The Relationship between Sacral Kyphosis and Pelvic Incidence.

Study Design: Retrospective cohort study.

Purpose: Evaluate the fixed anatomical parameter of sacral kyphosis (SK) and its relationship with pelvic incidence (PI).

Overview Of Literature: Pelvic parameters determine pelvic and lumbar spinal position.

Myelography in the Assessment of Degenerative Lumbar Scoliosis and Its Influence on Surgical Management.

Objective: Myelography has been shown to highlight foraminal and lateral recess stenosis more readily than computed tomography (CT) or magnetic resonance imaging (MRI). It also has the advantage of providing dynamic assessment of stenosis in the loaded spine. The advent of weight-bearing MRI may go some way towards improving assessment of the loaded spine and is less invasive, however availability remains limited.
