[Ender nailing of per and subtrochanteric fractures. Results and complications]

An evaluation of 84 trochanteric and subtrochanteric fractures, treated with Ender pins in the Department of Orthopaedic Surgery (University of Heidelberg) proved to be of instant success in 66 (78%) cases. A reoperation had to be performed in 10 (12%) cases, in 3 of these reoperation the pins had to be redriven. The use of Ender pins failed in 7 patients, a total hip arhtroplasty became necessary. The mortality was 14%. A third of the cases showed an external malrotation which, however, is of no relevance in older people. The intermedullary fixation with Ender pins is a useful operative procedure. Stable internal fixation can be achieved even in sever trochanteric ans subtrochanteric fractures. In case the form of the fracture, the age and the general condition of the patient are satisfactory, a total hip arthroplasty should be considered.
