Proximal femoral nail antirotation for femoral intertrochanteric fractures with lateral wall integrity and lateral wall risk

doi:10.12307/2023.903

Abstract

Abstract: BACKGROUND: For elderly patients with traumatic hip fractures, the related factors of prognosis are very complex, and the integrity of the lateral wall is one of the influencing factors. It is of important clinical value to understand the effect of lateral wall injury on the prognosis of femoral intertrochanteric fracture.
OBJECTIVE: To evaluate the relationship between the integrity of the lateral wall and hip functional recovery and other outcomes in patients with femoral intertrochanteric fractures.
METHODS: Totally 82 patients with femoral intertrochanteric fractures were screened and all patients received proximal femoral nail antirotation fixation. According to the thickness of the lateral wall, the patients were divided into the lateral wall intact group (n=31) and lateral wall risk group (n=51). The perioperative indexes, weight-bearing time, fracture healing time, hip joint function and range of motion, postoperative pain and complications were compared between the two groups.
RESULTS AND CONCLUSION: (1) The time of hospitalization and the number of fluoroscopies during operation in the lateral wall intact group were significantly lower than those in the lateral wall risk group (P < 0.05), but there was no significant difference in other perioperative indexes. (2) Both groups were able to get down to the ground early after surgery and finally complete weight-bearing, but in the lateral wall risk group, the time of fracture healing was longer; the time of complete weight-bearing was significantly delayed; the Harris score of the last follow-up was lower; the range of motion of hip extension and flexion and neck trunk angle on the affected side were smaller (P < 0.05). (3) There was no significant difference in the incidence of postoperative complications between the two groups, but the overall incidence of complications in the lateral wall intact group was significantly lower (P < 0.05). (4) In summary, after internal fixation of proximal femoral nail antirotation, patients with the intact lateral wall had a relatively better prognosis than those with risk lateral wall.
