Objective: Joints displacement has been introduced in treating intertrochanteric fracture. However, the studies on the treatment of femoral prothesis stem in elderly patients are very rare. This study aimed to observe the curative effect of auxiliary biological cemented femoral stem in treating elderly patients with unstable intertrochanteric fracture.

Methods: From January 2012 to January 2016, 85 elderly patients with intertrochanteric fracture in our department were randomly divided into two groups (control group, n=42 and observation group, n=43), who were treated with auxiliary biology cemented femoral stem replacement and biological artificial hip replacement with lengthened handle, respectively. The related clinical data were collected and compared.

Result: The average age was 79.6 years old. The prosthesis was fixed according to the Engh standard in all patients. No difference was found on the operation time between two groups (P>0.05). Observation group had significantly less bleeding volume during and after operation (P<0.05). The ambulation time in observation group was significantly shorter than that in the control group (P<0.05). Harris scores and VAS was comparable before surgery (P>0.05), which in observation group were all significantly higher than those in control group at 1, 3, and 6 months after surgery (P<0.05).

Conclusion: Treating intertrochanteric fracture elderly patients with auxiliary biological cemented femoral stem prosthesis is good for initial fixation, early walking with load, and long-term bone ingrowth, which can also greatly improve the hip joint function and patients’ life quality.
