Background:
Osteochondromas are frequently reported to be the most common benign tumor of bone. However, there is not definitive data on their prevalence rate as they are often clinically silent, with previous studies estimating 1-3%.
Methods:
We examined a large osteologic collection of 2954 skeletons to identify likely osteochondromas. One author examined all bones excluding the skull in each skeleton for atypical cortical projections. These candidates were then evaluated by an orthopedic resident and then a fellowship trained pediatric orthopedic surgeon for final inclusion using strict criteria.
Results:
13 cases of osteochondroma were identified from 2954 skeletons to yield a prevalence of 0.44% (95% confidence interval 0.20% - 0.68%) in the study population. All were located on long bones: three in the humerus, six in the femur and four in the tibia.
Conclusions:
We found a prevalence of 0.44% for osteochondromas, which is approximately half the lowest value reported in previous literature.

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...

01:17Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
