[Abstract]Objective： To investigate the effect of surgical timing of proximal femoral nail anti-rotation （PFNA）internal fixationon fracture healingand prognosis inpatients with intertrochanteric fractures of femur. Method：A total of 8O patients with intertrochanteric fractures offemuradmited to the Third People's Hospital of Jingdezhen from January2O21 to December 2O24 were selectedand divided into two groups according tothe random number table method，with 4O cases in each group. Both groups underwent PFNA internal fixation treatment.The early group underwent the surgery within 72 hours after fracture， while the delayed group underwent the surgery 72 to 96 hours after fracture.The therapeutic efects，perioperative indicators，incidenceofcomplicationsand follow-up results ofthe two groups were compared.Result： The total effctive rate of treatment in the early group （95.00% was significantly higher than that in the delayed group （72.50 % ） P <0.05）. Compared with the delayed group，the early group had less intraoperative blood lossand hidden blood loss，shorter hospital stayand lowerhospitalization cost 0 P <0.05）.Compared with thedelayed group，the incidence ofcomplications intheearly group was significantly lower 0 P <0.05）. Compared with that before the surgery，the Harris hip score （HHS）of both groups increased at 6 months after the operation，and that in the early group was higher than that in the delayed group （ P <0.05）. The fracture healing time in the early group was shorter than that in the delayed group （ P <0.05）. Conclusion： PFNA internal fixation within72 hours afterfracture can efectively promote fracture healing and improve prognosis in patients with

intertrochantericfracturesof femur.
