Clinical and radiological outcomes of spinal cord injury without radiologic evidence of trauma with cervical disc herniation

Abstract

CDH in most patients with SCIWORET likely occurred before rather than after trauma. CDH caused more severe cord compression but did not aggravate the neurologic injury. The extent of MSCC had no association with the initial neurologic deficit or final recovery.

The Role of Magnetic Resonance Imaging to Inform Clinical Decision-Making in Acute Spinal Cord Injury: A Systematic Review and Meta-Analysis

“…The rate of disc injury ranged from 4% to 42% in studies involving cervical SCIWORA, whereas it was 40% to 88% in other SCI studies [ 20 , 21 , 23 , 25 , 26 , 27 , 28 , 30 , 31 , 32 , 33 , 37 , 41 , 42 , 43 , 44 ]. Disc herniation was present in 37% to 100% of patients with SCIWORA, whereas it was present in 24% to 100% in SCI [ 20 , 21 , 23 , 25 , 26 , 27 , 28 , 30 , 31 , 32 , 33 , 37 , 41 , 42 , 43 , 44 ]. Disc herniation causing cord compression varied from 3% to 83% in two studies involving SCI [ 23 , 30 ].…”

“…Overall, 28 studies relevant to KQ2 were identified, reporting the frequency of certain pathological MRI findings in various types of SCI ( Table 4 ) [ 17 , 18 , 19 , 20 , 21 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ].…”

“…Thirteen studies provided data on the frequency of ligamentous injury, all in patients with cervical SCI [ 17 , 18 , 20 , 24 , 25 , 26 , 27 , 28 , 29 , 34 , 37 , 41 , 43 ]. Among these studies, nine focused on patients with SCIWORA, in which the frequency of ligamentous injury ranged from 0 to 100% [ 20 , 24 , 25 , 26 , 27 , 28 , 34 , 37 , 41 ].…”

The pooled frequency of ligamentous injury in SCIWORA was 36% (145/404 across eight studies excluding [ 18 ] due to overlapping cohort with [ 17 ]), but heterogeneity across studies was high (I 2 = 0.94, p < 0.001).…”

“…Sixteen studies provided data on the frequency of disc herniation and/or injury in SCI, including 15 in cervical injuries and one including all spinal levels [ 20 , 21 , 23 , 25 , 26 , 27 , 28 , 30 , 31 , 32 , 33 , 37 , 41 , 42 , 43 , 44 ].

Disc herniation was present in 37% to 100% of patients with SCIWORA, whereas it was present in 24% to 100% in SCI [ 20 , 21 , 23 , 25 , 26 , 27 , 28 , 30 , 31 , 32 , 33 , 37 , 41 , 42 , 43 , 44 ].…”
