Epidemiological study of traumatic spinal cord injuries: experience from a specialized spine center in Iran

Study design: A cross-sectional study. Objectives: This study was performed for epidemiological assessment of Iranian Traumatic Spinal Cord Injuries (TSCI), referred to a specialized spine center. Setting: Patient recruitment and evaluations were conducted at the Brain and Spinal Injury Research Center, Tehran, Iran. Methods: This study was performed from September 2011 to March 2015 on 1137 consecutive TSCIs. History, clinicoradiological findings as well as chronic complications and social integration were recorded. The capture-recapture method was used to calculate a rough estimation of TSCI prevalence in Tehran Province. Results: Our report includes 1137 cases with a mean age of 29.1 years (s.d.=11.2 year)-79.2% of them being male (M/F=3.8/1). Rough estimation of TSCI prevalence in Tehran province was 2.36 per 10 000 population. Regarding etiology, 61.8% were due to motor vehicle accident (MVA), followed by falling 24.5%, heavy drop 5.2%, violence 3.8%, sport 2.8% and others causes 1.9%. Regarding injury level, 31.5% were cervical, 57.9% thoracic and 10.6% lumbar. Complete lesions were 53.5% of patients and 46.5% were incomplete. Most common neurological type was T1-S5 (American Spinal Injury Association Impairment Scale: A, B, C, 61.7%). Most common complications included urinary tract infection followed by pressure sore (grade III and IV, 37.5%), autonomic dysreflexia (37%) and neuropathic pain (31.2%). Substance abuse was observed in 8.8% of cases. Overall, similar to 25% in our cases were employed after TSCI. Secondary divorce was also much more frequent than normal matched controls. Conclusion: MVA was the most common cause for TSCI. The elderly subjects were less frequent among our patients than more developed countries. The high rate of unemployment and divorce in our cases deserves special consideration.
