A surgical navigation module comprising: (a) a microcomputer; (b) a tri-axial accelerometer; (c) a tri-axial gyroscope; (d) at least three tri-axial magnetometers; (e) a communication module; (f) an ultrawide band transceiver; and, (g) at least four ultrawide band antennas.

Embodiments provide an adjustable cage template for determining a cage for use in a spinal surgery. The adjustable cage template may include top and bottom cage template, control supports. A configuration of the cage template may be modified and sensors may measure forces applied to the cage template during the modification of the cage template configuration. Modifications to the cage template include rotation of the top cage template relative to the bottom cage template, vertical translation of the top cage template relative to the bottom cage template, or both rotation and vertical translation of the top and bottom cage templates. Information associated with measurements from the sensors may be output to determine whether a current configuration of the cage template is optimal and a final cage template may be selected for the spinal surgery based at least in part on the output information.

In a general aspect, an apparatus can include a plate configured for implantation in a body of a patient. The plate can include a plurality of pores and be configured for placement between a cancellous bone of a spinal vertebra and a corresponding cartilaginous endplate as a replacement for a bony endplate of the spinal vertebra.

A patient-specific porous metal prosthesis and a method for manufacturing the same are provided. The orthopaedic prosthesis may be metallic to provide adequate strength and stability. Also, the orthopaedic prosthesis may be porous to promote bone ingrowth.
