Clinical History, Examination and Blood Test Result

  • Case 8 is a 48-year-old make who presented with left groin pain.

  • At 26 he injured his left rectus femoris playing football, requiring reconstruction. This started to cause him pain in his late 30’s and he was treated with femoral nerve neurolysis. This provided partial relief.

  • In 2011 he had a left Birmingham hip resurfacing completed which provided partial pain relief also.

  • He presented with an audible click in his left hip with flexion and internal reduction and the inability to adduct fully. He had a normal gait and was able to straight leg raise however this caused pain.

  • An injection of local anaesthetic received his pain for 24 hours.

  • He had a CRP of 2.2mg/L and an ESR of 16mm/H ruling out infection and his blood metal ion levels were satisfactory.

This pre-operative anteroposterior radiograph shows satisfactory sizing, positioning and fixation of the left Birmingham hip resurfacing.

  • An MRI scan revealed rectus femoris problems, which are long standing, but also psoas atrophy.


  • Left groin pain secondary to psoas tendonitis due to the psoas tendon rubbing on the inferior margin of the hip resurfacing head.


  • Revision of the Birmingham hip resurfacing, reducing the size of the femoral head to 36mm while maintaining stability with a longer neck.

  • A Corail femoral stem was used with a ceramic head. A Pinnacle Gription socket was used with a polyethylene liner and 3 screws for initial stability.
