In the article by Bruyn et al published in the August 2010 issue of Arthritis Care & Research (pp. 1079–1086), the legends for Figures 1 and 2 are incorrect. Figure 1 legend should read, “Long axis scan of axillary pouch showing anechoic structure corresponding to effusion as well as showing a spur of humeral head (arrowheads).” Figure 2 legend should read, “Short axis scan of posterior glenohumeral joint showing anechoic structure corresponding to effusion (H; arrowheads).”
In several articles published in 2009–2010, the affiliation information for one of the authors/contributors, Dr. Paul Emery, was incomplete. Dr. Emery's affiliation should have been listed as University of Leeds and NIHR Leeds Musculoskeletal Biomedical Research Unit, Leeds, UK. The article on which Dr. Emery was an author was as follows: Kavanaugh et al, Arthritis Rheum (Arthritis Care Res) November 2009 (pages 1592–1600). The article on which Dr. Emery was a contributor listed in the appendix was Dixon et al, Arthritis Care Res (Hoboken) June 2010 (pages 755–763).
