Randomized Controlled TrialComparison of the therapeutic effect of teriparatide with that of combined vertebroplasty with antiresorptive agents for the treatment of new-onset adjacent vertebral compression fracture after percutaneous vertebroplasty.
Comparing a prospective group of 32 patients, who underwent percutaneous vertebroplasty (PVP) and who were treated with teriparatide for at least 18 months after a new-onset adjacent vertebral compression fracture (VCF), and compared it with a retrospective group of 33 patients, who received antiresorptive agents combined with repeated PVPs for post-PVP new-onset adjacent VCFs. ⋯ For the treatment of new-onset adjacent VCF after PVPs, the therapeutic effects of teriparatide is better than that of the combined vertebroplasty and an antiresorptive agent in fracture prevention, BMD change, and sustained pain relief.

Clinical TrialTotal en bloc spondylectomy for spinal metastasis of differentiated thyroid cancers: a long-term follow-up.
A retrospective case series. ⋯ TES was effective in controlling spinal thyroid cancer metastasis locally and in preserving the ability to walk. However, instrumentation failure and other late complications arose during the patients' long survival times after TES.

Treatment of facet cysts associated with neurogenic intermittent claudication with x-stop.
Facet degeneration often leads to the formation of synovial facet cysts. As facet cysts invade the spinal canal, they become a contributing factor to spinal stenosis. Previous studies have demonstrated successful treatment of neurogenic intermittent claudication (NIC), a major symptom of spinal stenosis, with an interspinous process device. ⋯ No statistical difference was noted in any of the outcome measures among patients with small facet cysts, large facet cysts, or without facet cysts when treated with an interspinous process device. We can thus conclude that X-Stop is an appropriate treatment consideration for NIC with or without the presence of synovial facet cysts.

Comparative analysis of isocentric 3-dimensional C-arm fluoroscopy and biplanar fluoroscopy for anterior screw fixation in odontoid fractures.
Retrospective clinical study. ⋯ Iso-C significantly decreased surgical time. At last follow-up iso-C assistance was associated with improved rates of radiographic fusion with comparable outcome and complication profiles. This series represents the largest cohort of patients treated with intraoperative real-time navigation assistance for odontoid fractures.

Analysis of C5 palsy after cervical open-door laminoplasty: relationship between C5 palsy and foraminal stenosis.
A retrospective study. ⋯ There was a significant difference in the diameter of the C4/5 foramen between the PG and the NPG. The results suggest that the main etiology of C5 palsy is impairment of the C5 nerve root induced by preexisting C4/5 foraminal stenosis.
