Abstract
A targeting apparatus for use in resectioning a femur when performing transfemoral osteotomy surgery has a drill guide element which includes a line of drill openings each of which is adapted to guide a drill for drilling holes in the femur. A connector is provided for securing the drill guide element to a femur to be resectioned with the line of openings extending in a proximal/distal direction along the femur.
Claims42
A targeting apparatus for use in resectioning a femur when performing transfemoral osteotomy surgery comprising a drill guide element which includes a line of drill openings each of which is adapted to guide a drill and means for engaging an outer surface of an exposed femur for rigidly securing said drill guide element to the femur to be resectioned with the line of openings extending in a proximal/distal direction wherein the drill guide element also includes a longitudinally extending cutting guide offset from said line of openings, the guide for guiding a means for exposing the femur along a proximal/distal line.
A targeting apparatus for use in resectioning a femur when performing transfemoral osteotomy surgery comprising a drill guide element which includes a line of drill openings each of which is adapted to guide a drill and means for rigidly securing said drill guide element to a femur to be resectioned with the line of openings extending in a proximal/distal direction wherein the drill openings are angled in relation to each other so that the openings are more closely spaced apart on the outer side of the element than on the inner side adjacent the femur.
A targeting apparatus for use in resectioning a femur when performing transfemoral osteotomy surgery comprising a drill guide element which includes a line of drill openings each of which is adapted to guide a drill and means for rigidly securing said drill guide element to a femur to be resectioned with the line of openings extending in a proximal/distal direction and further comprising means for locating the securing means on a partially resectioned transverse end of the femur after a first transverse cut has been made.
The targeting apparatus for use in performing transfemoral osteotomy surgery comprising a drill guide element which includes a line of drill openings each of which is adapted to guide a drill and means for rigidly securing said drill guide element to a femur to be resectioned with the line of openings extending in a proximal/distal direction and further comprising a support element provided with a drill guide, means for securing the support element to a resectioned femur, means for connecting the securing means for the drill guide element to the support element, and means for adjusting the angular position of the drill guide in relation to the resectioned femur about a proximal-distal axis.
A targeting apparatus for use in resectioning a femur when performing transfemoral osteotomy surgery comprising a drill guide element which includes a line of drill openings each of which is adapted to guide a drill and means for rigidly securing said drill guide element to a femur to be resectioned with the line of openings extending in a proximal/distal direction and further comprising a support element is in the form of an L-shaped frame, one arm of which carries the drill guide and the securing means and the other arm carrying the means for connection to a femoral prosthesis which is to be implanted.
The targeting apparatus as claimed in claimed 21 in which the securing means are connected to the L-shaped frame by an adjustable bracket which can be adjusted in proximal-distal directions on the frame and in relation to which the femur securing means can be angularly adjusted about a proximal-distal axis.
A targeting apparatus for use in resectioning a femur when performing transfemoral osteotomy surgery comprising a drill guide element which includes a line of drill openings each of which is adapted to guide a drill and means for rigidly securing said drill guide element to a femur to be resectioned with the line of openings extending in a proximal/distal direction and further comprising a guide for locating the resectioned proximal end of the femur.
A method for resecting a long bone comprising:
- attaching a drill guide onto the long bone, the drill guide having a plurality of guide holes extending parallel to a longitudinal axis of the bone;
- resecting the long bone in a direction generally transverse to said longitudinal axis;
- drilling a series of holes into the bone using said plurality of guide holes to form a row of perforations in the bone;
- and
- breaking the bone along said row of perforations.
A drill guide for use in resecting a long bone along a longitudinal extent of the bone comprising:
- a connector for coupling the drill guide to a long bone;
- a drill guide element supported by the connector, said drill guide element including a body having a plurality of drill guide openings, said openings aligned in a pair of parallel circumferentially offset rows, which rows are alignable with the longitudinal extent of the long bone to be resected.
A drill guide for use in resecting a long bone along a longitudinal extent of the bone comprising:
- a connector for coupling the drill guide to a long bone;
- a drill guide element supported by the connector, said drill guide element including a body having a plurality of drill guide openings, said openings aligned in a row, which row is alignable with the longitudinal extent of the long bone to be resected wherein the drill guide openings are angled in relation to each other so that the openings are more closely spaced apart on the outer side of the element than on the inner side adjacent the long bone.
A drill guide for use in resecting a long bone along a longitudinal extent of the bone comprising:
- a connector for coupling the drill guide to a long bone;
- a drill guide element supported by the connector, said drill guide element including a body having a plurality of drill guide openings, said openings aligned in a row, which row is alignable with the longitudinal extent of the long bone to be resected and further comprising a guide for locating the resectioned proximal end of the long bone.
A drill guide for use in resecting a long bone along a longitudinal extent of the bone comprising:
- a connector for coupling the drill guide to a long bone;
- a drill guide element supported by the connector, said drill guide element including a body having a plurality of drill guide openings, said openings aligned in a row, which row is alignable with the longitudinal extent of the long bone to be resected and further comprising a support element in the form of an L-shaped frame, a first arm of which carries the drill guide element and the connector for coupling to the long bone and a second arm which carries a connector for connection to a prosthesis which is to be implanted.
