摘要: A tripolar all ceramic joint is an emerging technology that reduces the risk of dislocation and subluxation in T.H.R. Muscular insufficiency, caricatural lower limbs discrepancies or neurological problems are classical causes for T.H.P. dislocations subluxations [10,11]. Instability may also be linked to 2 specific mechanisms, lever-out (with impingement) shear-out (without impingement).
