| Abstract
|
| [Objective] To develop spinal orthopedic shelf for kyphosis and study its clinical mechanism.[Methods] 1) The spinal orthopedic shelf with supporting force and triple points pressing effect was developed on the theory of treating fracture by splint. 2) Twenty-seven cases with kyphosis due to ankylosing spondylitis were treated with spinal orthopedic shelf.Their height, the angle of kyphosis deformity, the distance between pubis and manubrium of sternum or xiphoid process were measured. 3) The orthopedic force and mechanism of the spinal orthopedic shelf were detected with piezoelectricity and biomechanics.[Results] The mean increase of patients’ height was 6.1 cm, ranged from 2 to 16 cm. The distance of pubis and manubrium of sternum enlarged for 5.1 cm and of xiphoid process 4.3 cm. X-ray showed that the angle of kyphosis deformity was improved 12.1°.The orthopedic effect was accomplished by traction and pressing force together. The tractive force and pressing force were 4.7 kg and 18 kg respectively. And traction couls also have time-effect.[Conclusion] Spinal orthopedic shelf is an effective method for kyphosis and can be used in treating vertebral fracture and many spinal diseases after operations. |
