Aspen® Pediatric Cervical Collar has been carefully designed to provide effective motion restriction without producing the painful pressure points that lead to skin breakdown and noncompliance. * Three layers of polyethylene combine to produce a support structure that is extremely rigid yet able to flex at its edges to conform to each patient"s anatomy. * This layered design spreads the load over a large area, producing a true custom fit, which has been documented not to produce pressure in excess of capillary closing pressure, the underlying cause of skin breakdown.
