Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure
Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure includes an impaction sensor and an impaction analyzer. The impaction sensor produces sensor data, in response to an impaction between an orthopaedic mallet and a surgical tool indicative of an initial impact and a secondary impact of the impaction. The impaction analyzer analyzes the sensor data to determine a temporal length between the initial and secondary impacts and determines whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length.
HYBRID PROSTHESIS INSTALLATION SYSTEMS AND METHODS
A system and method for inserting and aligning an acetabular cup in the human pelvic bone, including selectively combining aspects of a vibratory BMD3 and an axially-impacting BMD4, including initially utilizing BMD3 vibratory insertion to partially insert and perfectly align the acetabular cup into the pelvis, and subsequently switching to a BMD4 controlled impaction technique to apply specific quantifiable forces for full seating and insertion, wherein the proven advantages of the vibratory insertion prototype with the advantages of the controlled impaction prototype are combined in a single device.
TECHNOLOGIES FOR DETERMINING SEATING OF AN ORTHOPAEDIC IMPLANT DURING AN ORTHOPAEDIC SURGICAL PROCEDURE
Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure includes an impaction sensor and an impaction analyzer. The impaction sensor produces sensor data, in response to an impaction between an orthopaedic mallet and a surgical tool indicative of an initial impact and a secondary impact of the impaction.

METHOD AND APPARATUS FOR PREPARING AND IMPLANTATION OF MEDICAL IMPLANTS
An apparatus for implanting a medical implant into bone includes: an implant having at least one predetermined natural frequency; and an instrument, comprising: a housing; a coupler carried by the housing and configured to be mechanically connected to a medical implant; and a forcing mechanism carried by the housing and operable to apply a cyclic excitation force at the predetermined natural frequency.
Intervertebral fusion remote monitoring device
Disclosed is an invasive intervertebral fusion cage, the intervertebral fusion cage including: a vibration sensor; and a frame configured to support surrounding tissues used to create a bone fusion process; wherein the vibration sensor is integral with the frame in order to measure the mechanical vibrations the vibrations arising from the medium consisting of the frame, the surrounding tissues and/or the fusionned bone, and wherein the intervertebral fusion cage does not include a vibration excitation transducer. Also disclosed is a remote medical monitoring device including a receiver for receiving data from an intervertebral fusion cage, reflecting the mechanical vibrations of a medium and a calculator computing from the received data a medium indicator by: determining at least one vibration pattern of the received data; comparing the at least one vibration pattern with at least one reference model; generating a medium indicator in function of the comparing step.
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.
IN SITU SYSTEM AND METHOD FOR SENSING OR MONITORING
A system and method for quantitatively assessing a press fit value (and provide a mechanism to evaluate optimal quantitative values) of any implant/bone interface regardless the variables involved including bone site preparation, material properties of bone and implant, implant geometry and coefficient of friction of the implant-bone interface without requiring a visual positional assessment of a depth of insertion. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements.
ANATOMICAL LOCATOR TAGS AND USES
A system and method for providing a set of anatomical subdermal tags configured to form part of a local positioning system (in contrast to an operating room-wide global reference system) used in obscured visualization/localization of anatomical structures, locations, and components, as well as visualization/localization/orientation of implant(s) into referenced anatomical structures.

The impaction sensor produces sensor data, in response to an impaction between an orthopaedic mallet and a surgical tool indicative of an initial impact and a secondary impact of the impaction. The impaction analyzer analyzes the sensor data to determine a temporal length between the initial and secondary impacts and determines whether the orthopaedic implant is sufficiently seated into the bone based on the temporal length,
Force sense measurement in prosthesis installation
A system and method for allowing any surgeon, including those surgeons who perform a fewer number of a replacement procedure as compared to a more experienced surgeon who performs a greater number of procedures, to provide an improved likelihood of a favorable outcome approaching, if not exceeding, a likelihood of a favorable outcome as performed by a very experienced surgeon with the replacement procedure. Force sensing is included to aid in quantifying installation of an implant, particularly a cup into a pelvic bone.
