The role of laparoscopic biopsies in lumbar spondylodiscitis.

The infection of an intervertebral disk is a serious condition. The diagnosis often is elusive and difficult to make. It is imperative to have appropriate microbiologic specimens before the initiation of treatment. We report the case of a 51-year-old woman with lumbar spondylodiscitis caused by infection after the placement of an epidural catheter for postoperative analgesia. A spinal magnetic resonance imaging (MRI) scan confirmed the diagnosis, but computed tomography (CT)-guided fine-needle biopsy did not yield adequate material for a microbiologic diagnosis. Laparoscopic biopsies of the involved disk provided good specimens and a diagnosis of Propionibacterium acnes infection. We believe that this minimally invasive procedure should be performed when CT-guided fine-needle biopsy fails to yield a microbiologic diagnosis in spondylodiscitis.

Endoscopic surgery on the thoracolumbar junction of the spine.

The thoracolumbar junction is the section of the truncal spine most often affected by injuries. Acute instability with structural damage to the anterior load-bearing spinal column and post-traumatic deformity represents the most frequent indications for surgery. In the past few years, endoscopic techniques for these indications have partially superseded the open procedures, which are associated with high access morbidity. The particular position of this section of the spine, which lies in the transition area between the thoracic and abdominal cavities, makes it necessary in most cases to partially detach the diaphragm endoscopically in order to expose the surgical site, and this also provides access to the retroperitoneal section of the thoracolumbar junction. A now standardised operating technique, instruments and implants specially developed for the endoscopic procedure, from angle stable plate and screw implants to endoscopically implantable vertebral body replacements, have gradually opened up the entire spectrum of anterior spine surgery to endoscopic techniques.

Mucormycosis spondylodiscitis after lumbar disc puncture.

Vertebral osteomyelitis due to mucormycosis is a rare but fulminant and fatal disease. Only one case has been reported in literature, with postmortem diagnosis. The present paper reports a female case of mucormycosis spondylodiscitis and vertebral osteomyelitis after lumbar disc puncture and radio frequency nucleoplasty. She subsequently underwent two surgical debridements, continuous local irrigation and drainage, together with local and systemic Amphotericin B treatments. The infection was controlled 4 months after the second debridement; however, there was no improvement in the neurological function at the most recent follow-up, 16 months after the surgery. The experience of this patient, though a single case, supports early recognition, surgical debridement, systemic and local antifungal treatment, closed irrigation and drainage as the keys to successful treatment.

Surgical treatment of spondylodiscitis in the cervical spine: a minimum 2-year follow-up.

Cervical spine spondylodiscitis is a rare, but serious manifestation of spinal infection. We present a retrospective study of 20 consecutive patients between 01/1994 and 12/1999 treated because of cervical spondylodiscitis. Mean age at the time of treatment was 59.7 (range 34-81) years, nine of them female. In all cases, diagnosis had been established with a delay. All patients in this series underwent surgery such as radical debridement, decompression if necessary, autologous bone grafting and instrumentation. Surgery was indicated if a neurological deficit, symptoms of sepsis, epidural abscess formation with consecutive stenosis, instability or severe deformity were present. Postoperative antibiotic therapy was carried out for 8-12 weeks. Follow-up examinations were performed a mean of 37 (range 24-63) months after surgery. Healing of the inflammation was confirmed in all cases by laboratory, clinical and radiological parameters. Spondylodesis was controlled radiologically and could be achieved in all cases. One case showed a 15 degrees kyphotic angle in the proximal adjacent segment. Spontaneous bony bridging of the proximal adjacent segment was observed in one patient. In the other cases the adjacent segments radiologically showed neither fusion nor infection related changes. Preoperative neurological deficits improved in all cases. Residual neurological deficits persisted in three of eight cases. The results indicate that spondylodiscitis in cervical spine should be treated early and aggressive to avoid local and systemic complications.

Spondylodiscitis and epidural abscess due to Candida albicans.

A 32-year-old woman, addicted to heroin, presented with a dorsal spondylodiscitis due to Candida albicans associated with epidural abscess. Antimycotic treatment was successful, and no neurosurgical decompression was necessary. To our knowledge, this is the first case of documented epidural involvement in candidal spondylodiscitis. The diagnosis of candidal spondylodiscitis should be considered in cases of para- or tetraplegia occurring in intravenous drug abusers.

Surgical treatment of aspergillus spondylodiscitis.

Four cases of aspergillus spondylodiscitis were treated with operative debridement and fusion. In this rarely encountered mycotic infection of the spine in immunocompromised patients rapid destruction of the intervertebral disc and vertebral bodies can occur. In advanced cases antimycotic drug therapy is thought to be ineffective and a forcing indication for surgery exists when the destruction is progressive and spinal cord compression is imminent or manifest. Spinal instrumentation can be of help in maintaining or restoring spinal stability and maintaining spinal alignment. In our four patients the aspergillus spondylodiscitis was successfully eradicated and fusion achieved. In two of three patients with a neurologic deficit, this deficit disappeared. Two patients died within 6 months after the operative treatment, due to complications related to the underlying illness. One patient was left with a subtotal paraplegia.

Bone scintigraphy in tuberculous spondylodiscitis.

Tuberculous affection of the spine can present in different ways. Plain radiographs may fail to show any abnormality. Bone scintigraphy can be a very useful tool in the diagnosis and management of patients with tuberculous spondylodiscitis. This is a retrospective study of 40 patients in whom bone scan was performed using 99mTc-MDP (technetium methylene diphosphonate) before starting anti-tuberculous therapy or any surgical intervention. Four different types of uptake were noted. The uptake was abnormal in 38 out of 40 patients, giving a sensitivity of 95%. Multicentricity was picked up in 25% of cases. No skull lesion was noticed in any of these patients. Rib lesions were found in six patients (ten ribs affected). The rib lesion was always a typical band pattern. This paper outlines the advantages as well as limitations of bone scan in tuberculous affection of the spine.

Fluorine-18 fluorodeoxyglucose positron emission tomography findings in spondylodiscitis: preliminary results.

Nuclear medicine procedures can be helpful in diagnosing spine infections. The purpose of the study was to evaluate the findings of positron emission tomography with fluorine-18 fluorodeoxyglucose (FGD-PET) in the detection of spondylodiscitis. We performed FDG-PET in 16 patients with suspected spondylodiscitis. All the patients were operated and underwent histopathological examination. The FDG-PET findings were graded and evaluated by two independent nuclear medicine physicians. Of the 16 patients, 12 had a histopathologically confirmed spondylodiscitis. In all these 12 patients, FDG-PET was true-positive. In the four patients without spondylodiscitis, FDG-PET showed three true-negative and one false-positive result. In spondylodiscitis, the mean standard uptake value (SUV) of FDG was 7.5 (SD+/-3.8). The PET scans depicted the paravertebral soft tissue involvement in cases of spondylodiscitis. Our first results showed that FDG-PET is a very sensitive imaging procedure in the detection of spondylodiscitis. Compared to other nuclear medicine procedures, PET enables a rapid imaging with acceptable radiation dose and high spatial resolution.

Macrophage tissue infiltration, clinical symptoms, and signs in patients with lumbar disc herniation. A clinicopathological study on 179 patients.

It is postulated that in addition to nerve-root compression, an inflammatory stimulus of the herniated lumbar disc is responsible for sciatic pain and radiculopathy. The clinical relevance of the histologically described inflammatory infiltrates is, however, not clearly defined [8, 22]. It was the aim of this study to assess the clinical relevance of inflammatory cells in herniated lumbar disc specimens. The presence of inflammatory cells was examined immunohistochemically in routinely processed resection specimens of the lumbar disc. The histological results were compared to prospectively obtained clinical data. Disc specimens of 179 patients who underwent surgery for lumbar disc herniation were studied immunohistologically. Preoperatively each patient received a visual analogue scale for classification of the pain level and general clinical data were recorded prospectively. Varying amounts of inflammatory cells could be demonstrated in the resected disc tissue. In the statistical workup no statistically significant correlation between the histological evidence of macrophage infiltrates and the pain grading scale or the clinical data could be found. In our study there is no statistically significant correlation between macrophage infiltrates in herniated lumbar disc specimen and the obtained clinical data.

Anterior cervical discectomy (ACD) versus anterior cervical fusion (ACF), clinical and radiological outcome study.

This study was conducted on 90 patients with symptomatic cervical disc disease with one or two-level disc pathology. Clinical and radiological outcome was compared to determine which technique was advantageous for patients with disc disease. Problems related to donor site as well as those related to fusion bed and grafts have stimulated investigators to avoid fusion. Patients were allocated at random for either the ACF (n=50) or the ACD (n=40) procedures. The standard Smith-Robinson technique was performed on all patients in this study. Patients were followed-up clinically and radiologically according to the study protocol. The clinical long-term outcome was comparable in both groups, though those who had ACF were more satisfied. There was significant incidence of kyphosis in the ACD group (P=0.02). Osseous union was slow and less satisfactory with ACD (64%) than with ACF (94%). Pain at the donor site was not a significant problem in the long-term. Hospital stay and operative time was shortened in ACD patients though not significantly. Spondylotic patients were less satisfied with ACD though not significantly. Conclusions. The issue of whether to fuse or not to fuse has not come to an end yet. The technique is still in need of more refinement of disc excision and graft harvesting and shaping, as well as more adequately controlled studies. Until that, ACD has to be limited to those patients with a soft single disc without spondylosis.

Spondylodiscitis as the first manifestation of Whipple's disease -a removal worker with chronic low back pain.

Whipple's disease is a rare systemic infectious disease caused by the actinobacterium Tropheryma whipplei. Spondylodiscitis is an extremely rare manifestation of the infection and has previously been described in only three case reports. We present a 55-year-old man with persistent lumbago and signs of systemic illness, but without any gastrointestinal symptoms or arthralgia. The signal response in the lumbar spine in magnetic resonance tomography, both native and after intravenous gadolinium administration, was compatible with spondylodiscitis at the L4/L5 level. Culture of a specimen obtained by radiographically guided disc puncture and repeated blood cultures remained sterile. Tropheryma whipplei was detected by PCR amplification in material obtained from the disc specimen, from a biopsy of the terminal ileum and from the stool. The histology of duodenum, terminal ileum, colon and disc material was normal and, in particular, showed no PAS-positive inclusions in macrophages. Long-term antibiotic treatment with sulphamethoxazole and trimethoprim was successful, with marked improvement of the low back pain and normalisation of the systemic inflammatory signs. The possibility of Whipple's disease must be suspected in the case of a 'culture-negative' spondylodiscitis even if there are no gastrointestinal symptoms and no arthralgia present.

Spondylodiscitis caused by viridans streptococci: three cases and a review of the literature.

Three cases of spondylodiscitis caused by viridans streptococci were observed within the course of 1 month. Although streptococci have been reported as the third most frequent cause of spondylodiscitis after staphylococci and gram-negative bacteria, alpha-haemolytic streptococci are rarely seen. The three patients presented with symptoms of low back pain; they felt well and did not have a fever or chills. Laboratory examinations revealed inflammation. Further examinations such as scintigraphy, computed tomography or magnetic resonance imaging were done. Bacteriological diagnosis was established by blood cultures in two cases and by needle biopsy of the disco-vertebral space in one. In one patient endocarditis was also documented. Because the prevalence of endocarditis was found to be higher in our cases of spondylodiscitis due to Streptococcus viridans than for other bacteria, the exclusion of this diagnosis must be pursued aggressively. These observations lead us to question if the spectrum of bacteria causing spondylodiscitis is undergoing a change. an aetiological agent could be isolated in 1168 patients (85.4%): in 48% a staphylococcus, in 28% a gram-negative bacterium and in only 10% a streptococcus. There were two cases of viridans streptococci (0.2%). These two cases together with other single case reports [14-22] account for 15 cases of spondylodiscitis due to alpha-haemolytic streptococci. Differentiation of the organisms to the species level was accomplished in six cases: S. mitis (3), S. sanguis (2) and S. anginosus (1). Although a multitude of organisms, bacterial as well as fungal, causing spondylodiscitis has been reported in recent years, almost all were single cases [23-42]. The unusual observation of three cases of spondylodiscitis due to alpha-haemolytic streptococci within 1 month prompted us to review the clinical and laboratory findings and to compare these cases with those caused by Staphylococcus aureus.

Spondylodiscitis due to Candida tropicalis as a cause of inflammatory back pain.

Spondylodiscitis may be either infectious or rheumatic in origin. In the latter case it may be seen more often in the context of spondyloarthropathies, giving rise to inflammatory back pain. We report the case of a man, affected by ulcerative colitis and carcinoma of the colon, who developed spondylodiscitis due to infection by Candida tropicalis.

Clinical and laboratory characteristics of infective endocarditis when associated with spondylodiscitis.

Spondylodiscitis is rarely observed in association with infective endocarditis (IE). In the study presented here, 92 cases of definite IE were examined. Spondylodiscitis was present in 14 (15%) cases. The mean age of patients with spondylodiscitis was 69.1+/-13.6 years (range, 33-87 years). The male-to-female ratio was 8:6. Predisposing heart disease was found in nine (64.3%) cases. Back pain was reported in all cases. Spondylodiscitis was diagnosed before endocarditis in all cases. The infection affected the lumbar spine in 10 (71%) cases. A bacterium was isolated in all cases: group D Streptococcus ( n=5; 35.7%), coagulase-negative Staphylococcus ( n=4; 28.6%), and others ( n=5). Endocarditis affected predominantly the aortic valve (43%). The outcome was favourable in 12 cases. No differences in clinical features, evolution of disease, or laboratory values were found between IE patients with and IE patients without spondylodiscitis. Spondylodiscitis does not appear to worsen prognosis of IE, although the need for cardiac valve replacement seems to be more frequent in IE patients with spondylodiscitis. IE should be included in the differential diagnosis in patients with infectious spondylodiscitis and risk factors for endocarditis. In such patients, echocardiography should be performed routinely.

Spondylodiscitis associated with bacteraemia due to coagulase-negative staphylococci.

Three cases are reported of spondylodiscitis caused by coagulase-negative staphylococci in patients without osteosynthetic material. All three patients had bacteraemia associated with an infected intravascular device left in place. On the basis of this observation, it is concluded that such devices should be removed promptly in cases of prolonged or relapsing bacteraemia. Furthermore, spondylodiscitis should be suspected in patients with back pain after bacteraemia caused by coagulase-negative staphylococci.

Microsurgical management of postoperative disc space infection.

We analysed seventeen patients with septic postoperative spondylodiscitis (POD) who were managed by early microsurgical removal of the infected necrotic tissue, application of a closed suction-irrigation system (for a mean of 6.7 days), and early mobilisation. The POD was diagnosed clinically by elevated erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) values and radiographically by computerised tomography scanning or magnetic resonance imaging. According to the sensitivity studies of the obtained pathogens, systemic antibiotics were given, followed by early mobilisation of all patients in a light cast corset. Immediate pain relief was noted in all patients except one, who required a third operation that was followed by rapid clinical improvement. Bacteriological diagnosis was obtained in 88% of the patients. Excellent or good clinical long-term results were achieved in 82% of the patients, whereas 18% had poor results. Elevated ESR/CRP values returned to normal ranges within 6 to 44 days (mean 15 days) after reoperation. All but one patient tolerated early mobilisation (within 2 to 4 weeks) well without any complication. Early microsurgical removal of the necrotic and infected tissue and application of a closed suction-irrigation system supported by specific antibiotic therapy should be considered an effective means to treat POD, thereby avoiding a prolonged period of unpleasant immobilisation for the patient.

[Spondylodiscitis in childhood].

Spondylitis is a rare disease in childhood and atypical symptoms frequently retard the diagnosis. From 1968 to 1988, 25 children with a diagnosis of spondylitis were treated in our orthopedic hospital. Anamneses, clinical symptoms, roentgenograms, and differential diagnoses are described for these cases. Spondylodiskitis represents a mild course of the disease in childhood. Tuberculous spondylitis was not present in any of the cases. The prognosis of childhood spondylitis is favorable, and surgical interventions were not necessary in our patients. Spondylitis healed with an ankylosis of one segment of the spine without essential disturbance of spinal function.
