  • TECHNOLOGIES FOR DETERMINING SEATING OF AN ORTHOPAEDIC IMPLANT DURING AN ORTHOPAEDIC SURGICAL PROCEDURE
    Publication number: 20230181336
    Abstract: 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.

  • Technologies for determining seating of an orthopaedic implant during an orthopaedic surgical procedure
    Patent number: 11596528
    Abstract: 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.

  • ORTHOPAEDIC SURGICAL INSTRUMENT FOR TOTAL HIP ARTHROPLASTY AND ASSOCIATED ORTHOPAEDIC SURGICAL METHOD OF USE
    Publication number: 20220104952
    Abstract: An orthopaedic surgical instrument includes an assembly collar having a cavity extending between a superior opening and an inferior opening. The cavity is sized to receive a tapered trunnion of an implanted femoral stem. A bore extends between an inferior end and a superior end of the assembly collar and is configured to align with an implant bore formed in the implanted femoral stem. The bore and the implant bore are configured to receive a fastener to secure the assembly collar to the implanted femoral stem. A method of utilizing the orthopaedic surgical instrument is also contemplated.
