Major Points and Findings:
- Objective: The primary goal of treatment in acute spinal cord injury (SCI) is to minimize secondary damage and promote neurological regeneration and functional recovery. The report critically evaluates the role of surgical interventions in achieving these objectives.
- Current Treatment: The standard care for acute SCI is medical therapy with steroids. However, the efficacy of this treatment has been questioned, leading to investigations into the role of surgical interventions.
- Surgical Decompression: Surgical decompression has been proposed as a potential treatment modality. The timing, role, and type of surgical decompression, as well as the optimal surgical intervention, are topics of debate in the context of acute SCI treatment.
- Animal Models: Animal models are crucial for evaluating potential treatment modalities before translating them into human trials.
- Acute SCI Statistics: Acute SCI is a significant cause of morbidity and mortality, with an annual incidence of 10,000 to 12,000 cases in the United States. The global prevalence is nearing 2 million, with the U.S. spending over $4 billion annually on medical treatment for acute SCI.
- Surgical Benefits: Surgery can offer better neurological recovery and facilitate early rehabilitation by decompressing the spinal cord and nerve roots. It can also prevent further neurological deterioration and secondary damage post-SCI.
- Study Methodology: The authors conducted an evidence-based review of clinical studies and experimental research in animal models from 1990 to 2013. The focus was on "acute spinal cord injury," "decompression," and "surgical intervention."
- Clinical Research Findings: Various studies were summarized, indicating mixed results on the benefits of surgical decompression. Some studies showed that early decompression resulted in reduced hospitalization stay, while others found no significant difference in functional grade improvement. The timing of surgery, type of injury, and surgical intervention varied across studies.
- Basic Research Findings: Animal studies were also summarized, with findings indicating that decompression's effectiveness might be inversely proportional to the duration of compression. Some studies showed improved recovery with early decompression, while others highlighted the benefits of specific surgical techniques.
- Secondary Injury Mechanisms: Acute SCI involves both primary mechanical and secondary cellular injuries. The primary trauma is irreversible and triggers a series of pathological and molecular changes.
