We present a study of the pressures developed at the bony prominences (greater trochanter, iliac crest and sacrum) when a pelvic binder was applied to 10 healthy individuals. The pressures developed between the pelvic binder and the skin over the prominences were all greater than the pressure recommended at interfaces to avoid the development of pressure sores. This suggests that patients with pelvic fractures who are treated with temporary pelvic binders are at risk of developing pressure sores. This should be recognised and the skin inspected if the binder is to be in place for a prolonged period.
