Stress Fractures

QUESTION:  What is a stress fracture, and what are the symptoms that may indicate one is present? How are they treated?

ANSWER: Stress fractures most often are fractures that result from abnormal stresses on normal bone. Studies have shown that when increased loading is applied to bone, its strength does not start to increase until about the second week and will continue to increase over the next two weeks.

Pain is the usual symptom of a stress fracture, and this usually will increase with activity and decrease with rest. Swelling may also be present. Stress fractures must also be distinguished from other overuse injuries, such as tendinitis, ligament sprains and contusions. Plain X-rays may show the fracture in about fifty percent of stress fractures. Special studies, such as bone scans, may be necessary to show the fracture in some cases.

Rest is the treatment for most fractures. Usually some modified exercises can be maintained during recovery. Stress fractures can displace and require more extensive treatment if early symptoms are ignored.
