Chronic contained rupture of an abdominal aortic aneurysm is rare. These aneurysms are small and affected patients are usually normotensive. ⋯ Diagnosis is often delayed as the condition may present with symptoms referable to the lumbar spine. This report is of two cases where the initial diagnosis was infective spondylitis.

Thirty-one consecutive patients with ankylosing spondylitis and spinal fractures were reviewed. There were 6 women and 25 men with a mean age of 60 +/- 11 years; 19 had cervical and 12 had thoracolumbar injuries. Of the patients with cervical fracture, two had an additional cervical fracture and one had an additional thoracic fracture. ⋯ The risk of late neurological deterioration is substantial. As the condition is very rare and the treatment is demanding and associated with a very high risk of complications, the treatment of these patients should be centralised in special spinal trauma units. A combined approach that stabilises the spine from both sides is probably beneficial.

A case of atlantoaxial instability with a rare etiology in a boy of 7 years and 3 months is presented. Computerized tomography with three-dimensional reconstruction revealed avulsion of the ossiculum terminale (apical odontoid epiphysis). ⋯ Temporary posterior C1/C2 fusion and transdental screw fixation of the ossiculum terminale were attempted in order to stabilize C1/C2 and avoid permanent fusion. After removal of the dorsal implants, the transdental screw broke, the instability recurred and a permanent atlantoaxial fusion had to be performed.

Between 1985 and 1990, 68 patients with cervical radiculopathy due to soft disc herniation were treated by anterior cervical discectomy without interbody fusion. Eleven patients were unavailable for follow-up examination. The mean follow-up was 23 months (range 12-54 months). ⋯ No neurologic deficits arose. One patient was reoperated and fused for intractable residual neck pain. We conclude that anterior cervical discectomy without interbody fusion is a simple, safe and effective procedure for patients with soft disc herniation.

Seventy patients with adolescent idiopathic right thoracic scoliosis had full assessment of their pulmonary function using a computerised pulmonary function system. Their mean age at evaluation was 13.8 years. The following measurements were obtained from anteroposterior and lateral standing and antero-posterior supine bending radiographs: lateral curvature, vertebral rotation, kyphosis, maximum sterno-vertebral distance and apical rib-vertebral angles. ⋯ Mean values of Cobb angle, vertebral rotational flexibility, kyphosis, rib-vertebral angle asymmetry (in standing as well as supine bending radiographs) differed significantly between patients with more than 80% of predicted vital capacity and those with 60% or less of predicted values. Radiological features indicative of better pulmonary function were: rotational flexibility exceeding 55%, rib-vertebral angle asymmetry (standing) less than 25 degrees and kyphosis greater than 15 degrees. Two deformity parameters--that give a better prediction of pulmonary function than the widely used Cobb angle, vertebral rotational flexibility and rib-vertebral angle asymmetry--were identified in this study.
