Abstract:
Objective To study the clinical effect of the BacFuse for the lumbar disc herniation(LDH) and to discuss the affect for symptom of patients and structure of spine.Methods Collected the patients suffered from LDH retrospectively who had been implanted the BacFuse.There were 25 patients (29 surgical levels) included in the study.The clinical and X-ray assessment have been done on preoperation,postoperation,3 month,6 month and 12 month.Clinical index used visual analogue scale (VAS) score,oswestry disability index (ODI) score and Japanese Orthopaedic Association (JOA) score assessed clinical symptom and physical function.The intervertebral angle,posterior disk height and foraminal height were measured in X-ray.The patients were taken CT at preoperation and postoperation.The area and distance of herniated disc were measured in CT scan.Results In the aspect of clinical effect,25 cases were finished operation successly.The VAS score decreased from (6.61±1.29) points on preoperation to (2.78±1.00) points on the last follow-up,the ODI score decreased from (31.9±8.3) points to (15.9±6.4) points,the JOA score increased from (9.6± 3.0) points to (18.8± 3.2) points.In the aspect of spine structure,the intervertebral angle decreased from 10.1°±5.4° on preoperation to 8.4°±4.9° on the last follow-up,the posterior disk height increased from (0.65±0.29) cm on preoperation to (0.78±0.27) cm on the last follow-up and the foraminal height increased from (2.01±0.35) cm on preoperation to (2.16±0.37)cm.There was significant difference on posterior disk height and foraminal height between preoperation and postoperation,while the posterior disk height lost (0.07±0.12) cm (9.3％) and foraminal height lost (0.06±0.19) cm (2.7％).The CT showed that area of herniated disc decreased from (4.10±0.78) mm to (3.72±0.66) mm (9.3％) and distance of herniated disc decreased from (96.4±37.8) mm2 to (83.8±31.1) mm2 (7.4％).Conclusion BacFuse can relieve symptom and affect the biomechanics of the spine,makes the herniated disc retract partially,playing a Internal Retractor role in spine,and it is a new effective therapy for LDH.
