Scientists verify hip classification systems reliability

Scientists have verified the validity of a hip classification system used for young people suffering from cerebral palsy.

The six-grade ordinal scale used to pigeon-hole hip morphology in adolescents with cerebral palsy in whom the tri-radiate cartilage was closed, is based on a number of factors, including: the assessment of Shenton's arch, deformity of the femoral head, acetabular deformity and pelvic obliquity.

Published in the Journal of Bone and Joint Surgery, the research, entitled simply The Cerebral Palsy Hip Classification is Reliable, showed that the system had excellent inter- and intra-observer reliability.

"The inter- and intra-observer reliability was assessed using the intra-class correlation coefficient and found to be excellent, with it ranging from 0.88 to 0.94," the researchers claimed.

They added: "We believe that [the system] can now be used in studies describing the natural history of hip displacement in cerebral palsy, in outcome studies and in communication between clinicians."

Speaking at the 10th European Federation of National Associations of Orthopaedics and Traumatology Congress in Vienna, Austria, at the start of this year, Kristina Akesson claimed that accurate patient assessment increases the chances of successful rehabilitation of osteoporosis, reported Ortho Supersite.
