Modified Cemented Bipolar Prosthesis Replacement For The Treatment Of Geratic Intertrochanteric Comminuted Fractures

Objective:To observe the clinical result and assess clinical value of modified cemented bipolar hemiarthroplasty for treatment of geratic unstable intertrochanteric hip fracture by comparing the modified procedure of cemented bipolar prosthesis replacement with traditional methods.Methods:Twenty-one consecutive patients with unstable intertrochanteric fractures were treated in our hospital from January 2006 to February 2010.including 7 cases Evans type IIA, 9 cases Evans type IIB and 5 cases Evans type III. Ten cases (10 hips) were treated with modified cemented bipolar hemiarthroplasty and the others were treated with traditional procedure. There were 8 male cases (8 hips) and 13 female cases, the average age of the patients was 75.2 years. The operations were carried out through lateral approach by the same group of orthopedic surgeons. The operation time, blood loss, hospital day, and postoperative Harris scores of two groups were recorded. The data was checked and analyzed with the spss17.0 (statistics package for social science) by the T-test or Non-parametric test.Results:The average operation time of the modified group was significantly shorter compared with traditional group (p<0.01). The mean postoperative 14th day's Harris scores of modified group was higher than the traditional group (p<0.05). There were no significant difference in the blood loss volume and the hospital day between two groups.Conclusions:The improved operative procedure of modified cemented bipolar hemiarthroplasty can shorten the operation time and has better results in treatment of geriatric intertrochanteric comminuted fractures.
