Whilst this may seem like three degrees of freedom, circumduction is actually a combination of flexion/extension and abduction/adduction and therefore\u0026nbsp;saddle joints only allow two degrees of freedom of movement. \u0026nbsp;\u003c/p\u003e\u003cp\u003e\u0026nbsp;\u003c/p\u003e","id":885,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/887","nextQuestionPath":null,"relatedArticles":[{"id":42716,"title":"Saddle joint","link":"/articles/saddle-joint?lang=us"},{"id":42685,"title":"Joints","link":"/articles/joints-1?lang=us"}],"alsoUsedIn":[{"id":23,"kind":"Course","title":"Medical Imaging Anatomy Course - Melbourne - page 23","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-course-melbourne-2017/pages/23"},{"id":23,"kind":"Course","title":"Medical Imaging Anatomy Course - Melbourne - page 23","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-course-melbourne-2018/pages/23"},{"id":23,"kind":"Course","title":"Medical Imaging Anatomy Course - Melbourne - page 23","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-course-melbourne-2019/pages/23"},{"id":23,"kind":"Course","title":"Medical Imaging Anatomy Webinars - page 23","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-webinar-2022/pages/23"},{"id":23,"kind":"Course","title":"Medical Imaging Anatomy Course - page 23","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-course-online/pages/23"},{"id":397,"kind":"Course","title":"Medical Imaging Anatomy Course - Melbourne - page 397","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-course-melbourne-2020/pages/397"},{"id":397,"kind":"Course","title":"Medical Imaging Anatomy Course - Melbourne - page 397","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-course-melbourne-2019/pages/397"},{"id":397,"kind":"Course","title":"Medical Imaging Anatomy Webinars - page 397","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-webinar-2022/pages/397"},{"id":397,"kind":"Course","title":"Medical Imaging Anatomy Course - page 397","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-course-online/pages/397"},{"id":397,"kind":"Course","title":"Medical Imaging Anatomy Webinar Series - page 397","link":"https://radiopaedia.org/courses/medical-imaging-anatomy-webinar-series/pages/397"}],"stem":"\u003cp\u003eWhich of the following\u0026nbsp;\u003cstrong\u003eIS FALSE\u003c/strong\u003e\u0026nbsp;regarding saddle joints?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/885"}],"attemptsPercentages":[{"alternativeId":"4449","percentage":23},{"alternativeId":"4452","percentage":12},{"alternativeId":"4451","percentage":7},{"alternativeId":"4453","percentage":53},{"alternativeId":"4450","percentage":5}],"promptToLogin":false,"questionManager":false,"articleId":"synovial-joints"}
