摘要：
A spinal distracter and stabilizer has resilient, conformable bone contacting sections which are separated by an expandable chamber that extends from one of the sections, and which forms a ratchet with the section, ensuring that once expanded by being filled with a substance, cannot contract absent intervention by a medical practitioner. The stabilizer may be filled with a material which solidifies, after which some or all of the device may biodegrade. The device may also be provided in separable portions to facilitate implantation. The conformable sections distribute the distraction and stabilizing force evenly over the bone surface, reducing the incidence of disruption to the integrity of the bone.
