a sprain of a joint.When discussing hand joints, we refer to the palmar or volar surface (the palm side), the dorsal surface (the back of the hand), the radial side (toward the thumb), and the ulnar side (toward the little finger). Nerves send signals from the brain to the muscles (motor nerves) causing it to contract or from receptors in the fingers to the brain (sensory nerves) to enable the different sensations. When cartilage is healthy, there is a cushioning effect of the cartilage that absorbs and evens out the forces across the joint.

The ulnohumeral joint is formed by the coming together of the humerus and ulna bones. The skin of the fingers are supplied by different nerves as follows : Please note that any information or feedback on this website is not intended to replace a consultation with a health care professional and will not constitute a medical diagnosis. The acromium is part of the scapula (shoulder blade) and the clavicle (also called the collarbone). It’s a synovial joint that allows for a lot of movement; it’s formed where the head of the ulna articulates with the ulnar notch of the radius. The radial and ulnar collateral ligaments are important to provide stability of the fingertip during pinching.Metacarpophalangeal Joint (MP)The MP joint is where the hand bone, called the metacarpal, meets the finger bones, called the phalanges. The shoulder has a great deal of motion including bending and straightening, moving away from the side of the body, moving toward the body, and circumduction (a spinning type of motion). There are two ways in which the muscles controlling the fingers can be classified. The radiocarpal joint is a synovial joint that’s also found in the wrist. They’re all synovial joints with synovial membranes and fibrous joint capsules. Each finger (digits two through five) has one proximal interphalangeal joint and one distal interphalangeal joint. The MP joints allows you to bend and flex your fingers, spread your fingers, and bring the fingers together. Metacarpophalangeal joints: Connecting the proximal phalanges to the metacarpals are condyloid joints with strong palmar and collateral ligaments that allow for movement in different directions (flexion, extension, abduction, adduction, circumduction). The joints in our hands are made up of cartilage surfaces that cap the bones.

Surgical treatment for arthritis of the joint often includes removal of the trapezium or resurfacing of the joint.

The thumb interphalangeal (IP) joint is similar to the distal interphalangeal (DIP) joint in the fingers.

The motion of this joint permits the clavicle to move up and down and front to back. The first is by location. The AC joint is where the scapula and clavicle come together. When the muscle contracts, the tendon is pulled and the finger moves at the respective joint. There is only one metacarpophalangeal joint (MCP joint) which lies between the proximal phalanx and metacarpal (hand bone). It becomes stiff easily after injury. MP joints are important for both power grip and pinch activities; they are where the fingers move with respect to the hand. The human finger is mainly a bony structure with multiple joints giving it strength and flexibility. A broken wrist (fracture) that collapses and tilts can cause the ulna to be longer than the radius, which causes extra stress and pain, even after the fracture heals and stops hurtig. This joint is involved with raising and lowering the arm and moving the arm forward and backward. It has a fibrous joint capsule that’s attached to that distal end of the radius and the ulna and to the carpal bones. Types of Finger Arthritis.

Common problems at this joint include Mallet Finger, Jersey Finger, arthritis, mucous cysts, and fractures. CMC bossing is a problem that does not typically occur at this joint.

The finger bones are known as phalanges (singular ~ phalanx).

These joints don’t have much movement, just a small amount of gliding between the bones. The joints of the fingers include the metacarpophalangeal joints and the interphalangeal joints. Common problems with this joint include stiffness, dislocation, labral tears, bursitis, rotator cuff tears, long head of biceps tendonitis or tears, subacromial impingement, proximal humeral fractures, and arthritis. The distal radioulnar joint allows you to flip-flop each hand at the wrist. Humans have five fingers on each hand and a significant feature in humans is the opposable thumb. The carpometacarpal joints are synovial joints between the distal carpal bones and the metacarpals, and the intermetacarpal joints are between the metacarpals. The ulnar collateral ligament of the thumb MP joint is important to stabilize the thumb during most pinch activities and is commonly injured.Carpometacarpal Joint (CMC)The thumb CMC joint has the most freedom of motion.
