[Preoperative C-reactive protein level has a dose-response relationship with postoperative complications in elderly patients with femoral neck fracture].

OBJECTIVE: To analyze the association of preoperative C-reactive protein (CRP) level with postoperative complications in elderly patients undergoing surgeries for femoral neck fracture. METHODS: We retrospectively analyzed the data of 147 elderly patients (median age 80 years; 73.5% of the patients were female) undergoing surgeries for femoral neck fracture. According to preoperative CRP level, the patients were divided into normal CRP (< 10 mg/L) group (31 patients), mild elevation group (CRP level of 10-40 mg/L; 51 patients), and severe elevation group (CRP ≥40 mg/L; 65 patients). The association of preoperative CRP levels with postoperative complications was analyzed. RESULTS: : 1.47-16.26), respectively. CONCLUSIONS: Preoperative CRP level has a dose-response relationship with complications in elderly patients following arthroplasty for femoral neck fracture, and the patients with a preoperative CRP level ≥40 mg/L are exposed to a significantly increased risk for postoperative complications by 3.89 folds compared with the patients with a normal CRP level.
