The anatomic-and-clinical substantiation of external fixation variants for fractures of the humerus in view of the peculiarities of its vascularization

The location of nutrient foramina of the bones prepared regarding the arrangement of nutrient arteries has been studied to determine the safest zones for fixator application to the humerus. The lateral epicondyle, anatomical neck and the greater tubercle area have been found as the most vascularized zones of the humerus. Canalis nutricius localization has been revealed to be significantly variable, that is of great importance for the application of external fixators in case of humeral fractures.
