RESUMO
OBJECTIVE@#To explore the effects of morphological changes such as vertebral wedge deformation and disc degeneration (collapse) on adult thoracolumbar/lumbar degenerative kyphosis(TL/LDK) deformity.@*METHODS@#A retrospective analysis of 32 patients with spinal TL/LDK deformity admitted from August 2015 to December 2020, including 8 males and 24 females, aged 48 to 75(60.3±12.4) years old. On the long-cassette standing upright lateral radiographs, the coronal Cobb angle, sagittal thoracic lumbar/lumbar kyphosis angle(KA) of spine were measured, and the height and wedge parameters of apex vertebral(AV) and two vertebrae(AV-1, AV-2, AV+1, AV+2) above and below AV and the intervertebrae and the intervertebral disc(AV-1D, AV-2D, AV+1D, AV+2D) were evaluated, involving anterior vertebral body height(AVH), posterior vertebral body height(PVH), vertebral wedge angle(VWA), ratio of vertebral wedging(RVW), anterior disc height(ADH), posterior disc height(PDH), disc wedge angle(DWA), ratio of disc wedging(RDW), and DWA/KA.@*RESULTS@#The average angle of kyphosis was (44.2±19.1)°. A significant decrease in anterior height of vertebral was observed compared to the posterior height of vertebral(P<0.005). There was no significant difference in anterior and posterior height of discs. The vertebral wedging ratio/contribution ratio:AV-2(14.98±10.95)%/(14.21±8.08)%, AV-1(21.08±12.39)%/(18.09±7.38)%, AV(26.94±11.94)%/(25.52±8.64)%, AV+1(24.19±8.42)%/(20.82±8.69)%, AV+2(20.56±7.80)%/(15.60±9.71)%, total contribution(94.23±22.25)%, the disc wedging ratio/contribution ratio:AV-2D(2.88±2.57)%/(5.27±4.11)%, AV-1D(1.98±1.41)%/(2.29±2.16)%, AV+1D(-5.54±3.75)%/(-0.57±0.46)%, AV+2D(-8.27±4.62)%/(-1.22±1.11)%, total contribution (5.77±4.79)%. And the contribution rate of AV was significantly higher than that of adjacent vertebral(P<0.05).@*CONCLUSION@#The vertebral body and intervertebral disc shape both have influence on thoracolumbar kyphosis. However, the contribution of vertebral morphometry to the angle of TL/LDK deformity is relatively more important than the disc. The contribution of the wedge change of the AV to the TL/LDK deformity is particularly significant.

OBJECTIVE@#To investigate the clinical effect of double plate combined with iliac bone graft in the treatment of femoral nonunion after intramedullary nailing.@*METHODS@#From December 2008 to December 2017, double plate combined with autogenous iliac bone graft was used to treat femoral nonunion after intramedullary nailing. There were 11 cases, including 10 males and 1 female, aged 35 to 62 years, and the time from fracture to nonunion was 12 to 20 months. According to Judet classification, there were 8 cases of atrophic nonunion and 3 cases of proliferative nonunion. Regular follow-up was conducted after operation to record the fracture healing time, load-bearing activity time and complications, and to observe the repair effect of double plate fixation combined with iliac bone graft on nonunion after femoral shaft fracture operation.@*RESULTS@#All patients were followed up for 12 to 22 months. The operation time was 70 to 130 min and the blood loss was 180 to 350 ml. After operation, 2 cases had knee stiffness, which recovered after passive exercise with CPM machine for 2 weeks;1 case had pain in iliac bone donor area, which was relieved after 3 months. The time of fracture healing was 24 to 40 weeks, and the time of complete weight-bearing activity was 14 to 32 weeks. SF-36 quality of life score at the final follow-up:body pain 70 to 82, activty 70 to 82, social function 72 to 83, the overall health 72 to 82. At the end of the follow-up, there were no complications such as limb shortening, infection, poor wound healing, internal fixation failure (fracture, loosening).@*CONCLUSION@#It is an effective method to treat nonunion of femur after intramedullary nailing by using double plate combined with autogenous iliac bone graft.

OBJECTIVE@#To investigate the risk factors of vertebral refracture after percutaneous kyphoplasty (PKP) for osteoprotic vertebral compression fractures (OVCFs), and to provide reference for clinical prevention.@*METHODS@#A retrospective analysis of 228 OVCFs patients who met the inclusion criteria admitted from November 6, 2013 to December 14, 2018. There were 35 males and 193 females, with a male-to-female ratio of 3∶20, and aged 58 to 91 years with an average of (69.70±7.03) years. All patients were treated with PKP and had complete clinical data. According to whether refracture occurred after operation, they were divided into refracture group (24 cases) and non refracture group (204 cases). Factors that may be related to refracture (including gender, age, surgical segment, number of vertebral bodies in the surgical segment, whether combined with degenerative scoliosis, whether anti-osteoporosis treatment) were included in the univariate analyses, and the single factor analysis of statistically significant risk factors was carried out with multiple Logistic regression analysis to further clarify the independent risk factors for vertebral body refracture after PKP. Survival analysis was performed using the time of vertebral refracture after PKP as the end time of follow up, the occurrence of refracture after PKP as the endpoint event, and the presence or absence of degenerative lateral curvature as a variable factor.@*RESULTS@#All 228 patients were followed up for 1.8 to 63.6 months with an average of (28.8±15.6) months, and the refracture rate was 10.5%(24/228). There were statistically significant differences between two groups in age, number of operative vertebral bodies, whether combinedwith degenerative scoliosis and whether anti osteoporosis treatment (@*CONCLUSION@#Combined scoliosis is an independent risk factor for refracture after OVCFs vertebroplasty, and it is also a possible high-risk factor for refracture after surgery.

OBJECTIVE@#To explore the clinical effect of bio lengthened stem arthroplasty replacement in the treatment of unstable intertrochanteric fractures in the elderly.@*METHODS@#From January 2015 to January 2018, 64 elderly patients with unstable intertrochanteric fractures were analyzed retrospectively. According to the surgical treatment, patients were divided into arthroplasty replacement group (bio-lengthened stem arthroplasty replacement) and internal fixation group (PFNA). In the arthroplasty group, there were 34 cases, including 19 males and 15 females, with an average age of (81.32±3.81) years old. The Evans classification of fracture was type Ⅲ in 15 cases, type Ⅳ in 16 cases and type Ⅴ in 3 cases. In the internal fixation group, there were 30 cases, including 14 males and 16 females, with an average age of (79.90±3.61) years old. The Evans classification of fracture was type Ⅲ in 10 cases, type Ⅳ in 15 cases and type V in 5 cases. X ray and CT showed unstable intertrochanteric fracture of femur. The operation time, intraoperative blood loss and complications were observed. Harris hip function score and SF-36 life quality score were used to evaluate the clinical effect.@*RESULTS@#All the incisions healed in stage Ⅰ. All patients were followed up for 13 to 39 months with an average of 23.4 months. The operation time and bleeding volume of the patients in the arthroplasty replacement group were more than those in the internal fixation group (<0.05). At the final follow-up, Harris function score of hip joint in the arthroplasty group was better than that in the internal fixation group (< 0.05);SF-36 life quality score in the arthroplasty group was better than that in the internal fixation group (<0.05).@*CONCLUSION@#The treatmentof unstable intertrochanteric fractures with bio-lengthened stem arthroplasty replacement and internal fixation can achieve good clinical results, but with bio-lengthened stem arthroplasty replacement, the postoperative complications are less, the function of hip joint is better, and the life quality and satisfaction of patients are higher.

OBJECTIVE@#To investigate the guiding significance of lumbar quantitative computed tomography (QCT) in percutaneous vertebroplasty (PKP) for osteoporotic vertebral compression fractures (OVCF).@*METHODS@#The clinical data of 90 patients with OVCF underwent PKP from December 2017 to December 2018 were retrospectively analyzed. There were 24 femalesand66males, withanaverage agedof (74.47±6.60) yearsold. Allpatientswere received QCT examination before surgery, andaccording to the QCT value oflumbarspine, the patientswere dividedinto osteopenia decrease group (80 to 120 g/L, 17 cases, 30 vertebrae), osteoporosis group (40 to 80 g/L, 44 cases, 66 vertebrae) and severe osteoporosis group (<40 g/L, 29 cases, 39 vertebrae). Bone cement was injected into vertebral body, AP and lateral X-rays were done during operation. The diffusion and leakage of bone cement in injured vertebrae of patients with different QCT values were observed. Unilateral approach was used for patients whose bone cement diffused beyond the midline of the vertebral body, otherwise, and bilateral approach was adopted, and guiding significance of QCT in PKP for OVCF was analyzed.@*RESULTS@#In 90 cases of 135 vertebrae, 72 cases of 98 vertebral bone cement diffused beyond the midline, accounting for 72.59%. Unilateral approach was used for the 72 patients whose bone cement diffused beyond the midline of the vertebral body, among them, there were 5 cases with 8 vertebrae in osteopenia group, 40 cases with 55 vertebrae in osteoporosis group and 27 cases with 35 vertebrae in severe osteoporosis group. There was significant difference in the bone cement dispersion between three groups (=41.397, =0.000). Moreover, no bone cement leakage occurred in osteopenia group, 3 cases of 4 vertebrae occurred in osteoporosis group and 2 cases of 3 vertebrae in severe osteoporosis group. However, none of the patients with bone cement leakage caused nerve injury and other symptoms, and there was no significant difference in bone cement leakage between the three groups (=2.242, =0.326).@*CONCLUSION@#According to the QCT examination of lumbar spine, defining the degree of osteoporosis and guiding the puncture method can shorten the operation time, reduce the number of fluoroscopy, and effectively improve the safety of vertebroplasty.

RESUMO
Objective To investigate the effect of cervical spinous process fracture with posterior ligamentous complex (PLC) injury on biomechanical stability of the goat cervical spine specimen in vitro, and evaluate the role of posterior structure in maintaining the stability of cervical spine. Methods Twenty-four fresh goat cervical spine C3-6 specimens were randomly and evenly divided into 3 groups: control group (group A), simple cervical spinous process fracture group (group B) and cervical spinous process fracture with PLC injury group (group C). Under loading of 1.5 N·m torque, the range of motion (ROM) in each group was respectively measured under 6 working conditions: flexion, extension, lateral bending and axial rotation, and the ROM differences among 3 groups were compared by using one-way ANOVA analysis. Results Simple cervical spinous process fracture had little effect on the stability of cervical spine and there was no significant difference in ROM between group B and control group (P>0.05) under all working conditions. Compared with control group, the ROM in flexion, extension and axial rotation significantly increased in group C (P0.05). Conclusions Simple cervical spinous process fracture does not affect the overall stability of cervical spine. Cervical spinous process fracture with PLC injury is more likely to cause cervical instability than simple cervical spinous process fracture, and surgical intervention is required in cervical spinous process fracture with PLC injury.
