Novel Screw Placement Method for Extremely Small Lumbar Pedicles in Scoliosis.

Consecutive case series. To propose a screw placement method in patients with extremely small lumbar pedicles (ESLPs) (<2 mm) to maintain screw density and correction power, without relying on the O-arm navigation system. In scoliosis surgery, ESLPs can hinder probe passage, resulting in exclusion or substitution of the pedicle screws with a hook.

Establishing a relationship using CT between facet distraction and clinical outcomes after ACDF.

Background Context: Anterior cervical discectomy and fusion (ACDF), the gold standard treatment for radiculopathy and myelopathy, has the potential risk of inducing facet-mediated pain through over-distraction. However, the relationship between the clinical outcomes and facet distraction after ACDF remains unclear.

Purpose: To measure facet distraction using computed tomography (CT) and compare the results with the clinical outcomes after ACDF.

Anesthetic Management of Upper Tracheal Cancer Resection and Reconstruction: A Case Report.

Tracheal tumor resection and reconstruction is the primary treatment for tracheal tumors. The trachea is the surgical site as well as an important channel to ensure ventilation and maintain oxygenation during surgery. In this report, we describe the successful management of an upper tracheal tumor in a 50-year-old patient.

Risk factor analysis of parenteral nutrition-associated cholestasis in extremely low birth weight infants.

Aim: Parenteral nutrition (PN) provides an alternative nutrition source for preterm infants who are intolerant of enteral nutrition. However, prolonged PN increases the risk of PN-associated cholestasis (PNAC). We conducted this study to determine the incidence and risk factors of PNAC in extremely low birth weight (ELBW) infants.
