exostosis

[‚ek·sə′tō·səs]
(medicine)
A benign cartilage-capped protuberance from the surface of long bones but also seen on flat bones, caused by chronic irritation as from infection, trauma, or osteoarthritis.

Exostosis

 

a benign bony or bony-cartilaginous growth on the surface of a bone in the form of a linear or round mass. Exostoses develop mainly in males during childhood and adolescence, on the femur, tibia, humerus, and other bones. They cease to enlarge when bone growth ends. They usually do not cause complaints. However, fairly large exostoses compress muscles and nerve trunks, causing pain and hampering movement. The principal means of diagnosing exostoses is by X ray.

Exostoses are removed surgically if symptoms are pronounced or if the exostoses suddenly begin to grow rapidly in adults. Individuals suffering from exostoses are kept under clinical observation.
