A Philadelphia collar or cervical immobiliser is used to keep the neck and head in the correct position after a spinal cord injury (SCI). This gives the injured spinal column and the ligaments time to heal. It also help support the neck muscles.

TopPhil Cervical Immobiliser is made of hard plastic, with hook and loop closure. It consists of a front piece with a chin cup, and a curved back piece that fits against the lower part of the skull (head). This design and the rigid material helps to keep the neck and head in the correct position after a ‘spinal cord injury’.
