Identifying osteoporotic vertebral endplate and cortex fractures

Area of Science:

• Radiology
• Orthopedics
• Metabolic Bone Disease

Background:

• Osteoporosis is a common metabolic bone disease characterized by vertebral fractures (VFs), the most frequent type of osteoporotic fracture.
• Prevalent VFs independently elevate the risk of subsequent vertebral and non-vertebral osteoporotic fractures, irrespective of bone mineral density (BMD).
• Accurate VF reporting is critical for timely osteoporosis management, with radiologists playing a key diagnostic role.

Purpose of the Study:

• To provide teaching material for physicians and researchers on identifying vertebral endplate/cortex fractures (ECF).
• To emphasize the detection of ECF, particularly those not associated with apparent vertebral body collapse.
• To highlight the importance of differentiating true fractures from variations in vertebral shape.

Main Methods:

• Review of existing morphometrical and radiological methods for detecting osteoporotic VFs.
• Introduction of the algorithm-based qualitative approach (ABQ) focusing on vertebral endplate changes.
• Discussion of potential challenges, including fractures without measurable height/area changes or gross deformity, and the exclusion of mimicking conditions.

Main Results:

• The ABQ criteria prioritize evidence of endplate fracture over variations in vertebral shape.
• Vertebral cortex fractures can occur without initial endplate involvement or gross vertebral deformity.
• Standardized radiologic evaluation combined with morphometry measurement is proposed as the optimal approach for VF detection and classification.

Conclusions:

• Accurate identification of vertebral endplate/cortex fractures (ECF) is essential for diagnosing and managing osteoporosis.
• The algorithm-based qualitative approach (ABQ) offers a structured method for detecting subtle VFs.
• A combined expert radiologic evaluation and morphometry measurement strategy is recommended for comprehensive VF assessment.
