Abstract: A table is shown suitable for use in supporting, manipulating and positioning human bodies or cadavers during examination, diagnosis and experimentation involving the spine. A pelvic support and a thoracic support are separately slidably mounted on a frame base table. Each support is provided with positioning rods which may be placed in predrilled holes in the pelvic and thoracic regions respectively. The positioning rods are pivoted for rotation so that the cadaver's spine may be controllably and adjustably positioned to simulate forward bending motion of the spine. The thoracic support is pivoted along two axes to provide lateral bending and rotation adjustments. Sensitive plates are positioned below and to the side of the cadaver for sequential radiographic analysis of the spinal region between the positioning rods during various postures controlled by adjustment of the rods and supports. Suitable indexing and locking mechanisms are provided so that a series of sequential positions may be examined.
