How to proceed with a clinically asymptomatic modular Metha® Ti alloy stem with dual taper CoCr neck adapter in case of acetabular revision? To systematically answer this question the status of research and appropriate diagnostic methods in context to clinically symptomatic and asymptomatic dual taper stem-neck couplings has been evaluated based on a systematic literature review. A retrieval analysis of thirteen Metha® modular dual taper CoCr/Ti alloy hip stems has been performed and a rational decision making model as basis for a clinical recommendation was developed. From our observations we propose that in cases of acetabular revision, that for patients with a serum cobalt level of > 4 µg/L and a Co/Cr ratio > 3.6, the revision of the modular dual taper stem may be considered. Prior to acetabular revision surgery a systematic diagnostic evaluation should be executed, using specific tests such as serum metal (Co, Cr) ion analysis, plain antero-posterior and lateral radiographs and cross-sectional imaging modalities (Metal Artefact Reduction Sequence Magnetic Resonance Imaging). For an asymptomatic Metha® dual taper Ti alloy/CoCr stem-neck coupling at the stage of acetabular revision careful clinical decision making according to the proposed model should be followed and overreliance on any single examination should be avoided, considering the complete individual differential diagnosis and patient situation.

“…Serum cobalt and chromium ion levels have been used to diagnose taper corrosion. Metal artifact reduction sequence MRI is an excellent diagnostic tool for evaluation of patients with elevated serum cobalt after MoP THA [11], [16], [17], [18]. In the present case, we used MoP articulation at the time of revision surgery and careful follow-up is required for MACC to occur.…”

“…A ceramic head could decrease corrosion products from MACC at the trunnion and taper interface. MACC occurred at the head-neck and neck-stem taper junction in which at least one of the components is fabricated from cobalt-chromium alloy [9], [16], [17]. The retained stem had no option of a titanium sleeve for the use of a new ceramic head.…”

A case of bone necrosis with pseudotumor following metal-on-metal total hip arthroplasty

A case of bone necrosis with a pseudotumor following metal-on-metal total hip arthroplasty is presented. The patient showed no abnormal magnetic resonance findings 2 years postoperatively, but serum metal ion levels were elevated. The patient developed hip pain 3.5 years postoperatively, and bone necrosis with a pseudotumor was found. The present patient emphasized the fact that tissue necrosis associated with failed metal-on-metal bearing hip might not be limited to soft tissues, but bone necrosis could occur.

“…3). Reactions may include osteolysis, bone necrosis, muscle necrosis, tendon necrosis with or without detachment, capsular necrosis with or without dehiscence, capsular thickening, cystic lesion(s), excessive fluid collection(s), ALVAL, and soft tissue masses [10,11,[33][34][35][36][37]. Many of these features are seen in variable amounts in cases of ALTR and it is not clear why some lesions show a predominance of one feature over the others.…”

Recognizing and adopting standardized terms for adverse local tissue reaction associated with tribocorrosion in total hip arthroplasty are essential for clear scientific discourse and clinical communication. Our goal was to develop terms that can be broadly applied to characterize the local tissue response to tribocorrosion debris, based on current evidence regarding the etiology of this failure mode and its consequences. The proposed standardized terms will improve the understanding and interpretation of analytical tests, advance diagnostic and treatment algorithms, and reduce confusion in research by maintaining consistent nomenclature.
