An intramedullary cavity assembly includes a guide wire, a cannula having a trocar tip, emitters, sensors, exuding ports, and withdrawing ports. The emitter sends radiation into intramedullary tissue. The sensors, which detect effects thereof, include cameras or other radiation detectors. The assembly directs movement of the guide wire, and can exude/withdraw bodily fluids. Robotic control inputs/outputs, including a visualization element, operate the assembly. The guide wire is steerable from outside the body, and is capped with a trocar cannula, having surfaces transparent to energies used for visualization and operation. The visualization element includes computing devices, which receive sensor information, process it, and present it, so medical personnel can readily understand a 3D assessment of the assembly and intramedullary cavity. Medical personnel operate the assembly to emit energy or substances into tissues nearby, thus readily moving the assembly within the body and delivering treatment inside the body.

Intraosseous and intramedullary visualization

A spinal implant for implantation in an intervertebral space is provided, such that the implant may provide a back-out prevention feature and may also provide a visual indication of whether the back-out prevention feature is engaged. The visual indication may be a contrast between a circular visible shape of the screw head and a non-circular visible shape of the screw head. The back-out prevention feature may provide engagement of a tapered thread in the screw head with an internal thread of the implant. A hard stop may also be provided. Such back-out prevention feature may also provide a torque-based indication of engagement or non-engagement of the back-out prevention feature. The implant may possess a polymeric posterior body joined to a metallic anterior body.
