Abstract

OBJECTIVES
Purpose of this study is investigation the influence of intravenous and oral bisphosphonate to bone union and clinical results in patient treated with plate fixation in an osteoporotic distal radius fracture.
MATERIALS AND METHODS
The medical records of 160 patients with an osteoporotic distal radius fracture treated with plate fixation in our hospital between January 2008 and April 2012 were reviewed retrospectively. The patients were classified by 3 groups; who did not administrate bisphosphonate after surgery as Group I (n=69), administrated oral bisphosphonate after surgery as Group II (n=44), and administrated intravenous bisphosphonate as Group III (n=47). After surgery, bone union, radiologic parameters, disabilities of the DASH score and range of motion of wrist were assessed.
RESULTS
Mean time of bone union was 6.7 weeks in Group I, 6.8 weeks in Group II, and 7.1 weeks in Group III. There was no significant difference between three groups (P=0.571). Bone union rate on 6weeks shows no significant differences between three groups (P=0.16). Three groups also have no significant differences in all radiologic and clinical parameters.
CONCLUSION
This study shows that early initiation of oral and Intravenous bisphosphonate did not affect bone union and clinical results compared to group who did not administrate bisphosphonate result in patient treated with plate fixation in an osteoporotic distal radius fracture.
