Aetiology

  • Probably a growth defect in the physis and are therefore metaphyseal in long bones (usually in proximal humerus and femur), although they can occur in the talus or calcaneus

Clinical presentation

  • May be asymptomatic and an incidental finding (usually x-ray of child/YA) but can weaken the bone leading to pathological fracture

Investigations

  • Imaging - x-ray, MRI
