Susceptibility to local infection in biological internal fixation

摘要: Resistance to local infection after fracture fixation with plate osteosynthesis may be influenced by the implantation technique. It is known that extent of surgical approach bone can compromise defence capacity. We have investigated susceptibility a bacterial challenge in rabbit tibiae using either open for ‘biological’ internal standard 2.0 dynamic compression plates or method minimally invasive (MIPO), percutaneous, tunnelling insertion technique preserving integrity overlying soft tissue. After wounds had been closed, various concentrations Staphylococcus aureus were injected direct vicinity implants. The rate was 38.5% and MIPO technique, 25%. This difference not statistically significant (P > 0.05) suggesting resistance associated at least equivalent osteosynthesis.
