Percutaneous vertebroplasty for symptomatic osteoporotic vertebral compression fracture adjacent to lumbar instrumented circumferential fusion

The purpose of this study was to evaluate the efficacy and safety of percutaneous vertebroplasty for patients with symptomatic osteoporotic vertebral compression fractures adjacent to lumbar instrumented circumferential fusion. Between January 2005 and June 2010, eighteen patients in the authors' institution with lumbar instrumented circumferential fusion had adjacent symptomatic osteoporotic vertebral compression fractures. The patients received percutaneous vertebroplasty using polymethylmethacrylate bone cement augmentation. Radiographs and magnetic resonance imaging were used. The visual analog pain scale and modified Brodsky's criteria were used to compare clinical outcomes pre- and postoperatively. Minimum follow-up was 18 months. Dual-energy x-ray absorptiometry scan confirmed osteoporosis in all patients. The average interval between fusion surgery and sustaining osteoporotic vertebral compression fractures was 24.8 months. The average interval between sustaining osteoporotic vertebral compression fractures and undergoing percutaneous vertebroplasty was 49.3 days. One-level percutaneous vertebroplasty was performed in 13 patients, and 2 levels were performed in 5 patients. The patients' visual analog pain scale scores improved by an average of 53 points postoperatively. Fifteen patients returned to preinjury activities of daily living. The average restoration of the fractured vertebral body height was 12.1%. No major surgery-related complications, occurred except asymptomatic cement leakage in 3 patients. Elderly patients undergoing lumbar instrumented fusion surgery should be aware of the possibility of adjacent vertebral compression fractures. Percutaneous vertebroplasty is a minimally invasive and effective procedure to treat such adjacent segment disease.     

Treatment of pain from osteoporotic vertebral collapse by percutaneous PMMA vertebroplasty

Summary Background. Vertebral compression fractures are common complications in advanced osteoporosis. In general, this disease of the elderly patient is characterized by severe local back pain. Pathophysiologically, bony instability triggers local pain during body movement. Serious pain immobilizes the patients and forces them to bed rest. As a result, complications like thrombosis or pneumonia occur. Invasive treatment with surgical instrumentation for vertebral stabilization is not indicated in elderly patients especially with additional diseases.The purpose of this study was to test the hypothesis that percutaneous polymethylmethacrylate (PMMA) vertebroplasty significantly reduces pain due to vertebral collapse in osteoporotic patients and improves quality of life.Methods. A total of 38 patients with osteoporotic vertebral compression fractures of the thoracic and lumbar spine were treated by PMMA vertebroplasty. After admission, before discharge from the hospital, six weeks, half a year and one year later patients answered the Oswestry Low Back Pain Disability (OLBPD) Questionnaire for assessment of treatment related change in disability. In all patients percutaneous vertebroplasty was performed under local anesthesia.Findings. A total of 92% of patients reported a significant pain reduction immediately after treatment. Also one year after vertebroplasty pain remained significantly reduced. Vertebroplasty was highly beneficial for patients with pain related to local instability of the spine. Extravasation of PMMA beyond the vertebral margins was observed in 26% of the cases. No treatment related clinical or neurological complications were noticed.Interpretation. PMMA vertebroplasty is a useful and safe method of pain relief which rapidly regains quality of life for patients with osteoporotic vertebral compression.

Vertebroplasty: benefits are more than risks in selected and evidence-based informed patients. A retrospective study of 59 cases

Vertebral compression fractures represent a frequent pathology among elderly population, with potentially devastating consequences. More than 20 years have passed since percutaneous vertebroplasty was initially used in the treatment of angiomas, representing nowadays a widely used treatment for osteoporotic vertebral fractures. The authors present a retrospective review of 59 consecutive patients (in total 94 fractured levels) that underwent polymethylmethacrylate percutaneous vertebroplasty for vertebral compression fractures due to senile or secondary osteoporosis. All fractures were free from neurologic involvement and were classified as A1 type according to Magerl classification. All of patients were initially treated conservatively, by application of orthosis that allows immediate deambulation. At control, patients who complained of pain and limitation of daily activities underwent MRI. If presence of marrow signal changes, especially hypertense signal in T2-weighted images was confirmed, percutaneous vertebroplasty procedure was performed (we could call it “sub-acute” procedure). A limited group of patients that did not tolerate brace and had an insufficient pain control underwent vertebroplasty “in acute”, few days after fracture. Immediate post-operative pain reduction and follow-up clinical outcome (estimating quality of life and residual back pain) were evaluated by means of Visual Analogue Scale, SF-36 and Oswestry Disability Index. In the immediate post-operative course a significant pain relief was found in 39 patients (66.1%), moderate pain relief in 17 (28.8%), while 3 (5.1%) did not achieve relevant pain improvement. Pain intensity and life quality was maintained within satisfactory limits after a mean follow-up of 16 months. In conclusion, percutaneous vertebroplasty is an effective and safe procedure for treating vertebral compression fractures in the elderly. It provides immediate pain relief and allows early mobilization, thus avoiding potentially severe complications related to persistent back pain and prolonged bed rest. When performed by experienced surgeon complication rate is low, representing a safe procedure, able to provide a satisfactory outcome.     

Modified unilateral transpedicular percutaneous vertebroplasty for treatment of osteoporotic vertebral compression fractures

Objective: To comparatively assess the clinical outcome of modified unilateral percutaneous vertebroplasty for the treatment of osteoporotic vertebral compression fractures. Methods: The clinical outcome and incidence of cement extrusion in a consecutive group of 70 patients at our institution between December 2005 and December 2008 was retrospectively reviewed. Thirty‐five patients were randomly distributed to modified percutaneous vertebroplasty (Group A) and 35 to traditional percutaneous vertebroplasty (Group B). A visual analog scale (VAS) was used on the first post‐operative day and 1 year later to assess the severity of pain before and after vertebroplasty. The incidence of cement extrusion on CT scan was also compared between the two groups. Results: The treatment was successful in all seventy patients. The incidence of cement extrusion was 14.29% (5/35 patients) in group A, and 37.12% (13/35 patients) in group B, this difference being statistically significant (P < 0.05). No patients had serious complications. Complete pain relief was achieved in 50 patients, and significant relief in the other 20 (20/70 patients). There was no statistically significant difference between Groups A and B. Conclusion: Modified percutaneous vertebroplasty enhances the accuracy of cement injection into the center of the vertebral body, increasing the safety of the procedure with no increase in cost. It is a safer and more easily performed technique for treating patients with osteoporotic vertebral compression fractures than traditional percutaneous vertebroplasty.

Percutaneous vertebroplasty for pain relief and spinal stabilization

STUDY DESIGN: This was a retrospective review of 47 consecutive patients (1995-1998) in whom percutaneous intraosseous methylmethacrylate cement injection (percutaneous vertebroplasty) was used to treat osteoporotic vertebral compression fractures and spinal column neoplasms. OBJECTIVES: To present initial results regarding pain relief, spinal stabilization, and complications after treatment with percutaneous vertebroplasty. SUMMARY OF BACKGROUND DATA: Percutaneous vertebroplasty was developed in France in the late 1980s. Several European reports have described excellent results for treatment of compression fractures and neoplasms. The procedure was not performed in the United States until 1994. Only a single series of 29 patients treated in the United States has been reported. METHODS: A retrospective review was conducted of 47 consecutive patients with 84 vertebrae treated with percutaneous vertebroplasty. Thirty-eight patients with 70 vertebrae had symptomatic, osteoporotic fractures and had failed medical therapy. Eight patients with 13 vertebrae had primary or metastatic neoplasms. One patient had a hemangioma. Immediate and long-term pain response, spinal stability, and complications were evaluated. RESULTS: Among the 38 patients treated for osteoporotic fractures, 24 (63%) had marked to complete pain relief, 12 (32%) moderate relief and 2 (5%) no significant change. Only 4 of the 8 patients with malignancies had significant pain relief. In 7 of these patients, no further vertebral compression occurred, and spinal canal compromise was prevented. The patient with the hemangioma had no significant pain reduction. Minor complications occurred in 3 (6%) patients. CONCLUSIONS: Percutaneous vertebroplasty provided significant pain relief in a high percentage of patients with osteoporotic fractures. The procedure provided spinal stabilization in patients with malignancies but did not produce consistent pain relief. Complications were minor and infrequent. Percutaneous vertebroplasty is a promising therapy for patients with osteoporotic fractures and for selected vertebral column neoplasms.     

Percutaneous vertebroplasty as a treatment for osteoporotic vertebral compression fractures: a systematic review

Percutaneous vertebroplasty has been performed for more than ten years to treat painful osteoporotic vertebral compression fractures. Clinical results have been encouraging, but little is known about the efficacy and safety of this minimally invasive procedure. We therefore performed a systematic review to assess the efficacy and safety of percutaneous vertebroplasty in osteoporotic vertebral compression fractures. A search was conducted using Medline, Embase and The Cochrane Controlled Trials Register. The search yielded fifteen studies, eleven prospective, three retrospective and one controlled trial. Totally 1,136 interventions were performed on 793 patients. Mean pain scores, measured using a 0 to 10 VAS score, improved significantly from 7.8 to 3.1 (−60.3%) immediately after percutaneous vertebroplasty. The short-term complication rate varied between 0.4 and 75.6%. Leakage of cement outside the vertebral body was markedly common, ranging from 3.3 to 75.6%. Although the majority was asymptomatic, a few devastating clinical adverse effects were reported (mean 2.4%). Although percutaneous vertebroplasty is a widely accepted treatment for osteoporotic vertebral fractures, we revealed only a single controlled trial. We conclude that there are insufficient data available to reliably assess efficacy of percutaneous vertebroplasty. The procedure has a low rate of clinical complications, but potential complications can be devastating. In the future, assessing the efficacy of percutaneous vertebroplasty requires controlled trials with long-term follow-up.

Percutaneous vertebroplasty for treatment of thoracolumbar spine bursting fracture

OBJECTIVE: Percutaneous vertebroplasty can be very beneficial for patients with vertebral osteoporotic compression fractures. To the best of our knowledge, however, there has been no mention in any literature regarding the use of percutaneous vertebroplasty for the treatment of spinal burst fracture. METHODS: A preliminary study was conducted on 6 patients with traumatic burst fractures of vertebrae treated with percutaneous vertebroplasty starting in June 2000. Fractures involving the anterior and middle columns of the vertebrae and the canal were mildly compressed by the retropulsed bone fragment. However, there was no obvious neurologic deficit in these patients. They initially underwent conservative treatment and thoracolumbar spinal orthosis (TLSO) brace for at least 3 months, but the intractable pain caused patients to be bedridden for prolonged periods of time and limited daily activity. As a result, the patients underwent percutaneous vertebroplasty with polymethylmethacrylate (PMMA) for treatment of spinal burst fractures. RESULTS: Six male patients (mean age: 38.2) who suffered from burst fractures of vertebrae with disabling back pain refractory to analgesic therapy and TLSO brace were treated in this study. The duration of conservation treatment period was 3.5 months to 8 months (mean: 5.2 months). There was no motility. However, 4 vertebrae (66.7%), on radiographs revealed evidence of PMMA leakage through the endplate fracture site into either the disc space or the paravertebral space, without any evident clinical symptoms. No intracanal leakage was seen, and no patient needed a secondary surgical intervention. Pain decreased from 84.3 +/- 5.4 mm at baseline to 34.7 +/- 4.4 mm at the third postoperative day, 30.2 +/- 5.8 at 3 months and 24 +/- 3.5 mm at 12 months. The reduction in pain from baseline to the 3-day and 3 month mark was statistically significant (p < 0.05). The mobility was at least 2 levels of improvement (mean improvement 2.7 points) at 12-months postoperative. CONCLUSION: In highly selective patients, percutaneous vertebroplasty can be an alternative method for the treatment of spinal burst fractures and the prevention of complications from major surgical procedures. However, this procedure still has potential risks and should be employed with extreme caution to prevent extravasation of PMMA into the spinal canal.

Percutaneous vertebroplasty for vertebral compression fracture

BACKGROUND: Percutaneous vertebroplasty has become an option for the treatment of painful osteoporotic compression fractures in patients in whom conservative medical management has failed. AIM: This paper assessed the effectiveness and safety of percutaneous vertebroplasty in patients with focal pain caused by compression vertebral body fractures. MATERIALS AND METHODS: Over a twenty-five-month period 63 patients underwent percutaneous vertebroplasty, and ten of these patients were subsequently retreated, for a total of 73 operations on 93 vertebrae. The patients were affected by osteoporotic compression fractures (n=57) or by benign or malignant infiltrative processes (n=6). All patients were examined at discharge and thereafter to assess the level of pain and investigate possible changes in the quality of life. The mean length of follow-up was 15.2 months. RESULTS: After treatment, almost 90% of patients reported complete disappearance or significant alleviation of the pain. In 7 of 63 of the patient (11%) there were small asymptomatic leakages of cement outside the vertebral body. A substantial number of patients with osteoporosis, 19% of the study population, experienced new fractures following treatment with vertebroplasty. DISCUSSION: Our experience confirms the effectiveness of vertebroplasty to pain caused by vertebral fractures. If the indications are strictly followed, improvement of symptoms is often immediate, allowing the return of mobility, and patient satisfaction with surgery is higher. The use of appropriate systems limits the number of complications.     

Percutaneous vertebroplasty in painful refractory vertebral hemangiomas

Background:

Painful vertebral hemangiomas are often inadequately managed medically. We evaluated the outcome of percutaneous vertebroplasty (PVP) in the treatment of painful vertebral hemangiomas refractory to medical management.

Materials and Methods:

14 patients (four thoracic and ten lumbar vertebra) with painful vertebral hemangiomas presenting with severe back pain for more than 6 months not responding to medical therapy were treated by vertebroplasty. Cross sectional imaging of the spine with magnetic resonance was done. Blood investigations were done to exclude coagulopathy excluded. PVP was performed under local anesthesia.

Results:

The pain intensity numeric rating scale (PI-NRS-11) of these patients was in the range of 7-10 (Severe Pain). After vertebroplasty 8 patients were completely free of pain (PI NRS Score 0) while 6 were significantly relieved (PI-NRS Score 1-3). No complications were observed. Two patients with associated radicular pain had good pain relief following PVP. No recurrence was found during 36 months of postoperative followup.

Conclusion:

PVP is a safe and effective procedure in patients with painful vertebral hemangiomas refractory to medical management.

Vertebroplasty: techniques to avoid complications.

BACKGROUND CONTEXT: The use of vertebroplasty for treatment of spinal fractures and spinal hemangiomas is increasing at a rapid pace. Although this is a minimally invasive procedure, complications have been reported. The most important of these is the unintentional migration of polymethylmethacrylate (PMMA). PURPOSE: The authors present methods, equipment, and principles that minimize occurrence of PMMA migration and other complications. STUDY DESIGN/SETTING: Patients in a private/university neurosurgery practice were studied retrospectively by chart review. PATIENT SAMPLE: During a 3-year period, 53 levels of vertebroplasty were performed on 35 patients presenting with indications of intractable pain resulting from vertebral body compression fractures. OUTCOME MEASURES: Pain assessment and outcome determination were made by the treating physician based on dialog with the patient, examination, and the patient's use of narcotics. The medical records of patients were reviewed for these factors as well as for signs of cerebrospinal fluid leak, PMMA migration, new radiculopathy, myelopathy, new fracture, pulmonary emboli, infection, or bleeding. METHODS: Criteria for inclusion consisted of disabling back pain corresponding to a recent fracture, pharmacotherapy, and medically stable for anesthesia. Vertebroplasty patients were followed up at 2 to 3 weeks and at 3 months after their procedure. RESULTS: Success rate for relief of pain was 89%. The overall complication rate was 6% per treated vertebral level. There were no deaths or delayed complications. Factors that reduce complications were identified and include the following: accurate needle placement, adequate barium radio-opacification of PMMA, viscous low pressure delivery of PMMA, and PMMA delivery under direct fluoroscopic visualization. CONCLUSION: Although vertebroplasty is considered a minimally invasive procedure, it can result in serious complications even without technical misadventures.
