ABSTRACT
Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
ABSTRACT
Objective@#To investigate the effects of fracture liaison service (FLS) model on the medication compliance of patients, quality of life, pain and re-fracture rate in patients with osteoporotic vertebral compression fracture (OVCF).@*Methods@#A prospective case control study was conducted to analyze the clinical data of 117 OVCF patients admitted to Department of Pain of Guizhou Provincial People's Hospital from January 2017 to September 2017. According to the random table method, patients were divided into control group (58 patients) and intervention group (59 patients). Routine nursing was adopted in the control group, and fracture liaison service mode was adopted in the intervention group on the basis of the control group until 3 months after discharge. Morisky scale was used to compare the medication compliance of patients on admission, at discharge, 1 month, and 3 months after discharge, and SF-36 was used to evaluate the quality of life. The SF-36 scale contained eight dimensions including physiological function, physiological performance, physical pain, overall health, vitality, social function, emotional function and mental health. Visual analogue scale (VAS) was used to evaluate the pain of patients. The re fracture rates of the two groups were compared.@*Results@#There were no significant differences between the two groups concerning gender, age, history of diabetes, history of hormone use, number of vertebral fractures, fracture site and cause of injury (P>0.05). In the intervention group, the medication compliance scores of patients in the first and third months after discharge were (5.5±2.0)points and (6.3±1.8)points, which were higher than those in the control group [(3.5±2.2)points and (3.3±1.8)points] (P<0.05). Within each group, there were significant differences among the medication compliance scores at the different time points of evaluation (on admission, at discharge, 1 month, and 3 months after discharge). The scores of the eight dimensions of the SF-36 scale in the intervention group were higher than those in the control group at 1st and 3rd months after discharge (P<0.05). Within each group, there were significant differences among the SF-36 scores at the different time points of evaluation. The pain scores of the intervention group at discharge and 1st and 3rd months after discharge were ( 3.1±1.7)points, (1.8±1.3)points, (1.4±1.3)points, all lower than those in the control group [(5.2±1.7)points, (3.6±1.6)points, (2.7±1.8)points] (P<0.05). Within each group, there were significant differences among the pain scores at the different time points of evaluation. At 1st and 3rd months after discharge, the re-fracture rates of the intervention group were both 2%, and the those of the control group were 3% and 9%, respectively, showing no significant difference between the two groups (P>0.05).@*Conclusion@#The FLS model can effectively alleviate the pain of OVCF patients, improve the medication compliance and quality of life of patients after discharge, but it cannot reduce the short-term re fracture rate after discharge.

ABSTRACT
Introduction:One of the most common dental procedures associated to vertical root fractures is the endodontic treatment with excessive dentin wall wear and another increasing risk factor is the use of intraradicular post. Objective: This study evaluated the resistance to fracture of the buccal and palatal roots of maxillary first premolars with endodontically treated canals and spaces for posts. Material and methods: Twenty two first permanent premolar roots (11 buccal and 11 palatal) composed the experimental sample. The canals were prepared with Protaper Universal® system until file F3 and then filled with gutta-percha cone F3 and endodontic sealer and received spaces for posts keeping 4 mm of filling at the apical third. The roots were subjected to compression test in a universal testing machine (Kratus). The roots were subjected to a progressive compression stress at a speed of 0.5 mm / min. A load cell of 200 kg was used. Results: Statistical analysis revealed significant differences between the strength values and resistance limit between groups (P<0.05), as analyzed by t Student test. The values of resistance to fracture of 0.44 kgf/mm2 for group 1 (buccal roots) and 0.31 kgf/mm2 for group 2 (palatal roots) were found. Conclusion: The resistance to fracture of the buccal roots was higher than that of palatal roots of first premolars submitted to biomechanical preparation and root preparation for intraradicular post.
ABSTRACT
Objective:To investigate the clinical characteristics of vertebral compression fracture ( VCF) in glucocorticosteroid-induced osteoporosis ( GIOP) and risk of vertebral refracture after percuta-neous vertebroplasty ( PVP) or percutaneous kyphoplasty ( PKP) .Methods:In the study, 570 cases who received PVP or PKP as treatments of VCF from January 2010 to December 2013 were retrospective re-viewed, of which 42 were GIOP and 21 were followed up as GIOP group, and the other 528 were primary osteoporosis and 391 were followed up, of which 84 were selected as Control group based on age and gen-der.The fracture location, ratio of single segment fracture and multiple segments fracture in the two groups were compared.In the final follow up, the reoperation rates for vertebral refractures by the Kap-lan-Meier method in the two groups were compared.Results:The follow up periods were (24.0 ±13.1) months in GIOP group and (25.8 ±14.4) months in control group(P>0.05).In GIOP group, there were 11 cases with one-segment fracture, 2 with two-segments fracture, 3 with three-segments fracture, 2 with four-segments fracture, 2 with five-segments fracture and 1 with eight-segments fracture.In Control group, there were 67 cases with one-segment fracture, 12 with two-segments fracture, 3 with three-seg-ment fracture, and 2 with four-segments fracture.The ratio of single segment fracture in GIOP group was significantly lower than that in Control group(52.4% vs.79.8%,P=0.01).There were 50 fracture segments in GIOP group and 109 fracture segments in Control group.The ratios of fracture segments loca-ted in thoracic segments(T1-T10), thoracolumbar segments(T11-L1)and lumbar segments(L2-L5) were 18%, 46%and 36% in GIOP group and 11.9%, 58.7% and 29.4% in Control group ( P >0.05).The refracture rate in GIOP group was higher than that in control group (23.8%vs.6.0%).The survival rate was lower in GIOP group than that in control group ( Pthoracic segments>lumbar segments).The risk of multiple segments VCF was higher in GIOP than in primary osteoporosis. The risk of vertebral refractures after PVP or PKP was higher in GIOP than in primary osteoporosis.
ABSTRACT
Objective To retrospectively review the clinical experience of percutaneous kyphoplasty (PKP) in the treatment of severe osteoporotic vertebral compression fracture (OVCF) during 10 years,and to propose a new classified treatment for OVCF.Methods 1200 patients with osteoporotic thoracolumbar vertebral compression fracture underwent percutaneous kyphoplasty from Aug.2003 to Aug.2013.There were 62 severe patients (5.2％,81 vertebraes),aged from 69 to 95 years (average 76.5 years),with 66.7％ to 78.9％ (average 71.3％) of vertebral body compression.Patients were followed up for 12 to 120 months (average 78 months).According to the preoperative imaging data,the fractures were classified into four types:simple type,pseudarthrosis type,cavern type,progressive type.Individualized PKP was performed on each patient.Results All the patients tolerated procedure well.The visual analogue scale (VAS) was reduced from (7.2± 2.1)preoperatively to (2.5±1.7) 3 days after PKP(t=13.197,P＜0.01).The Medical Outcomes Study (MOS) 36-Item Short Form Health Survey (SF-36) scales was improved from (29.5±8.2) to (46.5±9.9) 3 days after surgery(t=22.884,P＜0.01).Most patients were satisfied with the efficacy.The anterior height of vertebral body was increased from (14.21±2.44) mm preoperatively to (19.28 ±4.37) mm 3 days after surgery(t=9.108,P＜0.01).The Cobb angle were decreased from (16.45 ± ±5.37)° to (9.41±4.13)° 3 days after surgery(t=9.355,P＜0.01).The height of vertebrae was lost and the kyphosis angle aggravated with the follow-up time.New vertebral fractures were found in 21 patients (21/62,33.9％) at the last follow-up.Conclusions The preoperative accurate classification of severe osteoporosis vertebral compression fracture and individualized PKP can raise the successful operation rate and reduce the incidences of complications.
ABSTRACT
STUDY DESIGN: Retrospective propensity score-matched cohort analysis of the Thomson Reuters MarketScan database. PURPOSE: To compare the outcomes of vertebral compression fracture (VCF) treatment options, with an emphasis on reoperation, complications, costand overall healthcare resource use between 2005 and 2009 in the United States. OVERVIEW OF LITERATURE: Options for the treatment of VCFs include conservative management, kyphoplasty, and vertebroplasty. The cost-effectiveness of surgical intervention for VCF has been criticized, and some suggest their outcomes to be similar to placebo. METHODS: Patients 18 years of age and older who developed a VCF were identified and separated into three treatment cohorts: vertebroplasty, kyphoplasty, and non-surgical. Propensity score matching was performed to match patients between cohorts. Main outcomes assessed included reoperation, complications, healthcare resource use and associated cost. Outcomes were compared at three separate time intervals (patients at index hospitalization; patients with at least 2-year follow-up data; and those with at least 4-year follow-up data). RESULTS: Twenty thousand seven hundred forty patients were identified with VCFs, yielding 7,290 after propensity score matching. The mean age of the patients was 78+/-12 years; and 5,507 (75.5%) were female. All reoperation rates ranged from 6%-17%, while complication rates ranged from 7%-10%, which did not differ significantly among the three cohorts at all follow-up periods. Overall costs were noted to be significantly greater in both the kyphoplasty and vertebroplasty groups at 1-year follow-up, not at 2-year and 4-year follow-up. CONCLUSIONS: Our data suggests that the treatment of a VCF patient will likely be associated with similar long-term operative and complication rates regardless of treatment modality.

Objective To research the risk of osteopo'rotic vertebral fractures with PKP after the PMMA injected location and dose of occurrence of vertebral refracture.Methods 78 cases of vertebral osteoporotic thoracolumbar vertebral compression fracture patients with PKP treatmentin were selected.According to position of postoperative PMMA in the vertebral body,they were divided into the side of the group of 35 patients and a median group of 43 patients.Compared two groups of patients before and after surgery,VAS,ODI score,the SI and Cobb angle and analyzed the PMMA leakage occur with the relationship of the amount of bone cement injected.Results There were significant differences in visual analogue pain scale(VAS),Oswestry disability index(ODI),sagittal index(SI) and Cobb angle of each group preoperatively versuspostoperatively (all P ＜ 0.05).No statistical difference was noted in the VAS,ODI,SI and Cobb angle between two groups preoperatively versus postoperatively(all P ＞ 0.05).PMMA injection volume between the the leakage group and the non-leakage patients had statistically significant difference (P ＜ 0.05).Conclusion PKP could obtain better clinical therapeutic effect in osteoporotic vertebral fractures treatment.Different PMMA positions had no significant influence on the therapeutic results.PMMA injected dose is a risk factor for bone cement leakage,which will increase the risk of vertebral fractures again.
ABSTRACT
ObjectiveTo investigate and compare the efficacy, safety, and cost effectiveness in the treatment of painful osteoporotic vertebral compression fractures ( OVCFs ) with percutaneous vertebroplasty (PVP) and kyphoplasty(PKP). MethodsSeventy-two patients (96 vertebrae) with painful OVCFs were treated by PVP (n ＝34) or PKP (n ＝38) under radiological monitoring. After bone biopsy needle into the compressed vertebra, bone cement (polymethylmethacrylate) was injected in PVP group, and that was inserted followed by the inflation of vertebra to create cavities in PKP group. The fluoroscopy time, total amount of bone cement injected, and cost were recollected respectively. The score of visual analogue scale point( VAS, 10-point scale)was determined at before the procedures, and 24 hours, one week, and one month after the procedures.Pain relief and complications were observed.The Cobb angle and vertebral heights of the anterior, middle, and posterior border were measured pre-and post-operative. ResultsThe two procedures were technically successful in all patients. The follow-up ranged from 1. 0 to 34. 0 months [mean time, (8. 9 ±3.2) months]. The Mean fluoroscopy time of treating per vertebra in PVP group was ( 11. 1 ± 10. 6 ) min, which was significant shorter than that ( 23.5 ± 13. 0) min in PKP group( P ＜0. 05 ).The mean total cost per patient was (5127. 2 ± 502.3 ) yuan in PVP group, which were strikingly lower than that(32 301.4 ±3204. 6) yuan in PKP group (P ＜0. 05).(3)There was no significant difference( P ＞0. 05 ) in average cement volumes in PVP group [ (4. 9 ± 1.1 ) ml]and PKP group [ (5.4 ± 1.7 ) ml]. Pain relief of was observed in 94. 1％ (32/34) of PVP group and in 92. 1％ (35/38) of PKP group. The score of VAS at pre-operation was (8. 3 ±0. 4 vs 7.9 ±0. 8) ,and at post-operative 24 h (2. 9 ±0. 9 vs 2. 8 ± 1. 2),1 week (2.6 ± 0. 9 vs 2.6 ± 1. 1 ), and 1 month (2.6 ± 0. 9 vs 2. 5 ± 1.3 ) were no difference at PKP and PVP group(P ＜0.05). There was significant difference between pre- and post-operative time point in each group. The Cobb angle, anterior and middle height of vertebra was corrected in both PVP and PKP group. In PVP group, the preoperative Cobb angle, anterior and middle height of vertebra was (24. 2 ± 3.8 )°,( 19. 1 ± 1.4) mm, (25. 2 ± 1.0) mm, which was significant different ( P ＜ 0. 05 ) from that of ( 19.4 ±3.9)°, (21.0 ± 1.5) mm, (27.0 ± 1.2) mm at pre-operation.In PKP group,there was significant difference (P ＜ 0. 05 ) in the preoperative Cobb angle, anterior and middle height of vertebra [(25. 1 ±5.0)°vs(10.7 ±2.8)°, (19.5 ± 1.5) mm vs (24.3 ± 1.9) mm, (25.4 ± 1.1) mm vs (29.7 ±1.3) mm, respectively]. As to the above index, the overall correcting effect in PKP was much better than that in PVP( P ＜0. 05 ). Cement leakage occurred in 9 cases in PVP group and 3 cases in PKP group ( P ＜0. 05 ) but no symptoms. There were no major complications during operation in the two groups. Conclusion PVP and PKP are effective and safe in the treatment of painful OVCFs but PVP is more cost effective than PKP.
ABSTRACT
Objective To investigate the features of intravertebral vacuum phenomenon (IVP)in vertebral compression fractures (VCFs). Methods Two hundred and nine patients with VCFs underwent percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP). The biopsies and the images of X-ray, CT, MRI of VCFs were obtained. The consistency between IVP and osteonecrosis on histology and the positive predictive value (PPV), negative predictive value (NPV), sensitivity, specificity and Youden index of IVP for diagnosing local osteonecrosis in VCFs were analyzed. Fisher exact probability test was used to analyze the coherence between IVP and osteonecrosis. Results Histological examination revealed 146(69.9%) osteoporoses, 10 (4.8%) osteonecroses with osteoporoses, 53 (25.4%) neoplasms. Prior to surgery,10 cases of IVP were found. Plain radiograph showed horizontally oriented lucent cleft in the vertebral body;CT further confirmed the location of gas;T_1-weighted MR image appeared hypointensity,while the signal intensity of T_2-weighted MR image differed, depending on the duration of recumbency. Nine of 10 patients with IVP showed osteonecrosis on histology, while 9 of 10 patients with osteonecrosis contained IVP. The association of osteonecrosis on histology and the IVP was statistically significant(P <0.01). The PPV, NPV, sensitivity, specificity, and Youden index for diagnosing local osteonecrosis was 90% (9/10), 99.5% (198/199), 90.0% (9/10), 99.5% (198/199), and 0.9, respectively. Conclusion The IVP is stongly suggestive of local osteonecrosis in vertebral compression fracture.
ABSTRACT
Objective To evaluate the curative effect and complications of percutaneous puncture kyphoplasty in the treatment of vertebral compression fracture in the elderly. Methods 19 cases of vertebral compression fracture in the elderly patients with disc 25 PKP technology applications were diagnosed with the accurate positioning,local anesthesia a small incision of about 0. 3cm later puncture path through vertebral pedicle to the wound vertebra,After perspective is the accurate lateral, putting into high-pressure balloon, injecting the contrast agent into the balloon with high-pressure syringe gradually. The wound vertebra is blackmai until a high degree of vertebral distraction to the recovery basis under the C-arm, and then taking the balloon out after pumping the contrast agent out. Bone cement is mixed well and injected into the cavity of the wound vertebra slowly which is the result of balloon dilation,during that time under the control of bone cement inside the wound vertebra,then puting the working column out and surgery completed. Results The low back pain of 19 patients immediately disappeared or significantly reduced after the operation, and 8 postoperative patients is up that day, 11 cases is up the following day. The degree of the wound vertebra is recovered by X-ray examination, and the bone cement evenly distributed within the wound vertebra, no spills. This group of patients are followed up for an average of 18 months(1 ～24 months) ,using visual analog and digital method to determine changes in Iow back pain. The data are paired t test,P ＜ 0.01. It have significant difference of views.Conclusion Percutaneous kyphoplasty accurate cervical disc herniation and effective disarmament of the symptoms and signs, with trauma and rapid recovery, fewer complications, shorter course of treatment and so on, and it is a safe and effective way in the treatment of vertebral compression fracture in the elderly.
ABSTRACT
Objective To estimate the clinical value of percutaneous vertebroplasty (PVP)performed on the elderly patients aged 80 years and over with osteoporotic vertebral fractures.Methods Since January 2000, 19 patients aged 80 years and over were treated with PVP, and 17 patients from 60 to 79 years old underwent percutancous kyphoplasty (PKP). Visual analogue scale (VAS) was tested preoperatively and 1 to 7 days, 3 months, 6 months, 1 year and 2 years after operation. The time of radiation, volume of bone cement injection and hospital charges were compared betwecn two procedures. Results Over the 2-year follow-up, there were no significant differences in analgesia effects between thc two groups (P＞0.05). The radiation time of PVP and PKP was (107±37)s and (151±76)s respectively (t=2.24, P＜0.05). The hospital charges of PVP and PKP were ￥(16 124±5850) and ￥(34 265±6655) respectively (t=9.26,P＜0.01). Conclusions PVP is better than PKP for treating osteoporotic compression fractures in the elderly patients over 80 years, because of the former's simplicity and efficiency.
ABSTRACT
Objective To explore the clinical effect of the percutaneous vertebroplasty(PVP) and filling auto-solidification calcium phosphate cement(CPC) in treatment of osteoporotic thoracolumbar vertebral fractures. Methods From January, 2004, 26 patients with osteoporotic thoracolumbar vertebral compression fracture (29 vertebral bodies) were treated with intraoperative manipulative reduction, PVP and filling auto-solidification CPC. Results PVP were successfully performed with unilateral or bilateral vertebral pedicles for the 29 vertebrae. The average injection dose of CPC was 4.6 mL. CPC leakage occurred during the procedure in 5 vertebrae of 5 cases. All the patients were followed up for 3 to 8 months (averaging 4.6 months) and experienced complete pain relief. There was no severe complication related to the treatment. Except in 3 patients who lost 15%of the vertebral body height, the anterior height of the injured vertebral body in the other 23 patients recovered averagely to 80%of the normal one. Conclusion PVP with filling auto-solidification CPC is safe and effective in the treatment of osteoporotic thoracolumbar vertebral compression fractures.
