Pathological fracture risk (Harrington criteria)

Dr Henry Knipe et al.

Harrington criteria can be used to predict which skeletal metastases are at high risk of pathological fracture and should undergo prophylactic internal fixation. It preceded the Mirel classification for impending pathological fracture but has not been validated and its use is debated.

Classification

  • >50% cortical bone destruction
  • lesion >2.5 cm in size
  • pathological avulsion fracture of the lesser trochanter
  • functional pain after radiation therapy

Bone tumours

The differential diagnosis for bone tumours is dependent on the age of the patient, with a very different set of differentials for the paediatric patient.
