Clinical Observation And Analysis Of SPR Operation In Posterior Rhizotomy Proportion

Objective:to study the selective spinal nerve root after a small bundle of partial amputation (selective posterior rhizotomy, SPR) intraoperative after each small beam to cut off the proportion of the design, the related influencing factors, the surgical curative effect and complications. Methods:2012November to2013May119cases of children with SPR operation, were collected preoperative, postoperative limb muscle tension levels, intraoperative electrical muscle stimulation threshold, the posterior root small dominating segment contraction muscle group size, postoperative relief all relevant data rate and operation in the corresponding section cutting ratio of root small bundles were compared between sexes, with the two sample test. Results:Good correlation between these factors and intraoperative spinal nerve followed by a small cut ratio, correlation coefficient rare respectively5.6132,2.0466,2.3657, and6.8103, P<0.05, with statistical significance, gender differences in children with spinal nerve root after cutting a wispy showed no statistical significance. Preoperative limb muscle tension is high, intraoperative electrical stimulation threshold is small, dominated by segmental muscle group shrinkage reacted strongly, cut the ratio should be appropriate to increase muscle tension, reduce excessive, relieve spasm symptoms, this study with preoperative limb muscle tension was significantly reduced, spasticity, improvement limb motor function than before, with a certain degree of improvement or recovery, basically reached the expected effect of preoperative, postoperative minority children with short limb numbness, sensory disturbance, very few children with surgical incision swelling and fat liquefaction, not long time retention of urine, urinary incontinence, and bowel disorders and other complications. Conclusion:through the research, the author thinks that the muscle tension levels, electrical stimulation threshold, intraoperative muscle strength and spasticity lift is directly related to small beam to cut off the range of small beam for determine the proportion of cut should be comprehensive, integrated consideration with the specific circumstances, to avoid cutting off excessive cause new dysfunction or deformity. disturbance, weakness, can not be fixed lower limb posture, increase lower limb dysfunction, and even generate new defects.
