Patellar fractures are characterized by injuries to the extensor and typically require surgical fixation. Among the methods used for fixation, the most common is the modified AO tension-band wiring technique. However, using this technique, implant migration occurs due to the lack of connections between the K-wires and the tension-band wire, which causes irritation and reduces fracture stability. Recently, new methods for tension-band wiring have been developed in which tension bands lock the K-wires through an attached "ring" to prevent migration...

BACKGROUND: Biliary strictures (BS) are a common complication of liver transplantation. The standard treatment is sequential insertion of increasing numbers of plastic stents by endoscopic retrograde cholangiopancreatography (ERCP). Despite high success rates, some strictures fail to resolve and require surgery as definitive treatment. GOALS: To identify predictors of response or failure of standard endoscopic treatment, allowing earlier referral to alternative modalities when needed and avoiding unnecessary procedures...

FDG PET/CT has high sensitivity and specificity for the detection of distant metastases from cutaneous melanoma. Imaging is recommended for patients with clinical suspicion of metastasis and should be considered for those with confirmed sentinel lymph node metastasis. Metastatic melanoma bears a poor prognosis. Only a complete resection improves survival, which explains the need to detect potentially unresectable disease, and most metastatic patients are ineligible for a curative surgical procedure. Here, FDG PET/CT demonstrated isolated bilateral adrenal metastases from melanoma of unknown primary...

Stimuli responsive hydrogels (SRHs) are attractive bio-scaffolds for tissue engineering. The structural similarity of SRHs to the extracellular matrix (ECM) of many tissues offers great advantages for a minimally invasive tissue repair. Among various potential applications of SRHs, cartilage regeneration has attracted significant attention. The repair of cartilage damage is challenging in orthopedics owing to its low repair capacity. Recent advances include development of injectable hydrogels to minimize invasive surgery with nanostructured features and rapid stimuli-responsive characteristics...

Hemolysis after percutaneous device closure of ventricular septal defect (VSD) is a rare complication that can be conservatively managed in the majority of cases. However, surgery or transcatheter occlusion may be necessary. Presently described is the successful treatment of hemolysis that developed after implantation of the Nit-Occlud Lê VSD coil, using the Amplatzer Duct Occluder II (ADO II) in a patient with aneurysmatic perimembranous VSD. Systolic murmur and symptoms immediately disappeared after the procedure...

OBJECTIVE: Transcatheter aortic valve replacement (TAVR) has been accepted as an alternative to surgery in high risk or inoperable patients with severe aortic stenosis (AS). Although transfemoral approach is the most often preferred means of access, in patients with severe ilio-femoral arteriopathy, other vascular access sites may be required. The aim of the present study was to report our experience with trans-subclavian approach for TAVR using different valve systems. METHODS: Among 273 patients undergoing TAVR between June 2011 and May 2016, 10 patients (mean age: 68...

BACKGROUND: The dimensions and shape of the forehead determine the esthetics of the upper third of the face. Korean young people consider a broad and smooth, rounded forehead more attractive. As a result, frontal augmentation becomes more popular in patients with dentofacial deformities. Various surgical procedures and materials have been used in frontal augmentation surgery, with associated advantages and disadvantages. Silicone is a good candidate for frontal augmentation. The author presents two cases of esthetic frontal augmentation with a prefabricated silicone implant in female patients with dentofacial deformities...

INTRODUCTION:  Deep brain stimulator (DBS) infections are a persistent problem for patients undergoing this procedure. They may require further surgery, treatment with antibiotics, or even removal of the device. To date, no consensus exists on the best practices to avoid DBS infections or what factors predispose patients to an eventual infection. The goal of this study was to examine several patient factors for association with DBS infection. METHODS:  A single-center, single-surgeon quality improvement database was queried...
