Over the years, fixator design and biomechanical knowledge have led to different solutions and techniques, and bone lengthening and its better understanding come together with the development of external fixators and the application of the biological principle of distraction osteogenesis. The authors conducted a literature review about using external fixators and lengthening systems in pediatric upper limbs. Despite the applications of external fixators in upper limbs remaining much more limited than those of the lower limbs, there are indications of traumatic, congenital, tumor, and infectious etiologies. However, despite the spread of new systems of plate and screws and intramedullary lengthening nails, the problems about when to use external fixation remain unsolved. Another debated point is about using monolateral or circular frames for humeral lengthening and the correction of forearm deformities in multiple hereditary exostoses disease (MHE) or radial longitudinal deficiency sequelae. Monoaxial fixators retain a prominent role for skeletal lengthening in all the districts examined, although their role could be outclassed by the motorized intramedullary nails, especially for humeral lengthening. Hexapod systems are likely to represent the future for the correction of multiplanar forearm deformities; however, multicenter studies on larger series will be necessary to better validate their applications and advantages.</p>","PeriodicalId":56060,"journal":{"name":"Journal of Childrens Orthopaedics","volume":" ","pages":"139-150"},"PeriodicalIF":1.3,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11915237/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adoption of advanced methods like whole-body magnetic resonance imaging and computed tomography-like magnetic resonance imaging sequences has improved diagnostic accuracy, minimized radiation exposure, and expanded the capabilities of noninvasive imaging. Emerging technologies, including photon-counting detector computed tomography and deep learning-based reconstructions, are transforming clinical practices by balancing precision and safety. Artificial intelligence applications are reshaping diagnostic approaches, automating complex assessments, and improving efficiency, although challenges such as external validation and limited scope persist. Functional imaging advancements, such as diffusion-weighted imaging and positron emission tomography-magnetic resonance imaging integration, are enhancing disease characterization and treatment planning.
