Injuries to metacarpal bones

Causes Diagnosis Management
  • Injury to metacarpal bones can be caused by blow on dorsum of hand
  • Punching
  • May affect one or more bones.
  • May be shaft or neck fracture
  • Fractures of metacarpal I and V are not very stable
  • Fractures of neck of metacarpal V are the commonest and the most stable.
 
  • Inspection
  • X-ray
  • Reduction
  • Immobilize the finger with its neighbor if it is a single shaft fracture. Neck fractures occur usually with some angulation. Transverse fractures may be slow to unite.
  • To avoid dropped knuckle complication which follows angulation of the metacarpal fracture, place in a Colles' fracture plaster.
