Abstract
1. A Nigerian patient with radiographic features of osteopathia striata, osteopoikilosis and melorheostosis is reported. Also radiographs of a patient from the Radiographic Museum of the Institute of Orthopaedics at the Royal National Orthopaedic Hospital are reproduced because they show a similar mixture of these conditions.
2. lt is probable that a common factor is present at some stage in the development of melorheostosis, osteopathia striata, osteopoikilosis and possibly osteopetrosis.
