The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine and methods for inserting said discs. The intervertebral prosthetic discs are provided with connections for facilitating implantation and removal and features which enhance primary and secondary stability over time.

The present invention provides a technique for percutaneous intramedullary fixation. A protective outer sheath is provided for internal fixation of the proximal tibia. Additionally, a unique intramedullary plate is provided that is adapted for percutaneous insertion into the intramedullary canal of a long bone. A plate holder is also provided that may be utilized through the outer sheath to drive and position a fixation plate within the intramedullary canal.

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.

Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed. Some of the methods include inserting a guide pin into the glenoid of the patient, advancing a reciprocating surgical rasp over the guide pin, reciprocating the surgical rasp so as to abrade bone tissue to form a cavity shaped to receive the glenoid component, and implanting the glenoid component in the cavity.

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.

Implementations described and claimed herein provide a spinal facet cage implant for implantation in a spinal facet joint. In one implementation, the implant includes a distal leading end, a proximal trailing end, a first face, and a second face. The distal leading end has a distal surface generally opposite a proximal surface of the proximal trailing end. The first face has a first surface that is generally parallel with a second surface of the second face. The first and second faces extend between the distal leading end and the proximal trailing end. The first and second surfaces having one or more textured features adapted to provide friction with the spinal facet joint. One or more windows are defined in the first and/or second surfaces, and one or more side windows are defined in the first and/or second side surfaces.

A distally expanding facet implant with integrated plate and delivery device for distracting a cervical intervertebral facet joint to treat symptoms of degenerative processes of the cervical spine, including widening the intervertebral space and foramina while maintaining or restoring natural lordosis and preventing kyphosis. The distally expanding facet implant with integrated plate and delivery device generally includes opposed plates having distal and proximal ends, a diverting member having a stationary component and a moveable component comprising a diverting nut with a substantially fusiform cross-section between the plates, and a driving member comprising an elongated screw rotationally coupled with the moveable component. Rotation of the screw causes an engagement surface of the diverting nut to slide against a complementary engagement surface of the stationary component. The dimension of the nut present between the distal ends of the plates increases as the surfaces slide against each other causing the distal ends to divert without diverting the proximal ends. Deployed within a facet joint, the implant produces distraction of the facet joint and widening of the intervertebral spacing and foramina while maintaining natural lordosis and preventing kyphosis.

A medical device for preparing an elongated bone, such as a proximal femoral bone, for receiving an implant includes a patient-specific femoral guide and an elongated alignment element. The femoral guide has a patient-specific three-dimensional bone-engaging surface configured according to a preoperative plan based on a three-dimensional image model of the femoral bone to mate complementarily with the surface of the proximal femoral bone extending between the greater trochanter, the femoral neck and the femoral shaft of the proximal femur. The femoral guide includes a first guide end forming a planar guide configured for guiding a neck resection. The alignment member can be removably attached to the femoral guide and defines a reference axis for guiding a cutting tool into the femoral bone through a resected surface of the femoral neck.

Embodiments of instrumentation and methods are provided for the insertion of intervertebral disc prosthesis. The instrumentation of the embodiments comprises a guide comprising at least two lateral faces, at least one upper plate, at least one lower plate, at least one retainer, a cage defining an insertion axis for the prosthesis, and an angle adjuster adapted to adjust an angle formed by the insertion axis and an antero-posterior sagittal axis; and at least one separator sized to maintain a gap between the upper vertebra and the lower vertebra. Methods for implanting a prosthesis using the disclosed instrumentation comprise implanting a pin in the median sagittal axis of a vertebrae; measuring the dimensions of the intervertebral space; choosing the prosthesis; choosing the guide; adjusting the angle adjuster; positioning the guide adjacent to the intervertebral space; inserting the prosthesis into the guide; and inserting the prosthesis into the intervertebral space.

A spinal joint distraction system is disclosed and may include a driver assembly with a tubular shaft, a pair of implant holder arms, an implant distractor, an internal actuator, and a distractor knob, the system also including a delivery device with a tubular shaft, a receiving assembly, and a pair of forks, where the delivery device is adapted for slidable insertion of the driver assembly, the system also including an implant, a chisel, and an injector. Several embodiments of an implant are disclosed as well a method of placing an implant.
