The invention comprises a medical implant system with implant having a fastener hole for a fastener and further including a fusion screw, positioned to avoid interference with the implant fastener. The medical implant system also includes a guide that is mounted in the fastener hole and from an edge of the implant which provides for defined adjustability for angulation, and optionally depth, to allow for placement of the fusion screw so as to avoid impingement with the implant and the fasteners that secure it in place. The invention also relates to a method of surgery using the system.

A computer-aided method of pre-operative planning of hip joint replacement is provided for establishing, from patient-specific images, femoral and acetabular implant sizes and cut planes. Image slices of a patient's hip joint are obtained. Coordinate positions of selected femur and acetabulum points (e.g., femoral head center, major trochanter midpoint, femoral shaft midpoint, acetabular rim high points and lowest point) in the images are marked, which allows the planning tool to perform a best fit analysis to offer a range of suitable implant and surgical cut plane parameters for selection by a surgeon. Patient-specific surgical jigs can then be constructed for the proximal femur and acetabulum of the hip joint corresponding to a surgeon selection between standard, mini, short-stem, and resurfacing hip replacement components and in accord with the surgeon-selected parameters.

A system for targeting a feature on a surgical device, includes a shape sensing element coupled to an interrogator and operable to provide information to related to said portion's position in a reference frame in communication with the targeted feature. The interrogator is operable to poll the shape sensing element for information related to said portion's position in the reference frame. A surgical tool is coupled to the targeting system in communication with the shape sensing element. The data processor is operable to communicate with the interrogator to output position information of the portion of the shape sensing element with respect to a calibrated position, defined as the position of the portion of the shape sensing element in the reference frame when the guide axis is aligned to the targeted feature. A display provides the user visual information comparing the position of the tool to the targeted feature.

A computer program element and a device are provided for processing a 2D projection image generated during a procedure of fracture treatment of a bone. The computer program element comprises sets of instructions for detecting the reference body in the 2D projection image, detecting at least one element out of the group consisting of an instrument, an implant and an anatomical structure in the 2D projection image, and identifying a current state of the element, determining a state of progress of the procedure of fracture treatment, and providing information regarding steps to be performed next.

A tibial suprapatellar entry portal system (1) comprising a sleeve (2), an anchor pin (200), and a trocar (40).

An assembling kit for installing intramedullary nail is provided, which is suitable for assisting in fixing a securing member to at least one fixing hole of an intramedullary nail placed in a bone. The assembling kit for installing intramedullary nail includes a drilling member, a guiding member and a hole-reaming member. The drilling member is configured to form an opening on a surface of the bone and has a tapping portion. A diameter of the tapping portion is greater than a diameter of the fixing hole. The guiding member is configured to be put into the fixing hole along a central axis. The hole-reaming member is sleeved on the guiding member and is configured to ream the opening to form a mounting hole. The hole-reaming member has a reaming portion, and a diameter of the reaming portion is greater than the diameter of the tapping portion.

An orthopedic implant is specifically configured for use in osteotomies, in which part of the implant extends into an intramedullary portion of a first bone segment and a plate portion is external to the cortical surface of an adjacent bone segment to fix the segments to allow them to fuse. The body of the implant has a first end and a second end where the end which is inserted into the bone has a chamfer and a through hole having a hole axis optionally at an oblique angle to the longitudinal axis of the implant, and which can receive a screw, peg or pin. The second end of the implant includes a plate portion with at least two offset screws.

Alignment guide systems, fixation guide devices, and methods for positioning and inserting an intramedullary nail are disclosed. The alignment guide system includes a targeting guide with a first end and a second end, an alignment wire rotatably engaging a second end of the targeting guide, and a guide sleeve insert engaging an opening in the first end of the targeting guide. The fixation guide device including a frame including a first end and a second end, a compression device slidingly coupled to the first end of the frame, and the intramedullary nail secured to a nail attachment apparatus of the frame. A method of inserting an intramedullary nail into two bones for fixation of the two bones is also disclosed.

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.

An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.
