Patent number: 11357550Abstract: The present disclosure includes a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.Type: GrantFiled: May 24, 2021Date of Patent: June 14, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Thomas Keyer, Joseph Capozzoli, Eric McDivitt

Patent number: 11311317Abstract: A spinal fixation device for securing two stabilizing rods to bone has a threaded shaft, a first rod coupling head connected to the threaded shaft and a secondary rod coupling head. The first rod coupling head has a side wall and a cavity with an open top for receiving a rod. In a neutral position of the first rod coupling head, the first rod coupling head extends symmetrically around the longitudinal axis of the threaded shaft. The second rod coupling head is rotatably connected to the first rod coupling head, around an axis of rotation. The axis of rotation is disposed at an angle that is not perpendicular to the longitudinal axis of the threaded shaft when the first rod coupling head is in the neutral position. This allows for two rods to be manipulated independently through different axis planes at any single point of bony fixation.Type: GrantFiled: September 25, 2019Date of Patent: April 26, 2022Inventor: Stelios Koutsoumbelis
