Medial facetectomy in recurrent lumbar nerve root compression.

This study investigated the outcome of medial facetectomy in reoperations after a previous discectomy. In a consecutive series of 98 patients with varying combinations of disc herniation, lateral stenosis, and scar, a good or moderate outcome was reached in 57% of the patients. Scar as an operative finding was a significant factor for poor outcome, especially in patients with preoperative symptoms for >1 year.

Lumbar paraspinal muscle function, perception of lumbar position, and postural control in disc herniation-related back pain.

Study Design: A follow-up study evaluating postural control, lumbar movement perception, and paraspinal muscle reflexes in disc herniation-related chronic low back pain (LBP) before and after discectomy.

Objectives: To assess the effect of discectomy on postural control, lumbar perception, and reflex activation of paraspinal muscles during sudden upper limb loading.

Summary Of Background Data: Impaired muscle function, postural control, and lumbar proprioception have been observed in LBP.
