[Allergy to nickel, chromium and cobalt after osteosynthesis].
Metals are known as a common cause of contact allergies. The prevalence of sensitisation to the composite metals makes for a potential risk of osteosynthesis complications in patients suffering from long bones fractures. In the study the prevalence of delayed allergy to nickel sulphate, potassium dichromate and cobalt was estimated as well as the relation to the osteosynthesis complications. The atopy prevalence was estimated too. Persons under examination were divided into 3 groups. I--treated with osteosynthesis without complications (n = 20), II--treated with osteosynthesis with synostosis complications (n = 16) and III--negative controls (n = 34). We estimated 5% prevalence of delayed allergy to nickel in group I, 6.25% in group II and 5.8% in group III. In patients exposed to chromium we observed delayed allergy prevalence of 5.8% in group I and 3% in group III. No allergy to chromium in group II was revealed. No allergy to cobalt in all groups was revealed. The prevalence of atopy in group II was rare (6.35%) when in group I it was 45% and in controls 32%. The more frequent occurrence of type IV allergy to metals in atopic patients was not confirmed. There was no difference between the prevalence of delayed allergy to metals in groups I and II. Only one case of secondary allergy to chromium was observed.
