Selectively Expanding Spine Cage, Hydraulically Controllable In Three Dimensions for Vertebral Body Replacement

Номер: US20120116518A1
Автор: Rudy Pretti, Thomas Grotz
Принадлежит: Coalign Innovations Inc

A selectively expanding spine cage has a minimized diameter in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of vertebrae to effectively distract the anterior disc space, stabilize the motion segments, eliminate pathologic spine motion, or effect vertebral body replacement. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

Systems and methods for planning surgical procedures involving custom medical implants that can involve the selection, design and/or creation of custom medical implants and/or the selection, modification, and/or design of custom surgical procedures related to those implants. Certain embodiments allow implants to be selected, designed, created, or otherwise customized and then placed in patients using non-standard surgical techniques. The invention provides greater flexibility in implant use by allowing a surgeon to revise, create, or otherwise select surgical techniques for custom implants and, ultimately, provide better treatment in a greater variety of medical circumstances. Certain embodiments of the invention involve computer assisted surgery to provide for implant-related surgery involving non-standard surgical steps and/or implants.

A device for performing a surgical procedure on a knee includes an adjustable femoral portion, a tibial portion and at least one sensor coupled with the femoral and/or tibial portions to sense pressure exerted by the femoral and tibial portions against one another. The femoral portion is adapted for removably coupling with a distal end of a femur to adjust tension in soft tissue adjacent the knee and has at least one positioning feature adapted to move relative to the distal end of the femur as the femoral portion is adjusted, thus helping position a femoral prosthetic on the distal end of the femur. The sensor(s) may be adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may be displayed as data on a visual display. Adjustments to the femoral member may be made to balance pressure at flexion and extension of the knee.

Regarding semi-constrained artificial ball (head) and socket (cup) joints such as the hip or shoulder joint, which allow for certain numbers of degrees of rotation along three independent axes. For example, one embodiment creates at least two axes of rotation through a super-spherical space carved out of the inner surface of the cup, with a cup-cable connecting two points along the super-spherical space, and a perpendicular head-cable looping around the head and the cup-cable within the super-spherical space, and with the head-cable residing in a groove. Another embodiment creates two axes of rotation through a combination of a 1) swivel with lever and/or 2) cable attached to a circular track (with the knob or ring around cable facing inward or outward), both of which have the center of the head as the center of rotation. The third axis may be created by a horizontal swivel and by wiggle room.
