“…Traina et al [21] suggest that in the absence of major damage marks, the taper might be safe for re-use with a new ceramic head. This study shows that ceramic heads might still fail early due to conditions preventing the optimal contact situation at the taper interface [27] and that visual inspection is not sufficient to identify such conditions. All ceramic heads are subject to proof tests after manufacturing to eliminate premature failure due to material inhomogeneity or defects.…”

“…Whilst alumina remains a popular material for implantation, newer technology has involved strengthening the ceramic matrix with a second material such as the yttria stabilised zirconia toughened alumina (ZTA) complex in an effort to reduce the matrix grain size and therefore reduce crack propagation. This compound demonstrates increased toughness and bending strength compared to alumina alone but long-term studies are not yet available (30).…”

The optimum choice of bearing surfaces in total hip arthroplasty, particularly in the younger and more active patient, remains controversial. Despite several studies demonstrating good long-term results for the metal-on-polyethylene articulation, there has been a recent vogue towards the utilisation of hard-on-hard bearings for younger patients due, in part, to concerns regarding polyethylene induced osteolysis. However, well-documented complications concerning metal-on-metal bearings and the risk of fracture in ceramic-on-ceramic bearings have raised concerns regarding the principle of the hard-on-hard bearing in the active patient. With recent technological advancements in the manufacture of both polyethylene and alumina ceramics, the in vitro properties of each material with regards to strength and toughness have been significantly improved. In addition, ceramic femoral heads have consistently been shown to produce less in vivo polyethylene wear than similar sized metal heads. This paper aims to critically review the biomechanical, in vivo and clinical studies related to the use of the ceramic on polyethylene bearing, and highlights its potential use as the preferred bearing for a young adult hip replacement.
