Abstract: Provided is a novel physical therapy system and device that can be manually operated by a post-operative patient without the need of professional on site assistance, wherein the degree of movement of the limb or joint of interest is measured and recorded so as to provide a record of the progress of the prescribed post-operative therapy for immediate feedback to the patient as well as for long term data recordation for the therapist or physician.

Abstract: Provided is an adjustable spacing device configured to be placed between the spinous processes of at least two adjacent vertebrae, the device including a transverse member and at least one adjustable transverse member, which connect two parallel longitudinal legs one to the other and a method of using the device to treat spinal stenosis by restricting extension and allowing normal flexion of adjacent vertebrae relative one to the other.

Abstract: A novel cross-connector assembly for interconnecting first and second bracing members or rods, one to the other. The cross-connector assembly is capable of multi-directional articulation in three dimensions, length, azimuth, and elevation and is also capable of having one end rotated along its longitudinal axis in relation to the other end so as to custom fit and securely connect the assembly to two opposing bracing members or rods. Also provided is a kit including the device and ancillary instrumentation to facilitate the method of the present invention.

Abstract: Provided is a novel hip replacement implant system that includes a ball assembly having a ball trunnion, the ball assembly being configured as a replacement for the head of the femur and capable of being secured by the ball assembly trunnion to a calcar implant element that can be securely seated in the calcar bone of the femoral neck, thus maintaining the load transfer function of the calcar bone of the femoral neck. A method of using the device is also provided.

Abstract: A device and method enables surgeon to bilaterally secure two vertebrae together in a stable and strong manner. A kit includes the device and ancillary instrumentation to facilitate the method of the present invention.

Abstract: Provided is a device for attachment to tubular connections that serves to ensure the securing of the connection and the avoidance of inadvertent disconnections. Also provided is an endotracheal tube having a releasable locking device component that serves to ensure security of the connection of the endotracheal tube to a breathing system. Also provided is a breathing system having a releasable locking device component that when employed ensures the security of the connection.
