Abstract

Metallosis is a well-defined complication that may occur after artroplasties. Metallic biomaterials are used for disfunctional bone and joint tissues for a long time. Type of metal, its physical and chemical characteristics affect to tissue adaptation. These are the most convenient materials for skeleton-muscle system surgeries and used often. Metallosis is a result corrosion that occurs at joint because of protheses. In this text, three cases which are found metallosis between the years of 2016-2017 are discussed and presented in literature accompaniment.

Introduction

Stainless steels that are first inurement, cobalt-chromium alloys, titanium alloys, alumina, zirconia and some porous ceramics, silicon, polyethylene, polyurethane, polypropylene and polymethyl methacrylate are often used for orthopedic surgeries [1]. The stability of metallic biomaterials is higher than others, however these materials may react with body liquids differently and cause metallosis. Metallosis is an infiltration with metallic debris surrounding tissue of prothese, after then conversion to granulation tissue with macrophages and giant cells [2]. Metallosis is a well-defined complication that may occur after artroplasties [3]. Typical symptoms are presented as pain, swelling and deformity. High activity level of person is a factor that decreases the life of prostheses and this factor leads up to metallosis [4]. Metallosis has to be diagnosed early and its treatment has to start to prevent the bone destruction. Revision surgery is essential for the treatment.

Case Presentation

Case 1

A woman 81-year-old who had a bilateral total knee artroplasty 17 years ago, consulted our clinic with complaints as pain on both of knees and incapability to walk. The total revision arthroplasty was applied to the left knee. Intense metallosis tissues and pseudomembran were seen. Pseudomembran was excised expansively and metallosis tissues were debrided. These were sent to pathology laboratory. In macroscopic examination, one surface of operation material is dark green irregular-looking, relatively smooth; another surface of it relatively paries, that between 0.5-1 cm thickness, with adipose tissue. When these surfaces were compounded, the material reached 12.5 x 10 x 4 cm measures. Samples were taken from green and villous parts of the material (Figure 1). In microscopic examination, polyetylene-like-particle were in sight in the excision material under the polarize light (Figure 2A and 2B). Metallosis diagnosis was given the case with present indication.
