Spinal cord injury surgery

Spinal Cord Injury (SCI) Surgery

Surgical intervention in SCI focuses on decompression, stabilization, and optimization of neurological recovery.

- Spinal instability - Progressive neurological deficits - Compression of the spinal cord or nerve roots - Fracture-dislocations - Penetrating injuries (select cases)

see Laminectomy for Spinal Cord Injury

- Decompression: Relieve pressure on the spinal cord. - Stabilization: Restore and maintain spinal column alignment. - Facilitation of Early Mobilization: Reduce complications. - Potential Enhancement of Recovery: Limit secondary injury.

- Removal of the vertebral lamina to decompress the spinal cord. - May include duraplasty to lower intrathecal pressure.

- Removal of disc material or vertebral body (corpectomy) with fusion. - Especially in cervical injuries.

- Laminectomy and posterior instrumentation (rods and screws). - Used for thoracic or lumbar injuries.

- Combined anterior and posterior approaches for severe instability.

- Endoscopic or percutaneous fixation in select cases.

- Early Surgery (<24 hours): Better neurological and functional outcomes. - Delayed Surgery (>24–72 hours): Sometimes necessary based on patient factors.

- Infection - Implant failure - Dural tears - Worsening of neurological function - Hematoma - Nonunion (pseudarthrosis)

Surgery in spinal cord injury is aimed at decompressing the neural elements, stabilizing the spine, and facilitating recovery. Optimal surgical timing, approach, and patient selection are critical for maximizing outcomes.



After traumatic spinal cord injury (TSCI), laminectomy does not improve intraspinal pressure (ISP), spinal cord perfusion pressure (SCPP) or the vascular pressure reactivity index (sPRx) at the injury site sufficiently because of dural compression.

21 patients with acute, severe TSCI had realignment of the fracture and surgical fixation; 11 had laminectomy (laminectomy group) and 10 had laminectomy and duroplasty (laminectomy + duroplasty group). Primary outcomes were MRI evidence of spinal cord decompression (increase in intradural space, cerebrospinal fluid around the injured cord) and spinal cord physiology (ISP, SCPP, sPRx). The laminectomy and laminectomy + duroplasty groups were well matched. Compared with the laminectomy group, the laminectomy + duroplasty group had greater increase in intradural space at the injury site and more effective decompression of the injured cord. In the laminectomy + duroplasty group, ISP was lower, SCPP higher and sPRx lower, i.e. improved vascular pressure reactivity, compared with the laminectomy group. Duroplasty caused Cerebrospinal fluid fistula that settled with lumbar drainage in one patient and pseudomeningocele that resolved in five patients. We conclude that, after TSCI, laminectomy + duroplasty improves spinal cord radiological and physiological parameters more effectively than laminectomy 1).
