Objective To evaluate the effect of transverse position and numbers on the stability of the spinal pedicle screw fixation during the pedicle cortex perforation. Methods The vertebral compression fracture was performed in the L1 vertebral body using the Chiba's method from 60 fresh thoracic and lumbar vertebrae samples of sheep(T13-L3),which were randomly divided into 6 groups(A,B,C,D,E,and F)using a lottery method. Bilateral pedicles of vertebral arch of T14 and L2 were inserted pedicle screws,connecting titanium rods to fix T14-L2 segments. Then the samples of groups B,C,D,E,and F were removed a quarter of right side of lateral T14 thoracic pedicle cortical,which were considered the pedicle cortex perforation model. Finally,each group was fixed on different numbers of crosslinks:group A(0 crosslink,Intact),group B(0 crosslink,NCL),group C(1 crosslink,1/2 of the rods,MCL),group D(1 crosslink,1/3 of the rods close to T14,PCL),group E(1 crosslink,2/3 of the rods away from T14,DCL)and group F(2 crosslinks,1/3 and 2/3 of the rods respectively,TCL). After all samples were subject to 10 000 times of fatigue test with biomechanics test machines,the axial compressive stiffness,range of the motion(ROM)of the 6 directions(flexion,extension,lateral bending,and axial rotation),and the maximum pullout of the screws of the T14 pedicle cortex perforation were measured and compared among these 6 groups. Results The axial compressive stiffness in groups A,C,D,E,and F was significantly higher than that in group B(all P<0.05),and group A was significantly higher than group F(P<0.05) . The maximum pullout in groups A,C,D,E,and F were significantly higher than that in group B(all P<0.05),and group A was significantly higher than group F and groups C,D,and E were significantly lower than group F(all P<0.05). ROM of flexion,extension,lateral bending,and axial rotation in groups A,B,C,D,E,and F were significantly lower than that in group B(P=0.000),and ROM of left and right axial rotation in groups C,D,and E were significantly higher than in that group F(P=0.000). Conclusions During the pedicle cortex perforation,adding of one crosslink can improve the stability of the pedicle cortex perforation,and adding of two crosslinks can approximately achieve the same stability as the pedicle screw fixation with no pedicle cortex perforation. The location of the crosslink has no obvious effect on the short segment of spinal fixation.

Objective To evaluate the clinical application and therapeutic effect of interventional embolization in treating renal pseudoaneurysms. Methods The clinical data of 11 patients with renal pseudoaneurysm, who had received interventional embolization management at authors’ hospital, were retrospectively analyzed. The embolic agents used in the embolization procedure included conventional steel coil, gelatin sponge particles, PVA, etc. All the patients were followed up for 6-24 months. Results Single renal pseudoaneurysm was found in all the 11 patients. Clinically, symptom of bleeding was seen in 3 cases. The renal pseudoaneurysm was located at the upper (n=1), middle (n=4) and lower (n=5) renal artery of the kidney, and in one case the renal pseudoaneurysm was situated at the accessory renal artery. In performing renal artery embolization, pure PVA was used in one case, spring steel coil in one case, PVA together with spring steel coil in one case, and gelatin sponge combined with spring coil in 8 cases. After the embolization, the pseudoaneurysm was no more visualized, the contrast extravasation disappeared, and the parent artery was manifested as a residual root. During the operation the patients had no obvious discomfort. Within one week after embolization therapy, 2 patients developed hemorrhage, and their hemoglobin, white blood cell count and hematocrit were significantly increased. During the follow-up period, all patients showed no recurrence signs, and routine urine tests were normal. Conclusion For the treatment of renal pseudoaneurysms, interventional embolization is minimally-invasive, safe and reliable; this technique can maximally protect the normal kidney tissue, quickly control the bleeding and effectively save the life of patient. Therefore, it is worth promoting this treatment in clinical practice.
