Abstract
PURPOSE: No validated method currently exists to preoperatively estimate tibial nail length for tibial fractures. While various anthropometric measurements have been suggested, none seem to allow for both accuracy and practicality, complicating treatment. This study aimed to evaluate the use of patient body height in preoperatively predicting tibial nail length. METHODS: Patients with tibial fractures treated with intramedullary nail at a single level 1 trauma center were included. Patient body height and tibial nail size were used to develop a predictive equation. RESULTS: 220 patients were included and reviewed in this study. A logarithmic predictive equation was developed to accurately predict tibial nail length 82% of the time. CONCLUSIONS: Tibial nail length can be accurately predicted from patient body height. Compared to other anthropometric measurements, patient body height can be easily and consistently measured. Additionally, this study involved the largest sample size compared to other anthropometric studies predicting tibial nail length.
