Abstract:
A method is provided for delivering an implant for replacing a portion of an articular surface. The method may include forming a socket in an articulating feature that is capable of moving relative to the articular surface. An implant may be placed in the socket and the articulating feature may be moved relative to the articular surface to generally align the socket with an implant site formed in the articular surface. The implant may be transferred from the socket into the implant site.
Abstract:
A system and method may be used for accessing an articular surface and for preparing an implant site on the articular surface. The method may include locating a portion of the articular. An access passage may be drilled towards the articular surface though bone behind the articular surface. An implant site may be excised in the articular surface relative to an axis defined by the access passage.
Abstract:
A method according to one embodiment may provide access to an articular surface of a bone. The method includes forming a passage through at least a portion of the bone. The passage provides an opening in the articular surface. The method further includes inserting a tether through the passage. The tether inserted through the passage can be coupled to at least one device from an insertion site remote from the articular surface. The tether can be withdrawn through the passage to convey the device to a location proximate the articular surface.
Abstract:
Embodiments of devices, apparatuses, kits, and methods for repairing and/or augmenting the articular surface and/or articular rim of a joint (e.g., repairing the anterior glenoid rim after an anterior shoulder dislocation).
Abstract:
A system, method for replacing at least a portion of first articular surface cooperating with a second articular surface including a prosthetic implant. The method including creating a socket in the first articular surface generally opposite the prosthetic implant. A graft of biological material is installed in the socket, providing a biological replacement of a portion of the first articular surface.
Abstract:
Embodiments of apparatuses and examplary methods for microfracture (e.g. forming a plurality of microfractures in a bone to encourage cartilage regeneration).
Abstract:
Sheaths for implantable fixation devices and methods of using the sheaths are disclosed. Sheaths have a flexible body with a perforated wall, and an interior of the body is sized and shaped to receive the fixation device. Sheaths include a plurality of flexible or inflexible tubes arranged to form a ring, where the central cavity defined by the ring is sized and shaped to receive the fixation device.
Abstract:
A method for excising a portion of an articular surface using a retrograde procedure. An access tunnel is provided extending through a bone and to the articular surface. A central shaft is inserted through the access tunnel to the articular surface and a cutter is coupled to the central shaft. The cutter is coupled to the central shaft to allow the cutter to rotate with the central and to allow the cutter to be tiltable relative to the central shaft. The cutter is rotated and a retrograde force is applied to the cutter to urge the cutter into the articular surface.
Abstract:
A tibial resurfacing system is provided that includes a drill guide, bone chisel and implant. In one aspect, the system includes a drill guide that includes a targeting ring that is shaped to be placed on the superior tibial surface and a bore section that is connected to the ring to create an axis through the tibia to the superior tibial surface in the vicinity of the targeting ring. The drill guide permits a drill pin and/or drill to be advanced through the tibia to the superior tibial surface. In another aspect, a bone chisel is provided that includes an elongated tubular structure having a first end and a bone-cutting end, and the bone-cutting end is terminated in a transverse angle thereby creating an elliptical bone-cutting face. In another aspect, an implant is provided that includes an angled bearing element formed of a cylindrical member having a first end and a second end. The first end is formed at an angle that creates an elliptical face of the first end, and the first end defines a load-bearing surface of an articular surface.
Abstract:
An implant for replacing a portion of an articular surface including a load bearing surface and a bone contacting region. The load bearing surface had a contour defined by a first curve string which is based on a contour of the articular surface being replaced in a first plane. The load bearing surface of the implant is further defined by the contour of the articular surface being replaced in a second plane, in which the first and second planes are mutually intersection planes.
