    Sammanfattning : 144 consecutive hip revisions performed with morselized allograft bone and cement were followed up to 5 years after surgery. In 49 hips patient outcome was evaluated with the Nottingham Health Profile (NHP) questionnaire and Charnley hip scores in 47 hips prosthetic fixation was evaluated with radiostereometry (RSA)and in all 144 hips risks and complications were recorded using a prspective protocol.
