Comparison of percutaneous vertebroplasty and percutaneous kyphoplasty for the management of Kümmell's disease: A retrospective study.

2015 
Background: Post traumatic osteonecrosis of a vertebral body occurring in a delayed fashion was first described by the German doctor Kummell in 1895. Several studies have reported percutaneous vertebroplasty (PVP), or percutaneous kyphoplasty (PKP) for Kummell's disease achieves good outcomes. However, it is unknown whether a technique is superior for the treatment of this disease. The objective of the study is to compare the efficacy of PVP and PKP for the treatment of Kummell's disease. Materials and Methods: A retrospective review was conducted for 73 patients with Kummell's disease. PVP was performed in 38 patients and PKP in 35 patients. Visual analogue score (VAS) was used to evaluate pain. The anterior vertebral height was measured. The operative time, the incidence of cement leakage and the costs were recorded. Results: In both PVP group and PKP group, the VAS and anterior vertebral height significantly improved at 1-day postoperatively ( P P > 0.05). Between the PVP and PKP groups, there were no significant differences in VAS and the anterior vertebral height at 1-day postoperatively and at the final followup ( P > 0.05). The operating time and expense in the PKP group were higher than the PVP group ( P P Conclusions: PVP is a faster, less expensive option that still provides a comparable pain relief and restoration of vertebral height to PKP for the treatment of Kummell's disease. PKP has a significant advantage over PVP in term of the fewer cement leakages.
