title: [Osteosynthesis of the low lumbar spine and spondylolisthesis. Modification of the Scholner plate and pedicular screwing].
abstract: A modification of Roy Camille's Technic for better screw location into the pedicle of vertebra of the low lumbar column and lumbo-sacral junction is reported. A small 5 millimeters resection of the inferior articular process allows a more cranial drill-hole which is more steadily in the pedicle of the vertebra as confirmed by X rays controls and anatomic specimens. A 10 degree slope to a caudal direction is needed at the L5 level and a 30 degree slope to a caudal direction is required at S1 level. 50 millimeters length screw can be used for adult patients. Some modification of Scholner's plate are proposed in spondylolisthesis surgery.
