Abstract Background: Cervical spinal cord injury(CSCI) without major fracture or dislocation is often described as cervical SCI without radiographic abnormality (SCIWORA). Majority of this injury could be without radiographic abnormality but with disrupted anterior longitudinal ligament or intervertebral disc unless examined by MRI. The optimal surgical management of this cervical spinal cord injury remains controversial. This study is to evaluate the clinical advantages of laminoplasty combined with short-segment transpedicular screw fixation for managing this issue. Methods: SCIWORA patients were collected into two groups according to different surgical methods. Patients in group A received laminoplasty combined with transpedicular screw fixation, and patients in group B received anterior cervical fusion combined with laminoplasty. All cervical spine were assessed by X-ray, CT, MRI preoperatively and postoperatively to evaluate the decompression range, bonegraft fusion and instruments location. ASIA grade and JOA score were recorded to assess the neurological function recovery. Complications, surgery time, intraoperative blood loss and hospital stay were compared between two groups. Mean follow-up was at least 2 years. Results: In this study, Forty eight patients were in group A and 54 ones were in group B. All cases were decompressed fully and obtained fusion 6-month postoperatively. The ASIA grade was improved postoperatively, but no significantly different between two groups (p=0.907). The JOA was 6.12±1.76 preoperatively and improved to 11.98±2.98 postoperatively with the 53.13% neurofunction recovery rate in group A, with no significantly different compared with group B(vs 6.63±2.45, p=0.235; vs 12.62±3.59, p=0.303; vs 57.76%, p=0.590)respectively. Total 18 complications occurred but the occurrence was significant lower in group A(p=0.020). The average surgery time was 2.2±0.32 hours, intraoperative blood loss was 304±56ml and hospital stay was 8.2±3.1 days, significantly decreased compared with group B(vs 3.1±0.29, p=0.000; vs 388±61ml, p=0.000; vs 12±2.8days, p=0.000)respectively. Conclusions: Cervical laminoplasty combined with short-segment transpedicular screw fixation is a reliable option to treat SCIWORA patients with CSS. The advantages include achieving sufficient cervical decompression, maintaining cervical stability and avoiding extra anterior cervical fusion which increases surgery time, intraoperative blood loss, postoperative complications and hospital stay.

Abstract OBJECTIVE Although several clinical applications of transpedicular screw fixation in the cervical spine have been documented recently, few anatomic studies concerning the cervical pedicle are available. This study was designed to evaluate the anatomy and adjacent neural relationships of the middle and lower cervical pedicle (C3–C7). The main objective is to provide accurate information for transpedicular screw fixation in the cervical region and to minimize complications by providing a three-dimensional orientation. METHODS Twenty cadavers were used to observe the cervical pedicle and its relationships. After removal of the posterior bony elements, including spinous processes, laminae, lateral masses, and inferior and superior facets, the isthmus of the pedicle was exposed. Pedicle width, pedicle height, interpedicular distance, pedicle-inferior nerve root distance, pedicle-superior nerve root distance, pedicle-dural sac distance, medial pedicle-dural sac distance, mean angle of the pedicle, root exit angle, and nerve root diameter were measured. RESULTS The results indicate that there was no distance between the pedicle and the superior nerve root and between the pedicle and the dural sac in 16 specimens, whereas there was a slight distance in the lower cervical region in the 4 other specimens. The mean distance between the pedicle and the inferior nerve root for all specimens ranged from 1.0 to 2.5 mm. The mean distance between the medial pedicle and the dural sac increased consistently from 2.4 to 3.1 mm. At C3–C7, the mean pedicle height ranged from 5.2 to 8.5 mm, and the mean pedicle width ranged from 3.7 to 6.5 mm. Interpedicular distance ranged from 21.2 to 23.2 mm. The mean root exit angle ranged from 69 to 104 degrees, with the largest angle at C3 and the smallest at C6. The mean angle of the pedicle ranged from 38 to 48 degrees. The nerve root diameter increased consistently from 2.7 mm at C3 to 3.8 mm at C6 and then decreased to 3.7 mm at the C7 level. Differences in measurements were considered statistically significant at levels ranging from P < 0.05 to P < 0.01. CONCLUSION This study indicates that improper placement of the pedicle screw medially and superiorly in the middle and lower cervical spine should be avoided and that the anatomic variations between individuals should be established by measurement.
