METHOD AND APPARATUS FOR PERFORMING AN OPEN WEDGE, HIGH TIBIAL OSTEOTOMY

摘要

A keyhole drill guide stabilizer for stabilizing a drill guide when forming a second keyhole after the formation of a first keyhole, wherein the drill guide comprises a first drill bore and a second drill bore, the keyhole drill guide stabilizer comprising a body sized and shaped so as to make a close sliding fit with (i) the first bore of the drill guide, and (ii) the first keyhole, whereby to reduce the possibility of any positional variation between the first and second drilled keyholes. A keyhole drilling system for forming first and second keyholes in bone, the system comprising: a drill guide comprising a first drill bore for drilling a first keyhole and a second drill bore for drilling a second keyhole; and a keyhole drill guide stabilizer for stabilizing the drill guide when forming the second keyhole after the formation of the first keyhole, the keyhole drill guide stabilizer comprising a body sized and shaped so as to make a close sliding fit with (i) the first bore of the drill guide, and (ii) the first keyhole, whereby to reduce the possibility of any positional variation between the first and second drilled keyholes. A method for stabilizing a drill guide when forming a second keyhole after the formation of a first keyhole, the method comprising: providing a drill guide comprising a first drill bore for drilling a first keyhole and a second drill bore for drilling a second keyhole; drilling the first keyhole; providing a keyhole drill guide stabilizer comprising a body sized and shaped so as to make a close sliding fit with (i) the first bore of the drill guide, and (ii) the first keyhole; advancing a keyhole drill guide stabilizer through the drill guide and into the first keyhole; and drilling the second keyhole while the keyhole drill guide stabilizer is maintained in the first keyhole, whereby to reduce the possibility of any positional variation between the first and second drilled keyholes. Apparatus for protecting the neurological and vascular structures located at the back of the knee, the apparatus comprising: a base portion; a curved portion connected to the base portion; and a distal tip portion connected to the curved portion. Apparatus for use in performing an open wedge, high tibial osteotomy, the apparatus comprising: an apex pin; a positioning guide for attachment to the tibia, the positioning guide comprising an opening for slidably receiving the apex pin therein so as to direct the apex pin into the tibia; and a collet nut mounted to the positioning guide for securing the apex pin within the opening of the positioning guide. Apparatus for use in forming a wedge-like opening in a bone, the apparatus comprising: an opening jack comprising first and second arras pivotally connected to one another intermediate their lengths; and a dogbone spacer for extending between the first and second arms of the opening jack so as to confirm the appropriate disposition of the first and second arms of the opening jack, whereby to confirm the creation of an appropriately-sized wedge-like opening in the bone. Apparatus for use in confirming the creation of an appropriately-sized wedge-like opening in a bone, wherein two keyholes communicate with the wedge-like opening in the bone,
