Effect of PFNA on the prognosis of elderly patients with intertrochanteric fracture at different time after injury

ObjectiveTo investigate the effects of the proximal femoral nail antirotation(PFNA) on prognosis of elderly patients with intertrochanteric fracture at different time after injury.

MethodsThe clinical data of 142 intertrochanteric fracture patients treated with PFNA were retrospectively analyzed.According to the time from fracture to operation, the patients were divided into the early group(operation within 48 hours after fracture) and elective group(operation after 48 hours of fracture), and followed up for 1 year.The fracture healing time, complications, clinical efficacy and prognosis were compared between the two groups.

ResultsThe hospital stay in early group was shorter than that in elective group(P < 0.05), the incidence rate of complications in early group during hospitalization was significantly lower than that in elective group(P < 0.01), and the long-term mortality rate in early group was lower than that in elective group(P < 0.05).There was no significant difference in clinical healing time, short-term mortality and hip joint function at last following up between the two groups(P>0.05).

ConclusionsCompared with the elective PFNA surgery, the early surgery can reduce the risk of complications during hospitalization, shorten the length of hospital stay, and reduce the long-term mortality, which has a positive impact on the standardized treatment of elderly hip fracture.Early surgery should be the first choice for patients with good general condition.
