[Does removal of the syndesmotic screw improve clinical results of operative treatment of ankle fractures with concomitant syndesmosis injury?].

INTRODUCTION

The routine procedure in cases with distal tibio-fibular syndesmotic ruptures associated with ankle fracture, is temporary fixation with a screw which is usually removed after a period considered long enough for the healing of torn syndesmotic ligaments. This ussualy requires need for a second hospitalization and generates additional costs for the health care system. The potential advantege of removing the syndesmotic stabilization is often questioned.

AIM OF THE PAPER: Aim of this study is to compare the clinical results of surgical treatment of ankle fractures with concomitant syndesmosis injury in patients where where syndesmotic screw was remowed before starting weightbearing and left intact.

MATERIAL AND

METHODS

In 33 patients treated surgically between 2006-2007 distal tibiofibular syndesmosis injury associated with ankle fractures was diagnosed and fixed with syndesmotic screw. In 13 patients, after average 14 weeks (from 7 to 22 weeks) syndesmotic screw was remowed and in 20 cases left intact. In 8 patients screw broke after full weightbearing was started. The average follow up period was 37 months. For the evaluation of treatment AOFAS hind-foot score (American Orthopedic Foot and Ankle Society) was used.

RESULTS

The mean AOFAS score for patients with remowed syndesmotic screw was 89 points while in groups where there was a spontaneous fracture of the screw or screw was left intact the results were respectively 85 and 87 points and did not differ significantly between groups.

CONCLUSION

The removal of syndesmotic stabilization before weightbearing does not significantly improve the outcome of operative treatment of ankle fractures with syndesmosis injury.
