DYNAMIC COMPARED WITH STATIC EXTERNAL FIXATION OF UNSTABLE FRACTURES OF THE DISTAL PART OF THE RADIUS. A PROSPECTIVE, RANDOMIZED, MULTICENTRE STUDY
J Bone Joint Surg (Am) 2010; 92-A: 1687-96
Background: External fixation is an established method of treating certain types
of distal radial fractures. We have designed a dynamic
external fixator to treat these fractures. The purpose of the present study was to
compare this devicewith current static bridging external
fixators in terms of anatomical and functional results.
Methods: We conducted a prospective randomized study
to compare the radiographic and clinical results of dynamicexternal fixation with those of static external fixation for the
treatment of seventy unstable distal radial fractures. Mobilization of the
wrist was begun in the dynamic fixator group on the day after surgery. The
external fixation frames were kept in place for a mean of six weeks. The
patients were assessed clinically and radiographically at the time of removal
of thefixator and at three, six, and twelve
months.
Results: Dynamic fixation resulted in a significantly
better restoration of radial length at all follow-up visits in comparisonwith static fixation. There were no significant differences in
radial tilt or radial inclination between the two groups. Wrist flexion,
radial deviation, and pronation-supination were regained significantly faster
in the dynamic fixator group. Wrist extension was significantly better in the
dynamic fixator group in comparison with the static fixator group at all
follow-up times. Self-evaluation with use of the Disabilities of the Arm,
Shoulder and Hand score and a visual analog pain score demonstrated no significant
differences between the two groups at the time of the latest follow-up.
Superficial pin-track infections were significantly more common in the
dynamic external fixator group than in the static fixator group.
Conclusions: Continuous dynamic traction with a dynamic external fixator compares
favorably with the use of static external fixators for the treatment of
unstable fractures of the distal part of the radius.
