ABSTRACT
[Objective] To evaluate the 5 year follow-up result of posterior lumbar interbody fusion(PLIF)using autogenous bone and double cage.[Methods]Totally 84 cases received PLIF surgery.Hospitalized records and X-ray findings at 1,3,5 years post-operation were collected and Oswestry disability index(ODI)was evaluated to observe the fusion effect and adjacent segment degeneration(ASD).[Results]The difference was significant between preoperative ODI and 1 year postoperative ODI(P
ABSTRACT
Objective To explore the value of MRI features of the appendixes bone in differentiating vertebral myeloma from metastatic tumor. Methods There were vertebral myelomas and metastatic tumors in 32 cases respectively involved the appendixes bones,the number,positions,forms,size,distribution ranger and T_1 of the lesions,the vertebral pedicles and the diameters of the cross sections of vertebrallaminas were analysed.Results Among the 32 cases of vertebral myeloma,the destruction of appendixe was bilateral in 21 cases andunilateral in 11 cases.Totally 89 lesions were checked out ,of them,the lesions were the form of mass or nodule in 39,patch in 28,mixed form in 12.In compared with its adjacent and normal one,the ratio of evary invaded vertebral pedide , vertebral lamina and spinous process was between 1.048~2.135 . There was significant difference (P0.05).Conclusion The difference of MRI features of the appendixes bone invaded by vertebral myeloma and by metastatic tumor is helpful in distinguishing vertebral myeloma from metastatic tumor.
