Accurate and reproducible radiological assessment of shoulder replacement prostheses over time is important for identifying failure or to provide reassurance. A number of clearly defined radiological parameters have been described to help standardise the radiological assessment of prostheses. To our knowledge, this is the first study conducted to test the reproducibility and reliability of these measurements. The aim of this work was to test intraobserver reproducibility and interobserver reliability in the measurement of humeral component orientation (HCO), humeral head offset (HHO), humeral head size (HHS), humeral head height (HHH), and acromiohumeral distance (AHD.)Background
Aim
Medical complications and death are rare events following elective orthopaedic surgery. Diagnostic and operative codes are routinely collected on every patient admitted to English NHS hospitals. This is the first study investigating rates of these events following total joint replacement (TJR) on a national scale. All patients (585177 patients) who underwent TJR (hip arthroplasty [THR], knee arthroplasty [TKR], or hip resurfacing) between 2005 and 2010 were identified. Patients were subdivided based on Charlson co-morbidity score. Data was extracted on 30-day complication rates for myocardial infarction (MI), cerebrovascular event (CVA), chest infection (LRTI), renal failure (RF), pulmonary embolus (PE) and inpatient 90-day mortality (MR).Background
