Resin injection of thoracic paravertebral spaces.

Stained, quick setting resin was injected into the thoracic paravertebral spaces of six cadavers to assess the suitability of this material for delineating the spread of injected substances in an area of the human body which is being re-evaluated currently as a repository for analgesic drugs. The distribution and spread of the resin in relation to intercostal spaces, vertebral bodies and the spinal cord were noted, and compared with other studies.
