High prevalence of radiographic CAM-type FAI among these skilled capoeira players was found. In these subjects, a negative clinical correlation for an increased α-angle was also detected. Additional caution should be exercised whenever subjects with past or present hip pain engage in capoeira.
We present a retrospective study of 107 cases of thumb carpometacarpl joint arthrodesis. The aim of our study was to analyse our population and to compare the outcomes of patients who obtained bone union with the patients who did not. There were no statistical differences in most of the clinical outcomes (DASH score, visual analogue scale, Kapandji test, grip, and key pinch) between the two groups of patients; there were fewer cases of scaphotrapeziotrapezoid arthritis in the group that did not obtain bone union. We conclude that the bone union is not necessary for a good outcome. Level IV of evidence.
The purpose of this study was to assess the long-term clinical results and morphological changes after tendon ball arthroplasty for advanced Kienböck's disease. Twenty-six patients were reviewed, with a mean follow-up interval of 125 months (range 50-226). At follow-up, mean score on the Disabilities of the Arm, Shoulder, and Hand questionnaire was 7.7 and mean visual analogue scale score for pain was 1. Mean carpal height ratio was significantly reduced with respect to the pre-operative value. On magnetic resonance imaging scans, cartilage damage, synovitis, and erosive or oedematous changes in the bones were detected in most patients. Calcification in the defect filled by the tendon ball was seen in all patients. Narrowing of the radioscaphoid joint and the presence of intercarpal synovitis were negatively associated with clinical outcome. Tendon ball arthroplasty in advanced Kienböck's disease results in long-term satisfactory clinical outcomes, despite widespread changes in the bones and joints within the wrist.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
