Spinal Deformity for Residents-Sagittal Balance Principles

Video Transcription

Video Summary

In this video, the speaker discusses the concept of sagittal balance in relation to lumbar lordosis. They explain that the normal lumbar curve can vary from 20 to 60 degrees, and they discuss why different patients may require different degrees of lordosis. The speaker emphasizes the importance of measuring the lumbar lordosis and pelvic incidence in order to achieve sagittal balance. They explain that a ratio of 2 to 1 between thoracic and lumbar lordosis is ideal for maintaining proper posture. The speaker also introduces the concept of the sagittal vertical axis (SVA) and explains how it can be measured to assess the balance of the spine. They discuss how discrepancies between lumbar lordosis and pelvic incidence can lead to musculoskeletal issues and pain. The video concludes with a case study example that highlights the importance of considering sagittal balance in surgical planning for patients.
