Transosseous core approach and instrumentation for joint replacement and repair

a transosseous core and joint technology, applied in the field of transosseous core approach for joint replacement and/or treatment, can solve the problems of affecting the healing effect of the joint, so as to facilitate the treatment of the articular surface and/or other structures in the joint, and without substantially compromising the physical integrity and physiological viability of the join

Benefits of technology

[0006] In the present invention, a joint is entered via a route passing through a pathway provided in a portion of a joint bone. Such pathway is made by taking out a bone core from the bone in or adjacent to the joint without substantially compromising physical integrity and physiological viability of the joint. Typically the main route for the present invention traverses through a more-accessible bone of the joint which can be aligned with a less-accessible bone of the joint to facilitate treatment of the articular surfaces and / or other structures in the joint.
[0007] The present invention thus provides a new method and instrumentation for gaining access to areas in and around the joint surfaces to treat problems of the joint as well as to provide new implants and instrumentation adapted for the new method. The transosseous core approach of the present invention has at least two main advantages over conventional surgical exposures. A first is that the present invention requires substantially smaller incisions than standard exposures. A second is that the present invention does not substantially interfere with normal anatomical structures surrounding the joint such as vascular, nervous, muscular, ligamentous, and other soft tissues of the joint and, therefore, is less invasive. Additionally, in many cases the exposure obtained by the transosseous core approach provides better and more direct access to areas of the joint not found in current exposures.

Problems solved by technology

Conventional methods for gaining access into the joints typically require wide exposures and joint dislocation.
See for example U.S. Pat. No. 4,550,450, entitled “Total Shoulder Prosthesis System,” and U.S. Pat. No. 5,507,833, entitled “Hip Replacement and Method for Implanting The Same.” These classical wide exposures damage large area of tissue, create large scars, jeopardize neurovascular structures, produce considerable blood loss, increase the potential for other significant complications, and increase the risk of infection.
The amount of tissue disrupted increases the healing time and the physiological strain on the patient because the amount and severity of postoperative pain correlate directly to the size of the incision and extent of surgery.
Traditional wide exposures can also create limits on the functional results of surgery to treat joint problems by the sequlae introduced by the exposure itself.
More recent developments in arthroscopic techniques may reduce the amount of trauma to which a patient may be subjected, but many procedures are not amenable to arthroscopic techniques and frequently such procedures still entail damage to soft tissue structures surrounding the joint such as the articular capsule.
The inability to reach desired rehabilitation goals often results in an overall inferior and / or an unsatisfactory result.
These additional drawbacks of conventional joint surgical exposures and treatments contribute to reduce the ultimate outcome of the surgical intervention, often introducing unwanted and unnecessary sequlae.

Embodiment Construction

[0049] The present invention can be used to treat problems that occur in almost any joint, in particular diarthroidal joints. A common element or feature of the present invention, regardless of which joint is treated, is that the joint surface(s) to be treated are approached through a first bone, i.e., the transversed bone. This is accomplished by creating an exposure through a channel or hole that is made in the transversed bone overlying the joint surface to be addressed. Preferably, the channel is made by a transosseous core, which core can be replaced after treatment or placement of an implant to reconstitute the integrity of the bone substance or surface. In this manner, the joint surface to be treated is approached from the “back side” such that highly invasive dislocation of the joint and wide exposure incisions are not required to create the necessary access. Depending upon the degree of treatment necessary, the present invention also avoids or minimizes in appropriate cases...

Abstract

A method and instrumentation is disclosed for gaining access to areas in and around joints for treatment and to provide new implants and instrumentation adapted for the new method. In a transosseous core approach, the joint is entered through a pathway provided in a portion of a joint bone. Such pathway is preferably made by removing a bone core from the bone in or adjacent to the joint, wherever possible without substantially compromising physical integrity and physiological viability of the joint. A route for the transosseous core approach traverses through a more-accessible bone of the joint which can be aligned with a less-accessible bone in order to facilitate treatment of articular surfaces and / or other structures in the joint. Implant modules are provided which can be inserted into the joint through the transosseous pathway and assembled in situ inside the joint to form an implant assembly.
