Abstract
Objectives:
This paper aims to present the outcome of acetabular reconstruction with bone grafts augmentation for eight-years neglected central hip dislocation post femoral bipolar hemiarthroplasty.
Methods/Case Presentation:
A 29-year-old woman complained of pain on right hip that worsen 3 months ago. Patient had history of THA Bipolar surgery eight years ago. After the first surgery, patient walked with 2 crutches. Physical examination showed shortening for 2 cm. X-ray showed dislocation of hip prosthesis to the superomedial. Patient was then diagnosed with central dislocation right hip post THA bipolar and protrusion of right acetabulum hip. Then, she was planned for total hip replacement with synthetic bone grafts, bone cement augmentation, and cup-cage construction. The surgery went successful. Patient still underwent for rehabilitation.
Results/Clinical Discussion:
Reconstructing acetabular bone loss can be challenging and depend on the type of defect. Autologous bone fulfils all three ideal requisites of a bone graft, being osteoconductive, osteoinductive and osteogenic. Moreover, the autograft is non-immunogenic and cannot transmit infectious agents unless contaminated during surgery. However, there were also risk with applying graft such as discomfort at the donor site, increased blood loss, prolonged surgery duration, risk of donor site infection, and very limited availability of grafts. Due to scarce availability, we also combining with bone augmentation to improve the outcome of surgery.
Conclusion:
In this eight-years neglected central hip dislocation post femoral bipolar hemiarthroplasty, we successfully managed the case with acetabular reconstruction with bone grafts augmentation.
