What does Modic 1 mean?
Modic type I endplate change is the most controversial and important of the three types described (see Modic endplate change). It is seen on MRI of the spine and represents the presence of low T1 and high T2 signal within the bone marrow of a vertebral body adjacent to a disk. Type 1 change can enhance and be painful.
What are Modic changes in spine?
Modic changes (MC) are bone marrow lesions seen within a vertebral body on magnetic resonance imaging (MRI), suggestive of being associated with low back pain (LBP). Their presence in clients receiving physiotherapy for low back pain may be of significance when discussing prognosis and benefits of exercise therapy.
What does Modic endplate changes mean?
Modic changes are a term which is used to describe the changes of the vertebral endplate which are related to spinal degeneration. They are most common in the lumbar spine, and whilst they can occur at any level, they are most commonly observed at L4/5 and L5/S1.
What causes Modic endplate changes?
Modic changes in the bones of the spine or the end-plates occur in response to degenerative changes in the discs, pathology, or infections. Type I Modic changes are linked to longstanding degenerative changes.
How are Modic changes diagnosed?
Diagnosing modic changes Modic changes are characterized on MRI (magnetic resonance imaging). In Modic type 2 there are changes in bone marrow, with fatty replacement of formerly red, cellular marrow normally seen there.
Are Modic changes painful?
1. Signal changes in the vertebral body marrow adjacent to the end plates also known as Modic changes (MC) are strongly associated with LBP. 2. MC type 1 are probably more painful than type 2.
What does Modic type 2 mean?
In Modic type 2 there are changes in bone marrow, with fatty replacement of formerly red, cellular marrow normally seen there. With Modic type 2 changes the marrow is substituted by visceral fat, the same kind of fat we have on our hips and bellies.
What is Type 1 and Type 2 Modic changes?
Modic type 1 change represents bone marrow oedema and inflammation; Modic type 2 change represents marrow ischemia and the conversion of normal red haemopoietic bone marrow into yellow fatty marrow [1]; and Modic type 3 change is rare and represents of subchondral bone sclerosis [2].
What are the types of Modic changes?
There are usually three types of Modic changes namely Type I, Type II, and Type III. In type I Modic changes, there is a rapid, unstable and destructive form of spinal degeneration more often than not caused by bacterial infections. Modic changes are one of the leading causes of low back pain after spinal stenosis or disc herniation.
What does Modic type 1 lumbar spine mean?
Modic type 1 lesions in the lumbar spine are strongly associated with low back pain [3–7] and instability [3, 8]. With the passage of time, a large proportion of Modic type 1 change converts to type 2 [1, 4, 7, 9].
What is a Modic change in a disc?
Modic Changes are also associated with inadequate healing and recurrent disc herniation. There are usually three types of Modic changes namely Type I, Type II, and Type III.
What is Modic type 1 osteoporotic changes?
Modic type I (phase one of Modic changes), swelling, and inflammatory changes in spinal bone and endplate are common findings. A neglected Modic type I can progress to type II, where fatty changes occur in the red bone marrow.
