How do you fix a dislocated metacarpophalangeal joint?
How do you fix a dislocated metacarpophalangeal joint?
Finger MCP joint hyperextension injuries may be treated by gently flexing the proximal phalanx and immobilizing the MCP joint in 30° of flexion for 2-3 weeks. A dorsal extension-block splint protects the healing volar plate while allowing active flexion of the finger.
Can you dislocate MCP joint?
The mechanism of injury of a metacarpophalangeal (MCP) joint dislocation is typically a hyperextension after a fall onto an outstretched hand. MCP joint dislocations can occur with the proximal phalanx dislocating dorsally or volarly, with the dorsal dislocation occurring significantly more often.
What motions are possible at the first metacarpophalangeal MCP joint?
The primary movements of the metacarpophalangeal joints are flexion, extension, abduction, adduction, circumduction and limited rotation.
What are the movements of the metacarpophalangeal joint?
Similar to other joints in the body, the MCP joints are acted upon by muscles to allow for specific joint movements. These movements include flexion, extension, abduction, adduction, and limited circumduction.
What is metacarpophalangeal dislocation?

How do you relocate a thumb joint?
The bones may move back into place on their own or a doctor may gently put the joint back with a quick maneuver called a reduction. In some cases, surgery is needed to repair the joint. To keep the joint from dislocating again, a splint is put on the thumb (the splint might later be changed to a cast).
What type of joint is the 1st metacarpophalangeal joint?
condyloid type synovial joints
Metacarpophalangeal (MCP) joints are condyloid type synovial joints between the metacarpal bones and proximal phalanges of the hands.
What is the 1st MCP joint?
The metacarpophalangeal joint or MP joint, also known as the first knuckle, is the large joint in the hand where the finger bones meet the hand bones. The MCP joint acts as a hinge joint and is vital during gripping and pinching.
Where is the 1st metacarpophalangeal joint?
The 1st CMC (carpometacarpal) joint is a specialized saddle-shaped joint at the base of the thumb. The trapezium carpal bone of the wrist and the first metacarpal bone of the hand form the 1st CMC or thumb basal joint.
What is the first metacarpophalangeal joint?
The metacarpophalangeal joint or MP joint, also known as the first knuckle, is the large joint in the hand where the finger bones meet the hand bones. The MCP joint acts as a hinge joint and is vital during gripping and pinching. When arthritis affects the MP joint, the condition is called MP joint arthritis.
