Tuberosity avulsions

Fracture which extends between the trochanters of the proximal femur

- lower limit is inferior border of lesser tuberosity

Extra capsular / well vascularized

The key to stability is the posteromedial cortex

To obtain and maintain a concentric reduction without complication

0 - 6 /12

- best time for treatment

- maintain reduction of head & allow normal acetabular development

Obtain ultrasound

Graaf 2A and 2B

- Alpha angle 50 - 59^o range

- many will resolve without treatment

Femur

- removal of femoral head cartilage

- resurfacing with metal

- cemented / uncemented

Acetabulum

- standard technique

Bearing surface

- metal on metal

Relatively young man (40 - 50)
