Bone Spur Finger
Most bone spurs on fingers are caused by osteoarthritis. This disease affects cartilage,
the tissue that cushions and protects the ends of bones in a joint. With osteoarthritis,
the cartilage starts to wear away over time. In extreme cases, the cartilage can
completely wear away, leaving nothing to protect the bones in a joint, causing
bone-on-bone contact. Bones may also bulge, or stick out at the end of a joint, called a
bone spur.
Bone spurs can also be caused by an injury to a finger joint. In the process of trying
to heal the injury to the bone cause by the trauma to the finger joint the body sometimes
over compensates and in the process causes calcium build up which forms into a bone spur. |
