Elbow dislocation

Dislocation of the elbow joint accounts for half of the total dislocations of the four major joints throughout the body. The lower end of the humerus, which forms the elbow joint, is wide inside and outside, and thin before and after. The side is protected by strong ligaments, and the front and back of the joint capsule are quite weak. The movement of the elbow joint is mainly flexion and extension. The ulna coronoid process is smaller than the olecranon process. Therefore, the ability to resist backward movement of the ulna is worse than the ability to resist forward movement. Therefore, posterior dislocation of the humeral joint is far more common than dislocation in other directions. Fresh dislocation will not leave obvious dysfunction after early correct diagnosis and proper treatment. Failure to get timely and correct treatment early can lead to severe dysfunction in the later stages. At this time, no matter what kind of careful treatment, it is difficult to restore normal function, but only to improve the function. It often occurs in adolescents, and it often happens in adults and children. Due to the more complex types of elbow dislocations, other structural injuries of the elbow are often combined, and care should be taken to prevent misdiagnosis during diagnosis and treatment.
