How many types of joints are in the hand?
Each of the fingers has three joints: metacarpophalangeal joint (MCP) – the joint at the base of the finger. proximal interphalangeal joint (PIP) – the joint in the middle of the finger. distal interphalangeal joint (DIP) – the joint closest to the fingertip.
What type of joint is in the fingers?
The finger joints The joints of the fingers include the metacarpophalangeal joints and the interphalangeal joints. They’re all synovial joints with synovial membranes and fibrous joint capsules.
What type of joint are knuckles?
Metacarpophalangeal Joint
Metacarpophalangeal Joint (MCP): The MP joint is where the hand bone meets the finger bone, referred to as the “knuckle.” These joints are very important, allowing us to bend/flex and spread our fingers.
What are MCP and PIP joints?
The joints involved most frequently are the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints of the hands, the wrists, and small joints of the feet including the metatarsophalangeal (MTP) joints. The shoulders, elbows, knees, and ankles are also affected in many patients.
What type of joint is found in the wrist?
condyloid synovial joint
The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.
What is PIP joint in hand?
The PIP joint is the first joint of the finger and is located between the first two bones of the finger. The PIP joint can bend and extend the finger. It becomes stiff easily after injury and has very limited side to side motion.
What type of joint is metacarpophalangeal joint?
The metacarpophalangeal (MCP) joints are diarthrodial joints where the large convex heads of the distal aspect of the metacarpals articulate with the concave-shaped proximal aspect of each phalange. The articulating surface of each metacarpal head and proximal phalange is composed of hyaline cartilage.
What joints are in the hand and wrist?
Joints of the Wrist and Hand
| Joint | Proximal articulation | Type |
|---|---|---|
| Radiocarpal joint | Radius and articular disc/ concave | Ellipsoid |
| Midcarpal joint | Scaphoid. Lunate, Triquetrum | Gliding |
| Carpometacarpal joint (thumb) | trapezium | Saddle |
| Carpometacarpal joint (fingers) | trapezoid, trapezium capitate capitate, hamate hamate | Ellipsoidal |
What does MP joint stand for?
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.
What is DIP and PIP joints?
“proximal interphalangeal joints” (PIJ or PIP), those between the first (also called proximal) and second (intermediate) phalanges. “distal interphalangeal joints” (DIJ or DIP), those between the second (intermediate) and third (distal) phalanges.
