Case report: vertebral compression fracture in a fused and instrumented lumbar segment.

Although vertebral fractures in fused spinal segments have been reported, we are not aware of any descriptions of vertebral body compression fractures in solidly fused and instrumented segments. We report a patient who sustained a vertebral-body compression fracture of the L1 vertebra in an instrumented and fused spinal segment from T10 to L5. The fracture occurred during self-insertion of a rectal suppository. No intervention was required to treat the fracture, and there was no long-term clinical effect.
