To explore the feasibility of single incision C7 nerve transfer surgery through the subarachnoid pathway on the healthy side through anatomical research.
Four fresh frozen cadaver specimens were used for the study. Observe and measure the length of C7 nerve root fibers. Divide the front root into 3 bundles and the rear root into 5 bundles.
The C7 nerve has a filamentous structure, arranged symmetrically on both sides, and the length of the root fibers gradually shortens from top to bottom. The length of the left anterior root decreased from (12.25 ± 0.68) mm to (9.75 ± 1.40) mm, the length of the right anterior root decreased from (12.95 ± 1.49) mm to (10.00 ± 2.00) mm, the length of the left posterior root decreased from (15.63 ± 1.55) mm to (12.38 ± 0.71) mm, and the length of the right posterior root decreased from (15.48 ± 1.37) mm to (12.30 ± 0.90) mm. The distance from the exit of the C7 nerve from the dura mater to the fusion site in 4 specimens was (10.98 ± 1.21) mm on the left and (10.98 ± 1.391) mm on the right. All four specimens have completed nerve bundle anastomosis.
From an anatomical perspective, it is feasible to anastomose the healthy side C7 nerve with the affected side root fibers in the dorsal bundle of the spinal cord after cutting off the dura mater.
通过解剖学研究探讨经健侧蛛网膜下腔途径进行单切口C7神经移位手术的可行性。
使用4例新鲜冷冻尸体标本进行研究。观察并测量C7神经根纤维长度。将前根分为3束，后根分为5束。
C7神经呈丝状结构，两侧对称排列，根纤维长度自上而下逐渐缩短。左侧前根长度从(12.25±0.68)mm降至(9.75±1.40)mm，右侧前根长度从(12.95±1.49)mm降至(10.00±2.00)mm，左侧后根长度从(15.63±1.55)mm降至(12.38±0.71)mm，右侧后根长度从(15.48±1.37)mm降至(12.30±0.90)mm。4例标本中C7神经从硬膜穿出至融合部位的距离左侧为(10.98±1.21)mm，右侧为(10.98±1.391)mm。4例标本均完成神经束吻合。
从解剖学角度看，切断硬膜后将健侧C7神经与脊髓背侧束的患侧根纤维进行吻合是可行的。
