Possible joint space narrowing (normal joint space is at least 2 mm at the superior acetabulum) [7] and osteophyte formation 2 Definite osteophyte formation with possible joint space narrowing 3 Multiple osteophytes, definite joint space narrowing, sclerosis and possible bony deformity 4
Osteophytes form because of the increase in a damaged joint's surface area. This is most common from the onset of arthritis. Osteophytes usually limit joint movement and typically cause pain. [6] Osteophytes form naturally on the back of the spine as a person ages and are a clinical sign of degeneration in the spine.
The typical changes seen on X-ray include: joint space narrowing, subchondral sclerosis (increased bone formation around the joint), subchondral cyst formation, and osteophytes. [54] Plain films may not correlate with the findings on physical examination or with the degree of pain. [55]
Intermediate grade 1 shows mild sclerosis of the head and acetabulum, slight joint space narrowing, and marginal osteophyte lipping. Grade 2 presents with small cysts in the femoral head or acetabulum, moderate joint space narrowing, and moderate loss of sphericity of the femoral head.
MRI and X -ray show narrowing of the joint space with secondary degenerative changes in the acetabulum, which is the socket portion of the hip that is a part of the pelvis, such as cysts, osteophytes, and cartilage destruction.
The diagnosis of DDD is not a radiologic diagnosis, since the interpreting radiologist is not aware whether there are symptoms present or not. Typical radiographic findings include disc space narrowing, displacement of vertebral bodies, fusion of adjacent vertebral bodies, and development of bone in adjacent soft tissue (osteophyte formation).
This separation of the cavity space allows for separate movements to occur in each space. The presence of an articular disk also permits a more even distribution of forces between the articulating surfaces of bones, increases the stability of the joint, and aids in directing the flow of synovial fluid to areas of the articular cartilage that ...
They may pass from the main joint cavity into a neighboring synovial cyst. For this reason, a mass may not be appreciated within the actual joint space itself. [citation needed] Additional radiographic findings include joint effusion and degenerative changes such as joint space narrowing, subchondral sclerosis, and osteophyte formation.
