Predicting mechanical complications in proximal femoral nailing for elderly patients: a radiological scoring system based on a single-centre retrospective cohort with 586 cases

TSS may aid in predicting and mitigating mechanical complications while potentially guiding surgical applications in PFN, but further prospective multicentre validation is required. While certain parameters of TSS could be considered intraoperatively, its full implementation may be more practical for postoperative risk assessment.
