Abstract

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.
