In spite of numerous prophylactic measures infections after primary total hip arthroplasty (THA) still occur in 0.5 - 1.4 % of the cases [4]. Generally, joint infections are categorised in early (within 6 weeks after surgery) and late infections (> 6 weeks) [15]. Efforts for infection management in early cases with prosthesis preservation include debridement, necrosectomy, pulsatile lavage, insertion of antibi-otic-loaded device (PMMA-beads, collagen sponges) or flush-suction drain [15]. Should these methods be unsuccessful, a one-stage procedure is usually carried out [1, 15]. Hereby, the infected prosthesis is removed, debridement and jet lavage of the infected area are performed and a new endoprosthesis is reimplanted at the same time. In most of these cases the infection management consists of systemic antibiosis and anti biotic-loaded bone cement for fixation of the prosthe sis. The patient is not endangered by the risks of add ditional surgeries, and the success rates are reportedly between 80-85 % [15]. However, in case of a surgical revision with prosthesis retention, one of the major problems migh be wound healing complications with a persisten draining sinus despite revision. In multiple surgica
