Beskrivelse

Complex acetabular defects with associated infection as well as multiple revision procedures remain a significant reconstructive challenge due to compromised bone stock, altered anatomy, and increased risk of recurrent infection. Custom triflange implants have been used to restore pelvic stability in severe bone loss; however, conventional metallic constructs may present limitations in previously infected environments, including challenges with imaging assessment and biomechanical load transfer. Patient-specific implants manufactured from Poly Ether Ketone Ketone (PEKK), a high-performance polymer with mechanical properties closer to cortical bone, may offer an alternative reconstructive strategy.
