“…The mechanism of elbow dislocation has been the subject of debate 2,6 , and different theories being proposed. It is essential to understand the factors that could lead to elbow injuries and instability and to establish measures of diagnosis and treatment 8 or prevention in different cases, like pediatric sports in particular 11 .…”

“…Elbow dislocations can range from simple to complex. Complex acute elbow dislocations can involve fractures, are accompanied by patient apprehension and pain 2 and may require surgical intervention 4 . Simple elbow dislocations have been described as those which were accompanied by fractures apart from avulsions 1 or 2 mm in diameter 5,6 , or those restrained to injuries in the soft tissues 5,7 .…”

This paper aims to explore various methodologies employed in investigating elbow dislocation, focusing on its causes and effects.Reconstructing the fall is one of the most challenging problems in bio-mechanics. The dislocation is evaluated about different loads and moments applied to the radius-ulna when the arm is flexed and positioned in either supination or pronation. The experimental study of over 70 baboons and 21 human cadaver arms supported our hypothesis for the observed early stages of dislocation. The experiments reveal that the retention of sufficient bony and soft tissue allows for achieving elbow stability through various repair mechanisms. The results of multiple experiments involving flexion, pronation, and supination consistently reveal that the ligaments remain undamaged. Even though it is challenging experimentally, achieving a perfect dislocation typically involves the posterior displacement of the radial head after the ligaments have incurred partial tears. Notably, experimental evidence suggests that the radial head can serve as a stabilizing factor in cases of elbow dislocation, often leading to bony failure, including fractures of the coronoid process and/or anterior radial head.
