Treatment Of Unstable Intertrochanteric Fractures In The Eldly With The Prosthetic Artificial Fernord Head

Objective:To compare the clinical effect on the treatment of unstable intertrochanteric fractures in the eldly between the prosthetic replacement and the D(?)S fixation, and to approach its indication and methods.Method: 46 cases were unstable type according to Ewans typing system,and they were followed up from 3 months to 5 years. 18 cases of all had been treated wi th bipolar prosthetic replacement, and were more than 70 years old. 28 cases of all had been treated with DHS fixation, and were 72.4 years old in average.Record the operation time, amount of bleeding of two groups,and followed up how long the patients get off bed, and the occurrence of complicating diseases; all of the cases were evaluated by Harris grading system, and compared those index between two groupes. The data statistics with SPSS 13.0.Result:There was no statistics difference in operation time, amount of bleed and complications incidence rate. The replacement got off bed earlier than fixation group. But the complicates incidence of fixation group are more than replacement group because time of bed was longer.The excellent rate of replacement group is better than fixation group, but there no difference in statistic.Conclusion:The prosthetic replacement can be one kind of treatment to the unstable intertrochanteric fractures in the eldly, but we should master the operation indication strictly, and the propotional treatment according to its characteristic should be take to reduce the occurrence of complications.Because the cases of particular disease were few, it was limited to some extent to reflect the result accurately and overall. According to the result of the investigation and the abstract superiority of the prosthetic replacement, It is possible to perform the freely control study in large scale between in the prosthet ic replacement group and the internal fixation group.
