Density of myelinated axons according to type of spinal cord injury.

(A) Density in the gracile fasciculus (i) differences from control: dislocation –1, to +3 mm; contusion –3 to +5 mm; distraction none (ii) differences between contusion and dislocation: –3, +3 mm. (B) Density in the dorsal corticospinal tract: (i) differences from control: contusion –3 to +1 mm; dislocation –5, –1 to +1 mm; distraction: none; (ii) differences between dislocation and contusion: –1 mm. (C) Density in the lateral white matter: (i) differences from control: dislocation -3 to +3 mm; contusion –5 to +3 mm; distraction none; (ii) differences between dislocation and contusion: –1, 0 mm. (D) No differences were found between the three injury types in the ventral white matter. Data shown are means ± standard deviation (n = 10 in each group). Data were analyzed using two-way repeated-measures analysis of variance followed by Tukey’s honestly significant difference testing.
