Periprosthetic Fractures Around the Acetabulum

Peri-Prosthetic acetabular fractures are rare but challenging Complications related to total hip arthroplasty (THA), especially during revision procedures. Factors contributing to these fractures include poor bone quality, prior implant placement, and increased mechanical stress. Several systems classify these fractures and management strategies differ based on whether the fracture occurs intraoperatively or postoperatively and whether the prosthesis is stable/unstable. Undisplaced fractures may be managed conservatively, while displaced fractures often require surgical intervention, such as open reduction and internal fixation (ORIF), alongside implant revision. The modern porous coated cups along with other reconstruction techniques have improved the outcomes. The complications include non-union, implant loosening, deep infection, dislocation.
