An orthopedic system to monitor a parameter related to the muscular-skeletal system is disclosed. The orthopedic system includes electronic circuitry, at least one sensor, and a computer to receive measurement data in real-time. The orthopedic system comprises a first plurality of shims of a first type, a second plurality of a second type, a measurement module, and the computer. The measurement module houses the electronic circuitry and at least one sensor. The measurement module is adapted to be used with the first plurality of shims and the second plurality of shims. The measurement module has a medial surface that differs from a lateral surface by shape, size, or contour.

A method and apparatus to autonomously analyze the surface area and alloy composition ratios of a metallic implant, such as an orthopedic implant, so that an optimal voltage for biofilm disruption can be selected and make treatment easier based at least in part upon the autonomous detection of a hydrogen evolution reaction threshold.

A method of coating a bone material in a container is provided. The method comprising adding the bone material to an opening of the container and sealing the opening of the container so that the bone material is disposed within an interior of the container; adding a liquid coating material to the interior of the container through an inlet of the container so as to coat at least a portion of the bone material with the liquid coating material; removing any excess coating material from the container from the interior through an outlet of the container; and removing the coated bone material from the container. A system of coating bone material under a sterilized environment is also provided.

Implantable electrochemical sensors for the pH measurement are herein described, comprising a working electrode and a reference electrode, in which both the working electrode and the reference electrode are integral part of an implantable orthopaedic medical device, as well as a method for their preparation and their use for monitoring the progression of bacterial infections in the implant sites of such orthopaedic medical devices.

A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has at least one distraction mechanism configured to increase or decrease a height between a first support structure and a second support structure. A tilt mechanism comprises the at least one distraction mechanism. The tilt mechanism couples through a first pivot point and a second pivot point and adjusts a tilt of the second support structure relative to the first support structure. In one embodiment, loading applied to the second support structure is distributed between the first pivot point and the second pivot point during operation of the surgical apparatus.

Hip replacement prosthesis are provided, comprising a femoral stem, a femoral head coupled to the femoral stem, and an acetabular assembly coupled to the femoral head, and a plurality of sensors coupled to at least of the femoral stem, femoral head, and acetabular assembly.

A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has three distraction mechanisms configured to increase or decrease a height between a first support structure and a second support structure. The tilt mechanism adjusts the tilt between the first support structure relative to the second support structure. The tilt mechanism of the surgical apparatus is adjusted from a first tilt to a second tilt to support a bone cut on one of the first or second bones.

A surgical apparatus comprising a first distraction mechanism, a second distraction mechanism, and a third distraction mechanism. The surgical apparatus is configured to be placed in a joint of the musculoskeletal system to precisely separate the first bone from the second bone to support one or more bone cuts for installing a prosthetic joint. The first distraction mechanism simultaneously changes a height of a first side and a second side of the joint. The change in height is equal on the first and second sides. The second distraction mechanism changes the height on the first side of the joint but not the second side. The third distraction mechanism changes the height of the second side of the joint but not the first side. The surgical apparatus further includes at least one module to measure loading applied by the joint to the surgical apparatus.
