D Reimplantation Acetabulum

Principles of Acetabular reconstructionRevision Acetabulum Post Paprosky Type IIIC

 

Restore centre of rotation
Restore acetabular integrity
Component containment
Secure fixation


Preoperatively planning


Know components in situ (esp if leaving femur)
Quantify and grade bone defects
Beware intrapelvic cement / cup (angiogram)

C Approach and Implant Removal

Pre-operative Planning


CT / quantify bone loss
X match 4 units
Cell saver
Anaesthetic review
Bone graft (cortical, cancellous)
Component removal gear

- extraction gear for femur / liners

- cement removers for cemented femur

- curved osteotomes for cemented cup

- X-plant for uncemented cup
Revision long stem femoral implants
Revision acetabular implants including cages
