A 66 year old male who sustained a femoral neck fracture treated with uncemented THR. Postoperatively he complained of unspecific pain with only slightly elevated infection markers. A) 3 years later loosening of the acetabular component was diagnosed with marked osseous defect periacetabular and signs of osteolysis around the proximal part of the stem. B) One stage exchange with uncemented components. The defects were filled with antibiotic impregnated bone Osteomycin V TM. Sonification of explanted material revealed growth of 2 strains of S.epidermidis (MSSE) and Propionibact. sp. Hospital stay was one week, with Cefuroxim intravenously, followed by 6 weeks Amoxicillin/Clavulanic acid + Rifampicin orally. C) 6 months postop: The patient is painfree with no sign of infection and unlimited mobility. There is partial remodelling of the allograft material with no sign of loosening of implants.
