Is it advantageous to use the intraoperative compression option of proximal femoral nail antirotation in the treatment of osteoporotic intertrochanteric fractures? A retrospective comparative study.

The lateral extension 14 of the PFNA blade compared with that in the image taken immediately after surgery showed a borderline significant trend (Group A, 3.3 ± 1.3 mm (min, 0.5; max, 5.1) and Group B, 5.1 ± 2.1 mm (min, 1.5; max, 8.4); p = 0.092) at 3 months and statistically significant difference at 24 months after surgery (Group A, 3.6 ± 3.1 mm (min, 0.5; max, 7.8); Group B 7.8 ± 3.7 mm (min, 3.0; max, 12.5); p = 0.017).

However, at 6 weeks, the VAS scores were 35.5 (min, 15; max, 47) in Group A and 37.6 (min, 11; max, 47) in Group B ( p = 0.073), showing a slight tendency toward significance.

In this study, the IOFC group showed a shortening of the fracture union time that almost reached statistical significance, which was considered to have contributed to the small postoperative fracture gap and the small lateral extension distance of the blade when IOFC was performed.
