The spinal cord injury problem--a review.

Area of Science:

• Neuroscience
• Trauma Research
• Clinical Trials

Background:

• Spinal cord injury (SCI) presents significant personal and societal costs.
• Experimental studies indicate that the spinal cord's response to injury contributes to neurological deficits.
• Previous clinical treatments have not shown significant improvements in neurological outcomes.

Purpose of the Study:

• To investigate the hypothesis that the secondary injury response exacerbates neurological deficits after spinal cord injury.
• To evaluate the effectiveness of interventions targeting the secondary injury response.

Main Methods:

• Review of experimental studies defining posttraumatic pathological and biochemical changes in SCI.
• Analysis of clinical series with varied treatment regimens.
• Examination of a randomized clinical trial comparing high-dose versus low-dose steroid treatment for SCI.

Main Results:

• Experimental data supports the hypothesis of a secondary injury response in SCI.
• Clinical trials, including a steroid treatment trial, have not demonstrated significant improvements in neurological outcomes.
• Lack of therapeutic effectiveness in current treatments underscores the need for further research.

Conclusions:

• The secondary injury hypothesis warrants continued investigation due to its potential to explain a portion of neurological loss.
• Further experimental studies and randomized clinical trials are essential for advancing SCI treatment.
• Controlling the secondary injury response could have broader implications for other central nervous system injuries.
