ABSTRACT
OBJECTIVE@#To discuss bone development trend in the knee joint of Tibetan teenagers in Sichuan province and to effectively update the database for estimating the living age of Tibetan teenagers in terms of bone age of the knee joint.@*METHODS@#Radiographs including epiphysis of distal femur, proximal tibia and proximal fibula were taken from 483 Tibetan male and female teenagers aged from 14 to 19 years old in Aba prefecture of Sichuan province in order to observe epiphyseal growth situation. The descriptive data of the epiphyseal closure ages of these teenagers' knee joints were statistically analyzed by SPSS 16.0 software.@*RESULTS@#The distal femur epiphyseal closure occurred earliest, while the proximal fibula epiphyseal closure occurred latest. The epiphyseal growth of knee joints of females occurred about one year earlier than that of males.@*CONCLUSION@#The forensic information and data related to Tibetan teenagers' bone age identification should be updated regularly. These results provide potential value for the practice of forensic medicine, anthropology and clinical medicine.

Normal values of the tibial slope are necessary for realignment of displaced fractures of the tibia crest, repair of cruciate ligaments and correction of knee deformities. True lateral radiographs of normal knees were obtained in 119 males and 93 female Nigerian subjects. The tibial slope was then measured according to the anterior tibial cortex method. Mean angle in sampled subjects was 12.3 +/- 4.90 (range: 0-240). Sex differences were statistically insignificant (p>0.05). This study provides reference values of tibial slope among indigenous adult Nigerians. It also highlights on the clinical relevance of the angle and the need to establish normal ranges in other African populations.
Los valores normales de la inclinación tibial son necesarios para conocer el reajuste de las fracturas desplazadas de la cresta tibial, reparación de los ligamentos cruzados y corrección de deformidades de la rodilla. Radiografías laterales de rodillas normales fueron obtenidas de 119 hombres y 93 mujeres de Nigeria. La inclinación tibial fue medida de acuerdo al método de la corteza tibial anterior. La media del ángulo de la muestra de los sujetos estudiados fue 12,3 +/- 4,90 (rango: 0-240). Diferencias por sexo fueron estadísticamente significativas (p> 0,05). Este estudio proporciona valores de referencia de pendiente tibial en adultos indígenas nigerianos. También se destaca la relevancia clínica del ángulo y la necesidad de establecer los rangos normales en otras poblaciones africanas.
