However, the severe motor deficit and noncontained-type seem to be more associated with delayed recovery. Researchers examined 76 patients who underwent microsurgical or microendoscopic discectomy for LDH at the L4/L5 level.
Of the 76 patients examined, 56.6 percent suffered from motor deficit before surgery and 93 percent of those patients completely recovered within a mean duration of four months. The multivariate logistic regression analysis showed that noncontained-type and migrated herniated nucleus pulposus were important risk factors for motor deficit.
Severe motor deficit and noncontained-type were identified as risk factors for delayed recovery.
