Comparison of Proximal Femoral Nail Antirotation and Dynamic Hip Screw Internal Fixation on Serum Markers in Elderly Patients with Intertrochanteric Fractures
2019
OBJECTIVE: To compare effect of proximal femoral nail antirotation (PFNA) and dynamic hip screw (DHS) internal fixation on serum inflammatory mediators (CRP, IL-1, IL-6 and TNF-α), myocardial injury markers (cTnT, CK-MB), and Myo-heart failure marker (BNP) in elderly patients with intertrochanteric fractures. STUDY DESIGN: Experimental study. PLACE AND DURATION OF STUDY: Department of Orthopedics, The Second Affiliated Hospital of Xuzhou Medical University, China, from January 2016 to February 2018. METHODOLOGY: A total of 114 patients with intertrochanteric fractures were randomly divided into Group A and Group B, with 57 cases in each group. Group A was treated with PFNA and Group B with DHS internal fixation. Serum CRP, IL-1, IL-6, TNF-α, cTnT, CK-MB, Myo, BNP and surgical indication were compared. RESULTS: Operation time and weight-bearing time in Group A were shorter than Group B (both p<0.001). Intraoperative blood loss and postoperative drainage volume in Group A were lower than Group B (both p<0.001). On the 7ᵗʰ day after surgery, serum CRP, IL-1, IL-6, TNF-α, cTnT, CK-MB, Myo and BNP in Group A were lower than Group B (all p<0.001). CONCLUSION: Compared with DHS, PFNA effectively reduced serum inflammatory mediators with less damage to cardiac function and myocardium in elderly patients with intertrochanteric fractures.
