Bone metabolism and trauma degree of magnetic-guided intramedullary nail fixation for femoral shaft fracture

摘要

Objective: To explore the effect of magnetic-guided intramedullary nail fixation on bone metabolism and trauma degree in patients with femoral shaft fracture. Methods: A total of 128 patients with femoral shaft fractures who received surgical treatment in the hospital between April 2016 and November 2017 were divided into control group (n=64) and study group (n=64) according to the random number table method. Control group received the traditional intramedullary nail treatment, and study group received magnetic-guided intramedullary nail treatment. The differences in serum levels of bone metabolism indexes and inflammatory factors were compared between the two groups 48 h after surgery. Results: 48 h after surgery, serum bone formation indexes BGP, PⅠNP, PⅠCP and BAP levels of study group were higher than those of control group whereas bone resorption indexes β-CTX, TRACP5b and NTX levels were lower than those of control group; serum inflammatory factors TGF-β, hs-CRP, IL-1β, IL-6 and IL-17 levels were lower than those of control group. Conclusion: Compared with traditional intramedullary nail therapy, magnetic-guided intramedullary nail fixation can more effectively balance the bone metabolism status and reduce the fracture end trauma in patients with femoral shaft fracture.
