Radiation exposure to the surgeon and the patient during kyphoplasty.
Prospective study of patients who underwent single or multilevel kyphoplasty for vertebral fractures. ⋯ Without eye or hand protection, the total radiation exposure dose to these areas would exceed the occupational exposure limit after 300 cases per year. Surgeons should wear lead lined glasses and keep their hands out of the radiation beam.

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.
