Custom 3D-printed split-type triflange implants for severe acetabular defects: mid-term clinical outcomes and biomechanical insights from finite element analysis
Custom 3D-printed split-type triflange prostheses achieve excellent midterm functional restoration and biomechanical stability in Paprosky 3B defects. Key advantages include precise hip rotation center reconstruction, favorable stress distribution, and reduced intraoperative morbidity. Early partial weight-bearing is safe, though high-impact activities should await radiographic confirmation of osseointegration. Long-term validation of durability is warranted.
