A retrospective, monocentric study will be performed. Patients who underwent surgical treatment after suffering a Monteggia injury or a Monteggia like lesion between 2012 and 2018 will be included. Fractures will classified after Bado and Jupiter, according to the fracture location of the proximal ulna, as well as regarding the potential accompanying ligamentary injury.~In a follow-up examination validated patient-reported outcome measures (Disabilities of Arm, Shoulder and Hand Score [DASH], MEPS [Mayo Elbow Performance Score], Oxford Elbow Score [OES], Pain, Subjective Elbow Score) and functionality (range of motion [ROM], posterolateral instability, strength, valgus-/varus-stress) will be evaluated. In addition, treatment strategy and complications will be analysed.
Patients who had suffered a Monteggia fracture (lesion of the elbow) will be assessed regarding clinical and functional outcome (PROM) after treatment with osteosynthesis.
