In 19 carpal tunnel syndrome (CTS) patients and 4 control subjects a catheter was introduced into the carpal tunnel and slowly retracted in 5 mm steps. Pressure was measured with the continuous infusion technique. In the same group of patients and controls, median nerve antidromic sensory action potential (aSAP) was detected intraoperatively stimulating proximally (S1), in the center (S2), and distally (S3) to the carpal tunnel and recording from the third finger (R). Sensory conduction velocity (SCV) and aSAP amplitude were considered in S1-S2, S2-S3 and S3-R segments. The intracarpal tunnel pressure was significantly higher in CTS patients than in controls, with the highest values located between 25 and 35 mm distal to the proximal border of the flexor retinaculum. SCV and aSAP amplitude were also decreased most often in the distal part (S2-S3) of the carpal tunnel.
在19名腕管综合征(CTS)患者和4名对照受试者中,将一根导管插入腕管,并以5毫米的步长缓慢回拉。采用连续输注技术测量压力。在同一组患者和对照中,术中在腕管近端(S1)、中部(S2)和远端(S3)进行刺激,并从第三指进行记录(R),检测正中神经逆行感觉动作电位(aSAP)。在S1-S2、S2-S3和S3-R节段中考虑感觉传导速度(SCV)和aSAP振幅。CTS患者的腕管内压力明显高于对照组,最高值位于屈肌支持带近端边界远端25至35毫米之间。SCV和aSAP振幅在腕管远端部分(S2-S3)也最常降低。
