Biomechanical Design, Additive Manufacturing, and Proof-of-Concept Evaluation of a 3D-Printed Transradial Prosthesis with a Manual Ratchet-Type Locking Mechanism

Background/Objectives: Upper-limb loss represents a critical clinical and socioeconomic challenge globally. While myoelectric devices offer multi-articulated grasping, their high cost restricts access in low-resource settings. This work presents the preliminary biomechanical desi...

Jugulotympanic paraganglioma, preoperative embolization, and transmastoid retrolabyrinthine approach: Two-dimensional operative video

Background: Jugulotympanic paraganglioma (JTP), also known as glomus jugulare tumor, is a neuroendocrine neoplasm. Although it represents <0.5% of head-and-neck tumors, it demonstrates significant local aggressiveness due to its tendency to infiltrate bone, vascular structures, a...
