摘要

目的:分析正常人群掌中尺侧CMAP的形态、振幅,分析正常尸体手小肌的解剖神经支配。设计:横断面研究。设置:门诊设置和亚历山德里亚大学的解剖部门。参与者:300名正常成年人(82名男性,218名女性)和30名正常成人尸体。主要观察指标:正常受试者正中神经和尺神经的运动传导研究。分别记录鱼际和鱼际下肌肉的CMAP,并分析其波形形状和振幅。解剖了正常尸体的鱼际和鱼际下肌的神经供应。记录神经主干(正中或尺侧)、分支数量、大小及进入肌肉的位置。结果:研究人群平均年龄为37.86±8.83岁(年龄范围19 ~ 69岁)。正中神经的平均振幅显著高于尺神经(分别为11.785±5.0、10.45±2.96,p=0.0001)。正中神经远端平均潜伏期显著高于尺神经(分别为3.38±0.41和2.698±0.40,p=0.0001)。正中神经CMAP多呈圆顶状而非双峰状,差异有统计学意义(p=0.0001),尺神经CMAP多呈双峰状而非圆顶状,差异有统计学意义(p=0.0001)。穹状CMAP组正中神经远端潜伏期明显长于双峰CMAP组(p=0.002)。同样,穹状CMAP患者的尺神经远端平均潜伏期明显长于双峰CMAP患者(p=0.0001)。在正中神经和尺神经上,穹状CMAP与双峰CMAP的振幅差异无统计学意义。解剖结果表明,90%的标本由正中神经支配,10%的标本由两种神经支配。指外展肌由尺神经深支支配90%由尺神经浅支支配10%在50%的标本中有正中神经和尺神经之间的连接。结论:正中神经CMAP多呈圆顶型,尺神经CMAP多呈双峰型。手部小肌肉神经支配模式的变化可能是一个可能的病因。

Analysis of Compound Muscle Action Potential of Median and Ulnar Nerves: Possible Anatomical Correlation
Objective: To analyze of shape, amplitude of CMAP of both median and ulnar in normal population and to analyze the anatomical innervations of small muscles of hand in normal cadavers. Design: Cross sectional study. Settings: outpatient settings and department of anatomy at Alexandria University. Participants: 300 normal adults (82 males and 218 females) and 30 normal adult cadavers. Main outcome measures: Motor conduction study of both median and ulnar nerves for the included normal subjects. Surface recording of CMAP from thenar and hypothenar muscles respectively with analysis of the shape of the waveform and amplitude. The nerve supply of both thenar and hypothenar muscles were dissected for the included normal cadavers. The main nerve trunk (median or ulnar), the number of branches, their sizes and their sites of entering into the muscles were recorded. Results: The mean age of the studied population was 37.86 ± 8.83 (age range 19-69). The mean amplitude of the median nerve was significantly higher than that of the ulnar nerve (11.785 ± 5.0, 10.45 ± 2.96 respectively, p=0.0001). The mean distal latency of median nerve was significantly higher than that of ulnar nerve (3.38 ± 0.41 and 2.698 ± 0.40 respectively, p=0.0001). The median nerve had mostly dome shaped CMAP rather than double peaked CMAP with significant difference (p=0.0001), while the shape of CMAP of the ulnar nerve was more frequently double peaked rather than dome shaped with significant difference (p=0.0001). The mean distal latency of the median nerve was significantly longer in those with dome shaped CMAP rather than those with double peak CMAP (p=0.002). Similarly, the mean distal latency of the ulnar nerve was significantly longer in those with dome shaped CMAP compared with those with double peak CMAP (p=0.0001). There were no statistical significant differences between the amplitude of dome shaped CMAP and the double peaked CMAP in either the median or the ulnar nerve. The anatomical results showed that abductor pollicis brevis supplied by the median nerve in 90% of specimens, and by both nerves in 10%. The abductor digiti minimi brevis supplied by the deep branch of the ulnar nerve in 90% and by superficial branch of the ulnar nerve in 10%. There was a connection between the median and ulnar nerves in 50% of specimens. Conclusion: The configuration of the CMAP of the median nerve is mostly dome, whereas that of the ulnar is mostly double peaked. Variability in the pattern of innervations of the small muscle of the hand could be a possible etiological factor.
