Summary
Significant hip bone mineral density (BMD) asymmetry exists in older adults, linked to gluteal muscle and femoral anteversion differences. Bilateral hip assessment using quantitative computed tomography (QCT) can improve osteoporosis detection.
Area of Science:
- Orthopedics
- Radiology
- Gerontology
Background:
- Side-to-side differences in hip bone mineral density (BMD) are observed but not well understood.
- Morphological factors contributing to hip BMD asymmetry require clarification.
Purpose of the Study:
- Quantify hip BMD differences between right and left hips.
- Identify morphological factors associated with BMD asymmetry using quantitative computed tomography (QCT).
Main Methods:
- Analyzed QCT data from 82 adults (median age 75).
- Calculated bilateral hip BMD and side-to-side percentage differences.
- Assessed gluteal muscle volume and femoral anteversion for association with BMD differences.
Main Results:
- Median BMD difference was 3.0%; 26% exceeded 5%.
- Greater gluteal muscle volume and femoral anteversion asymmetry correlated with larger BMD differences.
- Lower BMD was observed on the side with smaller gluteal muscle volume and greater femoral anteversion.
Conclusions:
- Clinically significant hip BMD asymmetry is common in older adults.
- Unilateral measurements may underestimate osteoporosis risk.
- Bilateral hip assessment, especially with QCT, is recommended for accurate osteoporosis screening.

Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
