Fixation of the endoprosthesis stem with muracito cortical bone allograft

Endoprosthesis replacement of the femoral head for neck fractures in elderly and senile patients is the method of choice [1]. However, when using it, a number of significant factors should be taken into account. Bone tissue in this category of patients, as a rule, is porotic and characterized by increased fragility, the medullary canal is significantly expanded. Therefore, after the operation and subsequently, loosening of the endoprosthesis often occurs with all the ensuing consequences, such as pain, swelling of the limb, instability in the hip joint, inflammation, paraarticular calcifications. To ensure stable fixation of the endoprosthesis stem in the medullary canal of the femur, special cement, fragmented spongy auto- or allogeneic bone, hydroxyapatite glue, etc. are used [2–6]. However, these measures do not exclude the occurrence of a suppurative process, the development of micromobility, loosening and instability of the endoprosthesis.
