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.

Objective To study the effect of short course of mini dose hormonal application after long-segment spinal fusion using allograft bone in scoliosis.Methods A retrospective study was made in 106 patients with scoliosis,who underwent posterior spinal fusion during May,2004 to Jan,2007 in our hospital.These patients were divided into two groups.Hormone group,68 cases,were 13 to 28 years old with a mean age of 16.5 years old.The average fused segments were 9.0 vertebrae(range from 7 to 12 vertebra).Glucocorticoid was used after operation about 5 to7 days.No hormone group,38 eases,were 14 to 30 years old with a mean age of 17.5 years old.The average fused segments also were 9.0 vertebrae(range from 6 to 12 vertebra).No glucocorticoid was used after operation.All patients received spinal instrumentation with TSRH system and spinal fusion with allograft bone.The temperature,white blood cell(WBC),ESR,drainage and complications between two groups after operation were comparative analyzed.Result Between two groups,the variance of the figures of the temperature,WBC,ESR and drainage are statistically significant.There was less complication in hormone group than that in no hormone group.Conclusion After the operation of the segments spinal fusion by allograft bone,using mini-close glucocorticoid by short course of treatment can significantly decrase some complications and ensure spinal fusion.
