Abstract
Bone and joint surface reconstruction methods are disclosed for the therapeutic amelioration of joint defects caused by various conditions, injuries, and diseases to help eliminate or reduce pain and return the joint to its proper bio-mechanical function without the need to replace fully or partially the anatomical joint. The joint may specifically include mammalian joints such as the humeroradial joint or other joint of the elbow, wrist, or hand, for example. The methods disclosed herein leverage the significant role the subchondral bone plays in the health status of the afflicted joint.
Claims20
A surgical assembly configured for use in a surgery to be performed relative to a humeroradial or other joint of the elbow, wrist, or hand for intervening in subchondral bone therein to ameliorate one or more defects, the surgical assembly comprising:
- a driver instrument;
- and
- a hybrid subchondral implant-biologic member construct configured to be installed relative to the humeroradial or other joint of the elbow, wrist, or hand and comprising:
- a biologic member having a slit formed therethrough, wherein the slit is arranged so that the driver is extending through the slit, wherein the biologic member is tailored to provide therapeutic effect in the humeroradial or other joint of the elbow, wrist, or hand;
- and
- a subchondral implant engaged with the driver, wherein the subchondral implant is sized and shaped to be received into the subchondral bone of the humeroradial or other joint of the elbow, wrist, or hand, wherein the biologic member is secured to the subchondral implant so that the hybrid subchondral implant-biologic member construct is formed on the driver to facilitate installation into the humeroradial or other joint of the elbow, wrist, or hand by operation of the driver.
A method of intervening in subchondral bone to ameliorate one or more defects while preserving a humeroradial or other joint of the elbow, wrist, or hand using a hybrid subchondral implant-biologic member construct, the method comprising:
- a) surgically opening access to a humeroradial or other joint of the elbow, wrist, or hand joint of the patient;
- b) preparing a site of subchondral bone at the humeroradial or other joint of the elbow, wrist, or hand by removing a circular portion of the subchondral bone while preserving a central post of the subchondral bone in a substantially undisturbed native state;
- c) preparing a hybrid subchondral implant-biologic member construct by:
- 1) forming a slit through a biologic member;
- 2) positioning a driver instrument through the slit;
- 3) engaging the driver instrument with a subchondral implant;
- and
- 4) securing the biologic member to the subchondral implant so that the hybrid subchondral implant-biologic member construct is formed;
- and
- d) installing the hybrid subchondral implant-biologic member construct over a top of the central post in the humeroradial or other joint of the elbow, wrist, or hand.
A method of intervening in subchondral bone to fuse a humeroradial or other joint of the elbow, wrist, or hand using a subchondral implant, the method comprising:
- a) surgically opening access to a humeroradial or other joint of the elbow, wrist, or hand joint of the patient;
- b) preparing a site of subchondral bone at the humeroradial or other joint of the elbow, wrist, or hand by removing damaged tissue in and/or between the subchondral bone of multiple bones along the joint so as to form a bore between the multiple bones along the joint;
- c) preparing a subchondral implant;
- and
- d) installing the subchondral implant construct in the bore so that the subchondral implant is engaging the subchondral bone of the multiple bones along the humeroradial or other joint of the elbow, wrist, or hand, wherein the subchondral implant engaging the subchondral bone of the multiple bones resists relative motion therebetween and thus facilitates fusion of the joint.
