Injuries to the deltoid ligament are less common than lateral ankle sprains but can lead to chronic instability and dysfunction if not properly diagnosed and managed. Accurate diagnosis of deltoid ligament injuries is essential for appropriate treatment planning and optimizing patient outcomes. While magnetic resonance imaging (MRI) is considered the gold standard for ligament assessment, diagnostic musculoskeletal (MSK) ultrasound offers a portable, real-time, and cost-effective alternative that is gaining traction in rehabilitation and sports medicine settings. This article reviews the utility of MSK ultrasound in evaluating the deltoid ligament, including its anatomy, common injury patterns, sonographic techniques, and clinical implications for rehabilitation professionals. By integrating MSK ultrasound into clinical practice, providers can improve the accuracy of diagnosis, monitor healing progression, and guide rehabilitation strategies for optimal patient outcomes.</p>","PeriodicalId":47892,"journal":{"name":"International Journal of Sports Physical Therapy","volume":"20 4","pages":"641-647"},"PeriodicalIF":1.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11964700/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143781670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
