The advantage of percutaneous kyphoplasty in patients with Kummell's disease without symptoms of spinal cord compression

Objective To investigate the advantages of curative effect of percutaneous kyphoplasty in the treatment of patients with Kummell's disease without symptoms of spinal cord compression, and provide theoretical support for the treatment. Methods Retrospective analysis of 128 cases patients with Kummell's disease without symptoms of spinal cord compression who underwent surgery treatment from January 2016 to January 2018 in our hospital. According to the operation, they were divided into control group(percutaneous vertebroplasty, PVP operation, 61 cases) and experimental group(percutaneous kyphoplasty, PKP operation, 67 cases). The statistical differences of clinical data, vertebral height improvement, Cobb Angle and complications between the two groups were compared. Results Compare of the operative time and the amount of bone cement injected, the experimental group were significantly increased than the control group(all P<0.05). After operation, the height of the anterior vertebral walls(17.14±3.36) mm and median vertebral walls(16.25±4.37) mm of the experimental group were significantly raised compared with those of the control group[(11.74±4.34) mm and(12.53±4.21) mm, P<0.05]. The difference in ODI and Cobb Angle after surgery between the two groups was statistically significant(P<0.05). There was no statistical significance in hospital stay, the height of the posterior vertebral walls, postoperative infective complications between the two groups(all P>0.05). Conclusion PKP can effectively reduce the height of vertebral body and correct the kyphosis through the combination of body position reduction and balloon dilation when treating patients with Kummell's disease without symptoms of spinal cord compression, and it is also more conducive to the full filling of bone cement in the cleft of vertebral body. PKP can increase the riveting effect of bone cement and reduce the risk of leakage of bone cement, which shows its advantages in reducing the incidence of complications of adjacent vertebral fractures and spinal cord compression.
