1/43. Nonunion of a pediatric lateral condyle fracture without ulnar nerve palsy: sixty-year follow-up.Displaced lateral condyle fractures in the pediatric population are usually treated with open reduction and internal fixation. Significant complications associated with the nonoperative management include nonunion, malunion, deformity, and tardy ulnar nerve palsy. However, few cases of nonunion of the lateral condyle and tardy ulnar nerve palsy with long-term follow-up have been reported. We present a radiographically documented case of a pediatric lateral condyle fracture and subsequent nonunion with significant cubitus valgus deformity without ulnar nerve palsy sixty years following injury.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/43. Extracranial vertebral artery dissection causing cervical root lesion.The authors report an unusual manifestation of extracranial vertebral artery dissection (VAD), presenting with a predominantly motor radicular manifestation. Cervical magnetic resonance imaging (MRI) revealed the intramural hematoma in the dissected vessel wall, compressing mainly the segmental motor root and, to a lesser degree, the sensory ganglion. In the digital subtraction angiography (DSA), a circumscribed narrowing of the incriminated vessel was demonstrated. color-coded Duplex imaging (CDDI) revealed complete recanalization after a few days of anticoagulation treatment. Complete neurologic recovery was seen after 3 months. Considering the MRI data, the likely pathogenetic mechanism was compression of the nerve root by the intramural hematoma. The synopsis with similar cases in the literature points to the characteristic features, i.e., the association of neck pain with radicular motor deficit and the absence of degenerative disk disease. The respective syndrome should raise the suspicion of vertebral artery dissection, especially in young individuals.- - - - - - - - - - ranking = 0.76590632670414keywords = compression (Clic here for more details about this article) |
3/43. Neuropraxia of the cervical spinal cord following cervical spinal cord trauma: a report of five patients.Neuropraxia of the cervical spinal cord is a rare condition which is almost exclusively reported in American football players following cervical hyperextension or hyperflexion trauma. In this entity-neurological symptoms of both arms and legs for a period of up to 15 minutes are observed with complete recovery. We report the characteristics of five patients not involved in contact sport activities with a neuropraxia of the spinal cord following cervical trauma. In four of the five patients, this syndrome was associated with a cervical canal stenosis. Surgical decompression was performed in two patients with progressive neurological symptoms after an initial period of recovery. The cases illustrates that although neuropraxia of the spinal cord is usually seen in athletes, also other persons may be at risk for developing this condition, especially when a preexisting spinal stenosis is present. patients who experienced neuropraxia of the spinal cord should thus be evaluated carefully for the presence of cervical spinal cord abnormalities.- - - - - - - - - - ranking = 0.76590632670414keywords = compression (Clic here for more details about this article) |
4/43. hypertension, hyperekplexia, and pyramidal paresis due to vascular compression of the medulla.MRI showed impingement of the vertebral artery on the left lateral medulla in two patients with arterial hypertension, exaggerated startle reflexes (hyperekplexia), and progressive spastic paresis. One patient underwent microvascular decompression with normalization of arterial hypertension, disappearance of hyperekplexia, and improvement of spastic paresis. The combination of arterial hypertension, hyperekplexia, and progressive spastic paresis should arouse suspicion of neurovascular compression of the lateral medulla.- - - - - - - - - - ranking = 4.5954379602248keywords = compression (Clic here for more details about this article) |
5/43. Pyogenic vertebral osteomyelitis presenting as single spinal compression fracture: a case report and review of the literature.STUDY DESIGN: A case report of pyogenic vertebral osteomyelitis (PVO) presenting as single collapsed vertebral body without narrowing of the intervertebral disc space, and review of the literature. OBJECTIVE: To describe an unusual case of PVO showing atypical radiological change and call attention to this condition so that others may avoid this diagnostic pitfall. SETTING: japan. methods: A 62-year-old diabetic woman with suspected T12 pathological fracture of malignant spinal tumor and neurological involvement received urgent anterior decompression and spinal reconstruction without biopsy. RESULTS: Anterior decompression and spinal reconstruction was performed, but histological examination of the specimen after surgery unexpectedly revealed PVO. The surgery was followed by therapy with antibiotics for 7 months. A follow-up radiograph at 5 years after surgery revealed that solid consolidation has been achieved. CONCLUSIONS: diagnosis of PVO presenting with single spinal compression fracture is very difficult. Although the finding of the high signal intensity in the lesion equal to or higher than that of the cerebrospinal fluid on T2-weighted MR image seemed to be the most reliable diagnostic modality retrospectively, diagnosis of this type of PVO is impossible without histology. A needle biopsy before surgery is strongly recommended.- - - - - - - - - - ranking = 6.361344286929keywords = compression, fracture (Clic here for more details about this article) |
6/43. Traumatic invagination of the fourth and fifth cervical laminae with acute hemiparesis.We describe a patient with traumatic right-sided invagination of two consecutive laminae into the spinal canal. The injury resembled a greenstick fracture and resulted in an acute brown-sequard syndrome. There was also an undisplaced hangman's fracture of the axis vertebra. These injuries were caused by an acute hyperextension and axial compression of the cervical spine. Open reduction and internal fixation of the laminar fractures without fusion was followed by full neurological recovery within six weeks.- - - - - - - - - - ranking = 1.2659063267041keywords = compression, fracture (Clic here for more details about this article) |
7/43. Monocular elevator paresis in neurofibromatosis type 2.A retrospective review of 29 consecutive unselected patients referred for neuro-ophthalmic evaluation after the diagnosis of neurofibromatosis type 2 (NF2) showed that four of them had a monocular elevator paresis. In two of the four MRI demonstrated lesions, presumed to be schwannomas, of the third nerve. These findings indicate that monocular elevator paresis is a common neuro-ophthalmic finding in NF2, which the authors suspect is probably a sign of third nerve infiltration or compression by a schwannoma.- - - - - - - - - - ranking = 0.76590632670414keywords = compression (Clic here for more details about this article) |
8/43. Idiopathic osteonecrosis in an adult with familial protein s deficiency and hyperhomocysteinemia.We describe a 36-year-old man with familial protein s deficiency and homozygosity to the methylene tetrahydrofolate reductase (MTHFR) thermolabile variant who had a stroke followed by an episode of idiopathic osteonecrosis that was successfully managed by surgical core decompression. The patient's symptomatic thrombophilia, as well as that of several of his first-degree relatives who also had thrombotic events, raises the possibility that the thrombophilia was a contributing factor to the development of his osteonecrosis.- - - - - - - - - - ranking = 0.76590632670414keywords = compression (Clic here for more details about this article) |
9/43. brachial plexus paresis associated with fetal neck compression from forceps.Instrumental vaginal deliveries have been associated with higher risks of brachial plexus injuries. The proposed mechanisms involve the indirect association of instrumental deliveries with shoulder dystocia and nerve stretch injuries secondary to rotations of 90 degrees or more. We present a brachial plexus paresis resulting from direct compression of the forceps blade in the fetal neck. A term infant was delivered by a low Kielland forceps rotation. No shoulder dystocia was noted. The immediate neonatal exam revealed an Erb's palsy and an ipsilateral bruise in the lateral aspect of the neck. The paresis resolved during the first day of life. Direct cervical compression of the fetal neck by forceps in procedures involving rotations of the presentation may result in brachial plexus injuries.- - - - - - - - - - ranking = 4.5954379602248keywords = compression (Clic here for more details about this article) |
10/43. Phrenic paresis and respiratory insufficiency associated with cervical spondylotic myelopathy.Cervical spondylotic myelopathy is a common disease caused by chronic segmental compression of the spinal cord. Despite the fact that the columns of the nuclei of the phrenic nerve are located between the 3rd and 5th cervical nerve segments, phrenic nerve paresis is not usually clinically significant. We present one case of cervical spondylotic myelopathy with bilateral phrenic paresis in whom magnetic resonance imaging and surgical findings confirmed intrinsic cord disease as being the cause of this syndrome. This case report suggests that one pathophysiology of clinical phrenic nerve paresis may be segmental damage to the anterior horns caused by cervical spondylosis.- - - - - - - - - - ranking = 0.76590632670414keywords = compression (Clic here for more details about this article) |
