Sacral Fractures - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the classifications of Sacral Fractures. Fractures of the pelvis include sacral fractures which can vary in severity from mild to severe. Types of fractures of the sacrum: modified from the Denis classification Zone I: injury lateral to the sacral foramina. Zone II: injury involving the sacral foramina. Spinal canal is not involved. Zone III: injury extends into the spinal canal. Zone I •Sacral Alar fracture •Neurological deficit less than 5%. •Involves L5 nerve root •Foot drop Zone II •Formainal zone •Neurological deficit 30%. •Involves S1, S2 nerve roots. •Most difficult zone to fix. •Associated with some loss of fixation. Zone III •Central canal •Fractures involving the sacral canal •Neurological deficit 60-100% •Cauda equine •Loss of bladder, bowel and sexual function. •Maybe either longitudinal or transverse. Zone III Longitudinal (midline fracture) •involving the sacral canal •CT axial cut clearly shows the injury. •Canal compromise usually requires surgical decompression. Zone III transverse fracture •Weakest zone is located between S2 and S3. •Axial loading causes transverse canal fracture at the weakest part. •Can lead o canal compromise •Better detected on LAT view of the sacrum. •CT axial cuts will show double foraminal fracture. •On the AP view: double shadow, Proximal part connected to the spine, the distal part connected to the pelvis.
