摘要： In one embodiment, an expander set includes a first and second expander. The first expander includes an outer surface having a first engagement feature and a groove and the second expander includes an inside surface having a second engagement feature adapted to engage with the first engagement feature. The inside surface of the second expander is shaped to correspond to a portion of the outer surface of the first expander. Additionally, the groove on the outer surface of the first expander is sized and shaped to accommodate a rod of a retraction system such that when the first expander is advanced within the retraction system, the rod remains within the groove. When the first and second expanders are engaged with one another, they define an oblong cross-section.

摘要： A surgical instrument includes a cannulated body extending along an axis and having a first working end spaced along the axis from a second working end. The surgical instrument may be used with a fenestrated screw assembly, a delivery unit, and an alignment guide wire. The first working end of the surgical instrument is configured to transmit a force to a delivery unit in a direction about the axis and the second working end is configured to transmit a force to a delivery unit in a direction generally transverse to the axis. The first working end may be used to rotate the delivery unit to thereby removably attach the delivery unit to the fenestrated screw assembly. The surgical instrument may be repositioned to engage the second working end with the proximal end of the delivery unit to maintain the rotational position of the delivery unit.

摘要： A virtual surgical cutting guide may have first and second slots defining first and second axes respectively. The virtual surgical cutting guide may be positioned away from a vertebral body such that the first and second axes intersect at a distal point located in an interior of the vertebral body. The virtual surgical cutting guide may include the virtual surgical cutting guide with first and second cutting instruments. A method of performing a pedicle subtraction osteotomy may include the steps of placing the virtual surgical cutting guide over the first and second cutting instruments.

摘要： Disclosed herein are a spinal fixation assembly and method to provide adequate rigidity and support for a vertebral column without requiring additional pedicle screws and spinal rods. The spinal fixation assembly includes a spinal rod loop with multiple sides configured to be attached to a vertebral body with two or more pedicle screws. Each pedicle screw is adapted to fit at various locations along the spinal rod loop.

摘要： In one embodiment, the present disclosure relates to a retractor apparatus that includes a retractor frame, five arms attached to the retractor frame and five rods each attached to one of the five arms. Each rod includes a convex surface facing a center of the retractor frame. At least two of the five rods are movable independently from one another. A first rod of the five rods includes a longitudinal axis and is translatable along the longitudinal axis. Further, the first rod is attached to a first arm of the five arms and is pivotable relative to the first arm. The axis of pivot is offset from the longitudinal axis through which the first rod translates.

摘要： In one embodiment, a surgical rigid arm (100, 150, 200, 900) includes a first portion (102, 152, 202, 902), a second portion (103, 153, 203, 903) and a central portion (105, 154, 205, 906), where the central portion is extends between the first and second portions. A first end of the first portion and a second end of the second portion are each attached to a peripheral side (14) of a surgical bed (10, 30) such that the first portion and the second portion extend from the surgical bed in a first direction. The central portion extends substantially horizontally and is positioned over the surgical bed, the central portion being connected to the surgical instrument such that a load from the surgical instrument is distributed across the central portion to the first portion and second portion to provide rigid support for the surgical instrument.

摘要： In one embodiment, a system includes a retractor with a plurality of rods that are cylindrical over part of their length, a light source, and a fiber optic cable, where at least one rod includes a body with an opening therein. The opening extends from an upper surface of the rod, through an interior of the rod, and then to a side surface of the rod located between ends of the rod. The opening is sized so that at least a single monofilament fiber optic cable is disposable therethrough. The system is adapted so that any number of rods may include a fiber optic cable disposed therein and so that the cable may be easily removed or inserted from the rod during use of the retractor.
