Abstract
A shoulder prosthesis having a head and an elongate stem portion including a proximal end connected to the head, a distal section for insertion into a medullary canal of a humeral bone and an alignment section disposed between the proximal end and distal section. The alignment section includes a plurality of reference marks positioned to facilitate placement of the prosthesis in the bone at a previously determined position.
Claims16
Apparatus for repairing a fractured humeral bone comprising:
- a shoulder prosthesis having a shaft positionable within the medullary canal of a humeral bone;
- and
- a positioning jig for positioning the shoulder prosthesis at a desired height in the medullary canal, wherein the positioning jig includes
- a first member positionable adjacent the humeral bone,
- a second member coupled to the first member and configured to engage an exposed portion of the humeral bone to support the first member adjacent the humeral bone, and
- a third member coupled to the first member and configured to engage the shoulder prosthesis and hold the shoulder prosthesis at the desired height in relation to the exposed portion of the humeral bone.
3 more elements
Apparatus for repairing a fractured humeral bone comprising:
- a shoulder prosthesis;
- and
- a positioning jig for positioning the shoulder prosthesis at a desired height in the medullary canal of the humeral bone, wherein the positioning jig includes
- a first mechanism configured to engage an upper portion of the humeral bone, and
- a second mechanism coupled to the first mechanism and configured to engage and hold the shoulder prosthesis at the desired height relative to the upper portion of the humeral bone.
2 more elements
Apparatus for repairing a fractured humeral bone comprising:
- a shoulder prosthesis;
- and
- a positioning jig for positioning the shoulder prosthesis with a desired retroversion in the medullary canal of the humeral bone, wherein the positioning jig includes
- a mounting mechanism configured to removably attach to the shoulder prosthesis;
- and
- an alignment rod coupled to extend from the mounting mechanism at a predetermined retroversion angle relative to the shoulder prosthesis such that when the alignment rod is aligned relative to a patient's flexed forearm, the shoulder prosthesis is positioned with the predetermined retroversion in the humeral bone.
