[Treatment of per- and subtrochanteric femoral fractures in conjunction with coxarthrosis].

When both a coxarthrosis and a sub- or pertrochanteric fracture of the femur are simultaneously present, it is, as a rule, most difficult to carry out a closed reduction of the fracture on the extension table. In almost all cases, an open reduction has to be performed. When such an open reduction is necessary, this should not give reason to dispense with the advantages offered by the Ender nailing method and select another technique of osteosynthesis. An early mobilisation, which is of particular importance to old patients, can be achieved best by the aforementioned osteosynthesis. On the other hand, the implantation of a resection prosthesis as the logical treatment of a coxarthrosis coinciding with a per- or subtrochanteric fracture of the femur is in most cases out of question when the patient has not been sufficiently prepared, and should therefore be reserved for surgical intervention at a later date.
