The most common mechanism producing posterior dislocation of the radius and ulna compared to the humerus is the fall back on the arm with the elbow flexed and the forearm supinated.
The first goal of rehabilitation is to control the pain and joint function recovery through gradual mobilization of the elbow both in inflection/extension and pronation/supination without forgetting the joint recovery of the upstream and downstream joints of the same to avoid a deficit of movement and massage therapy for upper limb muscles.
Once you gained the full range of motion you can proceed to the second phase of the treatment protocol focused on the gradual strengthening of the muscles first with manual resistance then reinforced with rubber bands and weights of the biceps and triceps, prono-supinator.
It is important to recover the strength of the forearm and shoulder muscles, especially the muscles of the rotator cuff and epitrochlear and epicondylus muscles.
The most common mechanism that causes posterior dislocations of the radius and ulna on the humerus, is the fall back on arm with flexed elbow.
