RESUMO
OBJECTIVES@#To analyze the characteristics and mechanisms of pelvic fractures in the cases of road traffic accident deaths.@*METHODS@#Total 65 cases of road traffic accident deaths with pelvic fracture were collected, and the sites, characteristics and injury mechanisms of pelvic fracture were statistically analyzed.@*RESULTS@#Among the 65 cases of pelvic fracture, 38 cases of dislocation of sacroiliac joint were found, and most combined with pubis symphysis separation or fracture of pubis. In the fractures of pubis, ischium and acetabulum, linear fractures were most common, while comminuted fractures were most common in sacrum and coccyx fractures. There were 54 cases combined with pelvic soft tissue injury, and 8 cases with pelvic organ injury and 44 cases with abdominal organ injury. In the types of pelvic ring injury, 32 cases were separation, 49.32%, followed by compression, 26.15% and only one case was verticality, 1.54%.@*CONCLUSIONS@#Detailed and comprehensive examination of the body and determination of the pelvic fracture type contribute to analyze the mechanisms of injury.

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.
