ABSTRACT

Objective To explore the mid-term efficacy of biological type,long-stem artificial caput femo-ris replacement operation in the treatment of unstable senile intertrochanteric fracture.Methods 73 patients accepted the treatment of biological type long-stem artificial caput femoris replacement operation,and 64 cases were followed. After 3 months of operation,these 64 patients were divided into four groups which marked as A,B,C and D according to the Berg balance scale(BBS).Accordingly,54 patients that in grade A,B and C would be brought into in long-term follow-up study.54 cases include 25 male patients and 29 female patients with an average age of 81.6 years old who aged from 73 to 94 years old.According to Evans-Jensen classification,28 cases were Evans-JensenⅡand the left 26 cases were Evans -JensenⅢ.Results The follow-up period was in the range of 24 to78 months (mean 42months).During this period,except the 9 death cases,there was no case of femoral trochanteric ununited fracture, femoral prostheses loosening or dislocation of hip joint.In total,3 cases occurred with loss of fixing wire,4 cases occurred with acetabular wear,one case was experienced prosthesis adjacent fracture and three cases of heterotopic ossification.According to the Engh standard,all femoral prostheses got osseous fixation.The rate of excellent and good result were 88.9%with in which excellent in 23 cases and good in 17 cases.Conclusion The application of biological type long-stem artificial caput femoris replacement in the treatment of unstable senile intertrochanteric fracture can achieve satisfactory mid-term efficiency.
