摘要:
A positioning frame for supporting a patient to facilitate different surgical approaches to the spine includes a main support beam, first and second support structures, a torso-lift support, and a pelvic-tilt support. The main support beam has a first end, a second end, and a length extending between the first and second ends. The main support beam defines an axis of rotation relative to at least a first support structure and a second support structure, and the axis of rotation substantially corresponds to a cranial-caudal axis of the patient when the patient is supported on the positioning frame. The first and second support structures support the main support beam, and space the main support beam from the ground. The torso-lift support is attached to the main support beam, and is configured to pivot a chest support plate between at least a first position and a second position to move the torso of the patient between an unlifted position and a lifted position. The pelvic-tilt support is attached to the main support beam, and is configured to support the thighs and the lower legs of the patient. Portions of the pelvic-tilt support are pivotal with respect to one another to facilitate adjustment of the hips of the patient.

An adjustable surgical frame for supporting a patient to facilitate different surgical approaches to the spine of the patient includes a first end, an opposite second end, and a length extending between the first and second ends thereof. The surgical frame has a longitudinal axis extending between the first and second ends along the length thereof, and includes a first support surface, a second support surface, and a third support surface. The surgical frame also includes an adjustable chest support, an adjustable hip and upper leg support, and an adjustable feet and lower leg support. The surgical frame is moveable between a first position, a second position, and a third position, and the chest support, the hip and upper leg support, and the feet and lower leg support are moveable to accommodate differently sized patients on the surgical frame.

A surgical instrument comprises a first member defining a longitudinal axis. A second member is connected with a pivot. A third member defines a first axis disposed at an angular orientation relative to the longitudinal axis and is connected with the pivot. The second member is translatable relative to the first member to rotate the pivot to move the third member between a first orientation and a second orientation to space vertebral tissue. Systems and methods are disclosed.

An expandable spinal implant for insertion in a disc space between two adjacent vertebrae. The expandable spinal implant is moveable from an unexpanded configuration to an expanded configuration. The expandable spinal implant includes a first plate having plastically deformable links, a second plate, two transverse members, and a screw. The screw forces apart the transverse members which causes rotational deformation of the links and separation of the plates.

Methods and devices for performing percutaneous surgery in a patient are provided. A retractor includes a working channel formed by a first portion coupled to a second portion. The first and second portions are movable relative to one another from an unexpanded configuration to an expanded configuration to increase the size of the working channel along the length of the working channel while minimizing trauma to skin and tissue.

摘要:
A spinal correction apparatus comprises a body. A ratchet is disposed with the body. A longitudinal element is connected to the ratchet. A force is applied to at least a portion of the apparatus that causes dynamic incremental movement of the longitudinal element relative to the body in at least one direction. Methods of use are disclosed.
