A Philadelphia collar is used to immobilize the neck after trauma, injury or surgery, to keep the cervical spine still while it heals. The collars from GSTC are manufactured as radiolucent so that they do not interfere with X-rays, CT scans or MRI imaging. The anatomical fit and multiple size options cater to a variety of patients, from post-operative recovery to whiplash care. The collar provides the firm support that hospitals and rehab centers want for critical healing periods.
