Abstract

Objective: This study aims to compare the efficacy and safety of Proximal Femoral Nail Anti-Rotation (PFNA) versus Dynamic Hip Screw (DHS) in the treatment of intertrochanteric fractures (IF) in elderly patients. We specifically evaluate perioperative indicators, postoperative hip function, and the rate of internal fixation failure.

Methods: 300 elderly IF patients treated in our hospital from July 2018 to May 2022 were divided into the PFNA group (n = 150), control group (n = 150), PFNA group treated with PFNA, and control group treated with mobility hip screw (DHS). Perioperative bleeding, operation time, postoperative time and hospital time were observed in the two groups: fracture reduction, hip function at 1 and 6 months after surgery, and failure of internal fixation. Observe the postoperative internal fixation failure in the PFNA group.

Results: The intraoperative blood loss, operation time, first postoperative time and hospital time in the PFNA group were less than in the control group (P < 0.05). One month after surgery, the Harris score of the PFNA group was less than that of the control group (P < 0.05); the Harris score was not different at 6 months (P > 0.05). The excellent rate of fracture reduction in the PFNA group was greater than that in the control group (P < 0.05). The failure rate of internal fixation in the PFNA group was less than that in the control group (P < 0.05). By univariate analysis, Sing Index classification, Evans classification, 25 min and underlying disease were risk factors for postoperative internal fixation failure in PFNA patients (P < 0.05). After multivariate Logistic regression analysis, Sing Index grade, Evans classification, and tip distance 25min were independent risk factors for postoperative internal fixation failure in PFNA patients (P < 0.05).

Conclusion: The treatment of elderly IF patients with PFNA has the advantages of small trauma, good fracture reduction, firm internal fixation, low failure rate of internal fixation, and quick postoperative recovery. Sing index classification, Evans classification, and 25min tip distance mainly caused internal fixation failure in patients with PFNA.

期刊介绍： Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured. The main focus of THC is related to the overlapping areas of engineering and medicine. The following types of contributions are considered: 1.Original articles: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine. In particular, the clinical benefit deriving from the application of engineering methods and devices in clinical medicine should be demonstrated. Typically, full length original contributions have a length of 4000 words, thereby taking duly into account figures and tables. 2.Technical Notes and Short Communications: Technical Notes relate to novel technical developments with relevance for clinical medicine. In Short Communications, clinical applications are shortly described. 3.Both Technical Notes and Short Communications typically have a length of 1500 words. Reviews and Tutorials (upon invitation only): Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented. The Editorial Board is responsible for the selection of topics. 4.Minisymposia (upon invitation only): Under the leadership of a Special Editor, controversial or important issues relating to health care are highlighted and discussed by various authors. 5.Letters to the Editors: Discussions or short statements (not indexed).
