Bulk femoral-head autografting in uncemented total hip arthroplasty for acetabular dysplasia

Acetabular dysplasia causes difficulty in achieving adequate coverage of the acetabular component during total hip arthroplasty (THA). Bulk femoral-head autografting is one technique that has been used to achieve better coverage of the acetabular component. Long-term follow-up studies have shown a significant failure rate when this technique has been used in conjunction with a cemented acetabular component; however, with uncemented components, early results have been encouraging. In our study, 15 patients with acetabular dysplasia underwent uncemented THA, during which bulk femoral-head autografts were used. At an average follow-tip of 10 years, no cases required revision, and radiologically, the bone graft had united. Our results support the use of bulk femoral-head autografting in patients with acetabular dysplasia requiring hip arthroplasty.
