Treatment algorithm of acetabular periprosthetic fractures

Area of Science:

• Orthopedic Surgery
• Arthroplasty
• Trauma Surgery

Background:

• Periprosthetic acetabular fractures are infrequent complications of total hip arthroplasty (THA).
• Management is challenging due to a lack of established treatment guidelines.
• Fractures can occur intraoperatively or postoperatively due to trauma or pelvic discontinuity from osteolysis.

Purpose of the Study:

• To review the epidemiology, etiology, and classification of periprosthetic acetabular fractures.
• To present a diagnostic and therapeutic algorithm for managing these fractures.
• To consolidate current knowledge for improved clinical decision-making.

Main Methods:

• Literature review of periprosthetic acetabular fractures.
• Analysis of existing classification systems.
• Development of a diagnostic and therapeutic algorithm based on fracture stability and implant integrity.

Main Results:

• Fracture stability is the key determinant for treatment strategy (operative vs. non-operative).
• Unstable fractures necessitate surgical intervention for component stability and biological fixation.
• A variety of surgical techniques exist, tailored to specific fracture patterns.

Conclusions:

• Effective management requires careful assessment of fracture stability and implant status.
• The proposed algorithm aims to guide treatment decisions for periprosthetic acetabular fractures.
• Further research may lead to standardized guidelines for these rare but significant complications.
