Analysis Of Two Internal Fixations Effect On The Fracture Of The Collar Bone

Objective:To compare and analyze the effect of surgical treatment for clavicle fracture by reconstruction plate and Kirschner's wire.Patients and Methods:Retrospective analyzed surgically treated 40 cases clavicle fractures that can be followed up during 1997.9-2006.7 in XiangYa hospital,28 cases in which were treated by reconstruction plate, 12 cases by Kirschner's wires,compared the effect of these two methods. The effect is assessed according to the standard of Han Ping-liang.The mean operating time, mean bleeding volume, mean heal time adopted t-test.The rate of excellent and good, the disesse incidence of postoperative complications by statistical Chi-square test,P<0.05 is to be considered having statistical significance.Results:All the cases were followed up for 6 to 96 months, in reconstruction plate group,mean operating time were 60min(45min～85min),mean bleeding volume were about 80ml (50ml～100ml).Mean heal time were 3 months(2months～5.5months).All 28 fractures healed,1 case suffered delayed union. 1 case suffered a plate breakage 2 months after the operation,this was treated by replating using reconstruction plate and supplemental autogenous iliac crest bonegrafting.The recovery was eventually satisfactory.In this group,23 cases were excellent,3 cases were good,2 cases were acceptable.The rate of excellent and good was 92.8%.InKirschner's wires group,the mean operating time were 45min(35min～60min)mean bleeding volume were50ml(35ml～80ml),mean heal time were 2.5 months(1.5months～4.5months),all the fractures got primary union except 2 cases mal-union for the Kirschner's wire loosened, 2 cases suffered delayed union, 1 case had residual shoulder pain restricting the range of motion.5 cases were excellent,2 cases were good,5cases were bad.The rate of excellent and good was 58.3%.After statistical t-test (P>0.05), there was no differences were found by operating time, bleeding volume and union time,but significant difference in rate of excellent and good. The disesse incidence of postoperative complications is lower in reconstruction plate than In Kirschner's wires group by X -test(P<0.05).Conclusion:According to the results,we conclused that reconstruction plate displayed advantages of rigid fixation, and occurs less complication than the Kirschner's wire,and possibility of early functional exercise.The function of the shoulder joint is better.
