Another common type of kiddie ride is the miniature carousel type. These rides are usually in the form of a small-sized carousel and newer models have the coin-box on the main pillar whereas older units have the coin box on a pole sticking out of the side of the ride.
Degenerative disc disease (ddd) and arthritis are very similar, and often are considered the same. Arthritis, however, is a broader term that can include arthritis to any joint in the body and can include different causes, such as autoimmune, infectious, overuse, traumatic, aging, etc. Ddd is specific to the spine and refers to arthritis that is usually age or overuse related.
Degenerative disc disease. Degenerative disc disease (DDD) describes the natural breakdown of an intervertebral disc of the spine. Despite its name, DDD is not considered a disease, nor is it progressively degenerative. On the contrary, disc degeneration is often the effect of natural daily stresses and minor injuries that cause spinal discs to gradually lose water as the anulus fibrosus, or the rigid outer shell of a disc, weakens.
