Metacarpal fractures - paediatric

Although shaft fractures are more common, metacarpal fractures in children are often articular or periarticular.

An intracapsular fracture of the metacarpophalangeal joint carries the additional risk of avascular necrosis. Aspiration of the joint at the time of reduction and treatment may decrease this risk.

Fractures of the base of the thumb metacarpal are often SH III fractures that can be viewed as Bennett fracture equivalents. Most of these fractures will require surgical treatment to reduce and pin the fracture accurately. Poor reduction of the articular surface may lead to posttraumatic degenerative arthritis, although this result is rare.
