MARS MRI in Revision THA With a Ceramic Femoral Head and Titanium Sleeve

Revision total hip replacement using a ceramic head utilizes a titanium sleeve which introduced another articulation into the system that may lead to a local soft tissue reaction. The purpose of this study is to determine the frequency, size and types of MRI documented local tissue reactions in individuals doing well after a revision total hip replacement and ceramic bearing surface that utilizes a titanium sleeve.

Inclusion Criteria:Patients who received a revision total hip surgery utilizing a ceramic femoral head with a titanium sleevePatient whose age ranges from 18-99Patients who are not experiencing groin pain, thigh pain, or pain with ROM of the hipPatients who are at least 2 years after a revision THAAcetabular implant (cup) was placed in the appropriate positionPatients with a Harris Hip Score of >90Exclusion Criteria:Patients who do not meet the above criteriaPatients unable to have an MRI (i.e. pacemaker, metal implants or issues with claustrophobia requiring sedation)
