An intervertebral fusion cage having a plate pivotally attached thereto. The plate and cage are pivotally coupled but move independently of each other. The plate is made up of two smaller plate halves: a superior plate half and an inferior plate half Both plate halves form the larger plate. The plates are joined using a cross pin that provides a pivot point about which the plate halves rotate. The same pin also joins the plate halves to the cage, thus allowing the plate halves to pivot about the cage. It is believed that the device of the present invention will reduce the difficulties in placing a lateral plate down a port and manipulating it into position. Mating the plate to the cage will reduce the chances of micromotion and improve fusion rate, resulting in improved patient outcomes.

Sensor-based shoulder system and method

Номер: US20210153947A1
Принадлежит: Zimmer Inc

The subject matter includes a system and method for providing graphical feedback visualizing forces within a joint through a range of motion of the joint. The method can comprise receiving position data, receiving force data, and generating a graphical representation based on the position data and the force data. The receiving position data can include data for at least one bone of a joint while the at least one bone is moved through a range of motion (ROM). The receiving force data can occur concurrently to receiving the position data and using one or more processors, the force data can be collected from at least one force sensor embedded within a trial prosthesis in the joint. The graphical representation can illustrate changes in the force data versus locations of the bone as it moved through the ROM.
