Objectives/Interrogation: Distal radius fracture is the most common fracture in emergency room, for which open reduction and internal fixation is often performed. However, wrist arthroscopy might be needed in those patients with intra-articular fractures both in the acute phage and in the post-fixation phage. This study introduces our technique and preliminary results of arthroscopic assisted treatment of distal radius fractures combined with TFCC injuries.
Methods: 23 patients with acute DRF and 19 patients with second stage after DRF fixation were included and undergone the wrist arthroscopy. Wrist arthroscopy was used to facilitate the reduction of the articular surface. TFCC were explored and recorded if there were injuries.
Results and Conclusions: With Wrist arthroscopy, big gaps were often found between the fragments after routine open reduction and internal fixation. DRF was often accompanied by type I injury, especially the Type ID and IB injuries. In addition, DRF often accompanied by ulnar styloid injury, which led to TFCC tension disappearing. Adhesion bundle after DRF fixation was often found at the radial-carpal joint in the post-fixation phage. Regular follow-up after DRF found that Positive ulnar variance may increase. We found that better reduction of the articular surface could be achieved with wrist arthroscopy. TFCC tension will recover after ulnar styloid fixation. IF type II injury occurs, positive ulnar variance should be corrected as early as possible.
