PURPOSE: Several authors have reported excellent results of delayed reconstruction of non-union & malunion in displaced mid-shaft fractures of the clavicle and these results were equal to that of immediate fixation. But direct comparison between these treatments is rare. We evaluated the results between the immediate fixation group and delayed reconstruction group for treating displaced mid-shaft fractures of the clavicle.
We studied the results of 18 cases with immediate fixation of displaced mid-shaft fractures of the clavicle and 15 cases with delayed reconstruction of non-union & malunion after conservative management, and these cases were seen from March 2000 to February, 2006. The final postoperative outcome was analyzed according to the clinical outcomes with using the Constant score and the radiological findings of bony union.
The constant score was low in the delayed reconstruction group compare to that of the immediate fixation group (p value=0.045). For the pain score & the activities of daily living score, a statistically significant difference was seen between the two groups (p<0.05), but not for the range of motion score & the power score (p>0.05). Radiological findings of bony union were seen for both groups at an average of 8.8 weeks for the immediate fixation group and at an average of 9.8 weeks for the delayed reconstruction group.
Though the delayed reconstruction group was shown good clinical and radiological results, the immediate fixation group had a significantly better pain score, a better activities of daily living score and a better Constant score. It is important to choose the initial treatment option for displaced mid-shaft fractures of the clavicle after sufficient explanation to patients about the merits and demerits between these two treatment options
