AI Technical Summary

Problems solved by technology

The margin for error in spinal surgery is quite small, particularly because of the sensitivity of the spinal cord and the risk inherent with invasive procedures around the spinal cord.
In particular, the dimensions of vertebral bone available for setting fasteners are fairly limiting.
Any misalignment of the screw within the plate hole risks tissue damage and spinal cord injury.
In addition, improperly seated screws may result in an unstable or insecure connection of the plate to the bony material, thus potentially defeating the usefulness of the plate.

Embodiment Construction

[0051] Referring to FIG. 1, there is shown an exemplary surgical drill-guide assembly 5, which is adapted for use with a cervical spine-locking bone plate having a plurality of fastener holes. While the surgical drill-guide assembly is described in conjunction with a cervical locking plate it will be appreciated that the reference to a cervical locking plate is only exemplary, and that the surgical drill-guide assembly can be used with a variety of bone plates, including a locking and a nonlocking bone-plate as well as for example, bone plates for long bones, maxillofacial applications, etc.

[0052] This embodiment of a drill-guide assembly 5 can be secured or locked into a fastener hole in a bone plate. A related embodiment of a drill-guide assembly 500 that can be secured or locked into a drill recess 354 is shown infra in FIGS. 12A-13B. Locking or securing may facilitate precision in the surgical procedure, for example, drilling or fastening screws or other similar fasteners. More...
