Abstract
A guidance system comprises a first guide configured to be detachably mounted to a first portion of a bone. The first guide has a first axis for alignment with a longitudinal axis of the first portion of the bone. A second guide is mountable on the first guide. The second guide is slidably translatable in a transverse direction relative to the first axis. A third guide is mountable on the second guide. The third guide is selectively positionable along a curved path extending at least part way around the longitudinal axis.
Claims18
A method for using a guidance system, comprising:
- fixing a first guide to a bone;
- cutting the bone to provide a first bone portion and a second bone portion, the first bone portion having a first longitudinal axis, wherein a first axis of the first guide is aligned with the first longitudinal axis;
- mounting a second guide to the first guide, wherein the second guide is slidably translatable at a selected position relative to the first guide along a transverse direction normal to the first longitudinal axis;
- mounting a third guide to the second guide such that the third guide is translatable along a curved path extending at least part way around the first longitudinal axis;
- and
- moving the third guide around the first longitudinal axis to rotate the second portion of the bone to a target angle relative to the first portion of the bone.
A guidance system, comprising:
- a first guide configured to be detachably mounted to a first portion of a bone, the first guide having a first axis for alignment with a longitudinal axis of the first portion of the bone and a first planar surface arranged in perpendicular relation to the first axis;
- a second guide mountable on the first guide, the second guide movable in a transverse direction relative to the first axis and having a second planar surface arranged to slide transversely relative to the first planar surface;
- and
- a third guide mountable on the second guide with the third guide being selectively translatable along a path around the longitudinal axis.
