Right wrist pain
Patient Data
This coronal MRI T2* sequence shows the lunate projecting in the space of Poirier, bounded by the radioscaphocapitate ligament, ulnocapitate ligament, and radiolunotriquetral ligament.
This coronal MRI T2* sequence shows the lunate (arrow) projecting in the space of Poirier, bounded by the radioscaphocapitate ligament, ulnocapitate ligament, and radiolunotriquetral ligament.
Case Discussion
The space of Poirier is a normal anatomic area of poor ligamentous support at the palmar aspect of the wrist. It is located between the capitate and lunate, particularly the volar radioscaphocapitate and radiolunotriquetral ligaments. It is a weak spot through which the lunate can escape in the setting of lunate dislocation.
