[Periprosthetic acetabular fractures: classifications, treatment and challenges]

Area of Science:

• Orthopaedic Surgery
• Trauma Surgery
• Biomedical Engineering

Context:

• Periprosthetic acetabular fractures (PPAF) are a growing concern, linked to the rising number of total hip arthroplasties (THA) and implant longevity.
• Existing literature on the surgical management of PPAF is limited, highlighting a need for comprehensive reviews and treatment guidelines.

Purpose:

• To provide an overview of PPAF, critically reviewing current literature.
• To outline the essential surgical treatment strategies for PPAF.

Summary:

• Surgical treatment of PPAF is complex due to pelvic instability and compromised bone stock, requiring restoration of biomechanical stability for secure acetabular cup fixation.
• An interdisciplinary approach involving orthopaedic and trauma surgeons is crucial, particularly for elderly patients with comorbidities and poor bone quality.

Impact:

• Highlights the technical challenges and necessity of specialized surgical expertise for PPAF.
• Emphasizes the importance of collaborative, goal-oriented interdisciplinary care for achieving optimal, individualized patient outcomes in PPAF management.
