Abstract:

Objective

To observe the effects of proximal femoral locking compression plate (LCP)and proximal femoral nail antirotation (PFNA) in the treatment of unstable femoral intertrochanteric fracture.

Methods

A total of 120 patients with unstable femoral intertrochanteric fracture admitted tothe hospital from April 2019 to January 2022 were selected, anddivided into LCP group and PFNA group by random number table method, with 60 cases in each group. Surgical conditions, postoperative recovery, hip function at 3 monthsand 6months after operation, and the incidence of complications during postoperative follow-up period were compared between the two groups.

Results

All 120 patients received complete follow-up,with a follow-up rate of 100%, and both groups continued to be followed up until 6 months after discharge.The operation time, intraoperative blood loss and postoperative drainage volume of LCP group were longer/more than those of PFNA group (t=15.576, 18.734, 11.455, all P=0.000). At 3 months and 6 months after surgery,the excellent rate of Harris score in the LCP group was lower than that in the PFNA group(t=8.781,20.822, 12.362, all P=0.000).The excellent and good rate of Harris score in LCP group was lower than that in PFNA group (χ2=9.377, 3.927, P=0.002, 0.048), but there was no significant difference between the groups in the total incidence of complications during postoperative follow-up.

Conclusion

PFNA internal fixation has the advantages of less trauma, shorter operation time and faster postoperative recoveryin the treatment of unstable femoral intertrochanteric fracture. It is more conducive tojoint function recovery on the affected side.

Key words: Unstable femoral intertrochanteric fracture, LCP, PFNA
