These defects arise from a variety of causes-high-energy trauma, blast injuries, bone infection, or oncological resection-and their management almost always demands a staged approach involving infection control, soft-tissue handling, and eventual restoration of skeletal continuity. A fundamental challenge throughout this process is keeping the affected limb mechanically stable between the initial operation and the definitive reconstructive procedure. External fixation has long served this role, since it stabilises the limb without introducing implants into potentially infected territory. However, prolonged reliance on external fixation is associated with several disadvantages: Patient discomfort, pin-tract infection, limited functional activity, and practical difficulties when soft-tissue reconstruction is subsequently needed.</p><p><strong>Patients and methods: </strong>A conceptual analysis of current stabilisation strategies for critical long-bone defects was performed, including external fixation and internal fixation methods. Particular attention was given to the biomechanical conditions present in large segmental defects, where a three-component system-bone, spacer, and fixation construct-determines overall stability.</p><p><strong>Results: </strong>Standard internal fixation methods are similarly constrained when large segmental defects are present. Placing permanent implants in an infected bed risks sustaining or reactivating infection, which is rarely an acceptable trade-off at the early stages of reconstruction. Stabilisation in the setting of a large segmental defect also operates under different mechanical conditions than a simple fracture. Here, the construct must manage not just two bone ends and a fixator, but a three-component system-bone, spacer, fixator-in which the spacer occupying the defect zone is an active mechanical participant. Stability depends on how all three elements interact, not on the fixator alone.</p><p><strong>Conclusion: </strong>In this conceptual paper, we introduce temporary internal stabilisation (TIS) as a distinct framework in the staged management of critical long-bone defects. Temporary internal stabilisation describes the use of internal constructs that provide mechanical stability and preserve limb alignment and length during the period between the first operation and the definitive reconstruction. We argue that this approach can meaningfully extend the options available in reconstructive orthopaedics and offers a fresh conceptual lens through which complex bone defects can be approached.</p>","PeriodicalId":21979,"journal":{"name":"Strategies in Trauma and Limb Reconstruction","volume":"20 3","pages":"167-172"},"PeriodicalIF":0.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13457378/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148713655","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}
