Brief summary

In this study, we aim to develop a statistical shape model and use it to reconstruct the shape of acetabula with severe defects (Paprosky 3a-3b). This will allow us to visualise and assess the morphology of the missing bone. In future studies we will use the obtained results to improve the design of acetabular implants for revision surgery.

Inclusion criteria

Trainings dataset for statistical shape model: * Patients where a bilateral CT of the hip was performed with unilateral pathologies. * We aim to include an equal amount of scans from each gender and varying ages. Dataset of defect acetabula used for reconstruction: * Patients who received a CT scan of the hip after removal of a primary/revision implant (e.g. patients where debridement was performed due to infection.) * Patients where the defect can be classified as a Paprosky 3a or 3b defect.
