Analysis On Clinical Curative Effects Of Percutan Eous Kyphoplasty Under3D Navigator On Treating Osteoporotic Compression Fractures

Objective:To observe clinical curative effects of percutaneous kyphoplasty (PKP) under3D navigator on treating osteoporotic compression fractures.Methods:A total of70patients (96vertebral bodies) were enrolled in this study, all of whom have under gone PKP in Yanbian University Affiliated Hospital from September2009to October2013. Among them,37cases (54vertebral bodies, Group A) had PKP guided by3D navigator while33cases (42vertebral bodies, Group B) had PKP under C arm X-ray perspective. In group A,15cases (18vertebral bodies) were male and22cases (36vertebral bodies) were female, with the average age of72.1years old; while in group B,13cases (16vertebral bodies) were male and20cases (26vertebral bodies) were female, with the average age of71.2years old. Bone cement injection was about3～4ml. Group A and Group B were observed for puncture approach, successful rate of pedicle puncture, filling rate of bone cement, operation duration, number of perspective, RDQ and VAS scores before and after surgery, leakage of bone cement determined during operation, and distribution of bone cement by postoperative X ray film review.Result:70cases of patients successfully completed surgery. Success rate of one-time puncture in Group A was100%and the bone cement was successfully filled. Leakage of bone cement was found in2cases. In one case the bone cement was leaked into the superior endplate and in the other one it was leaked into the anterior vertebral body. Success rate of one-time puncture in Group B was87.3%and the leakage of bone cement was found in3cases. The bone cement was leaked into the paravertebral disc soft tissue. There was no statistical difference of the leakage rates between the two groups (P>0.05). Average surgery duration was29.8±5.8min in Group A and33.2±8.4min in Group B, and the difference between the two groups were not significant (P>0.05). The number of perspective was significantly less in Group A than that of the Group, and there was obvious difference between the two groups (P<0.01). There were significant differences of RDQ and VAS scores before and after surgery (P<0.05), but the difference between the groups was not obvious (P>0.05).Conclusion:PKP guided by3D navigator has the advantages of safer and higher accuracy than the traditional PKP guided by CRM. PKP guided by3D navigator can establish more precise approach than PKP guided by CRM, reduce the complications and improve the clinical curative effect. PKP guided by3D navigator has higher success rate and accuracy of vertebral puncture than PKP guided by CRM.
