In most cases, osteoid osteomas will go away without treatment, although this can take several years. Using over-the-counter pain medications and anti-inflammatory drugs can help bring relief. This type of medication may not work for long, so it may be necessary to try several anti-inflammatory medications.
What happens when osteoblasts break down old bone?
In bones, osteoblasts that create new bone multiply quickly, while osteoclasts that break old bone down, are not. The osteoclast becomes part of the osteoma, and as it hardens into a tumor, pressure on the bone increases, causing pain.

Most osteoid osteomas occur in long tubular bones of the limbs (especially the proximal femur), but any bone may be involved. Furthermore, osteoid osteomas are usually cortical lesions but they can occur anywhere within the bone including medullary, subperiosteal (most commonly in the talus), and intracapsular 2.
What age group is osteoid osteomas?
Epidemiology. Osteoid osteomas are usually found in children, adolescents, and young adults, between the ages of 10 and 35 years 2 . They account for ~10% of all benign bone lesions and there is a male predilection (M:F 2-4:1) 2.
What are the three concentric parts of osteoid osteoma?
An osteoid osteoma is composed of three concentric parts 1: The nidus releases prostaglandins (via the enzymes cyclo-oxygenase-1 and cyclo-oxygenase-2) which in turn result in pain 2.

What is the name of the benign bone forming tumor that typically occurs in children?
Osteoid osteoma. Osteoid osteomas are benign bone-forming tumors that typically occur in children (particularly adolescents). They have a characteristic lucent nidus less than 1.5 or 2 cm and surrounding osteosclerotic reaction, which classically causes night pain that is relieved by the use of salicylate analgesia, e.g. aspirin.
Where are osteoid osteomas found?
Osteoid osteomas are most commonly found in the metaphyseal and diaphyseal regions of the tibia and femur (2). However, they can also be found in the spine, hands, pelvis, sacrum, and feet (2). Intra-articular osteoid osteomas differ from intra-cortical osteoid osteomas and are recognized as separate entities (11). They are a benign tumor and do not metastasize or have the capacity to become malignant (5). They are typically categorized based on their location within bone (11). This includes either the cortical portion, subperiosteal, or medullary portion (11).
What is the most common presentation of osteoid osteoma?
The most common presentation of an osteoid osteoma is a dull and local pain that increases at night (4). The area of abnormal osteoid, known as the nidus, is innervated by sensory nerve fibers that produce prostaglandins (2). Levels of prostaglandins as high as 100 to 1000 times normal have been documented within the nidus of an osteoid osteoma (7). In a survey of patients with hip osteoid osteomas, they found that 90% of the affected population had pain at nighttime and 88% felt that the pain was relieved with NSAIDs (2).
How to treat osteoid osteomas?
Currently, the gold standard for symptomatic osteoid osteomas is thermal radiofrequency ablation under CT guidance (3) . The procedure is performed under a general anesthetic (10). Under CT guidance, a drill bit is inserted into the cortex of the bone (10). Once within the nidus, a radiofrequency probe is inserted into the nidus and heated to 90 degrees Celsius for 4 minutes (10). Research finds that the procedure is typically successful in 90% of the cases (3). In a study done by Rosenthal in the Journal of Bone & Joint Surgery, there was no difference in the rate of recurrence when comparing open excision to radiofrequency ablation (9).
What is the osteoid of bone?
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 (1). The osteoid is made by the osteoblast cells (1). Bone is made up of the combination of osteoid, osteoblasts, osteoclasts, and mineral salts (1).
Can a CT scan show osteoid osteomas?
First line imaging for osteoid osteomas is a plain radiograph (5). The nidus is seen as an oval radiolucency and is surrounded by bony sclerosis (5). When evaluating, second line imaging CT scans have been found to be more accurate in diagnosing these tumors than MRIs (5). In a study comparing the two modalities, CT scans identified the tumor in 67% of the cases and MRI only identified them in 3% of the cases (6). However, due to the small size of the osteoid osteomas, 1mm slices on a CT would be required and this can lead to large radiation doses for the patient (10). The small size of the tumors is also the reason why an MRI may miss the nidus of the tumor (10). Frequently an MRI will only identify an area of non-specific edema within bone, which can be misinterpreted as a stress fracture (10).
Can osteoid osteoma cause swelling in knee?
Physical exam findings can sometimes reveal a knee effusion due to the osteoid osteoma’s proximity to the joint (5). There can also be local bony tenderness and soft tissue swelling (5). Physicians should also evaluate for limb-length discrepancy, which could be the result of a femoral osteoid osteoma (5).
Is osteoid osteomas a benign tumor?
Osteoid osteomas are one of the most common benign bone tumors found. They have a characteristic presentation of nocturnal pain relieved with NSAIDs. Diagnosis can sometimes be difficult due to their location or small size on radiographs. In the future, treatment options will continue to shift towards minimally invasive options, such as arthroscopic excision.
