A guide member of the guiding device has a slot for receiving a bone resector and enabling accurate resection of bone around the joint.
Claims21
A method of resecting bone in joint replacement surgery comprising:
- removably securing a bone marker device to a bone by connecting the bone marker device to a hole in the bone, wherein the bone has a first portion that is to be removed and a second portion that is not to be removed, and wherein the hole is formed in the first portion of the bone and the hole does not extend to the second portion of the bone;
- mapping the bone with the bone marker device;
- if required, adjusting the bone marker device;
- cutting the bone in accordance with the mapping;
- and
- removing the first portion of the bone including the entire hole.
A method of resecting bone in joint replacement surgery comprising:
- connecting a bone pin or bone screw to a location of a bone that is to be removed in joint replacement surgery,
- wherein the bone pin or bone screw is adapted so that a bone marker is mounted or mountable to the bone pin or bone screw for use in mapping of the bone,
- wherein the bone has a first portion that is to be removed and a second portion that is not to be removed and the bone pin or bone screw is connected only to the first portion;
- and
- wherein the step of connecting the bone pin or bone screw to the first portion of the bone causes damage to the first portion of the bone but not the second portion of the bone;
- the method further comprising:
- mapping the bone with the bone marker;
- cutting the bone in accordance with the mapping;
- and
- removing the first portion of the bone including all of the damage caused by the step of connecting the bone pin or bone screw.
A method of resecting bone in joint replacement surgery comprising:
- connecting a first guide member to an attachment location of a bone that is to be removed in joint replacement surgery,
- wherein the bone has a first portion that is to be removed and a second portion that is not to be removed, and wherein the attachment location is on the first portion and the first guide member is connected to the first portion at the attachment location by a bone pin or bone screw that extends into the first portion and not the second portion of the bone;
- cutting the bone using, during at least part of the cutting, a bone saw that is guided by the first guide member while the first guide member is connected to the first portion of the bone by the bone pin or bone screw;
- and
- removing the first portion of the bone including the attachment location and damage caused by the step of connecting the first guide member to the attachment location.
