Minimally invasive dynamic hip screw for treatment of femoral intertrochanteric fracture in elderly patients

Objective:To investigate the clinical effects of minimally invasive dynamic hip screw (DHS) and conventional DHS on treatment of femoral intertrochanteric fracture in elderly patients. Methods:Among the 74 cases with femoral intertrochanteric fracture, 40 cases were performed with minimally invasive DHS, the other 34 cases with conventional DHS. These data such as wound size, surgical time, lost blood, blood transfusion, Hb drop, hospitalization days, healing time and rate of fineness were compared between the two groups. Results:All cases followed up for 12-24 months were found well recovered without disunion and death. Wound size, surgical time, lost blood, blood transfusion, Hb drop, hospitalization days and hematoglobin variation in minimally invasive DHS group were less than that in conventional DHS group (P0.05 or P0.01). However, there was no significant differences between the two groups in terms of healing time and rate of fineness (P0.05). Conclusions: There were similar therapeutic effects between minimally invasive dynamic hip screws and conventional dynamic hip screw on treatment of femoral intertrochanteric fracture in elderly patients. But the minimally invasive DHS technique produces better outcome measures in the operating time, hospitalization days and blood loss compared to the conventional approach.
