FIELD: medicine.
SUBSTANCE: invention relates to a traumatology and orthopedics and may be useful for surgical treatment of degenerative spondylolisthesis of lumbar spine. Placed at the head placed pedicle screws rods with a shape corresponding to an anatomically correct shape of the undeformed spine, made of a material with thermomechanical shape-memory-based intermetallic NiTi with flexural strength in the range 25-85 N/mm and a modulus of 15-20 GPa, pre cooled to a temperature below the martensitic transformation inverse phase intermetallic NiTi and curved shape degenerative spine of the patient, the metal fixing rod material with thermomechanical shape-memory degenerative spine give patient anatomically correct shape by heating the body heat of the patient.
EFFECT: method allows you to keep the mobility of the lumbar spine, to ensure recovery of the configuration of the spinal canal.
