Distal radius fractures involving the volar rim could be challenging to manage. The short radiolunate ligament which originates proximally from the volar rim plays an important role in radio-carpal joint stability. Literatures have shown that volar carpal subluxation could develop if the volar rim fragment was not appropriately stabilized. In this video, we present a special case with an extremely small volar rim fragment in an intra-articular comminuted distal radius fracture. Intraoperatively, we found that this fragment was flipped over up-side down. We then reduced the fragment 180 degrees in order to put it back to its normal position. Radio-carpal instability was shown under fluoroscopy when the volar rim fragment was not secured. Surgical technique for this ultra-distal volar rim fracture fixation is present in detail. Follow-up X-ray and CT showed the evidence of adequate union progress and well aligned radio-carpal axis. This case emphasizes the importance of understanding the biomechanics of volar wrist ligaments and intraoperative visualization of volar rim fragment.
