Editorial - Identification of Orthopaedic Wear Debris
Thomas W. Bauer, M.D., Ph.D.
Just as particles of inhaled carbon and silica are present in regional and distant lymph nodes, it has long been suspected that the particles of wear debris that seem to be the abundant byproduct of total joint prostheses also make their way into the lymphatic system and hence travel to remote sites. But how do we recognize wear debris with certainty? What is the magnitude of this suspected migration, and is it of any clinical importance?
In this issue of The Journal, three studies address migration of orthopaedic wear debris. The article by Benz et al. describes two patients in whom lymph nodes contained polarizable particles that were interpreted as being consistent with polyethylene wear debris. No coexisting metal particles were identified, and neither contralateral lymph nodes nor lymph nodes from patients without a joint implant were analyzed. The authors do not speculate on systemic responses but remind the reader . . . [Full Text of this Article]
