Is there a stable vertebral height restoration with the new radiofrequency kyphoplasty? A clinical and radiological study.
The aim of this study is to evaluate whether radiofrequency kyphoplasty can restore vertebral body height in osteoporotic vertebral fractures and whether restoration of vertebral height correlates with decreased pain. ⋯ Radiofrequency kyphoplasty achieves rapid and lasting improvement in clinical symptoms. There was stable restoration of vertebral body height with a mean cement volume of 3.0 ml ± 0.6. There was no correlation between restoration of vertebral body height and pain relief.

Relationship between postoperative axial symptoms and the rotational angle of the cervical spine after laminoplasty.
An axial symptom is one of the postoperative problems after cervical laminoplasty. The range of motion (ROM) of the cervical spine decreases after laminoplasty. It is speculated that the reduction in neck ROM is one of the causes of axial symptoms. However, most reports have focused on ROM of the cervical spine in flexion and extension, and few papers describe the rotational motion after surgery. It is impossible to assess the rotational motion in plain X-rays. This study was undertaken for the following two purposes: (1) to compare segmental rotational angles of the cervical spine between control subjects and patients with cervical laminoplasty ; (2) to analyze the relationship between postoperative axial symptoms and the range of cervical rotational angle after laminoplasty. ⋯ Reduction of the rotational angle in the cervical spine was clearly observed in patients with cervical laminoplasty, compared to that in the controls. The marked reduction might be related to the axial symptoms after laminoplasty.

Hydroxycamptothecin liposomes inhibit collagen secretion and induce fibroblast apoptosis in a postlaminectomy rabbit model.
To design and attest the role of hydroxycamptothecin liposomes (L-HCPT) as a new delivery system to prevent epidural scar adhesions after laminectomy in a rabbit model. ⋯ These results demonstrate that the treatment of postlaminectomy wounds with L-HCPT may reduce and prevent the severity of adhesion.
