Abstract:
Objective To investigate the feasibility of percutaneous transforaminal endoscopic spine system in thoracic discectomy for disc herniation. Methods One patient with thoracic disc herniation involved the level of vertebral segment in T11/12 was treated with percutaneous transforaminal endoscopic spine system and followed up for 1 month. The targeted puncture was performed under local anesthesia and fluoroscopic guidance with patient in prone position. The foramen of T 11/12 was enlarged gradually with four trephinations, and the working cannula was inserted transforaminal into the canal. Then the herniation was exposed and removed with full endoscopic technique, including the loosen nucleus pulposus. The dural sac was exposed and released adequately. Drainage was placed during operation. Results The procedure was successfully carried out and the dural sac was completely released. The drainage was removed in the second day of operation. The patient could walk in the third day after operation with obvious relief of back and leg pain. At the follow-up of one month postoperation, the visual analogue scale of leg pain decreased from 8 to 1, and the Oswestry disability index (ODI) decreased from 64 to 4. According to MacNab scale, excellent result was acquired. Conclusion There is the feasibility of the percutaneous transforaminal endoscopic spine system in thoracic discectomy for disc herniation. It is a good minimal invasive technique with good results and high technical requirements for surgeons.
