These alpacas each had a history of severe forelimb lameness for one week (n: 1), four weeks (n: 2) and for two-to-three months (n: 2). Two of the five alpacas were euthanized due to severe osteoarthritic changes that developed during the two-to-three months of scapulohumeral luxation. Three alpacas were treated with open reduction and internal stabilisation by placing tension band sutures between one 4,5 mm cortical screw anchored in the scapular neck and two 4,5 mm cortical screws anchored in the greater humeral tubercle, all of them provided with washers. Post-surgery a carpal flexion sling was applied to avoid postoperative weight-bearing. An exercise programme was started after removal of the carpal sling and continued for 12 weeks. In one of the three alpacas an additional non-displaced fracture of the acromion occurred two weeks after surgery. In conclusion, all three treated alpacas had good-to-excellent long-term outcomes and are still alive 123, 15 and 12 months after surgical repair of the scapulohumeral sub-/luxation. As four weeks, or even up to three months elapsed in four of these five alpacas until a definitive diagnosis was made, more education should be provided to alpaca owners that severely lame animals should be presented to a veterinarian with adequate diagnostic possibilities and expertise as soon as possible in order not to compromise treatment success.</p>","PeriodicalId":21544,"journal":{"name":"Schweizer Archiv fur Tierheilkunde","volume":"166 2","pages":"80-91"},"PeriodicalIF":0.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139651646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
