Background: Balloon kyphoplasty is a new technique of microtraumatic surgery of spine developed in recent years, and brings a new pathway for the treatment of osteoporotic vertebral fracture in the elderly. Objective: To investigate the therapeutic effect of percutaneous balloon kyphoplasty on osteoporotic vertebral fracture, and to explore the main point of injecting bone cement. Methods: A total of 22 patients with osteoporotic vertebral fracture at the age of 60-78 years underwent percutaneous balloon kyphoplasty under C-arm fluoroscopy. In accordance with the standards of WHO, antalgic effects were evaluated. The injection time, manner and dose of bone cement were analyzed. Results and Conclusion: All patients were followed up for 1-12 months. Postoperative pain was completely lessened in 15 patients, and partially relieved in 7 cases, with an effective rate of 100%. Spinal mobility increased. No incision surgery was needed in all patients. No complications such as pulmonary embolism or nerve injury appeared. These results indicate that percutaneous balloon kyphoplasty for treatment of osteoporotic vertebral fractures is minimally invasive and simple, has less complication and effectively reconstructs vertebral body strength, and can better alleviate the pain, is an effective minimally invasive spinal treatment technology. To strictly understand the main treatment point can obtain satisfactory clinical curative effects, including precise diagnosis of the disease, identification whether patient's pain is induced by fractures, preoperative intraoperative exact localization of the affected vertebra, perfect puncturing technique, suitable postoperative treatment and nursing. It is also important to strictly master the time of injecting bone cement and the dose of bone cement. Bone cement injection was commonly done in drawing-wire stage. Too early injection easily induced leakage and toxic reaction. Too late injection affected the expansion of bone cement and therapeutic effects. The injection of bone cement should be finished under a perspective environment, which can effectively avoid bone cement leakage.

Objective: To investigate the "optimal projecting angle range" for clearly displaying the opening of uterine artery on DSA. Methods: Standard anterior-posterior (A-P) position and rotation observation of the opening of uterine artery was conducted on CTA 3D VR and MIP images in 12 patients. The internal and external relationships between the opening of uterine artery and its attached arteries on A-P position images were analyzed, and the small projection angle range, on which the opening of uterine artery could be clearly revealed on the left and right oblique projection, was determined. The accuracy of the projection angle range used for clearly displaying the opening of uterine artery was evaluated by DSA examination in 27 patients with the same projection method. Results: The openings of 41 uterine arteries were located at the lateral part of the attached arteries, which were clearly displayed on the images obtained by tilting 10°-40° toward to the opposite side. The openings of 13 uterine arteries were located at the medial part of the attached arteries, which were clearly displayed on the images obtained by tilting 30°-50° toward to the ipsilateral side. The openings of 24 uterine arteries were located at the anterior part of the attached arteries, which were clearly displayed on the images obtained by tilting 40°-60° toward to the opposite or ipsilateral side. Conclusion: The use of "optimal projecting angle range" can easily and clearly display the opening of uterine artery on DSA.
