Ex vivo estimation of cementless acetabular cup stability using an impact hammer

Ex vivo estimation of cementless acetabular cup stability using an impact hammer

Highlights • Acetabular cup implants were inserted into 20 bovine bone samples with different cavity diameter. • An impact hammer was designed and was used to measure the impact momentum. • Tangential stability tests were performed. • The AC implant stability and the impact momentum were significant...

Zusammenfassung:Highlights • Acetabular cup implants were inserted into 20 bovine bone samples with different cavity diameter. • An impact hammer was designed and was used to measure the impact momentum. • Tangential stability tests were performed. • The AC implant stability and the impact momentum were significantly correlated (R2 = 0.83).
