1/31. Spontaneous atlantoaxial rotatory fixation in old age after cerebral infarction: case report.STUDY DESIGN: Case report of spontaneous Fielding and Hawkins Type I atlantoaxial rotatory fixation in a 78-year-old man after hemiplegia and homonymous hemianopsia caused by cerebral infarction. OBJECTIVES: To describe a case of spontaneous atlantoaxial rotatory fixation in old age and review previous adult cases of atlantoaxial rotatory fixation without fracture. SUMMARY OF BACKGROUND DATA: Atlantoaxial rotatory fixation in adults is a relatively rare finding and is mainly caused by trauma. To the author's knowledge, there has been no previous report of spontaneous atlantoaxial rotatory fixation in old age. methods: The patient's head was fixed in a 40 degrees left-rotated position. Left hemiplegia and homonymous left-side hemianopsia developed due to cerebral infarction. Computed tomography of the cervical spine clearly showed rotatory fixation of the atlas on the axis. RESULTS: Successful reduction was obtained after 1 day of skull traction. CONCLUSIONS: It was hypothesized that repeated left-rotational stress due to homonymous hemianopsia loaded to the atlantoaxial joint caused abnormal laxity of the joint.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/31. Spasmodic torticollis due to neurovascular compression of the spinal accessory nerve by the anteroinferior cerebellar artery: case report.OBJECTIVE AND IMPORTANCE: Spasmodic torticollis is a neuromuscular disorder characterized by uncontrollable clonic and intermittently tonic spasm of the neck muscles. We report a case of spasmodic torticollis attributable to neurovascular compression of the right XIth cranial nerve by the right anteroinferior cerebellar artery (AICA). CLINICAL PRESENTATION: A 72-year-old man with a 2-year history of right spasmodic torticollis underwent magnetic resonance imaging, which demonstrated compression of the right XIth cranial nerve by an abnormal descending loop of the right AICA. INTERVENTION: The patient underwent microvascular decompression surgery. During surgery, it was confirmed that an abnormal loop of the right AICA was compressing the right accessory nerve. Compression was released by the interposition of muscle between the artery and the nerve. CONCLUSION: The patient's postoperative course was uneventful, and his symptoms were fully relieved at the 2-year follow-up examination. This is the first reported case of spasmodic torticollis attributable to compression by the AICA; usually, the blood vessels involved are the vertebral artery and the posteroinferior cerebellar artery.- - - - - - - - - - ranking = 5.6356611128808keywords = compression (Clic here for more details about this article) |
3/31. Anomalous vertebral artery-induced cervical cord compression causing severe nape pain. Case report.The authors describe a very rare case of cervical cord compression caused by anomalous bilateral vertebral arteries (VAs). A 65-year-old woman had been suffering from intractable nape pain and torticollis. magnetic resonance imaging revealed a signal void region in which spinal cord compression was present. angiography demonstrated anomalous bilateral VAs compressing the spinal cord. Microvascular decompressive surgery was successfully performed. Neuroradiological and intraoperative findings are presented.- - - - - - - - - - ranking = 4.2267458346606keywords = compression (Clic here for more details about this article) |
4/31. Combined odontoid and jefferson fracture in a child: a case report.STUDY DESIGN: A case of combined odontoid and Jefferson fracture is reported. OBJECTIVE: To alert spine physicians to the rare combination of an odontoid and Jefferson fracture in a child. methods: A 5-year old boy presented with neck pain and torticollis after falling on his head from a four-wheeler that had rolled over. A computed tomography scan confirmed a combined odontoid and Jefferson fracture. RESULTS: The child was successfully treated nonsurgically with a hard cervical orthosis. At this writing, the child clinically is asymptomatic 2 years after the injury. DISCUSSION: The fall on to the head caused the body weight to be transmitted to the atlas. The resulting force vector produced the classic Jefferson fracture of the atlas. As the atlas fracture spread with continued compressive and axial forces, tension was exerted on the alar ligaments (check ligaments), leading to the avulsion fracture of the odontoid. CONCLUSIONS: This is only the second reported case of a child with a combined Jefferson and odontoid fracture. This diagnosis should be considered in the evaluation of a child with neck pain and torticollis from a fall on the top of the head.- - - - - - - - - - ranking = 11keywords = fracture (Clic here for more details about this article) |
5/31. Midshaft clavicle fractures associated with atlantoaxial rotatory displacement: a report of two cases.Two cases of clavicle fractures associated with atlantoaxial rotatory displacement as well as 11 additional cases from the literature are presented. Most cases occur in girls 6 to 10 years old. The head is most often laterally bent toward and rotated away from the fractured clavicle. There is often a delay in making the diagnosis, which is best demonstrated by dynamic CT. Treatment of the clavicle fracture is straightforward, but failure to recognize and treat the C1-2 rotatory displacement promptly can lead to fixed C1-2 deformity. Displacement recognized within the first 3 weeks of injury can be successfully treated nonoperatively. A delay of 6 weeks or greater in the diagnosis leads to fixed deformity at C1-2 that can be addressed with a limited cervical fusion.- - - - - - - - - - ranking = 7keywords = fracture (Clic here for more details about this article) |
6/31. Atlantoaxial rotatory subluxation with ankylosis in an 11-year-old girl: a case report.STUDY DESIGN: Report of an 11-year-old girl with a left atlantoaxial rotatory subluxation and ankylosis found 20 months after she sustained a cervical injury. OBJECTIVE: To describe the radiographic characteristics of this rare deformity assessed with a combination of spiral CT scan with multiplanar three-dimensional reformations and functional CT scan. SUMMARY OF BACKGROUND DATA: Atlantoaxial rotatory subluxation is a well-known condition, but its association with lateral C1-C2 ankylosis has not been reported to our knowledge. methods: For a complete assessment of the dislocation, a combined morphologic volumetric and functional CT study was performed. RESULTS: Spiral CT showed an atlantoaxial rotatory subluxation with lateral C1-C2 ankylosis. CT study also demonstrated a lateral C1-C2 subluxation and an ipsilateral occipitoatlantal subluxation. Cervical MRI showed no spinal cord compression despite the seriousness of the dislocation process. CONCLUSIONS: Whereas "classic" spiral study with multiplanar and three-dimensional reformations allows precise assessment of relationships between the upper cervical vertebrae, as well as bony changes, a functional CT study is essential for cervical biomechanic assessment of rotational instabilities of the craniovertebral junction and upper cervical spine.- - - - - - - - - - ranking = 0.70445763911011keywords = compression (Clic here for more details about this article) |
7/31. Traumatic occipital condyle fracture, multiple cranial nerve palsies, and torticollis: a case report and review of the literature.A 32-year-old man sustained a unique combination of injuries: an occipital condyle fracture, left tenth to twelfth cranial nerve palsies, and chronic torticollis secondary to atlantoaxial rotatory fixation. Computed tomography (CT) demonstrated a triangular fragment of bone in the posterior fossa, and three-dimensional CT-reconstructed images confirmed the bone fragment to be from the occipital condyle. The patient made a good recovery with conservative management. Few occipital condyle fractures have been reported, and they should be suspected in patients who sustain painful neck and lower cranial nerve palsy following trauma. CT and plain films are complementary in confirming the diagnosis.- - - - - - - - - - ranking = 6keywords = fracture (Clic here for more details about this article) |
8/31. Surgical treatment of cervical myeloradiculopathy associated with movement disorders: indications, technique, and clinical outcome.OBJECTIVE: movement disorders may be associated with advanced cervical myeloradiculopathy, which represents a major management challenge. We report on eight patients with movement disorders causing progressive cervical myeloradiculopathy who were treated successfully by cervical decompression and reconstruction. RESULTS: The mean age of our patients was 44 years with a male/female ratio of 3:1. The average duration of symptoms prior to presentation was 10 months. The most common levels decompressed and reconstructed were C3-C4 and C4-C5. Six cases showed improvement, and two cases showed stabilization of neurologic status at a mean follow-up of 21 months. Our management strategy and results are interpreted in the context of a systematic review of the literature in which 78 cases are reported. CONCLUSIONS: movement disorders cause premature cervical spondylosis most commonly involving the C3-C4 and C4-C5 levels. Ventral pathology with kyphotic angulation requires corpectomy or discectomy with or without posterior decompression and reconstruction. Decompression should always be combined with segmental internal fixation. Perioperative use of botulinum toxin and halo vest immobilization can increase the rate of clinical success but requires vigilance to minimize complications. laminectomy with lateral mass fixation may be used successfully in the absence of kyphotic deformity.- - - - - - - - - - ranking = 2.1133729173303keywords = compression (Clic here for more details about this article) |
9/31. Transient tetraplegia and vegetative dysfunction depending on cervical positioning caused by a cervical spinal chordoma.A 39-year-old man with acquired torticollis suffering from cervicobrachialgia and neurological deficits is presented. Due to a change in head position a transient reproducible tetraplegia and severe vegetative dysfunctions were caused. The origin of this uncommon serious combination of symptoms and signs was a chordoma of the upper cervical spine. After surgical decompression the patient was free of neurological deficit and pain. review of the literature did not reveal any similar case.- - - - - - - - - - ranking = 0.70445763911011keywords = compression (Clic here for more details about this article) |
10/31. Traumatic spinal epidural hematoma-unusual cause of torticollis in a child.Traumatic spinal epidural hematoma is rare in children. The presentation could be nonspecific, leading to a delay in diagnosis. We present an infant who sustained an epidural hematoma after a "trivial" injury. The delay in diagnosis led to minor neurological deficit at 6-week follow-up. Irritability and torticollis after a neck trauma in an afebrile child should alert to the possibility of spinal cord compression. Early imaging and early decompression will minimize morbidity.- - - - - - - - - - ranking = 1.4089152782202keywords = compression (Clic here for more details about this article) |
