Randomized Controlled TrialCT-guided nucleoplasty with radiofrequency energy for the treatment of lumbar disk herniation.
A clinical randomized controlled trial. ⋯ The results of this study suggest that CT-guided nucleoplasty with radiofrequency energy is a relative effective and safe technique for treating leg pain caused by radicular encroachment. Furthermore, nucleoplasty combined with nerve root injection had achieved a significant greater improvement in pain management and functional level in short term (within 1 mo) after treatment than nucleoplasty alone.

Comparative StudyA comparison of cell salvage strategies in posterior spinal fusion for adolescent idiopathic scoliosis.
Retrospective case-control study. ⋯ The present study demonstrates the efficacy of a combined intraoperative and postoperative cell salvage strategy in PSF for AIS, significantly reducing perioperative donor blood transfusions, maintaining physiological Hct, and conserving blood bank resources.

Immediate reduction under general anesthesia and single-staged anteroposterior spinal reconstruction for fracture-dislocation of lower cervical spine.
Fracture-dislocation of the lower cervical spine is a severe traumatic lesion, most frequently resulting in tetraplegia. Treatment is usually painful and time consuming. This retrospective study evaluated the clinical curative effect of immediate reduction under general anesthesia and single-staged anteroposterior spinal reconstruction for fracture-dislocation of the lower cervical spine. ⋯ The spinal cord function grades according to American Spinal Injury Association after operation were as follows: grade A in 1 case, grade B in 1 case, grade C in 3 cases, grade D in 3 cases, and grade E in 4 cases. All 12 patients showed evidence of stability at the instrumented level on the final follow-up examination (mean follow-up, 3.7 y). Immediate reduction under general anesthesia followed by a single-stage combined anteroposterior spinal reconstruction is a safe and reliable way of treating patients with lower cervical spine fracture-dislocations.

Clinical application of the "pedicle exposure technique" for atlantoaxial instability patients with a narrow c1 posterior arch.
This was a retrospective study. ⋯ The "pedicle exposure technique" is an effective alternative in patients with the C1 posterior arch measuring <4 mm. In consideration of a high screw entry point on the C1 posterior arch, similar to the C1 posterior arch screw technique, we propose that this new technique can reduce venous plexus and C2 nerve root injury while providing effective biomechanical stability.

Case ReportsProximal instrumented vertebral body chance fracture after pedicle screw instrumentation in a thoracic kyphosis patient with osteoporosis.
We present a case of proximal vertebral body chance fracture after pedicle screw instrumentation and fusion in a 67-year-old woman with osteoporosis and thoracic kyphosis. ⋯ Chance fracture in osteoporotic bone at the proximal end of a construct due to a pedicle screw is a rare complication but it may result in catastrophic consequences. Early recognition of this complication, reduction of the fraction-dislocation, and an extension of the instrumentation can be utilized for realignment and long-term stabilization.
