Fatal Intraoperative Hemorrhage During Spinal Fusion Surgery for Osteogenesis Imperfecta

Osteogenesis imperfecta (OI) is an uncommon inherited systemic disorder of the connective tissues characterized primarily by varying degrees of bony fragility. Consequently, individuals affected by this condition frequently suffer severe skeletal injuries from otherwise innocuous traumatic events. This syndrome has other associated abnormalities, including hydrocephalus and brain stem compression on the basis of cranial developmental defects (platybasia), cardiac and vascular problems, respiratory disease from spinal deformities, vascular fragility, a bleeding disorder caused by an apparent platelet function abnormality, and anesthesia-related hyperpyrexia. A case is presented here of a young girl with advanced OI in whom intraoperative death occurred as a consequence of inadvertent rib fractures, with subsequent uncontrollable hemorrhage. OI may also potentially be mistaken for child abuse by an inexperienced examiner.
