Definition
Osteochondrome is the most common benign bone tumor. In most cases, it originates from the growth plate and forms nodular bone outgrowths of hard bone material (corticalis), which is covered by a cap of hyaline cartilage.
Frequency
Osteochondrome is the most common bone tumor in children. It develops in most cases between the ages of 10 and 20. It is equally distributed over both sexes in the occurrence.
In rare cases there is a familial hereditary form that must be considered separately.
- Wrist spoke
- Shinbone near ankle joint
- Calf bone close to the knee and ankle
- Hand and tarsal bones
- Flat bones (shoulder blade, ilium, rib, skull, sternum) .
- Most frequent localization:thigh and lower leg close to the knee, upper arm close to the elbowThe tumor develops at the end of the long tubular bones. At these sites, there seems to be a false growth in the growth joint with lateral outgrowth of parts of the growth zone.
Therefore the benign tumor is covered with a cartilage cap. In the course of growth, the osteochondrome moves away from the growth joint (see picture above).
