title: Surface strain distribution in isolated single lumbar vertebrae.
abstract: The surface strains of isolated single lumbar vertebrae under compressive load were examined by the techniques of brittlecoat and photoelastic analysis. Directions of principal strain components have been determined. Areas of stress concentration were found around the vertebral rims, near the pedicles, and around the foramina of the basivertebral veins.
