[Construction of a plaster collar]

A fairly simple but strictly controlled method is described for constructing a plaster collar. After a brief description of the apparatus, meticulous details are given of each technical step leading to the production of a light, perfectly molded and well tolerated apparatus. The collar is usually constructed with the patient sitting, under slight traction and with webbing straps to obtain immobilization in the exact position required. The shoulders are lowered to a maximum by making the patient hold weights. The cephalic part is first molded and then integrated solidly into the thoracic part (breastplate and backplate). A perfectly constructed apparatus provides excellent immobilization.
