This study analyzed the mortality in 1453 spinal cord injured patients admitted early after injury to a specialised Spinal Injuries Unit within a University teaching hospital over a 40-year period. The cohort comprised 55.3% patients with cervical lesions and 44.7% patients with thoracic/lumbar lesions. Those patients who died within 18 months of the spinal injury (132) were excluded from the final analysis. Standardised Mortality Ratios, survival rates and life expectancy ratios were calculated for specific ranges of current attained age and duration since injury with reference to level and degree of spinal cord injury. The projected mean life expectancy of spinal cord injured people compared to that of the whole population was then estimated to approach 70% of normal for individuals with complete tetraplegia and 84% of normal for complete paraplegia (Frankel grade A). Patients with an incomplete lesion and motor functional capabilities (Frankel grade D) are projected to have a life expectancy of at least 92% of the normal population.
本研究分析了40年间在一所大学教学医院的专门脊髓损伤病房早期收治的1453例脊髓损伤患者的死亡率。该队列包括55.3%的颈椎损伤患者和44.7%的胸/腰椎损伤患者。脊髓损伤后18个月内死亡的患者（132例）被排除在最终分析之外。根据脊髓损伤的水平和程度，计算了特定当前年龄范围和受伤后持续时间的标准化死亡率、生存率和预期寿命比。然后估计，与整个人口相比，脊髓损伤患者的预计平均预期寿命，对于完全性四肢瘫痪患者接近正常的70%，对于完全性截瘫患者（Frankel A级）接近正常的84%。不完全损伤且具有运动功能能力的患者（Frankel D级）预计预期寿命至少为正常人群的92%。
