The average age of spinal cord injured person is 43.Nearly half (47.6%) of all injuries occur between the ages of 16 and 30.Approximately 17,730 new injuries occur each year.

39.5% of spinal cord injured individuals are considered paraplegic and 59.9% quadriplegic.

Approximately 291,000 Americans are spinal cord injured.Who Do Spinal Cord Injuries Affect in the United States? The length of hospital stays is declining with the average stay in hospital acute care at 11 days – down from 24 in the 1970’s – and rehabilitation stays at 31 days – down from 98 days in the 1970’s. The average age at injury has moved from 29 years in the 1970’s to 43 years in 2018. Researchers have estimated that, as of 2019, 17,730 new SCI cases occur each year and between 249,000 and 363,000 people are currently living with SCI in the United States. Violence (primarily gunshot wounds) 13.5%.Spinal Cord InjuriesĪccording to the National Spinal Cord Injury Statistical Center at UAB, the distribution of the causes of SCI have changed drastically from 2015-2018/19. Tests of the predictive accuracy of the technique using dendrites of known total spine number suggest that estimates which deviate from true total spine numbers by less than 10% can be achieved.Think you know the facts about spinal cord injuries? Here is some information that may surprise you. The technique entails the following principal steps: a determination, for a given length of dendrite over which spines are to be enumerated, of the volume of the flanking zones in which spines are visible and can be counted a determination of the volume of the entire zone which encircles the dendritic shaft and which contains all spines, both visible and not visible and a proportional extrapolation from the number of visible spines to obtain an estimate of the true total spine number. In the present report, a geometrically based method is presented whereby total dendritic spine numbers can be estimated with reasonable accuracy, taking into account factors such as dendrite diameter and spine length. This seriously restricts the usefulness of comparisons of spine density between dendrites, or even between segments of the same dendrite. The magnitude of underrepresentation correlates positively with dendritic shaft diameter and negatively with spine length. Such counts, limited to only those spines which are visible, underrepresent the true total number of spines borne by the dendrites. These studies have, for the most part, involved the enumeration of only those spines which protrude from the opaque shafts of Golgi-impregnated dendrites into the clear zones flanking the dendrite. The functional significance of dendritic spines and their morphological sensitivity to a wide spectrum of experimental manipulations and pathological states have led to a number of studies in which counts of dendritic spine number have been carried out.
