Inter- and Intrarater Reliability of the Thumb Grasp and Pinch Assessment for Children Following Index Pollicization for Congenital Thumb Hypoplasia

Outcome After Pollicization for Congenital Thumb Deficiency: A Cohort Study of Cases in a Single Unit, 1987 to 2016

“…46 Researchers have recently developed video-based thumb hypoplasia evaluations that might be recommended for use in future studies, of which the Thumb Grasp and Pinch has the best documentation. 44,45,48 Also, in the hands with the most severe anomalies and the least favorable outcomes, we judged the index fingers preoperatively as suitable for pollicization. Spontaneous use of the index finger and satisfactory range of motion in the index PIP joint, combined with satisfactory positions and functions of the wrist and the elbow, have been necessary for meeting the indication for pollicization in our unit.…”

Evaluación funcional posterior a la pulgarización en hipoplasia de pulgar mediante uso de T-GAP score

“…El objetivo de la pulgarización es permitir que los niños puedan tener una variedad más amplia de patrones de agarre y pellizco y en última instancia, para mejorar el uso de la mano en el día a día de sus actividades. 4 Puntos técnicos de qué estructura en índice se convierte en qué en el neopulgar.…”

“…3 El pulgar contribuye hasta 40% de la función de la mano. 4 El índice es más largo que el pulgar, pero no tiene la versatilidad de su musculatura, particularmente los intrínsecos. Además, la articulación carpometacarpiana del pulgar es única en su arquitectura y permite un movimiento estable de 360 o para dar el movimiento de oposición único al pulgar humano.…”

Pollicization of the Index Finger in the Treatment of Thumb Hypoplasia

“…10 Validated tests that assess the grasp and pinch of the thumb will allow us to evaluate the functional impact of this technique in the future. 11,12 According to the literature, grip strength is 63% to 75% of the contralateral side, while pinch strength reaches up to 56% to 65% depending on the previous function of the index finger and the technique used. [13][14][15][16] One of the most important factors associated to a successful transposition is the quality of the index finger to be transposed.…”

“…Functional outcomes of a pollicized hand have been difficult to measure because of the lack of consensus of a standardized test 10. Validated tests that assess the grasp and pinch of the thumb will allow us to evaluate the functional impact of this technique in the future 11,12. According to the literature, grip strength is 63% to 75% of the contralateral side, while pinch strength reaches up to 56% to 65% depending on the previous function of the index finger and the technique used 13–16…”
