[Errors and dangers in the treatment of fractures and pseudarthroses of the clavicle].

The rate of pseudarthrosis in 726 conservatively treated fractures of the clavicula was 0.69%. The danger of hyperporoses lies in neurovascular compression. Errors in treatment pertain to wrong operative indications and inadequate osteosyntheses. Surgery should be performed only in 2nd and 3rd degree open fractures and/or concomitant neurovascular lesions (2.06%), in distal fracture dislocations with instability of the AC-joint (1.6%) and in cases of painful pseudarthrosis (n = 46). The implant of choice is the 3.5 DCP. Six cortical contacts must be achieved in each fragment.
