Femoral impaction bone grafting with the Elite Plus stem.

Area of Science:

• Orthopedic Surgery
• Biomaterials Science

Background:

• Revision hip arthroplasty is complex, often requiring bone reconstruction.
• Impaction grafting with allograft is a technique used to address bone stock defects.
• The Elite Plus system is one option for femoral stem implantation in revision cases.

Purpose of the Study:

• To evaluate the outcomes of impaction grafting with the Elite Plus femoral stem.
• To assess graft incorporation and bone healing after revision hip arthroplasty.
• To determine the failure rate and complications associated with this technique.

Main Methods:

• A prospective study of 19 hips undergoing revision hip arthroplasty.
• Utilized the Elite Plus femoral stem with irradiated allograft for impaction grafting.
• Patients were followed for an average of 33 months with radiographic and clinical assessments.
• Bone stock loss was graded using the Endo-Klinik classification.

Main Results:

• Graft incorporation was observed in 32% of cases.
• No significant trabecular remodeling or cortical repair was evident radiographically.
• A high failure rate was noted, with 4 patients requiring revision surgery.
• Complications were more frequent in patients with Endo-Klinik grade 3 bone loss.

Conclusions:

• Impaction grafting with the Elite Plus system demonstrated a high failure rate in revision hip arthroplasty.
• The technique appears less successful in patients with substantial bone stock loss.
• Further research is needed to improve outcomes for complex revision hip surgeries.
