A Comparison of Large Diameter Metal Heads vs. Small Diameter Metal Heads vs/ Dual Mobility Total Hip Replacements
This trial is active, not recruiting.
|Condition||total hip replacement|
|Treatment||metal ion levels|
|Start date||December 2013|
|End date||May 2017|
|Trial size||200 participants|
|Trial identifier||NCT02049892, 13-002050|
Does having a large diameter metal on polyethylene total hip replacement increase metal ion release. Larger metal heads are thought to have increased torsional forces on the trunion which would like release more metal ions. Increased metal ion levels have been associated with adverse local tissue reactions. Are there any differences comparing these groups to a dual mobility type total hip replacement.
Metal Ion levels
time frame: 2 years
Male or female participants from 18 years up to 100 years old.
Inclusion Criteria: - One total hip replacement, either a large metal head (>40) or a small metal head (<30) on a polyethylene bearing surface. - 2 to 5 years s/p surgery minimum. No symptoms Exclusion Criteria: - Any other bearing surface besides metal on poly, no other joint replacements, symptomatic
