Clinical Trial
The results of a consecutive series of dynamic posterior stabilizations using the PercuDyn device.
To evaluate the results of a consecutive series of patients affected by lumbar discogenic pain associated with facet pain and canal stenosis surgically treated with the PercuDyn device. ⋯ In this wide cohort study, the PercuDyn ensured good clinical and radiological results, with more than 70 % of patients satisfied of the procedure. Very few complications were noted, with an immediate return to daily activities. At longer follow-ups, 10 % of patients received revision surgery.

1. To investigate the incidence of closed-type PSIS in the Korean population. 2. To categorize the morphological features of Korean sacrum. 3. To measure the safe marginal length and angle for screw fixation considering the PSIS and course of the external iliac vein, using a Korean sacrum model. ⋯ With reference to these parameters, the optimal screw length and angle can be chosen and bicortical anteromedial screw fixation can be easily and safely performed.

A retrospective study was designed to evaluate clinical outcomes and sagittal alignment following single-level unilateral instrumented transforaminal lumbar interbody fusion (TLIF). ⋯ Unilateral instrumented TLIF is a safe and effective treatment option for single-level lumbar degenerative disease, and is less invasive, yields good outcomes and has a low complication rate. In addition, the procedure has the potential to partly restore sagittal alignment.

Sacral chordoma is a rare low-to-intermediate grade malignant tumour. The mainstay of treatment is still surgery with en bloc and wide resection margins, which can grant the best chances of a long-term control or cure of this disease. The first aim of this paper is to collect data about survival, time to local recurrence and metastasis among patients affected by sacral chordoma and primarily treated with surgery. The second aim is to analyze the influence of level resection, tumor volume and surgical margins on local recurrence. ⋯ Solid survival at long-term follow-up can be achieved by a surgical resection performed with wide margins.

To evaluate a radiological and clinical difference between the curvilinear type cages compared to the straight type cages for the restoration of lumbopelvic sagittal alignment and its maintenance after transforaminal lumbar interbody fusion (TLIF) procedure. ⋯ This study demonstrates that the curvilinear type cage is superior to the straight type cage in improving the SL and maintaining both the restored lumbopelvic parameters and elevated disc height. These results could be attributable to the anterior position of the curvilinear cage which permits easy restoration of segmental lordosis and less sinking of cages.
