Clinodactilia postraumática del meñique en el pelotari manista / Post-traumatic clinodactyly of the little finger in Basque hand-pelota players

OBJETIVO: 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. MATERIAL Y MÉTODOS: 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. RESULTADOS: 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). DISCUSIÓN: 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

OBJECTIVE: 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. MATERIAL AND METHODS: 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. RESULTS: 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). DISCUSSION: 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

[A case of idiopathic retropneumoperitoneum, pneumoperitoneum, pneumomediastinum and subcutaneous emphysema]. / A propósito de un caso de retroneumoperitoneo, neumoperitoneo, neumomediastino y enfisema subcutáneo idiopáticos.

We present a case of retropneumoperitoneum , pneumoperitoneum , pneumomediastinum and subcutaneous emphysema in a caquectic 17 years old young man with an important depressive disorder . Several possible etiopathogenic factors are discussed, as well as the pathways of transmission of the pulmonary , mediastinic and abdominal gas.
