ABSTRACT

Objective:To examine the correlation between intraoperative pain scores during puncturing and postoperative complications in elderly patients with osteoporotic vertebral fractures(OVF)treated with vertebroplasty(VP).Methods:In a retrospective case-control study, clinical data of 326 patients with single-segment OVF treated with VP, including 42 patients(12.9%)(the complication group)with complications within 1 month of surgery and 284 patients(87.1%)without complications(the control group), were compared.Changes in patient numerical evaluation scale(NRS)scores were recorded and compared for the complication group and the control group at different time points, which concluded preoperative(T0), intraoperative puncturing of soft tissues(T1), bone puncturing(T2), bone cement injection into the vertebral body(T3), 24 hours(T4), 1 month(T5)and 3 months(T6)after surgery.Results:NRS scores for patients in the complication group vs.those in the control group at different phase were(5.78±2.11 vs.6.10±2.21)points at T0, (7.59±1.46 vs.4.63±0.86)points at T1, (7.30±1.35 vs.5.14±1.07)points at T2, (6.97±1.24 vs.6.11±1.58)points at T3, (4.09±0.82 vs.2.19±0.87)points at T4, (2.07±0.80 vs.1.93±0.78)points at T5, and(1.83±0.72 vs.1.74±0.65)points at T6, but there was no significant difference between the two groups at T0( P>0.05).The complication group had higher NRS scores than the control group at T1, T2, T3, and T4(all P<0.05).For intra-group comparisons, both the complication group and the control group showed statistically significant differences between T0 and T4, between T0 and T5, and between T4 and T5(all P<0.05). Conclusions:Elderly OVF patients who are treated with VP and exhibit post-surgery complications often experienced severe pain during surgery, and an NRS score greater than 7 may be an independent risk factor for postoperative complications of VP.Effort should be made to avoid or reduce complications related to surgery, reduce pain and improve treatment outcomes of VP for elderly patients.

ABSTRACT

Objective:To investigate the risk factors of bone cement leakage after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture (OVCF).Methods:A multi-center, large-sample, case-control study was carried out to analyze the clinical data of 2 273 OVCF patients (2 689 vertebrae) undergone PVP at four hospitals between May 2018 and October 2021, including 994 males and 1 279 females, with the age of 52-91 years [(69.1±3.1)years]. Of all, 581 patients (604 vertebrae) were allocated to leakage group and 1 692 patients (2 085 vertebrae) to no leakage group according to the occurrence of bone cement leakage. The gender, age, fracture sites, vertebral compression degree, endplate integrity of fractured vertebrae, surgical segments, surgical approaches and bone cement injection volume were recorded. Univariate analysis was used to investigate the correlation between those indicators with bone cement leakage. Multivariate Logistic regression analysis was used to identify the independent risk factors for bone cement leakage.Results:Univariate analysis showed that gender, age, fracture sites, vertebral compression degree, bone cement injection volume were related to bone cement leakage after PVP ( P<0.05 or 0.01), but no correlation was found in the endplate integrity of fractured vertebrae, surgical segments and surgical approaches (all P>0.05). Multivariate Logistic regression analysis showed that fracture sites ( OR=1.68, 95% CI 1.11-2.55, P<0.05), vertebral compression degree more than 40% ( OR=1.98, 95% CI 1.29-3.02, P<0.01), bone cement injection volume greater than or equal to 5.5 ml ( OR=1.55, 95% CI 1.07-2.26, P<0.05) were significantly associated with bone cement leakage after PVP. Conclusion:Thoracic vertebral fracture, vertebral compression degree more than 40% and bone cement injection volume greater than or equal to 5.5 ml are independent risk factors for bone cement leakage after PVP in OVCF.

ABSTRACT

Objective:To compare the clinical effects of percutaneous curved vertebroplasty (PCVP) and unilateral percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective cohort study was used to analyze the clinical data of 104 patients with single vertebral OVCF treated in Tianjin Hospital from September 2019 to September 2020, including 21 males and 83 females; aged 50-91 years [(70.3±7.7)years]. AO classification of the fracture was type A1 in 65 patients and type A2 in 39. The patients received PCVP (PCVP group, n=51) or unilateral PKP surgery (unilateral PKP group, n=53). The operation time, bone cement injection volume, intraoperative fluoroscopy frequency, effective dispersion times of bone cement and excellent rate of bone cement distribution were compared between the two groups. In evaluation of the therapeutic effects of the two groups, visual analogue scale (VAS) and Oswestry dysfunction index (ODI) were measured preoperatively and at postoperative 24 hours, 3 months and 6 months; Beck index was measured preoperatively and at postoperative 24 hours and 3 months. The rate of bone cement leakage and rate of refracture of adjacent vertebral bodies were compared between the two groups. Results:All patients were followed up for 6-8 months [(6.4±0.7)months]. The operation time, bone cement injection volume and intraoperative fluoroscopy frequency in PCVP group was (12.15±1.63)minutes, (2.13±0.28)ml and (24.74±1.71)times, shorter or less than (22.09±1.62)minutes, (5.30±0.52)ml and (30.09±1.86)times in unilateral PKP group (all P<0.01). The effective dispersion times of bone cement in PCVP group was (1.42±0.04)times, higher than (1.18±0.02)times in unilateral PKP group ( P<0.01). The excellent rate of bone cement distribution in PCVP group was 94%, higher than 70% in unilateral PKP group ( P<0.01). There were no significant differences in VAS, ODI and Beck index between the two groups before operation and at 24 hours and 3 months after operation (all P>0.05). VAS and ODI in PCVP group were (1.20±0.49)points and 16.52±5.22 at 6 months after operation, lower than (1.49±0.58)points and 20.16±5.16 in unilateral PKP group (all P<0.01). VAS and ODI in the two groups were significantly improved at 24 hours, 3 months and 6 months after operation when compared with those before operation (all P<0.05). Beck index in the two groups detected at 24 hours and 3 months after operation was improved from that before operation (all P<0.05). Unilateral PKP group showed Beck index was 0.75±0.07 at 3 months after operation, significantly lower than 0.79±0.07 at 24 hours after operation ( P<0.05), but there was no significant change in PCVP group ( P>0.05). The leakage rate of bone cement in PCVP group was 16% (8/51), lower than 47% (25/53) in unilateral PKP group ( P<0.01). There was no significant difference in the incidence of refracture of adjacent vertebral bodies between the two groups during follow-up ( P>0.05). Conclusion:For OVCF, PCVP is superior to unilateral PKP in terms of operation time, amount of bone cement injection, intraoperative fluoroscopy frequency, dispersion effect of bone cement in vertebral body, pain, function improvement, maintenance of injured vertebral height and incidence of bone cement leakage.

ABSTRACT

The incidence of acute symptomatic thoracolumbar osteoporotic compression fractures (ASTOCFs) has increased significantly with population aging in China. Vertebral augmentation has been widely used because of its minimally invasive, safe and effective characteristics. However, many problems in the diagnosis and treatment of ASTOCFs remain controversial. In order to standardize the diagnosis and treatment of ASTOCFs, the editorial board of "Chinese Journal of Trauma "and expert panel of Spinal Trauma Committee of Orthopedics Branch of Chinese Medical Doctor Association formulated the"clinical guidelines for vertebral augmentation for acute symptomatic thoracolumbar osteoporotic compression fractures" (hereafter referred to as the "guideline"). The guideline provided evidence-based recommendations on key issues regarding the use of vertebral augmentation in such fracture. Since orthopedic surgeons at different levels of medical institutions have different understanding of the guideline, the authors made an in-depth interpretation of some key points in the guideline to help clinicians better understand the guideline and guide clinical practice.

ABSTRACT

Objective:To investigate the efficacy of the novel bone cement bridging screw system combined with percutaneous vertebroplasty (PVP) in the treatment of symptomatic chronic osteoporotic vertebral fractures (SCOVF) with intravertebral vacuum cleft (IVC).Methods:A retrospective case series study was used to analyze the clinical data of 27 patients with SCOVF admitted to Honghui Hospital affiliated to Xi′an Jiaotong University from August 2016 to August 2018, including 6 males and 21 females; age 69-88 years [(75.2±4.9)years]. All patients were treated by the novel bone cement bridging screw combined with PVP. The operation time, amount of bone cement injected and occurrence of bone cement leakage or displacement were recorded. The vertebral body index (VBI), vertebral body angle (VBA), two-segment Cobb angle (BCA), visual analogue score (VAS) and Oswestry disability index (ODI) were compared preoperatively, at day 1 after operation and at the last follow-up. The results of the MOS 36-item short form health survey (SF-36) and Odom′s criteria were compared preoperatively and at the last follow-up to evaluate pain relief and neurological recovery.Results:All patients were followed up for 36-48 months [(40.2±3.7)months]. The operation time was 37-70 minutes [(49.6±10.8)minutes], with the amount of bone cement injected for 3-6 ml [(34.7±0.9)ml]. Intraoperative bone cement leakage occurred in 4 patients (15%), among which 3 had lateral vertebral leakage and 1 superior intervertebral disc leakage. There was no bone cement displacement during the postoperative period to the last follow-up. The VBI, VBA, BCA, VAS and ODI were (43.1±5.9)%, (21.0±2.6)°, (45.0±6.3)°, 7.6 (7.0, 8.0)points, (79.9±7.6)% preoperatively, were (78.7±2.6)%, (12.7±2.1)°, (26.1±4.7)°, 3.2 (3.0, 4.0)points, (50.0±9.3)% at day 1 after operation, and were (78.0±2.3)%, (13.2±2.4)°, (27.1±4.9)°, 2.0 (2.0, 2.0)points, (22.9±5.1)% at the last follow-up. There were significant differences in above five measures at day 1 after operation and at the final follow-up in comparison with the preoperative values (all P<0.05), and their values measured at day 1 after operation and at the final follow-up were also significantly different (all P<0.05). The SF-36 score in physical function, role physical, body pain, vitality and social function was 45.2 (40.0, 50.0)points, 28.7 (25.0, 50.0)points, 15.9 (10.0, 22.0)points, 48.3 (40.0, 60.0)points, 29.2 (25.0, 37.5)points preoperatively, significantly different from 78.0 (75.0, 85.0)points, 75.0 (75.0, 75.0)points, 68.1 (64.0, 74.0)points, 62.0 (55.0, 70.0)points, 34.7 (25.0, 37.5)points at the last follow-up (all P<0.05). However, there were no significant differences in SF-36 before operation and at the last follow-up in dimensions of general health, emotional function and mental health (all P>0.05). According to Odom′s criteria, 19 patients were graded as excellent, 7 good, 1 fair and 0 poor, with an excellent and good rate of 96%. Conclusion:For SCOVF patients with IVC, the novel bone cement bridging screw system combined with PVP has advantages of no displacement of bone cement, satisfactory fixation, significant pain relief and satisfactory functional recovery.

ABSTRACT

With the large use of vertebral augmentation in the treatment of osteoporotic thoracolumbar fracture (OTLF), the complication of cement leakage has become an increasing concern. Although most cement leakage has no obvious clinical symptoms, some patients still sustain serious complications such as vertebral fracture, pulmonary embolism and spinal nerve compression. Cement leakage is closely related to patients′ own factors, cement factors and perioperative related factors. To clarify the risk factors of cement leakage with implementation of preventive measures accordingly is of great guiding significance to improve the clinical efficacy and surgical safety. Therefore, the authors discuss bone cement leakage in aspects of the risk factors and preventive measures so as to provide a reference for reducing the incidence of cement leakage.

ABSTRACT

Objective:To compare postural reduction combined with percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (OVCFs).Methods:From January 2019 to January 2020,68 patients with OVCFs who met the inclusion and exclusion criteria in the Second Hospital of Tangshan Hebei Province were included in the observation study. A prospective randomized controlled study was used. The matched groups were divided into PVP combined group (adjust the overextension of the operating table by 20°-30°, if the posture reduction fails, pry the puncture needle on both sides in reverse according to the compression degree of the end plate before operation, and inject bone cement) and PKP group (do not adjust the operating table before operation, insert a balloon and expand on both sides after operation, and inject bone cement), with 34 cases in each group. The Cobb angle of the injured vertebrae was measured by taking the anterior and lateral X-ray film of the patient's lumbar spine before operation. The degree of pain and low back function were evaluated by visual analogue scale (VAS) and Oswetry disability index (ODI). The operation time and fluoroscopy times were recorded during the operation. On the second day after operation, the anterior and lateral X-ray of lumbar spine were taken to measure the Cobb angle of injured vertebrae. All patients were underwent computed tomography (CT) check the bone cement for leakage, record the VAS score, and record the ODI 3 months after operation to evaluate the patient's function. Follow up at the end of 12 months after operation to count the treatment cost and re-fracture of the patient. The data analysis and measurement data were compared by independent sample t-test between the two groups, paired sample t-test was used for intra-group comparison before and after operation. χ 2 test was used for counting data comparison between two groups. Results:All patients were followed up for 12 months. The operation time ((42.7±5.9) min), fluoroscopy times ((20.0±3.6) times) and treatment cost ((19 153±601) yuan) in the PVP combined group were better than those in the PKP Group ((67.4±7.3) min, (30.1±5.9) times, (27 496±669) yuan), and the difference was statistically significant ( t values were 15.39, 8.46, 54.12; all P<0.001). Cobb angle: Postoperative Cobb angle of injured vertebrae in the two groups (PVP combined group (10.7±4.5)°) and (PKP group (13.4±3.8)°) decreased compared with preoperative (PVP combined group (17.0±5.1)°) and (PKP group (16.7±5.1)°) ( t values were 10.61, 5.61; all P=0.001), and PVP combined group recovered better than PKP group, with statistically significant difference ( t=2.70, P=0.009). VAS score: Postoperative (PVP combined group (3.9±1.5) points) and (PKP group (4.1±1.6) points) was lower than preoperative the scores of (PVP combined group (6.9±1.1) points) and (PKP group (7.1±0.9) points), and the difference was statistically significant ( t values were 8.63, 8.88; all P=0.001). There was no significant difference in VAS scores between the two groups ( t=0.48, P=0.630). ODI scores: The scores of (PVP combined group (0.315±0.068)) and (PKP group (0.319±0.077)) after operation were lower than preoperative (PVP combined group (0.574±0.066), (PKP group (0.553±0.075)), and the difference was statistically significant ( t values were 18.54, 14.16, all P=0.001). There was no significant difference in ODI between the two groups ( t=0.25, P=0.803). There was no statistical significance in the two groups of postoperative bone cement leakage (χ 2=0.22, P=0.642). In PVP combined group, 1 case was re-fractured due to trauma, and there was no re-fracture in PKP group. Conclusion:Postural reduction combined with percutaneous needle prying reduction of PVP and PKP can alleviate the pain, improve the postoperative function and restore kyphosis in patients with OVCFs. Postural reduction combined with needle prying reduction of PVP has more advantages in operation time, radiation injury to doctors and patients, treatment cost, and the effect of correcting deformity is more significant.

ABSTRACT

OBJECTIVE@#To investigate the effects of different bone cement morphology distribution on the clinical efficacy of unilateral percutaneous vertebroplasty(PVP) for spinal osteoporotic fractures.@*METHODS@#The clinical data of 66 patients with osteoporotic vertebral compression fractures received unilateral PVP treatment from January 2019 to April 2020 were retrospectively analyzed. There were 16 males and 50 females, including 83 vertebral bodies, 45 thoracic vertebrae and 38 lumbar vertebrae, and 55 patients with single-segment, 6 double-segment, 4 three-segment and 1 four-segment. The age ranged from 60 to 93 years with an average of (76.83±8.65) years. The included patients were admitted to hospital 1 to 10 days after onset, and were diagnosed by anteroposterior and lateral X-rays, MRI and bone density examination before surgery. According to the shape of bone cement in postoperative X-ray, the patients were divided into O-shaped group (28 cases) and H-shaped group (38 cases). In O-shaped group, the bone cement presented agglomeration mass distribution in the affected vertebra in postoperative X-ray while the bone cement presented disseminated honeycomb distribution in the affected vertebrae in H-shaped group. Bone cement injection volume was collected in two groups. The intraoperative bone cement leakage and postoperative adjacent vertebral fractures were observed. The VAS of the two groups before operation and 1 day, 1 month, 6 months and 1 year after operation were compared;and ODI of the two groups 1 day, 6 months and 1 year after operation were compared. The kyphosis angle and anterior height of the affected vertebrae were measured before operation and 1 week, 1 year after operation.@*RESULTS@#All 66 patients completed 1-year follow-up, and all patients healed well at the puncture site after surgery. There were 1 case and 8 cases of bone cement leakage in O-shaped group and H-shaped group during surgery respectively (P<0.05), but no serious complications occurred. One case occurred adjacent vertebral fracture in both groups during one-year follow-up (P>0.05). There was no statistical significance in injection amount of bone cement between the two groups (P>0.05). The VAS scores of O-shaped group and H-shaped group were 7.89±0.79, 2.75±1.08, 0.46±0.58, 0.36±0.49 and 8.00±1.04, 2.58±1.15, 0.53±0.56, 0.42±0.50 before operation, 1 day, 6 months, 1 year after operation respectively, and there was no statistical significance(P>0.05), and the VAS scores were 0.96±0.58 and 1.18±0.83 at 1 month after operation respectively, with statistical significance(P<0.05). The ODI scores of O-shaped group and H-shaped group were 12.43±3.78, 10.00±2.46, 8.43±1.50 and 12.11±3.68, 9.53±2.35, 8.32±1.51 at 1 day, 6 months and 1 year after surgery respectively, and there was no statistical significance between the two groups(P>0.05). There were no statistical significance in kyphotic angles and anterior height before surgery and 1 week, 1 year after surgery between two groups (P>0.05).@*CONCLUSION@#No matter the distribution of bone cement is O-shape or H-shape, it can achieve good clinical effect, and the prognosis effect is equivalent. Therefore, when performing unilateral puncture PVP surgery, it is not necessary to deliberately increase the puncture angle of the puncture needle in order to achieve the full diffusion of the affected vertebrae, so as to reduce the risk of damaging important structures and bone cement leakage.

ABSTRACT

OBJECTIVE@#To analyze the efficacy of percutaneous vertebroplasty for osteoporotic vertebral compression fractures with spinal origin abdominal pain as the main symptom.@*METHODS@#A retrospective analysis was performed on 37 patients with osteoporotic vertebral compression fractures treated from January 2015 to January 2021, all of whom had spin-derived abdominal pain as the main symptom, and were divided into surgery group(21 cases) and conservative group (16 cases) according to different treatment methods. Patients in the surgery group were treated with percutaneous vertebroplasty, including 7 males and 14 females, with an average age of (75.95±6.84) years old and an average course of disease of (5.26±3.79) days. The conservative group received non-surgical treatment, including 5 males and 11 females, with an average age of (75.50±8.07) years old and an average course of disease of (4.28±3.42) days. Two groups of patients with preoperative mainly characterized by abdominal pain, abdominal distension and constipation, have no obvious chest waist back pain symptoms, the thoracolumbar MRI diagnosed as fresh osteoporotic vertebral compression fractures, record its postoperative abdominal pain visual analogue scale (VAS), medical outcomes study short form-36 (SF-36) score, defecation interval after treatment, etc.@*RESULTS@#Thirty-seven patients were followed up for (14.90±14.11) months in surgery group and( 21.42±17.53) months in conservative group. Compared with before treatment, the VAS of surgery group at each time period after treatment, VAS of conservative group at 1 month after treatment and SF-36 score between two groups at 3 months after treatment were all improved(P<0.05), while VAS of conservative group at 3 days after treatment showed no statistically significant difference(P>0.05). Compared between two groups, there were no significant differences in VAS and SF-36 scores at 1 day before treatment(P>0.05), but VAS at 3 days after treatment in surgery group, life vitality and social function score at 3 months after treatment, and defecation time after treatment in surgery group were better than those in conservative group(P<0.05). There were no significant differences in other indexes(P>0.05). The incision healing of patients in surgery group was good, and no serious complications occurred in both groups.@*CONCLUSION@#Percutaneous vertebroplasty is an effective method for the treatment of osteoporotic vertebral compression fractures with spinal origin abdominal pain as the main symptom. Compared with conservative treatment, percutaneous vertebroplasty has more advantages in early relief of abdominal pain and constipation, recovery of vitality and social function.

ABSTRACT

ABSTRACT Objective: To evaluate the results of percutaneous vertebroplasty (PV) in spinal fragility fractures (osteoporosis/tumor), analyzing possible complications. Method: We evaluated 33 patients with spinal fractures (FXV) due to osteoporosis or tumor who underwent PV between January and November 2021. A physical examination was performed, obtaining the history and risk factors for bone fragility/tumor and a radiological evaluation of the spine to verify FXV. Genant's semiquantitative method was used for postoperative classification, the VAS score, and a disability questionnaire (ODI). A radiologist evaluated tomographic control to quantify vertebral filling and extravasation, determining where they occurred. Results: 46 vertebrae of 33 patients were operated on, with a mean age of 71 years, and 11 patients with more than one level of surgery. Of the total, 13 patients had tumor fractures, and 20 had fractures due to insufficiency. PMMA extravasation was observed in 31 vertebrae, most frequently in the External Vertebral Venous Plexus (23), Discal Body (9), Anterior Epidural Recess (4), Pulmonary Vessels (4), Internal Vertebral Venous Plexus (3), Inferior Cava (2), Adipose Plane (2) and Azygos Vein (1). No patient had clinical complications. Furthermore, the mean preoperative VAS was eight, the postoperative one was 3, the mean preoperative ODI was 56, and the postoperative one was 30. Conclusion: PMMA extravasation was frequent in several locations and levels without any clinical complications. VP proved to be effective in improving pain and function. Level III; Longitudinal Retrospective Cohort Study.

ABSTRACT

La osteoporosis es una enfermedad sistémica que deteriora la calidad del hueso y su arquitectura. Como consecuencia, predispone a fracturas por fragilidad, entre las cuales las fracturas vertebrales son frecuentes. Estas se asocian a una gran morbimortalidad. La vertebroplastia ha surgido en 1984 como alter-nativa terapéutica para tratar algunos tumores vertebrales y fracturas vertebrales osteoporóticas dolorosas. Este procedimiento consiste en la inyección de cemento guiado por imágenes, para estabilizar la vértebra fracturada y disminuir el dolor. La vertebroplastia puede ser realizada con anestesia local, sedación o anestesia general. La fuga de cemento fuera de la vértebra es una complicación común; sin embargo esto no suele tener traducción clínica y solamente se trata de un hallazgo imagenológico. En este artículo revisaremos las indicaciones, contraindicaciones, la eficacia, controversias y las complicaciones de la vertebroplastia percutánea. (AU)


Osteoporosis is a systemic disease characterized by bone quality deterioration. As a consequence of this deterioration, osteoporosis results in high fracture risk due to bone fragility. Fractures to the spine are common in this scenario, and relate to an increased morbi-mortality. Vertebroplasty emerged in 1984 as an alternative to treat painful vertebral tumors and osteoporotic vertebral fractures. This procedure relies on image guided cement injection to achieve pain relief and strengthen the vertebral body. Vertebroplasty can be performed under local anesthesia, mild sedation, or general anesthesia. Among its complications, cement leakage is common but it is rarely associated with any symptoms and it is usually an imaging finding. In this article, we will review indications and contraindications, effectiveness, controversies and complications related to percutaneous vertebroplasty. (AU)

ABSTRACT

ABSTRACT Introduction: Vertebral fracture is the main complication of osteoporosis and is common among the elderly. Conservative treatment is the first choice for osteoporotic vertebral compression fractures (OVCF) but for persistent painful cases, percutaneous vertebral cement augmentation techniques, such as vertebroplasty and kyphoplasty, are indicated. We performed a systematic review to compare clinical and radiological outcomes of both methods. Methods: A systematic review was performed according to the PRISMA and Cochrane Handbook for Systematic Reviews of Interventions. The PICO search strategy consisted of the following terms: Population- Patients with OVCFs; Intervention- Kyphoplasty; Control- Vertebroplasty; Outcomes- Pain, Cement Leakage, Vertebral Body Height, Adjacent level fractures, Oswestry (ODI) and SF36. Results: Seven articles were included in the qualitative analysis, selecting only randomized controlled trials. Four hundred and fifty patients were treated with vertebroplasty (VP) and 469 with kyphoplasty (KP). The leakage rate of the VP group was 63% versus 14% for the KP group. However, these results were without statistical significance. The Visual Analogue Scale (VAS), ODI and SF-36 outcomes were evaluated based on the 6-month and 1-year follow-up results, and we were unable to find any significant differences between treatments. For restoration of vertebral height, the values of the KP group were, on average, 0.71 cm higher than those of the VP group, with 95% CI. Conclusion: Based on this systematic review, kyphoplasty is superior to vertebroplasty for achieving gains in vertebral body height. As regards cement leakage and other clinical outcomes, neither method showed statistically significant superiority. Level of Evidence I; Systematic review.


RESUMO Introdução: A fratura vertebral é a principal complicação da osteoporose e ocorre com frequência em idosos. O tratamento conservador é a primeira escolha para fraturas compressivas vertebrais por osteoporose (FCVO), mas para casos dolorosos persistentes, as técnicas de cimentação vertebral, como vertebroplastia e cifoplastia, são indicadas. Realizamos uma revisão sistemática para comparar os resultados clínicos e radiológicos de ambos os métodos. Métodos: Uma revisão sistemática foi realizada de acordo com o PRISMA e o Manual Cochrane de Revisões Sistemáticas. A estratégia de busca PICO foi: População - Pacientes com FCVOs; Intervenção - Cifoplastia; Controle - Vertebroplastia; Resultados - Dor, Extravazamento de Cimento, Altura do Corpo Vertebral, Fraturas em Nível Adjacente, Oswestry (ODI) e SF36. Resultados: Sete artigos foram incluídos na análise qualitativa, somente ensaios clínicos randomizados. Quatrocentos e cinquenta pacientes foram tratados com vertebroplastia (VP) e 469 com cifoplastia (CP). A taxa de extravazamento de cimento do grupo VP foi de 63% contra 14% do CP, no entanto, não atingiu significância estatística. Os desfechos da Escala Visual Analógica (EVA), ODI e SF-36 foram avaliados considerando os resultados de seis meses e um ano de seguimento e não pudemos apontar diferenças entre os tratamentos. Por fim, a CP apresenta valores médios 0,71 cm maiores do que a VP para a restauração da altura do corpo vertebral, com IC de 95%. Conclusão: Nesta revisão sistemática a cifoplastia foi superior à vertebroplastia para ganho de altura do corpo vertebral. Não houve superioridade estatisticamente significativa entre os dois métodos para extravazamento de cimento e outros resultados clínicos. Nível de Evidência I; Revisão sistemática

ABSTRACT

ABSTRACT Kyphoplasty (KP) and vertebroplasty (VP) are both widely adopted treatments for patients with osteoporotic vertebral fractures (OVF), however, which of these techniques is more effective has not yet been established. We performed a systematic review of articles, followed by meta-analysis, in an attempt to establish the differences between KP and VP. Initially, 187 articles were obtained, 20 of which were systematically reviewed and submitted to meta-analysis. Thus, 2,226 patients comprised the universe of the present article, 1202 of whom underwent KP and 1024 of whom underwent VP. The statistically significant results observed included lower mean bone cement leakage (ml) in the group submitted to kyphoplasty, with OR: 1.50 [CI95%: 1.16 - 1.95], p <0.05; shorter mean surgical time (minutes), 0.45 [CI90% 0.08 - 0.82], p <0.1, for the group submitted to VP as compared to the KP group; and a lower mean postoperative Oswestry Disability Index score in the KP group, OR: −0.14 [CI95%: −0.28 - 0.01], p <0.05. KP was more effective in improving physical function and had a lower frequency of cement leakage when compared to VP, although it requires longer surgical time. Level of evidence III; Systematic review of level III studies.


RESUMO Tanto a cifoplastia (KP) quanto a vertebroplastia (VP) são tratamentos bastante adotados para pacientes com fratura vertebral osteoporótica (FVO), no entanto, ainda não foi estabelecido qual destas é a técnica de maior eficácia. Realizamos uma revisão sistemática de artigos, seguida de metanálise, na tentativa de estabelecer as diferenças entre KP e VP. Foram obtidos inicialmente 187 artigos, sendo que destes, 20 foram revisados sistematicamente e submetidos à metanálise. Assim, 2226 pacientes compuseram o universo do presente artigo, sendo 1202 destes submetidos à KP e 1024 à VP. Entre os resultados estatisticamente significativos, foi observado um menor extravasamento médio de cimento ósseo (ml) no grupo submetido à cifoplastia, OR: 1,50 [IC 95%: 1,16 - 1,95], p < 0,05; o tempo médio de operação (minutos) 0,45 [IC 90%: 0,08 - 0,82], p < 0,1, na comparação entre KP e VP é menor no grupo submetido à vertebroplastia e no pós-cirúrgico, o Índice Médio de Incapacidade de Oswestry foi menor no grupo KP OR: −0,14 [IC 95% −0,28 - 0,01], p < 0,05. A KP foi mais eficaz na melhora da função física e menor frequência de extravasamento de cimento quando comparada à VP embora demande maior tempo cirúrgico. Nível de evidência III; Revisão sistemática de estudos de nível III.

ABSTRACT

Objective:To investigate the clinical effectiveness of vertebroplasty for osteoporotic vertebral compression fractures in the elderly aged 90 years and over.Methods:Clinical data of 64 elderly patients aged 90 years and over who had undergone percutaneous vertebroplasty for vertebral compression fractures between January 2015 and January 2021 were retrospectively analyzed.Changes in preoperative and postoperative pain, intraoperative bone cement leakage, postoperative pneumonia, bedsores, urinary tract infections, lower extremity venous thrombosis and changes in preoperative and postoperative physical mobility were evaluated.Pain scores, physical mobility scores, bone cement extravasation and complications such as re-fractures of the vertebral body, postoperative pneumonia, bedsores, urinary tract infections and thrombosis were recorded before surgery, 3 and 30 days after surgery.Results:The visual analogue scale(VAS)scores of 64 patients before surgery, 3 and 30 days after the procedure were 8.34±1.12, 2.17±1.45 and 1.83±1.15, retrospectively( F=540.876, P<0.01). The physical mobility scores before surgery, 3 and 30 days after the procedure were 2.83±0.94, 1.59±0.70 and 1.39±0.60, retrospectively( F=65.492, P<0.01). There were 18 cases(28.13%)of bone cement leakage during surgery, 4 cases(6.25%)of pneumonia within 30 days after surgery, 9 cases(14.06%)of urinary tract infections, 3 cases(4.69%)of lower extremity venous thrombosis, 1 case(1.56%)of bedsores, and 2 cases(3.13%)of vertebral re-fractures after surgery.No patient died during the 30-day follow-up. Conclusions:Percutaneous vertebroplasty can reduce pain and improve physical mobility and is an effective and safe minimally invasive treatment for elderly patients with spinal compression fractures aged 90 years and over.

ABSTRACT

Thoracolumbar osteoporotic vertebral compression fracture(OVCF)is more common in patients with osteoporosis,which seriously affects the life quality of the elderly. Percutaneous vertebroplasty(PVP)and percutaneous kyphoplasty(PKP)are the conventionally effective strategies for treatment of OVCF,whereas quite a lot OVCF patients still sufferred from residual back pain,affecting postoperative recovery. Bone density,postoperative infection,cement leakage induced nerve injury,fascia injury and facet joint violation may be the potential factors for residual back pain. In this study,the authors review advances in the definition of residual back pain in OVCF after surgery and related risk factors including injured vertebrae,bone density,fascia injury,intravertebral vacuum cleft,cement volume and distribution,surgical related factors including facet joint violation,hoping to provide a reference for clinical treatment.

ABSTRACT

Objective:To compare the clinical efficacy of percutaneous vertebroplasty (PVP) and non-surgical treatment of patients with type I fracture according to the acute symptomatic osteoporotic thoracolumbar fracture (ASOTLF) classification.Methods:A retrospective case-control study was used to analyze the clinical data of 115 patients with ASOTLF admitted to Honghui Hospital of Xi'an Jiaotong University from January 2015 to December 2018. There were 48 males and 67 females, aged 65-92 years [(75.3±8.5)years]. According to clinical symptoms and imaging characteristics, all patients were identified with type I fracture according to the ASOTLF classification. Injury segments were at T 6 to T 10 in 10 patients, at T 11 in 15, at T 12 in 26, at L 1 in 34, ay L 2 in 18, at L 3 in 7, and at L 4 in 5. A total of 73 patients received PVP combined with anti-osteoporosis treatment (surgery group), and 42 patients received non-surgery combined anti-osteoporosis treatment (non-surgery group). Before treatment, at 1 day, 1 month, 3 months, 6 months after treatment, and at the last follow-up, the visual analogue scale (VAS) was used to assess the pain, the Roland Morris Disability (RMD) score to assess the spinal function, and the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) score to evaluate the quality of life. The bone mineral density was compared between groups before treatment and at 1 year after treatment. The complications were observed as well. Results:All patients were followed up for 12-18 months [(13.2±4.6)months]. At 1 day, 1 month, and 3 months after treatment, the VAS in surgery group [(3.9±0.6)points, (3.3±0.6)points, (2.9±0.3)points] was significantly lower than that in non-surgery group [(6.0±0.7)points, (5.0±0.8)points, (4.2±1.0)points, respectively] (all P<0.05); the RMD score in surgery group [(15.2±0.7)points, (12.6±0.7)points, (10.6±0.7)points] was significantly lower than that in non-surgery group [(16.4±0.8)points, (14.6±0.8)points, (12.7±0.6)points, respectively] (all P<0.05). At 1 day and 1 month after treatment, the QUALEFFO score in surgery group [(46.0±1.1)points, (41.4±0.8)points] was lower than that in non-surgery group [(50.3±0.8)points, (44.7±1.2)points] (all P<0.05). There was no statistically significant difference between the two groups at other time points of the above indicators ( P>0.05). At 1 year after treatment, the bone mineral density in surgery group was (-3.0±0.9)SD, and was (-2.8±1.1)SD in non-surgery group ( P>0.05). There was no significant difference in the incidence of complications between surgery group [37%(27/73)] and non-surgery group [33%(14/42)] ( P>0.05). Conclusion:For patients with ASOTLF type I fracture, PVP and non-surgical treatment has similar effects in anti-osteoporosis and occurrence of complications, but the PVP is superior to non-surgical treatment in early pain relief, spinal function improvement and quality of life.

ABSTRACT

Objective:To explore different surgical treatment options and effect for intraspinal cement leakage after percutaneous vertebroplasty (PVP).Methods:A retrospective case series study was carried out to analyze the clinical data of 5 patients with intraspinal cement leakage after PVP for osteoporotic vertebral compression fracture (OVCF) admitted to People's Hospital of Shanxi between May 2016 and January 2020, including 1 male and 4 females, with the age of 65-82 years [(75.4±7.5)years]. Injured segments were located at T 12-L 1 in 1 patient, L 1 in 1, L 2-4 in 1, L 3 in 1 and L 4-5 in 1. The American Spinal Injury Association (ASIA) classification was grade C in 2 patients and grade D in 3. Muscle strength was grade II in 2 patients and grade III in 3. The leakage of bone cement in the spinal canal was strip or columnar in 3 patients, leaning to one side of the spinal canal and adjacent to the nerve root, and the bone cement was removed by transforaminal endoscope for decompression. The leakage of bone cement in the dura mater and spinal canal was found in 2 patients. The intradural bone cement leakage was removed by durotomy, and the bone cement in the spinal canal was removed by transpedicular osteotomy, bone graft fusion and internal fixation. The visual analogue scale (VAS), Oswestry dysfunction index (ODI), ASIA grade and muscle strength were observed before operation, at 3 days, 3 months after operation and at the last follow-up. Results:All patients were followed up for 12-16 months [(13.6±1.8)months]. The VAS was significantly decreased at postoperative 3 days, 3 months and at the last follow-up [(2.6±0.6)points, (2.1±0.3)points, (1.9±0.5)points] when compared to (7.1±1.5)points before operation ( P<0.01). However, the VAS had no statistical difference at different time points after operation ( P>0.05). The ODI was 42.4±10.2, 25.6±6.0 and 21.4±3.6 at postoperative 3 days, 3 months and at the last follow-up, significantly different from that before operation (74.2±7.3) ( P<0.05 or 0.01). However, the ODI had no statistical difference at postoperative 3 months and at the last follow-up ( P>0.05). Two patients with preoperative ASIA grade C recovered to grade D and 3 patients with preoperative grade D recovered to grade E at the last follow-up ( P<0.05). Two patients could walk without crutches with muscle strength improved from grade II preoperatively to grade IV at the last follow-up ( P<0.01). Three patients had completed recovery of neurological function with muscle strength improved from grade III preoperatively to grade V at the last follow-up ( P<0.01). Conclusions:For OVCF patients with intraspinal canal cement leakage and neurological symptoms after PVP, if the bone cement is located on one side of the spinal canal and adjacent to the nerve root, the bone cement should be removed by foraminal endoscope for decompression; if the cement leakage occurs in the dura mater, the dura mater should be cut to remove the bone cement for decompression, which can effectively relieve pain and promote functional recovery.

ABSTRACT

Objective:To evaluate the clinical outcomes of short-segmental fixation combined with vertebroplasty via bone cement-augmented screws in treating old osteoporotic thoracolumbar vertebral fracture nonunion (OOVFN) accompanied by spinal cord injury.Methods:A retrospective case series study was made on 32 patients with OOVFN accompanied by spinal cord injury admitted to Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology between October 2012 and November 2019, including 10 males and 22 females. The age ranged from 50 to 76 years [(62.4±8.0)years]. Level of injury was T 11 in patients, T 12 in 7, L 1 in 7, L 2 in 6, L 3 in 5, L 4 in 3. Frankel classification for spinal nerve injury was grade B in 7 patients, grade C in 13 and grade D in 12. All underwent short-segmental fixation combined with vertebroplasty via bone cement-augmented screws. The operation time, intraoperative blood loss, and volume of bone cement injected in the fracture vertebra were documented. The anterior and posterior vertebral height, Cobb angle for local kyphosis and spinal canal volume at the fracture level were measured to evaluate the reduction, and the visual analog scale (VAS), Oswestry disability index (ODI) and Frankel classification were used to evaluate clinical outcomes pre-, post-operatively and at the last follow-up. The post-operative complications were recorded. Results:All patients completed the follow-up, with the follow-up duration of 12-85 months [(44.8±17.5)months]. The operation time was 90-135 minutes[(109.5±14.1)minutes] and intraoperative blood loss was 80-220 ml[(157.2±38.5)ml]. The volume of bone cement injected in the fracture vertebra was 3.5-6.5 ml[(5.0±1.1)ml]. The anterior vertebral height was restored from (9.8±2.2)mm preoperatively to (19.8±2.7)mm at one week postoperatively and to (19.7±2.5)mm at the last follow-up ( P<0.01). The Cobb angle was corrected from (21.8±4.7)° preoperatively to (5.4±2.7)° at one week postoperatively and to (5.5±2.7)°at the last follow-up ( P<0.01). The cross-sectional area of spinal canal was enlarged from (595.8±102.3)mm 2 preoperatively to (1, 093.6±144.9)mm 2 at one week postoperatively and to (1, 103.9±147.9)mm 2 at the last follow-up ( P<0.01). The posterior vertebral height was maintained during the perioperative period ( P>0.05). The VAS and NDI decreased from (7.7±1.3)points and 79.1±14.7 preoperatively to (2.5±0.8)points, 31.8±9.8 at one week postoperatively and to (2.3±0.6)points and 31.8±9.8 at the final follow-up ( P<0.01). The spinal nerve injury showed improvement at the final follow-up, with Frankel grade B in 1 patients, grade C in 6, grade D in 15 and grade E in 10 ( P<0.01). Two patients with bone cement leakage into spinal canal were observed intraoperatively, which was cleared during decompression. Five patients with local bone cement leakage and no leakage into spinal canal were recorded during the follow-up. There was no neurological symptom deterioration, wound infection or internal fixation loosening or failure during the follow-up. Conclusion:For patients with OOVFN accompanied by spinal cord injury, short-segmental fixation combined with vertebroplasty via bone cement-augmented screws can restore and maintain vertebral alignment, relieve pain and promote neurological function recovery.

ABSTRACT

Objective:To evaluate the efficacy of unilateral puncture techniques in high-viscosity cement percutanueous vertebroplasty (PVP) in treatment of type I chronic symptomatic osteoporotic vertebral compression fracture (CSOVCF).Methods:A retrospective case control study was conducted to analyze the clinical data of 119 patients with type I CSOVCF admitted to Honghui Hospital affiliated to Xi'an Jiaotong University School of Medicine from December 2013 to December 2016. There were 42 males and 77 females, aged 58-95 years [(79.2±15.6)years]. All patients had bone mineral density of -4.5--2.5 SD [(-3.9±0.2)SD] (T score). The fractured segments included L 1-L 2 in 56 patients and L 3-L 5 in 63. All patients were treated by high-viscosity cement PVP with the unilateral puncture of transverse process and superior articular process in unilateral group ( n=60) and by the bilateral puncture approach with the Magerl method in bilaleral group ( n=59). The operation time, cement injection volume, and intraoperative fluoroscopy frequency were recorded. The visual analogue scale (VAS), Oswestry dysfunction index (ODI), anterior height ratio of injured vertebrae and Cobb angle were measured before operation, at postoperative 1 day and at the last follow-up. The adjacent vertebral fracture, cement leakage and other complications were recorded. Results:All patients were followed up for 12-48 months [(24.1±5.6)months]. The operation time in unilateral group [(21.5±6.5)minutes] was significantly shorter than that in bilateral group [(37.8±7.4)minutes] ( P<0.05). The cement injection volume in unilateral group [(4.2±0.7)ml] was less than that in bilateral group [(6.5±1.1)ml]( P<0.05). The intraoperative fluoroscopy frequency in unilateral group [(14.2±3.0)times] was less than that in bilateral group [(31.4±6.4)times] ( P<0.05). Both groups showed significant improvements in VAS, ODI, anterior height ratio of injured vertebrae and Cobb angle at postoperative 1 day and at the last follow-up compared with these before operation ( P<0.05), but there were no significant differences after operation between the two groups ( P>0.05). The incidence of adjacent vertebral fracture was 5%(3/60) in unilateral group and 8% (5/59) in bilaleral group ( P>0.05). Four patients (7%) had cement leakage in unilateral group and 11 patients (19%) in bilateral group ( P<0.05). No complications of wound infection, nerve injury or pulmonary embolism occurred. Conclusion:Compared with Magerl bilateral puncture approach, high-viscosity cement PVP with unilateral puncture of transverse process and superior articular process in treatment of type I CSOVCF has advantages of shorter operation time, less trauma, less radiation exposure and lower cement leakage rate.

ABSTRACT

Objective:To explore the clinical effect of percutaneous vertebroplasty (PVP) at stage I in treatment of acute multi-segment osteoporotic vertebral compression fracture (OVCF) in the elderly with over 3 vertebrae operated.Methods:A retrospective case-control study was conducted to analyze the clinical data of 105 aged patients with acute multi-segment OVCF admitted to Honghui Hospital, Xi'an Jiaotong University from October 2015 to February 2019. There were 27 males and 78 females, aged 65-92 years [(73.0±14.5)years]. All patients received stage I multi-segmental PVP and standard anti-osteoporosis treatment. There were more than 3 operative vertebral segments in 30 patients (observation group) and less than or equal to 3 operative vertebral segments in 75 patients (control group). The operation time, intraoperative fluoroscopy frequency, cement injection volume, cement leakage rate and incidence of recurrent vertebral fractures were compared between the two groups. The visual analogue scale (VAS), Oswestry disability index (ODI) and activity of daily living (ADL) score were compared before operation, 1 day, 1 month after operation and at the last follow-up.Results:All patients were followed up for 11-13 months [(12.5±1.8)months]. The observation group showed operation time of (71.2±12.2)minutes, intraoperative fluoroscopy frequency of (38.8±6.4)times and cement injection volume of (20.2±4.6)ml, more than those in control group [(52.3±10.6)minutes, (25.4±5.3)times, (12.3±4.3)ml] ( P<0.05). There was no significant difference in cement leakage rate and incidence of recurrent vertebral fractures between the two groups ( P>0.05). No complications such as infection, nerve damage or cement implantation syndrome occurred. Before operation, 1 day after operation, 1 month after operation and at the last follow-up, the VAS in observation group [(7.6±0.7)points, (3.0±0.8)points, (2.3±0.7)points, (2.2±0.6)points] showed no significant difference from those in control group [(7.4±0.5)points, (2.9±0.4)points, (2.1±0.5)points, (2.0±0.5)points], the ODI in observation group [(74.6±3.3)%, (36.8±4.6)%, (29.7±4.0)%, (24.0±3.6)%] did not differ from those in control group [(73.8±1.0)%, (35.1±0.9)%, (28.4±2.2)%, (22.8±0.9)%], the ADL score in observation group [(34.5±5.0)points, (54.5±3.8)points, (73.7±3.9)points] were similar with those in control group [(36.2±3.4)points, (56.8±4.7)points, (75.3±5.3)points, (81.3±4.5)points] (all P>0.05). The postoperative VAS, ODI and ADL score in both groups were significantly improved in comparison with preoperation ( P<0.05). Conclusion:For acute multi-segment OVCF in the elderly with over 3 or not more than 3 the vertebrae operated, PVP at stage I has the same advantages in early pain relief and improvement of motor function and quality of life.
