Comparative Study
Computer navigation in balloon kyphoplasty reduces the intraoperative radiation exposure.
Comparison of the dose area product (DAP), the radiation time and the operation time during computer navigated and conventional balloon kyphoplasty procedures. ⋯ The use of computer navigation systems in balloon kyphoplasty procedures reduces the radiation exposure of patients and surgeons significantly. The increased technical effort did not lead to a significant longer operation time. Hence, the use of computer navigation systems in balloon kyphoplasty procedures is recommended.
-
Validation study to define validity and reliability of an adapted and translated questionnaire. ⋯ The authors report the validation of a simplified Chinese SRS-22 for use in mainland China, which is culturally relevant, reliable, repeatable, psychometrically sound, and suitable for immediate clinical use.

An anatomic study conducted on cadaveric specimens. ⋯ S2 iliac technique is a potential option for distal fixation in spine surgery. Biomechanical and clinical data are required to fully evaluate the potential of this technique.

A descriptive cadaveric study. ⋯ The presence of both synoviocytes and chondrocytes has been recorded in the present study, suggesting that the uncovertebral interface is synovial in nature. Immunoreactivity to PGP 9.5, SP, CGRP, and NPY indicates the presence of nerve fibers from both the somatic and autonomic nervous systems. These findings suggest that the uncovertebral joints are potential pain generators in the cervical spine.

A morphometric analysis, using magnetic resonance imaging (MRI) studies of the lumbar spine. ⋯ The safe corridor for performing the discectomy and inserting the intervertebral cage narrows from L1-L2 to the L4-L5 level. This corridor is further narrowed with rotatory deformity of the spine. Using the preoperative MRI to assess the relative position of the adjacent neuro-vascular structures in relation to the lower vertebra's endplate at each level is recommended.
