Surgical treatment within six months of lumbar disc herniation

October 25th, 2011 in Diseases, Conditions, Syndromes /

A new study in the Journal of Bone and Joint Surgery (JBJS) found that patients with herniated lumbar disc symptoms were significantly worse if the patients had symptoms for more than six months prior to treatment, compared to those who had symptoms for six months or less. Symptoms included pain, function, general health, work status and patient satisfaction.

"Patients often ask their physicians whether the duration of their symptoms will affect their potential for a full recovery, and the goal of our study was to address this question," said Jeffrey A. Rihn, MD, and one of the study authors.

Several studies conducted over the past 30 years have demonstrated the effectiveness of lumbar discectomy. One of the most common spinal surgical procedures, lumbar discectomy involves the removal of the material that is pressing on a or the to treat lumbar disc herniation. However, despite the proven effectiveness of this procedure, there is no consensus on the timing of surgery. Various studies suggest waiting anywhere from "an appropriate amount of time" to 12 months after symptoms begin.

"According to our study and generally speaking, patients who had symptoms for more than six months had less improvement in pain, function, general health, work status, and ," said Dr. Rihn.

Study Details

At all follow-up intervals, outcomes were significantly worse in patients who had symptoms for more than six months prior to treatment than in those who had symptoms for six months or less.

The study authors also found that operative treatment was significantly more effective than nonoperative treatment. However, the relative increased benefit of surgery over nonoperative treatment was not dependent on the duration of symptoms.

"Patients who have had symptoms for longer than six months can find relief with either nonoperative treatment or surgery, but they may not reap as much benefit as those who have had symptoms for six months or less," said Dr. Rihn. "Surgery still has significant benefit compared with nonsurgical treatment, even in patients who have had symptoms for longer than six months."
