Other symptoms include narrowing of the joint space, synovial membrane thickening, osteophyte
formation and increased density of subchondral bone.
OA is characterized by classical features at histopathological level including cartilage degradation, reduced bone mineral density, osteophyte
formation, synovitis and capsule thickening2.
Another study of the lumbar spine and femoral bone mineral densities in patients found that all patients had lower than normal BMD at the femoral neck but had overestimated lumbar spine BMD likely due to intervertebral disc calcification and osteophyte
Thorax CT angiography revealed a lession protruding into mediastinum which was thought to behyperthrophy of the bone or osteophyte
. It was below the right subclavian artery and was compressing on trachea at the junction of right common carotid artery and right subclavian artery (Figure 2).
TMJ osseous changes were classified to (1) erosion: a decreased density of the cortical and subcortical layers of the condylar bone, (2) flattening: a loss of smooth and divergence from the convex shape of the condyle, (3) osteophyte
: local outgrowth of bone arising from a mineralize joint surface, and (4) sclerosis: an increased density of the cortical bone extending into bone marrow (Figure 1).
These images may demonstrate a spiculated osteophyte
or calcified disc extrusion which are occasionally implicated in CSF leaks, and can be hard to identify once intrathecal contrast has been adminstered.
Sciatica can occur by osteophyte
(bony) growth in the exit area of the lumbosacral plexus.
Beyond simply identifying increasing radiographic severity of the affected knee as having an association with improved patient outcomes, we aimed to determine the association of discrete radiographic variables, such as mechanical alignment, osteophyte
size, location, and subluxation of the patellar or tibia, with positive outcomes following surgery.
There was an osteophyte
in the tibial tuberosity in the lateral left knee X-rays.
Osteoarthritis (OA) is a progressive disease with an incidence increasing steadily with age while structural changes include articular cartilage damage, osteophyte
formation, and subchondral bone changes.
35(43.2%) patients had cervical spine stenosis secondary to osteophyte
and hard disc, 15(18.5%) patients had cervical stenosis with soft discs at multiple levels, 10(12.3%) patients had ossified posterior longitudinal ligaments, 10(12.3%) patients had collapsed vertebra secondary to metastasis, 7(8.6%) patients had collapsed vertebra secondary to plasmacytoma and 4(4.9%) patients had collapsed vertebra secondary to old carries spine.
The region of entrapment was identified with EMG, while ganglion cyst, osteophyte
and lipoma differentiation was achieved with MRI"
