[Epidemiology of spinal diseases in nurses].

Epidemiology of spinal pathology among nurses. A cross-sectional study of 3300 German nurses was carried out in the course of an investigation of the prevention of occupation--related back problems. A much higher incidence of lumbar-spinal problems was observed than in a control group of office staff, not required to lift or carry. Evidence of much greater risk, especially of severe sciatic symptoms, was supported by a case-controlled study of patients with the diagnosis of disc-prolapse or disc-protrusion, carried out in two neuroradiology units. Nurses were significantly over represented. A lack of preventive measures for carrying and lifting patients was clearly demonstrated (availability and use of mechanical aids). To what extent the perception of spinal problems is influenced by psychological factors and not only by physical factors will be demonstrated by the recording of stress factors.

[Computed tomography in the diagnosis of spinal disease (author's transl)].

METHOD: During the period from October 1977 through February 1979, 41 cases of spinal diseases were studied by either EMI Whole Body Scanner, CT 5005 or EMI Head Scanner, CT 1010. Slices were 10 mm or 13 mm thick. MATERIALS: (1) disc diseases 15 cases (2) ossification of posterior longitudinal ligament 10 (3) congenital anomalies 5 (4) spinal cord tumors 6 (5) trauma 3 (6) narrow cervical spinal canal 3 (7) calcification of ligamentum flavum 1 (8) spinal arteriovenous malformation 1. Results obtained are as follows: 1) A precise determination of vertebral level scanned by C.T. is important. 2) Plain spinal C.T. is of diagnostic value in detecting bony lesions and lipoma. Meningioma showed positive images in the enhanced spinal C.T. 3) The spinal cord cannot be distinguished from the surrounding C.S.F. except for that at C1 level. 4) C.T. metrizamide myelography can appraise adjacent structures that may impinge on the spinal subarachnoid space, as well as structures contained in the space.

GFPT1 as a cross-ancestry validated target for degenerative spinal disease: genetic association in a Chinese cohort and functional characterization in zebrafish.

Degenerative spinal disease (DSD), including spinal stenosis and spondylosis, lacks effective pharmacological treatment. To identify druggable targets and assess cross-ancestry applicability, we integrate multi-omics analyses using Summary-data-based Mendelian Randomization (SMR), colocalization, and two-sample Mendelian randomization with European whole-blood, peripheral-blood, and CSF eQTL/pQTL datasets, followed by whole-genome sequencing (WGS) validation in a Chinese cohort. We identify 7 genes/proteins associated with spinal stenosis and 5 with spondylosis, with GFPT1, GPX1, and SERPINA1 shared by both. Two-sample MR further supports the causal associations of these targets with DSD. Phenome-wide MR prioritization selects GFPT1 and GPX1 as favorable candidates with no predicted adverse effects and potential beneficial effects on hypertension. In the Chinese cohort (67 lumbar spinal stenosis patients and 100 controls), WGS identifies 4 GFPT1 cis-eQTL loci (rs13016371, rs35392088, rs12997521, and rs13019789) associated with lumbar spinal stenosis risk; all risk alleles are linked to increased GFPT1 expression, and all 24 variant carriers show L4/L5 stenosis on imaging. Druggability analysis identifies IOX1 as the sole preclinical-stage compound targeting GFPT1, and molecular docking supports robust binding to GFPT1 (- 6.39 kcal/mol). Functional assays show that IOX1 directly inhibits GFPT1 enzymatic activity and induces fructose-6-phosphate accumulation. In zebrafish, IOX1 significantly rescues GFPT1-induced degenerative phenotypes. These findings establish GFPT1 as a cross-ancestry validated therapeutic target for DSD and nominate IOX1 as a promising disease-modifying candidate.

[Retropleural paraspinal approach in the treatment of anterolateral thoracic spinal diseases].

The personal experience in the treatment of the spinal and paraspinal thoracic pathology using the paraspinal retropleural approach is presented. A total of 18 patients with neoplastic, traumatic and discal lesions were operated on. Improvement of neurological disturbances and pain was noted in all patients. The surgical technique for spinal cord and root decompression and also for anterior and/or posterior stabilization of the spine is described. The paraspinal retropleural approach is compared with the anterior transthoracic approach. The advantages of the paraspinal retropleural approach are: low rate of complications; allows a very wide decompression of the neurological elements as well as an anterior and/or posterior stabilization of the spine by a single approach; and it can be easily tailored for each lesion. These advantages are enhanced in the management of lesions located in the upper thoracic or thoracocervical levels.

Clinical results of posterolateral fusion for degenerative lumbar spinal diseases: a follow-up study of more than 10 years.

The objective of this retrospective study was to evaluate the long-term clinical outcomes and the effects on unfused motion segments of posterolateral fusion. This study involved 35 cases (37 intervertebral levels) of posterolateral fusion performed to treat degenerative lumbar spinal diseases. There were 20 male and 15 female patients ranging in age from 30 to 67 years, with a mean age of 49 years. The postoperative period ranged from 10 years to 17 years and 8 months, with a mean period of 13 years. The clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA) score for assessment of treatment for low back pain. The effects on unfused motion segments were investigated with radiographic and magnetic resonance (MR) imaging. Postoperative satisfactory improvement (mean recovery rate, 66.9%) reached a plateau at 1 year and was maintained at final follow-up. Radiographically, the union rate was 86.5%. There were few cases of induced instability of unfused motion segments. On MR imaging, increased signal intensity in both T(1)- and T(2)-weighted images was seen in the paravertebral muscles in 15 of 20 cases (75.0%). Posterolateral fusion is a useful technique for the treatment of degenerative lumbar spinal diseases. Clinical outcomes were stable throughout follow-up. Instability of unfused motion segments rarely occurred.

Effect of spinal disease on successful arthrodesis in lumbar pedicle screw fixation.

OBJECT: Pedicle screw fixation with transverse process fusion has gained widespread acceptance since its inception. Improved rates of arthrodesis have been demonstrated when this technique is used. The authors present one of the largest series of patients to undergo this procedure at a single center; one of the goals was to correlate construct length and spinal disease with rates of successful arthrodesis by conducting a prospective analysis of lumbar fusion in which pedicle screws were placed. METHODS: During a 7-year period, the senior author performed pedicle screw fixation with posterolateral fusion in 457 patients; the mean follow-up period was 28.4 months. Indications for fusion included metastatic tumor, single-level degenerative disc disease (DDD), trauma, degenerative scoliosis, and translational vertebral instability. Successful fusion was based on the radiographic demonstration of a bilateral contiguous osseous bridge over the transverse processes and absence of movement on dynamic x-ray films. Fusion rates were lowest in cases of tumors (54%) and highest in cases of trauma (96%). In patients with single-level DDD the rate was 91%, and in those with translational instability it was 89%. Fusion rates, however, declined steeply in relation to each additional motion segment in the translational instability group. In this group a strong linear trend for proportion was demonstrated (p < 0.001). The overall fusion rate in patients with degenerative scoliosis was 70%. The overall fusion rate for the entire group was 86%. CONCLUSIONS: The data in this study can be used as a benchmark with which to compare newer technologies. Although overall pedicle screw-assisted fusion rate in cases of trauma or selected degenerative lesions approached 90%, the arthrodesis rates are not uniform for the different diagnoses. This appears to be related to the underlying spinal disease and the number of segments included in the fusion.

Epidural infusion pressure in degenerative spinal disease before and after epidural steroid therapy.

UNLABELLED: The analgesic mechanism of epidural steroids in reducing pain associated with degenerative spinal disease (DSD) is poorly understood. We report increased inline epidural infusion pressure in patients with DSD and assess whether this phenomenon is affected by administration of an epidural steroid injection. We collected data during epidural placement for routine surgery or epidural steroid therapy. Using a 17-gauge Tuohy needle, with patients in the right lateral decubitus position, loss of resistance to 2 mL of saline identified the epidural space. Two minutes later the needle was attached to saline-filled tubing connected to a pressure transducer (Baxter PX 260 pressure monitoring kit with Truwave TM disposable pressure transducer). In the first part of the study, 4 successive boluses of 3 mL of local anesthetic were administered at a rate of 6 mL/min to 15 patients (age 47 +/- 6 yrs) with radicular back pain and magnetic resonance imaging (MRI) or computed tomography (CT) evidence of DSD, and to 8 control patients with no history of back pain (age 44 +/- 5 yr) while inline epidural infusion pressure was measured. In the second part of the study 44 patients with low back pain and MRI or CT evidence of DSD presenting to the pain clinic were infused with 8 mL of 0.125% bupivacaine and 40 mg of methylprednisolone (20 mg/mL) at a rate of 6 mL/min while inline epidural infusion pressure was measure and recorded. This was repeated 3 wk later. Initially, DSD patients had significantly increased infusion pressures over normals, which most likely reflects outflow resistance or obstruction. A significant decrease in inline epidural infusion pressure was observed after epidural steroid treatment. This change in pressure may indicate efficacy from epidural steroid injection. IMPLICATIONS: During injection into the epidural space we observed increased resistance in patients with degenerative spinal disease. This resistance was significantly less when measured 3 wk after an epidural steroid injection. This change in pressure may indicate efficacy from epidural steroid injection.

How does neuropathophysiology affect the signs and symptoms of spinal disease?

A complex relationship exists between back pain and the presence of spinal disease. Particularly in chronic situations, back pain and its behavioural and emotional consequences are as likely to reflect the influence of psychosocial factors as any underlying spinal pathology. Nevertheless, physical factors are clearly important and it is significant that whereas in normal discs only the outer third of the annulus fibrosus is innervated, a much more extensive innervation develops in the presence of degeneration. Inflammation, as evidenced by leukocyte infiltration and expression of inflammatory mediators, is associated with disc degeneration and serves to alter the neural responses resulting in local and referred pain. It is probable that similar inflammatory processes, as well as direct root compression, contribute to radicular symptoms following disc herniation. An appreciation of these mechanisms encourages the search for novel treatments and permits a more rational and effective use of existing strategies for relieving pain.

Comparative study of MR myelography and conventional myelography in the diagnosis of lumbar spinal diseases.

The purpose of this study was to investigate the usefulness of magnetic resonance (MR) myelography by comparing it with conventional myelography. MR myelography was performed on 40 patients (24 men and 16 women; mean age, 44 years) with lumbar spinal diseases. MR myelography was imaged three-dimensionally by fast spin-echo technique with fat suppression and maximum intensity projection. We assessed both the ability to provide the images of nerve root sheaths and the similarity of the findings to conventional myelography. Satisfactory images of nerve root sheaths in the lumbar region were provided almost equally by MR and conventional myelography. The images obtained by MR myelography were similar in quality to those obtained by conventional myelography. When combined with some other conventional MR imaging techniques, this diagnostic technique of imaging lumbar spinal diseases is further enhanced.

[Spinal diseases in a rheumatology hospital unit in Lomé (Togo)].

A retrospective study was conducted to determine the different kinds of spinal diseases in patients attending the rheumatology unit of Lomé hospital, Togo. Among the 4927 patients seen over a 5-year period, 1966 (40%) had spinal involvement. The disease observed were as follows: degenerative spinal disorders: 1872 cases (95%); infectious discitis: 41 cas (2.1%); spondyloarthropathies: 33 cases (1.8%); tumors: 20 cases (1.1%). Degenerative spinal involvement affected mainly lumbar and cervical spine. The only unusual clinical feature was that Schober's index was often normal. Lumbar spinal stenosis was common (233 cases, 12.4%), especially in females, and occurred at an earlier age than in the Western world. Ankylosing spondylitis features included mildness of extra-articular manifestations and an often negative family history. Pott's disease was de leading cause of infectious discitis. The present study suggests that spinal disorders are as frequent in Africa as in Western countries.

[History of the treatment of spinal diseases].

Identification and treatment of spinal disorders have been described for thousands of years. Nevertheless, systematic operative treatment was more or less impossible until about 200 years ago. During the second half of the last century, spinal surgery developed rapidly due to several technical improvements. This article summarizes the main aspects of the historical development of spinal surgery.

[Percutaneous computed tomography-guided biopsy in spinal diseases].

The use of percutaneous spinal biopsy (PSB) is on the increase in the field of interventional radiology. From July 1990 to December 1992 in the Department of Radiology in the Istituto Ortopedico Rizzoli, 74 patients (50 men and 24 women, mean age: 47 years old) underwent CT-guided spinal biopsy. This study was aimed at evaluating the diagnostic capabilities and accuracy of CT-guided percutaneous biopsy, which is considered as a simple, reliable and definitive method for histopathologic diagnosis. In our case histories, the total average accuracy rate, which varies according to the involved segment and to the kind of lesion to be examined, was 86%; in 14% of cases the excised tissue proved insufficient for histologic diagnosis. By allowing the histopathologic diagnosis to be made, CT-guided PSB proves a valuable technique to plan the treatment of primary/secondary neoplastic lesions or of inflammatory and dysmetabolic processes.

[Vertebroplasty in the treatment of spinal diseases].

The results of surgical treatment by vertebroplasty are analyzed in 28 patients with different spinal diseases. A procedure for percutaneous vertebroplasty with polymethyl methacarylate is presented. This miniinvasive method has been shown to be highly effective in treating vertebral hemangiomas, osteoporotic compression fractures, and vertebral metastases and in strengthening the anterior vertebral column as compared with anterior spondylosis in open surgical operations.

The role of MR imaging in evaluating metastatic spinal disease.

Fifty-eight patients with suspected epidural metastases were evaluated with MR imaging. Six patients were examined on two separate occasions. MR was judged to be diagnostic in 60 of the 64 examinations. Twenty-two patients also underwent myelography. MR was as diagnostic as myelography in all cases of epidural metastases. In addition, MR offered several advantages over myelography in the evaluation of metastatic spinal disease, including demonstration of paravertebral tumor extension, identification of additional osseous metastatic lesions, and visualization of areas of spinal cord compression occurring between areas of myelographic blocks. We conclude that MR imaging is the examination of choice for evaluating suspected metastatic spinal disease.
