ABSTRACT
Objective To analyze the clinical value of transforaminal endoscopic minimally invasive surgery for the treatment of recurrent lumbar disc herniation.Methods Strictly included in the criteria,47 patients diagnosed with recurrent lumbar disc herniation who was treated unsuccessfully with conservative treatment were selected from our department from May 2011 to December 2015.There were 31 males and 16 females,with an average age of 43.45 ±3.37 years old (29-62 years old).There were L3,4 section in 4 cases,L4,5 section in 32 cases,and L5S1 section in 11 cases.The interval between the first operation and the reoperation was between 10 and 185 months,with an average of 49 months.In the first operation,there were 11 cases of posterior intervertebral disc endoscopy (MED) surgery,and 36 cases of decompression of vertebral disc nucleus pulposus surgery.Take a prone position under local anesthesia percutaneous puncture intervertebral foramen in the endoscopic minimally invasive surgery,intraoperative decompression of vertebral canal and nerve root canal,removal of intervertebral disc nucleus pulposus tissue,explore and release nerve root.The Oswestry disability index (ODI),visual analogue scale (VAS) and improved Macnab standard were used to assess the efficacy of the operation.Operation segments intervertebral height change,lumbar power X-ray slice of intervertebral Angle was measured according to preoperative and last follow-up of lumbar lateral X-ray observation,and lumbar spine motion (the range of motion,ROM) was calculated.Results All cases were successfully performed,no open surgery,and all cases were followed up.The average surgical blood volume was 10.3± 2.7 ml,the operation time was 63.5±11.6 min,no nerve root injury,dural injury,cerebrospinal fluid leakage,muscle strength decline,secondary obstruction,lumbar instability or other serious complications occurred.The follow-up time was from 18 to 52 months,with an average of 35.5±5.1 months.The preoperative ODI 51.35± 15.29 decreased to 3.31 ±2.17 at the last postoperative follow-up,the preoperative VAS score 8.11 ± 1.05 decreased to (1.03± 0.81) at the last postoperative follow-up,and the difference was statistically significant (P < 0.05).As to the last follow-up evaluation of curative effect,according to the modified MacNab method,the fine rate was 87.2%;At the time of the last follow-up,surgery intervertebral disc height of front and rear section before and after surgery had no significant differences (P > 0.05),the motion of operation segmental lumbar (the range of motion,ROM) had no significant difference (P > 0.05).Conclusion Under the premise of strict control of surgical indications,the clinical efficacy of minimally invasive surgery for the treatment of recurrent lumbar disc herniation is reliable.The transforaminal approach does not affect the stability of the spine.The operation has the advantages of small trauma,fewer complications,and is safe and effective.
