A novel posterior decompression technique (anterior sliding decompression osteotomy) for beak-type ossification of the posterior longitudinal ligament in the thoracic spine.
J Neurosurg Spine
January 2025
3Department of Orthopedic Surgery, Haeundae Bumin Hospital, Busan, South Korea.
Objective: Conventional decompression surgery for beak-type ossification of the posterior longitudinal ligament (OPLL) of the thoracic spine, whether approached anteriorly or posteriorly, poses several challenges, including technical complexity, cerebrospinal fluid leakage, incomplete decompression, and potential neurological deterioration. Therefore, the authors introduce a novel technique, anterior sliding decompression osteotomy (ASDO), for thoracic myelopathy caused by OPLL and evaluate the efficacy and safety of this technique.
Methods: Six patients (4 men and 2 women) who underwent ASDO surgery for beak-type OPLL in the thoracic spine with a follow-up period of at least 2 years were included in the cohort.
Proximal junctional disease 5 years after surgery for L4 degenerative spondylolisthesis: comparing PLIF versus minimally invasive decompression.
Eur Spine J

Department of Orthopaedic Surgery, Osaka Metropolitan University Graduate School of Medicine, Osaka, Japan.
Purpose: This study aimed to compare the incidence of radiological adjacent segment disease (R-ASD) at L3/4 between patients with L4/5 degenerative spondylolisthesis (DS) who underwent L4/5 posterior lumbar interbody fusion (PLIF) and those who underwent microscopic bilateral decompression via a unilateral approach (MBDU) at L4/5. Our ultimate goal was to distinguish the course of natural lumbar degeneration from fusion-related degeneration while eliminating L4/5 decompression as a confounder.
Methods: Ninety patients with L4/5 DS who underwent L4/5 PLIF (n = 53) or MBDU (n = 37) and were followed for at least 5 years were retrospectively analyzed.
A Martingale-Free Introduction to Conditional Gaussian Nonlinear Systems.

Department of Mathematics, University of Wisconsin-Madison, Madison, WI 53706, USA.
The conditional Gaussian nonlinear system (CGNS) is a broad class of nonlinear stochastic dynamical systems. Given the trajectories for a subset of state variables, the remaining follow a Gaussian distribution. Despite the conditionally linear structure, the CGNS exhibits strong nonlinearity, thus capturing many non-Gaussian characteristics observed in nature through its joint and marginal distributions.

Department of Neurosurgery, Southmead Hospital, North Bristol NHS Trust, Bristol, GBR.
The occipital sinus is often thought of as a redundant vestigial structure in adults. However, in rare cases, it can form the dominant route of intracerebral venous drainage, with a risk of significant surgical morbidity if unrecognised. We present an illustrative case describing this anatomical variant and tailoring of a midline suboccipital craniotomy to allow resection of a fourth ventricular epidermoid tumour with preservation of a dominant occipital sinus, and a review of the published literature.

Objective: Miniscrews are commonly utilized as temporary anchorage devices (TADs) in cases of maxillary protrusion and premolar extraction. This study aimed to investigate the effects and potential side effects of two conventional miniscrew configurations on the maxillary incisors.
Methods: Eighty-two adult patients with maxillary dentoalveolar protrusion who had undergone bilateral first premolar extraction were retrospectively divided into three groups: non-TAD, two posterior miniscrews only (P-TADs), and two anterior and two posterior miniscrews combined (AP-TADs).
