Osteoid Osteomas: Identifying and Managing Bone Tumors The osteoid of bone is a matrix of Type I collagen that is embedded in a glycosaminoglycan gel that contains proteins that bind strongly to calcium.
Osteoid Osteomas: Identifying and Managing Bone Tumors The osteoid of bone is a matrix of Type I collagen that is embedded in a glycosaminoglycan gel that contains proteins that bind strongly to calcium. The osteoid is made by the osteoblast cells. Bone is made up of the combination of osteoid, osteoblasts, osteoclasts, and mineral salts.
An osteoid osteoma consists of an area of abnormal osteoid surrounded by dense sclerotic bone tissue. Rarely are multiple nidus found within one sclerotic margin. These are benign tumors that are typically less than 2cm in size.
They affect men more than women and typically occur in a patient’s 20s. Osteoid osteomas are most commonly found in the metaphyseal and diaphyseal regions of the tibia and femur. However, they can also be found in the spine, hands, pelvis, sacrum, and feet.
Intra-articular osteoid osteomas differ from intra-cortical osteoid osteomas and are recognized as separate entities. They are a benign tumor and do not metastasize or have the capacity to become malignant. They are typically categorized based on their location within bone.
This includes either the cortical portion, subperiosteal, or medullary portion. The most common presentation of an osteoid osteoma is a dull and local pain that increases at night. The area of abnormal osteoid, known as the nidus, is innervated by sensory nerve fibers that produce prostaglandins.
If you are experiencing symptoms that may be related to what are osteoid osteomas?, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
