[The influence of thoracic kyphosis on sagittal balance of the lumbosacral spine in thoracic idiopathic scoliosis patients].
To evaluate the influence of thoracic kyphosis to sagittal alignment and balance of the lumbosacral vertebrae in thoracic adolescent idiopathic scoliosis patients. ⋯ Sagittal alignment and balance of the lumbosacral vertebrae may influence the thoracic kyphosis in AIS patients. The mechanism of this influence may through the adaptation of upper arc of lumbar lordosis. This influence must be considered in thoracic adolescent idiopathic scoliosis patients who undergo selective posterior thoracic fusion.

[Reliability of magnetic resonance imaging in diagnosing posterior ligament complex injury in thoracolumbar fractures].
To analyze the reliability of magnetic resonance imaging (MRI) in detecting posterior ligament complex injury in thoracolumbar fractures. ⋯ A fat-suppressed T2-weighted sagittal sequence of MRI is a highly sensitive, specific, and accurate method to detect posterior ligament complex injury and which is recommended for the accurate evaluation of posterior ligament complex injury in thoracolumbar fractures.

[Safety analysis of laparoscopic adrenalectomy for adrenal pheochromocytoma of 5 to 10 cm].
To investigate the safety of laparoscopic adrenalectomy for adrenal pheochromocytoma with maximum diameter of 5 - 10 cm. ⋯ For adrenal pheochromocytoma with maximum diameter of 5 - 10 cm, the laparoscopic procedure decreased operative time, blood loss, blood-transfusion and postoperative hospital stay compared to traditional open surgery. Intraoperative hemodynamic values during laparoscopic adrenalectomy are comparable to those of traditional open surgery. Adrenal pheochromocytoma of 5 - 10 cm is not a contraindication of laparoscopic surgery and experienced urologists can perform it safely for large adrenal pheochromocytoma.

[Biomechanical effect of the iliac screw insertion depth on lumbo-iliac fixation construct].
To biomechanically compare the stability of the short and long iliac screw fixation constructs in lumbo-iliac reconstruction. ⋯ Under the physical loading, lumbo-pelvic fixation construct using the short iliac screw may obtain mechanical stability comparable to that by long iliac screw. The short iliac screw is only the half of the long iliac screw by length, could reduce the implantation risk. However, the long iliac screw behaves greater axial pullout force, should be applied as far as possible in the osteoporosis patient. The lumbo-pelvic reconstruction utilizing any length of iliac screw is difficult to restore the local stability.

[Classification of the pectus excavatum and minimally invasive Nuss procedure].
To investigate the improvement of the Nuss procedure with the classification of the pectus excavatum by symmetry and extend the indication of the operation for a better outcome. ⋯ To classify the pectus excavatum with symmetry and to choose different ways of procedure can extend the indication of Nuss procedure and receive a better outcome.
