Abstract:
Metal-on-metal (MoM) hip resurfacing/replacement is a highly discussed topic in arthropathy, and the impact of its complications is still being elucidated. We report the case of a patient who presented with severe stomach pain due to a symptomatic psoas fluid collection that was later shown to communicate with a MoM total hip prosthesis. A MoM pseudotumor presenting as persistent stomach pain due to an aseptic psoas fluid collection is a rare complication. The case may support an earlier diagnosis in at-risk patients, and it outlines a suggested workup and treatment plan.
Insights
Metal-on-metal hip implants can cause rare complications like pseudotumors. This case highlights a symptomatic psoas fluid collection linked to a hip prosthesis, suggesting earlier diagnosis for at-risk patients.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Medical Case Reports
Background:
- Metal-on-metal (MoM) hip prostheses are utilized in arthroplasty, but their complications require ongoing investigation.
- Pseudotumor formation is a known, albeit infrequent, complication associated with MoM hip implants.
