摘要
本研究选取128例低位颈椎骨折脱位的患者,分成4组:完全瘫痪,不完全瘫痪,根性损伤,无脊髓神经损伤。测量初次X线片骨折脱位处椎管最小矢状径及相邻的未损伤节段椎管矢状径、Pavlov值。结果:损伤节段椎管最小矢状径;除C组与D组外,其余各组间相差十分显著。未损伤节段椎管矢状径、Pavlov值:A、B组与C、D组间分别有显著、十分显著差异。本文通过定量研究表明:脊髓的损伤程度与骨折脱位部位椎管最小矢状管径有关;永久性脊髓伤的患者在损伤发生前就已存在颈椎管狭窄;颈椎骨折脱位时颈椎管较宽者比较窄者更可能幸免于脊髓神经损伤。
We analyzed 128 patients of three factors involved in fractures and dislocations of the cervical spine and their relationships to the degrees of injury of the spinal cord. The three factors were the space available for the spinal cord at the level of the injury (SASCI), the sagittal diameter of the spinal canal at the uninjured levels (SD-SCU) and the Pavlov ratio at the uninjured levels (PRU). We got four groups; Group A, complete injury of the spinal cord , 44 cases ; Group B, incomplete injury of the spinal cord , 50 cases; Group C, isolated nerve-root injury, 9 cases; Group D. no neurological deficit, 21 cases. The difference of the mean SASCI between the groups was significant (P<0. 01) except that between Group C and Group D. The mean SDSCU of Group A and Group B was significantly different from that of Group C and Group D (P<0. 05) while the mean PRU being remarkably significant (P<0. 01). These findings demonstrated quantitatively that the severity of the injury of the spinal cord was partially associated with the space available for the cord after the injury, as measured on plain lateral radiographs. In addition the patients who sustained a permanent injury of the cord had a narrower sagittal diameter of the spinal canal before the injury. Compared with those who have a narrower canal, patients who had a larger sagittal diameter of the canal may be more likely spared for a permanent injury of the spinal cord following a fracture or dislocation of the cervical spine.
