Skeletal limb abnormalities is a very broad descriptive term. There are a variety of possible abnormalities of the arms or legs (limbs) that can be caused by underlying defects in the skeletal structure.

Skeletal limb abnormalities may result from:

An adamantinoma is a slow growing cancerous bone tumor that is most often found in the shin bone (tibia) or the jaw bone (mandible). Sometimes, these tumors might be found in the forearm, hands or feet. It is a rare tumor, occurring primarily in males between the ages of 10-30, usually after skeletal maturity is reached.
In about 20 percent of cases, adamantinoma cancer cells spread to other parts of the body (metastasize), usually to the lungs or nearby lymph nodes.

Bone: Your body has 206 bones, that serve multiple different functions:
Definition
The number of patients who have bone and mineral disorders has increased in last period of time. This increase is a consequence of multiple factors including: the longer life span of our population, the increasing use of drugs detrimental to bone and kidney, and the availability of new technologies such as bone densitometry, which have made earlier diagnosis possible.
Mineral metabolism disorders are marked by abnormal levels of minerals — either too much or too little — in the blood.
Rickets is the softening and weakening of bones in children, usually because of an extreme and prolonged vitamin D deficiency.
Vitamin D is essential in promoting absorption of calcium and phosphorus from the gastrointestinal tract, which children need to build strong bones. A deficiency of vitamin D makes it difficult to maintain proper calcium and phosphorus levels in your bones. (more…)
A hereditary bone disorder
Osteopetrosis is a congenital disorder (a person is born with it) in which the bones are dense, brittle and break easily.
Who is affected
Deppending of the form of osteopetrosia, both children and adults can be affected. It is difficult to estimate how often the different forms of osteopetrosis occur worldwide. (more…)
Osteoarthritis is a type of arthritis that is caused by the breakdown and eventual loss of the cartilage of one or more joints. Cartilage is a protein substance that serves as a “cushion” between the bones of the joints. Osteoarthritis is also known as degenerative arthritis.
Osteoarthritis commonly affects the hands, feet, spine, and large weight-bearing joints, such as the hips and knees. Most cases of osteoarthritis have no known cause and are referred to as primary osteoarthritis.
