Nevertheless, several aspects warrant further discussion. Of particular note is the failure to stratify outcomes by exact time-to-treatment intervals, lack of long-term visual follow-up in a considerable number of patients, and heterogeneity in treatment modalities weaken the impact of outcome interpretation. Additionally, inadequate granularity of fracture characterization and absence of a uniform treatment protocol might confine the study's significance. We recommend that future studies incorporate subgroup analyses on a detailed basis according to intervention timing, CT-based fracture severity scores, and evidence-based treatment pathways to facilitate standardized management. Prospective, multicenter trials could also more effectively control for confounding variables like comorbidities and coagulopathies.
