Does a Dual Mobility Cup Lower the Risk of Dislocation After THR?
The dislocation rate of hip prostheses in dogs is reported to range from 4-15%, representing the most common short-term complication and source of frustration for the owner and the surgeon. This is especially true in large and giant breed dogs, usually requiring revision surgery.

Objective:
Inform veterinary professionals about
- Implant Characteristic
- Surgical technique
- Indications for Dual Mobility Cup
- Long-term performance of the Dual Mobility Cup in dogs with a high risk of luxation after THR and
Design:
Retrospective, single-center study. 105 THR were performed using the Zurich Cementless Total Hip System with the Dual Mobility cup.
Results:
Results of 105 cases demonstrated a low complication rate, including dislocation, of only 1% (1/103).
Conclusion:
The Dual Mobility cups may be an alternative to standard single-bearing cups in dogs reported being at high risk for luxation in both revision and primary arthroplasty. The complication rate, including dislocation, is relatively low in the cases reported in this study (1/103, 1%).
