Metal Allergy in Scoliotic Patients treated by subcutaneous Harrington Intrumentation

Aim. To investigate metal allergy in scoliotic patients with Harrington rod. Method. 25 patients treated for infantile and juvenile idiopathic scoliosis with subcutaneous Harringotn instrumentation in the Department of Orthošedics, Clinical Hispital Center Zagreb tested for metals (chromium, nickel, cobalt and scrapings of harrington rod) by epicutaneous patch test. Results. Histological analysis of the tissue around a metal harrington rod (GR) established the presence of delayed type hypersensitivity cells and metal debris. Patch testing for metals yielded positive results in 6 patients (25%). Conclusion. It may be advisable to perform patch or other sensitization test before surgical intervention of Harrington rod. In case of positive results, metal alloy safe against allergic hipersensitivity should be used to eliminate the risk of complications caused by allergic reaction to metal implant.
