distal radius

Definition

Unacceptable position of radius post fracture

1.   Radial Shortening > 4mm at DRUJ

2.   Radial Inclination < 15°

Epidemiology

2 groups

1.  Elderly

- low velocity injury

- osteoporotic

- need to start bisphosphonates

2.  Young patients

- high velocity injury

Anatomy

Distal Radius Angles

- radial volar tilt 11°

- radial inclination  22°

- radius is 11 mm longer than ulna 

- ulna variance 2mm positive on average

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
