In 2006 over 55 000 primary total hip replacements were implanted in the UK. A crucial aspect of follow-up for these patients is the assessment of the postoperative radiograph. Information gained from the initial radiograph includes assessment of the quality of implantation and hence the likelihood of long term success. Follow-up radiographs can be assessed for signs of component failure. Orthopaedic surgeons, radiologists, junior surgical trainees, general medical practitioners, and advanced nurse/extended scope practitioners may all be required to interpret these radiographs during clinical practice. The authors feel that certainly during orthopaedic surgical training, not enough time is allocated to formal training on the systematic assessment of such radiographs. This review aims to provide the reader with a systematic approach to analysing the initial postoperative total hip arthroplasty radiograph, and subsequent follow-up films. Basics of patient positioning for obtaining radiographs, types of prosthesis encountered, and terminology used are covered. Assessment of initial radiographs focuses on assessing leg length, acetabular and femoral positioning, and cement mantle adequacy. Follow-up radiographs are assessed for signs of component failure. A review of the literature provides evidence for the assessment and importance of adequacy of component positioning, and good cementing technique. Normal and abnormal follow-up radiographic features are outlined to allow assessment of loosening or impending failure of a prosthesis.
