A 41-year-old man presented with low-velocity gunshot injury in the right abdomen. Neuroimaging showed the bullet located in the L2-3 intervertebral disc space, but neurological examination found no abnormalities. Exploratory laparotomy was performed because of retroperitoneal hematoma. Two months after the gunshot injury, the patient presented with severe low back pain. Serial neuroimaging showed that the bullet had migrated in the intervertebral disc space. The bullet was removed via right L2 hemilaminectomy. The patient had no complaints after the operation. Early recognition and surgical intervention for bullets embedded in the intervertebral disc space may present with neurological and related complications. 相似文献

Bertolotti's syndrome is characterised by anomalous enlargement of the transverse process(es) of the most caudal lumbar vertebra which may articulate or fuse with the sacrum or ilium and cause isolated L4/5 disc disease. We analysed the elective MR scans of the lumbosacral spine of 769 consecutive patients with low back pain taken between July 2003 and November 2004. Of these 568 showed disc degeneration. Bertolotti's syndrome was present in 35 patients with a mean age of 32.7 years (15 to 60). This was a younger age than that of patients with multiple disc degeneration, single-level disease and isolated disc degeneration at the L4/5 level (p = 0.05). The overall incidence of Bertolotti's syndrome in our study was 4.6% (35 of 769). It was present in 11.4% (20 patients) of the under-30 age group. Our findings suggest that Bertolotti's syndrome must form part of a list of differential diagnoses in the investigation of low back pain in young people. 相似文献

The lumbar disc and low back pain. 总被引:6,自引:0,他引:6

The lumbar disc serves to sustain compression loads and is subject to tension and shear in forward bending and rotation. Its outer third is innervated and can be a source of pain. The annulus fibrosus may be injured in rotation and flexion of the lumbar spine and may become symptomatic as a ligamentous injury. Compression injuries of the disc are initially asymptomatic but may set in train a degradative process that, in time, leads to internal disc disruption, which becomes symptomatic as a result of chemical or mechanical irritation of nociceptors in the annulus fibrosus. Disc prolapse is but one possible end stage of internal disc disruption and represents the culmination of a series of destructive processes affecting the disc. This condition can be symptomatic while the external appearance of the disc remains normal and before nerve roots are affected in any way. 相似文献

To determine the significance of changes in motor performance as measured by lumbar dynamometry, serial lumbar dynamometry was performed on a group of 45 male Workers' Compensation patients with chronic "mechanical" low back pain and in a group of 20 healthy male volunteers. The patients were men aged 20-60 years, whose current episode of low back pain had lasted for at least 3 months (mean 19.5 weeks, range 12-47 weeks). Testing was performed at entry into a "back school" program of therapy and again 2 weeks and 4 weeks later. The control group showed a slight improvement in almost all variables of strength and range of motion between the first and second tests but no significant change between the second and third tests. This was consistent with a learning effect. The patient group was analyzed as a whole and also in two groups based on their response to the Waddell maneuvers at entry: Waddell score 0-2 (no excessive illness behavior) and 3-5 (excessive illness behavior). As a whole, the patients showed significant progressive improvement in most variables on successive tests. The group with the low Waddell score had significantly greater strength and range of motion than the group with the high Waddell score but the trend of improvement with time was similar in the two groups. The authors conclude that in this sample of patients with low back pain, serial lumbar dynamometry reveals a progressive improvement in performance, which is greater than the improvement expected from the natural history of physical recovery and greater than the improvement expected from an increase in strength and range of motion attributable to the therapeutic exercises performed and is much larger than any learning effect related to the test procedure. 相似文献

We report a case of a hernia through the thoracolumbar fascia in a young adult male who presented with pain and swelling in the thoracolumbar region. Surgical repair of the defect was performed in the superficial layer of the thoracolumbar fascia and, 18 months following surgery, he remained asymptomatic. The purpose of this report is to make clinicians aware of a thoracolumbar hernia as a rare cause of back pain. 相似文献

Summary Intraspinal synovial cysts, sometimes referred to as ganglion cysts, are uncommon lesions which may present as acute or chronic low back pain, with or without radicular symptoms. We present two patients who presented with back pain and radicular symptoms attributable to the unusual pathology of an intraspinal synovial cyst. 相似文献

Symptomatic synovial lumbar facet cysts are a relatively rare cause of radiculopathy and spinal stenosis. This case and brief
review of the literature, details a patient who presented with acutely symptomatic bilateral spontaneously infected synovial
facet (L4/5) cysts. This report highlights diagnostic clues for identifying infection of a facet cyst. 相似文献

Spinal fusion became what has been termed the “gold standard” for the treatment of mechanical low back pain, yet there was
no scientific basis for this. Operations of fusion for low back pain were initially done at the beginning of the last century
for back pain thought to be related to congenital abnormalities or for past spinal infection. The recognition of the disc
as a cause of sciatica, commonly associated with back pain, and the recognition that a degenerate disc led to abnormal movement
suggested the concept that this abnormal movement was the cause of pain, and this abnormal movement came to be called “instability”.
Much biomechanical expertise confirmed the fact that degenerate discs led to abnormal movement, there were many hypothesis
as to why this caused pain. However clinical results of fusion for back pain were unpredictable. The failure of pedicle screws
and cage fusion to improve the clinical results of fusion despite near 100% fusion success, and the introduction of “flexible
stabilization” and artificial discs, which demonstrated that despite the often unpredictable movement permitted by of these
devices, clinical success was similar to fusion, directed attention to the other role of the disc, that of load transfer,
which these devices also affected. Abnormal load transfer was already known to be critical in other joints in the body and
had led to the use of osteotomy to realign joints. The relevance of load transfer to the future design of spinal implants
used in the treatment of low back pain is discussed, and some finite element studies are reported demonstrating the likely
effect of abnormal loading beneath an incompletely incorporated plate of an artificial disc, perhaps explaining in part the
somewhat disappointing clinical results to date of the implantation of artificial discs. 相似文献

Acute renal artery occlusion is rarely found in daily clinical practice. Its rarity and inespecific clinical presentation are responsible for late diagnosis or diagnostic errors, with symptoms frequently being erroneously attributed to other more common entities. There is no consensus in what concerns therapeutic options. Multiple treatment modalities are described in the available literature. Some defend anticoagulant therapy and support measures only while others recommend other more invasive alternatives reaching even open surgery. The authors present two additional case reports of acute embolic renal ischemia. A thorough literature review is also presented comprehending etiological, clinic, diagnostic and therapeutic aspects. 相似文献

This paper reports 2 patients who developed chronic overuse tendinitis of the pelvic insertion of the sacrospinalis muscle. Despite prolonged courses of conservative therapy their symptoms did not improve. Following operative release of the sacro-spinalis, the symptoms settled dramatically and the function of their backs returned to normal. 相似文献

Introduction
Osteochondroma is a common benign tumor affecting bone that usually occurs in the appendicular skeleton rather than that in the axial skeleton. These lesions are more commonly reported with spinal involvement in cases of hereditary multiple exostoses.Case report
Symptomatic spinal osteochondromas generally occur in young adults in the second and third decades with local spinal pain, or neurologic deficit as more common manifestations. This report describes an unusual symptomatic spine osteochondroma in a 71-year-old man.Conclusion
Our case and review of the literature, only seven other cases of spinal symptomatic osteochondromas in elderly patients previously reported, suggest possible growth beyond skeletal maturity. 相似文献18.
