Publication number: 20230085069Abstract: Modular surgical instruments and related methods are disclosed herein, e.g., for performing rod reduction, derotation, and/or set screw insertion during spinal surgery. An exemplary system can include an instrument body configured to couple to a bone anchor assembly to provide a modular platform for carrying out various steps of a surgical procedure. For example, the instrument body can receive a reduction instrument therethrough for reducing a spinal rod into the bone anchor assembly. A derotation instrument can be attached to the reduction instrument for performing derotation maneuvers or applying other manipulation forces. A modular driver or handle adapter can be attached to the reduction instrument and/or to the derotation instrument to facilitate rod reduction. Any of the instrument body, the reduction instrument, and the derotation instrument can include a working channel therethrough.Type: ApplicationFiled: August 9, 2022Publication date: March 16, 2023Applicants: Medos International Sarl, Medos International SarlInventors: Christopher Mickiewicz, Mark Gracia, Thomas Runco, Sarah Batchelor, Richard Fournier

Publication number: 20220395295Abstract: Bottom-loading bone anchor assemblies and components thereof are disclosed that have a reduced profile and can be utilized with bone screws of various size. Bone anchor assemblies of the present disclosure can include a receiver member, a drag retaining ring, and a shank. The retaining ring and shank can be inserted proximally into a bore of the receiver member. The drag ring can have a base and a walled portion extending proximally therefrom. The drag retaining ring can be disposed in a groove of the receiver member with the base forming a seat for the shank head that can hold the shank within the receiver. The walled portion of the drag retaining ring can impart a drag force on the shank head seated in the base to prevent unintended movement between the shank and the receiver member.Type: ApplicationFiled: August 10, 2022Publication date: December 15, 2022Inventors: Ellen Roberts, Eric Biester, Christopher Mickiewicz

Publication number: 20220280202Abstract: The present disclosure generally relates to pedicle screws that can selectively lock polyaxial motion of a receiver head with a locking cap. The locking cap can allow locking of the polyaxial motion of the receiver member relative to the spherical head of the bone shank without having a rod placed in the rod slot of the receiver member. This can enable placement of the head of the pedicle screw in a desired position and orientation, locking the head in the desired position and orientation, and performing a maneuver, such as derotation, without a rod in place or any extra motion between the receiver member and the bone shank. In some embodiments, actuation of the locking cap can be achieved by rotating the locking cap relative to the receiver member, where rotation of the locking cap causes corresponding axial translation of the locking cap relative to the receiver member.Type: ApplicationFiled: March 2, 2022Publication date: September 8, 2022Inventors: Christopher Mickiewicz, Alec Manson, Ellen Wasserbauer

Publication number: 20220280201Abstract: Bone anchor assemblies are disclosed herein that provide for a single bone anchor assembly that can be utilized across a range of spinal surgical procedures, reduce manufacturing burden and cost, and provide for greater flexibility during a surgical procedure. The bone anchor assemblies disclosed herein include an implantable shank and a receiver member having two spaced apart arms which form a U-shaped seat to receive a rod, among other components. The bone anchor assemblies disclosed herein also provide a number of features to enhance capability and usability. Examples include features to facilitate better implantation of the shank, better coupling of instrumentation to the anchor, better performance in reducing a spinal fixation element, such as a rod, into the receiver member seat, and others.Type: ApplicationFiled: March 2, 2022Publication date: September 8, 2022Inventors: Christopher Mickiewicz, Ellen Roberts, Alec Manson

Publication number: 20220202453Abstract: Systems and methods for reducing the risk of PJK, PJF, and other conditions are disclosed herein. In some embodiments, a longitudinal extension can be added to a primary fixation construct to extend the construct to one or more additional vertebral levels. The extension can be attached to a first attachment point, such as a bone anchor implanted in a vertebra that is superior to the primary construct. The extension can also be attached to a second attachment point, such as a component of the primary construct or an anatomical structure disposed inferior to the first attachment point. The extension can be more flexible than the primary construct and/or can limit motion to a lesser degree than the primary construct, thereby providing a more-gradual transition from the instrumented vertebrae to the natural patient anatomy adjacent thereto. The extension can be placed with little or no soft tissue disruption.Type: ApplicationFiled: December 1, 2021Publication date: June 30, 2022Inventors: Christopher Mickiewicz, Michael O'Neil, Randal Betz, Baron Lonner
