RESUMO
<p><b>OBJECTIVE</b>To compare and analyze the clinical effects of external fixator and small splint fixator in the treatment of comminuted distal radius fracture in senile.</p><p><b>METHODS</b>From 2005.6 to 2008.6, 74 senile patients (82 sides) with comminuted distal radius fractures were divided into external fixation group (34 cases 38 sides, 27 males and 7 females, with an average of 70.05 +/- 3.70 years) and small splint fixation group (40 cases 44 sides, 29 males and 11 females, with an average of 70.30 +/- 3.48 years). The loss of volar tilting angle and ulnar inclination angle after reduction and the function scores of carpal joint after removing the fixators were compared.</p><p><b>RESULTS</b>One week after surgery, there was loss of volar tilting angle and ulnar inclination in small splint fixation (P < 0.01), and one month after removing the external fixator, the loss of angle was more obvious (P < 0.01); while the loss of angle in external fixation group was not significant (P > 0.05). After one month of removing the fixation, the functional score of wrist joint in external fixation group was obviously higher than that of the small splint fixation group (P < 0.05).</p><p><b>CONCLUSION</b>The external fixator can be adopted to treat comminuted distal radius fractures in senile, which is able to decrease the reduction loss and helpful to functional recovery.</p>
