Multiple thoracic spine fractures complicating ankylosing hyperostosis of the spine.

Ankylosing hyperostosis of the spine is a distinct clinical entity that merits diagnosis and recognition of its structural limitations. The case of multiple thoracic spine fractures presented here emphasizes the potentially increased susceptibility of involved spines to trauma and also suggests the need to caution diagnosed patients from placing their spines at undue risk.

Results of surgical intervention in the symptomatic multiply-operated back patient. Analysis of sixty-seven cases followed for three to seven years.

Sixty-seven of seventy-three patients who had had multiple operations on the back with an initial diagnosis of lumbar-disc disease were reevaluated as to relief of pain two and four years after the most recent operation. More than 80 per cent of the patients had gained enough relief to deem the procedure worth while. A diagnosis of fibrosis, preoperatively or intraoperatively, portended a poor result, while the opposite was true with diagnoses of mechanical compression (disc fragment or stenosis) and instability (pseudarthrosis after fusion or spondylolisthesis). The presence of a pain-free interval lasting one year from the date of the previous operation correlated highly with the presence of a surgically remediable lesion.

Concomitant dislocation and intraarticular foreign body: a rare complication of the Charnley total hip arthroplasty.

In the Charnley total hip arthroplasty, periarticular foreign bodies represent potential foci for intraarticular migration at the time of hip dislocation. This complication, although very rare, should be verified radiographically to prevent unsucessful attempts at closed reduction. Although intraarticular radiopaque foreign bodies should be identified on plain radiographs of the hip, intraarticular radiolucent foreign bodies require positive-contrast arthrography for identification. Two illustrative cases are presented.

The acute cervical disk.

Acute cervical disk herniations represent one facet of the broad spectrum of cervical disk degeneration. It is productive of symptoms through mechanical compression and biochemical inflammation of the nerve roots and spinal cord. The majority of patients will respond to a conscientiously applied course of conservative treatment. In those individuals who fail to respond to conservative treatment in terms of pain relief or in whom a significant neurologic deficit occurs surgical decompression of the neural elements should be undertaken.

Low-back pain and sciatica following total hip replacement: a report of two cases.

Two cases of low-back pain and sciatica following total hip replacement are reported. Both patients were operated upon and after lumbar decompression were free of pain. A theory is presented to suggest that the lengthening of the limb after total hip replacement puts excess tension on the spinal nerves and, in conjunction with preexisting degenerative disc disease, will precipitate low-back pain and sciatica.
