To compare the stability of a corticopedicular posterior fixation (CPPF) device with traditional pedicle screws for decompression and fusion in adult degenerative lumbar spondylolisthesis. ⋯ CPFF fixation demonstrated similar segmental stability to traditional pedicle screw fixation whereas tensile forces and stress in surrounding cortical bone remained below the load to failure.

The present study compares postoperative outcomes between patients with and without sickle cell disease (SCD) undergoing 1-to 3-level lumbar spinal fusion for degenerative pathologies. ⋯ Patients with SCD undergoing lumbar spinal fusion demonstrate higher risks for coagulopathic, ischemic, and infectious-related complications, as well as long-term postoperative opioid use. Awareness of the unique complication profile in SCD patients may help guide surgeons in refining perioperative management strategies to optimize outcomes in patients with SCD.

Application of Synthetic TOF-MRA-CT Fusion Imaging in Preoperative Planning for Aneurysm Clipping Surgery: A Comparative Study with 3D-CTA.
Some patients with intracranial aneurysms (IAs) cannot undergo three-dimensional computed tomography angiography (3D-CTA) or digital subtraction angiography due to contraindications to contrast agents or radiation. Time-of-flight magnetic resonance angiography (TOF-MRA) offers a contrast-free alternative but lacks cranial bone detail critical for surgical planning. This study evaluates the feasibility of using 3D Slicer to fuse TOF-MRA with thin-section CT images to generate synthetic images resembling CTA for surgical clipping planning. ⋯ Synthetic TOF-MRA-CT fusion images closely match 3D-CTA for ≥3 mm aneurysms, demonstrating comparable diagnostic and surgical clipping planning effectiveness. They represent a promising alternative for personalized preoperative planning, particularly when contrast agents are contraindicated.

Anterior pituitary dysfunction is one of the major causes of disability and morbidity in patients suffering from traumatic brain injury (TBI). The present study was undertaken to evaluate the incidence of anterior pituitary dysfunction in cases of moderate and severe TBI, its value in long-term prognostication, and the factors that predispose to a higher incidence of anterior pituitary dysfunction in acute and chronic phases. ⋯ Thyroid and gonadotropin axes were most commonly affected and deficiency of at least 1 axis was found in 82.4% patients in the acute phase and 59.3% in the chronic phase. Thyroid axis deficiency had a negative impact on prognosis in post-TBI patients.

Comparative Study
Sacroiliac joint degeneration after lumbar or lumbosacral fusion surgery - a comparative study of the number of fused segments and sacral fusion.
In this study, we aimed to investigate whether multi-segment fusion or fusion-to-sacrum increases sacroiliac joint (SIJ) pathology compared with single-segment fusion or a non-fused sacrum. ⋯ SIJ degeneration occurs independent of the number of fused segments or sacrum involvement.
