Relationship between Lumbar MRI Multi-Parameters,VAS Score and JOA Score and the Efficacy of Percutaneous Endoscopic Lumbar Discectomy in Patients with Lumbar Disc Herniation
Objective:To investigate the relationship between lumbar magnetic resonance imaging(MRI)multi-parameters,visual analogue scale(VAS)score and Japanese Orthopaedic Association(JOA)score and the efficacy of percutaneous endoscopic lumbar dis-cectomy(PELD)in patients with lumbar disc herniation(LDH).Methods:144 patients with LDH underwent PELD,and lumbar MRI was performed before and 1 year after operation.VAS and JOA scores were used to evaluate the degree of lumbar pain and lumbar function.According to the results of PELD,the patients were divided into excellent efficacy group and poor efficacy group.The differences of lumbar MRI multi-parameters,VAS score and JOA score between different groups before and 1 year after operation were compared.Results:After treatment,the improvement of nerve root compression and displacement in the excellent efficacy group was significantly better than that in the poor efficacy group(P＜0.05).Compared with the poor efficacy group,the epidural indentation diameter,lumbar curve index and intervertebral disc angle of the excellent efficacy group increased at 1 year after operation,while the intervertebral space height decreased(P＜0.05).Compared with the poor efficacy group,the VAS score of the excellent efficacy group was significantly lower,and the JOA score was significantly higher(P＜0.05).Conclusion:Lumbar MRI multi-parameters,VAS score and JOA score are closely related to the postoperative efficacy of PELD in LDH patients,which can be used as an important basis for evaluating the postoperative efficacy of PELD in LDH patients.
