文题释义:
硫酸钙骨水泥:该材料是α晶体结构,在体内具有恒定再吸收作用,注射后可向四周弥散,在体内快速固化,其固化后可增强骨强度,临床上可用于四肢干骺端骨缺的修复,作为松质骨区域移植替代材料,该修复方法为微创植骨创造了条件。
球囊扩张技术:是将一种可膨胀球囊置入塌陷的椎体内,在骨科最常见的为球囊扩张椎体后凸成形技术,通过球囊扩张恢复椎体高度,对后凸畸形进行矫正,减轻关节面间的磨损,允许在低压力下灌注骨水泥,它与骨水泥配合能够微创操作下缓解患者的疼痛,是由气囊导管技术发展起来的创新性技术。
 
 
背景:球囊扩张技术对脊柱后凸畸形具有重要的矫正作用,将其应用于扩张椎体后凸成形中可形成空腔,在低压力下灌注骨水泥,为脊柱的稳定性奠定基础。
目的:探讨球囊扩张可注射硫酸钙骨水泥填充治疗胫骨平台塌陷骨折的可行性,分析其临床应用效果。
方法:取新鲜成年人胫骨上段标本24个,制作胫骨平台Schatzker Ⅲ型塌陷骨折模型后,随机分为3组:标准组进行开窗撬拨复位自体骨移植松质骨拉力螺钉内固定治疗,单纯骨水泥组进行球囊扩张复位硫酸钙骨水泥填充治疗,骨水泥螺钉组进行松质骨拉力螺钉内固定联合球囊扩张复位硫酸钙骨水泥填充治疗,观察复位固定的一般情况,测量复位效果。

结果与结论:①模型固定效果:3组模型均复位良好,标准组、单纯骨水泥组、骨水泥螺钉组复位后的平均位移分别为(-0.22±0.62),(-0.23±0.67),(-0.20±0.69) mm,3组位移比较比较差异无显著性意义(P > 0.05);②临床应用效果:选择1例左侧胫骨平台Schatzker Ⅲ型骨折患者,进行松质骨拉力螺钉内固定联合球囊扩张复位硫酸钙骨水泥填充治疗,术后3 d复查X射线可见硫酸钙骨水泥;术后30 d复查,关节活动范围较好,硫酸钙部分吸收;术后60 d复查,关节无伸直障碍,X射线显示骨折愈合,硫酸钙吸收;③结果表明:经皮球囊扩张可注射硫酸钙骨水泥填充治疗胫骨平台塌陷骨折具有可行性,有临床应用价值。

Abstract:

BACKGROUND: The balloon dilatation technique plays an important role in the correction of kyphosis. A balloon catheter can enlarge the spinal cavity in kyphoplasty followed by injection of bone cement under low pressure to lay a foundation for the stability of the spine.

OBJECTIVE: To explore the feasibility of balloon dilation with injectable calcium sulfate cement for tibial plateau fractures and to analyze its clinical effect.

METHODS: Twenty-four upper tibia specimens of the adults were taken to make the Schatzker III collapsed fracture model of the tibial plateau. Then, these specimens were randomized into three groups: the standard group was subjected to poking reduction with autologus bone grafting and screw internal fixation, the bone cement group was inflated with balloon dilatation followed by calcium sulfate cement injection, and the combined group was treated with fixation with cancellous bone screws and balloon dilatation followed by injection of calcium sulfate cement. The general situation of reduction and fixation was observed and the reduction effect was measured.
RESULTS AND CONCLUSION: (1) Fixation effect in the model: All three models were well reset, and the average displacement of the standard group, the simple bone cement group and the bone cement screw group was (-0.22±0.62), (-0.23±0.67), and (-0.20±0.69) mm, respectively. There was no significant difference in the displacement between the three groups (P > 0.05). (2) Clinical application: One case of Schatzker type II fracture of the left tibial plateau was treated with cancellous bone screw fixation and balloon dilatation followed by injection of calcium sulfate cement. X-ray results showed calcium sulfate cement was visible at 3 postoperative days. At 30 postoperative days, the patient presented with good joint range of motion, and the calcium sulfate was partially absorbed on the X-ray film. At 60 postoperative days, the patient appeared to have no joint extension disorder, and fracture healing and absorption of calcium sulfate as shown by X-rays. To conclude, the balloon dilation with injectable calcium sulfate cement for the treatment of tibial plateau fracture is feasible and has clinical value.
