BACKGROUND: The optimal treatment for @entity6342 remains under debate. In this article, we report the mid-term results of @entity1 who underwent the less-invasive implantation of a polyaxial locking plate for displaced @entity6342 . METHODS: This study included @entity1 who were treated with a polyaxial locking plate via an anterolateral deltoid split approach from May 2008 to December 2011. We evaluated outcome parameters after a minimum follow-up period of 2.5  years (median 4.5  years, follow-up rate 62  %) including the age- and gender-dependent Constant score, the activities of daily living score, and the visual analog scale for both @entity158 and subjective shoulder function. RESULTS: Of the 140 @entity1 who underwent surgery, 114 were included in the follow-up and 71 completed the questionnaire. Fifteen @entity1 (21  %) exhibited 2-fragment @entity174 , and 56 @entity1 (79  %) exhibited 3- and 4-part @entity174 . The Constant score improved significantly (4.5  years: 70        21, p   <   0.001) between the first two follow-ups (6  weeks: 35        14, 6  months: 56        18, p   <   0.001), and also between 6  months and 4.5  years post-surgery. At the final follow-up, the activities of daily living score had not reached pre- @entity174 levels (before trauma: 27        5, 4.5  years: 20        8, p   <   0.001). A multivariate analysis showed that age has a more significant influence on the final outcome than @entity174 morphology or gender. CONCLUSION: Although the less-invasive surgical procedure is a feasible treatment option in @entity6342 with acceptable complications and considerable improvement during the first six months, a lengthy recovery time is required. The majority of our @entity1 did not become @entity158 -free or reach pre- @entity174 activity levels.
