Factors influencing healing

Factors influencing healing
- Displacement and site of fracture
- Blood supply to area
- Immobilization
- Internal fixation devices
- Infection or poor nutrition
- Age
- Smoking
Complication of fracture healing
- Delayed union
  - Fracture healing progresses more slowly than expected. Healing eventually occurs.
- Nonunion
  - Fracture fails to heal despite treatment. No x-ray evidence of callus formation
- Malunion
  - Fracture heals in expected time but in unsatisfactory position, possibly resulting in deformity or dysfunction
- Angulation
- - Fracture heals in abnormal position in relation to midline of structure (type of malunion)
- Pseudoarthrosis
  - Type of nonunion occurring at fracture site in which a false joint is formed with abnormal movement at site.
- Refracture
  - New fracture occurs at original fracture site
- Myositis ossificans
  - Deposition of calcium in muscle tissue at site of significant blunt muscle trauma or repeated muscle injury
