Summary: | The aim of this study is to measure the DIP joint angle of the little finger and presence of degenerative changes in the DIP joint in Basque hand-pelota players and compare it with the general Spanish population.
Cross-sectional study. We studied both hands of 40 male Basque pelota players (pelotaris) and 20 male controls. The assessment protocol consisted of a questionnaire, physical examination and bilateral plain radiographs. Distal interphalangeal (DIP) joint angle was measured on plain radiographs in both hands.
The average DIP joint angle of the little finger in the control group was 2.6° in the dominant hand and 2.9° in the other hand. In the pelota players group we obtained a DIP angle of 6.8° in the dominant hand and 10.9° in the non-dominant hand. The DIP angle was significantly higher in the non-dominant hand (p=.002) in the pelota player group. Non-significant differences were obtained between both hands in the control group (p=.572). Significant differences were obtained in both player and control groups in the dominant hand (p=.001) and in the non-dominant hand (p=.001). Pelota players have a higher DIP angle in the little fingers than the control group. No differences were found in the pelota player group according to their position on the court (p=.742 forward, p=.747 defender) or sport level (p=.345 amateur, p=.346 professional).
Basque hand-pelota produces post-traumatic acquired clinodactyly of the little finger. The non-dominant hand has a higher DIP joint angle. Clinodactyly poses no functional problems.
Cuantificar la desviación angular de la articulación interfalángica distal (IFD) del 5.° dedo y la presencia de cambios degenerativos en IFD en jugadores de pelota y compararlos con una población española.
Estudio de casos y controles de una población de 40 pelotaris manomanistas federados y de un grupo control formado por 20 varones no practicantes de pelota. Se calcularon el ángulo IFD y la presencia de cambios degenerativos en la articulación.
El ángulo IFD medio del 5.° dedo en el grupo control fue de 2,6° en la mano dominante y de 2,9° en mano no dominante. Grupo de pelotaris: ángulo IFD de 6,8° en mano dominante y 10,9° en la no dominante. El ángulo IFD fue significativamente mayor en la mano no dominante (p=0,002) en el grupo de pelotaris. No se encontraron diferencias significativas entre ambas manos en el grupo control (p=0,572). Se hallaron diferencias estadísticamente significativas tanto para la mano dominante (p=0,001) como para la no dominante (p=0,001) al comparar grupo control con pelotaris. Los pelotaris tienen un ángulo IFD superior a los controles en ambas manos. No se encontraron diferencias estadísticamente significativas en grupo pelotari según la posición en la cancha (p=0,742 delantero, p=0,747 zaguero) ni por categorías (p=0,345 aficionado, p=0,346 profesional).
La práctica de pelota a mano se asocia a la presencia de una clinodactilia postraumática de la falange distal del 5.° dedo. La mano no dominante presenta unos ángulos mayores en IFD. La presencia de clinodactilia no genera limitación funcional. |
