Interspinous vertebral stabilization devices

摘要

The present invention provides interspinous vertebral and lumbosacral stabilization devices, and methods of using these devices for treating spinal instability conditions. The invention includes interspinous vertebral stabilization devices adapted for placement between the spinous processes of two or more adjacent vertebrae. The invention also includes lumbar stabilization devices adapted to be placed between a lumbar vertebra and an adjacent vertebra, including the first sacral vertebra (S1), to stabilize the lumbosacral region of a patient, and method for using such devices.

主权项

1. An implantable interspinous stabilization device, comprising:
a flexible body including:
a first portion having a bone-contacting region configured for placement beneath a spinous process of a vertebra and a laminar hook connected thereto, the laminar hook having a protrusion for extending around a lamina of the vertebra;a second, base portion having an attachment end for cooperating with a bone attachment member; anda flexible element connecting the first and second portions; the device further comprising a bone attachment member attachable to the second, base portion and configured to secure the device to a bony surface of an adjacent vertebra.
