Thirteen patients who underwent occipitocervical fusion that was performed using the same operative technique were followed for an average of 3.6 years (range, two to seven years). The indications for surgery were occipitocervical instability, neurological deficit, or intractable pain that was not responsive to non-operative treatment. Of the thirteen patients, eight had rheumatoid arthritis, two had atlanto-axial osteomyelitis, and one patient each had trauma, ankylosing spondylitis, and atlanto-occipital osteoarthritis. At follow-up, all of the thirteen patients had a solid arthrodesis and relief of severe pain in the neck. Of the ten patients who had had myelopathy preoperatively, all improved, but of four patients who had been unable to walk preoperatively because of severe motor involvement, only one was considered to be able to walk. Of the thirteen patients, ten had a satisfactory result. Occipitocervical arthrodesis using iliac grafts and the wiring technique that is described herein achieves immediate stable fixation, allowing early mobilization with a successful arthrodesis, and it should be undertaken before severe myelopathy occurs in patients who have instability of the cervical spine. The operation may optimize the patient's chances of neurological recovery.

A patient with ankylosing spondylitis sustained C3-C4 vertebral subluxation and C4-C5 myelopathy after a hyperextension trauma. Autopsy showed that several segments below the main cervical cord lesion at the fractured site, there was a second spinal cord lesion at the T1 vertebral level with no corresponding local bony or ligamentous damage. The thoracic cord lesion was probably secondary to traction of the upper thoracic cord, where the blood supply is poor, in a narrow and rigid spinal canal at the moment of extreme hyperextension.

Neck pain may affect one third of the adult population from time to time and may persist for 6 months or longer in 10% to 15% of these patients. In addition, cervical spine disease or trauma may result in injury to the spinal cord or nerve roots, through a variety of mechanisms, leading to a group of syndromes that can be broadly classified as myelopathy or radiculopathy. This review addresses recent developments in the anatomy and physiology of the normal cervical spine, common ill-defined or miscellaneous neck pain problems, and cervical injuries, with emphasis on the flexion-extension injury called "whiplash." Other types of injuries, including fractures and fracture dislocations, also are discussed, as well as neurologic consequences of cervical disk and facet joint degenerative disease, with emphasis on cervical spondylitic myelopathy. The complications of inflammatory joint diseases such as ankylosing spondylitis and rheumatoid arthritis are not specifically addressed in this review.

Ossification of the posterior longitudinal ligament (OPLL) may be associated with certain rheumatic conditions including ankylosing spondylitis (AS), diffuse idiopathic skeletal hyperostosis (DISH) or spondylosis. More than 95% of all OPLL are localized at the cervical spine. Herein, we report a case of OPLL at the thoracic spine in an HLA-B27-positive female patient with ankylosing spondylitis. The patient was presented to use with spastic paraparesis. The imaging studies included plain roentgenograms, tomograms, myelo-CT and magnetic resonance imaging (MRI). A continuous rod-like ossification along the posterior aspects of the fourth to sixth thoracic vertebrae with spinal cord compression was noted. The patient underwent a laminectomy from T4 to T6. At the second year follow-up examination, residual upper back soreness and mild left thigh pain were noted. However, the patient had resumed a full daily schedule and could walk freely without any support.

The aim of this paper is to review the incidence and characteristics found in traumatic spinal cord injury (SCI) occurring in patients with long-standing ankylosing spondylitis (AS). The incidence of patients with traumatic SCI admitted to our unit from January 1984 to February 1996 was 2% (15 out of 893). They were all men with a mean age of 56 years. Most frequently the etiology of the lesion was a motor vehicle accident and the injury was mainly due to a hyperextension mechanism. Acute spinal fracture occurred in 13 patients, all involving the cervical region. No fracture was observed in two patients with thoracic neurological level. Three patients presented with an interval free period of neurological symptoms in whom a spinal epidural hematoma was visualized with magnetic resonance imaging. On admission eight patients were diagnosed as having complete SCI and the other seven an incomplete SCI. In the acute phase, respiratory complications were most frequent, causing six patients to die. Treatment was conservative in 14 patients. Multidisciplinary management of these patients should be implemented in an institution equipped with both a Spinal Injury Unit and an Intensive Care Unit.

Ankylosing Spondylitis can be associated with extra-articular involvement. Besides internal and ocular complications, neurological manifestations such as single root lesions, compression of the myelum or the cauda equina syndrome have also been described. We present a patient with ankylosing spondylitis who developed a monophasic myelopathy resembling multiple sclerosis. Literature data show no conclusive evidence for an increased association of ankylosing spondylitis and multiple sclerosis. However, a monophasic myelopathy may be a separate neurological manifestation associated with ankylosing spondylitis.

Ankylosing spondylitis patients are more prone to spinal fractures and these fractures commonly result in mobile nonunion. We report a patient with a 30-year history of ankylosing spondylitis who sustained double spinal cord injuries following minor trauma. The first injury occurred at the lumbar level due to pseudoarthrosis of an old fracture, and the second at the thoracic level following cardiopulmonary arrest and an episode of hypotension. The possible mechanisms of the injuries are discussed and maintaining normal blood pressure in these patients is emphasized.

Patients with ankylosing spondylitis are prone to fractures. We describe a 32-year-old male patient with an odontoid fracture and anterior dislocation of C1 vertebra relative to C2 complicating ankylosing spondylitis. The importance and difficulties of the rehabilitation program are stressed. The role of magnetic resonance imaging and three-dimensional computerized tomography in diagnosis is emphasized.

Forestier's disease now called DISH (diffuse idiopathic skeletal hyperostosis) is a non inflammatory enthesopathy ossifying the anterolateral spine and sparing the disc and joint space in elderly men, mostly at thoracic levels. Radiology performed for minor trauma or to explore a stiff neck provides the diagnosis. The main differential diagnosis is ankylosing spondylitis presenting an inflammatory profile as well as previously existing alterations of the sacroiliac joint. Retinoic acid treatment or ossification of the posterior longitudinal ligament should also be discussed. Dysphagia is the most frequent symptom, but neurological signs are rarely observed. We report a case observed at the cervical level. Anterior decompression and cage-fusion was indicated. Ongoing hyperostosis was also documented. Surgery in DISH is mainly indicated for dysphagia and rarely after cervical trauma. Of note are associated lesions such as OPLL (ossification of the posterior longitudinal ligament) or synovial cysts responsible for the exceptional and severe myelopathy presentation. The neurosurgical community should become better aware of Forestier's disease.

Studies examined the neurological involvement of ankylosing spondylitis (AS) are limited. This study aimed to assess the frequency of myelopathy, radiculopathy and myopathy in AS correlating them to the clinical, radiological and laboratory parameters. Included were 24 patients with AS. Axial status was assessed using bath ankylosing spondylitis metrology index (BASMI). Patients underwent (a) standard cervical and lumbar spine and sacroiliac joint radiography, (b) somatosensory (SSEP) and magnetic motor (MEP) evoked potentials of upper and lower limbs, (c) electromyography (EMG) of trapezius and supraspinatus muscles. Patients' mean age and duration of illness were 36 and 5.99 years. Bath ankylosing spondylitis metrology index mean score was 4.6. Twenty-five percent (n = 6) of patients had neurological manifestations, 8.3% of them had myelopathy and 16.7% had radiculopathy. Ossification of the posterior (OPLL) and anterior (OALL) longitudinal ligaments were found in 8.3% (n = 2) and 4.2% (n = 1). About 70.8% (n = 17) had >or=1 neurophysiological test abnormalities. Twelve patients (50%) had SSEP abnormalities, seven had prolonged central conduction time (CCT) of median and/or ulnar nerves suggesting cervical myelopathy. Six had delayed peripheral or root latencies at Erb's or interpeak latency (Erb's-C5) suggesting radiculopathy. Motor evoked potentials was abnormal in 54% (n = 13). Twelve (50%) and five (20.8%) patients had abnormal MEP of upper limbs and lower limbs, respectively. About 50% (n = 12) had myopathic features of trapezius and supraspinatus muscles. Only 8.3% (n = 2) had neuropathic features. We concluded that subclinical neurological complications are frequent in AS compared to clinically manifest complications. Somatosensory evoked potential and MEP are useful to identify AS patients prone to develop neurological complications.
