Therapeutic effects of temporary retention one side of balloon kyphoplasty on vertebral compression fractures
Abstract
The aim of this study was to evaluate the therapeutic effects of single-balloon percutaneous kyphoplasty (PKP) on elderly patients with vertebral compression fractures. Sixty-nine elderly patients with osteoporotic vertebral compression fractures were given single-balloon PKP. When a balloon was kept on one side of the vertebral body, methyl methacrylate was injected into the vertebral body on the other side. The anterior vertebral height change, sagittal Cobb angle change, injection amount of bone cement, visual analogue scale (VAS) score and Oswestry disability index (ODI) were determined. The average surgical time was (48.5 ± 12.4) min, blood loss was (23.1 ± 8.5) ml, pressure of balloon was 180-250 Psi and its volume was (3.6 ± 1.1) ml. The injection amount of bone cement was (8.2 ± 2.4) ml. The compression ratio of anterior vertebral height and Cobb angle after balloon expansion were significantly different from those after postural reduction or balloon release (P<0.05). The VAS score and ODI before surgery were significantly different from those two days after surgery or during follow-up (P<0.05). During follow-up, 5 new cases of vertebral compression fractures occurred, with 2 involving neighboring vertebrae. The average time from last fracture was 7.6 months. Single-balloon PKP had significant short-term therapeutic effects on elderly patients with vertebral compression fractures.
