The Study: Radiographic predictors of residual low back pain after laminectomy for lumbar canal stenosis: a minimum of 6-year follow-up.
a. The authors wanted to see what predictors for low back pain could be found on x-rays in patients who had undergone laminectomies.
b. The patients had undergone these laminectomies for treatment of lumbar canal stenosis.
c. Residual low back pain is a problem for this type of patient.
d. Decompressive laminectomy for the treatment of lumbar canal stenosis is a common procedure.
e. “It substantially improves symptoms of neurogenic claudication and radiculopathy but” is not as effective for the relief of low back pain.
f. The study looked at 69 patients who suffered from low back pain and pain in either one or both legs.
g. These patients were diagnosed with lumbar canal stenosis and underwent laminectomies.
h. With a 6-year follow up “there are still 28.99% patients suffer from
severe ongoing LBP.”
i. The authors felt that patients who demonstrated “flat back and limited lumbar mobility before surgery tend to have poor results in terms of LBP.”
Patients who had a loss of lumbar lordosis and a loss of lumbar mobility before laminectomy tended to have poor outcomes regarding low back pain.
I think this article points out that both structure and function are important. Which makes sense. If you have a wheel and it isn’t round that’s not good and if it’s round but won’t turn that’s also bad. You need both structure and function. But everyone who ever had a bicycle knows that.
