Morphological study of the pelvis and vertebral column in university dance major students / Estudio morfológico de la pelvis y la columna vertebral en estudiantes universitarios de danza

SUMMARY: The purpose of this study was to investigate the pelvis and spine of university dance major students. The spine and pelvic morphology were measured in 32 students (eight ballet, eight Korean dance, and eight modern dance) and eight general studies students. using dual energy X-ray absorptiometry and Formetric III 4D. First, as a result of measuring the front and rear tilt, a back tilt of the torso was found in all groups. Second, measurement of the left and right tilt of the spine showed a tilt to the right, and the angle and distance of the tilt were 1.25 ? 1.16 ? and 10.5 ? 9.3 mm, respectively in the ballet major group. Third, the kyphosis angle was the highest in the Korean dance students, exceeding the normal range (ballet: 46 ?, Korean dance: 54 ?, modern dance: 47 ?, general department: 49?). Although, there was no significant difference among the groups, but the spine and pelvic morphology were measured in different forms (shapes) according to the majors. Therefore, according to the major, the movements used to affect the shape of the spine and the pelvis are considered to change. This suggests that follow-up studies are needed. If the displacement is severe due to the movement, pain may occur and it is necessary to study how to identify the pain area when the pain occurs.

RESUMEN: El propósito de este estudio fue investigar la pelvis y la columna vertebral de estudiantes universitarios de danza. Se realizaron mediciones morfológicas de la columna y la pelvis en 32 estudiantes (ocho de ballet, ocho de danza coreana y ocho de danza moderna) y ocho estudiantes de estudios generales. utilizando absorciometría de rayos X de energía dual y formétrico ? 4D. Primero, como resultado de medir la inclinación delantera y trasera, se encontró una inclinación del torso hacia atrás en todos los grupos. En segundo lugar, la medición de la inclinación izquierda y derecha de la columna mostró una inclinación hacia la derecha, y el ángulo y la distancia de la inclinación fueron 1,25 ? 1,16 ? y 10,5 ? 9,3 mm, respectivamente, en el grupo principal de ballet. En tercer lugar, el ángulo de cifosis fue el más alto en los estudiantes de danza coreana, excediendo el rango normal (ballet: 46 ?, danza coreana: 54 ?, danza moderna: 47 ?, departamento general: 49 ?). Aunque no hubo diferencia significativa entre los grupos, la morfología de la columna y la pelvis se midió en diferentes formas (formas) según las carreras. Por lo tanto, según la especialidad, se considera que cambian los movimientos utilizados afectando la forma de la columna y la pelvis. Esto sugiere que se requieren estudios de seguimiento. Si el desplazamiento es severo debido al movimiento, este puede generar dolor y es necesario estudiar cómo identificar el área de dolor cuando ocurre.

Postural Reduction in Compression Fracture of Spines

121 patients with cervical(45 patients), thoracolumbar(76 patients) compression or mild burst fractures from January 1984 to December 1994 were studied:98 patients were treated postural reduction with hyperextension posture and 23 patients were with postural reduction and surgical methods. We compared the initial and post-reduction compression height ratio, wedge angle and kyphosis angle of compression fractures. The results were not only expansion of a compressed vertebral body but also successful fusion. The neurological recovery status according to Frankel classification was also improved after postural reduction. Most of the compression fractures or stable burst fractures of the cervical, thoracolumbar spines can be restored by the postural reduction.

Postural Reduction for the Compression Fracture of the Thoracolumbar Spines

Postural reduction was performed in 20 cases of the closed thoracolumbar compression fracture using a soft pillow from January 1982 to June 1985. The results were summarized as following: 1) The compression fracture or mild burst fracture of the thoracolumbar spines can be restored by the postural reduction in hyperextension position using a soft pillow under the back of thoracolumbar junction. 2) The postural reduction resulted in not only expansion of a compressed vertebral body but also successful fusion. 3) It was most satisfactory when the postural reduction was performed as early as possible, at least within 1 week after injury. 4) The postural reduction is considered a simple and convenient treatment of the thoracolumbar compression fracture.
