Tips for packing your crib. 1  If you have a portable crib, this will of course be much easier to transport than a stationary one, as most models are collapsible and can be folded up and stowed easily in a personal vehicle or moving truck.
Figure 3. Spondylolisthesis is the forward slippage of a vertebra out of its normal position caused by spondylolysis. The facet joint is no longer able to hold the vertebra in place against the ever-present downward force of body weight. Slippage is measured on a scale from grade 1 slippage (25%) to grade 4 (100%).
Slipped disc: Rupturing of the tissue that separates the vertebral bones of the spinal column. The center of the disc, which is called the nucleus, is soft, springy and receives the shock of standing, walking, running, etc. The outer ring of the disc, which is called the annulus (Latin for ring), provides structure and strength to the disc. The annulus consists of a complex series of interwoven layers of fibrous tissue that hold the nucleus in place. A slipped disc is also known as a herniated disc.
