ABSTRACT
The purpose of this study was to examine the plain anteroposterior radiographs of the hands in Turkish subjects in order to determine the prevalence of sesamoid bones and their distribution. A total of 923 hand radiographs from 459 men and 464 women with a mean age of 43.76±14.8 years (range, 18-85 years) were examined. Two sesamoid bones (ulnar and radial) were always present at the metacarpophalangeal (MCP) joint of the thumb (100 percent). One sesamoid bone in the thumb interphalangeal (IP) joint was observed in 21.3 percent of the cases. The prevalence of sesamoid bone of the index and little MCP joint were 36.6 percent and 53.2 percent respectively. Sesamoid bones palmar to the MCP joints of the middle finger and ring finger were rare; the incidence for these locations being 1.3 percent (12 hands) and 0.9 percent (8 hands), respectively. There were no significant differences between left and right hand digits. The distribution of sesamoid bones in different locations between male and female subjects were statistically similar in 1st IP joint (p=0.530), 4th MCP (p=0.631), 5th MCP (p=0.067) joints. However, the sesamoid bones in 2nd MCP and 3rd MCP joints were statistically more frequent in female subjects (p=0.024 and p=0.018 respectively). The present study represents the first report on the prevalence and distribution of sesamoid bones in the hand in Turkish subjects. The prevalence of sesamoid bones in Turkish population is considerably different from the Africans and Europeans, but rather resembles Mediterranean and Arab populations...
RESUMEN
El objetivo de este estudio fue examinar radiografías anteroposteriores de manos en sujetos turcos para determinar la prevalencia y distribución de los huesos sesamoideos. Fueron examinadas 923 radiografías de mano, 459 hombres y 464 mujeres, con edad media de 43,76 ± 14,8 años (rango, 18-85 años). Dos huesos sesamoideos (ulnar y radial) estuvieron siempre presentes en la articulación metacarpofalángica (MCF) del primer dedo de la mano (100 por ciento). Un solo hueso sesamoideo en la articulación interfalángica (IP) del primer dedo de la mano se observó en el 21,3 por ciento de los casos. La prevalencia del hueso sesamoideo, índice y articulación MCP fueron fue de 36,6 por ciento y 53,2 por ciento respectivamente. Los huesos sesamoideos palmares a las articulaciones metacarpofalángica del dedo medio y dedo anular eran poco frecuentes, su incidencia fue 1,3 por ciento (12 manos) y 0,9 por ciento (8 manos), respectivamente. No hubo diferencias significativas entre los dígitos izquierdos o derechos. La distribución de los huesos sesamoideos en diferentes lugares entre los sujetos de ambos sexos fueron estadísticamente similares entre las articulaciones primera interfalángica (p = 0,530), cuarta MCP (p = 0,631) y quinta MCP (p = 0,067). Sin embargo, los huesos sesamoideos en las articulaciones segunda MCP y tercera MCP fueron estadísticamente más frecuentes en el sexo femenino (p = 0,024 y p = 0,018, respectivamente). El presente estudio representa el primer informe sobre la prevalencia y distribución de los huesos sesamoideos en la mano en sujetos turcos. La prevalencia de los huesos sesamoideos en la población turca es considerablemente diferente de los africanos y los europeos, pero se asemeja a las poblaciones mediterráneas y árabes...
