Which incomplete spinal injury has the worst prognosis?

• A. Posterior Cord Syndrome
• B. Central Cord Syndrome
• C. Brown-Sequard Syndrome
• D. Anterior Cord Syndrome

Answer: (D)

In incomplete spinal cord injuries, prognosis hinges on which tracts are damaged. Anterior cord syndrome occurs when the anterior spinal artery is affected, leading to loss of motor function and loss of pain and temperature sensation below the injury, with preserved vibration and proprioception. Because the major motor pathways and spinothalamic tracts are involved, the deficits are broad and the potential for meaningful recovery is limited, making this pattern the worst prognostically among the common incomplete syndromes. By contrast, posterior cord syndrome mainly disrupts the dorsal columns, causing loss of vibration and proprioception but sparing motor function, so mobility is often preserved and recovery tends to be better. Central cord syndrome typically has greater weakness in the upper extremities with variable recovery and can improve with rehabilitation. Brown-Sequard involves a hemicord injury with ipsilateral motor and vibration loss and contralateral pain and temperature loss, but many patients retain substantial functions and recover well. Thus, anterior cord syndrome carries the bleakest prognosis among these incomplete injuries.
