[Results after Arthroscopically Assisted Management of Intra-Articular Distal Radius Fractures].

UNLABELLED: Background/Goal: An arthroscopically assisted management of intra-articular distal radius fractures may improve the quality of reduction. Furthermore, concomitant ligament and triangular fibrocartilage complex injuries can be identified and treated. However, this approach increases the duration of surgery. If severe soft tissue lesions, such as SL-ligament disruptions are treated simultaneously, a longer post-operative immobilisation will be required. The aim of this study was to measure the clinical outcome one year after arthroscopically assisted treatment of intra-articular distal radius fractures.

PATIENTS AND

METHODS

In a retrospective study from 2011 to 2013 we identified 27 patients with intra-articular distal radius fractures who were treated with volar fixed angle plates in an arthroscopically assisted fashion. The amount of associated injuries, the duration of surgery and the time of immobilisation were documented. One year postoperatively we evaluated 23 of these patients using several scores. Patient satisfaction, range of motion, visual analogue scale and grip strength were assessed using a standardised questionnaire.

RESULTS

The mean surgery time was 111 min (60-190 min). On average, we found 1.4 (0-3) associated injuries per patient. Seventy percent (19) of all patients had a triangular fibrocartilage complex lesion, 67% (16) had some degree of scapholunate ligament lesion. The mean number of interventions in addition to the plate fixation was 1.1 per patient (0-3). Among these were debridements of the triangular fibrocartilage complex in 11 cases (41%) and scapholunate ligament repairs in 4 cases (15%). The mean immobilisation time was 22 (0-42) days. At one year after surgery, the mean Mayo wrist score was 79 (65-95) and the DASH score was 12 (0-49).

CONCLUSION

The arthroscopically assisted management of intra-articular distal radius fractures helps to identify and treat associated injuries. However, it results in extended surgery and immobilisation time, especially if concomitant intra-articular lesions are treated. In our group of patients, the clinical outcome after one year was nonetheless very good.
