One of the most common injuries of the hand is the metacarpal bone. In many cases, immobilizing the patient's joint is sufficient. However, on other occasions, it is necessary for the patient to undergo a surgical intervention.
What are the metacarpal bones of the hand?
The hand is made up of several groups of bones: distal phalanges, middle phalanges, proximal phalanges, metacarpal bones, and carpal bones.
There are five metacarpal bones, one for each finger, this bone is the one that joins the proximal phalanges with the carpal bones. This bone has three parts: head, body, and base.
Types Of Metacarpal Fracture
Metacarpal fractures are classified according to the part of the bone where they are located. If it has occurred in the part of the knuckle, it is called a head metacarpal fracture and if it is located below the knuckle, it is called a subcapital metacarpal fracture. These two types are the most complex.
A fracture at the base of the finger would be a base fracture. A fracture located in the center of the metacarpal bone is called a diaphyseal fracture.
Fifth Metacarpal Fracture:
This fracture occurs in the little finger of the hand, it is the most common of all since it is the one that is usually caused by trauma. That is why it is known as a boxer's fracture.
What types of metacarpal fractures usually require surgery?
Usually, the metacarpal fractures that require hand surgery are:
- Malrotation.
- Intra-articular.
- opened.
- Spiroidal
- Comminuted
- Subcapitals
- Irreducible Fractures
- oblique
