In orthopaedic clinical practice hip pain is the main complaint of adults with cerebral palsy (CP). The aim of this descriptive study was to specify prevalence of hip pain and to propose methods of care other than surgery. The study was a cross sectional multicentre one based in the Rhône-Alpes region. Patients over 15 years of age, with CP who were non-ambulatory were included. Two hundred and thirty-four patients were questioned. Mean age of the patients was 27 years 10 months, median 26 years 1 month, with 59.3% males and 40.7% females. Patients were questioned about pain with precise information about the circumstances of pain, tolerance, and treatment. Pain was judged to be intolerable if it prevented usual activities. Prevalence of hip pain was 47.2%. Pain was judged to be tolerable in 35.6% of the 234 patients, i.e. in 75.5% of patients with hip pain. There were three types of pain: provoked pain, pain linked to position, and spontaneous pain. Medical treatment was given to only 13.6% of patients with hip pain. The first treatment for hip pain is to avoid circumstances where pain occurs; medical treatment is reserved for when daily life cannot be adapted sufficiently to prevent pain. Medical treatment must be appropriate with doses of adequate strength before proposing surgery.
