Résultats cliniques et radiographiques à 2 ans des prothèses totales d'épaule à tige courte non cimentée Ascend Flex Tornier/Wright

Abstract : Introduction: the results of reverse total shoulder are now well known with many studies showing good results (reduction of pain and improvement of mobility). An alternative is the use of prostheses with short uncemented stems with metaphyseal support. The objective of this study is to observe the clinical and radiographic results of these prostheses at a 2 years follow-up. Material and methods: patients operated of a total reverse shoulder arthroplasty using an uncemented short stem Ascend Flex prosthesis (Tornier/Wright, Memphis,Tennessee, USA) at the University Hospital of Caen between 01/2017 and 04/2018 were retrospectively included in this study. The post-operative evaluation was performed at 3 months, 6 months, 1 year and 2 years, and included mobility, Constant score and Constant score based on age and sex, SSV, radiological evolution and occurrence of complications. Results: 34 patients were included, mean age 71.9 years (49-86). The clinical results at 2 years were a mean gain of 46° in EAA and 35° in ABD. No gain was found for rotational mobility. The functional scores for Constant, Constant based on age and sex and SSV were significantly increased at a 2 years follow-up by 41.23 points, 56.93 points and 56.85 points respectively. Radiological changes were observed at 2 years in 67.86% of patients, without affecting clinical results. Conclusions: in this study, the Ascend Flex short stem uncemented prosthesis is a prosthesis with good clinical results. The radiological results are also encouraging, but a long-term follow-up is needed to confirm them.
