Zusammenfassung

PURPOSE OF THE STUDY: Excentration of the hip is one of the main orthopedic complications of ante and perinatal cerebral palsy. Excentration can progress to dislocation even if tenotomy is performed. What is the prevalence and morbidity of hip excentration? METHODS: We reviewed the pertinent literature on the prevalence and morbidity of hip excentration in patients with cerebral palsy based on the Medline and Reedoc databases. RESULTS: Data presented in the literature vary greatly. Populations are representative of the referral network of the teams reporting the study rather than the cerebral palsy population in general. Signs reported were pain, difficult nursing procedures, difficult sitting position, pressure sores and fractures, but only one sign can be taken fully into account: 50 p. cent of the dislocated hip joints were painful. DISCUSSION: No one study gives a precise assessment of the prevalence of hip excentration and displacement and its consequences in patients with cerebral palsy. In a population of quadriplegic patients who do not walk, the question is whether complementary tenotomy should be performed, knowking the difficult operative and postoperative situation of such procedures. In this population, walking is an exceptional goal of bone surgery, pain relief and patient comfort are more common goals. Data in this literature (50 p. 100 of the dislocated hips are painful) suggest a prudent approach. However, there is no known marker which can be used to distinguish hips which will become painful from those which will remain pain free. In addition, irreversible cartilage degeneration can cause pain contraindicating reconstructive surgery.
