Patent number: 11224523Abstract: Orthopedic guide, and methods of using the guide, for alignment of bone under fluoroscopic imaging. In an exemplary embodiment, the guide may include a radiopaque rod, a radiolucent carrier, and a radiopaque indicator held by the carrier. The rod and the indicator may be parallel to the same plane, and may form an angle between one another of less than 90 degrees when projected orthogonally onto the plane. The rod may be configured to be aligned with an axis defined by one or more bones of the leg, and the indicator aligned with a joint of the leg, in an anterior-posterior, fluoroscopic view of the leg. The angle formed between the rod and the indicator may correspond to an anatomic orientation of the axis and the joint relative to one another in a frontal plane of the leg.Type: GrantFiled: January 6, 2020Date of Patent: January 18, 2022Assignee: Acumed LLCInventors: Joshua P. Federspiel, Bharadwaj Ananthan, Amir M. Matityahu, David W. Vanvleet

Patent number: 10743923Abstract: System and method for fixing a distal femur having a Hoffa fracture. The system may comprise a main plate, an outrigger plate, and a coupling member that mounts the outrigger plate to the main plate. In an exemplary method, an elongated body portion of the main plate may be secured to a shaft region of the distal femur, and a wider head portion of the main plate may be secured to an end region of the distal femur. The outrigger plate may be mounted on the head portion of the main plate, and an arm of the outrigger plate may be fastened to a condylar fragment of the femur with one or more fasteners, such that the outrigger plate spans and stabilizes the Hoffa fracture.Type: GrantFiled: October 3, 2017Date of Patent: August 18, 2020Assignee: Acumed LLCInventors: Bharadwaj Ananthan, Thomas R. Lyon, Amir Meir Matityahu, Andrew Howard Schmidt

Patent number: 10675072Abstract: Apparatus and method for fixing a bone using a plate and a coupler that are connected to one another with flexible members. The plate may be configured to be attached to a shaft region of a bone. The coupler may be configured to be disposed on an end region of the bone, and may define a bore and an aperture. The flexible members may include a first flexible member and a second flexible member, each including a wire or cable. The first flexible member may be configured to extend from the plate, through the bore, and back to the plate. The second flexible member may be configured to extend from the plate to the coupler on a path that approaches the coupler transverse to a line that is parallel to the bore. The apparatus and method may be used to stabilize the greater trochanter of a femur.Type: GrantFiled: January 2, 2018Date of Patent: June 9, 2020Assignee: Acumed LLCInventors: Bharadwaj Ananthan, Amir Meir Matityahu, Thomas R. Lyon, Andrew Howard Schmidt, David William Vanvleet

Patent number: 10675071Abstract: Systems and methods for bone fixation using a plate straddled by a retainer. In an exemplary system, the plate may be an elongated plate configured to be disposed longitudinally on a bone. The retainer may have a body interconnecting a pair of mounting regions. The body may define a recess, and each mounting region may define a first aperture and a second aperture. The retainer may be configured to be mated with the plate to position a section of the plate in the recess such that the retainer straddles the plate. The first apertures may be configured to define through-axes that are tangential to the bone, to enable use with a line including wire and/or cable, and each second aperture may be configured to define a through-axis that extends through opposite sides of the bone while avoiding a medullary canal thereof, to enable use with a threaded fastener.Type: GrantFiled: October 5, 2017Date of Patent: June 9, 2020Assignee: Acumed LLCInventors: Bharadwaj Ananthan, Matthew Peter Gephart, Thomas R.
