Influence of spine biomechanics and sagittal balance on the outcome of lumbar discectomy.

Purpose: Spine biomechanics, particularly sagittal balance and spino-pelvic angulation are determinant factors in the understanding of lumbar degenerative disease. These concepts translated into objective measurements are progressively being integrated into clinical practice. The present study explores them as prognostic factors in patients undergoing lumbar microdiscectomy, which could help identify those at higher risk of surgical failure.
