Background Prevention of dislocation after primary total hip arthroplasty (THA) begins with
patient preoperative assessment and planning. Methods We performed a literature search to …

Introduction This review critically examines the efficacy of dual-modular stems in primary
total hip arthroplasty. Given the variability and non-comparability of certain femoral stem …

Femoral stem modularity in hip replacement was first developed to connect a ceramic head
to the stem, then extended to metal heads using the Morse taper principle. Is it a good thing …

Modular neck (MN) implants can restore the anatomy, especially in deformed hips such as
sequelae of development dysplasia. Early designs for MN implants had problems with neck …

Background and Objectives: Increased revision rate of dual-modular (DM) femoral stems in
primary total hip arthroplasty (THA) because of modular-neck breakage and adverse local …

Total hip arthroplasty (THA) is one of the most successful elective operations in orthopedic
surgery for improving pain and functional disability in patients with end-stage joint disease …

Purpose Neck modularity was introduced to improve total hip arthroplasty (THA) accuracy,
but it has been associated with early breakages and corrosion issues. In our hospital …

Low friction between DLC coating and Ti single bond6Alsingle bond4V alloy was
investigated under fretting conditions on a fretting-wear testing machine. The results …

Background Femoral stems with bimodular (head-neck as well as neck-body) junctions were
designed to help surgeons address patients' hip anatomy individually. However, arthroplasty …

Introduction Breakage of exchangeable-neck (EN) and adverse local tissue reactions
(ALTRs) to neck–stem junction (NSJ) damage products are responsible for increasing the …
