The surgical approach and treatment of thoracolumbar osteoporotic vertebral collapse with neurological deficit have not been documented in detail. Anterior surgery provides good decompression and solid fusion, but the surgery-related risk is relatively higher than that associated with the posterior approach. In posterior surgery, the major problem after posterior correction and instrumentation is failure to support the anterior spinal column, leading to loss of correction of kyphosis. The aim of this study was to evaluate the efficacy of reinforcing short-segment posterior fixation with vertebroplasty and to compare the outcome with those of posterior surgery without vertebroplasty and anterior surgery, retrospectively. ⋯ The results suggest that additional reinforcement with vertebroplasty reduces the kyphotic loss and instrumentation failure, compared with patients without the reinforcement of vertebroplasty. Vertebroplasty-augmented short-segment fixation seems to offer immediate spinal stability in patients with thoracolumbar osteoporotic vertebral collapse; the effect seems equivalent to that of anterior reconstruction.

The authors performed a retrospective clinical study to evaluate the feasibility and accuracy of cervical pedicle screw (CPS) placement using 3D fluoroscopy-based navigation (3D FN). ⋯ Three-dimensional fluoroscopy-based navigation can improve the accuracy of CPS insertion; however, severe CPS malpositioning that causes injury to the vertebral artery or neurological complications can occur even with 3D FN. Advanced techniques for the insertion of CPSs and the use of modified insertion devices can reduce the risk of a malpositioned CPS and provide increased safety.

Comparative Study
Assessment of sexual dysfunction before and after surgery for lumbar disc herniation.
Object Sexuality is an important aspect of human life. Sexual activity may be affected in lumbar disc herniation through different mechanisms. The aim of this study is to evaluate patients' sexual problems and sexual behavior patterns before and after surgical treatment of lumbar disc herniation. ⋯ Conclusions Lumbar disc herniation has negative effects on sexual life, and not enough attention is given to the patients' sexual problems by the physicians. Decreased sexual desire and decreased sexual intercourse are the most commonly reported problems. Taking time during examination and giving simple recommendations may improve sexuality and life quality of the patients.

The goal of this study was to determine the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE) after spine surgery. Another purpose was to clarify the rapid changes of the fibrin monomer complex (FMC) and D-dimer levels during the perioperative period of spine surgery for early diagnosis of venous thromboembolism (VTE). ⋯ In this study the prevalence of VTE after spine surgery was 8.3%. The FMC measured 1 day after spine surgery is considered to be useful as an indicator of VTE.
