Adolescent boys
Proximal tibia / primary ossification centre
Tibial tuberosity / secondary ossification centre
- eventually merges with primary ossification centre
Type I - Tibial tuberosity ossification only
Position
- patient supine on radiolucent table
- place ECG lead and artery clip over centre of femoral head
- useful to put II ipsilateral to leg, and place knee on cassette
Most common long bone fracture
Young patients / sports
Elderly / simple falls
MVA - often compound
Grade 0
- nil ST injury
Grade 1
Supracondylar fracture of humerus
Both bone forearm fractures
Increased pressure within a closed fibro-osseous space
Seen in athletes, associated with repetitive exertion
Leg
1. Anterior compartment
- anterior tibial artery
- deep peroneal nerve
Circulation of tissues within a closed osteofascial space are compromised by increased pressure within that space
Most common
- anterior leg compartment
- flexor compartment forearm
- deep posterior leg compartment
Prerequisite is volume restricting envelope
- fascia & skin
- POP
- dressings
1. Increased contents
Bleeding / edema
- fracture
