ObjectiveTo investigate safety and efficacy of one-stage pedicle screw fixation plus 360° spinal canal decompression and reconstruction in treatment of severe thoracolumbar burst fractures.MethodsThe study reviewed 11 patients (8 males and 3 females, at age range of 19-59 years, mean 34.4 years) with severe thoracolumbar burst fracture, who underwent one-stage posterior pedicle screw fixation, 360° spinal canal decompression and reconstruction. The injury location was at T12 in one patient, at L1 in three, at L2 in two, at L3 in three and at L4 in two. According to AO classification, all patients were with type A 3.3 fractures. McCormack load score was 7-9 points ( average 8.2 points). Based on the Frankel' s scale, the spinal cord function was classified as grade A in one patient, grade B in one,grade C in five and grade D in four. ResultsAll the operations accomplished successfully, with operation duration for 3.5-4.5 hours ( mean 4.1 hours) , blood loss for 900-2 800 ml ( mean 1 750 ml) and allogeneic blood transfusion for 400-1 200 ml ( average 760 ml). There was no complication either during or after operation. The loss rate of the anterior vertebrae column height was 48％ -85％ ( average 64.2％ )before operation and recovered to 95％ -100％ (average 98.6％ ) of the normal. The kyphotic Cobb angle was at -12°-35 ° ( average 12.1 ° ) before operation and recovered to - 30°-7 ° ( average - 8.1 ° ) after operation. The spinal canal stenosis rate was improved remarkably. The patients were followed up for 10-18 months (average 14. 5 months), which showed solid bone fusion, with no implant failure. The spinal cord function was improved Ⅰ to Ⅲ degrees in all patients except for one patient at grade A. One patient had mild lower back pain.ConclusionsOne-stage pedicle screw fixation plus 360° spinal canal decompression and reconstruction is a good alternative for severe thoracolumbar burst fracture, but it is essential for choosing strictly the surgical indications.

BACKGROUND:To decrease operation amount of finite element analysis and increase its clinical practice,previous studies explored the material properties and 10 kinds of material attributes were assigned,which met the requirements of finite element analysis.Moreover,it can be used to calculate bone density.OBJECTIVE:To explore a method for measurement of bone density based on three-dimensional reconstruction and finite element analysis.METHODS:A total of 11 specimens of femoral superior segment were selected.The mass of control group was firstly measured.The experimental groups were treated with thin-slice high resolution CT scan and three-dimensional reconstruction in Mimics 10.0,volume meshing in Ansys,assigned with 10,100 and 400 kinds of material attributes Mimics,exported to Ansys to calculat the volumes of the block elements of every types of material attributes.The mass and the density of the specimens was harvested according to the empirical formula concerning the gray value and the bone density.All results were treated with one-way ANOVA.RESULTS AND CONCLUSION:One-way ANOVA showed that there were no significant differences between control group and experimental groups assigned with 10,100 and 400 kinds of material attributes (P＞0.28),and there were no significantly among the experimental groups (P＞0.8).Results show that the method was able to measure the mass and the density of bone quantitatively,as well as the proportion between compact bone and cancellous bone;to assign 10 kinds of material attributes to three-dimensional model of femur could match the needs for measurements.The results can be used as an initial preparation for the unification of bone density and finite element analysis for osteoporosis.

BACKGROUND:Based on previously theoretical derivation,it thought that assignment with 10 kinds of material attributes to three-dimensional model of bone can match the needs of finite element analysis,however,whether the results is consistent with actual needs to be validated by experimental results.OBJECTIVE:Twelve specimens of femoral superior segment were used for finite element analysis,which were verified with results of biomechanical testing,to explore a reasonable method for material assignment of bone.METHODS:All 12 specimens of femoral superior segment were treated with CT scan,three-dimensional reconstruction in Mimics 10.0 and volume meshing in Ansys.The finite element analysis group was divided into 2 kinds (compact bone and cancellated bone),10,50,100,200,400 kinds of material attributes groups based on the gray value.All models were assigned with material attributes and tested in Ansys for mechanics data of nodes on surface of femoral neck.In biomechanical testing group,12 specimens of femoral superior segment were treated with compressed testing to harvest mechanics data of measuring point same as that of finite element analysis group.RESULTS AND CONCLUSION:The one-way analysis of variance showed that the differences between the biomechanical testing group and finite element analysis group of 2 kinds of material attributes had no obvious significance (P=0.082).Compared to the 10,50,100,200,400 kinds of material attributes group,the difference had no significance (P > 0.39).However,the differences between the 2 kinds of material attributes and the 10,50,100,200,400 kinds of material attributes in the finite element analysis group were obviously difference (P< 0.05),which was no difference in the 10,50,100,200,400 kinds of material attributes (P>0.9).The results demonstrated that to assign 10 kinds of material attributes to three-dimensional model of bone can match the needs of finite element analysis.

Objective To study the effects of early application of integrated traditional Chinese medicine (TCM)and western medicine and massage on the incidence and severity of pneumonia and prognosis in the therapeutic course of infants with cytomegalovirus(CMV)infection infantile cholestatic hepatopathy(ICH)accompanied by gastric volvulus(GV). Methods A prospective randomized controlled trial was conducted. 120 infants 1-6 months old with CMV infection ICH and complicated with GV inpatients were divided into treatment group and control group (each,60 cases). The TCM Lidanheji(consisting of artemisiae capillaris 30 g,weeping forsythia 30 g,Chinese goldthread 5 g,prepared rhubarb 5 g,unpeeled root of herbaceous peony 30 g,cassia 5 g,fruit of citron or trifoliate orange 10 g,large-headed atractylodes 10 g,fruit of Chinese magnoliavine 10 g,pangolin scale 3 g and licorice root 5 g)for oral administration or enema and ganciclovir intravenous injection were given to both groups. In the control group,based on the above treatment,postural and diet therapy,prokinetics(domperidone)were given in cases with GV. The massage treatment was only applied for treatment of GV in treatment group. The pneumonia in both groups was treated in accord to the conventional diagnosis and treatment for infantile pneumonia,bronchiolitis,severe pneumonia and the guide and management of infantile community acquired pneumonia. The total number of cases with pneumonia and its severity occurring before and after treatment in the course of the disease,the clinical therapeutic effects of ICH, GV and infantile pneumonia,the clinical physical signs,biochemical indexes and the time of hospitalization were observed and compared between the two groups. Results Compared with control group,after treatment the curative rate and total effective rate of ICH,GV,infant pneumonia in treatment group were significantly higher〔the curative rate of ICH:83.05%(49/59)vs. 71.93%(41/57),total effective rate:96.61%(57/59)vs. 91.23%(52/57);the curative rate of GV:72.88%(43/59)vs. 51.79%(29/56),total effective rate:96.61%(57/59)vs. 78.57%(44/56);the curative rate of infant pneumonia:81.08%(30/37)vs. 67.44%(29/43),total effective rate:100%(37/37)vs. 100%(43/43),P<0.05 or P<0.01〕. In the treatment group,the total number of cases with pneumonia occurring in the therapeutic course and the incidence of severe pneumonia were significantly less than those in the control group〔the occurrence of pneumonia:12 cases vs. 21 cases,the incidence of severe pneumonia:16.67%(2/12) vs. 42.86%(9/21),P<0.05 or P<0.01〕. The enlargement of liver and spleen,the level of total bilirubin(TBil), direct bilirubin(DBil),total bile acids(TBA)and alanine aminotransferase(ALT)in two groups after treatment were significantly lower than those before treatment,the changes being more marked in treatment group(P<0.05 or P<0.01). The time of stay in hospital in treatment group was remarkably shortened(days:21.32±3.26 vs. 27.38±6.09, P<0.05). Conclusion Early interference with combined TCM and western medicine and massage for treatment of infants with CMV infection ICH accompanied by GV can significantly decrease the incidence of pneumonia and its severity occurring in the disease course,therefore this therapeutic method is beneficial to the treatment and prognosis of infants with CMV infection ICH.
