METHOD OF TREATING CHRONIC UNSTABLE INJURIES OF PELVIC RING WITH VERTICAL DISPLACEMENT IN FRACTURES OF LATERAL MASS OF SACRUM AND INJURIES OF SACROILIAC JOINTS Russian patent published in 2024 - IPC A61B17/62 A61B17/68 

FIELD: medicine.

SUBSTANCE: invention relates to traumatology and orthopedics, and can be used for treating old unstable vertically displaced pelvic ring injuries with fractures of the lateral mass of the sacrum and injuries of the sacroiliac joints. Patient is placed on an operating table on a stomach with a roller under an upper chest. Midline surgical approach is performed along a projection of the spinous processes of the lumbar and sacral vertebrae at the level of LI-SIII. Transpedicular screws are inserted from the right and left sides into the bodies of two lumbar vertebrae, as well as two transpedicular screws into the posterior spines of the displaced ilium and one screw into the intact ilium. Ilium-supported lumbar-pelvic fixators are installed: from the intact side, the curved support bar is blocked on the heads of said transpedicular screws inserted into the posterior iliac spine, in the neutral position, on the side of pelvic bone displacement, the curved support bar is placed on the heads of the above transpedicular screws with locking on the screws inserted into the posterior iliac spine. Reclining forceps are used to eliminate the displacement and to lock the screws inserted into the vertebral bodies. Curved support beams are connected by a pair of transverse ties. Wound is closed. Patient is placed on his/her back with a roller under the lumbar spine; X-ray control is performed. Rods are inserted into iliac wings and fixed to semi-rings whereon a pelvic support is mounted. After reduction of residual displacements of anterior pelvic semi-ring, the above support is stabilized.

EFFECT: method provides elimination or reduction of chronic vertical displacement of the corresponding half of the pelvis due to reliable stabilization of lumbar-pelvic fixators and application of external fixation apparatus, providing restoration of static-dynamic function of pelvis.
