[The post-traumatic frozen shoulder]

The post-traumatic frozen shoulder is a sickness which develops relatively frequently following even small injuries of the shoulder joint. The particular anatomic conditions of this joint are the cause of its frequent lesions. After an injury typical pathological changes in function are observed. Most common injuries are distorsions, contusions, luxations and especially in increasing age the subcapital fractures of the humerus. Other injuries as there are rupture of the acromio-clavicular joint, fractures of the clavicle or scapula may also cause a frozen shoulder. The clinical examination is most important as it is the basis of the therapy. The current procedure consists of intensive physical therapy. If this treatment is not successful other ways must be discussed, e.g. mobilisation under anaesthesia. Operative treatment has a very strict indication. Medico-legal points of view of the frozen shoulder are difficult but a connection between injury and degenerative changes ought not to be denied in clear cases.
