MRCP revision battle 49.2: Nail-patella syndrome

Nail-patella syndrome occurs as a possible answer in a fair few MRCP questions so an insight into it is helpful...

Nail-patella syndrome affects 1 in 50,000

It is characterised by:

  • small patella
  • boney spines over posterior iliac crests (70%)
  • renal abnormalities (30-50%)
  • over-extension of joints
