Fundamentals in Spinal Surgery for Residents-Sacropelvic Fixation

Video Transcription

Video Summary

In this video, the speaker discusses the indications for extending fixation to the pelvis in spinal surgeries. They mention that high grade listhesis, long segment fusions, trauma, osteomyelitis, cancer, and treatment of L5-S1 pseudoarthrosis are situations in which fixation to the pelvis may be necessary. The main goal of extending fixation to the pelvis is to protect the S1 screw and prevent sacral insufficiency fractures. The speaker emphasizes the importance of assessing biomechanical parameters such as sacral slope, pelvic incidence, and lumbar lordosis. They also discuss the different fixation zones in the sacral pelvic unit and the advantages of iliac fixation. The speaker demonstrates the entry point and technique for placing iliac screws and highlights the potential complications one should avoid. The video concludes by mentioning that iliac screws are temporary stabilizers until the L5-S1 interbody fusion is solid. The speaker recommends referring to the full video and additional resources for more information.
