[Dislocation of the humerus--diagnosis and the Arlt method of reduction].

Authors present 248 shoulder dislocations included recurrent dislocations in a 3-year period. All of dislocations were of anterior type except 3 posterior dislocations and 1 inferior or luxatio erecta. They describe and recommend method of reduction without local or general anesthesia according to Arlt, which was used in 234 cases with effectivity of 96.6%. Posterior dislocation can have a very subtle signs and is generally initially missed in more than 50% cases. Two X-ray views in posterior dislocation are necessary to confirm diagnosis. Authors used in addition to anteroposterior transthoracic view with no posterior dislocation missed.
