Castellani”, University of Pavia, ItalyAbstract: Osteogenesis imperfecta (OI) is the most common bone genetic disorder and it is characterized by bone brittleness and various degrees of growth disorder. Clinical severity varies widely; nowadays eight types are distinguished and two new forms have been recently described although not yet classified. The approach to such a variable and heterogeneous disease should be global and therefore multidisciplinary. For simplicity, the objectives of treatment can be reduced to three typical situations: the lethal perinatal form (type II), in which the problem is survival at birth; the severe and moderate forms (types III–IX), in which the objective is ‘autonomy’; and the mild form (type I), in which the aim is to reach ‘normal life’. Three types of treatment are available: non-surgical management (physical therapy, rehabilitation, bracing and splinting), surgical management (intramedullary rod positioning, spinal and basilar impression surgery) and medical-pharmacological management (drugs to increase the strength of bone and decrease the number of fractures as bisphosphonates or growth hormone, depending on the type of OI). Suggestions and guidelines for a therapeutic approach are indicated and updated with the most recent findings in OI diagnosis and treatment.Keywords: osteogenesis imperfecta, bone genetic disorder, bone brittleness, “brittle bone disease”, connective tissue malfunction, short stature, progressive skeletal deformities, blue sclerae, dentinogenesis imperfecta, joint laxity, adult onset deafness
