Summary
Impaction bone grafting for total hip revision demonstrated potential complications, including stem malposition and fractures. Careful surgical technique may prevent most adverse outcomes in revision hip arthroplasty.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Total hip revision surgery presents challenges, particularly concerning bone stock restoration.
- Impaction bone grafting is a technique used to augment bone defects during revision arthroplasty.
Purpose of the Study:
- To evaluate the outcomes and complications of impaction bone grafting in total hip revision.
- To assess the safety and efficacy of using morselized allograft bone with a specific femoral stem design.
Main Methods:
- A retrospective review of 26 total hip revisions in 25 patients using impaction bone grafting.
- Morselized allograft bone and a collarless, polished, tapered femoral stem were utilized in all cases.
- Surgical duration, blood loss, transfusion requirements, and hospital stay were recorded.
Main Results:
- The average patient age was 68 years, with an average of 9 years since the last surgery.
- Complications included stem varus placement (3 hips), femoral fractures (4 hips), and one dislocation.
- Average subsidence was 0.6 cm.
Conclusions:
- Impaction bone grafting is a viable option for bone restoration in total hip revision.
- A significant complication rate was observed, suggesting potential for improvement through surgical technique optimization.
- Most complications encountered in this series may be preventable with meticulous surgical execution.
