[Periprosthetic fracture in hip replacement-risk factors and treatment]

Periprosthetic acetabular fractures primarily pose a problem with cementless implantation techniques and occur in approximately 3.6% of primary and up to 20.9% of revision cases. When a fracture situation exists that affects the integrity of the pelvic columns, stabilization using plate osteosynthesis is necessary, in addition to the implantation of a revision cup. Periprosthetic femoral fractures also primarily occur with cementless techniques and account for 0.4-6.8% of revisions after primary total hip arthroplasty. In addition to the cementless technique, the most common risk factors for the development of PFF are a minimally invasive, ventral approach, female gender, poor bone quality, age > 75 years, and revision surgery.

Depending on the degree of risk to the stability of the implant, conservative or surgical treatment can be carried out using osteosynthesis, stem replacement or a combination of both procedures.
