An innovative alternative to this procedure offers a more minimally invasive nail stabilization. The purpose of this biomechanical study was to clarify whether this method was biomechanically comparable to the established method. First, the stability (range of motion, diastasis) and rotational stiffness of the native upper ankle were evaluated in eight pairs of native geriatric specimens. Subsequently, an unstable ankle fracture was created and fixed with a locking plate or a nail in a pairwise manner. The ankles showed significantly less stability and rotational stiffness properties after nail and plate fixations than the corresponding native ankles ( p < 0.001 for all parameters). When comparing the two methods, both showed no differences in their range of motion ( p = 0.694) and diastasis ( p = 0.166). The nail also presented significantly greater rotational stiffness compared to the plate ( p = 0.001). However, both fixations remained behind the native stability and rotational stiffness. Due to the comparable biomechanical properties of the nail and plate fixations, an early weight-bearing following nail fixation should be assessed on a case-by-case basis considering the severity of fractures. 4950 https://doi.org/10.3390/jcm12020698$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:27-dbt-20230203-185049-003$xR$3Volltext$534 4961 https://www.db-thueringen.de/receive/dbt_mods_00055606 5051 610 5550 biomechanical 5550 fibular nail 5550 geriatric fracture 5550 geriatric trauma 5550 open reduction and internal fixation 5550 osteosynthesis 5550 syndesmosis 5550 syndesmotic screw 5550 trauma surgery 5550 upper ankle joint
