摘要：
A spinal implant structure includes a hollow cylinder and a biodegradable polymer membrane. The hollow cylinder is implanted in a bone damaged part of human vertebra. The biodegradable polymer membrane is formed to a part of a surface of the hollow cylinder. Thus, the biodegradable polymer membrane blocks invasion of soft tissues, and then the bone fillers integrated with vertebra are maintained without loss.
