How do you reduce a metacarpal neck fracture?
Most closed simple metacarpal neck fractures can be managed conservatively by flexing the digit at the metacarpophalangeal and proximal interphalangeal joints and applying a dorsally directed force along the plane of the first phalanx. Stable fractures can then be splinted externally.
What is 5th metacarpal neck fracture?
A closed (the overlying skin remains intact) fifth metacarpal neck fracture occurs when the bone is broken just below the knuckle of the little finger. These account for approximately one in five of all hand fractures.
What is the head of the metacarpal?
The heads of the metacarpals are bulbous and “cam” shaped, thereby permitting adduction, abduction, flexion, extension and passive rotation of the fingers. The collateral ligaments join the metacarpal to the proximal phalanx and are taut in flexion, while having some laxity in extension (figure 1).

What is the most common metacarpal fracture?
Fracture of the fifth metacarpal neck is the most common metacarpal fracture. It often occurs a result of a punch injury and is thus commonly referred to as a “boxer’s fracture.” These fractures are relatively easy to reduce, and a certain amount of angulation is permissible before splinting.

When should a metacarpal fracture be reduced?
Metacarpal neck fractures Most surgeons agree that no more than 10° of angulation in the second and third metacarpals should be accepted without reduction. The ulnar 2 metacarpals are more mobile at the CMC joint and can function well with greater amounts of angulation of the metacarpal shaft or neck.
Where is the head of the metacarpal?
Metacarpal Head: The rounded distal end (the upper end on the side of the fingers). The area right below the head is referred to as the neck of a metacarpal. Metacarpal Body/Shaft: The long part between the head and the base; the metacarpal shaft has a concave palmar aspect, and sides.
Is head of metacarpal base?
Each metacarpal bone consists of a body or shaft, and two extremities: the head at the distal or digital end (near the fingers), and the base at the proximal or carpal end (close to the wrist).
How do you know if your metacarpal is fractured?
This can be assessed by asking the patient to make a fist. When they do so, the fingers should all line up properly and be parallel. If the finger corresponding to the fractured metacarpal does not line up properly with the surrounding fingers, then the fracture ends are most likely rotated.
How long does it take for a broken metacarpal bone to heal?
Most metacarpal fractures fully heal in about 10 weeks, therefore it’s normal to have some stiffness and swelling for that length of time. Metacarpal fractures are generally described by the location of the fracture. Fractures in the center of the bone are called metacarpal shaft fractures.
What is the prognosis of metacarpal fractures?
The prognosis for metacarpal fractures is generally excellent. The fingers become stiff very fast after being immobilized – whether they are injured or not. Most hand surgeons try to limit the time that the fingers are immobilized and begin physical therapy as soon as possible to prevent stiffness from occurring.
What carpal bone is most often fractured?
Of the carpal elements, bones in the proximal row are the most frequently fractured. Scaphoid fracture is by far the most common carpal bone fracture, representing 70% of fractures in the carpal group and 10% of all hand fractures.Triquetral fracture is the second most common, accounting for 14% of wrist injuries.
What causes neck bone pain?
The most common cause of neck pain occurs when one of these soft tissues becomes strained or sprained from overuse or overextension. This type of injury typically heals within a week or two.
