Elbow deformity

The elbow joint is one of the most stable joints in the human body.The maintenance of its stability depends on the integrity of the joint structure.Its maximum flexion and extension can reach 160 °, the pronation can reach 85 °, and the supination is about 80 °. The long axis of the humerus forms a valgus angle of 6 ° and an internal rotation angle of 5 ° to 7 ° with the intercondylar axis. The elbow flexion and extension axis is located in front of the humerus midline and forms a 40 ° angle with the humerus shaft. Elbow joint dislocation, fracture and other reasons can cause elbow deformity.
