Mal-Union Fracture

USC Orthopaedic Surgery / Conditions / Mal-Union Fracture

A mal-union fracture occurs when a broken bone heals in a misaligned position. This can result in the bone being shorter than it was originally, or displaced and bent out of position.

The misalignment affects the joint by causing pain, joint degeneration, arthritis and instability of the joint. If the mal-union is painful or damaging, surgery may be required.

What are the signs and symptoms of mal-union fracture?

  • Stiffness in the affected area
  • Limited use of the affected area
  • Inability to fully flex the affected joint
