Chang KC, Huang CT, Hsieh CT, Chen CM, Chang CJ. Risk factors for bone cement dislodgement following balloon kyphoplasty for osteoporotic vertebral compression fracture. Neurochirurgie 2024; 70:101559. [PMID: 38614310 DOI: 10.1016/j.neuchi.2024.101559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 04/01/2024] [Accepted: 04/02/2024] [Indexed: 04/15/2024]
Abstract
OBJECTIVE The study aimed to determine the incidence and risk factors associated with bone cement dislodgement in patients with osteoporotic vertebral compression fracture following balloon kyphoplasty treatment. METHODS A retrospective study was conducted on 203 patients who underwent kyphoplasty in 255 vertebral bodies between January 2017 and December 2021. The patients were categorized into two groups: the bone cement dislodgment group (n = 16) and the non-bone cement dislodgement group (n = 239). Various patient characteristics and radiologic parameters were evaluated. Statistical analysis involved the assessment of the background homogeneity of the group by using independent sample t tests, chi-square tests, and Fisher's exact. Univariate and multivariate logistic regression analyses were performed to explore the impact of background variables on cement dislodgement. RESULTS The results revealed that split-type fracture (χ2 = 31.706, p < 0.001), DISH (χ2 = 18.827, p = 0.011), pedicle fracture (χ2 = 22.246, p < 0.001), endplate deficit (χ2 = 14.023, p < 0.001), posterior wall injury (χ2 = 29.124, p < 0.001), and intervertebral vacuum cleft (χ2 = 21.469, p < 0.001) were the factors that significantly differed between the two groups. The multivariate logistic regression analysis revealed posterior wall injury (OR = 12.983, p = 0.025) and intervertebral vacuum cleft (OR = 5.062, p = 0.024) to be independent risk factors. CONCLUSION The incidence of bone cement dislodgement in our study was 6.3%. This study underscores the importance of using preoperative radiologic parameters to predict the risk of bone cement dislodgement following balloon kyphoplasty.

A Comparative Study of 2 Techniques to Avoid Bone Cement Loosening and Displacement After Percutaneous Vertebroplasty Treating Unstable Kummell Disease. Neurospine 2024; 21:575-587. [PMID: 38763157 PMCID: PMC11224748 DOI: 10.14245/ns.2347274.637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 02/21/2024] [Accepted: 02/22/2024] [Indexed: 05/21/2024] Open
Abstract
OBJECTIVE Percutaneous vertebroplasty (PVP) is currently the most common surgical procedure for unstable Kummell disease (KD), but cement loosening or displacement often occurs after PVP. We had been using percutaneous pediculoplasty (PPP) or a self-developed bone cement bridging screw system to avoid this severe complication. This study intends to compare these novel surgical procedures through a 2-year follow-up evaluation. METHODS From May 2017 to May 2021, 77 patients with single-level unstable KD were included in the PPP group, and 42 patients received the PVP-bone cement bridging screw system were included in the screw group. The changes in the vertebral body index (VBI), bisegmental Cobb angle, visual analogue scale (VAS) and Oswestry Disability Index (ODI) and the cement loosening rate and displacement rate at different follow-up time points were used to evaluate the clinical efficacy. RESULTS There was no significant difference in VBI or bisegmental Cobb angle between the 2 groups (p > 0.05) before operation, immediately after operation and at 6-month followup, while at 1-year and 2-year postoperative evaluations, the screw group had higher VBI and bisegmental Cobb angle than the PPP group (p < 0.05). Before operation, immediately after operation, at 6-month and 1-year follow-up, there was no significant difference in VAS or ODI score between the 2 groups (p > 0.05), while at 2-year follow-up, the screw group still had higher VAS and ODI scores than the PPP group (p < 0.05). No bone cement displacement occurred in both groups, but the rate of bone cement loosening was 14.29% in group PPP, and 0 in screw group (p < 0.05). CONCLUSION This 2-year follow-up study shows that the PVP-bone cement bridging screw system combined therapy had better midterm treatment efficacy than the PVP-PPP combined therapy in patients with unstable KD, and the bone cement bridging screw system is a preferred therapy with better anti cement loosening ability.

Prevention of Bone Cement Displacement in Kümmell Disease without Neurological Deficits through Treatment with a Novel Hollow Pedicle Screw Combined with Kyphoplasty. Orthop Surg 2023; 15:2515-2522. [PMID: 37537414 PMCID: PMC10549841 DOI: 10.1111/os.13815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 06/04/2023] [Accepted: 06/08/2023] [Indexed: 08/05/2023] Open
Abstract
OBJECTIVE Displacement of bone cement following percutaneous vertebral augmentation for Kümmell disease (KD) presents a significant concern, resulting in increasing back pain and compromising daily activities. Unfortunately, current literature does not yet establish a validated and minimally invasive surgical intervention for this issue. This study aims to investigate the effects of a novel hollow pedicle screw combined with kyphoplasty (HPS-KP) in preventing bone cement displacement following simply percutaneous kyphoplasty for the management of KD. METHODS A total of 22 patients (six males, 16 females, averagely aged 77.18 ± 7.63 years) with KD without neurological deficits treated by HPS-KP at the hospital between March 2021 and June 2022 were hereby selected, among which, there were three stage I KD cases, 12 stage II KD cases, and seven stage III KD cases according to Li's classification. Bone mineral density (BMD), spinal X-ray, computed tomography (CT), and magnetic resonance imaging (MRI) were examined before the operation. The operation time, intraoperative blood loss, and postoperative complications were all recorded. The follow-up focused on visual analog scale (VAS) score, Oswestry dysfunction index (ODI), anterior vertebral height (AVH), middle vertebral height (MVH), posterior vertebral height (PVH), wedge-shape affected vertebral Cobb angle (WCA), and bisegmental Cobb angle (BCA). One-way analysis of variance (ANOVA) followed by Bonferroni post-hoc test was employed for performing multiple comparisons in the present study. RESULTS All patients having received the operation successfully were followed up for more than 8 months (ranging from 8 to 18 months). The operation time, intraoperative blood loss, and BMD (T-score) were 39.09 ± 5.64 min, 14.09 ± 3.98 ml, and - 3.30 ± 0.90 g/cm3 , respectively. Statistically significant differences were observed in the VAS score, ODI, AVH, MVH, and WCA (All p < 0.05), but there was no statistically significant difference in PVH and BCA at different time points (All p > 0.05). During follow-up, five patients suffered from bone cement leakage, and one presented an adjacent vertebral fracture and no bone cement displacement. CONCLUSION HPS-KP could be safe and effective in the treatment of KD without neurological deficits, effectively relieving the symptoms of patients, restoring partial vertebral height, and preventing the occurrence of bone cement displacement.

Biomechanical analysis of a novel bone cement bridging screw system combined with percutaneous vertebroplasty for treating Kummell's disease. Front Bioeng Biotechnol 2023; 11:1077192. [PMID: 37274166 PMCID: PMC10233143 DOI: 10.3389/fbioe.2023.1077192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Accepted: 05/09/2023] [Indexed: 06/06/2023] Open
Abstract
Kummell's Disease (KD) was originally proposed by Dr. Hermann Kummell in 1891 as a type of delayed posttraumatic vertebral collapse, which is a clinical phenomenon. The purpose of this experiment is to compare the strength of bone cement and the novel bone cement bridging screw in the treatment of thoracolumbar Kummell disease (KD) with other treatment methods. Thirty sheep spine specimens were selected. T12 to L2 segments were selected, and a KD intravertebral vacuum cleft model was made at the L1 segment. According to the ways of cement filling, the specimens were divided into percutaneous vertebroplasty (PVP), PVP combined with unilateral percutaneous pediculoplasty (PPP), PVP combined with bilateral PPP, unilateral novel bone cement bridging screw system combined with PVP, and bilateral cement bridging screw system combined with PVP groups. There were two experiments: three-dimensional biomechanical strength test and axial compression test. In the three-dimensional biomechanical strength test, we measured the strength of bone cement in specimens under six motion states, including flexion, extension, left bending, right bending, and left and right axial rotations. In the axial compression test, we detected the maximum axial pressure that the bone cement could withstand when it was under pressure until the bone cement was displaced. The unilateral or bilateral novel bone cement bridging screw with PVP groups had the best strength under flexion, extension, left bending, right bending, and had better biomechanical strength, with a significant difference from the other three groups (p < 0.05). There was no significant difference between the unilateral or bilateral novel bone cement bridging screw with PVP groups (p > 0.05). Unilateral and bilateral novel bone cement bridging screw could achieve similar bone cement strength. Compared with the other three groups, the unilateral or bilateral novel bone cement bridging screw with PVP groups are higher 136.35%, 152.43%; 41.93%, 51.58%; 34.37%, 43.50% respectively. The bilateral novel bone cement bridging screw with PVP could bear the largest pressure under vertical force. To conclude, the novel bone cement bridging screw can increase the strength of bone cement and avoid the loosening and displacement of bone cement in the treatment of KD of the thoracolumbar spine.

Predictive Factors for Bone Cement Displacement following Percutaneous Vertebral Augmentation in Kümmell's Disease. J Clin Med 2022; 11:jcm11247479. [PMID: 36556095 PMCID: PMC9783310 DOI: 10.3390/jcm11247479] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 11/21/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
Objective: To investigate the independent influencing factors of bone cement displacement following percutaneous vertebral augmentation (PVA) in patients with stage I and stage II Kümmell’s disease. Methods: We retrospectively reviewed the records of 824 patients with stage Ⅰ and stage Ⅱ Kümmell’s disease treated with percutaneous vertebroplasty (PVP) or percutaneous vertebroplasty (PKP) from January 2016 to June 2022. Patients were divided into the postoperative bone cement displacement group (n = 150) and the bone cement non-displacement group (n = 674) according to the radiographic inspection results. The following data were collected: age, gender, body mass index (BMI), underlying disease, bone mineral density (BMD), involved vertebral segment, Kümmell’s disease staging, anterior height, local Cobb angle, the integrity of anterior vertebral cortex, the integrity of endplate in surgical vertebrae, surgical method, surgical approach, the volume of cement, distribution of cement, the viscosity of cement, cement leakage, and postoperative anti-osteoporosis treatment. Binary logistic regression analysis was performed to determine the independent influencing factors of bone cement displacement. The discrimination ability was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC). Results: The results of logistic regression analysis revealed that thoracolumbar junction (odds ratio (OR) = 3.23, 95% confidence interval (CI) 2.12−4.50, p = 0.011), Kümmell’s disease staging (OR = 2.23, 95% CI 1.81−3.41, p < 0.001), anterior cortex defect (OR = 5.34, 95% CI 3.53−7.21, p < 0.001), vertebral endplates defect (OR = 0.54, 95% CI 0.35−0.71, p < 0.001), cement distribution (OR = 2.86, 95% CI 2.03−3.52, p = 0.002), cement leakage (OR = 4.59, 95% CI 3.85−5.72, p < 0.001), restoration of local Cobb angle (OR = 3.17, 95% CI 2.40−5.73, p = 0.024), and postoperative anti-osteoporosis treatment (OR = 0.48, 95% CI 0.18−0.72, p = 0.025) were independently associated with the bone cement displacement. The results of the ROC curve analysis showed that the AUC was 0.816 (95% CI 0.747−0.885), the sensitivity was 0.717, and the specificity was 0.793. Conclusion: Thoracolumbar fracture, stage Ⅱ Kümmell’s disease, anterior cortex defect, uneven cement distribution, cement leakage, and high restoration of the local Cobb angle were risk factors for cement displacement after PVA in Kümmell’s disease, while vertebral endplates defect and postoperative anti-osteoporosis treatment are protective factors.

Percutaneous Cement-Augmented Screws Short Fixation for the treatment of Severe Osteoporotic Vertebral Burst Fractures. World Neurosurg 2022; 163:e522-e531. [PMID: 35427793 DOI: 10.1016/j.wneu.2022.04.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 04/04/2022] [Accepted: 04/05/2022] [Indexed: 10/18/2022]
Abstract
OBJECTIVE (BACKGROUND) This study aims to evaluate the therapeutic reliability of posterior percutaneous cement-augmented screws short fixation(PASF) in patients with severe osteoporotic vertebral burst fractures(OVBFs). METHODS Single-level OVBFs with an anterior vertebral body height(VBH) reduction equal or superior to 60% were included. A frailty index was employed for preoperative frailty assessment. Back pain and related disability were assessed through the VAS scale and Oswestry low-back pain disability index(ODI), being administered at injury time, preoperative, postoperative, twelfth-month and last patient follow-up evaluations. The main radiological outcomes were represented by Cobb angle(CA) and anterior vertebral body compression percentage(AVBC%), being measured at injury time, preoperative, postoperative and twelfth-month examinations. Among the others, the incidence of cement leakages and hardware failures was assessed. RESULTS Thirty-three patients met the inclusion criteria. All patients resulted frail(76%) or semi-frail(24%). Significant VBH restoration and segmental kyphosis improvement after PASF was documented (AVBC%:-40(-43;-37) VS -67(-70;-65), P = 0.0001; CA: 10(8-12) VS 24(23-26), P = 0.0001). The mean VAS and ODI scores documented optimal and long-enduring pain relief and related disability reduction after PASF (VAS: 2(2-3) VS 8(7-8), P = 0.0001; ODI: 22(17-26) VS 64(60-69), P = 0.0001). Only one cement leakage (3%), asymptomatic, occurred. After a mean follow-up of 33 months, no early/late hardware failures were reported. CONCLUSIONS The clinical and radiological results of this study suggest that PASF could be a safe and effective treatment option for severe OVBFs when conservative treatments failed.

Abstract
Objective This study aimed to evaluate the efficacy and safety of modified posterior vertebral column resection (PVCR) combined with anterior column restoration in elderly patients presenting with thoracic or thoracolumbar osteoporotic fractures with spinal cord compression and severe pain.
Methods One hundred nine patients with one level thoracolumbar osteoporotic fracture and at least 5 years of follow-up were included. They underwent posterior instrumentation performed with polymethymetachrylate augmented pedicle screws. A modified PVCR (unilateral costotransversectomy+hemilaminectomy) combined with the insertion of an expandable titanium cage for anterior column restoration was undertaken. Patients were evaluated clinically and radiographically.
Results Patients had a mean age of 74.1 and a follow-up duration of 92.3 months. Mean duration of operations, hospital stays, and mean loss of blood were 172.3 minutes, 4.3 days, and 205.4 mL. All of the patients were mobilized immediately after surgery. The mean preoperative local kyphosis angle improved from 39.3° to 4.7° at the last follow-up (p = 0.003). Patients preoperative mean visual analogue score, Japanese Orthopaedic Association, and Oswestry Disability Index scores improved from 7.7/8.6/76.3 to 1.6/26.1/17.4 (p < 0.001 for all), respectively. The average 36-item Short-Form survey physical component summary/mental component summary scores at the last follow-up were 55.1/56.8. A dural tear was detected intraoperatively in 1 patient and repaired immediately.
Conclusion Subtotal PVCR combined with the insertion of an expandable titanium cage was detected as a safe and effective method for osteoporotic vertebrae fractures’ sequelae in the older population involving spinal cord compression by enabling the decompression of the spinal canal and reconstruction of the resected segment, resulting in significant improvement in clinical and radiographic outcomes.

A novel bone cement screw system combined with vertebroplasty for the treatment of Kummell disease with bone deficiency at the vertebral anterior border: A minimum 3-year follow-up study. Clin Neurol Neurosurg 2020; 201:106434. [PMID: 33370625 DOI: 10.1016/j.clineuro.2020.106434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 12/02/2020] [Accepted: 12/10/2020] [Indexed: 10/22/2022]
Abstract
OBJECTIVES When vertebroplasty is used to treat Kummell disease with bone deficiency at the vertebral anterior border, bone cement displacement often occurs intraoperatively or postoperatively. We designed and used a new bone cement screw system to avoid this serious complication. The purpose of this study was to evaluate the safety and effectiveness of this novel operation method through more than 3 years of follow-up. PATIENTS AND METHODS From January 2014 to August 2016, 27 patients suffering from single-segment Kummell disease with bone deficiency at the vertebral anterior border were treated by vertebroplasty combined with a novel bone cement screw. Bone cement was released into the diseased vertebrae through the screw to fully fill the intravertebral vacuum cleft. Screw fixation of bone cement can avoid intraoperatively or postoperatively displacement. All patients received surgery involving a unilateral technique, and only one screw was implanted in each patient. The clinical efficacy was evaluated using Odom's criteria and statistical analysis of the vertebral body index (VBI), vertebral body angle (VBA), bisegmental Cobb angle (BCA), visual analogue scale (VAS), Oswestry disability index (ODI), and the results of the MOS 36-item short form health survey (SF-36). RESULTS The operation was completed successfully in 27 cases. The average operation time was 49.63 ± 10.82 min, and the average volume of cement injected was 4.70 ± 0.87 mL. The patients' preoperative VBI, VBA, BCA, VAS and ODI scores were 43.11 ± 5.94, 21.04 ± 2.55, 45.00 ± 6.26, 7.59 ± 0.84, and 79.85 ± 7.58, respectively. The postoperative measurements were 78.70 ± 2.55, 12.70 ± 2.11, 26.11 ± 4.73, 3.22 ± 0.93 and 50.04 ± 9.28, respectively. At the last follow-up, the measurements were 78.04 ± 2.30, 13.15 ± 2.38, 27.07 ± 4.87, 2.04 ± 0.65, and 22.85 ± 5.06, respectively. There was a significant difference between the preoperative and postoperative data, as well as the preoperative and the last follow-up data (P < 0.05). Comparing the results of SF-36 before operation and at the last follow-up revealed significant differences in physical function, role-physical, body pain, vitality, and social function (P < 0.05). However, there were no significant differences in general health, emotional function and mental health. Finally, 26 patients (96.3 %) had good to excellent clinical outcomes according to Odom's criteria. CONCLUSIONS This 3-year follow-up study shows that the novel bone cement screw system combined with vertebroplasty has a good short and medium-term therapeutic effect in patients with Kummell disease and bone deficiency at the vertebral anterior border, while its long-term efficacy is subject to further studies.

Abstract
Objective We investigated the clinical and radiological outcomes of a cement augmented anterior reconstruction and decompression without pedicle screw fixation in patients with osteoporotic thoracolumbar vertebral fracture with myelopathy. Methods There were 2 male and 6 female patients with thoracolumbar fracture and myelopathy included in the study. The mean follow-up period was more than 1 years. The anterolateral decompression and cement augmented anterior reconstruction with poly(methyl methacrylate) (PMMA) was performed. Demographic data, clinical outcomes, perioperative parameters and radiologic parameter were retrospectively evaluated. Results The symptoms due to myelopathy were improved in all patients. The preoperative median visual analog scale score for lower back and leg were 8.5 that improved 4.25 and 3 at last follow up. The preoperative function state showed a median Oswestry Disability Index score 61.5 that improved 33. After surgery, preoperative encroachment of the spinal canal (5.12 mm, 37%) was disappeared. The median height of fractured vertebral body significantly increased from 7.83 to 12.63 mm. At the last follow-up point, the median height was 9.91 mm. The median kyphotic deformity was improved from 22.12° to 14.31°. At the final follow-up, the improvement was preserved (median value: 15.03). The acute complication according to PMMA such as leakage and embolization was none, but adjacent compression fracture as late complication according to cement augmentation was. One patient developed surgical site infection. Conclusion On the basis of the preliminary results, we considered that anterolateral decompression and PMMA augmentation might be an optimal method for treating osteoporotic fracture with myelopathy in elderly patients or those with multiple medical comorbidities.

Abstract
STUDY DESIGN This was a retrospective study. OBJECTIVE Severe osteoporotic vertebral compression fractures with kyphotic deformity are difficult to treat. The objective of this study was to investigate the clinical efficacy of posterior vertebral column resection (PVCR) combined with bone cement augmentation of pedicle screw fixation in the treatment of severe vertebral compression fractures with kyphotic deformity. SUMMARY OF BACKGROUND DATA The data of patients with a severe vertebral compression fracture and kyphotic deformity treated at our university between October 2013 and October 2017 were retrospectively reviewed. MATERIALS AND METHODS All patients underwent PVCR combined with bone cement augmentation of pedicle screw fixation and anterior column reconstruction. The operative time, intraoperative blood loss, postoperative complications, and screw stability at the last follow-up in all patients were documented. The clinical benefits were evaluated by the Visual Analog Scale (VAS) score, Oswestry Dysfunction Index (ODI), Japanese Orthopedic Association (JOA) scores, and Frankel classification. RESULTS The mean Cobb angle, sagittal vertical axis, VAS score, JOA score, and ODI were 48.5±6.9 degrees, 44.0±5.7, 6.5±1.5, 11.2±2.7, and 59.0±5.7 before surgery, respectively. The average follow-up period was 28.7±3.2 months. The Frankel grade in 5 patients with neurological impairment improved from D to E after surgery. The average Cobb angles for kyphotic deformity, sagittal vertical axis, VAS score, JOA score, and ODI were 9.5±3.8 degrees, 18.3±3.5, 2.6±1.2, 20.5±3.6, and 20.7±4.0, respectively, at the last follow-up (all P<0.05 compared with before surgery). CONCLUSIONS For patients with severe vertebral compression fractures and kyphotic deformity, PVCR combined with bone cement augmentation of pedicle screw fixation can restore the spine sequence to achieve good clinical efficacy. Clinical trials are necessary for confirmation.

[PMID: 32265470 PMCID: PMC7138790 DOI: 10.1038/s41598-020-62869-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2019] [Accepted: 03/16/2020] [Indexed: 01/28/2023] Open
Abstract
Refracture of cemented vertebrae occurs commonly after vertebroplasty (VP) for osteoporotic vertebral compression fracture (OVCF). It can result in severe pain or neurological deficit, but no preventive medication is available. Owing to the bone anabolic benefits of teriparatide (TP), this study was aimed to compare the outcomes of cemented vertebrae with TP to those without TP. Patients who received VP for OVCF with at least 1 year follow-up were included. The anterior body height (ABH) and middle body height (MBH) and kyphotic angle (KA) were measured before VP and 1 week and at least 1 year after VP. Refracture was defined as a 15% decrease in ABH or MBH and 8° decrease in KA compared with those at postoperative 1 week. The clinical outcomes were evaluated. 35 VP procedures in 21 patients treated with TP (TP group), and, matched to that, 29 out of 133 patients treated with VP alone (VP group) were included. One year after VP, ABH and MBH were significantly greater, except KA, in the TP group (VP group vs. TP group: KA - 4.97° ± 12.1 vs. -2.85° ± 12.21°, p = 0.462, ABH 1.56 ± 0.48 cm vs. 1.84 ± 0.56 cm, p = 0.027, MBH 1.49 ± 0.39 cm vs. 1.73 ± 0.41 cm, p = 0.017). The refracture rates of KA, ABH, and MBH were significantly lower in the TP group (VP group vs. TP group: KA 42.11% vs.8.57%, p < 0.001; ABH 76.32% vs. 28.57%, p < 0.0001; MBH 76.32% vs. 28.57%, p < 0.0001). In single-level subgroup comparison, TP was associated with better improvement of pain VAS and better radiological outcomes. TP was associated with higher BHs and fewer refractures than VP alone, with comparable clinical outcomes 1 year after VP. TP may be associated with better improvement of pain VAS in those with single-level VP procedure. Higher BH was due to the better maintenance effect of TP.

Abstract
PURPOSE Define the effectiveness of teriparatide (TPTD) treatment on reducing the incidence of new vertebral compression fractures (NVCFs) and back pain and improving quality of life after percutaneous kyphoplasty (PKP). METHODS Two years of clinical follow-up data from primary osteoporotic women who had experienced initial osteoporotic vertebral compression fractures (OVCFs) and received PKP plus 12-month TPTD (n=113) or basic treatment (BT) of calcium and vitamin D supplements (n=208) were retrospectively collected. The risk of NVCFs over each 6-month period in the TPTD group was evaluated and compared with the BT group using a logistic regression. Health-related quality of life (HRQoL, EQ-5D questionnaire), back pain [100 mm visual analog scale (VAS)] and bone mineral density (BMD) of the spine were analyzed using linear mixed models for repeated measures (LMMRM). RESULTS Logistic regression analysis adjusting for baseline characteristics showed that patients in the TPTD group had a lower risk of NVCFs compared with those receiving BT during the final three observation intervals (6-12 months, OR=0.189, 95% CI=0.030-0.681, p=0.046; 12-18 months, OR=0.009, 95% CI=0.0001-0.111, p=0.001; 18-24 months, OR=0.024, 95% CI=0.0009-0.264, p=0.009, respectively). Significant improvements in adjusted EQ-5D and back pain VAS scores were identified in the TPTD group compared with the BT group, and this improvement was sustained for at least 12 months after teriparatide treatment was discontinued (both p<0.001). The BMD of the spine also showed a higher T-value in the TPTD group compared with the BT group (p<0.001). CONCLUSION In routine clinical practice, for patients with OVCFs who receive the PKP procedure, TPTD treatment may be a preferable subsequent therapy because of its ability to reduce the incidence of NVCFs and sustain a high quality of life and back pain alleviation.

Abstract
UNLABELLED We assessed the safety and feasibility of a unified conservative treatment protocol for osteoporotic vertebral fractures in the elderly patients with a 24-week follow-up. Our results showed that initial hospitalization with rigorous bed rest followed by a rehabilitation program using a Jewett brace was safe and feasible in managing patients. PURPOSE The purpose of this study was to prove the safety and feasibility of a unified conservative treatment protocol, which included initial hospitalization with rigorous bed rest followed by a rehabilitation program with Jewett brace for osteoporotic vertebral fractures (OVFs) in the elderly patients with a 24-week follow-up. METHODS Between April 2012 and Mach 2015, one hundred fifty-four patients met the eligibility for this study. Radiological findings at the 3-week, 6~8-week, 24-week assessment were evaluated. Among these, 11 patients underwent early surgery within the first 2 weeks after admission and 19 patients lost follow-up. Therefore, 124 patients were assessed at the final follow-up visit. RESULTS The average vertebral instability in all the present series was 4.9 ± 4.8° at 3-week, 2.9 ± 3.5° at 6~8-week, and 1.8 ± 3.0° at 24-week follow-up visit. Delayed union was observed in 16 patients on the 24-week follow-up visit. Therefore, the present conservative treatment protocol resulted in bony union in 98 out of 124 patients (79.0%, per protocol set analysis) and 98 out of 154 patients including drop-out (63.6%, intention-to-treat analysis). There was no severe adverse event related to initial bed rest. The vertebral instability at 3-week assessment was significantly higher in the delayed union group when compared with that in the union group. Univariate analyses followed by multivariate logistic regression analysis revealed that T2-weighted image of confined high intensity on MRI and having more than 5° of vertebral instability on dynamic X-ray at 3-week assessment are the independent risk factors for delayed union of conservative treatment in the present series. CONCLUSIONS Our results showed that initial hospitalization with rigorous bed rest followed by a rehabilitation program using a Jewett brace was safe and feasible. Therefore, the present conservative treatment protocol can be one of the acceptable treatment options in managing OVF patients.

Abstract
PURPOSE This study compared the radiologic and clinical outcomes of kyphoplasty with intravertebral reduction device (IRD) and vertebroplasty (VP) in treating osteoporotic vertebral compression fractures (OVCFs). MATERIALS AND METHODS We enrolled 75 patients with OVCFs who were aged >60 years and treated them through VP or kyphoplasty with IRD. The radiologic outcomes, namely the anterior and middle body heights (ABH and MBH, respectively) and kyphotic angle (KA), were measured preoperatively and at postoperative 1 week, 3 months, 6 months, and 1 year. The refracture was identified on the basis of a decrease in ABH, MBH, or KA compared with those at postoperative 1 week. Visual analog scale (VAS) for pain and complications were recorded. The incidence of adjacent and nonadjacent fractures was also recorded. RESULTS We treated 36 patients with kyphoplasty with IRD (IRD group) and 39 through VP (VP group). The patient characteristics were comparable in both groups. The KA and its restoration were more favorable after IRD than after VP. Although ABHs were not different in either group, their restoration was more efficient after IRD than after VP. MBHs, their restoration, and their refracture rates were better after IRD than after VP. VAS pain scores and complication rates were not different between the groups. The incidences of adjacent or nonadjacent fractures were not different between the 2 groups. CONCLUSION Our findings reveal significantly more efficient height restoration and kyphosis correction and fewer refractures in the IRD group. IRD may not increase the risk of adjacent or nonadjacent fractures.

Abstract
STUDY DESIGN A single-center retrospective study. OBJECTIVE To identify the relevant incidence and risk factors of delayed vertebral collapse and progressive kyphosis with spinal canal encroachment after percutaneous vertebroplasty (PVP) for vertebral compression fracture (VCF). SUMMARY OF BACKGROUND DATA Delayed vertebral collapse and progressive kyphosis with spinal canal encroachment are complications after PVP for VCF. METHODS Between December 2002 and February 2011, 843 patients underwent PVP for VCFs for at least 2 years of minimum follow-up term in a tertiary referral center. All imaging measurements were obtained digitally, with comparisons of the Cobb angle and spinal canal stenosis on fractured vertebral level at 3 different time points of pre- and postvertebroplasty, and before revision surgery. RESULTS Thirteen patients (14 fractures) who underwent PVP had delayed vertebral collapse and progressive kyphosis on the level of the fractured vertebra, 3 were male and 10 female, with a median age of 75 years (range, 66-89 yr). One had 2-level VCFs. All were treated with revision surgery of decompressive laminectomy for spinal canal stenosis with neurological complications. Twelve patients had additional instrument fixation. The involved vertebras were concentrated at the thoracolumbar junction region (T11-L2). The mean Cobb angles were measured at 23.67° before PVP, 15.90° after PVP, and 30.92° before revision surgery. The ratio of spinal canal stenosis was 35.45% and 49.48% before PVP and revision surgery, respectively. The occurrence rate of delayed complications was about 1.5% (13/843). CONCLUSION Conservative treatment and minimal invasive vertebral augmentation surgery can be selected from patients with stable VCFs. Close follow-up is warrant to monitor the occurrence of late collapse with neurological complications. LEVEL OF EVIDENCE N/A.

Abstract
OBJECTIVE Percutaneous vertebroplasty (PVP) is an effective treatment modality for management of osteoporotic compression fracture. However physicians sometimes have problems of high pressure in cement delivery and cement leakage when using Jamshidi® needle (JN). Bone void filler (BVF) has larger lumen which may possibly diminish these problems. This study aims to compare the radiologic and clinical outcome of JN and BVF for PVP. METHODS One hundred twenty-eight patients were treated with PVP for osteoporotic vertebral compression fracture (VCF) where 46 patients underwent PVP with JN needle and 82 patients with BVF. Radiologic outcome such as kyphotic angle and vertebral body height (VBH) and clinical outcome such as visual analog scale (VAS) scores were measured after treatment in both groups. RESULTS In JN PVP group, mean of 3.26 cc of polymethylmethacrylate (PMMA) were injected and 4.07 cc in BVF PVP group (p<0.001). For radiologic outcome, no significant difference in kyphotic angle reduction was observed between two groups. Cement leakage developed in 6 patients using JN PVP group and 2 patients using BVF group (p=0.025). No significant difference in improvement of VAS score was observed between JN and BVF PVP groups (p=0.43). CONCLUSION For the treatment of osteoporotic VCF, usage of BVF for PVP may increase injected volume of cement, easily control the depth and direction of PMMA which may reduce cement leakage. However, improvement of VAS score did not show difference between two groups. Usage of BVF for PVP may be an alternative to JN PVP in selected cases.
