The Agreement Between Radiographic And Surgical Measurements Of The Intervertebral Disc Height: A Cadaveric Study

Study Design: Retrospective observational study. Objective: To investigate the relationship between the extent of ligament ossification and the range of motion (ROM) of the lumbar spine and develop a new scoring system. Methods: Forty-three patients (30 men and 13 women) with lumbar spinal canal stenosis who underwent decompression from January to December 2018. Ligament ossification at L1/2 to L5/S was assessed on plain X-ray (Xp) and computed tomography (CT) using a modified Mata scoring system (0 point: no ossification, 1 point: ossification of less than half of the intervertebral disc height, 2 points: ossification of half or more of the intervertebral disc height, 3 points: complete bridging), and the intra-rater and inter-rater reliability of the scoring was assessed. The relationship of the scores with postoperative lumbar ROM was investigated. Result: Intra-rater reliability was high (Cronbach’s α was 0.74 for L5/S on Xp but 0.8 or above for other sections), as was inter-rater reliability (Cronbach’s α was 0.8 or above for all the segments). ROM significantly decreased as the score increased (scores 1 to 2, and 2 to 3). A significant moderate negative correlation was found between the sum of the scores at L1/2-L5/S and the ROM at L1-S (ρ = − 0.4493, P = 0.025). Conclusion: Our scoring system reflects lumbar mobility and is reproducible. It is effective for assessing DISH in fractures and spinal conditions, and monitoring effects on treatment outcomes and changes over time.

Intervertebral Disc Height

Interbody fusion is a well-recognized technique to achieve spinal fusion. The advantage of using tricortical blocks as opposed to the dowel technique is that intervertebral disc height can be restored. Both techniques can be performed either by the anterior or posterior approach. The traditional tricortical block technique has advantages over using dowels as it is a more stable construct and can restore intervertebral disc height. However, autologous bone graft has an unpredictable behavior causing potential problems of disc space collapse, forward displacement of the graft and donor bone graft site morbidity. The Hartshill horseshoe was developed to overcome these autograft problems. It is an implant that is placed within the periphery of the intervertebral disc space where the vertebral end plate is strongest to resist compression forces. It has holes that allow screw fixation of the implant to bone to provide immediate stability and a central area for bone graft where the vertebral body is most vascular to allow incorporation of such a graft. Previous reports on the Hartshill horseshoe have used autograft (single tricortical graft). This prospective study reports the clinical and radiological results of 19 patients who underwent this procedure using xenograft 2½ to 3 years postoperative. The radiological results do not show any evidence of loosening of the screws or implant nor evidence of intervertebral disc space subsidence. It was not possible to assess the exact incidence of spinal fusion.
