Hamatolunate impingement

Case contributed by Dr Tim Luijkx


Contusion hand/wrist 2 years ago. Now pain and swelling dorsal aspect of hand.

Patient Data

Age: 55
Gender: Male

Lunate type 2 morphology with lucent areas in adjacent areas of lunate and hamate.


Location of pain marked (dorsal of base of MC2 and MC3).

There is a type 2 lunate morphology with articulation of hamate and lunate. Oedema located in the proximal aspect of the hamate and cystic lesion in the lunate. Cartilage defect between lunate and hamate, best appreciable on coronal PD. 

Case Discussion

Findings consistent with hamatolunate impingement syndrome resulting in cartilage damage and bone marrow oedema. These findings may very well explain the patient's pain located slightly distally from the hamato-lunate articulation.

On plain films the anatomy of the lunate bone should be observed. When there is an articulation with the hamate there is a lunate type 2 configuration, which predisposes for hamatolunate impingement.
