Is there such a thing as bone spurs? Should this term be used to explain pain? This has been a point of contention amongst medical professionals for years. Like many colloquial expressions used in the English language, the term “bone spur” is used “generically” to explain an abnormal bump or growth on a bony surface.
Perhaps the term “bone spur” is easy to understand and less frightening to a patient than advising the patient that they have an abnormal enlargement of bone. Just like the term “cartilage deposit” is used to describe a bony bump, the term bone spur is used so as to not alarm the patient.
In all actuality, the term “bone spur” is used to describe an enlargement or overgrowth of bone, usually associated with a joint or the heel, where the bone has enlarged due to a genetic or biomechanical abnormality. The “bone spur” takes years to develop, and is not noticed by the patient until pain is present. Often the term “bone spur” is used to describe a enlargement of the bottom of the heel, and looks like a “spur” when visualized with an X-ray. This type of spur is actually an elongation of the bottom portion of the heel secondary to stress exerted on the heel due to tightness of the plantar fascia, or arch ligament. It is associated with chronic heel pain, usually noticed after periods of rest or first thing in the morning.
Abnormal enlargement of bone (bone spurs) are usually associated with joint surfaces. As the bone enlarges, restriction of joint motion occurs, and pain will ensue. The enlargement of bone can very often take on the appearance of a spur when visualized with an X-Ray. In these situations, the pain caused is due to the restriction of motion of the joint, not the actual spur. Unfortunately, we use the term to describe the appearance of the problem, not why the problem exists.
“Bone spurs” cannot be dissolved by physical therapy or cortisone injections. The pain associated with spurs is reduced with these treatments. The only way “spurs” can removed is by surgical excision.
