Biomaterials. Secher L, Svejgaard E, Hansen GS. Unusual skin cancer linked to chronic allergy from metal orthopedic implant. [4] Although skin patch testing does not predict the stability or failure of prostheses, failure rates of joint replacement have been shown to be four times higher in patients with symptomatic metal sensitivity than in those who did not have preoperative symptoms. Biomaterials. Veien NK, Svejgaard E, Menn T. In vitro lymphocyte transformation to nickel: a study of nickel-sensitive patients before and after epicutaneous and oral challenge with nickel. Swelling, pain, draining sinuses, and inflammation at the implant site may mimic infection. 3:6. The causes of these skin immunologic reactions are unclear. [5] There is no indication for workup of asymptomatic patients with stable implants. Sometimes, a dental surgeon may inadvertently place a dental implant too close to a nerve. Hardware removal is usually done because of problems caused by the implant, such as pain or infection. 356-71. [QxMD MEDLINE Link]. zelik H, Vrana NE, Gudima A, Riabov V, Gratchev A, Haikel Y, et al. Surgically implanted devices, prostheses, grafts, and fixation materials are commonly used for joint replacement, correction of spinal pathology, repair of fractures, treatment of cardiovascular pathology, and control of chronic pain. Others may want them removed because of cancer risk or to avoid security metal detection. In a prospective cohort study that included 597 patients with metal-on-metal hip resurfacing and total hip prostheses, Hart et al found that elevated blood levels of metal (ie, chromium and cobalt) ions were associated with an increased risk of implant failure. The consequences can be simple annoyances to life-threatening systemic illness. Hypersensitivity to Orthopedic Implants: A Review of the Literature. Acta Derm Venereol. [2] : An immune response always occurs. Case example.

In the Chicago area, these tests are available at both Loyola University Medical Center and Rush Presbyterian Mecdical Center. However, in some cases, small amounts of nickel does make their way into rose gold and yellow gold alloys. J Am Acad Orthop Surg. [39] After placement of metal implants, sensitization (ie, a change from a negative result to a positive one) occurs in 2.7% of cases for chromium, 3.8% for nickel, and 3.8% for cobalt. The symptoms or signs of a rejected implant can be: systemic, meaning symptoms affecting the whole body; or; localized, meaning the affected area is limited to the area where the hernia mesh surgery was conducted (or the incision site). [QxMD MEDLINE Link]. Limited reactions can appear as a contact dermatitis on the skin that has been exposed to the metal. Correlation of allergy, metal levels, implant alloy, and implant damage in patients undergoing revision joint arthroplasties.
