Diagnosis and surgical treatment of disabling positional vertigo 总被引:2,自引:0,他引:2
This report reviews the characteristic symptoms of disabling positional vertigo (DPV), and the tests used to reach a differential diagnosis of this disorder. Twenty-one patients were operated on consecutively for management of DPV between March, 1983, and September, 1984. In all patients one or more arteries or veins was found to be compressing the eighth cranial nerve when the nerve was exposed for microvascular decompression to relieve the symptoms of DPV. After the operation, 16 of the 21 patients were free of symptoms, or symptoms were so much improved that the patients returned to normal work or social life. Two patients had no improvement and three had limited relief of symptoms postoperatively. None of the patients experienced hearing loss as a result of the operation to relieve DPV, but one patient suffered a cerebellar contusion during the operation. 相似文献

Two patients presenting with signs and symptoms suggestive of nerve root compression secondary to extradural masses were found to have ligamentum flavum hematomas. Both patients had neurological deficits preoperatively and regained normal function postoperatively. There was no significant antecedent injury in either case. The symptom course was longer than that for spontaneous epidural hematoma. In one case, there was remodeling of bone, initially suggesting either infection or tumor. 相似文献

AIM OF THE STUDY: Lesions of peripheral nerves are serious complications associated with total hip replacements. Prognostic factors and treatment concepts have not been sufficiently defined. Improvements can occur spontaneously. This study aimed to evaluate risk factors and diagnostic aids, such as the velocity of nerve conduction (VNC) and electromyography (EMG). Furthermore, the effect of prognostic factors as well as conservative and invasive therapeutic measures on the regression of clinical symptoms was examined. METHOD: From 1990 to 1996 1833 patients underwent total hip replacement. 1447 procedures were primary total hip replacements and 386 were revisions. 14 femoral nerve lesions (0.8%), 7 sciatic nerve lesions (0.4%) and 8 peroneal nerve lesions (0.4%) occurred. 19 patients were examined clinically, electromyographically and by means of VNC, 10 patients only clinically. In 5 patients a neurolysis was performed within the first postoperative year. All 29 patients underwent a recall examination in 1997 to evaluate the development of the clinical symptoms and if possible, VNC and EMG were performed. RESULTS: Of the 7 patients with sciatic nerve lesions, two were free from symptoms at the time of recall, two still complained about residual symptoms and two showed no improvement of the lesion. One patient did not appear for follow-up. Of the 8 patients with peroneal nerve lesions, five were free from symptoms at the time of their recent examination, two showed residual symptoms and one patient did not appear. Of the 14 patients with femoral nerve lesions, four had recovered completely, eight showed residual symptoms, one patient did not improve and one patient had died. CONCLUSIONS: Prognostic statements regarding the improvement after nerve lesions are possible only to a limited degree. However, it was found that the motor function tended to recover earlier than sensibility. We could not determine with clinical evaluations why some patients showed an improvement of their lesion while others did not. As well no clear correlation between the EMG and VNC results and the recession of the symptoms could be established. 相似文献

This study presents a retrospective review of the management of schwannomas in the limbs and examines the relationship between pre-operative clinical examination, operative findings and postoperative neurological complications. Eighteen tumours with a histological diagnosis of schwannoma in 17 patients who underwent surgery between 1998 and 2004 were the basis of this study. Enucleation of the tumour was possible in 14 cases. None of these patients had neurological complications pre-operatively but eight had mild neurological complications postoperatively. The complications consisted of sensory deficit in five cases, motor weakness in one and both in two. Enucleation of the tumours was impossible in four cases. These schwannomas originated in the brachial plexus in three cases and the ulnar nerve in the proximal arm in one case. Tumours with pre-operative symptoms and masses located at a proximal site in the limb were more likely to be impossible to enucleate completely. 相似文献

Introduction In this study, the results of ulnar nerve repair were analyzed. The relation between the functional outcome scores and clinical findings were investigated to find out whether any clinical finding could be predictive of the outcome.Materials and methods Seventeen patients who underwent ulnar nerve repair formed the study group. Average follow-up lasted 45.5 months (range 39–48 months), and average age of the study group was 31.7 years (range 26–42 years). The same operative technique was applied to all patients by one of the authors (HG). Follow-up checks were done at 3, 6, and 12 months postoperatively. The patients who did not attend the last follow-up were excluded from the study group. The Seddon classification was used as the functional scoring system. Wound healing, Tinel sign, interosseous atrophy, atrophy of the first web space, clawing, and protective sensation were the clinical findings examined at the follow-ups. Wound healing was classified as either normal scar formation or hypertrophic scar-keloid (HsC) formation.Results Good results in 4 and fair results in 13 were obtained according to the Seddon classification. Statistically, there was no difference between the clinical findings at the 3, 6, and 12 month follow-ups.Conclusion Presence of HsC and clawing can be regarded as a predictive sign for fair results in nerve repairs. 相似文献

Introduction Compression of the median nerve at the wrist by a persistent median artery is one of the uncommon reasons for carpal tunnel syndrome. Most of the studies in the literature deal with thrombosed persistent median artery.Materials and method In this study, we present surgical treatment of four carpal tunnel syndromes, which had persistent median arteries. The mean age of the patients was 51 years. All four median arteries were patent and only transverse carpal ligament releases were performed using a standard anterior open approach for decompression of the carpal tunnel. Neither ligation nor transposition of the arteries was done.Results All patients became symptom free after a few weeks. Only one patient had a slight recurrence 13 months postoperatively. Splint use and modification of her activities reduced her disturbance, and no further treatment was applied.Conclusion If the patient has no additional anomaly, our clinical experiences lead us not to advise resection or transposition because simple release of the transverse carpal ligament can relieve symptoms. 相似文献

Summary The outcome of 53 patients operated on either for posttraumatic ulnar neuropathy (PUN) or non-traumatic cubital tunnel syndrome (CTS) was reviewed after 3 years follow-up. Results were analyzed and compared considering the surgical technique used (neurolysis versus anterior transposition or combined) and a variety of clinical features that could influence outcome after nerve release. In the whole series, excellent outcome was obtained in 39 patients (73%). No major differences were found with the different surgical procedures. Slightly better results, but no statistically significant, were found in cases with CTS. As to clinical parameters, patients with CTS had a higher mean age, a shorter duration of symptoms and most were men. The presence of symptoms for more than one year before operation significantly diminished the chance of satisfactory recovery in cases with CTS, but not in those with PUN. For both CTS- and PUN-cases with symptoms for more than one year, neurolysis plus anterior transposition was the more useful technique. Our study shows that CTS and PUN differ to a certain extent in their clinical profile, electrophysiological findings and response to different surgical approaches and hence can be considered as two different clinical entities. 相似文献

A series of 12 patients with mass lesions arising from Meckel's cave is presented. Patients' age on presentation ranged from 13 months to 71 years. Nine of the 12 patients had symptoms referable to the fifth cranial nerve, but only three complained of facial pain. The 12 patients presented eight different pathological entities, including meningioma, lipoma, schwannoma, malignant melanotic schwannoma, arachnoid cyst, neurofibroma, epidermoid tumor, and chordoma. Computerized tomography and magnetic resonance imaging were most useful in localizing the lesion to Meckel's cave. All 12 patients underwent a subtemporal approach to the lesion, and gross total removal was achieved in 11. Postoperative results were excellent with no increased neurological deficits seen 3 months postoperatively. Most patients had resolution of the cranial nerve deficits except for fifth nerve function, which was impaired in nine patients postoperatively. This series demonstrates that lesions in Meckel's cave can have a varied and unusual presentation, as well as an assortment of pathology. Total removal of lesions in this area resulted in relief of symptoms in most patients, with minimum morbidity. 相似文献

STUDY DESIGN: Report of two cases of acute lumbar nerve root compression caused by myxomatous degeneration of the ligamentum flavum. OBJECTIVE: To report a rare cause of acute lumbar nerve root compression. SETTING: Orthopaedic department, Osaka, Japan. SUMMARY OF BACKGROUND DATA: Two patients, both 50-year-old men presenting with signs and symptoms suggestive of acute lumbar nerve root compression were found to have a ligamentum flavum mass. The masses were removed and the patients regained normal function postoperatively. METHODS: To reveal the nature of the mass, histopathological studies were made. Continuous sections were prepared from the removed mass lesions. The sections were stained with hematoxylin and eosin, van Gieson's stain, azan stain, periodic acid Schiff reaction, Alcian blue stain and von Kossa's stain. RESULTS: Histological examination revealed myxomatous degeneration of the ligamentum flavum. No elastic fibers were found at the degeneration site. Diffuse mucopolysaccharide deposition was found at the degeneration site, however, no cyst was found. Collagen fibers were not increased. Hypertrophy or ossification of the ligamentum flavum was not recognized in the sections. At a follow-up examination over 2 years later, the patients were free of symptoms and the findings of a neurological examination were normal. CONCLUSION: Two cases of myxomatous degeneration of the ligamentum flavum of the lumbar spine were reported, which have seldom been described as the cause of acute lumbar nerve root compression. 相似文献

PURPOSE: Ulnar neuropathy at the cubital tunnel (UCT) is diagnosed on the basis of history, physical examination, and nerve conduction studies (NCSs); however, the wide spectrum of findings often makes the diagnosis difficult. The purpose of this study was to document the ultrasonographic differences in ulnar nerve size between patients with UCT and control subjects, and to correlate those differences with clinical examination findings and NCS abnormalities, thereby testing the validity of ultrasound (US) as an additional adjunct diagnostic modality for UCT. METHODS: Fifteen elbows in 14 patients with symptoms, clinical examination, and NCS findings consistent with UCT had US of the ulnar nerve. Patients were excluded if they had a history of polyneuropathy, acute trauma involving the upper extremity, previous trauma in the region of the elbow (including previous surgery), or brachial plexus injury. The control group consisted of 60 elbows from 30 normal volunteers that also had US. Maximal cross-sectional areas (CSAs) were measured and compared for the 2 groups and a correlation analysis was performed between nerve size and NCS findings. RESULTS: The average CSA of the ulnar nerve was 0.065 cm(2) in the control group, whereas in the UCT group it was 0.19 cm(2), indicating a significant statistical difference in ulnar nerve size between the 2 groups. The Pearson correlation coefficient between motor nerve conduction velocity of the ulnar nerve and the CSA was 0.80. CONCLUSIONS: High-resolution US is a noninvasive, safe, and reliable modality for imaging the ulnar nerve at the elbow and it may provide a valuable adjunct to NCS in the diagnosis of UCT. 相似文献

BACKGROUNDCarpal tunnel syndrome (CTS) is one of the most common peripheral nerve compressive neuropathies. The clinical symptoms and physical examinations of CTS are widely recognised, however, there is still debate around what is the best approach for assessment of CTS. Clinical assessment is still considered the gold standard, however, controversies do exist regarding the need for investigations such nerve conduction studies (NCS) to aid with management decisions. AIMTo correlate the severity of NCS results to a scoring system which included symptoms, signs and risk factors.METHODSThis was a prospective correlation study. We scored patients’ signs and symptoms using our CTS scoring system. This was then correlated with the findings of the NCS. The scoring system included - four symptoms (2 Katz hand diagrams – one for tingling and one for numbness; nocturnal paresthesia and bilateral symptoms) and four clinical signs (weak thumb abduction test; Tinel’s sign; Phalen sign and hypoalgesia in median nerve territory) and two risk factors (age more than 40 years and female sex). We classified the NCS results to normal, mild, moderate and severe. RESULTSThere were 61 scores in 59 patients. The mean scores for the categories were as follows: 6.75 for normal NCS; 5.50 for mild NCS; 9.17 for moderate NCS and 9 for severe NCS. All scores of 8 or more matched with NCS results of moderate and severe intensity apart from three scores which were greater than seven that had normal NCS. Eta score was 0.822 for the CTS score being the dependent value and the NCS category being the independent variable showing a strong association between the scoring system and the NCS group.CONCLUSIONWe feel that this simple scoring system can be used to predict and correlate the severity of NCS in patients with CTS. 相似文献

The association of third cranial nerve palsy subsequent to an enlarging posterior communicating artery (P-Com A) aneurysm has been well described. In our current communication, we review the relevant literature and propose a classification system for the severity of the third cranial nerve palsy, correlating it to the postoperative recovery. Our four grade scale (I–IV) included the degree of the levator palpebrae muscle paresis, the presence of pupillary reaction and the impairment of the third nerve mediated extraocular muscle movement. We evaluated five patients with third nerve palsy secondary to non-ruptured, P-Com A aneurysm. Patients were re-evaluated at 2, 4, 8, 24 weeks postoperatively. Four of the five patients had complete recovery within 4–8 weeks after surgery. One patient had grade II third nerve paresis and complete resolution of the third nerve symptoms within 4 weeks, whereas three patients with grade III and IV had complete resolution 4–8 weeks after surgery. The fifth patient, with grade IV paresis, had minimal (grade III) improvement 6 weeks after surgery, and incomplete recovery (grade I) 6 months postoperatively. Our simple grading system of third nerve palsy associated with P-Com A aneurysms, can be a helpful tool for the initial evaluation and for the monitoring of recovery in these patients. 相似文献

Duplex ultrasonography after total hip or knee arthroplasty 总被引:5,自引:1,他引:4
We prospectively studied all patients admitted for total hip (THR) or knee (TKR) arthroplasty from July 2000 to February 2001. No pharmacological anticoagulation was given. All patients received a standardized postoperative rehabilitation regimen. Forty-six patients with known risk factors for deep vein thrombosis (DVT) were excluded. Eighty patients were studied (22 THR, 58 TKR; 55 women, 25 men). Mean age was 68 (30-90) years. Duplex ultrasonography on both lower limbs was performed on days 5-7 postoperatively. Location and extent of any thrombus were documented. In patients with distal DVT, a follow-up scan was done on days 10-14. If proximal propagation was observed, patients received full anticoagulation. If no propagation was detected, the distal thrombus was considered stable and clinical observation was continued. In the THR group, 1/22 and in the TKR group 9/58 were found to have distal DVT. All were asymptomatic. On follow-up scanning, none showed proximal propagation. All patients were followed up for at least 18 months, and none showed postthrombotic symptoms. Isolated distal DVT in "low-risk" Chinese patients after THR or TKR is not uncommon. Clinically they are usually "silent." If routine perioperative pharmacologic antithrombotic prophylaxis is not practiced, monitoring with duplex ultrasonography may need to be considered. 相似文献

Between January 1981 and February 1992, 102 non-NF-2 patients underwent removal of a unilateral vesitbular schwannoma. There were 54 women and 48 men. Eighty-six percent of patients with normal facial function preoperatively retained normal function (House score 1 or 2) postoperatively. Of the 64 patients with a functional cochlear nerve preoperatively, five had normal hearing (PTA < 25 dB, SB > 70%), five had near normal hearing (PTA < 45 dB, SD > 70%), four patients had preserved hearing (PTA < 50 dB, SD > 50%), and three patients had preserved cochlear nerve function (PTA > 50 dB, SD < 50%) after surgery. Hearing preservation was obtained in patients whose tumors were larger than 3 cm. Radiological follow-up revealed 10 patients with recurrent tumor, all but one asymptomatic. 相似文献

Evaluation of children and young adults with tethered spinal cord syndrome. Utility of spinal and scalp recorded somatosensory evoked potentials 总被引:5,自引:0,他引:5
The diagnosis of tethered spinal cord syndrome should be considered in young patients with progressive orthopedic deformities, lower extremity weakness, urinary and fecal incontinence, low back pain, or combinations of these symptoms. Myelographic, computed tomographic, and urodynamic studies are useful for establishing a diagnosis, but contribute little to the evaluation of lower extremity sensory function or to the assessment of electrophysiologic impairment of the spinal cord itself. To determine the diagnostic usefulness of the somatosensory evoked potential after posterior tibial nerve stimulation (posterior tibial nerve somatosensory evoked potential) in tethered spinal cord syndrome, 22 consecutive patients with symptoms of tethered spinal cord syndrome (aged 18 months to 22 years) underwent recording of posterior tibial nerve somatosensory evoked potential; results were correlated with clinical, myelographic, and operative findings. In patients with clinical symptoms but no myelographically demonstrable lesions, posterior tibial nerve somatosensory evoked potentials were within normal limits, suggesting normal physiologic function. In patients with myelographically and operatively confirmed tethering dysraphic lesions, posterior tibial nerve somatosensory evoked potential was predictive of the level and laterality of the lesion. Similarly, ranking the severity of neurological impairment and extent of dysraphism at operation, as well as the extent of abnormality of posterior tibial nerve somatosensory evoked potential, revealed a significant (r = 0.81, p less than 0.001) correlation between clinical severity and posterior tibial nerve somatosensory evoked potential abnormalities. Postoperatively, in 8 patients, posterior tibial nerve somatosensory evoked potential also reflected improved function in relation to the level and type of dysraphic lesion present. These findings indicate that posterior tibial nerve somatosensory evoked potential is a sensitive indicator of neurophysiologic status in patients with tethered spinal cord, and is useful for determining the level of the conus medullaris, degree of spinal cord displacement, and severity of neurological impairment associated with this congenital disturbance of neuraxis formation. Recording of posterior tibial nerve somatosensory evoked potential is noninvasive and offers a more sensitive diagnostic tool than the clinical testing of sensation for detection of the development of neurologic deficits in patients with tethered cord syndrome. 相似文献

How should one treat iatrogenic ulnar injury after closed reduction and percutaneous pinning of paediatric supracondylar humeral fractures? 总被引:1,自引:0,他引:1
OBJECTIVE: The purpose of this study was to assess iatrogenic ulnar nerve injuries after supracondylar humeral fractures treated with closed reduction and percutaneous pinning. METHODS: The series consisted of 473 children. All patients were treated with closed reduction and percutaneous pinning. Neurological examination performed immediately after the operation revealed 25 ulnar nerve injuries (5.2%) in patients who had completely normal neurological findings in the preoperative period. Electromyographic examinations were performed at 6 and 12 weeks postoperatively in patient with ulnar nerve lesions. RESULTS: The mean age was 6 years (4-8 years). The mean hospitalisation time was 2 days and the mean follow-up time was 30.8 months (17-63 months). Twenty-two patients with electromyogram showed partial denervation and conduction blocks at the elbow at 6 weeks. Regenerative electromyogram findings were found at 12 weeks. Sensory function in all patients had returned at a mean of 2 months (1-4 months) while motor function had returned at a mean of 5.4 months (1-7 months). Unusually all patients had complete return of nerve function and full motion in their elbows. CONCLUSION: We evaluated the results of 473 patients and to our knowledge this is the largest series in the literature. Although the rate of ulnar nerve injuries (5.2%) is comparable, the number of the patients (n: 22) is the largest in the literature and may allow us to draw stronger conclusions. In our opinion, if ulnar nerve injury is detected after the operation, patients should be followed up for 7 months without intervention. 相似文献

A comprehensive analysis of 187 patients (78 median, 86 ulnar, and 23 radial nerve lesions) treated by an interfascicular autogenous nerve grafting technique is presented. After a follow-up of at least 18 months good motor recovery was achieved in 72% of median nerve lesions, 77% of ulnar nerve lesions, and 57% of radial nerve lesions. Good functional sensory recovery was found in 36% of median, 45% of ulnar, and 48% of radial nerve lesions. It appears by multivariate analysis that the results obtained generally were better in younger patients, in patients with a shorter preoperative delay, and in cases with a shorter transplant. 相似文献
