Abstract Objective: To explore the effects of intramedullary fixation and inverted less invasive stabilization system (LISS) on elderly patients with unstable intertrochanteric fractures. Methods: 98 elderly patients with unstable intertrochanteric fractures in our hospital from July 2015 to July 2017 were selected for the study. 98 patients were divided into group A (odd number, 49 cases) and group B (even number, 49 cases) according to the odd and even hospitalization number. Group A was given intramedullary fixation, and group B was given inverted LISS. The operation indexes (total bleeding volume, operative time, hospital stay, first full weight-bearing time, fracture healing time), Harris score at 1 year after operation and incidence rate of complications were compared between the two groups. Results: The total bleeding volume in group A was more than that in group B, and the operative time, hospital stay first full weight-bearing time and fracture healing time were shorter than those in group B (P<0.05). There were no significant differences in the Harris score at 1 year after operation and incidence rate of complications between the two groups (P>0.05). Conclusion: Intramedullary fixation and inverted LISS both have good efficacy and high safety in the treatment of elderly patients with unstable intertrochanteric fractures, and there is no difference in hip recovery after operation. However, intramedullary fixation can shorten the operative time and hospital stay, and can more rapidly complete recovery after operation.
