Summary

This study tests custom-made, 3D-printed hip implants for 15 adults whose previous hip replacements failed due to severe bone loss or infection. The implants are designed from CT scans to fit each person's unique bone damage. Researchers will track complications, pain, mobility, and implant survival for up to 3 years to see if this personalized approach improves outcomes.

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of adult individuals (minimum age: 18 years) consecutively treated for revision hips (non-oncological reasons) requiring a custom-made acetabular implant. Patients will be enrolled in 4 tertiary centers (multicenter prospective study). Patients eligible for this implant are those with severe acetabular bone damage Paprosky 3 (loss of the superolateral part and one of the two ventro-caudal walls).
