Fixed angled locking screw plates are the mainstay of fixation. The A.L.P.S. Proximal Humerus Plating System is a new implant that has smooth locking pegs in the place of humeral head screws to help reduce glenoid damage in the event of cut-out and is designed to sit low on the humerus in order to reduce the risk of subacromial impingement.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Retrospective analysis of 15 consecutive patients who sustained closed displaced 3-part or 4-part fractures and had fixation surgery using the A.L.P.S. plate. Outcome measures were the time to radiographic and clinical union, Oxford Shoulder Score, quick DASH score and complications.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Average follow-up was 31.9 weeks. Union was achieved in 100% of patients with a mean time to union of 15.1 weeks. In terms of function, mean OSS was 33.6 and mean quick DASH was 32.5. There were no instances of AVN.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Our preliminary results of 15 patients followed up for a mean of 31.9 weeks show equitable union rates and time to union as well as functional scores compared to other available plating systems. This is the first study to report on this implant to date.<\/jats:p>\n <\/jats:sec>","DOI":"10.2174\/1874325001812010053","type":"journal-article","created":{"date-parts":[[2018,3,6]],"date-time":"2018-03-06T10:06:08Z","timestamp":1520330768000},"page":"53-58","update-policy":"https:\/\/doi.org\/10.2174\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Early Results of the A.L.P.S.
