Surgical Tensor Where Each Distraction Mechanism Is Supported And Aligned By At Least Two Guide Shafts

A surgical apparatus configured to support at least one bone cut for installing a prosthetic component comprising:

• a cage system comprising:
• a cap,
• an anterior medial guide shaft;
• a posterior medial guide shaft;
• an anterior lateral guide shaft;
• a posterior lateral guide shaft;
• and
• a base wherein the anterior medial guide shaft, the posterior medial guide shaft, the anterior lateral guide shaft, and the posterior lateral guide shaft couple between the cap and the base;
• a support holder having a first opening, a second opening, and a threaded opening wherein the anterior medial guide shaft couples through the first opening of the support holder and wherein the anterior lateral guide shaft couples through the second opening of the support holder;
• a first support structure coupled to the support holder;
• and
• a first threaded shaft configured to raise or lower the support holder wherein the first threaded shaft couples through an opening in the base, and wherein the first threaded shaft engages with the threaded opening of the support holder and is configured to move the support holder and thereby the first support structure a predetermined distance to distract the musculoskeletal system when rotated.
