Pathology and Acute Phase Treatment of Osteoporotic Vertebral Fractures:Indications and Techniques for Vertebroplasty

Vertebroplasty has shown excellent analgesic effects in patients with osteoporotic vertebral fractures. In Japan, percutaneous vertebroplasty, balloon kyphoplasty, and vertebral body stenting are commonly performed. All of these techniques require precise transpedicular vertebral puncture and complete cement filling without leakage. Puncture should only be performed after accurately identifying the upper and lower end plates of the vertebral body, lateral borders, and pedicles using combined frontal and lateral fluoroscopic images. In the frontal view, the puncture was made from the lateral cranial side of the pedicle toward the center of the vertebral body. In the lateral view, before passing through the medial wall, the tip had entered the vertebral body and advanced to the anterior quarter. Bone cement within the vertebral body can permeate the trabecular spaces or accumulate as a single mass. To prevent leakage, the movement of the injecting finger should be aligned precisely with the fluoroscopic images. Awareness of the three leakage patterns and basivertebral, segmental, and cortical veins, is crucial. Potential lateral leakage outside the vertebral body must be focused. The injection was terminated as the cement reached the posterior quarter.

Is orthotic treatment beneficial for fresh osteoporotic vertebral fractures? A propensity score matching study

BACKGROUND CONTEXTOrthotic treatment is a common option for the conservative treatment of osteoporotic vertebral fractures (OVF). However, there is insufficient evidence of its clinical benefit. PURPOSETo investigate the effectiveness of orthotic treatment for OVF. STUDY DESIGN/SETTINGRetrospective cohort study with data from two prospective studies. PATIENT SAMPLEThis study included 160 patients with fresh OVF enrolled in 2012 and 2020 prospective cohort studies. OUTCOME MEASURESThe visual analog scale (VAS) score for low back pain was used for clinical outcomes, and radiographic parameters included the percent height of the vertebra and angular change of the vertebral body. Moreover, the occurrence of secondary vertebral fractures was followed-up over time. METHODSThe patients were divided into brace and no-brace groups and were matched according to propensity score for age, sex, anterior percent height at the initial examination, and presence of old OVFs. Hazard ratio for the cumulative incidence of secondary vertebral fractures with and without bracing were calculated and analyzed using the generalized Wilcoxon test. In addition, the brace group was divided into soft and rigid brace groups and compared with the no-brace group. RESULTSEach group had 61 cases after propensity score matching. There were no significant differences in the VAS improvement for low back pain and the change in percent height of the anterior and posterior walls from initial examination to 6 months after injury (p=.87, p=.39 and p=.14, respectively, mixed-effect models). Meanwhile, the mean angular change of fractured vertebrae was 4.3° / 3.2° initially and 1.2° / 2.5° at 6 months (the brace group / no-brace group, respectively; p=.007, mixed-effect models). A significant difference was also observed between the rigid brace group and the no-brace group (p=.008, mixed effect models). The incidence of secondary vertebral fractures was 1.6% / 11.4% at 1 month, indicating a significant difference (the brace group / no-brace group, respectively; p=.028). The hazard ratio for the cumulative incidence of secondary fractures due to orthotic treatment was 0.47 (95% confidence interval 0.20–1.09, p=.054). CONCLUSIONSAlthough orthotic treatment for fresh OVF did not relieve pain, it might contribute to the stabilization of the fractured vertebra, especially using a rigid brace. Moreover, it might influence a reduction of the imminent vertebral fracture risk immediately after the onset of OVF. ClassificationsClinical study

Early Balloon Kyphoplasty Treatment for Osteoporotic Vertebral Fracture Reduces Adjacent Vertebral Fractures.

Background and Objectives: This study retrospectively examined whether the incidence rates of adjacent vertebral fractures (AVFs) can be reduced through balloon kyphoplasty (BKP) for osteoporotic vertebral fractures (OVFs) in the early stages, when there is little vertebral height variation. Materials and Methods: A total of 95 patients (22 males, 73 females, mean age: 80.7 years) who had undergone BKP were divided into two groups: the Early group (underwent BKP within 2 weeks after injury, n = 62), and the Non-early group (underwent BKP > 2 weeks after injury, n = 33). The following data were analyzed: patient characteristics; fracture level; the presence of old vertebral fractures, posterior wall injury, and intravertebral cleft; duration of surgery; duration of hospitalization; cement volume; the occurrence of AVF; the timing of AVF occurrence; Numerical Rating Scale (NRS) scores at the preoperative, postoperative, and final follow-up assessments; posterior vertebral kyphosis angle of the affected vertebra on plain lateral X-ray; vertebral wedge ratio; local kyphotic angle; and changes in posterior vertebral kyphosis angle, vertebral wedge ratio, and local kyphotic angle between preoperative and postoperative assessments. The patients were divided based on the occurrence or non-occurrence of AVF after BKP: the Non-AVF group, in which AVF did not occur, and the AVF group, in which AVF occurred. Results: The incidence of AVF was 15.8% (15/95 patients), with a notably lower incidence rate in the Early group at 6.5% (4/62 patients) compared to the Non-early group at 33.3% (11/33 patients). NRS scores significantly improved in both groups at the postoperative assessment and final follow-up. The changes in posterior vertebral kyphosis angle and vertebral wedge ratio were significantly lower in the Early group. In the Non-AVF group, the time from injury to surgery was significantly shorter. Conclusions: The Early group had a significantly lower incidence of AVF. The time from injury to surgery was a risk factor for AVF occurrence, suggesting that early BKP is recommended.

Conservative fracture treatment in old people

The numbers of osteoporotic fractures will increase due to the demographic change, which particularly affects the proximal femur, pelvis, proximal humerus, wrist and vertebral column. Surgical treatment is superior to conservative treatment of proximal femoral fractures. Non-dislocated fractures of the wrist can also be treated with a plaster cast but studies suggest that the results in the first 12months are better after surgical treatment. The situation is similar for fractures of the proximal humerus and non-dislocated fractures in particular can also be treated conservatively. Ascore and classification were recently developed for making decisions on the treatment of osteoporotic vertebral fractures. Fractures of the anterior and posterior pelvic ring can be treated conservatively with the patient under sufficient analgesia as long as there is no substantial dislocation. The highest priority in geriatric traumatology is fast remobilization.

Posterolateral Instrumented Fusion in Elderly Patients With a Single Osteoporotic Vertebral Fracture: Evaluation of Health-Related Quality of Life.

Introduction Treatment of osteoporotic vertebral fractures (OVFs) is a factor that affects the quality of life and should be considered during management. In patients with a single OVF and neurologic deficit, surgical procedures aiming at neural decompression with instrumented fusion should be considered in elderly individuals. Posterolateral instrumented fusion (PLF) constitutes a largely performed fusion surgery for patients featuring indications for fusionsurgery. The aim of this study was to determine the safety, effectiveness, and impact on health-related quality of life (HRQoL) of PLF surgery in elderly patients diagnosed with a single OVF. Methods This study was conducted at Interbalkan European Medical Center, Thessaloniki, Greece. Eighty (80) consecutive individuals with OVFs were subjected to PLF and recruited in this prospectively designed non-randomized study. Clinical evaluation was performed preoperatively and postoperatively at particular chronic intervals at one, three, six, and 12 months and two years. The assessment was conducted via the standardized Visual Analogue Scale (VAS) and Short-Form 36 (SF-36) Medical Health Survey Questionnaire for pain and HRQoL, respectively. Results No major perioperative complications were observed. All parameters of SF-36 presented significant improvement over the entire follow-up period with VAS scores reaching a plateau at six months. Depicted improvement of these parameters proves the beneficial role of PLF in elderly patients who suffered from a single OVF with or without referable neurological deficit. Conclusion OVFs have a significant impact on the quality of life of elderly patients, and surgical treatment with PLF with or without decompression can lead to functional recovery, pain relief, and HRQoL amelioration. Our results demonstrated that the outcomes of PLF in the surgical treatment of these patients are remarkably favorable, demonstrating the safety and efficacy of the technique.

Osteoporotic vertebral fractures of the thoracic and lumbar spine

The frequency of osteoporotic vertebral fractures in the clinical routine is increasing due to the demographic change. They are the most frequent fractures associated with osteoporosis and affect an especially morbid and vulnerable group of patients. These fractures often occur after minor trauma or spontaneously. Pain is the predominant symptom, whereas mechanical stability is mostly sufficient, in comparison to vertebral fractures after high-energy trauma, and is not a predominant indication for surgery. These fractures can be described using the classification for fractures associated with osteoporosis and the corresponding treatment recommendations are guided by them. Besides the specific treatment of osteoporotic vertebral fractures, a holistic treatment of patients taking pre-existing comorbidities into consideration is decisive. A mobilization as quickly as possible and treatment of the underlying osteoporosis are important to prevent further fractures.

Treatment for Osteoporotic Vertebral Fracture - A Short Review of Orthosis and Percutaneous Vertebroplasty and Balloon Kyphoplasty.

The management of osteoporotic vertebral fractures (OVFs) in the elderly includes nonoperative treatment and vertebroplasty, but has not been established due to the diversity of patient backgrounds. The purpose of this study was to compare the impact of 3 treatment modalities for the management of OVF: orthotic treatment, percutaneous vertebroplasty (PVP), and balloon kyphoplasty (BKP). The method was based on an analysis of the latest RCTs, meta-analyses, and systematic reviews on these topics. No study showed a benefit of bracing with high level of evidence. Trials were found that showed comparable outcomes without orthotic treatment. Only 1 randomized controlled trial (RCT) showed an improvement in pain relief up to 6 months compared with no orthosis. Rigid and nonrigid orthoses were equally effective. Four of 5 RCTs comparing vertebroplasty and sham surgery were equally effective, and one RCT showed superior pain relief with vertebroplasty within 3 weeks of onset. In open trials comparing vertebroplasty with nonoperative management, vertebroplasty was superior. PVP and BKP were comparable in terms of pain relief, improvement in quality of life, and adjacent vertebral fractures. BKP does not affect global sagittal alignment, although BKP may restore vertebral body height. An RCT was published showing that PVP was effective in chronic cases without pain relief. Vertebroplasty improved life expectancy by 22% at 10 years. The superiority of orthotic therapy for OVF was seen only in short-term pain relief. Soft orthoses proved to be a viable alternative to rigid orthoses. Vertebroplasty within 3 weeks may be useful. There is no significant difference in clinical efficacy between PVP and BKP. Vertebroplasty improves life expectancy.

Mortality among older adults with osteoporotic vertebral fracture.

In previous observational studies, kyphoplasty for treatment of osteoporotic vertebral fractures has been associated with decreased mortality compared to conservative management. The purpose of this research was to determine whether older adults who received kyphoplasty had reduced risk of mortality compared to matched patients who did not. Retrospective cohort study of US Medicare enrollees with osteoporotic vertebral fractures between 2017-2019 comparing patients who underwent kyphoplasty to those who did not. We identified 2 control groups a priori: 1) non-augmented patients who met inclusion criteria (group 1); 2) propensity-matched patients on demographic and clinical variables (group 2). We then identified additional control groups using matching for medical complications (group 3) and age + comorbidities (group 4). We calculated hazard ratios (HRs) and 95% confidence intervals (95% CIs) associated with mortality. A total of 235,317 patients (mean (± standard deviation) age 81.1 ± 8.3years; 85.8% female) were analyzed. In the primary analyses, those who received kyphoplasty were at reduced risk of death compared to those who did not: adjusted HR (95% CI) in group 1 = 0.84 (0.82, 0.87); and in group 2 = 0.88 (0.85, 0.91). However, in post hoc analyses, patients who received kyphoplasty were at increased risk of death: adjusted HR (95% CI) in group 3 = 1.32 (1.25, 1.41) and 1.81 (1.58, 2.09) in group 4. An apparent benefit of kyphoplasty on mortality among patients with vertebral fractures was not present after rigorous propensity matching, illustrating the importance of comparing similar individuals when evaluating observational data.

New Insights in the Pathophysiology, Epidemiology, and Response to Treatment of Osteoporotic Vertebral Fractures.

Vertebral fractures (VFs) make up an important but challenging group of fractures often caused by osteoporosis. Osteoporotic fractures pose unique diagnostic challenges in generally requiring imaging for diagnosis. The objective of this narrative mini-review is to provide an overview of these recent advances in our knowledge of VF pathophysiology and epidemiology with particular focus on endocrine diseases, prevention, and treatment. We searched PubMed on May 23, 2022, for studies of VFs in humans. Results were limited to papers available as full-text publications in English, published from 2020 and onward. This yielded 3457 citations. This was supplemented by earlier publications selected to add context to the recent findings. Studies addressed VF risk in hyperthyreosis, hyperparathyroidism, acromegaly, Cushing syndrome, primary aldosteronism, and diabetes. For pharmaceutical treatment, new studies or analyses were identified for romosozumab and for weekly teriparatide. Several studies, including studies in the immediate pipeline, were intervention studies with vertebroplasty or kyphoplasty, including combination with stem cells or pharmaceuticals. Endocrinologists should be aware of the high likelihood of osteoporotic VFs in patients with endocrine diseases. Though licensed treatments are able to substantially reduce the occurrence of VFs in patients with osteoporosis, the vast majority of recent or ongoing randomized controlled trials in the VF area focus on advanced invasive therapy of the fracture itself.

Porous titanium microsphere kyphoplasty for augmentation treatment of osteoporotic vertebral fractures: Technical report and case series.

Vertebral augmentation procedures (VAPs) are used in cases of persistent and unresponsive pain in patients with vertebral compression fractures (VCFs). Although VAPs are considered a safe procedure providing quick pain relief and improved physical function, some postoperative complications can occur, for example, bone cement leakage. The material used in this procedure is almost exclusively polymethyl methacrylate (PMMA), which appears to lack biological activity and osteointegration capabilities. In this study, we introduce a new filling system consisting of cannulas preloaded with titanium microspheres, which stabilizes and consolidates the structure of the vertebral body in treating VCFs after the performance of the kyphoplasty procedure. We report a retrospective case series of six patients affected by osteoporotic vertebral fractures with worsening back pain, neurologic impairment, and failed conservative treatment who underwent the VAP at our institute, for which the SPHEROPLAST [MT ORTHO s.r.l., Aci Sant'Antonio (CT), Italy] system was used. The patients had failed an average conservative trial of 3.9 weeks before they presented to us with neurodeficit. There were two men and four women with a mean age of 74.5 years. The average hospital stay was 2 days. There were no reported perioperative complications related to cement injection, such as intraoperative hypoxia, hypotension, pulmonary embolization, myocardial infarction, neurovascular or viscera injury, or death. The VAS score significantly decreased from a mean preoperative of 7.5 (range 6-19) to 3.8 (range 3-5) immediately after surgery and 1.8 (range 1-3). We report the first clinical results in a series of six patients treated for VCF using the microsphere system after analyzing the clinical results produced by, and the complications that arose from, this new device. In patients with VCF, the VAP using titanium microspheres appears to be a feasible and safe procedure with a low risk of material leakage.

Balloon Kyphoplasty in the Treatment of Osteoporotic Vertebral Fractures with Lumbar Radiculopathy

Balloon Kyphoplasty in the Treatment of Osteoporotic Vertebral Fractures with Lumbar Radiculopathy

Stent-armed kyphoplasty in osteoporotic thoracolumbar fractures-clinical and functional results and a center experience over 10 years.

The optimal treatment of osteoporotic vertebral fractures is still a controversial and under discussion topic. Armed kyphoplasty with expansive intravertebral implants is an emerging procedure, which, in theory, it not only makes it possible to achieve instant analgesia, and to get stabilization gains of benefits of kyphoplasty and vertebroplasty, but also, allows for a more effective maintenance of the restored vertebral height. A retrospective observational study is presented, in which 30 patients participated, including a total of 33 osteoporotic thoracolumbar compression burst vertebral fractures with involvement of one or both vertebral platforms and of more than one fifth of the posterior wall. These individuals underwent armed kyphoplasty with VBS® stents (or stentoplasty) filled with bone cement over 10 years (between 2012 and 2022) at the same center. Clinical (visual analogue scale, Oswestry Disability Index and Patient Global Impression of Change) and imaging results (restoration and maintenance of vertebral body heights) achieved were investigated. The mean follow-up time was 4.5 years (range, 1-10 years). There was a statistically significant improvement in all clinical and functional parameters evaluated, as well as a statistically significant difference in the various vertebral body heights between preoperative and end of follow-up time [increase of 10.7-15.2-5.0 mm (anterior-median-posterior) in the sagittal plane and 6.7-11.6-9.7 mm (right-median-left) in the coronal plane]. There was a statistically significant direct correlation between vertebral heights in the coronal plane, and between the Beck index assessed at the end of the follow-up period and the improvement in functional disability. The percutaneous transpedicular posterior approach, the ability to anatomically restore the fractured vertebra and to maintain it in the medium-long term, as well as the reduced risk of adverse effects, make stent-armed kyphoplasty a very attractive treatment option for osteoporotic compressive thoracolumbar fractures. A clinical-morphological correlation was demonstrated regarding the surgical treatment of these fractures, it was found that a more effective morphological restoration of vertebral heights in both the sagittal and coronal planes is associated with superior satisfactory clinical functional parameters.

Is vertebral stenting kyphoplasty a good choice in the treatment of osteoporotic vertebral fracture? A series of 47 patients (v2).

The incidence of vertebral fragility fracture is increasing over last three decades with an essential impact on quality of life. Some devices were proposed to improve conventional kyphoplasty in the last five years, known as vertebral stenting kyphoplasty (VSK). All osteoporotic vertebral fractures (OVF) treated with VSK, single-level fracture without neurological impairment, and with more than 24 months of follow-up were included in the study. We recorded fracture types according to DGOU classification, fracture level, regional kyphosis angle (RKA), Oswestry disability index (ODI), and complications. Forty-seven consecutive patients were included. RKA significantly improved from pre to postoperative values (p<0.000001) and to follow-up values (p<0.00001). A significant difference was found between preoperative RKA of (OF2+OF3) and OF4 (p<0.00001), confirmed immediately after surgery (p= 0.005425) and at last follow up (p= 0.000947). A significant difference was found in correction of RKA between (OF2+OF3) and OF4 at injury time and after treatment (p<0.00001), and it was confirmed at the last follow-up (p=0.000026). ODI showed a significant difference between (OF2+OF3) and OF4 type of fractures (p=0.038216). We recorded five complications: 2 cases of leakage without neurological impairment, two progressions of kyphosis, and one implant migration. VSK is an excellent and reliable option in the treatment of OVF, with good clinical results and preservation of obtained RKA at the time of treatment. However, in case of vertebral collapse with the involvement of both vertebral plates, surgeons must be aware of possible implant failure or migration. 4.

Compliance with wearing a thoracolumbar orthosis in nonoperative treatment of osteoporotic vertebral fractures: a prospective sensor-controlled study

BACKGROUND CONTEXTHyperextension orthoses (HOs) for nonoperative treatment of osteoporotic vertebral fractures (OVFs) are widely prescribed. However, the compliance, how much an HO is worn after it has been prescribed, is widely unknown. PURPOSEThis study was performed to assess the wearing time of HOs for OVFs in a prospective blinded, sensor-controlled manner. STUDY DESIGN / SETTINGA prospective, single blinded observational study was performed. PATIENT SAMPLEThis study prospectively included 18 patients who were treated nonoperatively with an HO for OVFs. OUTCOME MEASURESThe true wearing time was measured using a hidden temperature-based sensor. The patients were invited to return for regular follow-up every 2 weeks for 6 weeks, at which time clinical evaluation (including a visual analog scale for pain and the Oswestry disability questionnaire) and radiographs of the spine were performed. METHODSFull compliance was defined as a wearing time of 15 hours per day. Correlation between compliance and demographic differences, patient reported outcomes and radiographic changes of the vertebral structures were calculated. RESULTSThe mean HO wearing time was 5.5±3.3 hours (37%±22% compliance). Female patients used the HO significantly longer per day than did male patients (6.5±3.2 vs 2.9±2.0 hours, p=.039). Age and body mass index had no influence on wearing behavior. CONCLUSIONSOverall, compliance with wearing HOs is poor and shows great variability with significant gender-dependency but not associated with BMI, age, or pain-level. Further studies are required to confirm our results that the wearing time does not have an influence on kyphotic progression of the osteoporotic fractured segment, nor on clinical outcome at short term. LEVEL OF EVIDENCEI

Three generations of treatments for osteoporotic vertebral fractures: what is the evidence?

The management of vertebral compression fractures (VCFs) is based on conservative treatment and minimally invasive vertebral augmentation procedures. However, the role of vertebral augmentation is now being questioned by clinical trials and extensive studies. The aim of this review is to report the most relevant evidences on effectiveness, safety, and indications of the currently available vertebral augmentation techniques. Conservative treatment with bracing is effective in reducing acute but it has no effect on segmental kyphosis progression and pseudoarthrosis can occur. Percutaneous vertebroplasty (PV) was the first vertebral augmentation technique to be proposed for the treatment of VCFs. Two blinded and randomized clinical trials compared PV to a sham procedure and no significant differences in terms of efficacy were reported. More recent studies have suggested that PV can still benefit patients with acute VCFs and severe pain at onset. Balloon kyphoplasty (BK) was developed to improve the segmental alignment restoring the height of collapsed vertebrae. BK allows similar pain relief and disability improvement, as well as greater kyphosis correction compared to PV, moreover BKP seems to reduce cement leakage. Vertebral body stenting (VBS) and the KIVA system are third generation techniques of vertebral augmentation. VBS aims to increase the effectiveness in restoring the segmental alignment, while the KIVA system can prevent cement leakage. These techniques are effective and safe, even if their superiority to BK has yet to be proven by studies with a high level of evidence.

Study on the influence of balloon dilation mode on the intravertebral cleft of osteoporotic fracture

BackgroundIntravertebral cleft is common in osteoporotic vertebral compression fracture, and the bone sclerosis around the fissure brings difficulties to the surgical treatment. It is not known whether the balloon dilatation mode of percutaneous kyphoplasty affects the distribution of bone cement in the fracture vertebral body and further affects the surgical effect. The purpose of this study was to discuss the effect of balloon dilatation mode on percutaneous kyphoplasty in the treatment of osteoporotic vertebral fractures with intravertebral cleft.MethodsAccording to the inclusion criteria and exclusion criteria, a retrospective analysis of patients with osteoporotic vertebral fracture combined with intravertebral cleft treated by percutaneous kyphoplasty in our hospital was conducted. All patients were divided into two groups based on way of balloon dilation. The mode of balloon dilatation, imaging changes of vertebral body, VAS score, ODI score, bone cement distribution and postoperative complications were analyzed.ResultsA total of 96 patients with osteoporotic vertebral fracture combined with intravertebral cleft were included in the study, including 51 patients treated with single balloon bilateral alternating dilatation technique and 45 patients treated with double balloon bilateral dilatation technique. The vertebral height, Cobb’s angle of kyphosis, VAS score and ODI score were significantly improved in both groups after operation (P < 0.05). The postoperative vertebral height and Cobb’s angle of kyphosis in the double balloon bilateral dilatation group were better than those in single balloon bilateral alternating dilatation group (P < 0.05). The distribution of bone cement in the single balloon bilateral alternating dilatation group was more inclined to insert filling, while the double balloon bilateral dilatation group was more inclined to fissure filling. The VAS score and ODI score at the final follow-up in the single balloon bilateral alternating dilatation group were lower than those in the double balloon bilateral dilatation group (P < 0.05).ConclusionDouble balloon bilateral dilatation technique can better restore the injured vertebral height in patients with osteoporotic vertebral fracture combined with intravertebral cleft. However, the distribution of injured vertebral cement in patients with single balloon bilateral alternating dilatation technique is more likely to be inserted and filled, and the long-term analgesia and lumbar function of patients are better.

Osteoporotic vertebral fractures-From diagnosis to treatment

The aim of the present work is an overview of current concepts in the treatment of osteoporotic vertebral fractures, risk factors, clinical presentation and conservative and operative management. Osteoporotic vertebral fractures are awidespread problem, affecting between 700,000 and 1.5million adults annually in the USA alone. Osteoporotic vertebral fractures can cause severe physical impairment, including back pain, dysfunction, and progressive thoracic kyphosis. Mortality after osteoporotic vertebral fractures is still increased compared to age-matched controls. In the reality of care, advocates of purely conservative therapy as well as advocates of surgical treatment can be found all over the world. In summary, understanding the risk factors, appropriate clinical evaluation and treatment strategies are crucial. When surgery is indicated, balloon kyphoplasty shows significantly better pain reduction and lower mortality compared to nonsurgical treatment.

Absolute Bed Rest Duration of 3 Days for Osteoporotic Vertebral Fractures: A Retrospective Study.

Retrospective case-control study. To reduce unnecessary absolute bed rest (ABR), this study sought to determine the optimal aimed length of ABR in older patients getting conservative treatment for osteoporotic vertebral fractures (OVFs). OVFs are quite common in elderly patients. ABR is a vital part of conservative treatment for OVFs, although the length of ABR may increase patient. No recommendations regarding how long ABR should last. This study was conducted in 134 patients with OVFs initially treated conservatively. The patients were split into two groups: 3-day and 7-day ABR. From the time of injury to 1, 4, and 12 weeks after injury, compression rate (CR) and local kyphotic angle (LKA) were assessed and compared between the two groups. Any complications such as pneumonia, deep vein thrombosis, delirium, and urinary tract infection known to be related to ABR were examined based on the electronic medical record. Forty-four patients underwent ABR for 3 days and 90 underwent ABR for 7 days. There was no significant difference in CR and LKA between the two groups at the time of injury versus 1, 4, and 12 weeks after injury. The patients were divided into two groups: those who received a 3-day ABR and those who received a 7-day ABR. CR and LKA were measured and compared between the two groups from the time of damage to 1, 4, and 12 weeks after injury. The ABR-related complication rate was 43.4% in the 7-day ABR group and 22.7% in 3-day ABR group (p=0.02). The duration of hospital stay was significantly shorter in the 3-day ABR group (12.8 days) than in the 7-day group (16 days) (p=0.01). Considering radiological outcomes, prognosis, complications, patient convenience, and economic impact, a 3-day ABR period is appropriate for the conservative treatment of OVFs.

Effect of Different Anesthesia and Puncture Methods of Percutaneous Kyphoplasty on More Than 90-Year-Old Osteoporotic Vertebral Fracture: Advantages of the ERAS Concept.

Background Percutaneous kyphoplasty (PKP) is an effective minimally invasive technique for the treatment of osteoporotic vertebral fracture (OVF) in recent years. This study focuses on the analysis of PKP surgery and anesthesia in osteoporotic vertebral facture patients over 90 years old with the concept of “enhanced recovery after surgery.” Methods This study reviewed 239 patients who were diagnosed with OVF retrospectively between October 2015 and June 2019. According to the method of anesthesia, these patients were divided into Group A (n = 125) and Group B (n = 114). According to the pedicle puncture approach, these patients were divided into Group C (n = 102) and Group D (n = 137). The anterior vertebral height (AVH) and local kyphosis angle (LKA) were used to evaluate the degree of vertebral damage and restoration. The visual analogue scale (VAS) and the Oswestry Disability Index (ODI) scores were used for assessing functional outcomes. Some parameters were used to assess the perioperative conditions such as operation time, amount of bone cement perfusion, intraoperative fluoroscopy times, anesthesia recovery time, time out of the bed, hospital stay, hospitalization cost, and complications. Results The visual analogue scale (VAS), Oswestry Disability Index (ODI), anterior vertebral height (AVH), and local kyphosis angle (LKA) 1 day, 1 year after surgery, and at the last follow-up all showed significant improvement (P < 0.05) in comparison with those before surgery both in Groups A and B and Groups C and D. The ODI 1 day after surgery was significantly better in Group B than Group A (P < 0.05). Compared with Group B, Group A required longer time of anesthesia, operation time, anesthesia recovery time, time to get out of bed, and length of hospital stay and more hospitalization costs (P < 0.05). Group D required longer operation time, longer time to get out of bed, more bone cement volume, fluoroscopy time, and more operation hospitalization costs compared with Group C (P < 0.05). Conclusion We recommend unilateral puncture under local anesthesia for OVF in the patients aged over 90 from the perspective of rapid recovery.

Occurrence of adjacent segment fractures after surgical treatment of an osteoporotic vertebral fracture: a retrospective comparison between two different treatment methods

IntroductionOsteoporotic vertebral fractures are a major healthcare problem. Vertebral cement augmentation (VCA) is frequently used as a minimally invasive surgical approach to manage symptomatic fractures. However, there is a potential risk of adjacent segment fracture (ASF), which may require second surgery. The addition of transcutaneous screw-fixation with cement augmentation superior and inferior to the fracture [Hybrid transcutaneous screw fixation (HTSF)] might represent an alternative treatment option to reduce the incidence of ASF.Materials and methodsWe retrospectively compared surgery time, hospital stay, intraoperative complication rate and the occurrence of ASF with the need for a surgical treatment in a cohort of 165 consecutive patients receiving either VCA or HTSF in our academic neurosurgical department from 2012 to 2020. The median follow-up was 52.3 weeks in the VCA-group and 51.9 in the HTSF-group.ResultsDuring the study period, 93 patients underwent VCA, and 72 had HTSF. Of all patients, 113 were females (64 VCA; 49 HTSF) and 52 were males (29 VCA; 23 HTSF). The median age was 77 years in both groups. Median surgery time was 32 min in the VCA-group and 81 min in the HTSF-group (p < 0.0001). No surgery-related complications occurred in the VCA-group with two in the HTSF-group (p = 0.19). ASF was significantly higher in the VCA-group compared to HTSF (24 [26%] vs. 8 [11%] patients; p < 0.02). The proportion of patients requiring additional surgery due to ASF was higher in the VCA-group (13 vs. 6%), but this difference was not statistically significant (p = 0.18). Median hospital stay was 9 days in the VCA-group and 11.5 days in the HTSF-group (p = 0.0001).ConclusionsBased on this single-center cohort study, HTSF appears to be a safe and effective option for the treatment of osteoporotic vertebral compression fractures. Surgical time and duration of hospital stay were longer in the HTSF-group, but the rate of ASF was significantly reduced with this approach. Further studies are required to ascertain whether HTSF results in superior long-term outcomes or improved quality of life.
