Abstract:
Periprosthetic acetabular fractures (PPAF) are a rare but increasingly relevant complication following total hip arthroplasty. The management is complex and requires expertise in fracture treatment and revision arthroplasty. The treatment planning is based on the morphological fracture characteristics according to the column concept (Letournel), the extent of bone defects (fracture-related or pre-existing), the stability of the acetabular component and patient-related factors. This review article presents a practice-related algorithm on how to approach PPAFs. In addition to the preoperative diagnostics, established classification systems, surgical approaches and treatment strategies for various fracture scenarios are also presented.
