Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Area of Science:

  • Orthopedics
  • Radiology
  • Developmental Biology

Background:

  • Developmental dysplastic hips (DDH) were historically considered anteverted.
  • Complications and imaging challenges created controversy regarding acetabular version in DDH.
  • Acetabular version measurement is complex due to the acetabulum's spiral shape and imaging variables.

Purpose of the Study:

  • To clarify the role of acetabular version, particularly retroversion, in hip disorders.
  • To establish reliable methods for assessing acetabular version.
  • To understand the clinical implications of acetabular retroversion.

Main Methods:

  • Analysis of clinical observations and imaging studies.
  • Comparison of computed tomography (CT) and orthograde pelvic radiography.

The Transition to an Anterior-Based Muscle Sparing Approach Improves Early Postoperative Function but is Associated with a Learning Curve

Published on: September 7, 2022

  • Evaluation of acetabular rim relationships on radiographs.

    • Main Results:

    • Acetabular retroversion is a feature in various hip disorders, including DDH, post-traumatic dysplasia, and congenital conditions.
    • CT imaging is inconclusive for determining acetabular version.
    • Orthograde pelvic radiography provides a reliable method for estimating acetabular version.
    • Acetabular retroversion can occur in non-dysplastic hips and result from surgical interventions.

    Conclusions:

    • Acetabular retroversion is a significant factor in hip dysplasia, necessitating individualized treatment approaches.
    • The presence of acetabular retroversion impacts surgical planning, such as corrective osteotomies.
    • Acetabular retroversion has detrimental long-term effects on hip health.
