Secondary Spinal Cord Injury llI: Pathophysiology

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Summary

Contralateral C7 nerve root transfer (cC7) surgery can restore shoulder and upper limb function in patients with long-term post-stroke flaccidity. This innovative approach reduced shoulder subluxation and improved muscle strength in two cases.

Area of Science:

Neurosurgery
Rehabilitation Medicine
Stroke Recovery

Background:

Prolonged flaccidity after stroke is challenging, with limited recovery options.

Keywords:

Contralateral C7 nerve transfer Flaccid paralysis Stroke Subluxation

Shoulder subluxation is common due to weakened shoulder abductor muscles (C5 nerve root).

Ipsilateral nerve and muscle reconstruction is often limited by hemiplegia.
