Titanium (Ti) alloys have been proven to be one of the most suitable materials for
orthopaedic implants. Dual modular stems have been introduced to primary total hip …

Acetabular cups, which are among the most important implants in total hip arthroplasty, are
usually made from titanium alloys with high porosity and adequate mechanical properties …

In total hip arthroplasty, excessive acetabular cup deformations and altered strain
distribution in the adjacent bone are potential risk factors for implant loosening. Materials …

Deformation of the acetabular shell at the time of surgery can result in poor performance and
early failure of the hip replacement. The study aim was to validate an ATOS III Triple Scan …

Seating a cementless acetabular cup via impaction is a balancing act; good cup fixation
must be obtained to ensure adequate bone in‐growth and cup apposition, while acetabular …

Aims Cementless acetabular components rely on press-fit fixation for initial stability. In
certain cases, initial stability is more difficult to obtain (such as during revision). No current …

To gain initial stability for cementless fixation the acetabular components of a total hip
replacement are press-fit into the acetabulum. Uneven stiffness of the acetabular bone will …

The hip joint is subjected to cyclic loading and motion during activities of daily living and this
can induce micromotions at the bone-implant interface of cementless total hip replacements …

In this study Raman (RS) and Fourier Transform Infrared (FT-IR) spectroscopic techniques
were exploited to study 11 retrieved liners made of remelted highly cross-linked …

Insufficient primary stability of acetabular hip cups is a complication resulting in early cup
loosening. Available cup designs vary in terms of wall thickness, potentially affecting implant …
