ABSTRACT

Objective To observe the clinical effect of transforaminal endoscopic surgical system (TESSYS) technique for atypical lumbar disc herniation. Methods Eighteen patients with atypical lumbar disc herniation underwent TESSYS technique under local anesthesia. Numerical rating scale (NRS) was used to evaluate the sciatica and/or back pain. The outcomes were evaluated by Oswestry disability index (ODI) and the Macnab score. Results The postoperative NRS scales were significantly lower than preoperative one (P<0.01). The postoperative ODI was lower than preoperative one (P < 0.05). Good rate of modified Macnab criteria was 88.89%. One patient occurred right hip pain and disappeared after partial closure. one patient turned to open surgery at 1 week. Conclusion The TESSYS technique was an effective method for atypical lumbar disc herniation. It has satisfactory clinical effect which is worthy of spreading for clinical application.
