Failures with the Judet noncemented total hip.

Area of Science:

• Orthopedic surgery
• Biomaterials science
• Medical device engineering

Background:

• Total hip arthroplasty (THA) is a common procedure for hip joint issues.
• Noncemented implants aim to improve bone integration and longevity.
• The Judet prosthesis is a specific design for THA.

Purpose of the Study:

• To report primary failures associated with noncemented Judet total hip arthroplasties.
• To identify specific complications and their frequencies.
• To evaluate the overall suitability of the Judet design for noncemented applications.

Main Methods:

• Retrospective analysis of 36 cases using noncemented Judet THA.
• Documentation of all primary failures, including dislocations, migrations, and fractures.
• Recording of reoperation rates and reasons for reoperation.

Main Results:

• A significant reoperation rate of 11/36 (30.5%) was observed.
• Primary failures included dislocations (2/36), migrations (4/36), and fractures (9/36).
• Steep cup inclination was associated with dislocations, migrations, and painful hips.

Conclusions:

• The noncemented Judet total hip arthroplasty demonstrated a high rate of primary failures.
• Complications such as dislocations and fractures indicate design or surgical technique limitations.
• The Judet prosthesis is not recommended for noncemented total hip arthroplasty.
