Failure analysis of a Ti6Al4V cementless HIP prosthesis

Engineering Failure Analysis, 2007
This work investigates the causes of in vivo fracture of a cementless hip prosthesis model manufactured with Ti6A14V alloy. To this end an assessment of geometric characteristics, a fractographic analysis of the fracture surface, and a microstructural study of the stem material were carried out.

Comprehensive Survival Analysis of Reverse Shoulder Arthroplasty: Do Gender, Age, and Surgical Indication Influence Prosthesis Survivorship?

Haseki Tıp Bülteni
Aim: The parameters such as age, gender, and indication for surgery would have a significant influence on the survival of reverse shoulder arthroplasty (RSA). In this context, we aimed to determine how long patients survive after primary and revision RSA
