Pseudobursae are irregular recesses around a joint that can occur following a joint replacement or surgery. They usually communicate with the joint but may track considerable distances around the joint. They may be associated with infection but can also be incidental finding.

They may be present in up to 43% patients following hip joint replacements 4.

They are typically described around the hip, and locations include:

  • greater trochanteric region: considered most common 2
  • supra-acetabular region
  • iliopsoas region
  • pseudobursitis:
    • may be treated conservatively with steroid and anesthetic injections
    • the presence of irregular walls, sinus tracts, bone destruction, or debris in the cavity suggest infection
    • aspiration and injection of local anesthetic may provide symptomatic relief, and if symptoms recur and if aspiration cultures are negative, steroid injections may help
