title: Dural penetration by interspinous process segmental spine instrumentation: case report.
abstract: A case of pseudo-meningocele complicating posterior spine fusion with interspinous process segmental spinal instrumentation is presented. The L rod rotated postoperatively 90 degrees and penetrated the dura. The presenting symptoms were pain accompanied by fixed lumbar and hip flexion contractures that improved dramatically after removal of the penetrating part. The unusual course as well as the treatment and recommendation for prevention are discussed.
