A method for placing an implant on a patient in a robotic surgical procedure using a robotic system. During the robotic surgical procedure, a navigation system tracks the patient. The navigation system also provides information to the robotic system to guide movement of a cutting tool to remove material from the patient such that a cut surface is created to receive the implant. The implant is then robotically placed on the cut surface.

Disclosed is a device for positioning a resurfacing prosthesis, including: a gripping and handling instrument for a main body of a resurfacing prosthesis; a connecting body, interposed between said gripping and handling instrument and said main body of said resurfacing prosthesis and suitable to connect them; a coupler which secures said connecting body to said main body, said coupler comprising: a plurality of bonding elements adapted to be interlocked, in an irremovable manner, in respective recesses provided in said connecting body; and a shear releaser, interposed between said main body of said resurfacing prosthesis and said connecting body, adapted to detach said connecting body from said main body. Other aspects are described and claimed.

The strength of bone implant attached to a bone is improved by using hybrid inserts which have stems and wings having bone ingrowth surface features and caps having outer surfaces of cured polymethyl methacrylate (PMMA). The stems and wings of the hybrid inserts are inserted into living bone and the bone implant is attached to the hybrid inserts with PMMA cement. Over time, the bone grows into the bone ingrowth surface features. The bone ingrowth strengthens the bonding of the hybrid inserts and the bone implant with the bone over time. The hybrid inserts increase the shear, tensile and torque strength of the bone implants. Bone inserts that do not have ingrowth surface features loosen over time.

A surgical implant and a method for the making the surgical implant is provided. The surgical implant includes various granules incorporated into an upper surface and a lower surface of a body portion thereof. The granules can be pressed into the upper surface and the lower surface via physical force using at least one mold portion. The physical force applied by the at least one mold portion can deform and/or extrude the upper surface and the lower surface to impregnate these surfaces with the granules. The granules can provide the implant with bioresorbable and/or mechanically-reinforced properties.

Devices and methods for restructure and stabilization of a fractured or weakened head of a bone are disclosed herein. A device includes a delivery catheter having a proximal end and a distal end, an inner void for passing at least one light sensitive liquid, and an inner lumen; an expandable member releasably engaging the distal end of the delivery catheter; and a light conducting fiber sized to pass through the inner lumen of the delivery catheter and into the expandable member. The expandable member moves from a deflated state to an inflated state when the light sensitive liquid is passed to the expandable member. When the light conducting fiber is in the expandable member, the light conducting fiber is able to disperse the light energy to initiate hardening of the light sensitive liquid within the expandable member to form a photodynamic implant.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.

The present invention relates to an apparatus, system and method for delivery of bone graft material in a patient's spine. The graft delivery device according to various embodiments delivers and disperses biologic material to a disc space and without withdrawal from the surgical site. In various embodiments, the graft delivery device includes an elongate hollow tube configured to receive bone graft material, a plunger adapted to extend in the elongate hollow tube and urge the bone graft material through the elongate hollow tube, and an injection device (such as a syringe) configured to contain the bone graft material therein and to connect to an open proximal end of the elongate hollow tube, to discharge the bone graft material from the first injection device into the elongate hollow tube.

Prostheses are described for stabilizing dysfunctional bone structures. The prostheses have proximal and distal ends, and an expandable mid-region disposed therebetween. The expandable mid-region includes a plurality of deflectable elongate members that are configured and adapted to transition from a compressed configuration to a deflected configuration when released from a deployment apparatus, whereby the plurality of deflectable elongate members deflects outwardly when the elongated member is inserted into a pilot opening of a dysfunctional bone structure, whereby the plurality of elongate members exerts a retaining force on the internal surface of the pilot opening and secures the elongated member in the pilot opening and, thereby, the dysfunctional bone structure.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.
