Introduction: Acetabular fracture-dislocations are complex injuries that, if misdiagnosed or mismanaged, can lead to avascular necrosis and early total hip arthroplasty (THA) failure. Case Report: A 16-year-old male with a neglected acetabular fracture-dislocation underwent an ill-planned THA, with the cup placed in fracture callus, which was removed the next day. He later presented in a Girdlestone-like state. Imaging and 3D modeling revealed a malunited posterior wall and column fracture. A staged approach - corrective osteotomy with fixation followed by revision THA - was performed. Result: At 10 months, he achieved excellent function and stable radiographic reconstruction. Conclusion: Early recognition, detailed pre-operative planning, and 3D-assisted individualized surgical strategies are vital for successful reconstruction of neglected or failed acetabular fracture-dislocations.
