What is a metacarpal fracture?
The metacarpal bones are the long slender bones which connect your wrist to your fingers and are roughly at the level of your palm. There is one metacarpal for each finger.
Fractures of the hand are the most common fractures of the human skeleton. Metacarpal fractures account for 18% to 44% of all of hand fractures.
Most fractures are due to either accidental falls or direct blows to another object or individual, with small-finger neck fractures and ring-finger shaft fractures among the most common metacarpal fractures.
As with any hand fracture, the primary goals are to achieve anatomic and stable reduction, bony union, and early mobilisation to minimise disability.
Interesting fact: Metacarpal fractures are often referred to as a ‘boxer’s fracture’ due to its prevalence in boxers or athletes of other sports or activities.
What are the symptoms of metacarpal fracture?
- Swelling
- Pain and tenderness over hand
- Bone or joint that is clearly deformed or broken
- Unsteady breathing or pulse
- Tingling, numbness or paralysis in hand
Imaging:
Imaging- Xray – gold standard metacarpal fracture diagnosis
- CT or MRI for further tissue damage or multiple injuries
Complications of metacarpal fractures
Metacarpal fractures can result in deformities including; malrotation, angulation, and shortening. Complications can also result with a decreased range of motion, infection or nonunion.
Treatment options of metacarpal fracture
Conservative approach – your Action Rehab hand therapist will fabricate a custom thermoplastic splint which will allow for healing and union of the fracture, followed by an array of ranging and stability exercises. The primary goals of treatment are to achieve acceptable alignment, stable reduction, strong bony union, and unrestricted motion.
Non-conservative approach – open reduction or internal fixation (surgery) by an orthopaedic surgeon
