CONTOURED CALCANEAL PLATE AND A PERCUTANEOUS DRILL GUIDE FOR USE THEREWITH

摘要

This invention provides a calcaneal plate implanted using a sinus tarsi approach and comprises an anterior section having two locking screw holes, an s-shaped posterior facet section having a four locking holes and which rounds toward the bone at both the inferior and superior edges and is reinforced at the superior edge, and a blade shaped posterior portion having three linearly aligned locking holes and terminating in a tapered portion. There is also, a drill guide assembly having a drill guide column inserted through a hole in a targeting guide and locking to one of the locking holes in the plate, and cannulated drill guide sleeves that lock into holes in the targeting guide in a spaced relation whereby when the targeting guide is locked into the plate, the targeting guide can be used as a handle and wherein locking screws can be implanted percutaneously.

主权项

1. A method of performing a calcaneal surgery on a calcaneus comprising the steps of
forming a sinus tarsi incision on the lateral side of an ankle; selecting a calcaneal plate having an anterior section having a locking screw hole and a posterior section having a screw hole, locking a drill guide column in the locking screw hole of the anterior section; locking a further drill guide which is cannulated to the targeting guide and implanting a screw through that drill guide to fix the calcaneal plate relative to the calcaneus; locking a targeting guide having a through hole about the drill guide column in a spaced relation; and using the targeting guide as a handle to insert the posterior section of the calcaneal plate through the sinus tarsi incision.
