Abstract:
BACKGROUND:Clinical treatment of epicondyle fractures and intercondylar comminuted fractures is quite tricky due to instability and spread to the articular surface. Common complications contained bone delayed union, nonunion, broken nails and broken boards. Internal fixation for fractures is various, but reasonable choice for clinical fixation plays a decisive role for repair of fractures.
OBJECTIVE:To explore the repair effects of various fixation methods on femoral condyle fracture from different aspects such as fracture type, bone healing, functional recovery and biomechanics.
METHODS:First author searched PubMed database and China National Knowledge Infrastructure for articles about various fixation methods in repair of femoral condyle fracture published from January 2000 to April 2014. Key words were“femoral condyle fracture, internal fixation, biomechanics, load-displacement, axial stiffness, horizontal shear stiffness”. Total y 142 articles were retrieved, but 39 articles met the inclusion criteria.
RESULTS AND CONCLUSION:Femoral condyle fracture caused the damage to normal anatomic structure of knee join, changed normal anatomical axis and the mechanical axis of knee joint. Therefore, anatomic reduction and rigid internal fixation are necessary. During treatment, the advantages and disadvantages of various fixation methods should be known. It is necessary to ful y evaluate the type of intercondylar fractures of the femoral condyle and soft tissue injury. According to biological characteristics of the human body and mechanical property, internal fixation device should be reasonably used. Individual treatment programs should be provided. Thus, the occurrence of postoperative complications should be reduced utmostly, resulting in a satisfactory repair outcome.
