Selective release of the [[anterior longitudinal ligament]] (ALL) and placement of lordotic interbody grafts using the minimally invasive [[lateral retroperitoneal transpsoas approach]] (XLIF) has been performed as an attempt to increase lumbar lordosis while avoiding the morbidity of osteotomy. smith_petersen_osteotomy.txt Last modified: 2024/06/07 02:55by 127.0.0.1
