Brain abscess as a complication of halo traction.

The occurrence of a brain abscess as a complication of halo traction and immobilization in the management of scoliosis is reported. Previous reports suggest that this complication is rare. Unique in this case is the development of an intracerebral abscess without skull perforation by the halo device and without evidence of contiguous spread of infection. Attention of clinical signs (headache) and the use of computerized axial tomography may allow for early detection and appropriate care.
