ObjectiveTo explore the safety and preliminary effectiveness of transintervertebral release, bone impaction grafting, and posterior column compressed-closing in the treatment of osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis.MethodsThe clinical data of 21 elderly patients with osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis were retrospectively analyzed between March 2016 and November 2017. There were 1 male and 20 females, aged 55-75 years, with an average of 64.8 years. The disease duration was 8-24 months, with an average of 13.1 months. The bone density T value ranged from −3.4 to −2.1, with an average of −2.3. Lesion segments: T11 in 2 cases, T12 in 6 cases, L1 in 8 cases, L2 in 1 case, T11, 12 in 1 case, T12, L1 in 2 cases, and T12, L2 in 1 case. Preoperative neurological function was classified according to the American Spinal Injury Association (ASIA): 5 cases of grade D and 16 cases of grade E. All patients underwent transintervertebral release, bone impaction grafting, and posterior column compressed-closing. The effectiveness was evaluated by visual analogue scale (VAS) score and Oswestry dysfunction index (ODI) score before operation, at 3 months after operation, and at last follow-up. The neurological function was assessed by ASIA at last follow-up. Local kyphosis Cobb angle (LKCA), thoracic kyphosis (TK), lumbar lordosis (LL), and sagittal vertebral axis (SVA) were measured on the X-ray films of the full-length lateral spine of the patient before operation, at 1 week after operation, and at last follow-up.ResultsNo complication such as fracture of internal fixator or nerve injury occurred. LKCA, TK, and SVA were significantly improved at 1 week after operation and at last follow-up (P<0.05). There was no significant difference between at 1 week after operation and at last follow-up (P>0.05). There was no significant difference in LL before and after operation (F=3.013, P=0.057). The VAS and ODI scores were significantly improved at 3 months after operation and at last follow-up, and further improved at last follow-up when compared with the scores at 3 months after operation, showing significant differences between time points (P<0.05). Five patients with ASIA grade D neurological function recovered to grade E at 6 months after operation.ConclusionTransintervertebral release, bone impaction grafting, and posterior column compressed-closing for treating osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis has definite effectiveness, strong orthopaedic ability, and minimal trauma, which can effectively restore the sagittal balance of the spine, alleviate pain, and improve the patients’ quality of life.

ObjectiveTo summarize the progress of the surgical selection of fusion levels for degenerative scoliosis. MethodsThe domestic and foreign related literature about degenerative scoliosis, including clinical features, classification, surgical treatment, and the fused segment, was summarized. ResultsDegenerative scoliosis is very complicated. Short segment fusion and long segment fusion are the main surgical types. The long segment fusion is better in terms of reconstructing the stability of spine; however, it has more related complications. The short segment fusion has been used widely in clinical, but it causes degenerative disease easily. W/AL value can be used to direct the selection of short or long segment fusion for degenerative scoliosis. ConclusionThe key to success surgery is choosing reasonable fused segment. Now there is no unified selection standard. With more knowledge about degenerative scoliosis, greater development can be expected in the future.
ObjectivesTo systematically review the proportion of Tregs in peripheral blood of patients with ankylosing spondylitis (AS) and its relationship with Treg's diffrent phenotypes.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect case-control studies on peripheral Tregs of AS patients from inception to November 31st, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 61 case-control studies involving 2 466 AS patients and 1 879 controls were included. The results of meta-analysis showed that: the proportion of peripheral Tregs of patients with AS was significantly lower than that of the normal control (SMD=−0.905, 95%CI −1.294 to −0.517, P<0.000 1), and the proportion of Tregs in the disease-active group was significantly lower than that in disease-inactive group (SMD=−0.928, 95%CI −1.431 to −0.425, P<0.000 1). The proportion of CD4+CD25+FOXP3+Tregs and CD4+CD25+CD127low/−Tregs were lower in AS patients than that in control subjects (SMD=−2.547, 95%CI −3.521 to −1.573, P<0.000 1; SMD=−0.709, 95% CI −1.056 to −0.362, P<0.000 1). The proportion of Tregs defined by CD4+CD25low/−FOXP3+ was higher in AS patients (SMD=0.683, 95%CI 0.161 to 1.206, P=0.01). There was no significant difference betweew other phenotypes of Tregs groups.roups.ConclusionsThe reduction of Tregs may be one of the important reasons for the occurrence and development of AS, which may provide a new approach for the diagnosis and treatment of AS.
Objective To review the research progress of the vacuum phenomenon in spine. Methods The recent articles about the vacuum phenomenon in spine were reviewed; the features of imaging and the cl inical correlation were summarized. Results The vaccum phenomenon has been described in every segment of the spine. This phenomenon occurs mostly to the disc space and represents a transparent area on radiograph. Conclusion The causes of the vacuum phenomenoninclude degeneration of the anatomic structures of spine, trauma, and other pathologic changes. The vacuum phenomenon has important diagnostic and cl inical significances.
Objective To explore the current status of preoperative hope level and its influencing factors in scoliosis patients, focusing on the role of medical coping, social support and self-care ability on the hope level, and to provide a basis for optimising perioperative psychological interventions. Methods Preoperative scoliosis patients at West China Hospital of Sichuan University between January 2024 and January 2025 were selected. Patients were included in the survey using a general information questionnaire, Herth Hope Index (HHI), Medical Coping Questionnaire, Social Support Rating Scale (SSRS), and Daily Living Ability Scale. Multiple linear regression analyses were performed and influential factors were explored with HHI score as the dependent variable. Results A total of 156 patients were investigated. Among them, there were 104 females (66.67%); The average HHI score was (36.88±4.04) points; 41.03% (64 cases) of patients were at a low to moderate hope level (HHI≤35 points). There were statistically significant differences in HHI scores among patients with different marital statuses and disease durations (P<0.05). The correlation analysis results showed that social support was positively correlated with HHI (r=0.207, P=0.010); Medical coping (r=−0.015, P=0.852) and self-care ability (r=0.010, P=0.903) were not correlated with HHI. The results of multiple linear regression analysis showed that the total SSRS score affected the HHI score of preoperative scoliosis patients (P=0.040). Conclusion Multidisciplinary interventions should be implemented for patients with low levels of hope, focusing on married patients with a disease duration of 1-5 years, and improving their level of hope by strengthening the social support network.
ObjectiveTo investigate the effect of acute non-isovolemic hemodilution (ANIH) on spinal surgery. MethodsFrom January 2012 to July 2013, 80 patients scheduled for spinal surgery were enrolled. The patients were randomized into four groups, with 20 in each group. Patients in group A were infused with Ringer's injection and polygeline for fluid loss, physiological needs and blood loss. In group B, the patients were infused with acute hypervolemic hemodilution. In group C, patients were infused with acute nomovolemic hemodilution. In group D, patients were infused with ANIH. The hemodynamics and arterial blood gas indexes were detected in all the patients. ResultsThe mean blood pressure in group A and C was significantly more stable than that in group B and D. The central vein pressure in group B and D was significantly higher than that in group A and C after hemodilution (P<0.05), while the hematocrit in group B and D was significantly lower than that in group A and C (P<0.05). Allogeneic blood transfusion was performed in group A and B, while it was not performed in group C and D. ConclusionANIH can reduce the volume of blood loss during spinal surgery, and it is safe.
