A device for forcefully inserting a surgical implant in a recipient bone by impaction, comprising an impactor (10) that exerts an impaction force on the implant and is associated with at least one sensor (12). The sensor (12) measures a value from among the exerted impaction force and the deformation of the impactor (10) and provides a measurement signal representing the temporal variation of said value during an impact. The sensor (12) is connected to a processing unit (30) that is configured to compute, on the basis of the temporal variation of said value during the impact, an indicator representing the level of contact between the implant and the recipient bone. The indicator corresponds to the duration separating the instant corresponding to the first maximum amplitude peak of the measurement signal from the instant corresponding to the second maximum amplitude peak of the measurement signal. The implant can be a femoral rod (2).

Systems, instruments, tools and methods for facilitating the removal of a knee or hip implants and other bone implants.

An implant insertion tool for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes a metallic elongated shaft, a removable polymeric grip, and a locking nut to secure the grip to the elongated shaft. Such a modular design allows the implant insertion tool to be dissembled prior to sterilization.

A reverse shoulder system can include, for example, a glenoid baseplate comprising a longitudinal axis, the glenoid baseplate further including a stem and a central channel within a sidewall of the stem. The stem can include a longitudinal axis. The longitudinal axis of the glenoid baseplate can be angled with respect to the longitudinal axis of the stem, wherein the longitudinal axis of the glenoid baseplate is not perpendicular with respect to the longitudinal axis of the stem. Other components including a glenosphere, tools, and methods of use are also disclosed.

Disclosed herein is a toe implant for replacing a portion of a human toe joint, as well as a related kit, surgical method, and method of manufacturing. Specifically, the toe implant may include a bearing member having a curved interface surface and a fixation member coupled to the bearing member. The fixation member may include a first portion having a non-porous barrier, and a tapered second portion.

An improved method of fusing the sacroiliac joint and tools for accomplishing the same is disclosed. In one embodiment, the present invention is a method that uses an intra-articular joint fusion device for connecting the sacrum and ilium that includes creating a first incision in the patient's skin proximal to the patient's sacroiliac joint, inserting a surgical channel tool into the incision from the patient's posterior, creating a void in the sacroiliac joint, inserting a fusion implant into the void, the fusion implant having at least one fixation element for engagement with bone tissue in the articular surfaces of the sacrum and the ilium, and driving the fusion implant into the void such that the at least one fixation element engages with bone tissue in an articular surface of at least one of the sacrum and ilium, and the fusion implant fixes relative positions of the sacrum and ilium.

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.

An orthopaedic surgical instrument may include an elongated body with a proximal end and distal end. A clamp lever may be pivotally coupled to the proximal end of the elongated body. The clamp lever may be moveable between a locked position and an unlocked position. A biasing element may be configured to bias the clamp lever to the locked position.

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.

The present invention concerns a cage holder including an elongated body comprising a proximal end and a distal end, the elongated body extending from the proximal end to the distal end. The cage holder is characterized in that it further includes means for transferring energy centrally from the proximal end to the distal end through the elongated body.
