metastasis

Background

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

 

Specific Management

Subcapital Femoral Neck Metastasis

 

Femoral Neck Metastasis MRIMetastasis Proximal Femur

 

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

 

Giant Cell Tumour of Bone

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
