1/204. An uncommon mechanism of brachial plexus injury. A case report.PURPOSE: To report a case of brachial plexus injury occurring on the contralateral side in a patient undergoing surgery for acoustic neuroma through translabrynthine approach. CLINICAL FEATURES: A 51-yr-old woman underwent surgery for acoustic neuroma through translabrynthine approach in the left retroauricular area. She had a short neck with a BMI of 32. Under anesthesia, she was placed in supine position with Sugita pins for head fixation. The head was turned 45 degrees to the right side and the neck was slightly flexed for access to the left retroauricular area, with both arms tucked by the side of the body. Postoperatively, she developed weakness in the right upper extremity comparable with palsy of the upper trunk of the brachial plexus. hematoma at the right internal jugular vein cannulation site was ruled out by CAT scan and MRI. The only remarkable finding was considerable swelling of the right sternocleidomastoid and scalene muscle group, with some retropharyngeal edema. An EMG confirmed neuropraxia of the upper trunk of brachial plexus. She made a complete recovery of sensory and motor power in the affected limb over the next three months with conservative treatment and physiotherapy. CONCLUSIONS: brachial plexus injury is still seen during anesthesia despite the awareness about its etiology. Malpositioning of the neck during prolonged surgery could lead to compression of scalene muscles and venous drainage impedance. The resultant swelling in the structures surrounding the brachial plexus may result in a severe compression.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/204. Transient peroneal nerve palsies from injuries placed in traction splints.Two patients thought to have distal femur fractures presented to the emergency department (ED) of a level 1 trauma center with traction splints applied to their lower extremities. Both patients had varying degrees of peroneal nerve palsies. Neither patient sustained a fracture, but both had a lateral collateral ligament injury and one an associated anterior cruciate ligament tear. One patient had a sensory and motor block, while the other had loss of sensation on the dorsum of his foot. After removal of the traction splint both regained peroneal nerve function within 6 hours. Although assessment of ligamentous knee injuries are not a priority in the trauma setting, clinicians should be aware of this possible complication in a patient with a lateral soft tissue injury to the knee who is placed in a traction splint that is not indicated for immobilization of this type of injury.- - - - - - - - - - ranking = 0.93802045683524keywords = fracture (Clic here for more details about this article) |
3/204. Post-traumatic distal nerve entrapment syndrome.Eleven patients with paralysis of muscle groups in the upper or lower extremity were clinically diagnosed after previous proximal direct trauma to the corresponding peripheral nerves, without complete nerve disruption. patients were seen within an average of 8 months after trauma (minimum 3 months and maximum 2 years after). Nerve lesions were caused either by gunshot, motor-vehicle accident, and other direct trauma or, in one case, after tumor excision. All patients presented with complete sensory and motor loss distal to the trauma site, but demonstrated a positive Tinel sign and pain on testing over the "classic" (distal) anatomic nerve entrapment sites only. After surgical release through decompression of the nerve compression site distal to the trauma, a recovery of sensory function was achieved after surgery in all cases. Good-to-excellent restoration of motor function (M4/M5) was achieved in 63 percent of all cases. Twenty-five percent had no or only poor improvement in motor function, despite a good sensory recovery. Those patients in whom nerve compression sites were surgically released before 6 months after trauma had an improvement in almost all neural functions, compared to those patients who underwent surgery later than 9 months post trauma. A possible explanation of traumatically caused neurogenic paralysis with subsequent distal nerve compressions is provided, using the "double crush syndrome" hypothesis.- - - - - - - - - - ranking = 2keywords = compression (Clic here for more details about this article) |
4/204. Anterior interosseous nerve compression after supracondylar fracture of the humerus: a metaanalysis.OBJECT: The authors conducted a metaanalysis of reports of anterior interosseous nerve syndrome, a rare nerve compression neuropathy that affects only the motor branch of the median nerve. This syndrome is characterized by paralysis of the flexor pollicis longus, the flexor digitorum profundus to the index finger, and the pronator quadratus, with weakness on flexion of the interphalangeal joint of the thumb and the distal interphalangeal joint of the index finger without sensory loss. methods: The authors reviewed reports of 34 cases of anterior interosseous nerve syndrome combined with supracondylar fractures of the humerus in children. They have added a new case identified in a 7-year-old boy in whom a diagnosis was made from the clinical findings and whose treatment and outcome are analyzed. The ages of patients reported in the literature ranged from 4 to 10 years. Ten patients (29%) were treated with closed reduction and application of a cast, whereas 25 patients (71%) were treated with open reduction and fixation of the fracture. CONCLUSIONS: All patients regained full flexion and strength after 4 to 17 weeks. The fractures that were surgically treated showed no entrapment of the anterior interosseous nerve.- - - - - - - - - - ranking = 5.7830715989233keywords = compression, fracture (Clic here for more details about this article) |
5/204. Posterior interosseous nerve palsy in a patient with rheumatoid synovitis of the elbow: a case report and review of the literature.A 54-year-old woman with rheumatoid arthritis developed loss of finger extension in the left hand. history, physical examination, and electromyography led to the diagnosis of posterior interosseous nerve palsy secondary to synovitis of the elbow. Anterior decompression and synovectomy resulted in a complete recovery.

6/204. Unusual cranial nerve palsy caused by cavernous sinus aneurysms. Clinical and anatomical considerations reviewed.BACKGROUND: Two cases of intracavernous internal carotid artery aneurysm with unusual clinical findings are reported. The pathomechanism and clinical significance are discussed. CASE DESCRIPTION: The first patient was a 49-year-old woman who presented with 6th nerve palsy and Horner's syndrome caused by a posteriorly located intracavernous aneurysm. The symptoms improved gradually in proportion to the size of the aneurysm. The second patient was a 69-year-old woman with isolated oculomotor superior division palsy caused by an anteriorly located large aneurysm. CONCLUSION: In the first case, a local aneurysmal compression at both the 6th nerve and the sympathetic fibers sent from the plexus on the intracavernous internal carotid artery is the most probable explanation. In the second case, the aneurysm might have selectively compressed the superior division of the oculomotor nerve at the anterior cavernous sinus. Clinical recognition of these syndromes results in a better diagnostic orientation. The authors discuss the pertinent anatomy and pathophysiology of the lesions because these findings are rarely seen clinically or in the literature.- - - - - - - - - - ranking = 0.5keywords = compression (Clic here for more details about this article) |
7/204. Newborn radial nerve palsy: report of four cases and review of published reports.Four newborns presented with isolated radial nerve palsy during the first 2 days of life. In three, there was a history of failure of progression of labor, which may have resulted in prolonged radial nerve compression. Furthermore, three infants had fat necrosis of the upper arm above the elbow, suggestive of compression of the radial nerve in the region of the spiral groove. Significant recovery of function was evident within 1 month in all four infants. The authors review published reports about the rare condition of isolated radial nerve palsy in the newborn.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
