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

January 13, 2023 updated by: Jason Jennings, Colorado Joint Replacement

Metal Artifact Reduction Sequence MRI in Revision Total Hip Arthroplasty 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.

Detailed Description

Metal-on-metal total hip arthroplasty (THA) were heralded as a solution for two of the most common problems in hip arthroplasty in the last decade, instability and osteolysis. Unfortunately, their failures have led to diminished enthusiasm for this bearing surface. Adverse local tissue reactions (ATLRs) have been well documented as a means of pain and failure in this population. A recent report revealed that the most commonly used bearing surface in total hip arthroplasty, metal-on-polyethylene, may have up to a 28% incidence of MRI abnormalities in asymptomatic hips. Revision THA 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 asymptomatic individuals after a revision THA and ceramic bearing surface that utilizes a titanium sleeve. To our knowledge, this has not been studied previously and may provide important baseline features of this diagnostic tool with this particular bearing surface. We hypothesize that there will be fluid collections in a small but clinically significant portion of asymptomatic patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
