[Comparative evaluation of the methods of treatment of dislocations of the clavicle].

An analysis of treatment was made in 93 patients divided into three groups: conservative treatment (11 patients), operations by traditional methods (28 patients), surgery using constructions of titanium nickelide (54 operations). It was found that the conservative treatment of complete acromioclavicular end dislocation was followed by a repeated displacement, development of deforming arthrosis and deformity of the area of injury. Transcapticular fixation of acromioclavicular end dislocation resulted in the development of deforming arthrosis (68%), the incidence of this complication depending on the kind of operation. The greatest inclination of the construction to migration was noted after fixation with wires. After the application of a titanium nickelide construction the most frequent process was resorption of the bone around the construction in the shape of a hook (36%) which resulted in some patients in subluxation (11%) and development of deforming arthrosis (4.5%).
