Abstract
In this study the clinical results of surgery for posterior lumbar fusion by H-shaped autologous bone graft (H-graft) associated with ceramic interspinous block (CISB) are reported. The clinical results of this procedure have been excellent during the follow-up (average: 3.9±2.8 years) in all six cases. There was a marked improvement (recovery rate: 70.4%) of clinical symptoms assessed by the pre- and postoperative Japanese Orthopaedic Association low back pain score. In radiographic evaluation, the spinal alignment was maintained successfully. H-graft with CISB is a non-instrumentation, segmental fusion and decompression surgery. We believe that those most suitable for this method are young adults suffered from spondylolysis combined with upper adjacent level disc degeneration (type III), insufficient union after anterior interbody fusion (ALIF) or segmental stenosis with instability.
