This group includes Axial Spondyloarthritis, Ankylosing Spondylitis, Reactive Arthritis, Psoriatic Arthritis, and Enteropathic Spondyloarthritis, which is associated with inflammatory bowel disease. A key aspect of SpAs is the potential for significant overlap among these seronegative conditions in terms of their origin, pathological processes, clinical presentations, and therapeutic approaches, indicating they may not always represent entirely distinct entities. The document also includes a detailed illustration of a typical enthesis, the site where tendons or ligaments attach to bone, specifically depicting the Achilles tendon attachment to the calcaneus. This visual aid highlights the anatomical structures involved, including various layers of fibrocartilage and the retrocalcaneal bursa, which are relevant to understanding the inflammatory processes in enthesitis, a hallmark of spondyloarthritis. The provided diagrams, including a Venn diagram, further illustrate the complex relationships and overlaps between different types of spondyloarthropathies, such as Axial Spondyloarthritis and Peripheral Spondyloarthritis, and their subtypes like Psoriatic Arthritis (PsA), Reactive Arthritis (ReA), Inflammatory Bowel Disease-Spondyloarthritis (IBD-SpA), and Undifferentiated Peripheral SpA. This visualization helps to conceptualize how these conditions can manifest and interconnect in patients, underscoring the challenges in their diagnosis and management.",{"@graph":14,"@context":55},[15,34],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/healthcare/","Healthcare",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/spondyloarthropathies/26864/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/spondyloarthropathies/26864.png","ImageObject",300,407,{"name":42,"@type":43},"Theodore","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-09-19","2026-05-08",true,{"@type":52,"interactionType":53,"userInteractionCount":22},"InteractionCounter",{"@type":54},"ViewAction","https://schema.org",{"og:url":57,"og:type":58,"og:title":10,"og:site_name":45,"og:description":12},"https://docshare.wps.com/document/spondyloarthropathies/26864","article",{"robots":60,"canonical":57},"index,follow",{"doc_id":62,"site_id":7},26864,1778200129,{"code":4,"msg":65,"data":66},"success",[67,71,75,79,84,89,93,98,103,106,110],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":68,"show_sort_weight":69,"slug":70},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":72,"show_sort_weight":73,"slug":74},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":76,"show_sort_weight":77,"slug":78},"Exam",70,"exam",{"id":80,"doc_module":4,"doc_module_name":25,"category_name":81,"show_sort_weight":82,"slug":83},5,"Comic",60,"comic",{"id":85,"doc_module":4,"doc_module_name":25,"category_name":86,"show_sort_weight":87,"slug":88},6,"Technology",50,"technology",{"id":90,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":91,"slug":92},7,40,"healthcare",{"id":94,"doc_module":4,"doc_module_name":25,"category_name":95,"show_sort_weight":96,"slug":97},8,"Research & Report",30,"research-report",{"id":99,"doc_module":4,"doc_module_name":25,"category_name":100,"show_sort_weight":101,"slug":102},9,"Religion & Spirituality",20,"religion-spirituality",{"id":101,"doc_module":4,"doc_module_name":25,"category_name":104,"show_sort_weight":101,"slug":105},"World Cup","world-cup",{"id":107,"doc_module":4,"doc_module_name":25,"category_name":108,"show_sort_weight":107,"slug":109},10,"Lifestyle","lifestyle",{"id":111,"doc_module":4,"doc_module_name":25,"category_name":112,"show_sort_weight":80,"slug":113},19,"General","general",{"code":4,"msg":65,"data":115},{"doc_id":62,"user_id":116,"nickname":42,"user_avatar":117,"doc_module":4,"category_id":90,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":11,"file_id":118,"file_url":119,"file_type":120,"file_size":121,"view_count":22,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":122,"language":123,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":11,"faqs":11,"seo_title":124,"seo_description":12,"update_tm":63,"read_time":39},7971461740886,"https://ap-avatar.wpscdn.com/davatar_3d24733baf745e90a7e4bdd5f77d97b2","cbCaioUb1uScPYNS","https://ap.wps.com/l/cbCaioUb1uScPYNS","pdf",6584786,119,"English","Spondyloarthropathies | PDF"]
