Disc Problems

The shock-absorbing discs that separate the bones in the spine are probably the most common reason for spine surgery. The disc is much like a jelly doughnut, in that there is an outside wall to the disc and a soft center. The “jelly” is the inner spongy portion of the disc, called the nucleus pulposus. Encircling the jelly nucleus are hard bands of fibrous tissue called the annulus fibrosis, or disc wall.

Minimally Invasive Spine Surgery

Spinal deformities become serious when they progress and threaten to cause severe pain and/or permanent disability. In other cases, some people with spinal deformities may not even know they have it. Treatment of these conditions aims at minimizing progression of the disease and preventing further growth.

Spinal Deformities

Skeletal irregularities place strain on the vertebrae and supporting muscles, tendons, ligaments and tissues supported by spinal column. These irregularities include scoliosis, a curving of the spine to the side; kyphosis, in which the normal curve of the upper back is severely rounded; lordosis, an abnormally accentuated arch in the lower back; back extension, a bending backward of the spine; and back flexion, in which the spine bends forward.
