Abstract
1. A child with so-called ischio-pubic osteochondritis is reported from whom the affected ramus was resected. The features observed in the resected specimen were those of a normal closing epiphysis.
2. The literature is reviewed with emphasis on other children who had biopsies and on large scale radiographic surveys of normal children.
3. The conclusions are that the changes in the ischio-pubic synchondrosis cannot justifiably be called osteochondritis, and that they require further investigation, which can most profitably be done at necropsy.
