What is the meaning of MCP joint?
MCP Joint Arthritis. Hand bones are called metacarpals. The finger bones are called phalanges. The metacarpophalangeal joint (MCP joint), or knuckle, is where the finger bones meet the hand bones. At the MCP joint, the fingers can move in multiple directions.
How many metacarpophalangeal joints are there?
Metacarpophalangeal joint (Articulationes metacarpophalangeae) The metacarpophalangeal joints (MCP) are a collection of condyloid joints that connect the metacarpus, or palm of the hand, to the fingers. There are five separate metacarpophalangeal joints that connect each metacarpal bone to the corresponding proximal phalanx of each finger.
What are the common problems at the MCP joint?
Common problems at the MCP joint includes arthritis and collateral ligament injuries. The small finger CMC joint has the most motion of any finger joint, with the exception of the thumb. This makes the hand more flexible. This permits the hand to change its shape and adapt to grasping objects of different size and shape.
What is the function of the MP joint?
The MP joint is where the hand bone, called the metacarpal, meets the finger bones, called the phalanges. A single finger bone is called a phalanx. MP joints are important for both power grip and pinch activities; they are where the fingers move in relation to the hand.

How many MCP are there?
There are five separate metacarpophalangeal joints that connect each metacarpal bone to the corresponding proximal phalanx of each finger. Each metacarpophalangeal joint is formed by the convex heads of the metacarpal bones which are received by the concave bases of the proximal phalanges.

Understanding Metatarsophalangeal (MTP) Joint Disorders - Verywell Health
Nonsurgical Strategies . Most MTP joint-related problems are managed nonsurgically. For example, in the case of a bunion (a common MTP problem), a healthcare provider will often recommend that the person wear proper shoes, even custom orthotics (special shoe inserts made for your feet). For bunions, a shoe with a wide toe box, and one that is soft and stretchy can be helpful.
Metacarpophalangeal joint - Wikipedia
The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cavities on the proximal ends of the proximal phalanges. Being condyloid, they allow the movements of flexion, extension, abduction, adduction and ...

Why do my fingers move in different directions?
At the MCP joint, the fingers can move in multiple directions. They can bend, straighten, spread apart and move together. MCP joints are important for both pinching and gripping. MCP joint arthritis is most common in the thumb and index fingers due to the stress of pinching.

What is the distal interphalangeal joint?
Distal Interphalangeal Joint (DIP)#N#The DIP joint in the finger is located at the tip of the finger, just before the finger nail starts. Common problems at this joint include Mallet Finger, Jersey Finger, arthritis, mucous cysts, and fractures. The index finger is more likely to develop arthritis from the pinch force that occurs throughout one’s life.#N#Proximal Interphalangeal Joint (PIP Joint)#N#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. Common injuries include sprains, fractures, dislocations, arthritis, and extensor tendon ruptures (leads to Boutonnière deformity ), and hyperextension (Swan neck).#N#Metacarpophalangeal Joint (MCP joint)#N#The MP joint is where the hand bone called the metacarpal meets the finger bones called the phalanges. A single hand bone is called a phalanx. MP joints are important for both power grip and pinch activities; they are where the fingers move with respect to the hand. The MP joints allows you to bend and flex your fingers, spread your fingers, and bring the fingers together. You can spread your fingers more more easily when they are straightened rather than bent because the collateral ligaments are loose when the finger is extended. Common problems at the MCP joint include arthritis and collateral ligament injuries.#N#Carpometacarpal Joint (CMC Joint)#N#The index CMC joint has little motion; this provides a more rigid and stable radial column to the hand. Injuries and problems with this joint are uncommon. Occasionally, joint pain can be caused by a CMC boss.

Cartilage is a smooth surface that allows for gliding. When cartilage is healthy, there is a cushioning effect of the cartilage that absorbs and evens out the forces across the joint. Our joints typically have a capsule of tough, but flexible, fibrous tissue that helps hold the joints together and an inner lining of synovium.
What is the function of the palmar ligament?
The main function of this ligament is to prevent hyperextension of the MCP joint.
What is the capsule of a joint?
The joint is enveloped by a loose fibrous capsule, attached close to the margins of articular facets. On its medial and lateral sides, the joint capsule is thicker and strengthened by collateral metacarpophalangeal ligaments. A palmar metacarpophalangeal ligament mainly replaces the capsule on its anterior aspect, while the posterior capsule receives fibres from the tendons of the long extensors of the forearm (namely extensor pollicis longus, extensor indicis, extensor digitorum and extensor digiti minimi) .
