Jupiter and Mehne Classification

Overview[1][2]
The injuries of the ball-and-socket shoulder joint considered as the Distal humerus fracture. It is more common among the elderly population following a low energy trauma such as falling. Meanwhile, A few people experience the axillary nerve damage such as reduced sensation around the middle deltoid and/or axillary artery involvement.
