Randomized Controlled Trial
Treatment of unstable thoracolumbar fractures: does fracture level fixation accelerate the bone healing?
To investigate the effect of fusion on short segment including fractured level (SSIFL) and long segment (LS) transpedicular fixation after acute thoracolumbar junction burst fractures. The 2-year clinical and radiologic follow-up results of the 2 groups also were compared. ⋯ Fusion occurred sooner and patients experienced earlier clinical recovery in the SSIFL group compared with the LS group.

Traumatic injury of the posterior communicating artery or the basilar artery causing arteriovenous fistulae is rare. ⋯ To our knowledge, this is the first such report worldwide.

Although the Pipeline Embolization Device (PED) has proved to be an excellent option for internal carotid artery (ICA) aneurysms, the rate of occlusion remains difficult to predict and factors associated with aneurysm occlusion are not well elucidated. This study aimed to investigate predictors and the rate of occlusion for aneurysms along the ICA. ⋯ The rate of occlusion after PED is highest for small proximal ICA aneurysms and the probability of occlusion is lower for distal ICA aneurysms.

Comparative Study
Hybrid Bone SPECT/CT imaging in evaluation of chronic low back pain.Correlation with facet joints arthropathy.
Evidence to support the use of bone hydroxydiphosphonate (HDP) single photon emission computed tomography (SPECT/CT) in patients with facetogenic low back pain (LBP) is still limited. In this study we compared the scintigraphic patterns on bone SPECT/CT with the degree of structural facet joint (FJ) degeneration on CT in patients with LBP. ⋯ The ability of SPECT/CT to precisely localize scintigraphically active FJs may provide significant improvement in the diagnosis and treatment of patients with LBP. In this study we demonstrate that in >40% of FJs, the scintigraphic patterns on SPECT/CT did not correlate with the degree of degeneration on CT.

Case Reports
Surgical treatment of cavernous malformations involving the midbrain:a single center case series of 34 patients.
Cavernous malformations (CMs) involving the midbrain are more challenging for surgical treatment than are CMs at other sites because of the surrounding critical structures and deep location. However, specific features and treatment strategies have not been well illustrated. ⋯ Although surgery for MBCMs is associated with significant perioperative morbidity and mortality, most patients show favorable outcomes. Higher preoperative mRS score is an independent predictor of poor functional outcome.
