metastasis

Aim 

The identification of skeletal metastasis & fixation prior to fracture

Incidence

50% of new cancer cases have metastasis

- 1% have pathological fracture

- increasing with more aggressive palliative care

Subcapital Femoral Neck Metastasis

Fractures

Principle

- do very poorly with fixation

- hemiarthroplasty or THR

- stem should be 2.5 cortical diameters beyond any area of weakness

- THR if acetabulum involved

Definition

Benign lesion with a wide spectrum of behavior characterized by stromal cells and giant cells

Epidemiology

Common

- 20% of benign tumours

More common females

- F:M = 1.5:1

- most tumours M>F

Usually patient in 20's

- usually after skeletal maturity

- 3% < epiphyseal closure
