Abstract: Objective To explore the causes and prevention measures of early postoperative compli-cations of unstable intertrochanteric fracture patients. Methods Atotal of 120 patients with unstable intertrochanteric fracture were assigned to two groups, the proximal femoral nail antirotation group （group A, n=60）and the locking plate internal fixation operation group（group B, n=60）. The postoper-ative recovery and complications were compared between the two groups. Results Group A was signifi-cantly better than group B in the operation, fracture healing and daily living ability, and the differences between the two groups were statistically significant（all P values <0.05）. The complications of group A were associated with delayed union, coxa vara and femoral head cuttingout of dynamic hip screw. Group B was mainly focused on the delayed healing of fracture. In the two groups, there were a small number of patients with the complications of pressure sores, urinary tract infection, pulmonary infection, and deep venous thrombosis in the lower extremity. There was no significant difference in the total incidence of the two groups（P<0.05）. Conclusion Complications can occur early in patients with unstable intertrochan-teric fracture after proximal femoral nail antirotation and locking plate internal fixation operation, and the corresponding preventive measures should be taken into account.
