Total Hip Arthroplasty Implant with Osteosynthesis Cutaway (8 Bodies)
8-body orthopedic biomechanics assembly with coronal cutaway through the pelvic acetabulum, proximal femur bone, titanium acetabular shell, and UHMWPE liner exposing the Ti-6Al-4V stem, 12/14 Morse taper, and Ø36 mm Biolox ceramic head.
Total hip arthroplasty (THA) restores joint kinematics by anchoring a tapered Ti-6Al-4V stem inside the femoral medullary canal and a porous titanium shell inside the pelvic acetabulum. This 8-body cutaway model includes a lateral compression osteosynthesis plate with four bicortical screws and full boolean cavities in both bone structures and screw channels.
1. Geometry & FEA Mesh
- •8 independent solid bodies: Ti-6Al-4V femoral stem, Biolox ceramic femoral head (Ø36 mm), UHMWPE liner (cutaway), titanium acetabular cup (cutaway), 2 cancellous bone screws, pelvic acetabulum bone (cutaway), proximal femur bone (cutaway), and lateral osteosynthesis plate with 4 cortical screws.
- •Zero CAD Collisions Gate verified: 0.000 mm³ overlap across all 8 bodies.
2. Loads & Boundary Conditions
- •Conical Morse taper bore in the ceramic head, spherical articulation clearance in the UHMWPE liner, and exact screw/stem channels in the bone solids.
3. Simulation Results & Findings
- ✓All 8 prosthetic and bone components can be toggled independently in the WebCAE model tree.
Demonstrates WebCAE's application to medical device engineering, orthopedic implant design, and biomechanical CAD-to-FEA workflows.
