Clinical TrialMinimally invasive transpedicular vertebrectomy for metastatic disease to the thoracic spine.
We present a series of 8 patients with thoracic metastatic disease causing acute neurologic decline. We present minimally invasive posterolateral vertebrectomy and decompression as an effective approach in patients with significant comorbidities and as palliative care. ⋯ Minimally invasive transpedicular vertebrectomy is an effective palliative treatment option for thoracic metastatic disease in patients not eligible for more extensive anterior transthoracic surgery and stabilization.

Randomized Controlled TrialThe effect of meperidine-impregnated autogenous free fat grafts on postoperative pain management in lumbar disc surgery.
Prospective, randomized, double-blind clinical study. ⋯ In this study, we helped patients, who underwent 1-level, first-time lumbar microdiscectomy have a postoperative pain-free and comfortable period by using epidural meperidine-impregnated AFFGs.

Controlled Clinical TrialFacet joint orientation in spondylolysis and isthmic spondylolisthesis.
The orientation of facet joints (FJs) in a normal population and isthmic spondylolisthesis (IS) population was assessed using magnetic resonance imaging in the lumbar spine. ⋯ Relative coronal FJO in the lumbar spine may be the phenotypic expression of the familial etiology of IS. This may result in increased stress concentration in the pars between or below coronally oriented FJs. These more coronal FJOs in IS may also explain the common observation of retrolisthesis at L4/5 above IS when the L4/5 disc degenerates, lateral overhang of the L4/5 FJ to the L5 pedicle entry point above an IS, and the rare combination of DS at L4/5 and IS at L5/S1 when both disorders are separately common. This latter observation can be explained by the observation that DS occurs in those individual with sagittal lumbar facets, and that IS occurs in those with more coronal FJs.
