Situated beneath an articulation or joint
The subarticular recesses are located in the lumbar spinal canal. A narrowing of the subarticular recesses is referred to as lateral recess stenosis for which surgery may be required.
Subarticular sclerosis is the hardening or thickening of the bone beneath the joint or articulation. It is diagnosed through an X-ray.
A subchondral cyst is a fluid-filled sac under the cartilage.
what is narrowing of the right subarticular zone of the spinal canal
A cyst is an unusual or abnormal structure consisting of an endothelial lining around a collection of harmless fluid. Subarticular means it is below the surface of the joint, in the bone rather than actually in the joint space. The medial femoral condyle is the projection of the end of the femur bone on the inside of the leg in the knee joint.
Intra-articular pathology would be disease of the articular cartilage and would encompass arthritis, cartilage erosion, neoplasia and developmental disorders of cartilage and subarticular bone.
This MRI finding indicates enlargement of the endplates in the t11-t12 and t12-L1 spinal segments, as well as hypertrophy in the right lateral recess and subarticular zone at the L1-L2 level. This can lead to narrowing of the spinal canal and potential compression of nearby nerves, potentially causing symptoms like pain, numbness, or weakness in the lower back and legs. Further evaluation and treatment may be needed depending on the severity of symptoms.
