The following is true about the elbow joint The elbow is made up of the humeroulnar, humeroradial and proximal radioulnar joints
The elbow flexors are stronger than the extensors The MCL is taut during distraction at 90 degrees of elbow flexion The joint capsule resists extension from neutral into hyperextension?
