Objective To study the fundamental anatomy of transferring T9-12 nerve roots to L2-4 nerve root for the quadriceps function recovery inside the spinal canal of paraplegia. Methods Thoracic and lumbar spinal canal and spinal dura mater of 5 adult cadavers (male 2 and female 3) were opened and explored. Investigated including: the position which T9 -L4 nerve root generated from spinal cord; the relation between the position which T9-L4 nerve root generated from spinal cord and T12 vertebrae and L1 vertebrae;The length beginning part of T9-L4 nerve root inside the spinal canal. The diameter of T9-L4 nerve root. The distance between the T9-L4 nerve root separately. The distance between the position which T9-12 nerve root separately generated from dura mater and the middle of L2 vertebrae. Results T9 nerve root generated from the middle part of T9 vertebrae; L4 nerve root generates from middle part of L2 vertebrae. The average length of T9-L4 nerve root inside the spinal canal separately was 16. 12, 22. 97, 30. 43, 43.47, 56. 02, 70. 03,88. 70 and 113.65 mm. The average diameter of T9 -L4 nerve root separately was 2. 45, 2. 04, 1.96, 2. 18,2. 32, 2. 56, 3. 10 and 3.26 mm. The average distance between the beginning part of T9-L4 nerve root separately was 22. 87, 25.08, 28.47, 27.38, 29.78, 31.93 and 31.00 mm. The average distance between the position which T9-12 nerve root separately generated from dura mater and the middle of L2 vertebrae was 118.69, 95.82, 70.74, and 42.27 mm. Conclusions T9-12 nerve root can be used as donor nerve for repair L2-4 nerve root. The level of L2 vertebrae can be anastomose site of the recipient nerve.
