Thrust plate hip prosthesis: early results of a new concept in the femoral component of total hip arthroplasty

Abstract

Objectives: To assess the results of a new and different concept of extramedullary total hip arthroplasty, namely the thrust plate prosthesis (TPP). Methods: Thirty-five hips (6 bilateral) of 29 patients (18 females, 10 males) were treated by TPP. The mean age was 54.4 years (range 26 to 79 years). Etiologic factors included primary coxarthrosis (n=14), avascular necrosis (n=7), developmental dysplasia of the hip (n=5), coxarthrosis due to a trochanteric fracture (n=4), and fracture (n=3) and nonunion (n=1) of the femoral neck. Uncemented Protek expansion cup was used in all but four patients who received cemented CCB cup. Patients were evaluated preoperatively and postoperatively by the Harris hip score. The mean follow-up period was 17.6 months (range 6 to 36 months). Results: One patient was excluded as TPP was replaced by a Leinbach type prosthesis because of a femoral shaft fracture detected during the rehabilitation period. Deep vein thrombosis was observed in one patient. The mean preoperative Harris score was 47.2, being 88.7 at 6 months, 93.2 (23 hips) at 12 months, 96.9 (17 hips) at 18 months, and 97.7 (14 hips) at 24 months. Neither loosening nor infection was encountered during the follow-up period. Conclusion: Thrust plate prosthesis seems to have many advantages, including its applicability both to the metaphyseal region without reaming the medullary canal and to narrow and angulated femora, prevention of bone loss, allowing early motion, and biomechanical compatibility, making it a reliable method for total hip replacement.
