ABSTRACT:
In the medical treatment and examination of animate patients, means to flex and secure a spinal column against movement, exclusive of applying pressure to the head and/or neck, comprising coactively adjustable seat and shoulder engaging elements, arranged to flex the spinal column in an optimum posture of flexure, while simultaneously restraining the patient against movement of his spinal column. Coactive plates engaging patient's shoulders and the seat under and around the pelvis are compressed while the patient is strapped therein, whereby the vertebral column is bowed posteriorly, thus widening the inter-vertebral space for introduction of the spinal tap needle therein. The mechanism permits the patient's pelvis to be advanced anteriorly so that it is sustained in the same vertical plane as the shoulders, whereby flexion of the vertebral column is obtained, instead of leaning the patient out of vertical axis, a normal vertical or horizontal axis.
