Definition of metacarpal (Entry 2 of 2) : a bone of the part of the hand or forefoot between the carpus and the phalanges that typically contains five more or less elongated bones when all the digits are present.

How do you fix a broken metacarpal?

Treatment. Treatment of a metacarpal fracture can usually be accomplished with the use of a cast. A cast is usually worn for three to six weeks, followed by gentle motion exercises. 2 Occasionally, if stiffness becomes a problem after cast treatment, a hand therapist will be recommended to work with you.

How long do metacarpals take to heal?

Most of the healing happens between three to six weeks but can take several months for your full symptoms to settle completely. In addition, once the fracture has healed you may have a permanent 'bump' where the bone was fractured.

Which metacarpal bone is the shortest?

The metacarpal bone 1 is the most lateral, thickest and shortest metacarpal bone. It is directed laterally, with its long axis being medially rotated for the 90° in comparison to the other metacarpals. Due to this axial rotation, the sides of the bone are rotated so that its anterior surface faces medially towards the palm, the ulnar border faces posteriorly, while the radial faces anteriorly.

Why does my metacarpophalangeal joint hurt?

The metacarpophalangeal joint pain is a common occurrence, due to the fact that the respective joints are used quite a lot and, thus, present a higher risk for the common wear and tear. The aging process, as well as a number of medical conditions can favor the appearance of MCP joint pain.

What happens if cartilage is not properly protected?

If the cartilage is no longer intact, the joint is not properly protected and lubricated. As the bones will grind on one another, pain and inflammation will appear as common symptoms. Once again, depending on the severity of the condition, the patient might be prevented from fully functioning.

Why does my MCP joint hurt?

Another common cause of MCP joint pain is osteoarthritis, which is an inflammatory condition as well. This is often favored by the repetitive usage of the MCP joints, with the breakdown of cartilage being a common occurrence. If the cartilage is no longer intact, the joint is not properly protected and lubricated.

What causes MCP pain?

Physical Injuries. Physical injuries, especially fractures, can cause MCP joint pain, requiring immediate intervention. Depending on the severity of the fracture, one might require casting or surgical correction. Open fractures are even more severe, presenting a high risk of infection.
