Abstract:

BACKGROUND: Kyphoplasty with polyethylene terephthalate can relieve pain quickly, restore the vertebral height and correct kyphosis. However, there are less reports on percutaneous kyphoplasty to deal with the Kummell's disease.

OBJECTIVE: To evaluate the efficacy and safety of percutaneous kyphoplasty with polyethylene terephthalate in treating Kummell disease.
METHODS: Seventeen patients with Kummell disease (5 males and 12 females) aged 67 to 72 years old were included in this study. Affected vertebral segments included T11 in two cases, T12 in seven cases, L1 in five cases, L2 in two cases, and L3 in one case. All the patients were treated by percutaneous kyphoplasty with polyethylene terephthalate. Pain relief, living ability and imaging evaluations were performed before and after the surgery.
RESULTS AND CONCLUSION: (1) Pain relief: The Visual Analogue Scale scores in the 17 patients were significantly lowered at 3 days, 3 months and 6 months after the surgery than the preoperative scores (P < 0.05). (2) Living ability: The mean Oswestry disability index scores in 17 patients at 3 days, 3 months and 6 months after the surgery were lowered compared to the preoperative scores (P < 0.05). (3) Imaging evaluation: The height of the anterior and middle line vertebral body in 17 patients at 3 days, 3 months and 6 months after the surgery were higher than the preoperative (P < 0.05), and the Cobb angle was significantly lowered compared to the preoperative (P < 0.05). (4) Adverse reaction: There was no leakage of bone cement in the vertebral canal and vessels, and no adverse reactions related to bone cement occurred. These results suggest that the percutaneous kyphoplasty with polyethylene terephthalate is safe in treating elderly Kummell disease, which can relieve pain quickly, improve patients’ quality of life, and rebuild the spinal stability.
