1/22. Long-term sequelae after surgery for orbital floor fractures.A surgical technique involving exact repositioning and rigid fixation is required for the reduction of fractures of the orbital floor. Even then, sequelae may be present long after the trauma. The aim of this study was to establish the frequency and type of sequelae after surgery for orbital floor fractures and to investigate the extent to which the method of surgery had any impact on the severity of the sequelae. A questionnaire was sent to all 107 patients (response rate 77%) 1 to 5 years after the injury. Further clinical data were obtained from the patients' charts. Eighty-three percent of the patients were affected by some kind of permanent sequelae in terms of sensibility, vision, and/or physical appearance. A high frequency of diplopia (36%) was related to the reconstruction of the orbital floor with a temporary "supporting" antral packing in the maxillary sinus, a technique which has now been abandoned at our department in favor of orbital restoration with sheets of porous polyethylene. Our conclusion is that, because long-term sequelae are common, the surgical technique must be subjected to continuous quality control to minimize future problems for this group of patients.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/22. cauda equina syndrome due to lumbosacral arachnoid cysts in children.We describe the clinical, neuroradiological and surgical aspects of two children in whom symptoms attributable to cauda equina compression were caused by spinal arachnoid cysts. The first patient presented with recurrent urinary tract infections due to neurogenic bladder dysfunction, absent deep tendon reflexes and sensory deficit in the lower limbs. The second child presented with unstable gait as a result of weakness and diminished sensation in the lower extremities. Spinal magnetic resonance imaging revealed a lumbosacral arachnoid cyst in both patients. During surgery the cysts were identified and excised. Two years after surgery, the sensory deficits of the first patient have disappeared and patellar and ankle reflexes can be elicited, but there is no improvement in bladder function. Neurological examination of the second patient was normal. We conclude that the diagnosis of cauda equina syndrome should prompt a vigorous search for its aetiology. Lumbosacral arachnoid cysts are a rare cause of cauda equina syndrome in children.- - - - - - - - - - ranking = 1.318320545763keywords = compression (Clic here for more details about this article) |
3/22. Bilateral median nerve compression at the level of Struthers' ligament. Case report.Struthers' ligament syndrome is a rare cause of median nerve entrapment. Bilateral compression of the median nerve is even more rare. It presents with pain, sensory disturbance, and/or motor function loss at the median nerve's dermatomal area. The authors present the case of a 21-year-old woman with bilateral median nerve compression caused by Struthers' ligament. She underwent surgical decompression of the nerve on both sides. To the authors' knowledge, this case is the first reported bilateral compression of the median nerve caused by Struthers' ligament. The presentation and symptomatology of Struthers' ligament syndrome must be differentiated from median nerve compression arising from other causes.- - - - - - - - - - ranking = 11.864884911867keywords = compression (Clic here for more details about this article) |
4/22. Electrophysiological analysis of pudendal neuropathy following traction.Pudendal neuropathy is an unusual but important complication of orthopedic surgical procedures involving traction on the fracture table. We describe the clinical and electrophysiological features in six patients presenting with perineal sensory disorders and sexual dysfunction following surgical repair of femoral fracture, hip dislocation, or intra-articular foreign body, in which the traction table was used. All underwent electrophysiological recordings: bulbocavernosus muscle electromyography (EMG), measurements of the bulbocavernosus reflex latencies (BCRLs), somatosensory evoked potentials of the pudendal nerve (SEPPNs), sensory conduction velocity of the dorsal nerve of the penis (SCVDNP), and pudendal nerve terminal motor latencies (PNTMLs). Signs of denervation localized to the territory of the pudendal nerve were found in 3 patients, normal BCRL in 6, abnormal SEPPNs in 4, and abnormal SCVDNPs and PNTMLs in all cases. The outcome at 2-year follow-up was good, except in one patient with initially unrecordable PNTML. Perineal electrophysiological examination can thus confirm the pudendal neuropathy and give prognostic information.- - - - - - - - - - ranking = 0.33333333333333keywords = fracture (Clic here for more details about this article) |
5/22. Neuropathic complications of mandibular implant surgery: review and case presentations.Injuries to trigeminal nerves during endosseous implant placement in the posterior mandible appear to occur acutely in approximately 5-15 of cases, with permanent neurosensory disorder resulting in approximately 8%. Nerve lateralization holds even higher risks from epineurial damage or ischaemic stretching. Neuropathy from implant compression and drill punctures can result in neuroma formation of all types, and in some cases precipitate centralized pain syndrome. Two patterns of clinical neuropathy are seen to result; hypoaesthesias with impaired sensory function, often seen with phantom pain, and hyperaesthesias with minimal sensory impairment but presence of much-evoked pain phenomena. The clinician must differentiate, through careful patient questioning and stimulus-response testing, those patients who are undergoing satisfactory spontaneous nerve recovery from those who are developing dysfunctional or dysaesthetic syndromes. Acute nerve injuries are treated with fixture and nerve decompression and combined with supportive anti-inflammatory, narcotic and anti-convulsant therapy. Surgical exploration, neuroma resection and microsurgical repair, with or without nerve grafting, are indicated when unsatisfactory spontaneous sensory return has been demonstrated, and in the presence of function impairment and intractable pain.- - - - - - - - - - ranking = 2.6366410915261keywords = compression (Clic here for more details about this article) |
6/22. Fourth nerve palsy, homonymous hemianopia, and hemisensory deficit caused by a proximal posterior cerebral artery aneurysm.A 21-year-old man developed an ipsilateral fourth nerve palsy, contralateral hemianopia, and contralateral hemisensory deficit as manifestations of a proximal right posterior cerebral artery aneurysm. This unusual constellation of signs reflects the involvement of the structures that run in the ambient cistern. The fourth nerve palsy and homonymous hemianopia are attributed to compression by the aneurysm. The hemisensory loss is ascribed to compromise of thalamoperforate arteries emanating from a thrombosed portion of the aneurysm.- - - - - - - - - - ranking = 1.318320545763keywords = compression (Clic here for more details about this article) |
7/22. Extradural spinal cord compression by rheumatoid nodule.Rheumatoid disease is a systemic disorder affecting multiple organs. It is known to affect the nervous system in a variety of ways, but its presentation with spinal cord compression by a rheumatoid nodule is rare. We report two cases presenting with cord compression by a rheumatoid nodule who underwent surgical decompression with good recovery.- - - - - - - - - - ranking = 9.2282438203413keywords = compression (Clic here for more details about this article) |
8/22. A spinal neurenteric cyst presenting as burning feet syndrome.Spinal neurenteric cysts are rare congenital cysts of endodermal origin. A 34-year-old man presented with burning feet syndrome lasting two years. Magnetic resonance imaging (MRI) revealed an intradural extramedullary cystic mass extending from L2 to L5 causing severe compression of the terminal portion of the conus medullaris and the filum terminale with displacement to the right side. A tethered cord and filar lipoma were also present. The cystic mass and filar lipoma were resected and the tethered cord released. Histopathology confirmed a neurenteric cyst. This case is reported in view of its peculiar presentation.- - - - - - - - - - ranking = 1.318320545763keywords = compression (Clic here for more details about this article) |
9/22. Cervical disc herniation producing brown-sequard syndrome: case report.BACKGROUND: brown-sequard syndrome is an incomplete spinal cord lesion characterized by a clinical picture reflecting hemisection of the spinal cord in the cervical or thoracic region. brown-sequard syndrome may be the result of penetrating injury to the spine, but many other etiologies have been described. In particular, cervical disc herniation has been rarely reported as a cause of this syndrome, and including the first article of Stookey in 1928, 9 only 22 cases have been reported. methods: The case of a man with a large left paramedian C5-C6 disc herniation, with ipsilateral spinal cord compression, is reported. An area of left-sided spinal cord hyperintensity was also present on MRI, an expression of left hemicord damage. Microdiscectomy and anterior cervical fusion with carbon fiber cage containing a core of granulated coralline hydroxylapatite was performed. A complete motor deficit recovery and a marked sensitive deficit improvement was obtained. CONCLUSION: A critical review of the pertinent literature is proposed, and the neuroradiologic, therapeutic, and prognostic implications are discussed. brown-sequard syndrome produced by a cervical disc herniation is presumably often underdiagnosed, and early surgical intervention is always recommended.- - - - - - - - - - ranking = 1.318320545763keywords = compression (Clic here for more details about this article) |
10/22. Weber's syndrome and sixth nerve palsy secondary to decompression illness: a case report.We describe the first case of Weber's Syndrome to present as a manifestation of decompression illness in a recreational scuba diver. Weber's Syndrome is characterized by the presence of an oculomotor nerve palsy and contralateral hemiparesis. The patient was a 55 year-old male with a past medical history of a pulmonary cyst, in whom symptoms developed after a multilevel drift dive to a depth of 89 feet for 53 minutes, exceeding no-decompression limits. Symptom onset was within 30 minutes of surfacing and included the Weber's Syndrome, a sixth nerve palsy, dizziness, nausea, sensory loss, and ataxia. The patient received four U.S. Navy Treatment tables with complete resolution of all neurological signs and symptoms. The mechanism of injury remains unclear, but may involve aspects of both air gas embolism and decompression sickness. Individuals with pre-existing pulmonary cysts may be at increased risk for dive-related complications.- - - - - - - - - - ranking = 9.2282438203413keywords = compression (Clic here for more details about this article) |
