1. A system for holding and orienting a cadaver specimen, the system comprising:
a platform having a top surface and a bottom surface; and
a first arm assembly having a distal end and a proximal end, wherein the proximal end is rotatably and reversibly attached to the top surface of the platform at a first joint and wherein the distal end comprises a first bone anchor assembly rotatably and reversibly attached thereto,
wherein the first arm assembly comprises a lower arm segment and an upper arm segment and wherein the lower arm segment and the upper arm segment are reversibly attached at a second joint configured to allow the lower arm segment and the upper arm segment to pivot relative to each other at different angles;
wherein the lower arm segment comprises a proximal end rotatably and reversibly attached to the top surface of the platform at the first joint;
wherein the upper arm segment comprises a distal end comprising a rotation assembly rotatably and reversibly attached to the first bone anchor assembly;
wherein the upper arm segment and the rotation assembly are configured to pivot relative to each other at different angles; and
wherein the rotation assembly is configured to allow the attached first bone anchor assembly to rotate relative to the distal end of the upper arm segment;
wherein the first bone anchor assembly comprises a handle comprising an elongated cylindrical structure having a proximal end and a distal end and a cortical rod comprising an elongated blade structure having a proximal end and a distal end and at least one through-hole therebetween, wherein the proximal end of the cortical rod is connected to the distal end of the handle; and
wherein the first bone anchor assembly further comprises a clamp attached to the proximal end of the cortical rod and adjacent the distal end of the handle wherein the clamp is connected to the cortical rod by insertion of a pin, bolt or screw through a through-hole of the cortical rod and through a through-hole of the clamp.
