Pain response in the first trimester after percutaneous vertebroplasty in patients with osteoporotic vertebral compression fractures with or without bone marrow edema.

BACKGROUND AND PURPOSE: Presence of bone marrow edema (BME) in osteoporotic vertebral compression fractures (VCF) detected by MR imaging as selection criterion for percutaneous vertebroplasty (PV) is speculative. To clarify significance of BME in VCF, we assessed pain response after PV in patients with VCF with full BME versus patients with VCF with absent BME. METHODS: From a cohort of patients with painful VCF selected for PV, pain response in 14 patients with absent BME in VCF was prospectively compared with pain response in 31 patients with full BME in VCF. Pain was evaluated before PV and at 1 and 3 months after PV with visual analog scores and analgesics used. Back pain in general and at treated vertebral levels was assessed. RESULTS: Pain decrease after PV at treated levels was observed in 10 (71%) patients with absent BME in VCF at both follow-up periods and in 29 (94%) patients with full BME 1 month after PV and 30 (97%) at 3 months after PV. Differences between the groups were significant (P = .04 at 1 month; P = .01 at 3 months). Pain response was not affected by other patient or imaging characteristics. General back pain after PV was comparable in both groups after PV (P = .08 at 1 month; P = .4 at 3 months). CONCLUSION: Pain decrease after PV in patients with VCF is more frequently observed when full BME is present. Because 71% of patients with VCF with absent BME responded favorably on pain, PV should not be withheld based on absence of BME alone.

[The study of treatment of osteoporotic thoracolumbar multi-vertebral compressive fractures by kyphoplasty with one balloon].

OBJECTIVE: To evaluate the effect of kyphoplasty in treating osteoporotic thoracolumbar multi-vertebral compressive fractures with one balloon. METHODS: thirteen cases (37 vertebral bodies) of osteoporotic thoracolumbar multi-vertebral compressive fractures were treated. The patients were women, range 65 to 79 years old, and all with well intact posterior wall of vertebral body. 37 thoracolumbar vertebral bodies were treated by Kyphoplasty with one balloon under "C" armed imaging guiding. RESULTS: All 13 patients tolerated well. The mean height of the anterior, media and posterior vertebral bodies was (1.9 +/- 0.5) cm, (1.5 +/- 0.5) cm, (2.6 +/- 0.5) cm preoperatively and (2.1 +/- 0.4) cm, (2.2 +/- 0.4) cm, (2.8 +/- 0.5) cm postoperatively (P < 0.001). The mean kyphosis was improved from (31.3 +/- 14.1) degrees to (24.8 +/- 11.3) degrees. There was not back pain and deformed correction was maintained well after 17.3 months' follow up, No complication occurred. CONCLUSION: The balloon was not damaged, because the pressure was lower than usual pressure, the cost of patients was saved. In this study, we fulfilled small amount of cement in vertebral body which reduced the leakage of cement. Fracture of close vertebral body was also reduced because of lower stiffness and modulus of elasticity of adjacent vertebral body.

Comparison of therapeutic effect between percutaneous kyphoplasty and pedicle screw system on vertebral compression fracture.

OBJECTIVE: To compare the clinical efficacy of percutaneous kyphoplasty (PKP) with pedicle screw system (PS) in the treatment of vertebral compression fracture(VCF). METHODS: Eighty-six patients with VCF were treated either by PKP (Group A, n equal to 30) or PS (Group B, n equal to 56). The anterior, intermediate, and posterior heights of the vertebrae body, visual analogue pain scale (VAS) before and after operation, the duration of operation, and amount of blood loss between two groups were compared. RESULTS: No statistical difference was noted regarding the vertebral height between two groups. Significant difference was seen in VAS, duration of operation and amount of blood loss between the two groups (P less than 0.01). CONCLUSIONS: Percutaneous kyphoplasty has the similar therapeutic efficacy with pedicle screw system in treatment of VCF with a minimal invasion, less operation time and blood loss. For those with posterior wall destruction, PS is deemed favorable.

Combined percutaneous transpedicular tumor debulking and kyphoplasty for pathological compression fractures. Technical note.

Percutaneous balloon kyphoplasty has become a widely adopted treatment option for patients with pain due to pathological compression fractures. One potential risk of the procedure is the displacement of tumor into the spinal canal and resulting spinal cord or cauda equina injury during inflation of the balloon prior to polymethylmethacrylate (PMMA) placement. In addition, the presence of any remaining tumor between the PMMA and the fractured cortical bone can lead to suboptimal improvement in stabilization and subsequent pain relief. The authors describe a technique to remove tumor from within the vertebral body (VB) through a percutaneous working channel prior to kyphoplasty balloon inflation and augmentation. The technique was successfully used in all three patients who had presented with pain, and the pain improved in all three cases. There was no extravasation of PMMA into the spinal canal in any case. A combined VB tumor debulking and kyphoplasty technique offers the ability to improve the placement of PMMA within the diseased vertebral body, potentially leading to increased safety as well as clinical effectiveness for stabilization of these fractures.

[Treatment of severe vertebral compressive fractures in the elderly with percutaneous vertebroplasty].

OBJECTIVE: To evaluate the efficacy of treating severe and chronic vertebral compressive fractures in the elderly with percutaneous vertebroplasty. METHODS: Sixteen patients who suffered from severe back pain and whose daily living was badly affected were retrospectively reviewed. The average age was 72.5 years, the average disease history was 19 months, and the average compressive rate of the affected vertebral bodies was 74.1%. RESULTS: Nineteen affected compressive vertebral bodies in 16 cases were treated with percutaneous vertebroplasty. All the procedures were successful without any complication. After 3.5-7 ml of cement was injected into the lesions, complete relief was achieved in 3 cases, remarkable relief was achieved in 11 cases, and improvement was observed in 2 cases. The scores of 6-point Behavioral Rating Scale and Activity of Daily Living (ADL) declined significantly after the treatment (P < 0.001). CONCLUSION: Percutaneous vertebroplasty can significantly improve the symptoms and quality of life in the elderly patients with severe and chronic vertebral compressive fractures.

Prospective clinical follow-up after percutaneous vertebroplasty in patients with painful osteoporotic vertebral compression fractures.

PURPOSE: To prospectively assess short-term, midterm, and long-term pain relief in patients with painful osteoporotic vertebral compression fractures (VCFs) treated with percutaneous vertebroplasty (PV). MATERIALS AND METHODS: Visual analog scale (VAS) scores for pain at the treated vertebral level, analgesic use, and satisfaction with outcome were assessed in 112 patients after PV of 168 VCFs. Serial follow-up was performed at 24 hours and 3, 6, and 12 months and in a small number of patients at 1-3 years. Procedure-related complications were evaluated by physical examination and computed tomography of treated levels. RESULTS: After PV, VAS scores for pain at the individual vertebral levels treated and use of analgesic agents were significantly reduced compared with before treatment at every follow-up period. Within 24 hours after the procedure, the decreases in all scores were less compared with scores at later follow-up periods, but this was not significant. The preprocedural mean VAS score was 8.8 (range, 5-10). At follow-up, mean VAS scores ranged from 2.5 to 3.3 (range, 0-10). In the short term after PV, patients used significantly less analgesic drugs and 86% of patients were satisfied with the outcome. At midterm and long-term follow-up, patients used even less analgesic drugs and 95%-100% of patients were satisfied with the outcome of PV. Procedure-related complications with clinical consequences occurred in three patients (2.7%): one patient experienced a cardiovascular reaction, one patient had a pedicle chip fracture, and one had a rib fracture. CONCLUSION: PV of painful osteoporotic VCFs provides significant pain reduction in nearly all treated patients.

The utility of in-phase/opposed-phase imaging in differentiating malignancy from acute benign compression fractures of the spine.

BACKGROUND AND PURPOSE: Benign and malignant fractures of the spine may have similar signal intensity characteristics on conventional MR imaging sequences. This study assesses whether in-phase/opposed-phase imaging of the spine can differentiate these 2 entities. METHODS: Twenty-five consecutive patients who were evaluated for suspected malignancy (lymphoma [4 patients], breast cancer [3], multiple myeloma [2], melanoma [2], prostate [2], and renal cell carcinoma [1]) or for trauma to the thoracic or lumbar spine were entered into this study. An 18-month clinical follow-up was performed. Patients underwent standard MR imaging with an additional sagittal in-phase (repetition time [TR], 90-185; echo time [TE], 2.4 or 6.5; flip angle, 90 degrees ) and opposed-phase gradient recalled-echo sequence (TR, 90-185, TE, 4.6-4.7, flip angle, 90 degrees ). Areas that were of abnormal signal intensity on the T1 and T2 sequences were identified on the in-phase/opposed-phase sequences. An elliptical region of interest measurement of the signal intensity was made on the abnormal region on the in-phase as well as on the opposed-phase images. A computation of the signal intensity ratio (SIR) in the abnormal marrow on the opposed-phase to signal intensity measured on the in-phase images was made. RESULTS: Twenty-one patients had 49 vertebral lesions, consisting of 20 malignant and 29 benign fractures. There was a significant difference (P < .001, Student t test) in the mean SIR for the benign lesions (mean, 0.58; SD, 0.02) compared with the malignant lesions (mean, 0.98; SD, 0.095). If a SIR of 0.80 as a cutoff is chosen, with >0.8 defined as malignant and <0.8 defined as a benign result, in-phase/opposed-phase imaging correctly identified 19 of 20 malignant lesions and 26 of 29 benign lesions (sensitivity, 0.95; specificity, 0.89). CONCLUSION: There is significant difference in signal intensity between benign compression fractures and malignancy on in-phase/opposed-phase MR imaging.

Kyphoplasty for vertebral compression fractures: 1-year clinical outcomes from a prospective study.

OBJECT: Over the past 15 years, vertebroplasty has emerged as a treatment for vertebral compression fractures. This technique, however, does not restore vertebral height and is associated with a high rate of cement leakage. Recently, kyphoplasty was developed in an effort to circumvent this problem. Although its immediate results have been reported, it is unclear whether the benefits endure. METHODS: Seventy-eight consecutive patients underwent 188 kyphoplasty procedures. The patients responded to Short Form-36 (SF-36) questionnaires, a visual analog scale (VAS) for pain rating, and the Oswestry disability index (ODI) instrument; additionally they underwent detailed neurological and radiographic examinations pre- and postoperatively. The preoperative SF-36, VAS, and ODI scores, the neurological examination results, and the radiographic data were compared with the postoperative findings. Thirteen patients died of disease progression or unrelated illness. Of the surviving patients, complete data were available in 62% (minimum follow-up period 12 months, mean 18 months). Complications included one myocardial infarction and five cases of asymptomatic cement extravasation. No case of neurological deterioration occurred during the follow-up period. Significant improvements in seven measures of the SF-36 inventory as well as on the ODI and VAS were noted early postoperatively, and these persisted throughout the follow-up period, despite a statistically insignificant decline in the measure of general health at last follow-up examination. CONCLUSIONS: Kyphoplasty is an effective treatment for vertebral compression fractures. The benefits presented in the early postoperative period and persisted at 1 year posttreatment.

L5 vertebral compression fracture: a series of five cases.

OBJECTIVE: The purpose of this paper is to discuss five cases of L5 vertebral compression fracture (VCF), illustrating the epidemiology, clinical presentation and radiographic appearance of the fracture at this uncommon site. Additionally, an empirical approach to conservative management of L5 VCFs is also discussed. DESIGN: A series of five cases. SETTING: Private chiropractic clinic. CONCLUSIONS: Compression fractures at the L5 level are rare; however, this problem should be considered in postmenopausal women who suffer from low back pain and in young men with a history of trauma. Conservative treatment options, including both passive therapy and exercise, can be beneficial in the management of this condition.

Fatal fat embolism syndrome after numerous vertebral body compression fractures in a lung transplant recipient.

The fat embolism syndrome is an uncommon clinical disorder that typically occurs as a complication of severe trauma. We report the case of a 60-year-old single-lung transplant recipient who died of massive fat emboli. Before lung transplantation, the patient had been treated with corticosteroids for at least 1 year because of chronic obstructive pulmonary disease caused by centrilobular emphysema and asthmatic bronchitis. After receiving his lung transplant, he was treated with triple-drug immunosuppression, which included 25 mg of prednisone per day. He was discharged from the hospital 2 months after transplantation only to be readmitted 2 weeks later with cytomegalovirus pneumonia, from which he recovered. Concomitantly, he had new lumbar compression fractures with severe back pain and lost approximately 3 cm in height during a 3-week period. On the eleventh day after hospital readmission, he suddenly had a "sepsis-like" illness without a known infectious cause, numerous petechiae and ecchymoses, marked pulmonary edema with worsening diffuse pulmonary infiltrates, profound hypoxemia, decreased mentation, and mild thrombocytopenia. He died 3 days later. With the exception of a positive sputum culture for cytomegalovirus, all cultures were negative. The postmortem examination showed severe osteoporosis, multiple vertebral compression fractures, and widespread massive fat emboli. This is the first reported case of fat emboli as the cause of death in a lung transplant recipient, and the case suggests that the fat embolism syndrome should be considered in the differential diagnosis of a sepsis-like illness in patients who have received steroids during a long period, particularly in the setting of vertebral compression fractures.

Calcium phosphate cement-based vertebroplasty compared with conservative treatment for osteoporotic compression fractures: a matched case-control study.

OBJECT: Few studies have been conducted to compare vertebroplasty and conservative treatment for osteoporotic vertebral compression fractures (OVCFs). To investigate the effects of calcium phosphate cement (CPC)-based vertebroplasty on relief of pain and augmentation of the fractured vertebral body (VB), the authors compared the results of CPC-assisted vertebroplasty with those of conservative treatment alone. METHODS: Two groups of patients were examined: the vertebroplasty group (30 consecutive patients with primary OVCF) and the control group (30 patients matched for age, sex, interval from injury to treatment, and grade of the posterior wall defects of the fractured VB). Outcome measures included the visual analog scale (VAS) score of back pain and analgesic requirements, and the radiographically documented rate of the VB kyphosis. The follow-up duration was more than 12 months (mean 17 months). The mean VAS score at 12 months after injury was 0.67 cm in the vertebroplasty group and 1.97 cm in the control group, and the mean improvement rates in the VAS scores were 91.6 and 73.6%, respectively (p < 0.0001). The mean duration of analgesic requirement was 8.3 days in the vertebroplasty group and 62.2 days in the control group (p = 0.0005). The mean kyphosis rate at 12 months after injury was 72.9% in the vertebroplasty group and 58% in the control group, and the mean recovery rate of kyphosis was +8.4 and -21%, respectively (p < 0.0001). CONCLUSIONS: The authors conclude that CPC-assisted vertebroplasty provides better clinical and radiological results than conservative treatment for primary OVCF.

Efficacy and safety of balloon kyphoplasty in the treatment of vertebral compression fractures: a systematic review.

The aim of this study is to evaluate the efficacy and safety of balloon kyphoplasty (BK) in the management of vertebral compression fractures (VCFs). This study is based on a systematic review of the literature (until October 2004) and meta-analysis of clinical studies assessing the efficacy and safety of BK in the treatment of VCFs. Estimates of effect were based on a random effects model. Meta-regression analyses were carried out where required. A total of 26 studies met the inclusion criteria. Although studies displayed considerable methodological limitations, the results of the clinical series indicate significant improvements in pain intensity, vertebral height, sagittal alignment, functional capacity, and quality of life. Compared with conventional medical management, BK afforded significant improvement in pain intensity and mobility. Likewise, a significant reduction was observed in vertebral collapse, kyphotic deformity, the development of new vertebral fractures, and hospital stay. Compared with vertebroplasty, the technique reduced the loss of height and the degree of kyphotic deformity, and afforded a significantly lower leakage rate-with no differences in relation to other variables. Regarding adverse effects, leakage affected 7% of all levels treated, while complications were recorded in 2% of the patients, and new vertebral fractures in 16%. The available evidence suggests that BK can be effective and safe in application to VCFs. However, existing studies evince substantial methodological limitations and relatively short follow-up periods. Better clinical research is required to determine the capacity of BK to avoid the functional and physiological sequelae of VCFs and to define the true role of the technique among the existing therapeutic options.

Spinal compression fractures in osteoporotic women: patterns and relationship to hyperkyphosis.

A prospective study of thoracic and lumbar spinal fracture distribution and its relationship to thoracic kyphosis was performed in 87 women with osteoporosis. Anterior wedge fractures were most commonly seen in the midthoracic spine and about the thoracolumbar junction, whereas central compression fractures were most common from the first to the fourth lumbar levels. Solitary wedge fractures did not occur above the seventh thoracic vertebra, suggesting that a cause other than osteoporosis must be suspected in any patient with an isolated high thoracic fracture. Analysis of the spinal radiographs obtained in an additional 16 women without osteoporosis revealed that both forms of fracture were unusual in this small group with normal spinal mineralization. The number of anterior wedge fractures in the thoracic spine correlated (r = .546) with the degree of thoracic kyphosis. However, 19% of the women with no thoracic fractures still had thoracic hyperkyphosis. The authors conclude that the hyperkyphosis of osteoporotic women is related to anterior compression fractures but also has contributing nonskeletal factors.

Primary leiomyosarcoma of the cervical spine causing spontaneous compression fracture: report of an autopsy case.

An extremely rare case of the primary leiomyosarcoma of the cervical spine presenting as a compression fracture is reported. A 69-year-old man complained of dysesthesia of both hands. A plain radiograph, computed tomography and magnetic resonance imaging of the cervical spine showed a compression fracture of the vertebral body at C7 without the formation of an obvious mass. From radiological findings, the fracture was considered to be caused by an infiltrative vertebral bone tumor. Biopsy of the tumor revealed a leiomyosarcoma, a metastatic tumor being ruled out by a systemic investigation. The patient died of pleural metastasis 6 months later, and an autopsy confirmed the primary site of the tumor as the cervical spine.

[Balloon-assisted percutaneous vertebroplasty in patients with osteoporotic vertebral body compression fractures--first results].

PURPOSE: To determine the feasibility, efficacy and safety of balloon-assisted percutaneous vertebroplasty (BA-VP) in patients with osteoporotic vertebral compression fractures (VCFs). MATERIALS AND METHODS: In 47 patients (29 women, 18 men; mean age: 70 years and 4 months) with severe VCFs, 66 BA-VPs were performed via a unipedicular access. After initial puncture (under combined fluoroscopy and CT guidance) of the vertebral body (VB), the needle was retraced by 1.5 cm, and a 12-mm Fogarty balloon catheter was introduced and inflated using 2-4 ml diluted contrast media (CM). After the subsequent removal of the catheter and repositioning of the needle, vertebroplasty was performed. RESULTS: The mean volume of PMMA injected was 4.4 ml (2.5-7.2 ml). Pain reduction (measured by the Visual Analogue Scale) was achieved in 95 % of the patients, dropping from on average 8.0 pre-intervention to 2.2 after a mean follow-up of 8 months. A reduction of the pain relieving medication was achieved in 68 % of the cases and patient activity improved markedly. No severe or clinically relevant complications were observed. Cement leakage occurred by filling of epidural and paravertebral veins in 9.1 and 6.1 % of the cases, respectively. Leakage into the paravertebral soft tissues was seen in 3.0 % of the patients and to the adjacent disc space in 10.6 % of the cases. CONCLUSION: Vertebroplasty and kyphoplasty are currently used to treat osteoporotic VCFs but show either a comparatively high leakage rate or are rather complex and expensive. Balloon-assisted vertebroplasty seems to combine advantages from both methods and is effective, safe and comparatively inexpensive.

Bone marrow edema in osteoporotic vertebral compression fractures after percutaneous vertebroplasty and relation with clinical outcome.

BACKGROUND AND PURPOSE: Little is known about the evolution of bone marrow edema (BME) in osteoporotic vertebral compression fractures (VCF) after percutaneous vertebroplasty (PV) or about its relation with relief of pain. In this study, we prospectively assessed changes in BME with MR imaging at 3, 6, and 12 months after PV and related changes in BME with pain evolution and analgesic use over time. METHODS: BME percentage was assessed in 64 patients after PV of 89 VCF with serial MR imaging follow-up at 3, 6, and 12 months. Pain was assessed before PV and at every follow-up interval by visual analog scale for pain and type of analgesic used. Relation between changes in BME and pain evolution was assessed in a subgroup of 31 patients with a single treated VCF and neither new VCF at follow-up nor pain at another untreated level. RESULTS: BME gradually decreased over time. At 1 year after PV, 29% of treated VCF still demonstrated BME. Once BME disappeared, it did not return. Pain relief was most striking the first 3 months after PV and remained constant thereafter. There was no relation between relief of pain and extent, presence, or absence of BME after PV. CONCLUSION: A gradual decrease of BME in osteoporotic VCF treated with PV is apparent during 12 months of MR imaging follow-up. Decrease of BME is unrelated to relief of pain.

Iatrogenic vertebral body compression fracture in a premature infant caused by extreme flexion during positioning for a lumbar puncture.

We present a case of vertebral body compression fracture that resulted from manual flexion of the spine of a premature infant in preparation for a lumbar puncture. Vertebral body fractures due to abnormal flexion in child abuse have been described. However, such fractures due to lumbar puncture-related positioning have not been reported. We present a pre-term infant who developed an L3 vertebral body compression fracture immediately after lumbar puncture.
