|
Most common- below carpus/tarsus-->foot
Uses: P1/P2 Fractures, Fetlock luxation Pressure points: Top of cast, sesamoids |
|
|

|
2-3 4/6 mm positive profile pins at 30* divergence incorporated into cast
Uses: comminuted fractures of lower limb Breakdown injuries of fetlock Pressure points: around pins |
|
|
What are principles of cast monitoring?
