To evaluate the objective features and subjective aesthetic outcome of pollicized digits compared with normal thumbs.
Thirty-one pollicized digits in 26 patients were evaluated at an average 41 months after surgery. The length, girth, and nail width were measured and compared with previously reported data for normal thumbs. A surgeon, therapist, and caregiver completed Visual Analog Scales (VAS) to subjectively assess the aesthetic outcome; they also provided the principal reasons for their assessment of the altered appearance compared with normal thumbs. All data were statistically analyzed.
The average length of the pollicized digit relative to the long finger proximal phalanx was 90% (+/-26%), compared with an age-matched normal average of 71%. The girth of the pollicized digit relative to the long finger was 92% (+/-8%), compared with an age-matched normal thumb average of 132%. The nail width of the pollicized digit relative to the nail width of the long finger was 96% (+/-9%), compared with an age-matched normal thumb average of 104%. The VAS scores averaged 7.3 for the caregiver, 6 for the therapist, and 6.4 for the surgeon. The most frequently cited (altered) features were narrow girth, angulation, and excess length of the pollicized digit.
Pollicized digits are longer and have reduced girth and nail width compared with age-matched normal thumbs. The most significantly abnormal features are decreased girth, excess length, and angulation.
评估与正常拇指相比，拇指化手指的客观特征和主观美学效果。
对26例患者的31根拇指化手指在术后平均41个月时进行评估。测量其长度、周长和指甲宽度，并与此前报道的正常拇指数据进行比较。一名外科医生、一名治疗师和一名护理人员完成视觉模拟量表（VAS）以主观评估美学效果；他们还给出了与正常拇指相比对手指外观改变进行评估的主要原因。所有数据均进行统计学分析。
拇指化手指相对于示指近节指骨的平均长度为90%（±26%），而年龄匹配的正常拇指平均长度为71%。拇指化手指相对于示指的周长为92%（±8%），而年龄匹配的正常拇指平均周长为132%。拇指化手指相对于示指指甲宽度的指甲宽度为96%（±9%），而年龄匹配的正常拇指平均指甲宽度为104%。护理人员的VAS评分平均为7.3分，治疗师为6分，外科医生为6.4分。最常被提及的（改变的）特征是拇指化手指周长变窄、成角和长度过长。
与年龄匹配的正常拇指相比，拇指化手指更长，周长和指甲宽度减小。最明显异常的特征是周长减小、长度过长和成角。
