摘　　要：目的应用高频超声测量健康志愿者的拇指末节指骨及拇趾末节趾骨基底横径及前后径。方法对120例健康志愿者，采用高频超声对拇指末节指骨基底及同侧拇趾末节趾骨基底横径及前后径进行测量，对测量数据进行统计学分析。结果拇指末节指骨基底及拇趾末节趾骨基底高频超声特征：两组拇指及拇趾末节指骨基底横切面上高频超声表现为强回声带，边界清楚，与之邻近的筋膜、肌腱组织表现为低回声区。男性组拇指末节指骨基底的前后径为（8．07±0．67）mm，拇趾末节趾骨基底的前后径为（8．34±1．02）mm（t=1．73，P=0．86）；拇指末节指骨基底的横径为（11．61±0．89）mm，拇趾末节趾骨基底的横径为（14．25±0．84）mn]（t：16．77，P：0．01）。女性组拇指末节指骨基底的前后径为（7．52±0．62）mm，拇趾末节趾骨基底的前后径为（7．72±0．67）mm（t=1．72，P=0．14）；拇指末节指骨基底的横径为（10．94±0．97）mm，拇趾末节趾骨基底的横径为（13．51±0．75）mm（t=16．21，P=0．00）。结论通过健康志愿者拇指及拇趾末节指骨基底的前后径和横径高频超声测量正常值，对带末节趾骨拇甲瓣修复拇指Ⅱ度缺损手术时切除趾末节趾骨的方法具有重要指导价值。Objective To measure the normal sagittal and coronal diameters of thumb and great toe distal phalanx bottom by ultrasonography. Methods One hundred and twenty volunteers＇ sagittal and coronal diameters of thumb and great toe distal phalanx bottom were measured by ultrasonography. The measurements was analysed by the statistical method. Results The thumb and great toe distal phalanx bottom showed hyperechoic zone,clear boundary with the adjacent fascia and tendon tissue showed low echo area at cross section by high frequency ultrasound. The sagittal diameters of thumb distal phalanx bottom was （8.07± 0.67）mm in men, while that of great toe distal phalanx bottom was （8.34 ± 1.02）mm（ t = 1.73, P = 0.86）. The coronal diameters of thumb distal phalanx bottom was （11.61± 0.89）mm in men, while that of great toe distal phalanx bottom was （14.25 ± 0.84）mm（ t = 16.77, P = 0.00）. The sagittal diameters of thumb distal phalanx bottom was （7.52± 0.62）mm in women, while that of great toe distal phalanx bottom was （7.72± 0.67） mm（ t = 1.72, P = 0.14）. The coronal diameters of thumb distal phalanx bottom was （10.94± 0.97）mm in women, while that of great toe distal phalanx bottom was （13.51 ± 0.75）mm （ t = 16.21, P = 0.00）. Conclusions The normal sagittal and coronal diameters of thumb and great toe distal phalanx bottom measured by the ultrasonography can guide the operation of wrap-around flap of a great toe with phalanx ungual for thumb Ⅱ degree defect reconstruction.
