Cup Positioning In Total Hip Arthroplasty / Th. Scheerlinck in Acta Orthopaedica Belgica, Vol 80/3 (Septembre 2014)
[article]
Titre : Cup Positioning In Total Hip Arthroplasty Type de document : texte imprimé Auteurs : Th. Scheerlinck, Auteur Année de publication : 2014 Article en page(s) : p.336-347 Langues : Anglais (eng) Mots-clés : hip arthroplasty cup orientation acetabular component biomechanics Résumé : The “optimal” positioning of the cup in total hip arthroplasty can improve hip function and reduce wear, impingement and dislocation. The cup position is described as the spatial relation between the hip rotation centre and the pelvis and, as the cup orientation around the rotation centre. The first parameter affects hip balance and, if not managed properly, might result in poor function and leg length discrepancy. The second parameter is often “silent”, unless impingement or dislocation occurs. However, inappropriate cup orientation can accelerate wear and cause early failure. As such, it is mandatory to get both right, taking into account multiple parameters : the stem position, the approach, the bearing surface, the cup coverage and the pelvic orientation during loading. In most cases a “standard” cup position is adequate. However, specific anatomic features might require an individualized approach. This paper aims at reviewing the parameters that impact on the optimal cup position. This should allow for more judicious choices in those particular cases.

[article]
Titre : Dynamic trial fitting of the cup in press-fit total hip arthroplasty, a feasibility study Type de document : texte imprimé Auteurs : Daniël Hoornenborg ; Justin Van Loon ; Sheryl De Waard ; Inger Sierevelt ; Kim T.M. Opdam ; Gino M.M.J. Kerkhoffs ; Daniël Haverkamp Année de publication : 2021 Article en page(s) : p. 327-331 Note générale : https://doi.org/10.52628/87.2.18 Langues : Anglais (eng) Mots-clés : press-fit trial fitting acetabular component total hip arthroplasty Résumé : Trial fitting of the cup during total hip arthroplasty (THA) is done by trial cups, which do not resemble the real press-fit obtained by the definitive implant. Our goal is to judge feasibility of the X-pander® in clinical practice ; a device developed to mimic the real press-fit obtained by the definitive cup, to ensure satisfactory press-fit.
In this feasibility study 45 experienced orthopaedic surgeons from 7 European countries filled in a structured survey after 78 primary THA and 31 revision surgeries, using the X-pander instead of traditional trial cups. Primary outcomes were decision change concerning cup size or further reaming and increased confidence regarding cup insertion and size. Additionally, potential association between the primary outcomes and procedure (primary or revi- sion), bone quality and experience of the surgeon were evaluated.
In 33.3% of the primary and 32.2% of the revision cases the X-pander measurement changed the deci- sion and further reaming or change of cup size was decided. In 61.5% and 58.1% of respectively the primary and revision THAs the X-pander was judged to give fairly to much more reliable information than traditional trial cups. The X-pander could lead to less additional screw fixation, as stated in 37.2% of the primary and 25.8% of the revision cases and to better cup insertion in respectively 50.0% and 51.6%.
This study validates that the X-pander may be a suitable option for accurate sizing and assessment of the reamed acetabulum and could replace traditional trial cups in THA.Permalink : ./index.php?lvl=notice_display&id=96668
