Articulating components should minimise the generation of wear particles in order to optimize long-term survival of the prosthesis.A good understanding of tribological properties helps the orthopaedic surgeon to choose the most suitable bearing for each individual patient.Conventional and highly cross-linked polyethylene articulating either with metal or ceramic, ceramic-on-ceramic and metal-on-metal are the most commonly used bearing combinations.All combinations of bearing surface have their advantages and disadvantages. An appraisal of the individual patient’s objectives should be part of the assessment of the best bearing surface.Cite this article: Rieker CB.

“…In July 2014, a 48-year-old female patient referred to hospi- More than one million MoM arthroplasties were implanted worldwide till now [2]. Recent reports have recommended the discontinuance of MoM arthroplasties due to multiple side effects and complications [6]. Cobalt and crom ion levels increases three to five times in MoM arthroplasties [2,6].…”

“…Patients can develop local reactions to the metal ions leading pain, aseptic loosening, periprosthetic osteolysis and metal hypersensitivity [3,7]. A large number of adverse local tissue reactions associated with the metal debris generated from the bearing area or tapered junctions have been demonstrated [2,3,6]. Pseudotumors, aseptic lymphocyte-dominated vasculitis associated lesions (ALVAL) and squeaking are the miscellaneous concerns [2,3,6].…”

We report a very rare and extraordinary complication, metal head fatique fracture at the site of the socket tip deep border and coin like metal corpora libera in two cases with metal on metal total hip prosthesis. Catastrophic wear at the site of the deep border of the collum socket and coin like loose body originating from the crom-cobalt head resulted with metallosis, osteolysis and failure. The outcomes of the revision operations were satisfactory and the patients returned to their daily activity without discomfort in their hip. Headwear is a well-known result of the metal on metal articulation and may present with instability, metallosis, pain and mechanical symptoms. These incidents might be important to investigate for tribological performance of hip implants in biotribology science. We believe-3 sized metal head usage might be the reason of this catastrophic complication their usage should be avoided in metal on metal artroplasties.

The main reason for total hip arthroplasty (THA) revision is the wear-related aseptic loosening. Younger and active patients after total joint replacement create high demands, in particular, on the bearings. The progress, especially for alumina ceramic-on-ceramic bearings and mixed ceramics have solved many problems of the past and lead to good in vitro results. Modern ceramics (alumina or mixed ceramics containing alumina) are extremely hard, scratch-resistant, biocompatible, offer a low coefficient of friction, superior lubrication and have the lowest wear rates in comparison to all other bearings in THA. The disadvantage of ceramic is the risk of material failure, i.e., of ceramic fracture. The new generation of mixed ceramics (delta ceramic), has reduced the risk of head fractures to 0.03-0.05 %, but the risk for liner fractures remains unchanged at about 0.02 %. Assuming a non-impinging component implantation, ceramic-on-ceramic bearings have substantial advantages over all other bearings in THA. Due to the superior hardness, ceramic bearings produce less third body wear and are virtually impervious to damage from instruments during the implantation process. A specific complication for ceramic-on-ceramic bearings is "squeaking". The high rate of reported squeaking (0.45 to 10.7 %) highlights the importance of precise implant positioning and the stem and patient selection. With precise implant positioning this problem is rare with many implant designs and without clinical relevance. The improved tribology and the presumable resulting implant longevity make ceramic-on-ceramic the bearing of choice for young and active patients.

Metal-on-Metal Bearing: Is this the End of the Line? We Do Not Think So

Abstract: Adequate selection of MoM articulations ensures their safe use. These articulations are sensitive to orientation. Fifteen years of safe experience with 28- and 32-mm bearings of forged alloy and high-carbide content is the main reason for retaining them in primary and revision THA.
