Acetabular angle | Radiology Reference Article - Radiopaedia.org
2024年5月16日 · The acetabular angle, also known as Sharp angle 6, is a radiographic measurement most commonly used to evaluate potential developmental dysplasia of the hip (DDH) in children and acetabular dysplasia in adults.
Developmental Dysplasia of the Hip (DDH) - Orthobullets
2023年4月6日 · Developmental Dysplasia of the Hip is a disorder of abnormal development resulting in dysplasia, subluxation, and possible dislocation of the hip secondary to capsular laxity and mechanical instability.
Acetabular index | Radiology Reference Article - Radiopaedia.org
2024年12月3日 · The acetabular index, also known as the acetabular roof angle or Tönnis angle, is a radiographic measurement of acetabular roof inclination. It is useful in assessing for developmental dysplasia of the hip (DDH) as well as pincer morphology in femoroacetabular impingement (FAI) .
Acetabular angle - diagram | Radiology Case - Radiopaedia.org
The acetabular angle is a plain film measurement used when evaluating developmental dysplasia of the hip (DDH) which is measured between Hilgenreiner's line and a line parallel to the acetabular roof. At birth it should be less than 28 degrees, and should progressively reduce with maturation of the hip.

2020年2月1日 · It is the most useful measure of acetabular dysplasia until 6 years of age. It is formed between Hilgenreiner line and the acetabular roof. In newborns, values of 30° ±4° in females and 26° ±5° in males are considered normal. Gradually this angle becomes smaller, with a mean value of 20° ±3° in females and 18° ±4° in males at 1 year ...
Morphometric study of acetabular depth and coverage and their …
To determine acetabular inclination, Tönnis angle was measured. Acetabular depth & width ratio (ADR) was evaluated by dividing acetabular width by depth, and multiplying by 100. There was significant increase in Sharp angle and Tonnis angle in …
Which Acetabular Landmarks are the Most Useful for Measuring …
The acetabular index is the angle formed between the roof of the acetabulum and the Hilgenreiner line, which connects the triradiate cartilages of both hips and is placed at the inferior bony margin of the ilia .
From dysplasia through control and overcoverage, the lateral center-edge angle, acetabular arc, and anteroposterior/craniocaudal coverage increased. In contrast, the medial center-edge angle, extrusion/acetabular index, Sharp angle, and prevalence of the posterior wall sign decreased.
Hip Disorders - Radiology Key
2016年5月24日 · FIG. 27.5 • Acetabular angles in a normal AP pelvis radiograph. Lines are drawn connecting the inferomedial and superolateral aspects of both acetabular roofs. The acetabular angle is formed between each of these lines and the horizontal Hilgenreiner line.
Assessment of three-dimensional acetabular coverage angles
2020年8月6日 · We have developed software code that allows the end user to obtain detailed measurements of the acetabulum using traditional computed tomography data. We provide the code and detailed instructions on how to use it in this article.
