The association between metal allergy, total knee arthroplasty, and revision.
Abstract Background and purpose - It is unclear whether delayed-type hypersensitivity reactions against implanted metals play a role in the etiopathogenesis of malfunctioning total knee arthroplasties. We therefore evaluated the association between metal allergy, defined as a positive patch test reaction to common metal allergens, and revision surgery in patients who underwent knee arthroplasty. Patients and methods - The nationwide Danish Knee Arthroplasty Register, including all knee-implanted patients and revisions in Denmark after 1997 (n = 46,407), was crosslinked with a contact allergy patch test database fr...

Cefazolin use in patients who report a non-IgE mediated penicillin allergy: a retrospective look at adverse reactions in arthroplasty.
CONCLUSION: surgical patients with reported non-IgE allergic reactions to penicillin have a low chance of adverse reaction to perioperative administration of cefazolin. Only a fraction of surgical patients with reported non-IgE mediated reactions to penicillin receive cefazolin perioperatively. PMID: 23576929 [PubMed - indexed for MEDLINE]

Does platelet-rich plasma have a role in the treatment of osteoarthritis?
Publication date: Available online 7 July 2015 Source:Joint Bone Spine Author(s): Paul Ornetti, Geoffroy Nourissat, Francis Berenbaum, Jérémie Sellam, Pascal Richette, Xavier Chevalier Platelet-rich plasma (PRP) has been generating considerable attention as an intra-articular treatment to alleviate the symptoms of osteoarthritis. Activated platelets release a host of soluble mediators such as growth factors and cytokines, thereby inducing complex interactions that vary across tissues within the joint. In vivo, PRP may promote chondrocyte proliferation and differentiation. The available data are somewhat conflicti...

Contact dermatitis to cobalt chloride with an unusual mechanism
Conclusion: This case report may serve to remind doctors to be aware of potential allergic reactions to prostheses and to enable them to recognize a metal allergy if it appears. Prosthetists should also be reminded of potential allergic reactions. Clinical relevance Cobalt can be used as an accelerator in making a prosthetic socket. Several cases have been reported concerning allergies to components of the prosthetic socket. This is the first report of sensitization to cobalt which is used in making a prosthetic leg.

Addition of antibiotics to bone cement for septic prosthesis exchange.
Abstract OBJECTIVE: Decontamination of periprosthetic infections by local antibiotic therapy with maximum dosing. Commercially available bone cement is used as the carrier material. Bone cement containing antibiotics is an established procedure in orthopedics for the fixation of cemented implants in artificial joint replacement. It is part of the primary and revision endoprosthetic treatment together with systemic administration of antibiotics for routine local antibiotic prophylaxis. INDICATIONS: Bone cement containing antibiotics is used in the treatment of periprosthetic infections for two-stage septic exc...

Fixed angle carbon fiber reinforced polymer composite plate for treatment of distal radius fractures : Pilot study on clinical applications.
CONCLUSION: First experience with PEEK plate osteosynthesis demonstrate quick clinical implementation with good clinical outcome and the advantage of excellent postoperative radiological assessment. At early follow-up PEEK even showed a trend for improved functional results. PMID: 26507986 [PubMed - as supplied by publisher]

Pre-operative diclofenac HPβCD for pain control of needle biopsy in musculoskeletal neoplasm: preliminary results.
We present the clinical results of a non-randomized study of two eterogeneous groups of patients: "Experimental" Group (1): diclofenac HPβCD 50 mg via s.c. one hour before surgical procedure, local anesthesia and ev. diclofenac HPβCD 50 mg via s.c. 12 hours postoperative; "Conventional" Group (2): local anesthesia and ev. postoperative tramadol 100 mg via oral for pain control. In October 2014, at the Department of Orthopedic Oncology and Reconstructive Surgery of Florence, 37 musculoskeletal biopsies for a bone or a soft tissue lesion were performed. Exclusion criteria for this study were: known allergies to lidocaine, ...

Metal Hypersensitivity and Total Knee Arthroplasty.
Authors: Lachiewicz PF, Watters TS, Jacobs JJ Abstract Metal hypersensitivity in patients with a total knee arthroplasty (TKA) is a controversial topic. The diagnosis is difficult, given the lack of robust clinical validation of the utility of cutaneous and in vitro testing. Metal hypersensitivity after TKA is quite rare and should be considered after eliminating other causes of pain and swelling, such as low-grade infection, instability, component loosening or malrotation, referred pain, and chronic regional pain syndrome. Anecdotal observations suggest that two clinical presentations of metal hypersensitivity may...

Quantitative in vivo biocompatibility of new ultralow ‐nickel cobalt–chromium–molybdenum alloys
ABSTRACT Nickel (Ni) eluted from metallic biomaterials is widely accepted as a major cause of allergies and inflammation. To improve the safety of cobalt–chromium–molybdenum (Co–Cr–Mo) alloy implants, new ultralow‐Ni Co–Cr–Mo alloys with and without zirconium (Zr) have been developed, with Ni contents of less than 0.01%. In the present study, we investigated the biocompatibility of these new alloys in vivo by subcutaneously implanting pure Ni, conventional Co–Cr–Mo, ultralow‐Ni Co–Cr–Mo, and ultralow‐Ni Co–Cr–Mo with Zr wires into the dorsal sides of mice. After 3 and 7 days, tissues around th...

Metal allergy in shoulder arthroplasty patients
Introduction: Metal allergy is an uncommon and poorly understood cause of persistent pain and failure of orthopaedics implants with no standardized criteria for diagnosis. The majority of reactions to implants are thought to be related to a Type-IV delayed hypersensitivity reaction from metallic ions from the implant. The most commonly reported allergy is to nickel although other metal allergies have also been described. Most descriptions of metal allergy in orthopaedics are from hip and knee arthroplasty literature.

Allergies in orthopaedic and trauma surgery
Publication date: Available online 30 December 2016 Source:Orthopaedics & Traumatology: Surgery & Research Author(s): C.H. Lohmann, R. Hameister, G. Singh Hypersensitivity reactions to implants in orthopaedic and trauma surgery are a rare but devastating complication. They are considered as a delayed-type of hypersensitivity reaction (type IV), characterized by an antigen activation of sensitized T-lymphocytes releasing various cytokines and may result in osteoclast activation and bone resorption. Potential haptens are originated from metal alloys or bone-cement. A meta-analysis has confirmed a higher prob...
