A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

A method for preparing a first bone for receiving a prosthesis. The method includes coupling a revision alignment member to a template; positioning an offset alignment bushing relative to the revision alignment member; positioning the offset alignment bushing at the first bone such that an intramedullary member seated in the first bone extends through a passage defined by the offset alignment bushing; replacing the offset alignment bushing with a first bone cutting bushing; cutting the first bone using the first bone cutting bushing as a guide; replacing the first bone cutting bushing with an offset second bone cutting bushing; providing the second bone cutting bushing with a rotational orientation corresponding to a rotational orientation of the offset alignment bushing; and cutting the first bone using the offset second bone cutting bushing as a guide to prepare the bone to receive an offset prosthesis adapter.

Implant includes a body and a utile feature, for example, a smooth articulating surface. A transverse rail stem system with a plurality of rails is provided, spaced apart from the utile feature, which is adapted for transverse insertion into a bodily substrate, for example, resected bone. A surgical templatefor example, to assist in sawing, drilling with a drill bit and drill guide, and broaching with a broachalong with such bone removal tools can help prepare the bone for receipt of the implant.

A method of fusing a dysfunctional sacroiliac joint with an additively manufactured joint implant comprising a plurality of openings extending from a top surface into an inner portion of the joint implant via a plurality of channels, and an orifice extending from an exterior surface of the proximal end into the inner portion, wherein the orifice is in fluid communication with the plurality of channels via the inner portion; delivering the joint implant into the sacroiliac joint space through an access region and injecting an amount of biocompatible material at an initial stage of an injection process into the inner portion via the orifice and with a delivery tool; and, at a subsequent stage of the injection process the amount of biocompatible material moves from the inner portion through the plurality of channel via a second path and into the sacroiliac joint space immediately adjacent a top surface.

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

Tibial resection systems and methods for use in a uni- or bi-cruciate retaining knee replacement procedure are disclosed. A tibial resection system can include a tibial block, an alignment guide, and a tibial implant template. The tibial block can be coupled to an anterior side of a tibia and longitudinally extend from a proximal end portion to a distal end portion. The alignment guide can be coupled to the proximal end portion of the tibial block and can include one or more drill guides and a drill guide adjustment mechanism. The tibial implant template can be engaged with the drill guide adjustment mechanism, such that rotational movement of the tibial implant template can adjust an axial direction of the one or more drill guides. An outer profile of the tibial implant template can be selected to substantially match an outer profile of a tibial prosthesis to be implanted.

A method of surgically preparing a proximal end of a tibia includes inserting an intramedullary orthopaedic surgical instrument into a medullary canal of the tibia, securing an attachment device to the intramedullary orthopaedic surgical instrument, attaching a cutting block to the attachment device, resecting the proximal end of the tibia using the cutting block to form a surgically-prepared surface, positioning a tibial base trial on the surgically-prepared surface, and inserting a keel punch through a slot defined in the tibial base trial and into the surgically-prepared surface of the tibia.

A guide assembly for facilitating placement of a fixation member within a medullary canal of a radius is provided. According to one embodiment, a guide assembly includes a guide fastener configured to attach to a fixation member and a guide member configured to receive the guide fastener such that the guide member is secured to the fixation member. The guide assembly also includes an interchangeable distal guide member configured to engage and be disengaged from the guide member. The distal guide member defines a plurality of fastener guide openings for guiding respective fasteners through a plurality of fastener openings defined in the fixation member.

A contact portion, provided in an exposed surface of the treating section, treats a treated object by a transmitted ultrasonic vibration while intruding into the treated object toward an intruding direction from a state being in contact with the treated object. An index portion is disposed on an anti-intruding direction side with respect to the contact portion in the exposed surface. The index portion becomes an index indicating an intruding amount of the contact portion into the treated object toward the intruding direction. The index portion includes index surfaces arranged in the intruding direction, and each of the index surfaces has an angle relative to the intruding direction which is different from the angle of the adjacent index surface.
