THERMAL RADIOFREQUENCY ABLATION COMBINES WITH CORTICOSTEROID INJECTION IN MANAGEMENT OF LUMBAR FACET JOINT PAIN: A SINGLE-CENTER STUDY IN VIETNAM.
We sought to evaluate the effectiveness of thermal radiofrequency ablation combined with corticosteroid injection for medial branch block in the management of chronic low back pain, which originates from lumbar facet joint (LFJ) pain. ⋯ Thermal radiofrequency ablation combined with corticosteroid injection should be a potential method of choice for its effectiveness, long-lasting effect, and safety in the management of LFJ pain.

The role of surgery in recurrent glioblastoma multiforme (GBM) remains a controversial topic. The goal of this study was to perform a case control analysis including time to tumor recurrence as an additional prognostic factor in order to determine which patients benefit most from repeat surgery. ⋯ Surgery for recurrent GBM leads to improved survival independent of age, Karnofsky Performance Scale, and time to tumor recurrence. Patients with time to tumor recurrence >6 months benefit most from additional surgery.

Due to the lack of an additional anterior plate, the motion stability of a zero-profile device with an anchored cage (AC) may be inferior to that of a traditional plate-cage construct (PCC). However, the impact of this difference in motion stability on various outcomes has not been fully explored. Therefore, the aim of this study was to compare the motion stabilization features of an AC and a PCC and analyze their impact on postoperative outcomes and complications. ⋯ More attention should be given to minimizing the adverse impact of poor motion stability in the design and development of future zero-profile cervical implants, although this has little impact on clinical efficacy.

The objective of the study was to assess the esthetic efficacy of acellular dermal matrix (ADM) implantation to prevent frontotemporal depression (FTD) following minipterional craniotomy (MPT) to clip unruptured intracranial aneurysms. ⋯ Even MPT cannot completely prevent FTD in the retroorbital region. ADM implantation in MPT can help to improve esthetic satisfaction.

A variety of applications related to neurosurgical procedures, education, and training require accurate reconstruction of the involved structures from the medical images such as computed tomography (CT). This study evaluates the quality of CT-based reconstruction of dry skull bones for advanced neurosurgical applications. The accuracy and precision of these models were examined with reference optical scanning. ⋯ The study reveals that bone structure, complexity, and segmentation threshold lead to CT reconstruction variability. The trade-off between the desirable model and accepted mean deviation should be considered as per traits of the desired application.
