Observational Study
Transforaminal Unilateral Biportal Endoscopic Spinal Surgery for Extraforaminal Lumbar Disc Herniation (ELDH): A Retrospective Observational Study.
Biportal endoscopic spinal surgery (BESS) is recommended as a safer and less destructive option for lumbar disc herniations. However, limited data exist on clinical outcomes for extraforaminal lumbar disc herniation (ELDH) surgery. This retrospective study presents our preliminary experience with transforaminal unilateral BESS for ELDH. ⋯ Transforaminal unilateral BESS is an alternative and feasible method for treating ELDH, producing good surgical outcomes with few complications and sustaining pain improvement. Future studies with larger patient numbers and comparisons between BESS and other minimally invasive techniques for ELDH are warranted.

Posterior lumbar interbody fusion (PLIF) with cortical bone trajectory (CBT) screw fixation (CBT-PLIF) shows potential for reducing adjacent segmental disease. Previously, our investigations revealed a relatively lower fusion rate with the use of carbon fiber-reinforced polyetheretherketone (CP) cages in CBT-PLIF compared with traditional pedicle screw fixation (PS-PLIF) using CP cages. This study aims to evaluate whether the implementation of titanium-coated polyetheretherketone (TP) cages can enhance fusion outcomes in CBT-PLIF. ⋯ Examination of temporal changes in fusion rates reveals that only the TP group achieved a peak fusion rate 1 year postoperatively. This implies that TP cages may enhance the fusion process even after CBT-PLIF. Nevertheless, the definitive efficacy of TP cages for CBT-PLIF remains uncertain in the context of overall fusion rates.

This study aims to investigate the connection between the leakage sign (LS) and hematoma expansion (HE) in cases of spontaneous intracerebral hemorrhage. The investigation employs dual-energy computed tomography angiography (DECTA). ⋯ DECTA-based DE-LS stands out as an independent predictor of HE. The utilization of RR values over OR values is endorsed when assessing the risk of HE prediction.

This study aimed to evaluate prognostic factors including pre-radiosurgical blood count in elderly patients (EPs) with brain metastasis (BM) who were treated using linear accelerator (LINAC)-based stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (fSRT) with a micro-multileaf collimator. ⋯ The findings of our study highlight the efficacy of LINAC-based SRS and fSRT with a micro-multileaf collimator in the treatment of EPs with BMs. Neutrophil/lymphocyte ratio can be an important factor in treatment decisions for EPs with BMs.

This study aimed to evaluate the efficacy of unilateral pediculectomy and reduction with short-segment pedicle screw fixation for thoracolumbar burst fracture. ⋯ Unilateral pediculectomy and reduction with short-segment fixation and interbody fusion served as an efficient surgical method for thoracolumbar burst fracture.
