A retrospective study was performed of forty-nine patients (fifty
fractures of the femoral neck) who had Parkinson disease and who had had an
endoprosthetic replacement of the femoral head. The average age of the
patients was seventy-four years (range, forty-seven to ninety-two years).
All of the fractures were Garden Stage III or IV. An anterolateral surgical
approach was used in twenty-five hips; a posterior approach, in twenty
hips; and a transtrochanteric approach, in five hips. An adductor tenotomy
was required in five patients to release an adduction contracture. Ten
patients died by the sixth postoperative month. The remaining thirty-nine
patients were followed for a minimum of two years (average, 7.3 years).
Common postoperative complications were infection of the urinary tract (20
per cent) and pneumonia (10 per cent). There was only one dislocation. At
the time of writing, nineteen (80 per cent) of the surviving patients could
walk.
