[Acetabuloplasty in adult hip dysplasia using femoral head graft].

INTRODUCTION

acetabular dysplasia in adults represents a therapeutic challenge due to progressive joint instability, pain, and functional limitation. This article presents a case series using acetabuloplasty with autologous femoral head graft, combined with total hip arthroplasty, as a treatment option for adult patients with severe acetabular dysplasia and osteoarthritis.

MATERIAL AND

METHODS

a prospective case series was carried out between 2023 and 2024 at Cancun General Hospital. Five adult patients diagnosed with advanced hip dysplasia (Crowe II-IV) and Tönnis grade IV coxarthrosis were included. All patients underwent cemented dual-mobility total hip arthroplasty combined with acetabuloplasty using the autologous femoral head as graft material. Demographic characteristics, surgical approach and outcomes at 12-month follow-up are reported.

RESULTS

the five patients (three females and two males, mean age 57 years) showed significant functional improvement. All patients achieved standing and assisted walking at four weeks, independent walking at 8-10 weeks, and restoration of functional mobility arcs. Harris hip score improved from < 70 preoperatively to > 90 points at final follow-up.

CONCLUSIONS

acetabuloplasty with autologous femoral head graft combined with dual-mobility total hip arthroplasty is a reliable procedure, providing joint stability, early rehabilitation and improved quality of life. Although limited by sample size, this case series supports the utility of this technique as a valid therapeutic option in adult hip dysplasia with osteoarthritis.
