摘要

导言：全髋关节置换术引起的金属中毒通常是由腱鞘炎引起的，与血清钴和铬水平升高有关。方法：在此，我们报告了两例罕见的钛含量升高病例，这两例病例的发病机制相同，都是以前未报道过的钛金属中毒原因：在这些病例中，电缆和钛杆之间的接触是病因：讨论：与全髋关节置换术相关的孤立高钛金属含量报告非常罕见。这些病例说明了这种情况可能产生的新机制。

Elevated Titanium Levels After Revision Total Hip Caused by Previously Unreported Mechanism.

Introduction: Metallosis from total hip arthroplasty is usually due to trunnionosis and is associated with elevated serum cobalt and chromium levels. Titanium levels usually remain normal.

Methods: Here, we report two rare cases of elevated titanium levels, both with the same mechanism, which is a previously unreported cause of titanium metallosis.

Results: In these cases, contact between cables and the titanium stem were the source.

Discussion: Reports of isolated high titanium levels associated with total hip arthroplasty are rare. These cases illustrate a new mechanism from which this situation may arise.
