Gender-specific factors influencing the glenoid version and reference values for it

Area of Science:

• Orthopedics
• Radiology
• Anatomy

Background:

• Glenoid version is critical for shoulder stability and pathology assessment.
• Established reference values and influencing factors for glenoid version are currently lacking.
• Valid reference values are essential for diagnosing shoulder conditions and planning orthopedic surgeries such as corrective osteotomy and shoulder arthroplasty (TSA/RSA).

Purpose of the Study:

• To identify factors influencing glenoid version.
• To establish reference values for glenoid version in a large population cohort.

Main Methods:

• A population-based study involving 3004 participants from the Study of Health in Pomerania (SHIP).
• Glenoid version was measured bilaterally using magnetic resonance imaging (MRI).
• Statistical analyses were performed to assess associations between glenoid version and factors including sex, age, body height, body weight, and BMI.

Main Results:

• The study established reference values for glenoid version in the central European population, ranging from -9° to 7.5°.
• Multiple factors, including sex and age, were found to be associated with glenoid version.
• The analysis included 3004 participants, with glenoid version measured via MRI.

Conclusions:

• Sex- and age-adjusted reference values for glenoid version are proposed.
• These adjusted values are crucial for reliable interpretation in the context of orthopedic surgery.
• The findings contribute to a better understanding of glenoid anatomy and its clinical implications.
