Hemispheric spondylosclerosis has on frequent occasion been confused with more life threatening diseases such as metastatic carcinoma, lymphoma and, less threatening but clinically significant, osteoid osteoma. Hemispheric spondylosclerosis presents radiographically as an increase in the vertebral density resembling a dome or helmet as the vertebral body above or below the intervertebral disc space. The convex area of increased density is located usually in the anterior or middle third of the vertebral body. The convex shape of the sclerosis is always preserved.
In 50 percent of the cases, the L4 vertebral segment is affected. Most of the time a periosteal reaction or a circumscribed ossification of the anterior longitudinal ligament develops where the sclerotic region meets the anterior margin of the vertebral body.
Another common finding associated with this entity is that a small erosion can form at the base of the spherical sclerosis. This is apparently due to the extrusion of disc material into the brittle and sclerosed vertebrae. Eight percent of patients with hemispheric spondylosclerosis develop osteophytes on the anterior aspects of the vertebral body. Most cases demonstrate a decrease in height of the adjacent disc space. I has also been reported that nearly 30 percent of patients with hemispheric spondylosclerosis present with a spondyloretrolisthesis.
It is generally accepted that hemispherical spondylosclerosis is due to degenerative disc disease and the subsequent subdiscal sclerosis of the cancellous bone. It constitutes an adaptive thickening of the cancellous trabeculae which develops as the result of the decreased elasticity of the degenerative disc.
Distribution of features of hemispheric spondylosclerosis of the spine:
Typical hemispheric or helmet shape of hemispheric spondylosclerosis with its center in the anterior portions of the vertebra or, less frequently, expanding into the posterior third of the vertebral body -- 100 percent.
Decrease in disc height --87 percent.
At least one very small erosion in the base of the sclerosis -- 85 percent.
Vertebral osteophyte(s) -- 81 percent
Smooth or denticulate periosteal reaction at the anterior contour of the vertebra or ossification of the anterior longitudinal ligament along the sclerosis -- 79 percent.
Caudally directed new bone formation at the anterior base of the sclerosis -- 74 percent.
Multiform spondylosclerosis of the subjacent vertebra -- 64 percent. (Hence in 36 percent of the observations this infradiscal spondylosclerosis was absent.)
Erosion(s) in the region of the intradiscal end-plate -- 36 percent.
Some doctors thrive in a personality-based clinic and have a loyal following no matter what services or equipment they offer, but for most chiropractic offices who are trying to grow and expand, new equipment purchases help us stay relevant and continue to service our client base in the best, most up-to-date manner possible. So, regarding equipment purchasing: should you lease, get a bank loan, or pay cash?
Some pundits say that the upcoming presidential and congressional races, and many local races, might be the most consequential in our country’s history. We do not have the choice of sitting on the sidelines and hoping our patients will carry our water. Unlike other medical professions such as physical therapists, podiatrists, nurses, etc., the health care class (AMA) will not protect us. We must be in the game.
The most common condition affecting the shoulder is rotator-cuff disease. From acute tears to chronic tendinopathy, it’s common and needs a thorough workup. In fact, even asymptomatic shoulders can have full-thickness rotator-cuff rears in up to 40% of instances. Let’s look at additional conditions that can present to the office with weakness, loss of motion and pain in the shoulder beyond rotator-cuff tears.
