<p>A spinal compression device includes a shoulder harness, a footplate assembly connected to the shoulder harness by at least one connecting member, At least one hydraulic actuator is mechanically coupled to the footplate assembly. The hydraulic actuator has proximal and distal ends and a piston mechanically coupled to the connecting member. A hydraulic energy source is in fluid communication with the hydraulic actuator through hydraulic lines. The footplate assembly is only connected to the hydraulic source by the hydraulic lines.</p> |
