Posted on: 17 February, 2009

Possible Causes of Groin Pain:

From the Implant

  • Aseptic loosening
  • Femoral neck stress fracture
  • Bony impingement
  • Soft tissue impingement
  • Osteonecrosis
  • Reaction to excessive metal wear
  • Metal sensitivity

Referred Pain

  • From the pelvis, back or abdomen

Clinical Tests to Aid Diagnosis:

Haematological

  • Checks for infection (eg. ESR, CRP)
  • Serum metal ions (if available)
  • (Lymphocyte transformation tests) if available

Radiological

  • Imaging to assess fixation, implant position, and the presence of fluid build-ups or groin masses

Nuclear medicine

  • Scans to assess infection, fracture or loosening
