PFNA-II Internal Fixation Helps Hip Joint Recovery and Improves Quality of Life of Patients with Lateral-Wall Dangerous Type of Intertrochanteric Fracture

Objective To analyze the effect of PFNA-II internal fixation on hip joint recovery and quality of life (QOL) in patients with lateral-wall dangerous type of intertrochanteric fracture.Methods One hundred and twelve patients with lateral-wall dangerous type of intertrochanteric fracture who underwent surgical treatment in our hospital from May 2017 to May 2019 were selected as the participants of the study. Based on the treatment method, all the enrolled patients were divided into two groups: proximal femoral nail antirotation (PFNA group; n = 59) who received closed reduction and minimally invasive PFNA internal fixation and dynamic hip screw group (DHS; n = 53) who received internal fixation. The clinical indicators, curative effect, hip function score, pain degree, postoperative QOL score, and complications were compared between the two groups.Results The operation time, intraoperative blood loss, postoperative drainage volume, and the incidence of postoperative complications in PFNA group were statistically lower than those in DHS group ( P < 0.05). The curative effect in PFNA group was notably better than that in DHS group. There were no significant differences in scores of hip function, visual analogue scale (VAS), and QOL between the two groups before operation ( P > 0.05). However, the hip function score and QOL score increased in both groups after surgery, and the increase was more significant in the PFNA group, while the VAS score decreased in both groups, and the decrease in PFNA group was more significant ( P < 0.05).Conclusion PFNA internal fixation for the treatment of lateral-wall dangerous type of intertrochanteric fracture has the advantages of short operation time, less intraoperative blood loss, effective improvement of hip joint function, and fewer postoperative complications, which is worthy of clinical application.
