An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a guide configured to be coupled generally perpendicular to the first bone proximate to the defect. The guide includes a body portion defining a plurality of excision passageways. The excision passageways each define a generally cylindrical core pathway configured to extend generally perpendicular to the first bone which partially overlaps with an adjacent generally cylindrical core pathway. A projection associated with each of the plurality of the generally cylindrical core pathways defines a truncated cylindrical excision site extending through a portion of the articular surface. Each truncated cylindrical excision site partially overlaps with at least one adjacent truncated cylindrical excision site.

A glenoidal implant for a shoulder prosthesis includes an articular body having two opposite faces which are an articulation face suitable for cooperating with an articulation head of a humeral implant, and an anchoring face from which at least one anchoring stud protrudes for an anchoring in the glenoid cavity including a main anchoring stud at least partially covered with a porous or rough surface coating promoting an osseointegration. The main anchoring stud is provided internally with a central hole extending along a central axis of symmetry of the main anchoring stud and provided to allow guiding a trephine.

Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of the SI-joint and/or lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, SI-joint fusion or fixation; lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.

Powered drivers operable to insert an intraosseous device into a bone and associated bone marrow are disclosed. Some of the present powered drivers may include a housing having a distal end and a proximal end; a motor disposed in the housing; a driveshaft at the distal end of the housing; and a gearbox coupled to the motor and to the driveshaft. Activation of the motor causes rotation of the driveshaft. The housing may include a power source configured to power the motor. The driveshaft may be slidably disposed in the housing and configured such that, upon application of a threshold force on the driveshaft in the direction of the proximal end of the housing, the driveshaft will slide toward the proximal end of the housing to cause an electrical circuit between the motor and the power source to close.

A device for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions using intra articular localization has a guide, a locating arm, a set of attachment assemblies and a tubular sleeve. The device comprises a device body and an attachment assembly mounted on the device body. The attachment assembly includes a main body and at least one closure body. The main body has an elongated recess therein. The elongated recess is configured for receiving an elongated member therein along an entire length thereof. The at least one closure body is rotatably mounted on the main body. The elongated member may be positioned within the elongated recess via lateral movement when the at least one closure body is in a first rotational position relative to the main body. The elongated member may be retained within the elongated recess when the at least one closure body is moved away from the first rotational position toward a second rotational position relative to the main body.

An implant for repairing a joint between a first bone and a second bone includes a first section constructed of a substantially rigid material and a graft constructed of soft tissue having a first end and a second end. The first section has a first end surface configured for positioning against the first bone. The graft is configured for stabilizing the first section relative to the first bone. A first fastener is configured for mounting to the graft and the first section to anchor the graft to the first section. A second fastener is configured for mounting to the graft and the first bone to anchor the graft to the first bone.

A device comprising a trocar having a first end and comprising a cannulation and at least one fenestration proximal the first end; and a housing comprising a first port configured for the attachment of a first syringe and a second port configured for the attachment of a collection vessel, a first valve configured to selectively permit fluid flow through the cannulation of the trocar to the first port, and a second valve configured to selectively permit fluid flow through the cannulation of the trocar to the second port. The device allows the first syringe to draw up bone marrow in small volumes with high vacuum and then transfer the small draws into the collection vessel. The device may increase the recovery of desired cells residing in the bone marrow to be recovered during a bone marrow aspiration procedure.

An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a guide configured to be coupled generally perpendicular to the first bone proximate to the defect. The guide includes a body portion defining a plurality of excision passageways. The excision passageways each define a generally cylindrical core pathway configured to extend generally perpendicular to the first bone which partially overlaps with an adjacent generally cylindrical core pathway. A projection associated with each of the plurality of the generally cylindrical core pathways defines a truncated cylindrical excision site extending through a portion of the articular surface. Each truncated cylindrical excision site partially overlaps with at least one adjacent truncated cylindrical excision site.

A surgical saw for use in cutting bone. The saw may include a cutting member that is rotated about a drive pulley, an idler pulley, and first and second guide members. The guide members are in contact with an outer perimeter surface of a bone to be cut. The guide members may be moveable in opposite directions relative to the outer perimeter surface. In turn, the cutting member may be engaged with the bone in response to the movement of the guide members. The guide members may move along the outer perimeter surface of the bone until the cutting member has been moved through an entire cross-section of a bone to separate the bone. The saw may be initially inserted in a bore created in the bone to dispose the idler pulley at an opposite side of the bone as the drive pulley when commencing the cutting operation.

An arthroscopic cutting probe includes an outer sleeve having a longitudinal bore and an outer cutting window at its distal end. An inner sleeve is rotationally disposed in a bore of the outer sleeve, and the inner sleeve has a distal end, a proximal end, a longitudinal passageway, and an inner cutting window at its distal. An active electrode sleeve is disposed on an outer surface of the inner sleeve in a position opposed to the inner cutting window. Rotation of the inner sleeve relative to the outer sleeve causes the inner cutting window to rotate past the outer cutting window to resect tissue received through the cutting windows as they pass each other. Radiofrequency current can be applied to the active electrode to enhance tissue cutting then the cutting windows are being rotated or to able or cauterize tissue when the cutting windows are held stationary with the active electrode disposed through the outer cutting window.
