Gastrojejunostomy junction perforation resulting from Dobhoff tube insertion in a patient with a history of Roux-en-Y surgery: a case report.

Background: Gastrojejunostomy junction perforation is a rare yet critical complication associated with enteral tube placement, presenting unique challenges in patients with a history of Roux-en-Y gastric bypass surgery.

Case Presentation: A 63-year-old white female with a complex medical history, including heart failure, atrial fibrillation, stage 4 chronic kidney disease, and prior Roux-en-Y gastric bypass surgery in 2015, experienced a significant decline in her health. She was discharged to a skilled nursing facility after a fall but deteriorated rapidly in the 2 weeks before admission.

Bilateral dual iliac screw pelvic fixation for adult spinal deformity: a case report of a superior gluteal artery pseudoaneurysm secondary to aberrant iliac screw trajectory.

Purpose: To present a case of a pseudoaneurysm of a branch of the left superior gluteal artery (SGA) secondary to lateral wall perforation from an iliac screw and its subsequent evaluation and management.

Methods: Case report.

Results: A 67-year-old female with a history of degenerative flatback and scoliosis and pathological fractures of T12 and L1 secondary to osteodisciitis underwent a single0stage L5-S1 ALIF and T9-pelvis posterior instrumented fusion with bilateral dual iliac screw fixation, revision T11-S1 decompression, and T12 and L1 irrigation and debridement and partial corpectomies.

Feasibility of a Novel Fluoroscopic Trainer for the Orthopaedic Trainee.

Objective: We sought to create a novel method of teaching orthopedic trainees to efficiently obtain intraoperative radiographs using nonfluoroscopic digital cameras. Specifically, teaching them to make minor, uniplanar, adjustments while limiting the number of fluoroscopy images obtained during placement of a guidewire "start-point," for intramedullary nailing.

Design: Prospective cohort study including medical students from 2 academic centers.

3D imaging of the vagus nerve fascicular anatomy with cryo-imaging and UV excitation.

Vagus nerve stimulation (VNS) is a method to treat drug-resistant epilepsy and depression, but therapeutic outcomes are often not ideal. Newer electrode designs such as intra-fascicular electrodes offer potential improvements in reducing off-target effects but require a detailed understanding of the fascicular anatomy of the vagus nerve. We have adapted a section-and-image technique, cryo-imaging, with UV excitation to visualize fascicles along the length of the vagus nerve.
