A surgical system is provided that includes a body extending along a longitudinal axis. A first member is rotatably positioned within the body and includes a first threaded surface. A second member is positioned within the body and includes a second threaded surface that engages the first threaded surface. The second member is non-rotatable relative to the body. A third member is positioned within the first member. An inflatable bone tamp includes an outer shaft coupled to the body, a balloon coupled to the outer shaft and an inner shaft coupled to the third member and the balloon. The first member is rotatable relative to the body to translate the third member along the longitudinal axis to move the balloon from a first length to a second length. Kits and methods are disclosed.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A device for delivering a material to an orthopedic target site is disclosed. The device can be used to deliver bone cement to an intra-vertebral site. The device can have a pusher rod within a tube. The tube can be loaded with the bone cement distal to the pusher rod. The pusher rod can have varying rigidity along the length of the pusher rod. The tube and pusher rod can navigate tortuous pathways from a percutaneous or transcutaneous insertion en route to the target site or to improve extracorporeal ergonomics. Methods for using the same are also disclosed.

A bone void plug includes a plug body that extends along a longitudinal axis between a proximal face and a distal opening and a recessed opening that extends from the distal opening toward the proximal face. The recessed opening is configured to receive a bone void filler.

Methods for using the same are also disclosed.

Methods and systems are provided for robotic assisted surgery. A robotic system includes a localizer, a surgical robotic manipulator, an end effector configured to be removably coupled to the manipulator, and a controller. The controller is configured to receive signals from the localizer, determine a final position of a cavity creation tool used to penetrate a portion of a patient's anatomy based on the signals received from the localizer, and determine an implant insertion path for an implant to be inserted into a final implant position within the portion of the patient's anatomy, wherein the final implant position corresponds to the final position of the cavity creation tool. The controller is also configured to move the end effector with the implant coupled thereto such that the implant moves along the implant insertion path, and terminate the movement of the end effector when the implant reaches the final implant position.

The invention relates to a method of creating a curvilinear cavity within a vertebral body or other body structure. The invention also relates to devices that may be used to perform the steps to create the curvilinear cavity. One such device is a curved drill including a lever and cam sub assembly. The curved drill can include a spring assembly that controls the curvature of the drill. The lever and cam sub assembly can be provided to allow tension to be reduced in the spring assembly.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A spinal implant comprises a body including an inner surface that defines a cavity. The inner surface includes a baffle. The body is disposable between a contracted configuration and an in vivo expandable configuration. Systems and methods are disclosed.

Instruments and associated methods are disclosed for treating joints, and particularly bone tissue. In general, the embodiments relate to instruments and associated methods for the surgical treatment of a joint, and particularly to a subchondral bone defect at that joint region. More specifically, the embodiments relate to instruments that allow fast, easy, precise, and controllable subchondral delivery to, or removal of materials from, a bone joint being treated.
