Hip is one of the troublesome joint in patients with cerebral palsy (CP). Pathological mechanism of the disease must be fully understood for an appropriate approach to hip problems in this patient group. Muscle imbalances in hip which is normal at birth and bone deformities due to these imbalances cause progressive displasia. Clinical manifestations of displasia may range from hip with subluxation risk to painful dislocated hip. Especially in early period, clinical examination is not reliable, thus AP radiographical examination of hip is mandatory to determine the hip under risk. With the recognition of the hip progressing for a subluxation (abduction less than 30° and migration index greater than 25%) preventive soft tissue lengthening procedures must be planned. Hip reconstruction procedures are required in patients with intact cartilage having migration index greater than 60%. Salvage surgical interventions must be planned for neglected patients with complete maturity.
