Injuries at the articulating surfaces of bone (chondral, osteochondral, subchondral fractures and osteochondrosis dissecans)

摘要: Fractures involving the articulating surfaces of bone are a common cause joint disability. Management options as numerous terms used to describe these lesions. These include osteochondral, transchondral, flake or chip fractures well osteochondrosis (osteochondritis) dissecans. The understanding traumatic lesions and their sequelae has been increased by modern imaging technology, especially magnetic resonance (MRI). This paper reviews mechanism injuries, incidence, clinical presentation, radiological appearance principles treatment. Hyaline cartilage, subchondral plate cancellous have be seen an anatomic unity. Subchondrally located microfractures, osteochondral solely chondral different manifestations impaction injuries at surfaces. We believe that dissecans in most cases is also result undiagnosed injury surface bone.
