The scapula, more commonly known as the shoulder blade, is a flat bone shaped much like a triangle. This bone attaches the arm bone to the bones of the ribs. Pain in this area of the body is quite common and can have several potential causes, the most common being excessive or strenuous physical activity. Scapula pain can also be caused by sleeping position or degenerative diseases such as arthritis.
Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.ompact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
In a classic case of lumbar spondylosis, the space between discs in the lumber spine becomes narrowed. As a result, the patient develops numbness, tingling, and pain which seem to radiate out from the area. These symptoms are the result of pressure on the nerves as they exit the spinal cord.or mild cases, medications can be used to manage the pain caused by lumbar spondylosis, and physical therapy may be used to increase flexibility and strengthen the spine. Patients are sometimes advised to adopt a diet and exercise regimen which promotes general physical health.
