Patent number: 10786283Abstract: A skeletal fixation apparatus may include two or more bodies that are attached to two or more screws that have been inserted into vertebral bodies associated with a patient. The apparatus may also include two or more cylindrical members that are attached to the bodies to control the movement or alignment of the bodies when the skeletal fixation apparatus is being installed in the patient. The apparatus may further include a rod that includes a first curvature and a second curvature. The first curvature may be different than the second curvature and may be based on a medical diagnosis associated with stabilizing the vertebral bodies. The second curvature may enable the bodies to be immovably fastened to the rod in a manner that precludes the cylindrical members from contacting each other or causing a false torque condition to exist when the skeletal fixation apparatus is installed in the patient.Type: GrantFiled: August 1, 2013Date of Patent: September 29, 2020Assignee: MUSC Foundation for Research DevelopmentInventors: Bruce M.
