Not all broken bones heal at the same rate and some may develop into a
non-union. Some fractures may be less likely to heal because of the type of fracture, such as an open fracture (also known as a compound fracture, when a broken bone penetrates the skin), or the
fracture’s location. Others may heal more slowly because the patient does not follow his or her surgeon’s advice.
Still other fractures may heal slowly because of a patient’s lifestyle or medical conditions. These factors which inhibit or delay healing, some controllable and some not, are often referred to as risk factors.
Risk factors that can delay bone healing include:
- Smoking or tobacco use
- Diabetes
- Obesity
- Advanced age
- Osteoporosis
- Certain anti-inflammatory medications such as aspirin and ibuprofen (NSAIDS), steroids, hormones and anticoagulants
- Nutritional deficiency
- Anemia
- Vascular insufficiency
