Lumbar spinal stenosis and diabetes. Outcome of surgical decompression.
We reviewed 25 diabetic (mean age 68 years) and 25 non-diabetic patients (mean age 71 years) who had undergone decompression for lumbar spinal stenosis at a mean of 3.4 years after operation to determine whether diabetes affected the outcome of surgery. The preoperative symptoms were similar in the two groups except that an abrupt onset of symptoms, the presence of night pain and the absence of any posture-related pain relief were recorded only by diabetic patients. Nerve-conduction velocity was slowed in 80% of the diabetic and in 25% of the non-diabetic patients. Peripheral vascular deficiency was diagnosed in 20% of patients with diabetes and in 4% of non-diabetics. The outcome of surgery was similarly successful in the two groups. Mistaken preoperative diagnosis was the cause of failure in three diabetic patients, two with diabetic neuropathy and one with diabetic angiopathy.
