Abstract
Various studies have been conducted on the preparation of hip and knee spacers for the local treatment of infections in terms of choosing the right antibiotic and dose and designing the components. [2, 3, 7]. In fact, in addition to releasing the drug to treat the infection, the spacer’s goal is to enable joint movement [8] and to support a partial load without further bone loss. The advantage of the two-stage technique is that the patient is not obliged to stay in bed for the period in which the infection is being treated and the shortening of his extremity is preserved [5]. The efficacy of the two-stage treatment using the spacer has given positive results in more than 90% of cases [3, 4] with an average follow-up of 36 months. In some cases the stems broke [6], Failure has not been directly related to the use of the spacer except in a small number of fatigue failure of the stem [2]. Even the process of wearing, tested in vitro with acetabular corpse cups, seem to indicate the hip spacer’s improved performance with a limited release of wear particles [1].
