A man consulted with us recently about the sensation of clucking he has developed after a shoulder arthroplasty done elsewhere.
On examination a shift can be felt when he flexes his shoulder.
The two anteroposterior views are not that impressive.
However, the axillary view shows a large radiolucent zone between the cemented glenoid component and the glenoid bone. Thus suggests that the component is toggling on shoulder movement.
