Locking Compression Plate( LCP) Fixation for Unstable Distal Radial Fractures in Elderly Patients

Objective To evaluate the effects of in the locking compression plate( LCP) fixation in treatment of the unstable distal radial fractures in elderly patients. Methods From January 2007 to June 20011,43 patients with unstable distal radial fractures were fixed with anatomical Locking Compression Plates and tamped bone graft. By AO classification,there were 5cases of type B2,8 cases of type B3,9 cases of type C1,15 cases of type C2 and 6 cases of type C3. The outcomes were assessed by radiographs and evaluation of wrist function through the postoperative follow- up. Results Mean follow- up time was 14. 2 months( 6 to 22 months). All cases acquired bony union with a mean healing time of 8. 2 weeks without malunion.The mean palmar tilt angle was 8. 6°( 3°to 12°). The mean ulnar inclination angle was 18. 4°( 13° to 24°). There were radial shortening in 6 cases,the mean length was less than 2 mm. According to Dienst Category,there were excellent in 17 cases,good in 23 cases,fair in 3 cases,and the total efficacy rate was 93. 02 %. There was no iatrogenic nerve injury and infection. Conclusion For the unstable distal radial fractures in the elderly patients,Locking Compression Plate fixation has satisfactory curative effect. This procedure can restore and sustain the distal radial length and smooth articular surface after the fracture reduction.
