[Pyogenic spondylitis after Corynebacterium striatum blood stream infection following allogeneic hematopoietic stem cell transplantation for malignant lymphoma]

Patient 1 was a 70-year-old woman with refractory diffuse large B-cell lymphoma who received allogeneic peripheral blood stem cell transplantation from an HLA-haploidentical related donor. Upper back pain appeared on day63, and Th8-Th9 pyogenic spondylitis was diagnosed based on magnetic resonance imaging (MRI). Blood culture on day14 identified Corynebacterium striatum as the causative bacteria of blood stream infection (BSI). The pyogenic spondylitis resolved after treatment with daptomycin for 2 months. Patient 2 was a 65-year-old man with relapsed angioimmunoblastic T-cell lymphoma who received bone marrow transplantation from an HLA-DR single-antigen-mismatched unrelated donor. Lower back pain appeared on day30, and L4-L5 pyogenic spondylitis was diagnosed based on MRI. Blood culture was negative. Daptomycin and clindamycin were selected for treatment based on the drug susceptibility of bacteria that had caused pre-engraftment BSI (Escherichia coli on day3 and Corynebacterium striatum on day9), and the pyogenic spondylitis resolved after 6 months of this treatment. Pyogenic spondylitis should be considered in the differential diagnosis of back pain accompanied by BSI before engraftment in allogeneic hematopoietic stem cell transplant recipients.

Pyogenic Spondylitis in Multidisciplinary Therapies of Gynecologic Malignancies: Three Cases Reports

Both during and after cancer treatment, pyogenic spondylitis is an uncommon but serious complication. Because pyogenic spondylitis is often recognized as a complication of a distant process causing bacteremia, it initially may be misdiagnosed the primary infection such as urinary tract infection. Consequently, a considerable delay in diagnosis frequently occurs. In addition, estrogen deprivation caused by cancer treatments including RT/CCRT, CT and surgical therapy promotes changes of the immune system. We report two cases of pyogenic spondylitis in a patient with vaginal cancer that occurred delay of the diagnosis, and in a patient with endometrial cancer that had chronic steroid use, and one case of suppurative osteomyelitis in a patient with vulvar cancer that had diabetes mellitus with obesity. Gynecologic oncologists must consider the diagnosis of pyogenic spondylitis based on clinical symptoms such as localized lumbago and medical history. Estrogen deprivation, repeated cancer treatment, diabetes mellitus with obesity, immunosuppression by chronic steroid use are risk factors of pyogenic spondylitis. To prevent delay in diagnosis of pyogenic spondylitis, it is necessary that we must have careful management and follow-up considering all of information such as clinical features and medical history on patients during and after treating for gynecologic malignancies.

The Association of Spondylitis and Aortic Aneurysm Disease

OBJECTIVES

The aim of this study is to assess any relation between spondylitis and aortic aneurysmal disease by reviewing the current literature.

METHODS

A systematic search was undertaken using MEDLINE, EMBASE and CENTRAL databases till May 2019, for articles reporting on patients suffering from spondylitis and aortic aneurysm.

RESULTS

The most involved aortic segment was infrarenal aorta (56.9%). The lumbar vertebrae were more frequently affected (79.7%). Commonest symptoms were back pain (79.1%), fever (33.7%) and lower limb pain (29.1%). 55.8% of cases were diagnosed using computed tomography. The pathology was attributed to infectious causes in 25.1% of cases. 53.4% of patients were treated only for the aneurysm, 27.9% for both pathologies, while two patients solely for the vertebral disease. Endovascular aneurysm repair was chosen in 12.8% of cases. The 30-day mortality was 8.1% (7/86); mostly from vascular complications.

CONCLUSIONS

A synchronous spondylitis and aortic aneurysm may share common etiopathology, when an infectious or inflammatory cause is presented. The lumbar vertebrae are more frequently affected. Low quality data do not allow safe conclusion to suggest the best treatment option.

Pyogenic Spondylitis with Rapid Bone Destruction After Chemoradiotherapy for Tongue Cancer: A Case Report and Literature Review

Radiation therapy is a frequently used effective treatment for head and neck cancer. It has several adverse effects of which osteomyelitis is a late complication of radiotherapy. Although uncommon, when it occurs in the vertebral body, it results in pyogenic spondylitis, which can be fatal. We report a case of pyogenic spondylitis, observed 2 years and 5 months after chemoradiotherapy following surgery for the treatment of tongue cancer. The initial symptoms were fever and posterior cervical pain. Initial CT images showed no abnormality in the cervical spine. However, when CT and MRI were followed over time, bone destruction and abscess formation were observed at the C3 and C4 vertebral endplates. Hence, CT-guided puncture d rainage was performed from the anterior neck. The collected pus was d iagnosed as Class II pyogenic spondylitis by cytology and the culture test revealed the presence of Streptococcus agalactiae. The infection was successfully treated by drainage and antibacterial chemotherapy.

[Tuberculous Spondylitis - Diagnosis and Management]

Tuberculous Spondylitis - Diagnosis and Management Abstract. Despite a decreasing incidence of tuberculosis (TB) over the last decades in Switzerland, the frequency of newly diagnosed tuberculous spondylitis has remained stable. It occurs most frequently in old, immunocompromised persons and/or persons who have moved to Switzerland from TB endemic areas. It is a chronic manifestation of TB, which is characterized by 'cold abscesses', neurological deficits and kyphotic spinal deformity. Tuberculous spondylitis is often diagnosed with a delay, which can lead to higher morbidity and treatment complexity. Antibiotic therapy is essential in tuberculous spondylitis. Surgical interventions aim to obtain samples, decompress nervous structures, obtain pain control and, if necessary, deformity correction/stabilization. This paper provides an overview of the modern diagnostic and therapeutic management of tuberculous spondylitis in Switzerland.

[Spinal infection with spinal cord/cauda equina affection requires emergency handling]

Seventeen cases of infections in spinal structures were reported 2010-2017 to the Swedish Health and Social Care Inspectorate (IVO), a government agency responsible for supervising health care, for missed or delayed diagnosis. All patient records were scrutinized in order to find underlying causes and common factors. The delayed diagnoses were equally found among men and women and most frequent in in the age-group 65 to 79 years of age. The diagnostic delay most probably in many cases led to patient harm and avoidable sequelae, many with severe impairment for daily life. Several of the patients had a locus minoris resistentiae in the spine and in several cases the entry port of infections were cutaneous wounds, for example leg ulcers. The most important finding was that in the majority of cases the clinical investigation was inadequate and the clinical follow-up - while in hospital! - was inferior, without documentation of muscular weakness and sensory loss. In several cases a too passive management was found, when the losses eventually had become apparent, delaying surgical interventions.

Retrospective analysis of culture-negative versus culture-positive postoperative spinal infections

Retrospective analysis.This study aimed to investigate the characteristics, clinical features, and outcomes of culture-negative (CN) and culture-positive (CP) postoperative spinal infections (PSIs).Causative organism cultures and the use of adequate antibiotics are essential for treating postoperative spinal wound infections. However, managing infected surgical sites with negative wound culture results is a common clinical problem. Although the outcomes of microbiologically confirmed PSIs have been well studied, the outcomes and clinical characteristics of CN PSIs have not been previously published.Between January 1995 and December 2014, 69 patients diagnosed with PSIs were enrolled. Enrolled patients were classified into 2 groups: CN (28 patients) and CP (41 patients). Baseline data, clinical manifestations, specific treatments, and treatment outcomes were compared with the groups.The overall rate of CN PSI was 40.6% (28/69). Baseline data and clinical manifestations were similar between the 2 groups. There were no significant differences in the duration of parenteral antibiotic use between the CN and CP groups. Revision surgery was required less often for the CN group (64.3%) than for the CP group (87.8%) (P = .020). Revision surgeries were repeated 0.82 times/case in the CN group and 1.34 times/case in the CP group (P = .014). Treatment outcomes, such as poor radiologic findings, need for additional anterior surgery, extension of fusion to adjacent segment surgery, and total length of hospital stay, were not different between groups.Revision surgery was performed less often for the CN group than for the CP group. From the perspective of revision surgery, CN PSIs have better prognosis than CP PSIs. However, clinical presentations and radiologic prognoses were not different between the two groups. We suggest that CN PSIs may be treated in the same way as CP PSIs.

Spondylodiscitis: Diagnosis and Treatment Options

BACKGROUND

A recent population-based study from Denmark showed that the incidence of spondylodiscitis rose from 2.2 to 5.8 per 100 000 persons per year over the period 1995-2008; the age-standardized incidence in Germany has been estimated at 30 per 250 000 per year on the basis of data from the Federal Statistical Office (2015). The early diagnosis and treatment of this condition are essential to give the patient the best chance of a good outcome, but these are often delayed because it tends to present with nonspecific manifestations, and fever is often absent.

METHODS

This article is based on a systematic search of Medline and the Cochrane Library for the period January 2009 to March 2017. Of the 788 articles identified, 30 publications were considered.

RESULTS

The goals of treatment for spondylodiscitis are to eliminate infection, restore functionality of the spine, and relieve pain. Magnetic resonance imaging (MRI) remains the gold standard for the radiological demonstration of this condition, with 92% sensitivity and 96% specificity. It also enables visualization of the spatial extent of the infection and of abscess formation (if present). The most common bacterial cause of spondylodiscitis in Europe is Staphylococcus aureus, but tuberculous spondylodiscitis is the most common type worldwide. Antibiotic therapy is a pillar of treatment for spondylodiscitis and should be a part of the treatment in all cases. Neurologic deficits, sepsis, an intraspinal empyema, the failure of conservative treatment, and spinal instability are all indications for surgical treatment.

CONCLUSION

The quality of life of patients who have been appropriately treated for spondylodiscitis has been found to be highly satisfactory in general, although back pain often persists. The risk of recurrence increases in the presence of accompanying illnesses such as diabetes mellitus, renal failure, or undrained epidural abscesses.

Candida vertebral osteomyelitis (CVO) 28 cases from a 10-year retrospective study in France

Although increasingly frequent, little is known about the clinical presentation, radiological signs, and outcome of Candida vertebral osteomyelitis (CVO).We performed a nationwide retrospective study of laboratory-confirmed cases of CVO over a 10 year-period in France with a prolonged follow-up. We describe demographic, clinical, biological, and radiological characteristics of patients with CVO, patients' management, and long-term outcome and determine factors associated with a poor outcome.In total, 28 patients with laboratory-confirmed CVO were included. A prior systemic Candida infection was evidenced in 13/28 (46%), occurring a median of 6 weeks before CVO was diagnosed. Twenty-six of 28 (93%) had at least 1 underlying condition at risk of invasive fungal disease, and in 19/28 (68%) CVO was health-care related. C albicans was most frequently identified (21/28; 75%) Lumbo-sacral involvement was the most prevalent (20/28-71%). Nearly half patients had no fever at presentation, but all had pain. Initial antifungal therapy consisted in fluconazole in 15/28 (53%); surgery was needed in 5 (18%) cases.One-year mortality was 21% (6/28), directly related to fungal infection in 2 patients. Risk-factors associated with 1-year mortality were age (P=.02), a high Charlson comorbidity index (P = .001), and a shorter treatment duration (median, 3 months vs 6 months; P = .02). Among 22 patients who survived, the median follow up duration was 15.5 months (8-93.5); 10 had sequelae, consisting in pain in all and neurological deficit in one. A longer treatment duration was significantly associated with healing without sequelae (P = .04).CVO concerns patients with serious underlying conditions and risk-factors for invasive candidiasis. Prolonged antifungal treatment appears to improve survival without sequelae.

[Clinical characteristics and prognosis of cultured negative pyogenic spondylitis]

OBJECTIVE

There are limited data describing the clinical characteristics and prognosis of culture negative pyogenic spondylitis. The aim of this study was to investigate the treatment, prognosis and clinical characteristics of culture negative pyogenic spondylitis.

METHODS

A retrospective study reviewed 74 patients who were diagnosed with spondylitis in Peking University First Hospital from January 2010 to December 2015. A total of 27 patients suffered from pyogenic spondylitis. According to the pathogenic culture results, the patients were divided into two groups: culture negative group and culture positive group. The clinical characteristics and treatment outcomes between the two groups were compared.

RESULTS

The elder were more vulnerable to pyogenic spondylitis, and of the 27 patients, 12 patients were female and 15 male. All patients had no history of administration of antibiotics prior to obtaining culture samples. A causative germ was identified in 14/27 patients (51.9%) with Staphylococcus aureus being the most common pathogen. There was no significant difference between the two groups in the patient's age, gender, visual analogue score (VAS), predisposing factor, clinical symptom, sign and spinal segment (P>0.05). Erythrocyte sedimentation rate (ESR) (P=0.056) and C-reactive protein (CRP) (P=0.040) of culture negative group were lower in contrast to culture positive group. The incidence of vertebral abscess in culture negative group was higher than in culture positive group (P=0.046). After treatment, ESR dropped almost equally in both groups, and CRP dropped faster in the culture positive group (P=0.192). At last, there was no significant difference between the two groups in hospital stay, pain relief, open debridement operation rate, and recurrence rate of infection.

CONCLUSION

ESR and CRP of the culture negative patient were lower than those of the culture positive patient, and the incidence rate of paravertebral abscess was higher than that of the culture positive patient. After administration of antibiotics, there was no significant difference between the two groups in duration of antibiotics, open debridement operation rate and recurrence rate of infection. So, culture negative may not necessarily be a negative prognostic factor for pyogenic spondylitis. However, we should watch out for the drug resistant bacteria or double infection, due to the long term use of wide-spectrum antibiotic in culture negative patients.

[A case of Staphylococcus aureus meningitis associated with cryoglobulin-related renal failure and clinically mild encephalitis/encephalopathy with a reversible splenial lesion]

A 59-years old man, having untreated hypertension and diabetes, was admitted to our hospital because of lumbago and fever. A T2-weighted image of spine showed increased signal intensity of vertebra at L3 and L4. Methicillin-susceptible staphylococcus aureus (MSSA) infection was confirmed by blood culturing. Cerebrospinal fluid (CSF) analysis showed pleocytosis. Diagsosis of pyogenic spondylitis with bacterial meningitis was made. Diffusion-weighted magnetic imaging of the brain disclosed a focal hyperintense lesion in the corpus callosum which showed a low coefficient in the apparent diffusion coefficient mapping. This finding suggests a clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS). His symptoms temporarily ameliorated by antibiotic therapy. Two weeks later, however, his conscious level rapidly worsened to comatose state. Concomitantly he developed acute renal failure with severe proteinuria. Serum serology showed a positive cryoglobulin test. Mechanical ventilation, hemodialysis and steroid pulse therapy improved his consciousness with a resultant complete recovery of all symptoms. We emphasize the possible complications in some cases of MERS.

Exposure of Prebiopsy Antibiotics Influence Bacteriological Diagnosis and Clinical Outcomes in Patients With Infectious Spondylitis

The benefit of prebiopsy empirical antibiotics for patients with infectious spondylitis and the effect on clinical outcome are not well known. This study assessed the impact of prebiopsy empirical antibiotics in patients with infectious spondylitis. We retrospectively reviewed 41 adult in-patients with infectious spondylitis who received percutaneous endoscopic debridement and drainage (PEDD) at a tertiary care hospital from August 2002 to August 2012. The average patient age was 55.2 years old and causative bacteria were identified in 32 out of 41 biopsy specimens (78.0%) via the PEDD procedure, which has good diagnostic efficacy comparable to open biopsy. Seventeen patients (41.5%) received prebiopsy empirical antimicrobial therapy, and these patients were less likely to have positive cultures than those who did not receive preoperative antibiotics (64.7% vs 87.5%, P = 0.04). Patients with positive cultures had a better infection control rate (78.1% vs 67.7%) and were less likely to undergo subsequent open surgery. Patients given preoperative antibiotics were more likely to need subsequent open surgery (35.3% vs 16.7%, P = 0.02). From multivariate logistic analysis showed age at diagnosis to be an independent risk factor for the need of further surgery. There were no major complications following the PEDD procedure, except 2 patients had transient paresthesia in the affected lumbar segments. Prebiopsy empirical antibiotic therapy was associated with lower positive culture rate and an increased need for subsequent open surgery. Patients with positive cultures were more likely to have initially adequate treatment, better infection control, and better clinical outcome.

Bilateral Portal Percutaneous Endoscopic Debridement and Lavage for Lumbar Pyogenic Spondylitis

Common management approaches for spinal infections include conservative administration of antibiotics and aggressive surgical debridement. Minimally invasive endoscopic treatment has been reported and is gaining widespread attention because of its simplicity and effectiveness. This study retrospectively evaluated the clinical outcomes of bilateral portal percutaneous endoscopic debridement and lavage with dilute povidone-iodine solution in the treatment of patients with lumbar pyogenic spondylitis. From January 2007 to December 2011, a total of 22 patients diagnosed with single-level lumbar pyogenic spondylitis underwent bilateral portal percutaneous endoscopic debridement and lavage with dilute povidone-iodine solution at the authors' institution. Clinical outcomes were assessed by careful physical examination, visual analog scale pain score, modified MacNab criteria functional score, regular serologic testing, and imaging studies to determine whether percutaneous endoscopic debridement and lavage treatment was successful or if surgical intervention was required. Causative bacteria were identified in 19 (86.4%) of 22 biopsy specimens. Eighteen patients had satisfactory relief of back pain and uneventful recovery after this treatment. The success rate was 81.8% (18 of 22). Both visual analog scale and modified MacNab criteria scores improved significantly in successfully treated patients. No major surgical complications were noted, except for 3 patients who had residual or subsequent paresthesia in the affected lumbar segment. Percutaneous endoscopic debridement and lavage is a minimally invasive procedure that can yield a higher bacterial diagnosis, relieve back pain, and help to eradicate lumbar pyogenic spondylitis. It is an effective alternative treatment for patients with spinal infection before extensive open surgery.

An interesting case of childhood brucellosis with unusual features

Brucellosis is a zoonotic infection, which is still a major public health concern worldwide. Common clinical findings are usually nonspecific involving fever, arthralgia, myalgia, weakness and malaise. Since none of the symptoms of brucellosis is pathognomonic, it may have a similar course with various multisystemic diseases. In terms of focal involvement, sacroiliitis is the most common musculoskeletal manifestation in adult patients, while it is quite rare in pediatric patients. Blood culture is the gold standard in the diagnosis of brucellosis. In the absence of culture facilities, the diagnosis traditionally relies on serologic testing with a variety of agglutination tests such as the Rose Bengal test and the serum agglutination test. However, these agglutination tests are accompanied by frequent false negative results such as seen in prozone phenomenon, which may lead to diagnostic delays. In this article we present a rarely encountered pediatric brucellosis patient who had sacroiliitis-spondylitis, which are rarely reported in children, and exhibited prozone phenomenon in agglutination tests.

[Septic arthritis and spondylitis]

Septic arthritis and spondylitis in elderly adult are uncommon disease. But symptoms and signs of septic arthritis and spondylitis are an important medical emergency, with high mortality and morbidity. Delayed or inadequate treatment can result in irreversible joint destruction and neurological condition. Early diagnoses as well as prompt and effective treatment are essential for avoiding severe outcomes. In spite of advances in diagnostic imaging techniques, the incidence of septic arthritis and spondylitis appears to have been increased. The aging of the population, the widespread use of immunosuppressant therapies, including systemic corticosteroids, cytokines and anticytokines, and growing resistance to conventional antibiotics seem to be the major cause.

[Comparison of effectiveness between two surgical methods in treatment of thoracolumbar brucella spondylitis]

OBJECTIVE

To compare the effectiveness between the method of simple posterior debridement combined with bone grafting and fusion and internal fixation and the method of one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in the treatment of thoracolumbar brucella spondylitis so as to provide the reference for the clinical treatment.

METHODS

A retrospective analysis was made on the clinical data of 148 cases of thoracolumbar brucella spondylitis between January 2002 and January 2012. Simple posterior debridement combined with bone grafting and fusion and internal fixation was used in 78 cases (group A), and one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in 70 cases (group B). There was no significant difference in gender, age, disease duration, involved vertebral segments, erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) score, neural function grade of America Spinal Injury Association (ASIA), and kyphosis Cobb angle before operation between 2 groups (P > 0.05). The peri operation period indexes (hospitalization time, operation time, and intraoperative blood loss) and the clinical effectiveness indexes (VAS score, ASIA grade, Cobb angle, and ESR) were compared; the bone fusion and the internal fixation were observed.

RESULTS

Incision infection and paravertebral and/or psoas abscess occurred in 2 and 3 cases of group A respectively. All incisions healed by first intention and 2 cases had pneumothorax in group B. The operation time and the hospitalization time of group A were significantly shorter than those of group B (P < 0.05), and the intraoperative blood loss of group A was significantly lower than that of group B (P < 0.05). All of the cases in 2 groups were followed up 14- 38 months, 25 months on average. The VAS, ESR, and Cobb angle were significantly decreased at each time point after operation when compared with preoperative ones in 2 groups (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). The neurological function was significantly improved at 3 months after operation; there were 1 case of ASIA grade C, 14 cases of grade D, and 63 cases of grade E in group A, and there were 1 case of grade C, 11 cases of grade D, and 58 cases of grade E in group B; and difference was not significant (Z = 0.168, P = 0.682). The grafting bone fusion was observed in both groups. The fusion time was (8.7 ± 0.3) months in group A and (8.6 ± 0.4) months in group B, showing no significant difference (t = 0.591, P = 0.601) was found. At last follow-up, no loosening or fracture of internal fixation was found.

CONCLUSION

Based on regular medicine therapy, the effectiveness of the two methods is satisfactory in the treatment of thoracolumbar brucella spondylitis as long as the operation indications should be controlled strictly.

[Systemic and local antibiotic therapy of conservative and operative treatment of spondylodiscitis]

An evidence-based recommendation for a standardized antibiotic therapy of spondylodiscitis has not yet been published. Crucial for conservative therapy is the verification of the causative organism and an appropriate antibiotic therapy. Intravenous antibiotic therapy should be administered for 2-3 weeks and a switched to oral administration for 6-12 weeks is then possible. If an empirical antimicrobial therapy is required a combination of ciprofloxacin and clindamycin, alternatively a combination of cefotaxim and flucloxacillin is recommended. Surgical removal of the infection by extensive debridement with stabilization and filling the resulting bone defect is desirable. Under the perception of a high local dose of antibiotic the defect filling with a mixture of cancellous bone and antibiotic-loaded hydroxyapatite and calcium sulfate is advisable.

[Pyogenic spondylodiscitis: therapy algorithm and a new classification for therapeutic decision-making]

The incidence of pyogenic spondylodiscitis is low but has been steadily increasing in recent years. To date there has been no consensus concerning selection of the appropriate treatment, management and strategies and the recommendations for an operative strategy are still a highly controversial issue. In the literature a few statements have been published concerning therapeutic decision-making in pyogenic spondylodiscitis. The classification given in this article is based on clinical experience and retrospective data analysis considering the degree of segmental bony destruction, grade of kyphosis and instability, epidural involvement of the disease and neurological deficits, which are pivotal for therapeutic decision-making. The therapeutic procedure can be defined based on this classification.

[Spondylogenic visceropathies]

A group of 830 patients with spondylogenic visceropathies was divided into three with clinical symptoms of bronchial (n = 80), cardiac (n = 530), and abdominal (n = 220) vertebral syndromes. Their clinical features, differential diagnosis and methods of treatment are described.

[Case of infectious spondylitis presenting as exudative pleural effusion]

A 59-year-old woman with lumbago, presented with cough and right chest pain. Her chest X-ray showed right pleural effusion, and laboratory studies revealed elevated levels of serum C-reactive protein. Right bacterial pleuritis and empyema was diagnosed based on an analysis of the pleural effusion and pus. She was treated with antibiotics and both the right pleural effusion and pus were drained with a chest tube. Staphylococcus aureus was cultured from the pleural effusion and pus. Her fever and chest pain improved after this treatment, however, the lumbago took a sharp turn for the worse. A spinal MRI showed an increased signal intensity at the level of T11-12, thus suggesting a disk space infection and spondylitis with an epidural abscess. Thereafter, she developed left pleural effusion, and the effusion was drained. Her infection was cured with long-term administration of antibiotics. However, the infectious spondylitis relapsed after four months, and she therefore had to undergo surgery. This case suggested that infectious spondylitis produced the exudative pleural effusion. Bacterial pleuritis, empyema and exudative pleural effusion must therefore be treated while keeping in mind the possibility of infectious spondylitis.

Management of a post-operative multi-resistant infectious spondylitis associated with a kyphotic deformity

Anterior spinal infection (prevertebral abscess and/or discitis) after posterior instrumentation for vertebral fractures is a challenging complication, since a new implant may become necessary anteriorly, in a septic environment. Generally accepted management guidelines are yet to be established. The authors present a case of posterior instrumentation for fractures of T12 and L1, complicated after 9 months with an anterior infection (prevertebral abscess and discitis) with extended-spectrum beta-lactamase (ESBL) producing Escherichia coli (E. coli). This case is unique in that the multi-resistant organism was isolated only after the second stage of infection treatment, which consisted of anterior débridement and anterior implantation of titanium cages and rods. In this particular case, infection was controlled despite implantation of multiple cages, screws and rods, and fusion was achieved, by means of intravenous antibiotic treatment for 12 months. At the latest follow-up, 24 months post surgery, there was no evidence of infection. This problem case may be helpful for surgeons confronted with spinal deformities secondary to infections with multi-resistant organisms.

[Tuberculous spondylitis in children and adolescents: results of treatment]

The results of treatment for tuberculous spondylitis were studied in 160 children and adolescents receiving different chemotherapy regimens and in 145 after application of the currently available surgical methods. When an individual regimen was used in 1990-2000, recovery was achieved in 90.8 +/- 2.9% of cases; recurrent vertebral processes were observed in 7.1 +/- 2.5%. With the routine regimen, controlled treatment was terminated in 81.0 +/- 5.2% of cases and the number of recurrent vertebral processes was increased by 11.8 +/- 4.6%. With the DOTS-Plus regimen, treatment was completed in 91.0 +/- 4.1% of cases. Mycobacterium tuberculosis cultures were isolated from postoperative biopsy specimens in 6.8 +/- 3.5% of the 154 operated patients. The author presents the results of reconstructive operations using a free-pedicle autograft and a myovascular graft. In the late period, the operated vertebral portion was fixed to form a bone block in 83.3 +/- 5.6 to 88.0 +/- 7.9% of cases. There was an increase in spinal deformity in patients with a disseminated vertebral process.

Rupture of a nonaneurysmal abdominal aorta due to spondylitis

Contiguous arterial infections are extremely rare, and their actual rate of occurrence is not known. These infections occur as a result of direct invasion of an artery from an adjacent septic focus. Reaching the diagnosis of infected aorta is very difficult when there are contiguous infections from spondylitis or psoas abscess, because the clinical features are nonspecific. Although computed tomography is the most useful diagnostic tool in the detection of aortic infections, the most frequent findings mimic those of other diseases, such as retroperitoneal fibrosis, lymphoma, and periaortic lymphadenopathy. Diagnosis becomes even more challenging when an infected aorta is of normal diameter. Herein, we report the case of a 64-year-old man who experienced nonaneurysmal abdominal aortic rupture due to spondylitis and psoas abscess. Despite appropriate surgical management, the patient later died. We review the relevant medical literature and examine specific considerations that surround the diagnosis and treatment of this rare condition.

[Infectious spondylitis]

Vertebral osteomyelitis or spondylodiscitis is an uncommon, mainly hematogenous, disease that usually affects adults. The incidence of this condition has steadily risen in recent years because of increases in spine surgery and nosocomial bacteremia, aging of the population, and intravenous drug addiction. Pyogenic infection due to Staphylococcus aureus is the most frequent form of the disease, but tuberculosis and brucellosis are still common causes of spondylitis in Spain. The clinical presentation is nonspecific and the diagnosis is often delayed. Magnetic resonance imaging is the most sensitive radiologic technique for this disease. Blood cultures are often positive, but computed tomography-guided needle biopsy or surgical biopsy of the affected vertebra is sometimes required to achieve a microbiological diagnosis. Prolonged antibiotic therapy and occasionally surgery are essential for cure in most patients, and both factors have contributed to a reduction in the morbidity and mortality of the disease in recent years.

[Radon therapy in medical rehabilitation of patients with seronegative spondyloarthritis. An open controlled study]

Radon therapy of seronegative spondylitis in 213 patients proved much more efficient than symptomatic drug therapy due to its beneficial effect on peripheral arthritis and enthesitis. It stimulated cellular immunity and improved the quality of life in patients with seronegative spondyloarthritis to a higher degree compared with medicamentous treatment.

Spontaneous infective spondylitis and mycotic aneurysm: incidence, risk factors, outcome and management experience

Infective spondylitis occurring concomitantly with mycotic aneurysm is rare. A retrospective record review was conducted in all cases of mycotic aneurysm from January 1995 to December 2004, occurring in a primary care and tertiary referral center. Spontaneous infective spondylitis and mycotic aneurysm were found in six cases (10.3% of 58 mycotic aneurysm patients). Neurological deficit (50% vs. 0; P < 0.001) is the significant clinical manifestation in patients with spontaneous infective spondylitis and mycotic aneurysm. The presence of psoas abscess on computed tomography (83.3% vs. 0; P < 0.001) and endplate destruction on radiography (50% vs. 0; P < 0.001) are predominated in patients with spontaneous infective spondylitis and mycotic aneurysm. Of these six patients, four with Salmonella infection received surgical intervention and all survived. Another two patients (one with Streptococcus pyogenes, another with Staphylococcus aureus) received conservative therapy and subsequently died from rupture of aneurysm or septic shock. Paravertebral soft tissue swelling, presence of psoas abscess and/or unclear soft tissue plane between the aorta and vertebral body in relation to mycotic aneurysm may indicate a concomitant infection in the spine. In contrast, if prevertebral mass is found in the survey of spine infection, coexisting mycotic aneurysm should be considered.

Mud-bath treatment in spondylitis associated with inflammatory bowel disease – a pilot randomised clinical trial

OBJECTIVES

The objective of this study was to evaluate the effects and the tolerability of mud packs and thermal baths in a group of patients affected with this disease.

METHODS

Twenty-four patients with spondylitis and Crohn's disease or ulcerative colitis, treated with 5-ASA or sulfasalazine, were randomised and assessed by an investigator independent from the spa staff: 12 were submitted to a cycle of mud-bath treatment (12 mud packs and 12 thermal baths over a period of two weeks) and 12 were enrolled as controls. Patients were evaluated by BASDAI, BASFI, BAS-G and VAS for back pain before, at the end of a cycle of mud-bath treatment, and after 12 and 24 weeks. C reactive protein serum levels detected by high sensitivity nephelometric method and gut symptoms evaluated by CDAI or Powell-Tuck index were assessed at the same time periods.

RESULTS

A significant reduction of clinical evaluation indices of spondylitis was observed at the end of the cycle of mud-bath treatment. BASDAI50 improvement remained significant until the end of the follow-up (24 weeks). C reactive protein serum levels didn't show significant changes. No patient referred any gut symptom exacerbation. No significant changes in clinical evaluation indices, in IBD activity indices and in CRP serum levels were observed in the control group.

CONCLUSION

Mud-bath treatment in patients with spondylitis associated with inflammatory bowel disease is well tolerated and may improve spinal symptoms and function for several months.

Continuous irrigation in pyogenic spondylitis accompanied by iliopsoas abscess

STUDY DESIGN

A retrospective assessment of 12 patients with pyogenic spondylitis accompanied by iliopsoas abscess treated by continuous irrigation with our new method between March 2003 and July 2005.

OBJECTIVES

To present our method of treatment and to evaluate outcomes of 12 patients undergoing it.

SUMMARY OF BACKGROUND DATA

Since patients with pyogenic spondylitis accompanied by iliopsoas abscess who require surgery are often immunocompromised hosts, open surgery may be excessively invasive. A less invasive operative procedure is therefore desirable for them. Percutaneous drainage is often used for secondary iliopsoas abscess due to pyogenic spondylitis. However, some authors have emphasized the importance of spondylitis as the primary source of infection for secondary iliopsoas abscess and have considered it essential to combine abscess drainage with curative treatment of the primary focus of infection.

METHODS

We describe our treatment, which involves continuous irrigation using a saline infusion tube inserted into the infectious spondylitic disc as the primary lesion and insertion of a drainage tube into the iliopsoas abscess communicating with the primary lesion. Clinical and radiographic assessment of all 12 patients who received this treatment was performed.

RESULTS

Ten (83%) of the 12 patients responded well to this treatment, with clinical results overall. Back pain, a major symptom, was relieved a mean of 9 days after the start of continuous irrigation. The mean duration to remission of C-reactive protein was 30.2 days. Follow-up MRI and CT with enhancement revealed disappearance or near-total resolution of the iliopsoas abscess cavity with healing of pyogenic spondylitis in all 10 patients who responded well to our treatment.

CONCLUSION

This treatment is minimally invasive and useful in carefully selected patients with pyogenic spondylitis complicated by iliopsoas abscess.

[Infection of intervertebral space and the interventional therapy]

OBJECTIVE

To investigate the effect of interventional therapy in the treatment of intervertebral space infection.

METHODS

The needle was punctured into the infected intervertebral space from the post-lateral side of the spine monitored by X-rays. The pus was drained, the degenerative disc tissues and necrosis tissues were excised and taken out, and at the end a drainaging catheter was put into the space through the needle. The patient should lie in bed absolutely. The antibiotics was injected into the space through the silicon catheter every day. Three to four weeks later, the catheter was removed.

RESULTS

All the 8 patients got good results after the therapy. The low back pain was dramatically alleviated instantly at the day of operation. Erythrocyte sedimental rate gradually descended. After 3 approximately 4 weeks of treatment,the catheter was removed.

CONCLUSION

Interventional therapy of the intervertebral space infection has notable advantage over the open operation.

Spinal brucellosis: Turkish experience based on 452 cases published during the last century

BACKGROUND

Spinal brucellosis continues to be the leading cause of morbidity from infectious disease in the infested regions of the world, particularly in the rural areas including Turkey. The purpose of this review was to present the Turkish experience by analyzing the literature on the management of spinal brucellosis during the last century.

MATERIALS AND METHOD

To establish new guidelines for the diagnosis and treatment of this disabling health problem, publications reported from Turkey in national (n = 27) and international (n = 37) journals during the last century and databases containing medical literature were analysed.

RESULTS

It was observed that the number of articles produced by Turkish authors regarding spinal brucellosis has tremendously increased throughout the study period. Although the total number of reported cases with spinal brucellosis from a total of 34 secondary or tertiary referral centers in Turkey was 452, only cases having detailed information were evaluated for further analysis according to inclusion/exclusion criteria. Despite the inherent limitations, this type of study clearly indicates that the incidence of brucellosis has not decreased in Turkey over recent years. The clinical and radiological findings of brucellosis involving the spine were mostly atypical and it was difficult to diagnose this infectious disease owing to its nonspecific and variable clinical picture. Therefore, it may easily lead to a misdiagnosis of lumbar disc herniation or other spinal infections and a high index of suspicion is required to diagnose this condition in endemic parts of the world. In addition to serological tests, CT and/or MRI techniques were found to be sensitive for diagnosis and follow-up because they provide early diagnosis of lesions involving the spine and more accurate localization of intraspinal and paraspinal infestation by means of multiplanar images. Histologically, noncaseating granulomatous tissue and chronic inflammation were characteristic features of cases of brucellosis with spinal involvement.

CONCLUSIONS

Based on this critical review of literature from Turkey, it is concluded that early diagnosis and correct management are important to prevent the harmful effects of brucellosis and its complications, and that the treatment of choice is antibiotic therapy alone in most cases of brucellosis involving the spine.

Antibiotic–polymethylmethacrylate strut: an option for treating cervical pyogenic spondylitis

✓ Antibiotic–polymethylmethacrylate (PMMA) cement and beads constitute an effective system of local drug delivery of antibiotic agents in patients with bone and soft-tissue infections. Debridement followed by implantation of antibiotic–PMMA beads and systemic administration of antibiotic agents has achieved a 100% success rate in treating chronic osteomyelitis; however, there have been no reports of an antibiotic–PMMA strut for treating spinal pyogenic spondylitis. In this case report we describe a 57-year-old woman with C5–6 pyogenic spondylitis, progressive kyphotic deformity, and neurological deficits. The patient underwent anterior C-5 and C-6 corpectomy and spinal reconstruction in which we used an antibiotic–PMMA strut. The strut was 14 mm in diameter and contained PMMA and vancomycin powder. The operation was technically successful, and no complication related to anesthesia or the surgical procedure occurred. At the 12-month follow-up examination, dynamic radiographs revealed cervical spine stabilization. The patient’s neck pain subsided and she recovered neurologically with no residual infection. No antibiotic–PMMA strut dislodgment or failure was identified; however, 9.8% subsidence of the strut into the vertebrae was observed. The long-term outcome in this case requires further evaluation.

Macular degeneration in a case of Reiter's disease

Posterior uveitis is not a documented feature of Reiter's disease. We describe here a patient of Reiter's disease, who after a bout of dysentery in January 2002 developed macular edema of the right eye with visual acuity of 6/36. In December 2002, she was found to have phlyctenular conjunctivitis. In June 2004, when she reported with scaly plaques over both palms, repeat ophthalmological examination revealed macular degeneration of the right eye. The simultaneous occurrence of Reiter's disease and macular degeneration in this patient may be fortuitous but the immunological basis of both diseases suggests a possible association.

Pyogenic spinal infections and outcome according to the 36-Item Short Form Health Survey

Object

Pyogenic vertebral infections are rare. In most papers investigators have focused on risk factors, clinical characteristics, and diagnostic findings, and discussed different management strategies. The optimal strategy for dealing with spinal infections, however, remains controversial. Additionally, outcome data regarding quality of life (QOL) after pyogenic spinal infections are sparse. The aim of this study was to provide further data in this field.

Methods

The authors retrospectively investigated 62 patients suffering from pyogenic spinal infections. In 37 patients (59%), lumbar lesions were observed; thoracic and thoracolumbar infections were documented in 19 (31%) and a cervical infection was demonstrated in six patients (10%). Overall 28 patients (45%) underwent conservative treatment, and 34 (55%) underwent surgery with or without the placement of instrumentation. At follow-up examination the authors recorded each patient’s satisfaction as well as QOL according to the 36-Item Short Form Health Survey. Quality of life after treatment of pyogenic spine infections did not reach the level of the normative sample. Most patients continued to suffer some sort of pain. Despite different indications, the surgically treated patients experienced a slightly better QOL and self-reported satisfaction levels, as well as a statistically significant better outcome, than patients treated conservatively.

Conclusions

The results obtained in the present study suggest that surgery, especially in conjunction with the placement of instrumentation, may be more beneficial than conservative treatment in patients with a spinal infection.

[Melitococcal psoas abscesses: study of three cases and review of the literature]

Vertebral involvement is a common complication of brucellosis in adults. However psoas abscess related to brucellar spondylitis have rarely reported. The purpose of this report is to describe three cases of bilateral psoas abscess identified during workup for brucellar spondylitis. Medical imaging was helpful in confirming diagnosis of these fluid collections. Epidemiological, clinical, radiological and serological findings were consistent with melitococcal etiology. Treatment was based on a combination of antibiotics (rifampicine-doxycycline) and abscess evacuation by percutaneous drainage, needle aspiration or open surgery. Outcome was favourable. Brucellar psoas abscess is uncommon. Most caseare discovered coincidentally during investigation of melitococcal spondylitis. Management usually consists of fluid drainage and appropriate antibrucellar therapy. Prognosis is favourable.

Percutaneous drainage and continuous irrigation in patients with severe pyogenic spondylitis, abscess formation, and marked bone destruction

Object

The use of percutaneous suction aspiration has recently become viewed as an effective management strategy for pyogenic spondylitis unresponsive to conservative treatment. What remains unclear is whether it can be effective for severe pyogenic spondylitis in which abscess formation or marked bone destruction is present. The authors undertook a study to clarify answers to this question.

Methods

The authors evaluated clinical and radiographic/neuroimaging data obtained in five patients with severe pyogenic spondylitis, extensive abscesses, and marked bone destruction. These patients had undergone percutaneous drainage and continuous irrigation because open surgery was considered contraindicated in light of their poor general health. The mean period during which continuous irrigation was applied was 9 days (range 7–11 days), and the mean period during which the drainage tube was in place was 19 days (range 13–38 days). All patients suffered from back pain, which was relieved by the percutaneous technique in four patients after a mean of 8 days. The abscesses and inflammation resolved in all patients. Progressive osseous destruction was not observed, and open surgery was performed in only one patient in whom back pain persisted as a result of spinal instability.

Conclusions

After an unsuccessful course of conservative treatment, severe pyogenic spondylitis with abscess formation or marked bone destruction was successfully treated using percutaneous drainage and continuous irrigation. Based on their results, the authors believe that this procedure can be used in patients with severe pyogenic spondylitis that was unresponsive to conservative treatment, particularly in those whose general health is poor.

Tuberculous spondylitis in patients with end-stage renal disease undergoing chronic hemodialysis therapy

Tuberculosis of the spine is not rare in immunocompromised patients and particularly in those with end-stage renal disease (ESRD). Furthermore, the possible vascular compromise of the spinal cord in patients with diabetic nephropathy may result in symptoms of neurological involvement that could lead to deterioration and paralysis. We report a series of 4 patients with ESRD undergoing dialysis that developed tuberculous spondylitis of the thoracic spine. Diabetic nephropathy was the primary cause for chronic kidney disease in 2 patients; 3 of these patients were treated conservatively with anti-tuberculous medication and orthotic splints and were cured. The fourth patient with diabetes mellitus and clinically evident signs and symptoms of severe vascular insufficiency has additionally developed incomplete paraplegia. A complete sensory recovery and partial recovery of the hip flexors and abductors within 3 months occurred, following decompression of the spine and drainage of the abscess, in combination with long-term anti-tuberculous treatment and spinal orthosis.

Preliminary results with modified techniques of balloon kyphoplasty for vertebra plana, traumatic fractures and neoplasms

Percutaneous vertebroplasty and balloon kyphoplasty are less invasive treatment options than open surgery for patients with vertebral compression fractures. With balloon kyphoplasty, the injection of bone cement is preceded by inflation and removal of bone tamps (balloons) inside the fractured vertebral body. This allows for the creation of a void, where viscous cement is delivered resulting in a lower risk for cement leakage than with vertebroplasty. Another advantage of the balloon inflation is the potential to correct the deformity and restore sagittal alignment. The percutaneous techniques normally require intact pedicles and intact posterior elements. We found that modifying the technique made it suitable for the management of vertebra plana, traumatic fractures, and neoplasms. Our study documents the different modified techniques and the clinical results obtained within the first 21 patients.

Fungal infections of the spine

Fungal infections of the spine are relatively uncommon. Fungi such as Coccidioides immitis and Blastomyces dermatitidis are limited to specific geographical areas whereas cryptococcus, candida, and aspergillus are found worldwide. Candida and aspergillus are normal commensals of the body and produce disease in susceptible organisms when they gain access to the vascular system through intravenous lines, during implantation of prosthetic devices, or during surgery. For the other fungi, spinal involvement usually is the result of hematogenous or direct spread of organisms from an initial pulmonary source of infection. Involvement of the vertebral bodies can lead to vertebral compression fractures and gross deformity of the spine. Spread of infection along the anterior longitudinal ligament can lead to psoas or paravertebral abscesses. Early recognition of the disease requires a high index of suspicion, proper travel history, and a detailed physical examination. Treatment relies on the prompt institution of appropriate pharmacotherapy and constant monitoring of clinical progress. Resistance to medical therapy, spinal instability, and neurologic deficits are indications for débridement and stabilization with spinal fusion. Prognosis depends on the premorbid state of the patient, the type of fungal organism, and the timing of treatment.

Clinical assessment and medical treatment of spine infections

Spinal infections affect the vertebral bodies, the intervertebral disks, the spinal canal, and the paravertebral soft tissues and structures. A delay in diagnosis can result in spine deformity, substantial neurologic complications, and even death. Because of this, a high level of awareness is required by physicians in order to diagnose infections of the spine promptly. Advances in medical microbiologic testing and newer imaging methods have contributed considerably to the medical treatment of these infections. Through careful followup, less invasive approaches orchestrated by a multidisciplinary team that includes a spine surgeon, an infectious diseases specialist, and a neuroradiologist may be sufficient to treat patients with these infections. Research done through multidisciplinary collaborations will further advance our knowledge for the successful treatment of spinal infections.

Die infektiöse Spondylitis

Infectious spondylitis usually involves osteomyelitis in two adjacent vertebral bodies and the intervertebral disc (spondylodiscitis). The most common location is the lumbar spine, followed by the thoracic spine. Symptoms are nonspecific, leading to a delay in diagnosis, in many cases, of several weeks. A large number of infectious agents can cause vertebral osteomyelitis, usually reaching the vertebra by hematogenous spread. The most commonly isolated agent is Staphylococcus aureus. Spondylitis remains the most common skeletal manifestation of tuberculosis. As with other forms of osteomyelitis, microbiological diagnosis is essential for the choice of adequate therapy. The majority of cases can be cured with antibiotic therapy alone.

Tuberculous spondylitis of the lumbosacral region: long-term follow-up of patients treated by chemotherapy, transpedicular drainage, posterior instrumentation, and fusion

OBJECTIVE

Tuberculosis spondylitis of the lumbosacral region has rarely been documented in the literature. We present an 87-month follow-up study of 7 of 62 patients with tuberculous spondylitis of the lumbosacral region treated by chemotherapy, transpedicular drainage, posterior instrumentation, and fusion. The purpose was to prove the hypothesis that chemotherapy with transpedicular drainage and single-stage posterior instrumentation-fusion is enough for the prevention of lumbar kyphosis and sagittal offset in selected cases.

METHODS

There were four men and three women, with average age of 53 years. All patients underwent transpedicular debridement, posterior fusion, and instrumentation. We studied the following data for consideration in these patients: most involved vertebra, vertebral body loss, progress of kyphosis, and sagittal offset.

RESULTS

The fourth lumbar vertebra was the most commonly involved vertebral segment. The average preoperative kyphosis was 17.5 degrees and decreased to 5.4 degrees postoperatively. Mean preoperative and postoperative sagittal offset was 0.34 mm and -5 mm, respectively. The average postoperative sagittal offset was increased from -5 to -2 mm at the third month and henceforth remained unchanged. There was no recurrent infection.

CONCLUSION

We consider that transpedicular drainage, posterior instrumentation, and fusion constitute a less demanding operative technique for lumbosacral tuberculous spondylitis for the prevention of lumbar kyphosis and sagittal offset in patients without neurologic deficit and major vertebral body loss. This is the only lumbosacral tuberculous spondylitis series in which the patients were operated on with single-stage posterior surgery and merits a brief report in the light of the larger series.

Burkholderia pickettii spondylitis

STUDY DESIGN

Case report describing Burkholderia pickettii spondylitis in a healthy adult.

OBJECTIVES

To describe this very rare form of spondylitis and to discuss some of the difficulties in the diagnosis of B. pickettii spondylitis.

SETTING

Department of Orthopaedic Surgery, Nayoro City General Hospital, Japan.

METHODS

A 48-year-old woman presented with a complaint of severe back pain radiating from the right side of her chest. Plain radiographs of the spine showed osteolytic destruction of the right side of the T10 vertebral body at T10 level, with an involvement of the pedicle. Magnetic resonance image of the spine showed a low signal intensity from the T10 vertebral body on a Tl-weighted image and an increased signal intensity on T2-weighted sequence image. These lesions were enhanced when a contrast medium was used. The patient underwent open biopsy and specimens were collected through the right pedicle.

RESULTS

Diagnosis was established on the basis of direct identification of the microorganism. Histological findings were consistent with examination of B. pickettii spondylitis. Chemotherapy (intravenous cefepime and per os minocycline) resulted in complete cure.

CONCLUSION

B. pickettii is widely distributed in aqueous sources in nature and has not previously been considered to be an aggressive pathogen towards humans. This case report will help to improve our understanding of the ecology and virulent pathogenicity of this organism. A biopsy is an essential and reliable method for the early etiologic diagnosis, which will lead to prevent the development of more severe complications such as spinal cord compression.

Conservative management of tuberculous spondylitis in a developing country

BACKGROUND

Tuberculous spondylitis is a significant health burden in the Third world. Tuberculosis and its complications are on the increase because of the HIV/AIDS challenge. The aim of this study was to review the patients managed for tuberculous spondylitis at the University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria.

METHODS

This was a retrospective study of patients seen at the University of Port Harcourt Teaching Hospital between January 1999 and December 2002 with tuberculosis of the spine. Patients case notes were reviewed after collating out-and-in-patient records. Analysis was done using multiway frequency tables.

RESULTS

There were 16 males and 18 females, with a ratio of 1:1.1. Their ages ranged from 3.3 to 82 years with an average of 31.1. Peak ages of occurrence were the 3rd and 4th decades. Eighteen patients (52.9%) presented within the first 6 months of symptoms. The most frequent presenting symptoms were back pain, weight loss, difficulty with walking, low grade fever, and night sweats. The most frequent signs were gibbus and lower limb paralysis. The most common association was pulmonary tuberculous (32.4%). The thoracic spine was mostly affected, followed by the lumbar spine. Wedge collapse of the vertebrae was the common radiological finding. Twenty two patients had multilevel affection. Twenty patients (71%) had a lymphocyte differential of more than 45%, 87% had erythrocyte sedimentation rate of over 20 mm/hr. Westergren, and Mantoux test was positive in 55 percent of the patients. Twelve patients had outpatient treatment and 22 had in-patient treatment. Duration of hospital stay ranged from 7 to 157 days with an average of 62.6 days. All the patients had standard combination antituberculosis therapy. No patient had surgery for tuberculous spondylitis. Outcome of treatment was good (68.2%). Follow up was poor with a high default rate. There were 3 mortalities (8.8%).

CONCLUSION

Diagnostic delays partly due to lack of experience makes a high index of suspicion necessary to make a diagnosis. Outcome utilizing conservative methods of treatment is good.

Spondylitis following vertebroplasty: a case report

PURPOSE

Spondylitis is a rare complication of vertebroplasty with only one case report having been published to date. We report a further case of spondylitis after vertebroplasty that was managed successfully with conservative therapy.

METHODS

The clinical course of a 55-year-old patient with secondary osteoporosis due to liver cirrhosis from alcohol abuse is reported, in whom percutaneous vertebroplasty of three fractured vertebral bodies (L3-L5) was complicated by spondylitis at these levels.

RESULTS

Spondylitis of L3-L5 with paravertebral abscess formation and progressive collapse of L5 was detected by magnetic resonance imaging (MRI). Treatment consisted of percutaneous aspiration of the paravertebral abscess and antibiotic therapy. No bacteria was identified despite cultures have been taken before antibiotic treatment. The patient was treated with intravenous ciprofloxacin and consecutive clindamycin for a total of 3 months. One year after the infection the MRI signs of spondylitis have resolved without further collapse of L5. Painlevels have improved significantly, allowing the patient to return to work, but are still higher than immediately after vertebroplasty.

CONCLUSION

Spondylitis is a rare complication of vertebroplasty. In the presented case a satisfactory result could be achieved through conservative antibiotic therapy and restriction of movement.
