ABSTRACT
Objective To observe the positional relationship of lumbar nerve roots and its main adjacent structures with CT data, and to conduct 3D construction and measurement,so as to provide anatomical basis for percutaneous lumbar diskectomy(PLD).Methods CT serial tomography dataset of 30 healthy adults' lumbosacral portions were imported into Mimics 17.0 software to segment related structures and obtain the layers of different structures.The structures were 3D reconstructed and virtually demonstrated.The lumbar nerve roots and their main surrounding structures were observed and measured.Results The minimum distances between the lumbar nerve roots and the superior articular processes increased gradually from L3 to L4 intervertebral disc layer to L5 to S1 intervertebral disc layer.The 3D model clearly displayed the morphology and spatial relationship of the lumbar nerve roots and their adjacent structures in lumbosacral portion.The lower the lumbar intervertebral discs were,the thicker they were.The distances from the middle point of the back of lumbar intervertebral disc to the end of the superior spinous process of lumbar vertebra increased at first and decreased then,and the distance in L3 to L4 intervertebral disc layer was the farthest.Conclusion The relationship between lumbar nerve roots and superior articular processes,the intervertebral disc thickness variance and the change of the distances from lumbar intervertebral disc to the end of the superior spinous process have been analyzed in this study,and the clinic basis has been laid for percutaneous lumbar diskectomy.
ABSTRACT
Objective To evaluate the effect of fast track surgery nursing on percutaneous lumbar diskectomy. Methods A total of 126 patients were randomly divided into the control group and the experimental group,the control group received traditional nursing plan, the experimental group was given fast track surgery nursing plan. The nursing effect was observed. Results Postoperative anal exhaust time, feeding time, walking time, length of hospital stay ofthe experimental group were (1.61±0.71) days, (2.01±0.71) days, (4.70±2.12) days, (12.72±2.07) days, whichwere significantly shorter than those of the control group, which were (3.37±0.93) days, (2.27±0.63) days, (8.40±3.21) days, (15.81±2.14) days, the difference between two groups were statistically significant (t=4.012-6.068, P0.05). The Rdand Morris Questionnaire score of the experimental group was 21.67±3.48, which was higher than that of the control group(14.43 ± 2.01), the difference between two groups was statistically significant(χ2=6.077, P <0.05). Conclusion Fast track surgery nursing can promote the patient's postoperative rehabilitation ,reduce the postoperative complications, shorten the length of hospital stay and improve the quality of life.
ABSTRACT
Objective To evaluate the curative effect and optimal indications of reformed percutaneous lumbar diskectomy (RPLD) for the treatment of lumbar disc herniation.Methods One handred and thirty-three patients with lumbar disc herniation were treated by RPLD, of them, 20 cases were lumbar disc extrusion and 113 cases were lumbar disc protrusion. After the procedure, 85 patients underwent flush of intervertebral space with antibiotic saline and 48 patients underwent 10 ml(40?g/ml) medical ozone-injection inside the disc to prevent infection. All patients were followed up over the course of 3 months. The therapeutic effect was evaluated according to the MacNab criteria. Results All 133 cases underwent RPLD were successful. The total efficacy was 81.9%, There were no serious complications after operations. Conclusion RPLD is an effective method in the treatment of lumbar disc herniation. Both intradiscal ozone-injection or intradiscal antibiotic saline flush after RPLD can reduce the opportunity of infection.
ABSTRACT
0.01). No serious complications occurred. Conclusion Both PLD+IDET and PLD are very effective in treating lumbar disc herniation. IDET is very helpful in relieving low back pain, although it can hardly improve patient's daily activities.
ABSTRACT
Objective To evaluate the value of PLD associated with O 3 injection for the treatment of lumbar disc heniation.Methods Lateral decubitus position on healthy side under the direction of DSA, a working pipe was inserted from the back lateral way to damage the disc contents through multiple angles followed by extirpation of the nucleus pulposus and then injecting O 2-O 3 10 ml into the lumbar disc space and near by area of the inter vertebral foramina. As for patients with L4-5 and L5-S1 protrusions the main lumbar discs can be treated in the same way, but for another minor one, the injection of O 2-O 3 10 ml into the lumbar disc and the nearby intervertebral foramina and ethanol through a 21G needle would be properly promising. Results Puncture and technical opertaion were performed successfully in all the patients with excellent results in 63, good in 27, and poor in 10. 120 cases with injection of O 2-O 3 into the lumbar discs showed the figure of lumbar space displaying clear in 37 cases, less clear in 35 cases, only gas entering lumbar disc at the needling point with lumbar space displaying unclear in 30 cases and lots of gas entering the front space of canalis vertebralis cavitas epiduralis in 18 cases. Conclusions PLD associated with O 3 injection is the advantageous supplement mutually posscessing safety and efficancy.
