[Traumatic indications for total hip joint prosthesis].

In the years 1978-1986 the authors implanted 207 total prostheses in patients with the fracture of the femoral neck or after the fractures in the area of the hip joint. 50 patients were operated on for an acute fracture of the neck. The surgical technique in these indications does not differ on principle from the surgical technique of coxarthrosis. They point out a higher number of some peroperative complications. They checked 141 patients with and average follow-up of 47 months. In 4.2 per cent of late complications they reported roentgenological symptoms of loosening. Reoperation because of the loosening of the acetabular component was inevitable in 2.9 per cent of patients. All these cases fall into the group of patients in which the total hip arthroplasty was performed after the fractures of the acetabulum. In no patient it was necessary to reoperate the femoral component. Within the check up the patients underwent roentgenological examination and the result was assessed by the method according to Harris. In total, excellent result was reported in 43.2 per cent of patients, good result in 29.8 per cent, fair result in 14.2 per cent and poor result in 12.8 per cent of patients. With regard to a low number of complications and very good results of the evaluation according to Harris the authors consider total hip arthroplasty in the treatment of post-traumatic conditions for fully indicated. Total hip arthroplasty is indicated also in acute fractures of the femoral neck in which it brings in a short time interval good functional results with minimum complications. A group at risk is represented by patients operated on after the fractures of acetabulum.
