Pelvic Bone Deformity and Its Correlation with Acetabular Center-edge Angle.

Area of Science:

• Orthopedics
• Radiology
• Anatomy

Background:

• Pelvic bone deformities can impact hip joint function and diagnosis.
• The acetabular center-edge (CE) angle is a key measurement in assessing hip joint stability.
• Asymmetry in pelvic structures may be linked to hip joint abnormalities.

Purpose of the Study:

• To evaluate pelvic bone deformities.
• To assess the correlation between pelvic bone deformities and the acetabular center-edge (CE) angle.
• To investigate asymmetry in superior and inferior pelvic axes.

Main Methods:

• Prospective evaluation of 93 patients aged 20-60 years.
• Exclusion of patients with metabolic diseases, prior hip/spine surgery, or advanced hip arthrosis.
• Analysis of anteroposterior pelvic radiographs for CE angle, acetabular index, and pelvic axis measurements (H1, H2, V1, HR, VR).

Main Results:

• Significant correlation found between acetabular CE angle variations and superior hemipelvis asymmetry.
• Group 1 (patients with deformities) showed significantly higher rates of asymmetry in H1, H2, and V1 compared to the control group (p < 0.001).
• Asymmetry in H2 was particularly prevalent in Group 1 (90.9%).

Conclusions:

• A correlation exists between acetabular center-edge (CE) angle variations and superior hemipelvis asymmetry.
• Improved understanding of pelvic morphologic alterations facilitates diagnosis of hip articular deformities.
• This study highlights the importance of evaluating pelvic symmetry in conjunction with hip joint assessments.
