Fully articulated Real Human Medical Spine which shows Sacralization of the fifth lumbar vertebra. This is a congenital anomaly, in which the transverse process of the last lumbar vertebra (L5) fuses to the sacrum on one side or both. These anomalies occur in about 3.5 percent of people. This old rare example stands 68cms tall with the base measuring 15cms diameter. A superb example for study or display.
