Journal: Acta Orthopaedica Belgica
Treatment Used: Birmingham Hip Resurfacing and Total Hip Arthroplasty
Number of Patients: 127
MediFind Summary

Summary: This study tested the safety and efficacy of using Birmingham hip resurfacing and total hip arthroplasty to treat patients with hip osteoarthritis.

Conclusion: The study found that both groups achieved excellent midterm clinical and radiographic results with 100% survival rates.


The aim of this study is to determine the functional outcome and midterm survival rates of the Birmingham Hip Resurfacing and Birmingham Total Hip Arthroplasty. This retrospective, observational study included 150 surgeries (46 resurfacing procedures and 104 arthroplasty procedures) performed in 127 patients from 2005 to 2012. The Resurfacing and Arthroplasty study groups were evaluated with clinical (Harris Hip Score and Hip Disability and Osteoarthritis Outcome Score) and radiological follow-up. Cobalt and chromium levels were measured via blood samples. No revisions were required in either study group. Femoral stem osteolysis was observed in three patients in the Arthroplasty group. No osteolysis was observed in the Resurfacing group. Significantly higher clinical scores were observed in the Resurfacing group (p=0.04 and p=0.04, respectively). The average level of metal ions were similar in both groups. Both groups showed excellent midterm clinical and radiographic results with 100 percent survival rates. Additional follow-up is required to monitor future changes in blood metal ion levels.
