ABSTRACT
The aim of this study was to measure the version of femoral neck on dried Thai human femora. The version of femoral neck varies widely. It is important to know the version of femoral neck in a particular population to undertake successful femoral neck reconstructive surgery. Paired 216 dried femora of adult Thais from the bone collection maintained in the Department of Anatomy at the Faculty of Medicine, Khon Kaen University, Thailand, were used to measure the version of femoral neck. The mean+SD femoral anteversion (FNA) was 16.21+5.24 degrees. The 95% confidence interval of FNA was from 15.48 to 16.94 degrees. The 95% confidence intervals of male and female average FNA were 14.75 to 16.90 and 15.59 to 17.59 degrees respectively. There was no significance difference of the FNA between males and females in both anteversion and retroversion groups. The average male FNA showed no statistical difference to average female anteversion. The 95% confidence intervals of males and females average retroversion were -8.22 to -4.80 and -7.71 to -4.47 degrees respectively. The average male retroversion showed no statistical difference to average female retroversion. The overall 95% confidence interval of femoral neck anteversion and retroversion were 15.48 to 16.94 degrees and -7.33 to -5.27 with no significant difference between males and females. These degrees of FNA must be considered when the femoral neck reconstructive surgery is planned.
El objetivo fue medir el cuello femoral en fémures humanos de tailandeses adultos. La versión del cuello femoral es muy variable. Es importante conocer la versión de cuello femoral en una población en particular para llevar a cabo con éxito una cirugía reconstructiva. Se utilizaron 216 fémures secos de adultos tailandeses obtenidos de la colección del Departamento de Anatomía de la Facultad de Medicina de la Universidad de Khon Kaen, Tailandia. La anteversión femoral (AFM) media+DE fue de 16,21±5,24. El intervalo de confianza del 95% de la AFM fue entre 15,48 a 16,94. El promedio de intervalos de confianza del 95% en hombres y mujeres fue desde 14,75 a 16,90 y 15,59 a 17,59, respectivamente. No hubo diferencia significativa entre hombres y mujeres en ambos grupos de anteversión y retroversión. La AFM promedio en hombres no mostró diferencia significativa con la anteversión media de las mujeres. Se observó un promedio de -8,22 a -4,80 y -7,71 a -4,47 en el 95% de los intervalos de confianza entre hombres y mujeres, respectivamente. La retroversión promedio en hombres no mostró ninguna diferencia significativa con la retroversión media en las mujeres. Estos grados de AFM deben ser considerados en la planificación de una cirugía reconstructiva del cuello femoral.

In order to develop new surgical techniques on, and fixation devices for, carpal scaphoid fractures in Thais, the authors determined the mean and standard deviation of the length, width and thickness of 141 carpal scaphoid bones on 93 left and 48 right wrists from the skeletons of 99 Thai males and 42 Thai females. The deceased averaged 60 years (range, 22 to 89). The scaphoid length averaged 25.59 mm; the dorsal width at the distal, middle and proximal poles averaged 14.89, 10.23 and 7.08 mm, respectively; the palmar width at the distal, middle and proximal poles averaged 14.22, 9.81 and 7.44 mm, respectively; and the thickness at the distal, middle and proximal poles averaged 9.77, 10.96 and 9.19 mm, respectively. The authors found no signficant difference (p = 0.96) in the length and width of the Thai carpal scaphoid bone between the left and right wrist. The widths of the dorsal and palmar sides at the distal end were wider than the proximal end and tapered from the distal to the proximal pole. The thicknesses were constant throughout the length of the bone, ranging between 9 and 11 mm.
