Short-term radiographic and clinical outcomes of patients treated with anatomic total shoulder arthroplasty using a modern-generation implant with a metal-backed glenoid component.

Background: A leading cause of anatomic total shoulder arthroplasty failure continues to be glenoid component loosening. Historically, metal-backed glenoids (MBGs) have shown decreased performance compared with polyethylene-backed glenoid (PEG) components. Previous studies have shown that MBG components have higher revision rates and shorter time to prosthetic failure compared with PEG components.

The Effect of Metal Instrumentation on Patient and Surgical Team Scatter Radiation Exposure Using Mini C-Arm in a Simulated Forearm Fracture Fixation Model.

Introduction: To our knowledge, no studies have studied the effect of metal instrumentation (MI) in the field of fluoroscopy regarding changes in the intensity, direction of scatter, and degree of radiation exposure to the patient and surgical team. The goal of this study was to determine whether the presence of MI increases scatter radiation exposure to the patient and surgical team when using a mini C-arm in the horizontal and vertical positions.

Methods: Four trials were conducted using a lamb limb specimen and a mini C-arm to simulate a forearm/wrist fracture fixation scenario.

Amyloidosis of the renal pelvis presenting as flank pain.

Amyloidosis is a rare disease defined by accumulation of extracellular amyloid systemically or within a specific organ. Localized amyloidosis of the genitourinary system is extremely rare, with the predominate location being the bladder. The imaging findings are often nonspecific and mimic urothelial carcinoma.

Acquired uterine arteriovenous fistula following dilatation and curettage: an uncommon cause of vaginal bleeding.

Dysfunctional uterine bleeding is a common presentation of women in the emergency department. We describe the case of a 33-year-old female who presented with intermittent spotting due to an acquired uterine AVF. The patient underwent a transvaginal pelvic ultrasound as well as a CT angiogram.

Technical innovation: digital tomosynthesis of the hip following intra-articular administration of contrast.

Objective: To demonstrate the clinical use of digital tomosynthesis in the depiction of labral and chondral pathology in the setting of post-operative CAM-type impingement of the hip following intra-articular administration of dilute iodinated contrast.

Materials And Methods: We present images from a 46 year-old African American female with suspected CAM-type femoroacetabular impingement (FAI) following percutaneous pinning of the right hip for slipped capital femoral epiphysis (SCFE).

Results: A partial tear of the labrum and clinically significant acetabular chondral abnormalities were demonstrated with the use of digital tomosynthesis with superb anatomic detail.

Biatrial Drainage of a Right-Sided Superior Vena Cava.

We report a case of chronic hypoxemia in a 62-year-old woman as a result of biatrial drainage of a right-sided superior vena cava. Radionuclide ventilation and perfusion imaging revealed significant increased radiotracer activity in the kidneys, bowel, and thyroid gland suggesting a right-to-left shunt which was confirmed by contrast enhanced CT of the chest. An anatomically correct right-sided SVC drained through two channels, the larger of which emptied into the roof of the left atrium and a smaller atretic portion feeding the right atrium.
