Among patients with significant proximal femoral bone deficiency, a modular femoral stem demonstrated favorable clinical and radiographic results at short-term follow-up after revision total hip arthroplasty, according to study results.
Researchers performed a retrospective review of 55 revision total hip arthroplasties in 53 patients with a mean follow-up of 32 months. The researchers categorized preoperative bone loss as Paprosky 3A, 3B and 4, and periprosthetic fractures were classified as Vancouver B2 and B3. Outcome measures included WOMAC and Harris Hip scores.
Study results showed an improvement in WOMAC scores from 46 ± 18 to 70 ± 22 and in Harris Hip scores from 47 ± 15 to 78 ± 15. Harris Hip scores were rated as good to excellent in 52% of patients, fair in 30% of patients and poor in 18% of patients, according to the researchers.
Overall, the researchers identified complications in 17% of patients, which included dislocation, subsidence, infection and periprosthetic fracture.
