Aims

The aim of this study was to use diffusion tensor imaging (DTI) to investigate changes in diffusion metrics in patients with cervical spondylotic myelopathy (CSM) up to five years after decompressive surgery. We correlated these changes with clinical outcomes as scored by the Modified Japanese Orthopedic Association (mJOA) method, Neck Disability Index (NDI), and Visual Analogue Scale (VAS).

We describe an unusual injury to the upper cervical spine sustained during ejection from an aircraft. MRI provided an accurate and direct diagnosis of the severe ligamentous injuries

Radiographic examination of a giraffe-necked woman shows that there is no true elongation of the cervical spine. The apparent lengthening of the neck is due to incorporation of part of the thoracic spine and thorax in the neck

1. A patient is described who developed hypothermia shortly after being rendered tetraplegic by a fracture of the cervical spine. 2. The causes and prevention of hypothermia or hyperpyrexia in tetraplegia are discussed

1. A case of cervical cord compression due to a congenital anomaly of the arch of the axis, treated successfully by decompressive laminectomy twenty-six years after the onset of symptoms, is described. 2. The significance of bony abnormalities of the cervical spine as a treatable cause of spastic tetraparesis is stressed

Injury to the spinal cord without radiological abnormality often occurs in the skeletally immature cervical and thoracic spine. We describe four adult patients with this diagnosis involving the cervical spine with resultant quadriparesis. The relevant literature is reviewed. The implications for initial management of the injury, the role of MRI and the need for a high index of suspicion are highlighted

1. The "halo" traction apparatus and its method of application are described in detail. 2. Its use in nine patients with subluxation or fracture-dislocation of the cervical spine, and in one patient with extensive vertebral disease, is recorded. 3. The indications for using the "halo" traction apparatus are outlined

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-Séquard 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

We report three patients having transoral fusion at C2/3 or C3/4 after fractures, with no infections or surgical complications and sound union. The operative technique and the relative merits of different approaches to the upper cervical spine are discussed and the transoral approach to the anterior aspect of the upper three cervical vertebrae is commended to the specialist surgeon

1. The literature on paraplegia complicating hyperextension injuries of the cervical spine is reviewed, and the lack of any definite explanation of the mode of interference with cord function is noted. 2. A case is described in which a detailed dissection of the post-mortem specimen was carried out. On the basis of the findings it is suggested that one cause of the suppression of cord function in such injuries is thrombosis of the spinal arteries and liquefaction-necrosis of the cord

1) A case is reported of paraplegia with normal radiographic appearances in which cervical cord damage was shown at autopsy to have been due to hyperextension injury. 2) The mechanism of such injuries is discussed, together with the differential diagnosis from acute prolapse of an intervertebral disc. 3) The grave dangers of using the fully extended position of the cervical spine in the management of these cases is noted

We reviewed 161 patients, from four centres in Switzerland, who had undergone posterior fusion of the upper cervical spine with transarticular screw fixation of the atlanto-axial joints. They were followed up for a mean 24.6 months. The vertebral artery and the medulla escaped injury and only 5.9% of the complications were directly related to the screws. The rate of pseudarthrosis was 0.6%

1. Four patients with tetraplegia from rheumatoid subluxation occurring in the lower cervical spine are described and the common features are noted. 2. Compression appeared to be responsible for the cord damage, although it was not necessarily directly related to vertebral subluxation. The lesions causing the compression were varied. 3. Forcible attempts to reduce vertebral subluxation may be harmful. Two patients were improved by posterior decompression. 4. A suggested programme for the treatment of such patients is outlined

A review of 77 patients with traumatic central cord syndrome revealed that atypical variations are more common than the existing literature suggests and that these may be seen in a wide variety of acute injuries to the cervical spine. In general the outcome is good; a favourable prognosis on admission is suggested by good hand function, hyperpathia, Lhermitte's sign and normal perianal sensation. The study has highlighted the value of regular muscle charting and has cast doubt on previous neuroanatomical assumptions about the syndrome

Anterior subluxation of the cervical spine from flexion-rotational violence is often overlooked. Either radiography is omitted or the slight displacement visible on the films is not recognised. A method for recognising these injuries is suggested. Five cases are described showing that in these subluxations the soft-tissue damage is severe, that late increasing displacement can occur, with varying neurological sequelae, and that instability can persist indefinitely. Four of the patients required stabilisation by operation, in contrast with complete dislocations in which 80 to 90 per cent fuse spontaneously
