Publication number: 20200113604Abstract: A vertebral column correction system for correcting a spinal deformity without fusing the joint segments is disclosed. The vertebral column correction system may have first and second vertebral anchors secured to first and second vertebrae. The vertebral column correction system may further comprise one or more intermediate vertebral anchors secured to vertebrae between the first and second vertebrae. A connection member may be disposed within a head portion of the vertebral anchors. At least a portion of the connection member may be a flexible member, such as a flexible cord, configured for tensioning between at least two vertebral anchors for providing a desired amount of tension to apply a correctional force to the spinal column. A spring member, or other tensioning member, may maintain the tension of the connection member.Type: ApplicationFiled: December 13, 2019Publication date: April 16, 2020Inventor: Hugh D. Hestad

Publication number: 20200113606Abstract: Devices for retracting tissue during a minimally-invasive, posterior spinal fusion procedure include a blade positionable along a passageway device connected to a connecting element implanted in a vertebra of the spine, such that the blade covers at least a portion of a longitudinal opening of the passageway device. The blade may be coupled to the passageway device by receiving the passageway device with a receiving portion. Systems for displacing the vertebrae of the spine include first and second extenders, the distal ends of each of which are configured to engage the connecting elements. Each extender may include a shaft configured to be securely engaged within a cage of the respective connecting element. The devices and systems of the present invention may be used in connection with an interbody fusion technique performed through an opening extending between the passageway devices, and an intermediate retractor blade may provide additional tissue retraction.Type: ApplicationFiled: December 16, 2019Publication date: April 16, 2020Inventors: Abram Reitblat, Steven F. Krause, Douglas G. Pedrick, David Talijan, Erika Corbin

Publication number: 20200113609Abstract: A femoral intramedullary device is capable of treating a variety of femoral bone fractures. The device includes an intramedullary nail capable of antegrade or retrograde insertion into the femur and having a shank long enough to extend into the shaft of the long bone and reach the corresponding distal area or proximal area and sockets located intermediate the ends of the shank for receiving anchoring pins or screws extended transversely or radially from the shaft of the long bone. The intramedullary nail is placed in the intramedullary canal of a portion of the bone and the screws are fixed in the radial sockets or receivers at the level of the femoral neck to provide mechanical support across the bone. Transverse screws are placed through the transverse sockets to provide additional support and secure the nail within the femur.Type: ApplicationFiled: October 15, 2019Publication date: April 16, 2020Inventors: Arun Aneja, Lorenzo Deveza, Shea Comadoll, Boshen Liu
