In order for the Ponseti method to be successful it is essential that the casting process is carried out correctly. Casting materials you will need are: a thin layer of cotton padding and plaster of Paris. You may need to experiment with different types of materials in order to find the ones that work best. For example: if the padding is too thick the foot will be difficult to feel and manipulate and the cast will not hold it in the corrected position well. If the plaster does not set quickly enough it may again be difficult to hold the corrected position and if it is too heavy it can slide down the leg, applying pressure in the wrong places and sometimes causing skin ulcers.
Please refer to the Global HELP manual for full details of how to carry out the casting.
