SYSTEM AND METHOD FOR MONITORING BY-IMPACTION ASSEMBLY BETWEEN A PROSTHETIC COMPONENT AND A SUPPORT MEMBER, AND SURGICAL KITS INCLUDING SUCH A SYSTEM

This system comprises: at least one vibrational sensor which is operable to produce data each time an impact application device applies an impact from a user to the prosthetic component during assembly between the prosthetic component and with the support member, the produced data representing acoustic vibrations generated in the air and/or material vibrations generated in the impact application device, an analysis unit which is configured both to calculate a frequency characterization of the vibrations for each impact applied by the impact application device to the prosthetic component, from the corresponding data produced by the at least one vibrational sensor, and to compare the frequency characterizations that are respectively calculated for successive impacts so as to provide at each of the successive impacts either a first indication when the assembly between the prosthetic component and the support member is not fully seated or a second indication when the assembly between the prosthetic component and the support member is fully seated, and a user interface which provides feedback to the user based on the first and second indications.

Device for assembly of ball heads and adapter sleeves as integrated component part of the package

A package for receiving an adapter sleeve for a hip endoprosthesis, the hip endoprosthesis comprising a ball head which has to be pushed onto the adapter sleeve with a defined pushing-on force. For simplification and secure fastening of the ball head on the adapter sleeve, it is proposed according to the invention that a device for the mounting of the ball head on the adapter sleeve is integrated in the package and this device comprises indicating elements which indicate that the defined pushing-on force has been reached when the ball head is pressed onto the adapter sleeve. Preferably the package has indicating elements.

Patient-specific spinal fusion cage and methods of making same

A method of determining disc space geometry with the use of an expandable trial having endplate-mapping capabilities. An expandable trial is inserted into the disc space and its height is adjusted to obtain the desired decompression and spinal alignment (which is typically confirmed with the use of CT or Fluoroscopic imaging). The endplate dome/geometry dome is then determined by one of the following three methods: a) direct imaging through the trial, b) balloon moldings filled with flowable in-situ fluid (for example, silicon, polyurethane, or PMMA) from superior/inferior endplates or c) light-based imaging through superior & inferior balloons.

ENHANCER ELEMENT

An enhancer element for use in intraoperative assessment of coupling of an orthopaedic implant to a bone is disclosed. The implant and the bone form an implant-bone system having a first set of vibrational modes with a first mode density in a frequency range, wherein the enhancer element is mechanically couplable to the orthopaedic implant to form an enhancer-implant-bone system having a second set of vibrational modes with a second mode density in the frequency range, wherein the second mode density is greater than the first mode density. The enhancer element is mechanically couplable to a first end of the orthopaedic implant so that it is adapted to receive impaction blows for introducing the implant to the bone. During a vibrational measurement, the vibrational response of the enhancer-implant-bone system provides information about the stiffness of the enhancer-implant-bone system.

SYSTEM AND METHOD FOR TRANSMITTING ORTHOPAEDIC IMPLANT DATA

A system and method for transmitting implant data includes an orthopaedic implant, a wireless receiver, and a processing circuit electrically coupled to the wireless receiver. The orthopaedic implant is configured to transmit implant identification data and implant sensor data to the wireless receiver in response to a power signal. The orthopedic implant may transfer the data over, for example, a wireless network. The processing circuit receives the implant identification data and the implant sensor data from the wireless receiver and is configured to retrieve patient-related data from a database based on the implant identification data. The processing circuit may also be configured to update a patient queue, assign a patient room to a patient, and/or transmit the patient-related data and the implant sensor data to a client machine located in the patient room.
