Fracturas periprotésicas distales de fémur

Resum

The number of Total Knee Replacement surgeries performed in our country increases annually, so it is expected that so will increase their complications. Among them, Periprosthetic distal femoral fractures, which we deal with in this review article. The most important risk factors are both, osteoporosis and anterior femoral notch (although this one is still controversial). Obesity has been shown not to be a risk factor. There are no solid studies yet showing significant differences related to pseudoarthrosis between locked plates and intramedullary nails. Recent reviews even determine that both achieve similar stability rates. Megaprostheses (tumoral prostheses) are beginning to be used more and more in this type of fractures. The key factor when choosing the best treatment option for periprosthetic distal femoral fractures is to determine the state of the prosthesis, the amount of distal bone stock and the degree of displacement.
