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.

A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.

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.

An inclination guide for use with an implant insertion tool during a surgical procedure includes a unitary body having a clip configured to be coupled to a mounting surface of the implant insertion tool, an elongated riser extending from the clip, and an elongated indicator extending from the elongated riser to a distal end. Such a design allows for an inexpensive and lightweight inclination guide that may be easily and quickly adjusted after assembly.

A surgical guide system includes a shell trial having a convex side configured to engage an acetabulum, a concave side forming a cavity therein, and windows extending through the convex and concave sides for viewing bone. The system further includes a liner trial having a convex side configured to be received within the cavity of the concave side of the shell trial, and a concave side with recessed hole guides there, wherein more than one of the hole guides align with the windows of the shell trial when the liner trial is received therein. The system further includes an acetabular cup implant having a convex side configured to engage an acetabulum, a concave side, and a thickness extending between the concave and convex sides, the concave side defining a cavity configured to receive the liner trial.

An acetabular cup prosthesis comprising: an inner cup surface and an outer cup surface, said inner cup surface meeting said outer cup surface at a rim of said cup, wherein said inner cup surface, said outer cup surface or both said inner cup surface and said outer cup surface comprises an engagement formation located proximal to said rim, said engagement formation extending around at least a portion of the circumference of the cup; and a Sip member comprising an engagement formation configured to cooperate with the engagement formation of the cup.

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,

Apparatus for measuring size of a cup for hip arthroplasty according to the present disclosure includes a scale plate marked with a scale to measure size, a first leg portion fixed to one end of the scale plate, and a second leg portion slidably moved relatively to the first leg portion along the scale plate, in which the second leg portion is marked with reading line. First and second jaws for contacting the cup are provided with 180° rotational symmetry on ends of the first and second leg portions, respectively. Central portions of the first and second jaws are bent to protrude in direction in which the first and second leg portions are farther away from each other, so that when contacting inner diameter of the cup, the jaws form one-point contact with the cup, and when contacting outer diameter of the cup, form two-point contact with the cup.

A device for separating a hard acetabular liner (e.g., metal, ceramic, etc.) positioned in an acetabular shell, the device including an elongated member having a proximal and distal end, an engagement structure positioned at the proximal end of the elongated member. The engagement structure includes a first portion having a curved outer surface, a first end-face aligned substantially perpendicular to the longitudinal axis of the device, and an inner surface extending from the first end-face, the first portion structured to fit at least partially into a scallop-shaped recess on a peripheral top surface of the acetabular shell, and further includes a second portion separated from the first portion by an opening, structured to accept the top surface of the acetabular liner, and including an outer surface extending a second length from the proximal end of the elongated member, structured to contact the top surface of the acetabular shell.

An end effector for a computer-assisted surgical system includes a mount configured to be coupled to an arm and a housing coupled to the mount and configured to interchangeably support a first operating member and a second operating member. When the housing supports the first operating member, the housing is configured to prevent translation of the first operating member relative to the mount. When the housing supports the second operating member, the housing is configured to allow translation of the second operating member relative to the mount along a first axis.
