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.
摘要:
The present application is directed to a device for connecting an elongated member within a patient. The device includes a body with a receiving section to receive the elongated member, and an engagement section to engage a support structure, such as a vertebral member. The receiving section is sized to receive the elongated member in a first orientation. The process of securing the elongated member within the receiving section causes the device to pivot about the elongated member to a second orientation. This pivoting motion causes the engagement section to more securely attach to the support structure.

摘要:
A system is provided for use in orthopedic surgery, for example to connect a spinal rod with a vertebral screw or hook. The system generally includes a receiver member for receiving an elongated member, a bone implant member, such as a bone screw, and a locking washer to assist in locking the receiver member at a desired angular position relative to the bone implant member. The receiver member and the washer may be positioned on opposite sides of the bone implant member. Additionally, the receiver member may define an aperture to receive a closure member to lock an elongated member in a passage in the receiver member.
摘要:
A vertebral connecting rod and a spinal osteosynthesis device are disclosed. The vertebral connecting rod 1, which is adapted to be rigidly supported with a pair of spinal implants 5, 5 anchored to vertebral bodies 3, 3 such as thoracic vertebrae or lumbar vertebrae etc., has a pin-shaped section 7 of which one distal end formed with a hook segment 11 for hanging an interconnecting member 9. A slip-out protective member 19 is engageable with the hook segment 11. In a preferred embodiment, the pin-shaped section has at its arbitrary position formed with an engagement convex segment 27 adapted to engage with a corresponding engagement concave recess formed in the spinal implant 5.
