Total Talar Replacement: Surgical Technique.
JBJS Essent Surg Tech
April 2023
Department of Orthopaedic Surgery, Nara Medical University, Kashihara, Nara, Japan.
Article Synopsis
- Total talar replacement is a reconstructive surgical procedure aimed at treating severe osteonecrosis of the talus, using a custom-made alumina ceramic implant to restore mobility after injuries or various diseases.* -
- The surgery involves removing the damaged talus through a series of osteotomies and ligament dissections before implanting the new talar prosthesis, ensuring proper fit and stability.* -
- Alumina ceramic implants are favored over stainless steel due to their better compatibility with articular cartilage and ability to maintain ankle mobility post-surgery, according to studies involving animal models.*
Intermittent At-Home Suctioning of Esophageal Content for Prevention of Recurrent Aspiration Pneumonia in 4 Dogs with Megaesophagus.
J Vet Intern Med
September 2016
Department of Clinical Sciences, College of Veterinary Medicine, North Carolina State University, Raleigh, NC.
Background: Megaesophagus carries a poor to guarded prognosis due to death from aspiration pneumonia. Options for medical management of regurgitation are limited to strategic oral or gastrostomy tube feeding.
Objectives: To describe the use and efficacy of intermittent esophageal suctioning to prevent regurgitation and associated episodes of aspiration pneumonia in dogs with megaesophagus.
Outcomes of Air Injection Within 2 mm Inside a Deep Trephination for Deep Anterior Lamellar Keratoplasty in Eyes With Keratoconus.
Am J Ophthalmol
April 2016
Department of Ophthalmology, Rabin Medical Center, Petah Tikva, Israel; Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.
Purpose: To evaluate the outcomes of a new technique for deep anterior lamellar keratoplasty (DALK) employing the injection of air up to 2 mm inside a deep trephination (intended within 100 μm from the endothelial surface) obtained with a guarded trephine set by means of anterior segment optical coherence tomography (AS OCT).
Design: Retrospective, noncomparative, interventional case series.
Methods: The success rate and learning curve of pneumatic dissection in one clinical practice were analyzed in nonscarred keratoconic eyes undergoing a standardized DALK including 9-mm trephination intended to a depth within 100 μm from the endothelial surface, based on the thinnest AS OCT measurement at this site; and injection of air through a cannula advanced 1-2 mm centripetally from the bottom of the trephination.
Active aspiration of suprachoroidal hemorrhage using a guarded needle.
Ophthalmic Surg Lasers Imaging Retina
September 2014
Background And Objective: To describe a novel technique using a guarded needle to drain suprachoroidal hemorrhage.
Patients And Methods: A guarded needle is used to drain suprachoroidal hemorrhage under direct microscope visualization. A scleral buckling sleeve is used to create a guarded 26-gauge needle to avoid over-penetration of the needle beyond the suprachoroidal space.
