Friedman line

Last revised by Craig Hacking on 22 Dec 2022

The Friedman or scapular line can be used to determine glenoid version and glenoid bone loss 4. Glenoid version angle measured by the Friedman method has better inter-reader reliability than the scapular body method 2

Measurement

The Friedman line is drawn along the long axis of the scapula from the tip of the medial border to the centre of the glenoid fossa 1-4
