摘要

A 6 month-old boy fractured his right tibia, when he fell from a couch (50 cm height). One month later, he accidently kicked his leg against a desk. He was diagnosed with a frac- ture of the rig ht femur. The following month, he again fell from a couch, sustaining a new frac ture of the right femur. In addition to the frac ture, his x-ray showed thin, osteopenic bones (Figure 1). At the age of 11 months, the boy was assessed in our in- stitution, in order to reac h a diagnosis which would explain his three low-energy fractures. An eye check revealed blue sclera, hear t sounds were nor mal, as wer e his teeth. His full metabolic bone profile (Table 1), showed low levels of procol- lagen type 1 C-ter minal propeptide (PICP).
