Sensation, strength, dexterity, length, and range of motion were evaluated after index finger pollicization in 10 patients (14 hands). Diagnoses included congenital absence of the thumb (10 hands) and hypoplasia (4 hands). Average age at operation was 7 years, and follow-up averaged 9 years. Patients with unilateral pollicization averaged 67% grip strength, 60% lateral pinch, 56% palmar pinch, and 39% three-point pinch as compared with the normal contralateral hand. Manual dexterity averaged 70% efficiency as compared with normal standards defined according to age and sex. However, 55% of the patients, when stressed, used side-to-side pinch. It was noted that in those patients who used side-to-side pinch performance averaged 54% of normal standards, compared with 93% in patients who used tip-to-tip pinch for prehension.
对10例患者（14只手）的示指拇化术后的感觉、力量、灵活性、长度及活动范围进行了评估。诊断包括先天性拇指缺如（10只手）和发育不全（4只手）。手术平均年龄为7岁，平均随访9年。与对侧正常手相比，单侧拇化患者的握力平均为67%，侧捏力为60%，掌捏力为56%，三点捏力为39%。与根据年龄和性别定义的正常标准相比，手部灵活性平均效率为70%。然而，55%的患者在用力时采用侧向捏。值得注意的是，在那些采用侧向捏的患者中，其操作表现平均为正常标准的54%，而采用指尖对指尖抓握的患者为93%。
