Effect of different internal fixation devices on intertrochanteric fractures

Aims: To analyze the postoperative recovery effects of different internal fixations on intertrochanteric fractures, so as to select the best fixation method for clinical practice.

Methods: This is a retrospective analysis. A total of 100 patients with intertrochanteric fractures hospitalized at The Affiliated Tai'an City Central Hospital of Qingdao University from March 2022 to March 2024 were grouped according to the treatment method. 43 patients received intramedullary fixation in an observation group and 57 patients underwent extramedullary fixation in a control group. We collected data including operation time, total length of the surgical incision, hospitalization time, postoperative reexamination rate, occurrence of reduction loss, coxa vara, infection, non-union of fractures, and postoperative imaging of the patients.

Results: The total response rate of the observation group was 88.37%, which was statistically higher than that of the control group (85.96%, P < 0.05). The mean Harris hip joint score at six months after intervention was 88.3±5.3 in the observation group, significantly higher than 62.3±4.2 in the control group (P = 0.006). In terms of inflammatory reaction, the observation group showed significantly decreased serum concentrations of high-sensitive C-reactive protein and procalcitonin at one week after surgery compared to the control group (P < 0.001). After intervention, the observation group demonstrated significantly higher balance ability than the control group (P < 0.05).

Conclusion: Intramedullary fixation for intertrochanteric fractures can significantly promote the postoperative functional recovery and fracture healing of patients, presenting a better fixation effect.
