Review Case ReportsIntraoperative conjoined lumbosacral nerve roots associated with spondylolisthesis.
Lumbosacral nerve roots anomalies may produce low back pain. These anomalies are reported to be a cause for failed back surgery. ⋯ In this report, we describe our experience with a case of L5-S1 spondylolisthesis and associated congenital lumbosacral nerve root anomalies discovered during the surgical intervention, and the difficulties raised by such a discovery. Careful examination of coronal and axial views obtained through high-quality Magnetic Resonance Imaging may lead to a proper diagnosis of this condition leading to an adequate surgical planning, minimizing the intraoperatory complications.

Correction of post-traumatic thoracolumbar kyphosis using pedicle subtraction osteotomy.
The aim of this study was to retrospectively analyze and evaluate the effect of treatment employing pedicle subtraction osteotomy for chronic, posttraumatic thoracolumbar kyphosis. This study included 19 patients, 11 males and 8 females, with chronic, posttraumatic thoracolumbar kyphosis. Pre-operative kyphosis ranged from 31° to 63°. ⋯ No significant loss of correction was observed (loss of 1.7°), and solid fusion was achieved in all 19 patients. A single-stage posterior pedicle subtraction osteotomy is a safe and effective procedure for correction of posttraumatic thoracolumbar kyphosis. Using this technique, it is possible to safely obtain no greater than 55° of correction at a single level.

Comparative StudyIntramedullary nailing versus percutaneous locked plating of distal extra-articular tibial fractures: a retrospective study.
The aim of this study is to compare distal tibial fractures (4-10 cm proximal to the plafond) treated by intramedullary nailing with those treated by percutaneous locked plating and to assess the clinical and radiographic results, complication rates, and the need for secondary procedures. Thirty-six patients received percutaneous locked plate treatment and 25 patients received intramedullary nail treatment. The results obtained from these two treatment methods were assessed by comparing infection rates, starting time for wight-bearing, local implant irritation, union and malunion rates and along with secondary procedures. ⋯ The time to full weight bearing was shorter in the intramedullary nail group. There was no significant statistical difference in malunion and nonunion rates between the two groups. The need for secondary procedures was more common in group receiving the percutaneous locked plate treatment and the time to full weight bearing was shorter in the intramedullary nail group.

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.
