Abstract

Purpose

Supratrochlear foramina (STF) are occasionally encountered in both clinical and anthropological contexts. However, their biomechanical impact on fracture susceptibility in the distal humerus remains poorly understood. This study aimed to evaluate whether the presence of a single STF affects the fracture load of distal HumerusHumerus models under axial loading.

Methods

Standardized foam bone models, simulating the distal humerus, were divided into two groups: (1) models with a single STF and (2) control models without STF. Axial compression tests were performed using a universal testing machine, and fracture loads and speciments stiffness were compared using independent t-tests and Mann-Whitney tests.

Results

The mean ± SD peak fracture loads were similar with 1160 ± 100 N and 1110 ± 165 N (P = 0.829) for the test and control groups, respectively. The mean fracture loads trended slightly different with 1050 ± 120 N and 960 ± 150 N for the test and control group, with no statistically significant difference (P = 0.060). Both groups displayed similar incomplete transverse fracture patterns and load-displacement behaviors, indicating comparable mechanical responses prior to fracture.

Conclusion

The presence of a single STF does not significantly compromise the fracture resistance of distal humerus models under axial loading. These findings provide preliminary biomechanical evidence that STF may be clinically tolerable, though further studies are needed in cadaveric and dynamic loading conditions to confirm these results.

期刊介绍： Morphologie est une revue universitaire avec une ouverture médicale qui sa adresse aux enseignants, aux étudiants, aux chercheurs et aux cliniciens en anatomie et en morphologie. Vous y trouverez les développements les plus actuels de votre spécialité, en France comme a international. Le objectif de Morphologie est d?offrir des lectures privilégiées sous forme de revues générales, d?articles originaux, de mises au point didactiques et de revues de la littérature, qui permettront notamment aux enseignants de optimiser leurs cours et aux spécialistes d?enrichir leurs connaissances.
