Does Surface Topography Play a Role in Taper Damage in Head-neck
Stem taper surface topography was related to damage scores on retrieved head-neck modular junctions; however, it affected CoCr/CoCr and CoCr/Ti couples differently. Clinical Relevance A taper topography of circumferential machining marks with higher peaks appears to enable slower damage progression and, subsequently, a …
(PDF) Modular neck femoral stems | Alister Hart
In primary total hip arthroplasty (THA), dual-modular stems were introduced to better restore hip stability, femoral offset, and leg length. This entry highlights the gathered knowledge about dual-modular stems and related complications in combinations with titanium (Ti) and cobalt-chrome (CoCr) exchangeable necks.
Do ceramic femoral heads reduce taper fretting corrosion in …
Background: Previous studies regarding modular head-neck taper corrosion were largely based on cobalt chrome (CoCr) alloy femoral heads. Less is known about head-neck taper corrosion with ceramic femoral heads. Questions/purposes: We asked (1) whether ceramic heads resulted in less taper corrosion than CoCr heads; (2) what device and patient …

Modular neck stems in total hip arthroplasty: current concepts
In our review we registered 12 cases of neck fracture with a rate of 0.38%. 26,28,37 Traina et al 49 confirm that the failure of modular necks is related to neck offset, stem size (the larger the stem, the higher the risk) and body weight. The authors suggest that in the presence of a high BMI, young male patient, a caput-collum-diaphyseal (CCD ...

Midterm outcomes of titanium modular femoral necks in …
Though Ti-Ti modular junctions are more likely to fracture, their lower potential to generate metal ions makes them less harmful to surrounding soft tissues, compared to Ti-CoCr modular junctions (7,21). To the authors' knowledge, few studies investigated long-term outcomes of a Ti femoral stem with a Ti modular neck.

Corrosion fatigue failure of a high carbon CoCrMo modular …
The presence of a Ti stem coupled to CoCr neck can also produce a fretting-galvanic coupling that can reduce the life of the neck [25, 26]. This is also worsened in the case of the modular hip joint because of the creation of a crevice at the stem/neck junction that can lower locally the pH of the solution, creating a more corrosive environment ...

Complications of Modular Neck-Stems | Musculoskeletal Key
A significantly higher 10-year revision rate of 9.7% (95% CI: 8.8, 10.7) was reported for modular femoral neck-stems as compared to 5.1% (95% CI: 4.9, 5.2) for fixed femoral neck-stems. The main reasons for early revisions in the modular femoral neck-stems were due to loosening/osteolysis, dislocation, and modular neck fractures.
