Gliederung

Text

Objectives/Interrogation: A 40-year-old patient came to our clinic with swelling on the back of his hand and pain 14 days after a fall. Radiographs showed a larger fragment palmar of the base of the Metacarpal II in the lateral radiograph and a gap in the area of the styloid process MC-II.

Methods: The patient was operated on and the entire slightly wedge-shaped styloid process could be recovered from the palmar dislocation position and fixed with a screw osteosynthesis after cleansing to the anatomical position.

The fracture healed and after three month there was no pain and full ROM.

Results and Conclusions: The unique injury mechanism resulted from the wedge-shaped shape of the MC-II processus, and an injury mechanism that results in a dorsal displacement of the MC-II basis. The styloid process can't follow the dorsal displacement of the second metacarpal and after spontaneous reposition the styloid fragment is pushed palmar.

This is the same mechanism as in a perilunate dislocation.

To other similar cases in our unit are compared with this case.
