| Background: Pelvic fracture is one of the most common fractures in the elderly, especially in the intertrochanteric region. Therefore, in the present study, an external fixator was designed specifically for intertrochanteric fractures. The present study aimed to compare the operating time, amount of bleeding, and mortality rate between the patients who received either dynamic hip external fixators (DHEF) or dynamic hip screw (DHS). Methods: In 2018, 46 patients with intertrochanteric fracture due to trauma and high anesthesia risk were included in the study and randomly assigned to two groups of control (n=24, patients treated with DHS) and intervention group (n=22, patients treated with the DHEF). Treatment was carried out using the DHEF which was newly designed and placed outside the patient's body under short and light anesthesia. After 3 and 12 months of follow-up, the two groups were compared for some variables, including mortality rate, pain intensity, Harris hip score (HHS), cut-off rate of the device, femoral neck angles before and after the operation, hemoglobin changes, hematocrit levels before and after the operation, the number of injected blood units, and the number of hospitalization days. Results: Mortality rate was higher in open surgery with DHS. The assessment of variables in both intervention and control groups demonstrated that duration of operation (P<0.001), hospitalization length, time to union (P=0.001), pain intensity five days after the operation, as well as changes in Hb and HCT, were significantly higher in the control group than the intervention group. The mean HHS scores of 83.5±14.3 and 78.2±11.5 were gained for the DHEF and DHS groups, respectively (P=0.22). conclusion Considering the superior results of treatment with the external fixator in comparison with the DHS, such as lower mortality rate and fewer complications, a dynamic hip external fixator can be prescribed in patients with intertrochanteric fractures and high anesthesia risk.
