Medium-term results of percutaneous vertebroplasty in multiple myeloma.

Vertebral compression fractures (VCFs) are common in multiple myeloma (MM). Percutaneous vertebroplasty (PVP) is used to stabilize vertebral collapse and treat the pain. Few studies have been carried out on PVP in MM and follow-up has tended to be short. We have prospectively evaluated the safety and efficacy of PVP in the VCFs resulting from MM or plasmacytomas. Nineteen PVP were performed in 12 consecutive patients. We monitored their pain and functional status using visual analog (VAS) and Eastern Cooperative Oncology Group (ECOG) scale, respectively. For a subjective assessment, every patient was asked about his/her degree of satisfaction. The mean age of the participants was 66 yr. Significant improvement occurred 1 d after PVP according to the VAS score (7.5 pre-PVP to 3.7, P < 0.0001) and ECOG assessment (3.1 to 2.5, P = 0.002). This significant improvement was maintained after 3.2 yr of follow-up. Sixty-three percent of patients were highly satisfied with the result of the PVP and 37% were satisfied. The peri-operative mortality was 0%. Leakage of the cement outside of the vertebral body was noted in 16 of 19 injected vertebrae (84%) but none of the patients developed any clinical or neurological symptoms. At the last follow-up, no further collapse in the treated or neighboring vertebrae was noted. VCFs caused by MM or plasmacytomas can be effectively treated by vertebroplasty. PVP is associated with early clinical improvement of pain and function and can be maintained after a long follow-up without major procedure-related complications.

Can burst fractures be predicted from plain radiographs?

Plain radiographs of 67 acute spinal compression fractures in 49 patients were analysed by subjective and objective criteria, using CT scans as the diagnostic standard for the diagnosis of burst fracture. Discriminant analysis correctly predicted the type of fracture in 88% of cases. Burst fractures, however, were almost as frequently misdiagnosed as being wedge compression fractures using this technique, compared with the reading of 25 films from patients without previous information. A quarter of the injuries would have been misdiagnosed had reliance been placed solely on the plain radiographs. CT scans of all patients with acute spinal compression fractures should be considered to decrease this potentially serious diagnostic error.

[Sudden blindness following operative care of a multiply traumatized patient: posterior ischemic optic neuropathy].

A 32-year-old man had fallen from an 8-m high scaffolding and had suffered multiple traumatic injuries, such as compression fractures of the thoracic vertebrae (TV) 5-7 without incarceration of the spinal canal plus a distal femoral fracture. During surgery on the day of the accident, spondylodesis and dorsal stabilization of TV 4-7 using an internal fixator were carried out and the distal femoral fracture was stabilized with a dynamic condylar screw (DCS). On the day following the accident, the malposition of a pedicle screw located at the height of TV 4 and the borderline malposition of a pedicle screw of TV 7 were corrected. Between the day of the accident and day 8 after, the patient developed impaired vision and in the further course amaurosis associated with fixed pupils. No organopathy could be noticed which could have explained the sudden vision loss. A study of the literature was done, using the keywords "blindness" and "spine surgery." Only very few cases describing a connection of spine surgery and postoperative vision loss could be found. This article aims to elaborate on the few connections worked out in these investigations.

[Treatment of unstable thoracic and lumbar spinal fractures with Cotrel-Dubousset instruments].

The present study is a retrospective analysis of first experiences of fracture treatment with the Cotrel-Dubousset instrumentation technique. Thirty-five unstable spine fractures were treated with the CD implant at the University of Louisville--Level I Trauma Center--between June, 1985 and August, 1987. There were 17 burst fractures, 12 compression fractures and 2 fracture dislocations, 2 flexion distraction fractures and 2 flexion rotation injuries. Twenty patients underwent anterior cord decompression and strut grafting followed by posterior CD instrumentation and posterolateral fusion. Fifteen patients had posterior CD instrumentation and fusion alone. No neurological deterioration after the procedure was observed, 5 patients improved neurologically. In eleven cases bracing after the operation was unnecessary. Hospital stay varied between 6 and 35 days (mean 20 days). Follow-up ranged from 12 to 30 months, mean follow-up was 19 months. The loss of correction in the sagittal plane varied between 0 and 20 degrees (mean 5.6) at final follow-up. Complications due to the implant have not been observed except an avulsion of an upper thoracic hook, which did not effect the clinical or radiographic result. The high stability of the implant provides a decreased risk of neurological deterioration, posttraumatic kyphosis as well as early rehabilitation.

Unipedicle percutaneous vertebroplasty for spinal intraosseous vacuum cleft.

UNLABELLED: Osteoporotic compression fractures have been widely treated by vertebroplasty through a bipedicle approach. We suspected that a compression fracture with vacuum cleft can be treated successfully with a unipedicle approach. We retrospectively reviewed 27 patients with an osteoporotic compression fracture with intraosseous vacuum cleft. The patients received percutaneous vertebroplasty with bone cement (polymethylmethacrylate) augmentation. Bone cement was injected into the fractured vertebral body through only one cannula in the selected pedicle. Cement filling, vertebral height restoration, and relief of pain were evaluated. The minimum followup was 12 months (range, 12-30 months). Twenty six of 27 patients had adequate filling. Average vertebral height restoration was 27%. The patients' visual analog scale improved an average of 40 points. Percutaneous transpedicle vertebroplasty is effective for treating osteoporotic compression fractures with intraosseous vacuum clefts. Because of the preexistent cleft, the procedure can be done successfully via a unipedicle approach. LEVEL OF EVIDENCE: Therapeutic study, Level IV (case series--no, or historical, control group). See the Guidelines for Authors for a complete description of levels of evidence.

Treatment of painful compression vertebral fractures with vertebroplasty: results and complications.

AIM: The aim of this paper is to assess the effectiveness and safety of percutaneous vertebroplasty in patients with focal pain caused by compression vertebral body fractures. MATERIALS AND METHODS: Over an eleven-month period 49 patients underwent percutaneous vertebroplasty, of which seven were retreated, for a total of 56 operations on 108 vertebrae. The patients were affected by osteoporotic compression fractures (n=28) or by benign and malignant infiltrative processes (n=21). All of the patients were examined at discharge and later at one week, and one, three, six and nine months after surgery to ascertain the development of the pain and possible changes in the quality of life. The mean length of follow-up was 3.8 months. RESULTS: One week after treatment all patients reported complete disappearance or significant alleviation of the pain. In 8 out of 49 patients (16.3%) there was a reoccurrence of pain; 7 of these patients underwent further treatment at another level with immediate pain relief. After surgery only three patients (6.1%) continued to take non-steroidal anti-inflammatory drugs (NSAIDs), whereas prior to surgery all patients were taking pain medication. We also observed an important benefit in the quality of life, in that after treatment all patients reported an improvement in functional abilities, and only three (6.1%) still had to wear a back brace (against 15 in the preoperative period). We only had one serious complication (1.7%) which involved the formation of a subcutaneous paravertebral haematoma, which was resolved in about a week. Eight patients (16.3%) developed transient pain at the site of the puncture or radiculopathy in the days following the operation. In 63 out of 108 of the treated vertebrae (58) there were small asymptomatic leakages of cement outside the vertebral body and in two asymptomatic patients (3.5%) the chest radiograph revealed a small pulmonary embolism of cement. DISCUSSION: Our experience confirms the effectiveness of vertebroplasty in the treatment of pain caused by vertebral fractures. If the indications are respected the improvement of symptoms is often immediate, such as the return of mobility, and patient satisfaction with surgery is higher. The use of appropriate guiding systems limits the number of complications.

[Chronic recurrent multifocal osteomyelitis].

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare, inflammatory, skeletal disease of unknown origin, which mainly affects children and adolescents in terms of cleido-spondylo-metaphysal skeletal inflammation. Only 10% of the patients are older than 20 years. To date, only about 200 cases have been reported in the literature. In the course of the disease, the initial radiological signs are osteolysis followed by sclerosis and hyperostosis in the end stage. The histological investigations reveal chronic inflammatory infiltrates with lymphocytes and hyperostosis. Although the prognosis of CRMO, to our current understanding, is self limiting, serious complications have been reported such as pathological fractures and compression fractures of the spine. A recently recommended therapy scheme is based on the administration of azithromycin combined with calcitonin. We present the case of a 25 year old female patient who has suffered from CRMO for 1.5 years with the cervical spine and the manubrium sterni being affected. The current state of diagnosis, therapy, and prognostic outlook of this rare disease are discussed.

Another option to treat Kümmell's disease with cord compression.

The efficiency of short-segment fixation with transpedicle body augmenter (a titanium spacer with bone-ingrowth porous surface, TpBA) to treat Kümmell's disease with cord compression (stage III) was retrospectively evaluated. No laminectomy or instrumentation reduction was done. Inclusion criteria included Frankel CDE, single-level within T10-L2. FU rate was 88%, i.e. 21 cases were included. Frankel function classification was 6E9D6C. Mean age was 72+/-8 years. F:M was 16:5. FU period was 48 M (range, 30-76 M). The hospitalization was 4.5+/-2.2 days; operation time, 70.4+/-17.2 min; blood loss, 150+/-72 cc. Final Frankel class was 20E1D. Complications included two superficial infection and one pneumonia. Body height and kyphosis were all corrected significantly and well preserved at the final visit. No TpBA dislodgement or implant failure was noted; however, three cases developed new compression fractures. The clinical outcome showed 81% with P1 or P2 by Denis pain scale. This method can decompress spinal canal, maintain kyphosis correction and vertebral restoration, prevent implant failure, and attain good clinical results.

A case of systemic lupus erythematosus expressing intractable thrombocytopenia remedied effectively by intermittent and continuous administrations of a small amount of immune globulin.

We describe a case where intermittent and continuous administrations of a small amount of immune globulin were effective in the treatment of refractory chronic immune thrombocytopenic purpura by systemic lupus erythematosus (SLE). Steroid pulse therapy and cyclophosphamide pulse therapy were considered for thrombopenia. However, the patient had compressed fracture of the lumbar vertebrae due to osteoporosis and right external malleolus ulcer with complications of infection. Therefore, high-dose intravenous immune globulin (IVIG) therapy (400 mg/kg daily for 5 consecutive days) was administered. Then, as a maintenance therapy, a small amount of 400 mg/kg for 1 day (400 mg/kg monthly) was given in an intermittent and continuous manner, which resulted in improvement of thrombocytopenia and reduction of the amount of steroid administered.

Breast adenocarcinoma metastatic to epidural cervical spine meningioma: case report and review of the literature.

While several cases of cancer metastatic to cranial meningiomas have been reported, metastasis to spinal meningioma has been reported only once, and a mechanism for such metastases has not been investigated. We report a case of breast carcinoma metastatic to an epidural cervical meningioma, summarize the literature on metastases to central nervous system meningiomas, and suggest a possible mechanism. Our patient, a 55-year-old woman, presented with difficulty walking, back pain, and quadriparesis. Magnetic resonance imaging revealed an enhancing C3-4 epidural lesion and an L4 compression fracture. Because of concern that the fracture and epidural lesion might represent metastases, we performed a metastatic work-up, which revealed a right breast mass. The patient underwent C3-C4 laminectomies and an epidural lesion was encountered. Intraoperative frozen section revealed mixed meningioma and breast adenocarcinoma. A gross total resection was achieved and the patient subsequently received spinal irradiation and hormonal therapy. Whereas a literature review revealed numerous reports of metastases to cranial meningiomas, this represents only the second reported case of such pathology in the spine. Mechanisms of this unusual process likely include meningiomas' vascularity, meningiomas' slow growth providing nutrient availability, and perhaps, as suggested by our analysis, E-cadherin expression by both meningiomas and breast cancer. Metastasis to meningioma must be considered in an epidural spinal lesion in all patients with a known malignancy, with surgical aggressiveness tailored to the intraoperative pathologic diagnosis.

Delayed traumatic thoracic spinal epidural hematoma: a case report and literature review.

Spinal epidural hematoma is a relatively uncommon disease, but an important cause leading to cord compression. Posttraumatic spinal epidural hematoma is a rare entity and remains a challenge for clinical physicians. Magnetic resonance imaging is the best choice for early diagnosis, and urgent surgical decompression with evacuation of hematoma could improve some neurologic deficits, especially vital cord functions. We presented a 77-year-old woman who sustained back pain after a fall 1 month before admission, complaining of progressive weakness and sensory loss in bilateral lower extremities since 2 weeks before admission. Radiography of the thoracic spine revealed decreased body height at T10 and compression fracture. Magnetic resonance imaging of the thoracic spine revealed epidural hematomas at the level of T11 to T12. An urgent decompressive laminectomy with evacuation of hematoma was performed immediately. Postoperatively, her previous neurologic deficits improved except for an underactive neurogenic bladder and fecal incontinence.

Burst fracture of the first lumbar vertebra and conus-cauda syndrome complicating a single convulsive seizure: a challenge of diagnosis in the Emergency Department.

Fractures of the thoracic and lumbar vertebrae as a direct consequence of generalized epileptic convulsions are the most common non-traumatic type of fracture complicating epileptic seizures. The majority of these fractures are compression fractures that occur with minimal symptoms and virtually no permanent neurological sequela. Nevertheless, muscle contractions generated during generalized motor seizures can result in severe axial skeletal trauma and grave neurological complications. We describe the case of a 35-year-old man who suffered a burst fracture of the first lumbar vertebral body and acute conus medullaris-cauda equina syndrome as a direct consequence of a single grand mal seizure. The aim of this report is to draw attention to this serious complication of generalized convulsive seizures and alert readers to epilepsy-related vertebral fractures. Diagnosis and management of acute cauda equina-conus medullaris syndrome caused by lumbar fracture are reviewed.

[Ankylosed spine fractures with spondylitis or diffuse idiopathic skeletal hyperostosis: diagnosis and complications].

PURPOSE OF THE STUDY: Spinal fractures in patients with ankylosing spondylitis or idiopathic skeletal hyperostosis can raise difficult diagnostic and therapeutic problems. Spinal fracture is well known in ankylosing spondylitis but exceptional in diffuse idiopathic skeletal hyperostosis. The purpose of the present work was to identify clinical and radiological features in patients with ankylosing spondylitis, to determine whether similar risks and clinical expression are observed in patients with diffuse idiopathic skeletal hyperostosis, and to present a radiological classification of these fractures. We did not assess therapeutic methods in the present study. MATERIAL AND METHODS: Forty-eight fractures in 48 patients were observed over a period of 17 years. Twenty patients (mean age 62 years) had ankylosing spondylitis and 28 patients (mean age 81 years) had diffuse idiopathic skeletal hyperostosis. A fall was the immediate cause of the fracture in more than half of the patients. No notion of trauma could be identified in six patients. The radiological classification was established as follows; type I open-wedge anterior fracture, type II "sawtooth" fracture, type III occult or radiologically invisible fracture, type IV non-specific fractures comparable to other spinal fractures. A computed tomography was obtained in all patients seen after 1992 and magnetic resonance imaging was performed in case of suspected extradural hematoma. The ASIA classification (as modified by Frankel) was used for cord injuries. Clinical course and complications were noted. RESULTS: Diagnosis was established the day of fracture in 32 patients (12 spondylitis and 20 hyperostosis) and between day 2 and 30 for 16 (8 spondylitis and 8 diffuse idiopathic skeletal hyperostosis). The radiological classification was: type I n=30, type II n=4, type III n=8, type IV n=6 (one odontoid fracture, five compression fractures). Three patients had extradural hematomas (2 spondylitis and 1 hyperostosis). Thirty-four patients (11 spondylitis and 23 hyperostosis) had cord injuries, including 16 with a symptom-free interval. The ASIA classification was: type A n=4, type B n=6, type C n=20, type D n=4. Thirty-two patients died within the first three months after spinal fracture (10 spondylitis and 22 hyperostosis), due to bed rest related complications in 30. One patient died after rupture of an aortic aneurysm. DISCUSSION: Spinal fractures in patients with ankylosing spondylitis or diffuse idiopathic skeletal hyperostosis generally occur spontaneously or after low-energy trauma. Subsequent complications have serious consequences. Late diagnosis either results from missing a radiologically visible fracture or from the presence of an occult "paper thin" fracture. We do not have experience with diagnostic scintigraphy or magnetic resonance imaging. In our opinion, repeating standard x-rays the second and third weeks and use of a spiral scan or multiple spiral scan could provide early diagnosis. CONCLUSION: The possible diagnosis of spinal fracture should be explored very extensively in patients with a symptomatic ankylosed spine who present symptoms compatible with spinal fracture, with or without trauma.

Bilateral symmetric polyarthralgia revealing Fanconi's syndrome.

We report the case of a 45-year-old woman who presented with a six-year history of diffuse polyarthralgia responsible for major disability. She reported bilateral symmetric arthralgia in nearly every joint, as well as back pain. Muscle wasting predominating in the roots of the limbs was found. Laboratory tests showed hypocalcemia, severe hypophosphatemia, hypokalemia, alkaline phosphatase elevation, aminoaciduria, and hyperphosphaturia, with no glycosuria. Radiographs disclosed osteolysis of the pubic symphysis, multiple pelvic fractures, vertebral compression fractures, and diffuse demineralization. A bone scan visualized symmetric foci of hyperactivity in nearly all joints and fracture sites. Dramatic improvements in clinical and radiographic abnormalities were noted after six months of treatment with phosphate and calcitriol. This is a case of incomplete Fanconi syndrome, with no glycosuria. The clinical presentation of Fanconi syndrome can be misleading. Fanconi syndrome should be borne in mind as a possible cause of polyarthralgia to avoid diagnostic delay, which in our patient led to a picture of pseudomyopathy with multiple fractures.

Clinical review of the early stability of spine injuries.

One hundred fifteen cervical fractures, 51 thoracic and lumbar major fractures, 214 compression fractures, and 34 transverse process fractures from Los Angeles County-University of Southern California Medical Center and Rancho Los Amigos Hospital were reviewed. Epidemiology, fracture type, and early results of treatment in terms of musculoskeletal and neurologic stability were studied. Flexion-rotation fractures of the cervical, thoracic, and lumbar spine showed significant loss of reduction when not treated with operative internal fixation. Operative intervention did not influence the neurologic outcome. Laminectomy resulted in progressive deformity and a significantly increased incidence of second operations. Epidemiology indicated changing patterns of fracture.

Diagnosis of subtle thoracolumbar burst fractures. A new radiographic sign.

A previously undescribed radiographic sign, the posterior vertebral body angle is successful in distinguishing subtle burst type fractures from compression fractures of the thoracolumbar spine. Correct diagnosis is imperative for proper treatment and accurate prognosis. When positive, this sign will alert the orthopaedist so that further diagnostic testing with computed tomography or sagittal tomograms may be performed. The sensitivity of this sign in diagnosing subtle burst type injuries is 75%.

Primary leiomyosarcoma of the vertebra: Case report and review of the literature.

A case of primary leiomyosarcoma of a thoracic vertebra associated with a compression fracture in a 75-year-old woman was preoperatively thought to be granulation tissue. Surgical decompression was performed and the histological and immunohistochemical studies established the diagnosis of leiomyosarcoma. Based on the clinical and radiological examinations, metastases were ruled out. Primary leiomyosarcoma of the vertebra is extremely rare and in that site it is considered to have a relatively poor prognosis.

Percutaneous vertebroplasty: relationship between vertebral body bone marrow edema pattern on MR images and initial clinical response.

PURPOSE: To prospectively investigate the relationship between initial clinical response and bone marrow edema pattern on preprocedural magnetic resonance (MR) images in vertebral bodies selected for percutaneous vertebroplasty (PVP). MATERIALS AND METHODS: Institutional review board approval and written informed consent were obtained. PVP was performed for osteoporotic compression fractures in 80 consecutive patients (mean age, 72.4 years; range, 44-85 years; 67 women and 14 men; 157 vertebrae). Patients were divided into three groups according to the proportion of the vertebra in which the bone marrow edema pattern was observed on sagittal MR images: group 1, 50% or more of the vertebra; group 2, less than 50%; group 3, no edema pattern observed. By using Wilcoxon rank sum test, Fisher exact test, and Wilcoxon signed rank test, groups were examined for differences in treatment efficacy, which was defined as the difference between preprocedural and postprocedural pain as assessed by means of visual analog scale (VAS) score at 1-3 days after PVP. RESULTS: Forty-four patients were assigned to group 1, 14 to group 2, and 22 to group 3. No significant difference was seen between the groups with respect to age, sex, number of treated vertebrae, or preprocedural VAS score. In group 1, VAS score decreased from 7.5 before the procedure to 2.9 after (improvement of 4.6). In group 2, the score decreased from 6.8 to 3.1 (improvement of 3.7). In group 3, the score decreased from 7.0 to 4.3 (improvement of 2.7). Improvement was significantly greater in group 1 than in group 3 (P < .005). CONCLUSION: PVP resulted in significantly greater clinical improvement in patients with an extensive bone marrow edema pattern than in those without this pattern. (c) RSNA, 2006.
