Managing metal hypersensitivity in joint replacements lacks consensus. This review analyzes orthopedic literature to propose an algorithm for diagnosing and treating patients with suspected metal allergies, emphasizing conservative care before device removal.
Area of Science:
- Orthopedic Surgery
- Allergy and Immunology
- Biomaterials Science
Background:
- Growing recognition of metal sensitivity as a complication in orthopedic joint replacements.
- Lack of established guidelines for evaluating and managing patients with suspected metal implant allergies.
- Importance of addressing patient-reported hypersensitivity reactions to metal-containing joint devices.
Purpose of the Study:
- To analyze the current orthopedic literature on the diagnosis, testing, and management of metal hypersensitivity in joint replacement patients.
- To propose a management algorithm for metal hypersensitivity specifically for patients receiving alloplastic temporomandibular joint replacements.
Main Methods:
- Comprehensive review of the orthopedic literature using PubMed searches focused on metal sensitivity in joint replacement.
- Analysis of diagnostic methods, including in vivo skin patch tests and in vitro lymphocyte transformation tests.
- Evaluation of current management strategies, from conservative approaches to device explantation.
Main Results:
- Metal hypersensitivity is often a diagnosis of exclusion, requiring thorough investigation of other potential causes.
- Skin patch and lymphocyte transformation tests are the most common diagnostic tools.
- Conservative management and exclusion of alternative diagnoses are recommended before considering device removal.
Conclusions:
- Pre-operative testing may be beneficial for patients with a history of metal intolerance or prior reactions to metal implants.
- Current literature does not support routine metal hypersensitivity testing for all joint replacement candidates.
- A structured approach is needed for managing suspected metal hypersensitivity in orthopedic implant patients.

Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
