ABSTRACT
Objective To explore the clinical effect of percutaneous osteoplasty with SKy bone expander system in the treatment of calcaneal fracture.Methods 63 feet of 55 patients with calcaneal fractures were involved in this study.According to Sanders fracture classification including 38 feet of Sanders Ⅱ,18 feet of Sanders Ⅲ,7 feet of Sanders Ⅳ.There were 6 to 16 days interval between the injuries and the surgeries.The patients were treated by percutaneous osteoplasty with the SKy bone expander system.The standard of operation was the satisfaction of reduction and Bohler's and Gissane's angles under X-ray.Results All of 63 feet of 55 patients were followed up for average 22 months.According to the criterion of therapeutic effect,the results were as follows:excellent in 30 cases,good in 26 cases,fair in 7cases,and no poor case.The excellent and good rate was 88.9％.Conclusion Percutaneous osteoplasty with SKy bone expander system in the treatment of calcaneal fracture,especially in reduction and fixation of Sanders type Ⅱ and Sanders type Ⅲ,can recover Bohler's and Gissane's angles,significantly shorten the duration of illness,and has fast recovery and can possess satisfactory curative effect,and it is worth popularizing.
ABSTRACT
Objective To evaluate the curative effect and complications of percutaneous puncture kyphoplasty in the treatment of vertebral compression fracture in the elderly. Methods 19 cases of vertebral compression fracture in the elderly patients with disc 25 PKP technology applications were diagnosed with the accurate positioning,local anesthesia a small incision of about 0. 3cm later puncture path through vertebral pedicle to the wound vertebra,After perspective is the accurate lateral, putting into high-pressure balloon, injecting the contrast agent into the balloon with high-pressure syringe gradually. The wound vertebra is blackmai until a high degree of vertebral distraction to the recovery basis under the C-arm, and then taking the balloon out after pumping the contrast agent out. Bone cement is mixed well and injected into the cavity of the wound vertebra slowly which is the result of balloon dilation,during that time under the control of bone cement inside the wound vertebra,then puting the working column out and surgery completed. Results The low back pain of 19 patients immediately disappeared or significantly reduced after the operation, and 8 postoperative patients is up that day, 11 cases is up the following day. The degree of the wound vertebra is recovered by X-ray examination, and the bone cement evenly distributed within the wound vertebra, no spills. This group of patients are followed up for an average of 18 months(1 ～24 months) ,using visual analog and digital method to determine changes in Iow back pain. The data are paired t test,P ＜ 0.01. It have significant difference of views.Conclusion Percutaneous kyphoplasty accurate cervical disc herniation and effective disarmament of the symptoms and signs, with trauma and rapid recovery, fewer complications, shorter course of treatment and so on, and it is a safe and effective way in the treatment of vertebral compression fracture in the elderly.
