Insights
Long-term results for the Judet total-exoprosthesis of the hip (TEP) are disappointing. Complications and declining clinical outcomes were observed, with a cumulative success rate of only 55.1% after 11 years.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Clinical outcomes research
Aim:
Control of the long term results of the Judet-TEP.
Methods:
From 1980-1985 124 Pat. have been operated. The follow up was done in the same collective of 83 patients after 2-6 years and > 6 years.
Results:
The intraoperative complications have been fractures of the femur (19.3%) and the trochanter major (3.6%) and luxation (1.9%). In the follow up time the clinical results declined. The patients complained increasing pain in the thigh (26.5%) and the groin (13.2%). Radiological loosening of the acetabulum occurred especially in the medio-caudal area (61.5%) and in the proximal femur (32.5%). Cranial movement of the cup (31.3%) and varus deviation in the femur (40.9%) predominated. 28 prostheses were revised. After 11 years the cumulative success rate was 55.1%.
Conclusions:
The long term results are disappointing.
