Abstract
A surgical device for joint replacement surgery includes an intraoperative joint head having a stem attachment structure where the stem attachment structure may be removably attachable to a stem and a force sensor housed by the joint head for measuring in vivo forces during surgery. The in vivo forces may be generated by one or more of tension provided by soft tissue, load application during surgery, limb movement during surgery, and a combination thereof. Also, the joint head may provide a cavity where the stem attachment structure houses the force sensor and may be removably insertable in the joint head cavity. A method of performing joint replacement surgery includes installing an intraoperative joint head having a force sensor housed by the joint head and a stem attachment structure, the stem attachment structure being removably attachable to a stem, measuring joint forces, and adjusting an implant parameter based on the measured joint forces.
