Spinal implant for use during retroperitoneal lateral insertion procedures

Номер: US20120010717A1

Автор: Scott Spann

Принадлежит: Individual

A method is disclosed for introducing a spinal disc implant into an intervertebral space of a subject. The subject is placed in a lateral position, and the anterior face of the spinal disc intervertebral space is accessed, between the L5 and S1 vertebrae, from an anterior and lateral retroperitoneal approach. An operative corridor to the anterior face of the spinal disc space is established by introducing a retractor instrument anterolaterally to the spinal disc space between the anterior superior iliac spine and the anterior inferior iliac spine. The damaged spinal disc contents are removed from the intervertebral space through the operative corridor, and the implant is advanced into the intervertebral space at an oblique angle and pivoted to position the implant substantially laterally within the intervertebral space. Elongated retractor and insertion instruments, as well as a modified disc implant, are also disclosed for carrying out the method.

Implants for repairing tissue defects, such as cartilage tissue defects, and methods of their preparation and use are disclosed. A mold of a tissue defect is prepared by pressing upon the defect a substrate having shape memory, such as aluminum foil. The mold, which has contours substantially conforming to those of the defect, is removed from the defect, and tissue particles are added to the mold ex vivo. A biological carrier such as biocompatible glue is also added to the mold. The combination of tissue particles and the biological carrier thereby form an implant, which retains its shape after separation from the mold. The implant can be transferred to the tissue defect, with contours of the mold matching corresponding contours of the defect.

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.

Method of using instruments and interbody spinal implants to enhance distraction

Номер: US20120239151A1

Автор: Chad J. Patterson, Peter F. Ulrich, JR.

Принадлежит: Titan Spine Inc

A method of using an interbody spinal implant by implanting the spinal implant into a patient in need of the spinal implant. The method includes accessing the disc space of the patient and locating the center of the disc space. The disc space is incised by making a window in the annulus of the disc space for insertion of the spinal implant. The endplates are cleaned of all cartilage and the disc structure, which is encapsulated by the annulus, is removed while avoiding damage to the endplate structure of the vertebrae. Optionally a size-specific rasp is selected and the disc space is cleared of all soft tissue and cartilage. Optionally the disc space is distracted by sequentially expanding it with distractors of progressively increasing heights. A spinal implant having a pre-determined size sufficient to balance frictional fit and elongation of the annulus is selected and seated in the disc space.

Selectively Expanding Spine Cage With Enhanced Bone Graft Infusion

Номер: US20130190875A1

Автор: Damien J. Shulock, John E. Ashley, Rudy Pretti, Thomas Grotz

Принадлежит: Coalign Innovations Inc

A selectively expanding spine cage has a minimized cross section 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 the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. 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.
