1/52. The longer term effect of pulsed radiofrequency for neuropathic pain.pulse radiofrequency has been recently described as a technique to apply a relatively high voltage near a nerve but without the usual effects of a rise in temperature or subsequent nerve injury. In this set of case reports, the effect of pulsed radiofrequency (PRF) is described in patients with neuropathic pain syndromes which have been poorly controlled with other oral and invasive treatments. Whilst anecdotal, the results have been remarkable and should encourage further research into this technique. Observations from the basic science tend to support the concept that PRF may induce some sort of long-term depression in the spinal cord.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
2/52. sciatica in the community--not always disc herniation.Three cases of sciatica seen in general practice are described. The clinical features were consistent with pyriformis syndrome, a condition of compression of the sciatic nerve at the pelvic outlet. The literature on causes and clinical features is briefly reviewed. The prevalence of the condition in the community and the accuracy of clinical diagnosis are unknown. It is suggested that pelvic outlet syndrome, comparable to carpal tunnel syndrome, is a more appropriate name for the condition.- - - - - - - - - - ranking = 3keywords = syndrome (Clic here for more details about this article) |
3/52. Acute cauda equina syndrome caused by a gas-containing prolapsed intervertebral disk.Gas production as a part of disk degeneration can occur, but it rarely causes clinical nerve compression syndromes. A rare case of gaseous degeneration in a prolapsed lumbar intervertebral disk causing acute cauda equina syndrome is described. Radiologic features and intraoperative findings are reported. A 78-year-old woman with severe lumbar canal stenosis had acute cauda equina syndrome. magnetic resonance imaging revealed a large disk protrusion, and she underwent an urgent operation for this. Surgery confirmed the severe lumbar canal stenosis, but the disk prolapse contained gas that had caused the nerve compression.- - - - - - - - - - ranking = 7keywords = syndrome (Clic here for more details about this article) |
4/52. Bone metastases from a cerebral and sacral ependymoma. Report of a case.A case of cerebral and sacral ependymoma revealed by cerebellar syndrome and sciatica in a 68-year-old man is reported.

5/52. magnetic resonance imaging findings in piriformis syndrome: a case report.Piriformis syndrome (PS) is an unusual cause of sciatica that, because of the lack of strict diagnostic criteria, remains a controversial clinical entity. The diagnosis of PS is still primarily clinical because no diagnostic tests have proven to be definitive. We report the case of a 30-year-old woman, affected by a severe scoliosis, who developed a persistent buttock pain resembling that of PS. The clinical suspicion was confirmed by magnetic resonance imaging (MRI) of the pelvis, which showed an enlargement of the left piriformis muscle with an anterior isplacement of the sciatic nerve. The role of MRI in the diagnosis, clinical definition, and therapeutic approach to PS is discussed.- - - - - - - - - - ranking = 5keywords = syndrome (Clic here for more details about this article) |
6/52. Rapid progression of acute sciatica to cauda equina syndrome.OBJECTIVE: To demonstrate the importance of clinical examination and continued vigilance for neurologic deterioration in patients with sciatica. cauda equina syndrome, a rare sequela of sciatica, is considered a medical emergency requiring surgical decompression. Clinical Features: A 32-year-old woman had sciatica that rapidly progressed to cauda equina syndrome. magnetic resonance imaging revealed the presence of a large nonsequestered disk fragment in the lower lumbar spine. Intervention and Outcome: The disk fragment was surgically excised. The patient experienced immediate pain relief after surgery but retained neurologic deficits. After 6 months of rehabilitation, neurologic integrity was restored, aside from patchy sensory loss of the left foot and buttocks. At the 6-month follow-up, the patient's sciatica had not returned. CONCLUSIONS: Most cases of sciatica, regardless of cause, will self-resolve; as a result, there might be a tendency to maintain a low index of suspicion for serious, progressive disorders such as cauda equina syndrome. patients need to be educated as to signs of this emergency condition and informed as to the possible consequences of delaying treatment. By maintaining a high index of suspicion for any case that fails to respond as expected to a course of conservative therapy or that demonstrates signs of cauda equina syndrome, chiropractors can assume a pivotal role by investigating and referring appropriately and by aiding in active rehabilitation postoperatively.- - - - - - - - - - ranking = 8keywords = syndrome (Clic here for more details about this article) |
7/52. sciatica due to malignant nerve sheath tumour of sciatic nerve in the thigh.Malignant peripheral nerve sheath tumour (MPNST) is a rare malignant neoplasm arising from the supportive non-neural component of the peripheral nerves. An unusual case of pain and weakness of the foot and calf muscles due to a giant MPNST of the sciatic nerve in the posterior compartment of the thigh is presented. The patient was already investigated as a case of sciatica due to a lumbar disc disease with a negative magnetic resonance imaging and then unsuccessfully operated elsewhere twice, with a misdiagnosis of tarsal tunnel syndrome. Neurosurgical referral prompted a diagnostic magnetic resonance study of the thigh, revealing the lesion, which was completely excised microsurgically with total relief in the pain and partial improvement in the weakness and sensations in the sole of the foot.- - - - - - - - - - ranking = 1keywords = syndrome (Clic here for more details about this article) |
8/52. Swelling of the leg, deep venous thrombosis and the piriformis syndrome.BACKGROUND: The piriformis syndrome, which was first described 60 years ago, is a well recognized cause of sciatica, leg pain and low back pain, due to the entrapment of the sciatic nerve in the piriformis and other rotator muscles. Very few complications relating to this syndrome have been described. AIMS: To discuss how the piriformis syndrome may cause venous engorgement in the lower limb, and how the piriformis syndrome should be included as a possible cause of acute deep venous thrombosis in a not initially swollen leg. Both complications can occur independently. methods: Two cases of swelling of the leg and acute deep venous thrombosis independently associated with the piriformis syndrome are presented. CONCLUSIONS: Swelling of the leg and deep venous thrombosis are possible complications of the piriformis syndrome that occur due to entrapment of nerves and vessels within the leg, secondary to a severe spasm and hypertrophy of the piriformis and other rotator muscles.- - - - - - - - - - ranking = 10keywords = syndrome (Clic here for more details about this article) |

10/52. Gluteal compartment syndrome and sciatica after bone marrow biopsy: a case report and review of the literature.The gluteal region is not commonly thought of as a compartment, yet nondistensible osseofascial boundaries do exist. As with any case of compartment syndrome expedient therapeutic measures are critical to salvaging neuromuscular function. The gluteal compartment is unique, however, because of its tremendous muscle mass and great potential for producing devastating systemic sequelae. Gluteal compartment syndrome is most commonly associated with unconscious patients who are recumbent for prolonged periods, but trauma, spontaneous bleeding, and overexertion can also cause it. We present a case report of gluteal compartment syndrome after bone marrow biopsy of the iliac crest. Recognizing gluteal compartment syndrome as an entity and maintaining a high index of suspicion for its development especially in unconscious patients can avert disaster regardless of etiology.- - - - - - - - - - ranking = 8keywords = syndrome (Clic here for more details about this article) |
