Calculating anterior glenoid bone loss using the Bernageau profile view

Area of Science:

• Orthopedic Surgery
• Radiology
• Medical Imaging

Background:

• Glenoid bone loss is a significant factor in shoulder instability.
• Accurate measurement of glenoid bone loss is crucial for treatment planning.
• Traditional methods may have limitations in accessibility or cost.

Purpose of the Study:

• To evaluate the efficacy of the Bernageau view for measuring glenoid bone loss.
• To compare the accuracy of the Bernageau view with 3D CT scans.
• To establish the reproducibility of the Bernageau view in assessing glenoid erosion.

Main Methods:

• Fifty healthy subjects underwent Bernageau view X-rays.
• Ten patients with recurrent anterior shoulder dislocations were assessed using both Bernageau view X-rays and 3D CT scans.
• Three blinded evaluators measured glenoid rim distances on radiographs.

Main Results:

• The Bernageau view showed no significant statistical difference compared to 3D CT scans for normal glenoid distance, erosion distance, and percentage of bone loss.
• The average difference in bone loss percentage between the two methods was minimal (2.28%).
• The Bernageau view demonstrated high accuracy and reproducibility.

Conclusions:

• The Bernageau radiographic view is a precise and dependable method for quantifying glenoid bone loss.
• Results from the Bernageau view are comparable to those obtained with 3D CT scans.
• This technique offers a viable alternative for assessing glenoid erosion.
