摘要
目的观测腕管内容物并描述其相互间关系,为临床手外科学和显微外科学中的应用提供参考。方法采用游标卡尺对22具本成人尸体(男16具,女6具),44侧标本成人尸体标本腕管内容物测量,腕管解剖学观察、腕管内容物、腕横韧带的厚度测量等。结果腕管为纤维性骨管,略呈扁圆柱形,男性:狭窄部内外径(25.0±2.6)mm,前后径(10.2±1.l)mm;女性:狭窄部内外径(17.0±2.5)mm,前后(10.4±1.5)mm。腕横韧带男性:长(25.5±4.7)mm,宽(22.1±2.2)mm,厚2.3 mm,下界距腕远纹(28.4±2.6)mm;女性:长(22.7±3.3)mm,宽(20.1±2.5)mm,厚3.1 mm,下界距腕远纹(27.5±2.1)mm。腕管的断面,男性第1断面:(189.7±17.5)mm2,第2断面:(182.1±13.7)mm2,第3断面:(223.4±29.8)mm2;女性第1断面:(172.4±15.2)mm2,第2断面:(153.1±17.3)mm2,第3断面:(178.1±11.6)mm2。结论男性腕管宽短,女性腕管狭长,腕横韧带上半部薄,下半部厚,坚韧而缺乏弹性,女性腕管比男性狭窄,可能是好发疾病的原因之一。
Objective To observe the carpal tunnel contents and describe their relationship. Methods Stainless steel vernier caliper was used to measure carpal tunnel contents, carpal canal morphology, carpal tunnel contents, the transverse carpal ligament thickness of 22 cases （ male 16, female 6 ）, 44 specimens of adult cadaverie. Results Carpal tunnel was the fibrous tube, which was slightly flat, cylindrical. Male ： internal and external diameter of Stenosis was （ 25 ± 2.6 ） ram, anteroposterior diameter was （ 10.2 ± 1.1） mm. Female ： internal and external diameter of stenosis was （ 17 ± 2.5 ） ram, anteroposterior diameter was （ 10.4 ± 1.5 ） mm. The transverse carpal ligament of male ： （ 25.5 ± 4.7 ） mm long, （ 22.1 ± 2.2） mm wide, 2.3 mm thick, the lower bound from the distal wrist crease was （ 28.4 ± 2.6） mm. The first carpal tunnel section of male was （189.7 ± 17.5 ）mm2, the second section was （182.1 ± 13.7 ） mm2, the third section was （223.4 ±29.8） mm2. The first section of female was （ 172.4 ± 15.2） mm2, the second section was （ 153.1 ± 17.3） mm2, the third section was （ 178.1 ± 11.6）mm2. Conclusion The carpal tunnel of male was wide and short, the carpal tunnel of female was narrow, the top half of transverse carpal ligament was thin, lower half was thick, tough and inelastic. Female carpal tunnel is the narrower than men, which was the cause of diseases.
