Structural lateral curvature of an unknown cause.
Large muscles starting at L-1 and becoming wider as it picks up segments from the lower lumbar spine; combines with the iliacus muscle before attatching to the lesser trochanter of the hip.
Lateral curvature of the spine that begins before age 3.
A stalk extending from the base of the brain to the pituitary gland.
The muscles between the ribs.
The immobilization of bone fragments or joints with implants in order to promote healing or fusion.
Formation of a false joint between two spinous processes.
Narrowing of the space between any two vertebral bodies.
A pump which is inserted into the main vessel of the body, the aorta, to help the heart deliver blood to critical organs such as the brain or kidneys.
An invasive study in which a catheter (a small tube) is placed in the artery and contrast material is injected to which makes the blood vessels visible on an x-ray image. The catheter is inserted in the groin into the femoral artery (the artery to he leg) through a needle, and is guided into the arteries in the neck and head. This study is associated with a very small (less than 0.05 % chance of serious complications) and requires the patient to lie in bed for approximately six hours to allow the leg vessel to heal.
A blood clot within the brain.
Within the cranium of the skull.
The overall pressure inside the skull.
Administration of a contrast dye into the ventricles which are chambers in the brain that contain brain fluid.
Refers to medullaris, marrow; (1) withing the medulla oblongata of the brain, (2) within the spinal cord, and (3) within the marrow cavity of bone.

Describing biological phenomena that are made to occur outside the living body traditionally in a test tube. In vitro is Latin for in glass.

Inadequate circulation of blood generally due to a blockage of an artery.
Of equal dimensions. In physiology, denoting the condition when the ends of a contracting muscle are held fixed so that contraction produces increased tension at a constant overall length.
Relating to isotonicity or isotonia. Having equal tension; denoting solutions possesing the same osmotic pressure; more specifically, limited to situations in which cells can neither swell nor shrink.
The lesion is in the pars interarticularis. Three types occur: lytic, fatigue fracture of the pars interarticularis; elongated but intact pars interarticularis; and acute fracture of the pars interarticularis.
