The use of pararectus approach for Type 3B Paprosky acetabular defect with intrapelvic cup migration. Case report.

A case of Type 3B Paprosky acetabular defect with intrapelvic cup migration where anterior column plating and cup extraction was done through an abdominal pararectus approach. A male patient 63 years old reported progressive pain and walking disability after five years of cementless THR for right hip AVN. CT pelvis showed loose intrapelvic migrated cup, extensive osteolytic acetabular defects, and pelvic discontinuity. Pararectus approach was used to remove the cup and the head with concomitant plating of the anterior column Conclusion: The pararectus approach is a valid option for intrapelvic cup extraction and pelvic discontinuity fixation.
