1/76. Cervical foraminotomy: an effective treatment for cervical spondylotic radiculopathy.Between 1983 and 1994, posterior cervical foraminotomy as described by Frykholm was performed on 89 patients with exclusively radicular symptoms caused by cervical osteophytes. The main presenting feature was arm pain. Objective neurological signs were present in 50% of the patients. At mean postoperative follow-up of 8.6 months, 95.5% of patients reported excellent or good results, while 4.5% were not improved. No patient was rendered worse following the procedure. There were no deaths and the complication rate was 2.2%. Further surgery for recurrent root symptoms was required by 6.7% of patients. Our findings are in keeping with the good results and low complication rate of this procedure as described in other studies. Informal inquiries suggest that this procedure is not widely used, at any rate in the United Kingdom, and we present this series in order to emphasize the efficacy and safety of this procedure.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
2/76. Fatal cervical spondyloarthropathy in a hemodialysis patient with systemic deposition of beta2-microglobulin amyloid.Destructive spondyloarthropathy is a serious complication in patients with end-stage renal disease. We report a case of fatal cervical spondyloarthropathy in a patient on hemodialysis who presented with severe pain in the cervical area. magnetic resonance imaging (MRI) of the cervical spine showed a soft tissue mass at the cervico-occipital hinge with spinal cord compression and destructive lesions of the cervical vertebrae. The patient became quadriplegic during the MRI procedure and died a few days later. Postmortem examination showed deposition of beta2-microglobulin in the cervico-occipital hinge. A unique feature of this case was the documented presence of systemic beta2-microglobulin amyloid deposits involving the spleen that to our knowledge has not been reported previously. Clinical suspicion and early detection of lesions caused by dialysis-related amyloidosis (DRA) may help to prevent significant morbidity and mortality in long-term dialysis patients.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
3/76. Can intramedullary signal change on magnetic resonance imaging predict surgical outcome in cervical spondylotic myelopathy?STUDY DESIGN: A retrospective study evaluating magnetic resonance imaging, computed tomographic myelography, and clinical parameters in patients with cervical spondylotic myelopathy. OBJECTIVES: To investigate whether magnetic resonance imaging can predict the surgical outcome in patients with cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA: No previous studies have established whether areas of high signal intensity in T2-weighted magnetic resonance images can be a predictor of surgical outcomes. methods: Fifty patients with cervical spondylotic myelopathy were examined by magnetic resonance imaging and computed tomographic myelography before surgery and by delayed computed tomographic myelography after surgery. The correlation between the recovery rate and the clinical and imaging parameters was analyzed. RESULTS: The best prognostic factor was the transverse area of the spinal cord at maximum compression (correlation coefficient, R = 0.58). The presence of high signal intensity areas on T2-weighted magnetic resonance images correlated poorly with the recovery rate (R = -0.29). However, patients with multisegmental areas of high signal intensity on T2-weighted magnetic resonance images tended to have poor surgical results associated with muscle atrophy in the upper extremities. Postoperative delayed computed tomographic myelography showed that multisegmental areas of high signal intensity on T2-weighted magnetic resonance images probably represent cavitation in the central spinal cord. CONCLUSIONS: patients with multisegmental areas of high signal intensity on T2-weighted magnetic resonance images tended to have poorer surgical results. However, the transverse area of the spinal cord at the level of maximum compression was a better prognostic indicator.- - - - - - - - - - ranking = 0.12396102343225keywords = upper (Clic here for more details about this article) |
4/76. High cervical disc lesions in elderly patients--presentation and surgical approach.The incidence of high cervical disc lesions is extremely rare, and the mechanism of their development is unclear. We report these three cases, and discuss the possible mechanisms. We also describe surgical strategies for these lesions. The first and second cases were an 82-year-old male and an 84-year-old male with retro-odontoid disc hernia. The third was an 83-year-old female with a herniated disc at C2/C3. To investigate Aetiological mechanisms of these lesions, we examined the findings on cervical images in extension and flexion, and compared the results in a younger than 80-year-old group and an older than 80-year-old group. The patients underwent surgery via a posterolateral intradural approach. Wide laminectomy and incision of the dentate ligaments enabled access to the ventral space of the upper cervical spinal canal and sufficient decompression. All patients became ambulatory postoperatively without special fixation of the cervical spine. In the younger group, the level mostly loaded during cervical movement was C5/6, however, the levels in the older group were C2/3 and C3/4. In elderly patients, less mobilization of the middle and/or lower cervical spine due to spondylotic change causes overloading at higher levels resulting in high cervical disc lesions. Retro-odontoid disc lesions can be caused by a herniated disc at C2/C3, which migrates upward. Regarding surgical strategy, the posterolateral intradural approach is less invasive and more advantageous for these lesions.- - - - - - - - - - ranking = 0.12396102343225keywords = upper (Clic here for more details about this article) |
5/76. Spondyloptosis and multiple-level spondylolysis.An unusual case of a combination of multiple bilateral spondylolyses (L2, 3 and 4), spondylolisthesis at L3/4, spondyloptosis at L4/5 and sacralization of L5 in a teenage female is described. The patient had severely increasing lower back pain radiating to the left lower limb. radiography identified the abnormalities and myelography revealed complete obstruction and compression of the thecal sac at the L4/5 level. The case was treated surgically by posterior decompression, corpectomy and fusion in a three-stage operation. The follow-up was extended to 2 years with no complications. No similar case has previously been reported.- - - - - - - - - - ranking = 6.380982361738keywords = back pain, pain, back (Clic here for more details about this article) |
6/76. Clinical observations on 278 cases of cervical spondylopathy treated with electroacupuncture and massotherapy.From Dec. 1990 to Dec. 1993, 278 cases of cervical spondylopathy were treated with electroacupuncture and massotherapy. The cure rate was 82.7%; but in the control group, it was only 61%, indicating that electroacupuncture may enhance the cure rate (P < 0.05). Of the 278 cases treated by three to five sessions, the pain and numbness disappeared in about 96% of the patients.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
7/76. Lumbar spine pain originating from vertebral osteophytes.BACKGROUND AND OBJECTIVES: Axial spine pain originates from a number of structures. Putative pain generators include facet joints, intervertebral disks, sacroiliac joints, and myofascial structures. Osteophytes originating from lumbar vertebral bodies in the area of the intervertebral disks may be a source of nociceptive low back pain which may respond to local injection. methods: Five patients with axial low back pain unresponsive to traditional treatment modalities were treated with fluoroscopic guided injection of local anesthetic and corticosteroid near large intervertebral osteophytes. RESULTS: All 5 patients experienced relief. CONCLUSION: Vertebral osteophytes may be a source of axial spine pain. Injection of painful osteophytes with a local anesthetic and corticosteroid solution may produce pain relief.- - - - - - - - - - ranking = 21.761964723476keywords = back pain, pain, back (Clic here for more details about this article) |
8/76. Cervical subarachnoid hematoma of unknown origin: case report.OBJECTIVE AND IMPORTANCE: Spontaneous spinal subarachnoid hematoma is rare, having been reported in the English literature in only seven other cases. We describe the first case of spontaneous subarachnoid hematoma located in the cervical spinal cord of a 43-year-old man. The pathologic examination showed no apparent source of bleeding, but there was evidence of cervical spondylotic myelopathy. CLINICAL PRESENTATION: The patient presented with a 10-day history of severe neck pain, followed by the onset of quadriparesis that was more evident on the left side, urinary retention, and sensory loss below C5. His medical history included hypertension. magnetic resonance imaging showed a massive hemorrhage in the cervical spinal canal. INTERVENTION: A C4-C5 subarachnoid hematoma was removed. The patient died due to respiratory distress and uncontrollable hypotension on day 6 after surgery. Surgical exploration, neuroradiologic examinations, and autopsy showed no evidence of vascular malformations, tumors, or other possible sources of bleeding. CONCLUSION: After excluding more common causes of spontaneous subarachnoid hematoma in this patient, we suggest that chronic spinal cord compression (spondylotic myelopathy) and arterial hypertension in this patient may have caused the pathogenesis of this rare clinical entity. Experimental data supporting this hypothesis are discussed.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
9/76. Contralateral spondylolysis and fracture of the lumbar pedicle in an elite female gymnast: a case report.STUDY DESIGN: The case of an elite female gymnast whose pathology started in her 12th year and whose evolution has been exceptional is reported. OBJECTIVE: To present a fracture of the right lumbar pedicle showing complete spontaneous consolidation despite gymnastic practice 15 hours a week. SUMMARY OF BACKGROUND DATA: Lumbar pain, which has an incidence of approximately 75% among young athletes, often results from diseases of the posterior arch of vertebrae in gymnasts, including spondylolysis. The association between unilateral spondylolysis and fracture of the contralateral lumbar pedicle in young athletes is poorly described. methods: An elite young female gymnast underwent clinical examination and lumbar radiographs (as systematically required by the French Federation for high-level gymnasts) from 1994 to 1997 to join a sports program in gymnastics. RESULTS: Clinical examination and lumbar radiographs systematically required of an asymptomatic female gymnast allowed the condensation of the right pedicle to be observed before lysis of the left isthmus of L5 in 1994, unilateral lysis of the left isthmus of L5 in 1995, a right pedicular fracture of L5 in 1996, and healing of the pedicular fracture in 1997. CONCLUSION: Inconsistency between radiographs and clinical observations can be noted, and spontaneous consolidation of pedicular fractures can occur despite the practice of the gymnastics 15 hours a week.- - - - - - - - - - ranking = 1keywords = pain (Clic here for more details about this article) |
10/76. Cervical spondylotic amyotrophy with intramedullary cavity formation.STUDY DESIGN: A case report. OBJECTIVE: To show that an intramedullary lesion was the cause of cervical spondylotic amyotrophy. SUMMARY OF BACKGROUND DATA: Cervical spondylotic amyotrophy is the clinical syndrome characterized by muscle wasting and weakness in the upper extremities without a remarkable sensory loss or spastic tetraparesis. It is still unclear whether the ventral roots or the anterior horn are selectively damaged. methods: magnetic resonance imaging and delayed computed tomographic myelography were performed on a patient who showed severe wasting of the left triceps muscle without any sensory disturbance or long tract sign. RESULTS: On sagittal magnetic resonance images, a linear area was noted within the spinal cord at C6 and C7 spinal segments, which showed low signal intensity on T1-weighted image and high signal intensity on T2-weighted image. On axial T1-weighted image intramedullary low signal intensity area was observed, which was located in the left anterior horn. On axial T2-weighted image the area showed high signal intensity. A delayed (6 hours) computed tomographic scan after intrathecal injection of metrizamide revealed intramedullary enhancement in the area corresponding to the left anterior horn, which would represent cavitation or cystic necrosis. CONCLUSIONS: This is the first case report of cervical spondylotic amyotrophy, in which intramedullary lesion was confirmed only at the affected side of the spinal cord.- - - - - - - - - - ranking = 0.12396102343225keywords = upper (Clic here for more details about this article) |
