The asymptomatic and apparently idiopathic ivory vertebra is often a very problematic clinical situation. Previous studies have hypothesized that although several etiologies have been known to be responsible for producing ivory vertebrae, the most likely etiology, particularly for so-called âidiopathicâ ivory vertebrae, is early and asymptomatic Pagetâs disease of bone.
The series that began the franchise, Mighty Morphin Power Rangers (an American adaptation of the 1992 Japanese Super Sentai Series, KyÅryÅ« Sentai Zyuranger), began broadcasting as part of the Fox Kids block of programing that aired on the FOX network. It lasted for three seasons (from 1993 to 1996).
ABC Family, another Disney-owned network, also used to air Power Rangers until it did away with its Jetix timeslot after August 31, 2006. On February 12, 2009, Toon Disney ended in the wake of Disney XD, ending cable airings of Power Rangers in certain areas of the United States.
