[Postoperative lumbar intervertebral discitis. A review of a 15-year period and 7,493 operations].

The incidence of postoperative discitis in a series of almost 7500 surgical interventions covering a period of 15 years is reported. Ninety patients (1.2%) were found to be suffering from typical symptoms, which are described and discussed. It is pointed out that above all radicular pain diminished, while on the other hand severe pain occurred in the lumbar spine, caused by movement and vibration, accompanied by a usually sharp rise in ESR, up to values of 100/200 mm. It is pointed out that conventional tomography is the diagnostic tool of choice, diagnosis being possible as of approx. three weeks postoperatively. The social implications of this important complication are pointed out, in particular the fact that only 50% of patients were able to return to full-time work in their old occupations, while the rest had to retire or accept a less strenuous job.
