[Metabolic diseases of bones. Catamnestic study of the incidence and kind of problems in surgical treatment].

By a catamnestic study at Orthopedic Department of Homburg/Saar University Clinic 156 courses of variant constitutional diseases of bone (1965-1986) were recorded. The frequencies of primary spontaneous fractures, fracture healing-disturbances, refractures and pseudarthroses after operative management of bone lesions or correction-osteotomies were of special interest. While there was no increased rate of traumatic or spontaneous lesions or prolongated healing-rate in case of Rickets and M. Ollier, those complications with need of osteosynthetic measures were more often due to M. Paget and M. Jaffé-Lichtenstein. As expected, osteogenesis imperfecta represented the highest rate of osseous lesions; an uneven situation was found among multiple/generalized epi- and metaphyseal dysplasias.
