Balloon Kyphoplasty: An Effective Treatment for Kummell Disease?

Abstract

ObjectiveThe purpose of this study was to evaluate the efficacy of balloon kyphoplasty for treating Kummel disease accompanying severe osteoporosis.MethodsTwelve patients with single-level Kummell disease accompanied by severe osteoporosis were enrolled in this investigation. After postural reduction for 1 or 2 days, balloon kyphoplasty was performed on the collapsed vertebrae. Clinical results, radiological parameters, and related complications were assessed at 7 days, 1 month and 6 months after the procedure.ResultsPrior to kyphoplasty, the mean pain score (according to the visual analogue scale) was 8.0. Seven days after the procedure, this score improved to 2.5. Despite the significant improvement compared to preoperative value, the score increased to 4.0 at 6 months after the procedure. The mean preoperative vertebral height loss was 55.4%. Kyphoplasty reduced this loss to 31.6%, but it increased to 38.7% at 6 months after the procedure. The kyphotic angle improved significantly from 22.4°±4.9° (before the procedure) to 10.1°±3.8° after surgery, However, the improved angle was not maintained 6 months after the procedure. The mean correction loss for the kyphotic deformity was 7.2° at 6 months after the procedure. Three out of 12 patients sustained adjacent fractures after balloon kyphoplasty within 6 months.ConclusionAlthough balloon kyphoplasty for treating Kummell disease is known to provide stabilization and pain relief, it may be associated with the development of adjacent fractures and aggravated kyphosis.

Comparison of the clinical outcomes of percutaneous vertebroplasty vs. kyphoplasty for the treatment of osteoporotic Kümmell’s disease:a prospective cohort study

“…After filling the fissures in the vertebral body with bone cement, the height and kyphosis deformity of the vertebral body were partially restored and corrected, and the abnormal activity of the injuried vertebral body was eliminated, which was an important reason for pain relief [11]. Previous studies have found that both PVP and PKP can effectively relieve the lower back pain of Kümmell's disease, achieve satisfactory clinical effect, and at the same time partially restore the height of the vertebra and correct the kyphosis [11,[21][22][23][24][25][26][27][28]. During spinal flexion and extension, due to the presence of IVC and the formation of false joints, the injured vertebra of Kümmell's disease can stretch and expand, which can widen the fractured vertebra.…”

During spinal flexion and extension, due to the presence of IVC and the formation of pseudojoint, the injured vertebra of Kümmell's disease can stretch and expand, which can widen the fractured vertebral body.…”

Comparison of the clinical outcomes and cement distribution patterns after percutaneous vertebroplasty in the treatment of thoracolumbar Kümmell’s disease and OVCFs

“…After filling the fissures with bone cement in the fractured vertebrae, the height of the vertebrae was partially restored and kyphosis deformity was partially corrected, and the abnormal activity of the fractured vertebrae was eliminated, which was an important reason for pain relief [2]. Previous studies have found that PVP can effectively relieve low back pain of Kümmell's disease and OVCFs, and partially restore vertebral height and correct kyphosis [2,[23][24][25][26][27][28][29][30]. The ODI and VAS scores in both Kümmell's disease and OVCFs groups decreased after PVP treatment, but the mean score in Kümmell's disease group was higher than that in OVCFs groups [31].…”
