Methods:80 patients with femoral shaft fractures who were treated in our hospital between May 2011 and December 2016 were collected and divided into control group (n=40) and observation group (n=40) according to random number table, control group received conventional steel plate internal fixation treatment, and observation group received minimally invasive mippo intramedullary nail internal fixation treatment. Differences in serum levels of bone formation indexes, bone resorption indexes, inflammatory factors, and pain mediators and so on were compared between two groups of patients before operation and 1 week after treatment.Results: Before operation, differences in serum levels of bone formation indexes, bone resorption indexes, inflammatory factors and pain mediators were not statistically significant between two groups of patients. After operation, serum bone formation indexes P ICP, BGP, BALP and ALP levels in observation group were higher than those in control group;serum bone resorption indexesβ-CTX and OPG levels were lower than those in control group;serum inflammatory factors IL-1β, IL-6, IL-8 and CRP levels were lower than those in control group;serum pain mediators SP, PGE2 and 5-HT levels were lower than those in control group.Conclusion:Minimally invasive mippo intramedullary nail internal fixation treatment of femoral shaft fractures can promote the bone formation, relatively inhibit bone resorption and cause less traumatic reaction.展开更多

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 indexesβ-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.展开更多

Methods:58 patients with femoral shaft fracture treated in our hospital between December 2011 and December 2015 were divided into observation group and control group by random number table (n=29). Control group received conventional intramedullary nail fixation treatment, and observation group received magnetic navigation intramedullary nail fixation treatment. 24 h after surgery, blood coagulation indexes, enzymology indexes, bone metabolism indexes and angiogenesis indexes were determined;6 months after surgery, bone mineral density levels were determined. Results:24 h after surgery, peripheral blood thrombin time (TT), prothrombin time (PT), and activated partial thromboplastin time (APTT) levels of observation group were significantly higher than those of control group, and serum fibrinogen (FIB), D-Dimer (D-D), lactate dehydrogenase (LDH), creatine kinase (CK), creatine kinase isoenzyme (CKMB), glutamic oxalacetic transaminase (GOT), sex hormone-binding globulin type I (SHBG), collagen cross-linked carboxyl-terminal telopeptide (CTX) and deoxypyridinoline (DPD) content were lower than those of control group while bone gla protein (BGP), insulin-like growth factor (IGF-1), hypoxia-inducible factor-1α (HIF-α), angiogenin 1 (Ang-1), recombinant basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) content were higher than those of control group;6 months after surgery, fracture end bone mineral density (BMD) value of observation group was higher than that of control group. Conclusions:Magnetic navigation intramedullary nail treatment of femoral shaft fracture can more effectively reduce the surgical trauma, improve bone metabolism and increase bone mineral density.展开更多
