ABSTRACT
Forensic Medicine experts have to evaluate age in different medico legal situations, especially when the identity is not known, when the liability and punishment are related to the maturity. The study of epiphysial union of bones is considered a reasonable scientific and accepted method for estimation of age by the courts of law all over the world. The present study was carried out on 150 persons of age group between 17-21 years by using digital X-ray method in the Department of Forensic medicine and Toxicology at Govt. Medical College & New Civil Hospital, Surat.The present study possibly may generate the data giving shorter age intervals of fusion of centers of Ischial tuberosity (as compared to the standard text books or on the other end, may even positively reconfirm the evidential value of current data by using modern technique of digital X-ray). Anyhow, it will contribute to the better procurement and application of justice.

El objetivo de este estudio fue determinar la influencia de la extensibilidad isquiosural en la morfología sagital del raquis e inclinación pélvica en deportistas jóvenes. Métodos. Un total de 152 deportistas (media de edad: 16,22 +/- 0,80 años) participaron voluntariamente en este estudio. La morfología sagital de las curvas torácica y lumbar, así como la inclinación pélvica, fueron evaluadas con un Spinal Mouse al realizar los test sit-and-reach, toe-touch y McRae & Wright. La extensibilidad isquiosural fue determinada mediante el test de elevación de la pierna recta (EPR). En base al valor obtenido en el test EPR, la muestra fue dividida en tres grupos (Grupo A: EPR < 76, n=49; Grupo B, EPR entre 76-88, n=45; y Grupo C, EPR > 88, n=50). Resultados. Los deportistas con menor extensibilidad isquiosural adoptaron posturas de mayor cifosis torácica y una mayor retroversión pélvica en los test sit-and-reach y toe-touch. No obstante, no se encontraron diferencias significativas entre grupos en el test McRae & Wright. Además, la extensibilidad isquiosural no tuvo influencia alguna en la morfología sagital del raquis lumbar. Conclusiones. Una menor extensibilidad isquiosural está relacionada con una mayor cifosis torácica y una mayor retroversión pélvica cuando se realizan movimientos de flexión máxima del tronco con rodillas extendidas. La extensibilidad isquiosural no afecta a la disposición sagital del raquis lumbar en movimientos de flexión máxima del tronco.
The objective of this study was to determine the influence of hamstring extensibility in sagittal spinal curvatures and pelvic inclination on young athletes. Methods: A hundred and fifty-two young athletes (mean age: 16.22 +/- 0.80 years) were recruited. Thoracic and lumbar curvatures and pelvic inclination were evaluated with a Spinal Mouse system in the sit-and-reach test, toe-touch test and McRae & Wright test. Hamstring muscle extensibility was determined by passive straight leg raise test (PSLR). The sample was divided into three groups with regard to straight leg raise angle (Group A: PSLR < 76, n=49; Group B, PSLR between 76-88, n=45; and Group C, PSLR > 88, n=50). Results. Athletes with lower extensibility presented higher thoracic angle and a more posterior pelvic tilt in the sit-and-reach and toe-touch tests. However, no significant differences were found between groups when maximal trunk flexion with knees flexed was performed (McRae & Wright test). The lumbar curve was not affected by hamstring extensibility in any position. Conclusions: Lower hamstring extensibility is related to increased thoracic curve and more posterior pelvic tilt when maximal trunk flexion with knees extended is performed. Hamstring extensibility has not any influence in sagittal lumbar morphology when trunk flexion is performed.
