ABSTRACT
Objective To study the curative effects of traditional Chinese medicine paste combined with Baduanjin in treatment of osteoporotic vertebral compression fracture (OVCF) after percutaneous vertebroplasty (PVP). Methods 120 OVCF patients treated with PVP in our hospital from January 2016 to September 2017 were divided into the observation group (60 cases) and the control group (60 cases) according to the random number table method. The control group was given calcium carbonate D3 chewable tablets orally with routine guidance. In addition to the same treatment as the control group, the observation group received the traditional Chinese medicine paste orally with Baduanjin exercise. Both groups were treated for 6 months and followed-up for 3 years. The curative effects in the two groups after 6 months treatment and the low back pain after 1, 3 and 6 months of treatment were recorded. The changes of bone mineral density (BMD), kyphosis angle (Cobb angle), anterior wall height of vertebral body (AVBH) and level of bone metabolism indexes in the two groups were compared before and after treatment for 6 months. The follow-up times and the incidences of push-back fracture after PVP during follow-up were recorded. Results After 6 months of treatment, the clinical cure rate of the observation group was 73.33%, which was higher than 53.33% of the control group(P<0.05). Compared with pretreatment, the scores of visual analogue scale (VAS) in the two groups gradually decreased after 3 and 6 months of treatment, and the observation group had a lower scores than the control group (P<0.05). After 6 months treatment, BMD and AVBH of lumbar vertebrae and femoral neck in both groups increased, and the observation group was higher than that in the control group. The Cobb angle and serum levels of Type I procollagen degradation products (β-Cross I), the n-terminal middle osteocalcin (N-MID Ost) and parathyroid hormone (PTH) decreased in both groups, and the observation group was lower than those in the control group (P<0.05). There was no significant difference in fracture incidence after PVP in the year 1, year 1 to 3 follow up between the two groups (P>0.05). During the 3 years follow-up, the incidence of push-body fracture after PVP in the observation group was 3.33%, which was lower than that in the control group 20.00%( P<0.05). Conclusion Traditional Chinese medicine paste combined with Baduanjin reduced the serum levels of β-Cross I, N-MID Ost and PTH, regulated bone metabolism, improved BMD and AVBH of lumbar vertebrae and femoral neck, reduced Cobb angle, promoted the recovery of lumbar function, alleviated patients' back pain, lowered the incidence of push-body fracture after PVP. The curative effects were remarkable.
ABSTRACT
Objective:To investigate the effect of self-made Bushen Jiangu Decoction on bone transformation markers in elderly patients with osteoporotic vertebral compression fracture after operation, and to evaluate the clinical efficacy.Methods:Prospective cohort study. A total of 92 patients with osteoporotic vertebral compression fracture after operation in Fangshan Hospital of Beijing University of Chinese Medicine from April 2020 to December 2021 who met the inclusion criteria were divided into 2 groups by random drawing method, with 46 in each group. The control group was treated with routine western medicine after operation, and the observation group was treated with self-made Bushen Jiangu Decoction on the basis of the control group. Both groups were treated for 3 months. TCM symptom scores were performed before and after treatment, and the prognosis of the patients was evaluated with the Chinese Osteoporosis Quality of Life (COQOL), VAS scale, and the Oswestry Dysfunction Index (ODI). The levels of amino terminal propeptide (PINP), cross-linked terminal peptide β special sequence (β-CTX) and bone morphogenetic protein 6 (BMP6) of type Ⅰ procollagen were determined by contrast chromogenic method with o-benzaldehyde. The adverse reactions during treatment were recorded and the clinical efficacy was evaluated.Results:The total effective rate was 95.7% (44/46) in the observation group and 82.6% (38/46) in the control group, and there was a significant difference between the two groups ( χ 2=4.04 , P=0.044). After treatment, the scores of fracture nonunion, pain in back and loin, chilliness and lassitude, and pallor in the observation group were significantly lower than those in the control group ( t values were 4.84, 4.09, 4.87, 4.14, respectively, P<0.01). The scores of COQOL, VAS and ODI in the observation group were significantly lower than those in the control group ( t values were 6.26, 10.57 and 6.15, respectively, P<0.01). The levels of PINP [(44.93±5.86)μg/L vs. (49.76±6.02)μg/L, t=3.90] and β-CTX [(0.49±0.17) μg/L vs. (0.68±0.20) μg/L, t=4.91] in observation group were significantly lower than those in the control group after treatment ( P<0.05). The level of BMP6 [(81.23±9.14) μg/L vs. (75.14±8.25) μg/L, t=3.36] in observation group was significantly higher than that of the control group ( P<0.05). During the treatment,the incidence of adverse reactions in the observation group was 13.0% (6/46), while that in the control group was 8.7% (4/46), and there was no significant difference between the two groups ( χ 2=0.45, P=0.503). Conclusion:The self-made Bushen Jiangu Decoction combined with conventional western medicine therapy can adjust the level of bone transformation markers in elderly patients with osteoporotic vertebral compression fractures, improve the lumbar function and quality of life, and improve the clinical efficacy.
ABSTRACT
OBJECTIVE@#To analyze the correlation between bone cement cortical leakage and injury degree of osteoporotic vertebral compression fracture (OVCF) after percutaneous kyphoplasty (PKP), and to provide guidance for reducing clinical complications.@*METHODS@#A clinical data of 125 patients with OVCF who received PKP between November 2019 and December 2021 and met the selection criteria was selected and analyzed. There were 20 males and 105 females. The median age was 72 years (range, 55-96 years). There were 108 single-segment fractures, 16 two-segment fractures, and 1 three-segment fracture. The disease duration ranged from 1 to 20 days (mean, 7.2 days). The amount of bone cement injected during operation was 2.5-8.0 mL, with an average of 6.04 mL. Based on the preoperative CT images, the standard S/H ratio of the injured vertebra was measured (S: the standard maximum rectangular area of the cross-section of the injured vertebral body, H: the standard minimum height of the sagittal position of the injured vertebral body). Based on postoperative X-ray films and CT images, the occurrence of bone cement leakage after operation and the cortical rupture at the cortical leakage site before operation were recorded. The correlation between the standard S/H ratio of the injured vertebra and the number of cortical leakage was analyzed.@*RESULTS@#Vascular leakage occurred in 67 patients at 123 sites of injured vertebrae, and cortical leakage in 97 patients at 299 sites. Preoperative CT image analysis showed that there were 287 sites (95.99%, 287/299) of cortical leakage had cortical rupture before operation. Thirteen patients were excluded because of vertebral compression of adjacent vertebrae. The standard S/H ratio of 112 injured vertebrae was 1.12-3.17 (mean, 1.67), of which 87 cases (268 sites) had cortical leakage. The Spearman correlation analysis showed a positive correlation between the number of cortical leakage of injured vertebra and the standard S/H ratio of injured vertebra ( r=0.493, P<0.001).@*CONCLUSION@#The incidence of cortical leakage of bone cement after PKP in OVCF patients is high, and cortical rupture is the basis of cortical leakage. The more severe the vertebral injury, the greater the probability of cortical leakage.

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 summarize the perioperative nursing points of percutaneous kyphoplasty (PKP) in elderly patients with osteoporotic vertebral compression fractures assisted by robots, so as to provide reference for orthopedic nursing.Methods:From July 2019 to February 2021, the data of 72 patients undergoing robot-assisted PKP in the spinal surgery of the First Affiliated Hospital of Anhui Medical University were retrospectively analyzed. The perioperative nursing points were summarized, and the nursing experience was summarized. The nursing under the new measures of precise minimally invasive treatment was analyzed and discussed. The length of hospital stay, postoperative ambulation time, complications and satisfaction survey results of patients were collected and recorded. The Numerical Rating Scale(NRS) score, Self-rating Anxiety Scale(SAS) score and Oswestry Disability Index (ODI) score before and after surgery were compared. The correlation analysis of the scores of various factors was combined to comprehensively evaluate the surgical and nursing effects.Results:All patients had no complications related to machine use during and after operation, and their symptoms were improved to varying degrees. Fifty-seven cases of indwelling catheter, catheter time (19.00±14.24) h. The preoperative hospitalization time was (6.16±2.22) d, and the postoperative hospitalization time was (1.94±0.99) d. Postoperative bed time was (16.34±6.81) h. Postoperative nursing satisfaction was (98.55±2.44)%.The postoperative NRS and SAS scores were (1.00±0.55) and (32.06±5.33) points, respectively, which were lower than those before operation (3.51 ± 0.71) and (39.08±8.86) points, and the differences were statistically significant ( t values were 33.976, 8.184, P<0.01). There were statistically significant differences in six indicators of ODI scores before and after surgery, including low back pain, walking, standing, sitting, sleep and self-care ( P<0.01). Correlation analysis showed that there was a strong correlation between the six ODI score factors and the NRS score. The four factors of sitting, walking, low back pain and standing were highly correlated with SAS. Conclusions:The implementation of good perioperative nursing management for patients with PKP assisted by robot can effectively promote the rehabilitation of patients, reduce the incidence of complications and improve patient satisfaction.

ABSTRACT
BACKGROUND: Percutaneous vertebral body stenting system (VBS) can alleviate patient's pain, recover the height of vertebral body, and correct local kyphosis, but there is no definite clinical study to show that It has obvious advantages over percutaneous kyphoplasty (PKP). OBJECTIVE: To compare the short-term effect of VBS versus PKP in the treatment of osteoporotic vertebral compression fracture. METHODS: Forty patients with osteoporotic vertebral compression fracture who received VBS or PKP between January 2017 and December 2018 In the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine were included in this study. They were divided into a VBS group (n=15) and a PKP group (n=25) according to surgery method. According to whether fluoroscopic operation was performed in retroextension position, two subgroups were designated: VBS retroextension group (n=7) and PKP retroextension group (n=14). RESULTS AND CONCLUSION: Compared with the PKP group, the amount of bone cement injected Into the vertebra was greater in the VBS group (P 0.05). Compared with preoperative situations, Visual Analogue Scale score was significantly decreased after surgery In both VBS and PKP groups, and further decreased at the last follow-up (P 0.05). These results suggest that VBS and PKP are effective in the treatment of osteoporotic vertebral compression fractures. VBS can better correct compression kyphosis deformity when more bone cement Is injected. The difference of therapeutic efficacy between two surgical approaches can be reduced with proper surgical position, keeping the surgical segment In the retroextension position.
ABSTRACT
OBJECTIVE: It remains disputed whether percutaneous curved vertebroplasty and unilateral pedicle approach percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fracture. This study systematically analyzed the efficacy and safety of percutaneous curved vertebroplasty and unilateral pedicle approach percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fracture. METHODS: A computer-based online search of Wanfang, VIP, CNKI, PubMed, EMBASE, The Cochrane library, and CBM was performed to retrieve randomized controlled trial studies regarding percutaneous curved vertebroplasty and unilateral pedicle approach percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fracture published before January 2020. Related papers were manually searched. After two evaluators independently selected literature, data were extracted and the quality of methodology included in the study was evaluated. Meta-analysis was carried out by using Stata/SE 12.0 software. RESULTS: (1) A total of eight randomized controlled trials were conducted, including 628 patients, of whom 394 were treated with percutaneous curved vertebroplasty and 404 with unilateral pedicle approach percutaneous vertebroplasty. (2) The meta-analysis results showed that visual analogue scale score [MD=-0.20, 95%CI(-0.28,-0.12), P < 0.05], the leakage rate of bone cement [RR=0.30, 95%CI(0.15, 0.58), P < 0.05], and the total distribution rate of bone cement in the center of vertebral body [RR=1.27, 95%CI(1.12, 1.45), P < 0.05] were better in the percutaneous curved vertebroplasty group than those in the unilateral pedicle approach percutaneous vertebroplasty group. (3) There was no significant difference in Oswestry disability index score [MD=-4.83, 95%CI (-9.71, 0.05), P=0.052], operation time [MD=-1.45, 95%CI(-5.91, 2.82), P=0.488]and X-ray exposure times [MD=-0.70, 95%CI(-2.11, 0.71), P=0.33] between the two methods. CONCLUSION: Percutaneous curved vertebroplasty exhibits significant advantages in analgesic effect, low leakage rate of bone cement and the high total distribution rate of bone cement in the center over unilateral pedicle approach percutaneous vertebroplasty. Therefore, a large number of high-quality multicenter randomized controlled trials are needed to provide more evidence.
ABSTRACT
BACKGROUND: Percutaneous curved vertebroplasty is a new method for the treatment of osteoporotic vertebral compression fractures, which can achieve a good therapeutic effect, while the distribution of bone cement has not been explored thoroughly. OBJECTIVE: To retrospectively analyze the therapeutic effect of percutaneous curved vertebroplasty and the distribution characteristics of bone cement in the treatment of osteoporotic vertebral compression fractures. METHODS: A total of 28 patients with osteoporotic vertebral compression fractures of a single thoracic or lumbar vertebrate, who were admitted to Qingdao Municipal Hospital from June 2017 to February 2018, including 2 males and 26 females, aged 62-86 years old, underwent percutaneous curved vertebroplasty and were retrospectively reviewed. The bone cement was injected at the puncture side, the middle of the vertebrate and the contralateral side respectively. The change of anterior vertebral body height of the injured vertebrae and the leakage of bone cement postoperatively were observed according to X-ray images preoperatively, 48 hours and 6 months postoperatively. The bone cement distribution within the vertebrate was observed by CT scanning. Visual analogue scale score and Oswestry disability index were recorded for the evaluation of recovery. All protocols were approved by the Ethical Committee of Qingdao Municipal Hospital. RESULTS AND CONCLUSION: (1) There were 6 out of 28 cases of bone cement leakage, including 4 cases of paravertebral leakage and 2 cases of intervertebral space leakage, and no clinical symptoms were observed in all the 6 cases. CT scanning showed that the bone cement was mainly distributed in the anterior 2/3 of the vertebral body. The maximum distribution area of bone cement was (4.5±0.9) cm2, with the contralateral area (2.0±0.5) cm2 and the puncture side area (2.5±0.7) cm2, which makes the ratio of the puncture side area versus contralateral area 0.85±0.27. (2) The anterior vertebral body heights preoperatively showed no significant difference than those postoperatively in 28 patients (P > 0.05). (3) The visual analogue scale score and Oswestry disability index 48 hours and 6 months postoperatively were both significantly different from those before operation (P < 0.05). (4) The results showed that percutaneous curved vertebroplasty treatment of osteoporotic vertebral compression fractures has the advantages of accurate surgical effects and even distribution of bone cement.

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：Patients with vertebral compression fracture first visit the acute care hospital for a diagnosis, but cannot be admitted and return home with a corset and analgesics. Because of severe lower back pain, they stay in bed for a significant period of time, and their skeletal muscles suffer from disuse atrophy. We aimed to actively admit these patients for recovery phase rehabilitation by setting up a hotline.Methods：The backgrounds of each case including the major laboratory findings were investigated for 1 year. Health professionals were able to use the hotline to request admission for the patients.Results：One hundred twenty-seven patients (38 males and 89 females, aged 84±7.5 years) were admitted. The percentages of phone calls from acute-care hospitals, clinics, and regional care managers were 46%, 31%, and 20%, respectively. With regard to degree of disability 36％ of the patients were at C1, 31% were at B2, and 20% were at C2 indicating that they needed almost complete assistance. Fifty one percent of the patients lived alone, and 20% were couples without assistance from others. Because they were elderly patients with many complications, more than six agents had been prescribed on average. However, osteoporosis medication had been prescribed to only 23%. The prognosis was favorable with ratio of returned home being 91%, even though the outcome of rehabilitation is limited by ageing and deteriorated cardiac and renal functions in these patients.Conclusion：Services to support these patients during the recovery phase of rehabilitation is crucial, in order to improve community-based health care.
ABSTRACT
Objective:To compare the effect and clinical significance of unilateral and bilateral percutaneous kyphoplasty (PKP) combined with hyperextension reduction in the treatment of fresh osteoporotic vertebral compression fracture (OVCF).Methods:The clinical data of OVCF patients treated in Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical University from January to December 2018 were retrospectively analyzed.A total of 62 patients were included.According to the surgical approach, 62 patients were divided into unilateral puncture approach group and bilateral puncture approach group, with 31 cases in each group.The patients in the unilateral puncture group were treated with limb hyperextension reduction combined with unilateral PKP.In the bilateral puncture approach group, limb hyperextension reduction combined with bilateral PKP was used.The changes of visual analogue pain scale (VAS), Oswestry disability index (ODI), vertebral anterior height, vertebral midline height and Cobb angle were observed and compared before operation, 1 day and 2 weeks after operation.At the same time, the operation time, intraoperative fluoroscopy times, intraoperative bone cement injection and adverse reactions were compared between the two groups.Results:The VAS scores of patients in the unilateral puncture approach group before operation, 1 day and 2 weeks after operation were (8.10±0.17), (2.20±0.26) and (1.90±0.39), respectively.The scores of bilateral puncture approach group were (8.10±0.13), (2.30±0.26) and (2.00±0.30), respectively.The results of repeated measurement ANOVA showed that F intra-group=13 790.444, P<0.001, F inter-group=1.951, P=0.168, F interaction=0.735, P=0.481.There were significant differences in VAS scores between the two groups 1 day and 2 weeks after operation (all P<0.05).

ABSTRACT
Introduction: Osteoporotic vertebral fractures that produce increased morbidity, persistent back pain, risk of collapse with time, and increased fracture risk. Subsequently, these vertebral fractures produce kyphotic deformity and effect on lung capacity. In our study purpose is to assess the clinical outcome, safety, and efficacy of transpedicular percutaneous vertebroplasty in osteoporotic vertebral compression fractures (VCFs). Methodology: The study done between December 2017 and December 2019 at our institute. Atotal of 10 patients with 21 vertebral body collapse in that 13 dorsal vertebra and 8 lumbar vertebral body included in the study in neurologically intact individuals. Patients are considered for treatment, those with chronic pain refractory to medical therapy and bracing and those with severe disabling pain caused by fractures. Severe cardiopulmonary disease, coagulopathy, and cord compression are contraindications to vertebroplasty. Severe vertebral compression may also be a contraindication to treatment, because the vertebra may be compressed to such a degree that needle placement and cement injection become impossible. After treatment, they selected one of three possible responses for each: Significantly improved, worse, or approximately the same. As an overall assessment analgesic requirement, visual analog scale, grading of subjective satisfaction score, sleep, and ambulation improvement assessed. To ensure uniformity despite the variable follow-up period, patients were instructed to indicate their status at 2 weeks after the procedure, 6 months, and 1-year follow-up. Results: Both pain and functional outcome improved significantly in immediate post-procedure at 2 weeks, 6 months, and 1 year. The majority (70%) of the patients were treated for 2 levels while 2 patients were treated for 3 levels and 1 patient was treated for 1 level. Visual analog scale (VAS) in the pre-procedure period is 8.3 which decrease in the post-procedure period at 2 weeks and 6 months is 2.6 and 3.6 subsequently and at 1-year average VAS score is 4. Mobility and sleep pattern is significantly improved in 8 patients (80%) at 1-year follow-up whereas remain same in 2 patients. Conclusion: Significant relief in pain in the post-procedure period with minimum risk noticed for VCFs.

ABSTRACT
Objective: To discuss the safety and effectiveness of the improved technique by comparing the effects of low temperature bone cement infusion before and after the improvement in the percutaneous vertebroplasty (PVP). Methods: The clinical data of 170 patients (184 vertebrae) with osteoporotic vertebral compression fracture who met the selection criteria between January 2016 and January 2018 were retrospectively analyzed. All patients were treated with PVP by low-temperature bone cement perfusion technology. According to the technical improvement or not, the patients were divided into two groups: the group before the technical improvement (group A, 95 cases) and the group after the technical improvement (group B, 75 cases). In group A, the patients were treated by keeping the temperature of bone cement at 0℃ and parallel puncture; in group B, the patients were treated by increasing the temperature of bone cement or reducing the time of bone cement in ice salt water and cross puncture. There was no significant difference in gender, age, disease duration, T value of bone mineral density, operative segment, and preoperative vertebral compression rate, visual analogue scale (VAS) score between the two groups ( P>0.05). CT examination was performed immediately after operation, and the leakage rate of bone cement was calculated. The amount of bone cement perfusion and the proportion of bone cement in contact with the upper and lower endplates at the same time were compared between the two groups. The vertebral compression rate was calculated and the VAS score was used to evaluate the pain before operation, at immediate after operation, and last follow-up. Results: There was no complication such as incision infection, spinal nerve injury, or pulmonary embolism in both groups. There was no significant difference in the amount of bone cement perfusion between groups A and B ( t=0.175, P=0.861). There were 38 vertebral bodies (36.89%) in group A and 49 vertebral bodies (60.49%) in group B exposed to bone cement contacting with the upper and lower endplates at the same time, showing significant difference ( χ2=10.132, P=0.001). Bone cement leakage occurred in 19 vertebral bodies (18.45%) in group A and 6 vertebral bodies (7.41%) in group B, also showing significant difference ( χ2=4.706, P=0.030). The patients in group A and group B were followed up (13.3±1.2) months and (11.5±1.1) months, respectively. The vertebral compression rates of the two groups at immediate after operation were significantly lower than those before operation ( P0.05). The VAS scores of the two groups at immediate after operation were significantly lower than those before operation ( P0.05). There was no significant difference in VAS scores between the two groups at immediate after operation ( t=0.380, P=0.705); but at last follow-up, VAS score in group B was significantly lower than that in group A ( t=3.627, P=0.000). Conclusion: The improved advanced low-temperature bone cement perfusion technology during PVP by increasing the viscosity of bone cement combined with cross-puncture technology, can reduce bone cement leakage, improve the distribution of bone cement in the vertebral body, and reduce the risk of vertebral collapse, and achieve better effectiveness.
ABSTRACT
Objective: To compare the effect of percutaneous kyphoplasty (PKP) with different phases bone cement for treatment of osteoporotic vertebral compression fracture (OVCF). Methods: The clinical data of 219 OVCF patients who treated with PKP and met the selection criteria between June 2016 and May 2018 were retrospectively analyzed. According to the different time of intraoperative injection of bone cement, they were divided into observation group [116 cases, intraoperative injection of polymethyl methacrylate (PMMA) bone cement in low-viscosity wet-sand phase)] and control group (103 cases, intraoperative injection of PMMA bone cement in low-viscosity wire-drawing phase). There was no significance in general date of gender, age, disease duration, body mass index, bone mineral density T value, fracture vertebral body, preoperative fracture severity of the responsible vertebral body, anterior height ratio of the responsible vertebral body, preoperative pain visual analogue scale (VAS) score, and Oswestry disability index (ODI) between the two groups ( P>0.05). The VAS score and ODI score were used to evaluate the improvement of patients' symptoms at immediate, 2 days, 3 months after operation and at last follow-up. At 1 day, 3 months after operation, and at last follow-up, X-ray film and CT of spine were reexamined to observe the distribution of bone cement in the vertebral body, bone cement leakage, and other complications. During the follow-up, the refracture rate of the responsible vertebral body and the fracture rate of the adjacent vertebral body were recorded. Results: The injection amount of bone cement in the observation group and control group were (4.53±0.45) mL and (4.49±0.57) mL, respectively, showing no significant difference between the two groups ( t=1.018, P=0.310). Patients in both groups were followed up 6-18 months (mean, 13.3 months). There were 95 cases (81.9%) and 72 cases (69.9%) of the bone cement distribution range more than 49% of the cross-sectional area of the vertebral body in the observation group and the control group, respectively, showing significant difference in the incidence between the two groups ( χ2=4.334, P=0.037). The VAS score and ODI score of the postoperative time points were significantly improved compared with those before operation ( P0.05). At 1 day after operation, the cement leakage occurred in 18 cases of the observation group (8 cases of venous leakage, 6 cases of paravertebral leakage, 4 cases of intradiscal leakage) and in 22 cases of the control group (9 cases of venous leakage, 8 cases of paravertebral leakage, 5 cases of intradiscal leakage). There was no significant difference between the two groups ( P>0.05). During the follow-up, 5 cases (4.3%) in the observation group, 12 cases (11.7%) in the control group had responsible vertebral refracture, and 6 cases (5.2%) in the observation group and 14 cases (13.6%) in the control group had adjacent vertebral fracture, the differences were significant ( χ2=4.105, P=0.043; χ2=4.661, P=0.031). Conclusion: Bone cement injection with wet-sand phase in PKP is beneficial for the bone cement evenly distributed, strengthening the responsible vertebral, relieving the short-term pain after operation, decreasing the rate of responsible vertebral refracture and adjacent vertebral fracture without increasing the incidence of relevant complications and can enhance the effectiveness.
ABSTRACT
Objective: To evaluate the safety and effectiveness of robot-guided percutaneous kyphoplasty (PKP) in treatment of multi-segmental thoracolumbar osteoporotic vertebral compression fracture (OVCF). Methods: A clinical data of 63 cases with multi-segmental thoracolumbar OVCF without neurologic deficit treated with PKP between October 2017 and February 2019 were analyzed retrospectively. The patients were divided into robot-guided group (33 cases) and traditional fluoroscopy group (30 cases). There was no significant difference in gender, age, fracture segment, bone mineral density, and preoperative visual analogue scale (VAS) score, midline vertebral height, and Cobb angle between the two groups ( P>0.05). The time to establish the tunnel, the times of fluoroscopy, the dose of fluoroscopy, the deviation of puncture, the distribution of bone cement, the leakage of bone cement, the puncture angle, and the postoperative VAS score, midline vertebral height, and Cobb angle were recorded and compared. Results: The patients in two groups were followed up 11-13 months (mean, 12 months). Compared with traditional fluoroscopy group, the time to establish the tunnel, the times and dose of fluoroscopy in robot-guided group were significantly lower, the deviation of puncture was slighter, the distribution of bone cement was better, and the puncture angle was larger, the differences between the two groups were significant ( P0.05). Conclusion: Robot-guided PKP in treatment of multi-segmental thoracolumbar OVCF can shorten the operation time, improve the accuracy of puncture, reduce the times and dose of fluoroscopy, reduce the leakage of bone cement, and achieve better cement distribution.
