Evaluating the arthritic shoulder without a CT scan using the 'truth' view.

A man in his mid 40s presented to us today with shoulder pain and limited motion.
his AP suggested mild to moderate arthritis.

However, the 'truth' view (a standardized axillary taken with the arm in the functional position of elevation in the plane of the scapula - see this link), revealed a retroverted, biconcave glenoid with posterior humeral decentering = the bad arthritic triad (BAT - see this link).

These two films provide the necessary information with which to discuss the possible surgical options and to plan the procedure.
