X-ray showing osteophytes of spondylosis of the lumbar spine. A range of bone-formation processes are associated with aging, degeneration, mechanical instability, and disease (such as diffuse idiopathic skeletal hyperostosis). Osteophyte formation has classically been related to sequential and consequential changes in such processes.
A compression fracture is a collapse of a vertebra. It may be due to trauma or due to a weakening of the vertebra (compare with burst fracture ). This weakening is seen in patients with osteoporosis or osteogenesis imperfecta , lytic lesions from metastatic or primary tumors , [ 1 ] or infection. [ 2 ]
In some, the x-ray findings may correspond to symptoms of back stiffness with flexion/extension or with mild back pain. [2] Back pain or stiffness may be worse in the morning. [4] Rarely, large anterior cervical spine osteophytes may affect the esophagus or the larynx and cause pain, difficulty swallowing [5] [6] or even dyspnea. [7]
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 Large osteophytes, marked joint space narrowing, severe ...
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).
Schmorl's nodes are fairly common, especially with minor degeneration of the aging spine, but they are also seen in younger spines. Schmorl's nodes often cause no symptoms, but may simply reflect that "wear and tear" of the spine has occurred over time; they may also reflect that bone strength was at one time somewhat compromised, perhaps due to a vitamin D deficiency although this has yet to ...

The approach varies depending on the site and cause of root compression. Commonly, osteophytes and portions of intervertebral disc are removed. [14] Fusion surgery: Performed when there is evidence of spinal instability or mal-alignment. Use of instrumentation (such as pedicle screws) in fusion surgeries varies across studies. [13]
