Spinal Deformity for Residents-Spondylolisthesis Reduction Technique

Video Transcription

Video Summary

The video summarizes the importance of understanding biomechanics in spinal surgery. The speaker discusses the common errors in diagnosis and biomechanics made by surgeons, and emphasizes the need to have a fundamental understanding of biomechanics in order to avoid failures in surgeries. The speaker explains various concepts related to biomechanics, such as forces, translational and shear forces, stress and strain, moment arm, energy transfer, and the role of neurostructures. Different surgical options for addressing listhesis are also discussed, including in situ fusion, instrumented posterior fusions, circumferential fusions, and dome osteotomies. The speaker highlights the need to individualize the surgical approach based on the patient's condition and the biomechanics involved. Techniques such as the Bowman technique, fibular strut graft, and VCRs are presented as examples. The speaker concludes by emphasizing the importance of understanding the biomechanics involved in order to choose the appropriate surgical construct and ensure successful outcomes. The video does not provide any credits for the content.
