Repeated Ceramic Head Fracture after Ceramic-on-ceramic Total Hip Arthroplasty

Alumina ceramic-on-ceramic total hip arthroplasty is a widely-adopted option, especially for younger patients, due low wear, scratch resistance, the wettable characteristics of alumina ceramics, and because of the relatively low biological reactivites of ceramic wear particles. However, fracture remains a significant problem because ceramics are inherently brittle, and few reports have been issued on short head fractures. In the described case, a ceramic head fracture occurred only 8 months after replacing the original head and with a new 28 mm head and liner. Both of these incidents may have been caused by head-to-liner impingement due to excessive anteversion of the metal shell. During the second revision surgery, this situation was managed successfully using a conventional elevated-polyethylene liner and a CoCr metal head, while retaining all metal implants.

Due to the increasing number of total hip arthroplasties performed during the last three decades and the limited long-term survival, mainly because of wear, the number of revisions has increased during the last two years. If the implant itself is still considered to be stable, only head and inlay exchange is necessary. This requires comprehensive knowledge of the characteristics of the articulating materials by the surgeon as the wrong choice of wear couple can lead to early failure for a second time. The aim of this paper is to present considerations and strategies for head and inlay exchange in case of failure, either due to wear of the articulation material or of other indications for revision hip arthroplasty.

“…Liquid lubricant to serve in conjunction with ceramics is not available, so attempts were made with solid lubricants. Zirconia, SiC, SiN, Al2O3 was used as bearing materials (Skinner 1999 andShi et al 2003). Ceramics are the most suitable materials for artificial hip and knee joints due to their very low wear rate (Bal et al 2007 andSkinner 1999) Composite bearings are in existence right from the evolution of composite materials.…”

In the past few years, the need for low-cost, high-performance materials is increasing. Design engineers and researchers are replacing the metals and alloys with advanced materials. Journal bearings are integral parts of machines, engines running to serve the purpose. They play a significant vital role in the performance, efficiency, minimizing the cost of operation, enhancing the durability and reliability of the system. Materials used for these moving elements have undergone tremendous change since the invention of Tin Babbitt. In this paper, a critical review of Journal bearing materials, right from the old-age Babbitt to advanced materials in use till date is presented. Metallurgical aspects and mechanical behavior of successful, widely used bearing materials along with their micro and nanocomposite alternatives are discussed. Tin Babbitt is an ideal material for journal bearing applications. So, it is taken as reference for comparing the quality of other bearing materials.
