BACKGROUND: Previous studies on thoracolumbar fractures with neurological symptoms have focused on how to achieve satisfactory fracture reduction, adequate nerve decompression, and stable spinal alignment. With the development of the minimally invasive spine surgery technique, achieving satisfactory treatment results and reducing iatrogenic trauma at the same time has become a new goal of spinal surgery. This research used percutaneous transpedicular screw distraction to partially reduce the fractured vertebrae, followed by completing nerve decompression and reducing residual displacement bone fragments with the assistance of the unilateral biportal endoscopic (UBE) technique to achieve full protection of bone-ligament tissue and obtain good clinical efficacy...

Injectable antibacterial hydrogels have attracted considerable attention in wound management. However, the development of injectable hydrogels with excellent antibacterial activity, good biocompatibility, and strong tissue adhesion remains a challenge. In this study, an antibacterial tissue-adhesive hydrogel was developed based on a catalyst-free o-phthalaldehyde (OPA)/amine reaction by simply mixing OPA-terminated four-arm poly(ethylene glycol) (4aPEG-OPA) and ε-poly-l-lysine (ε-PLL) solutions...

INDICATIONS: The Scheker prosthesis is intended to replace the DRUJ in patients with rheumatoid, degenerative, or posttraumatic arthritis of the sigmoid notch and/or ulnar head, or in cases of gross instability of the DRUJ. Moreover, a Scheker prosthesis can be used to treat failed salvage procedures, such as the Sauvé-Kapandji procedure, ulnar head resection, and ulnar head arthroplasty...

The aim of this report is to discuss malposition of the resorbable sheet in medial orbital wall fractures and how to prevent this problem. After making an incision through the skin and orbicularis oculi muscle, a skin-muscle flap was elevated just superficial to the orbital septum, extending to the arcus marginalis. Dissection was extended just below the anterior lacrimal crest to increase the exposure. Fracture site in medial orbital wall was visualized. A resorbable sheet (poly-l-lactide, d-lactide sheet, 0...

During microvascular decompression (MVD) for trigeminal neuralgia (TGN), the mastoid emissary veins (MEV) are routinely sacrificed using the suboccipital retrosigmoid approach. The technical nuances when the MEV is an important collateral venous pathway for the obstructive internal jugular vein (IJV) have not been described thus far. Herein, we demonstrate for the first time a modified surgical technique for MVD to preserve the MEV. A 62-year-old man with a 10-year history of TGN refractory to carbamazepine was referred to our hospital for MVD...

BACKGROUND: Azygos vein aneurysms are rare and asymptomatic in many cases.

ESGE suggests conventional endoscopic submucosal dissection (ESD; marking and mucosal incision followed by circumferential incision and stepwise submucosal dissection) for most esophageal and gastric lesions. ESGE suggests tunneling ESD for esophageal lesions involving more than two-thirds of the esophageal circumference. ESGE recommends the pocket-creation method for colorectal ESD, at least if traction devices are not used. The use of dedicated ESD knives with size adequate to the location/thickness of the gastrointestinal wall is recommended...
