Abstract:
A series of 113 osteochondromas were treated in our institution with a long-term follow-up. A retrospective study of the cases of solitary osteochondroma diagnosed and treated in our center from 1970 to 2002 was done. A diagnosis for clinical findings in 73% of the patients was made. The most frequent location was the distal femur. Six patients had a recurrence and in two patients the lesions became malignant and chondrosarcoma developed. Relapse of the exostosis is rare, occurring in an estimated 2% of the resections. The growth of an osteochondroma and/or the presence of pain in older patients suggest possible malignancy.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
