Don't Forget the Legs! Spinopelvic-extremity Alignment and Assessment in the Treatment of Spinal Deformities

Main Content

Course Information


It is well known in the pediatric and adult population that there is an important balance between the spine and lower extremities. Changes in pelvic parameters can alter strategies in both populations. Lower extremity deformities or leg length differences must be considered to achieve optimal outcomes. Recent studies investigating the relationship between the spine and the pelvis have refined our understanding of pelvic and spinal orientation. Spine-pelvis-hip radiographic parameters have been used to assess balance in patients with spinal deformity and spondylolisthesis. This can affect the native and replaced him in children and adults. The goal of this course is to provide a greater understanding of optimal harmony between the pelvis, lower extremities and spine to achieve ideal outcomes in pediatric and adult spinal deformity patients.


Target Audience:

Spine surgeons (orthopaedic and neurological surgeons), residents, fellows, nurses, nurse practitioners, physician assistants


Learning Objectives:

  1. Identify the implications of sagittal imbalance and long spinal fusions on sagittal acetabular orientation during THA.
  2. Recognize the influence of lumbar osteotomy on sagittal acetabular orientation.
  3. Realize the implications spine surgery has on later THA
  4. In the AIS population, be aware of how lower extremity deformities can affect spine deformity and change surgical planning
  5. Know how variations in pelvic parameters can alter strategies in the pediatric spine
  6. Gain understanding of how Neuromuscular Scoliosis relates to Neuromuscular hip deformity.
