Objectives/Interrogation: The volar rim fragment is an attachment site for the short radiolunate and the volar distal radioulnar ligament. Its unstable fixation can lead to articular incongruity, volar or dorsal subluxation of the carpus and distal radioulnar instability. The involvement of this fragment on distal radius fractures is relative common and many studies of Literature have been focused on its treatment.

This study evaluate the clinical and radiological outcome of a new device born to treat marginal articular fractures of the distal radius, focusing on dorsal fracture-dislocations. The device (Aptus Wrist Distal Radius System 2.5, Medartis AG, Basel, Switzerland) represent a fragment-specific fixation system.

Methods: A retrospective review was conducted on the first 45 patients with a mean follow-up of 23 months including postoperative clinical evaluation, grip strength, CT scan and X-ray control.

Results and Conclusions: All fragments, except one, healed and maintained reduced until the final follow-up. The carpus was aligned with the distal radius in all patients presenting with a radiocarpal dislocation.

The Hook Plate stabilizes distal fragments at their bone-ligament interface. In addition to bony reduction, the device permits to stabilize the capsule and ligaments, as volar bony ligament avulsions, in a picture of dorsal radiocarpal dislocation.
