Role of preoperative posterior tilt on the outcomes of internal fixation of non-displaced femoral neck fractures: A systematic review and meta-analysis.

Introduction: There has been an increased interest in the role of preoperative posterior tilt, as measured on lateral radiographs, on the outcomes of internal fixation of non-displaced femoral neck fractures (FNF). The goal was to assess the available evidence for this in the literature.

Patients And Methods: PRISMA guidelines were followed.

Treatment of coracoid process fractures: a systematic review.

Introduction: The coracoid process is a small hook-shaped feature on the scapula and a key structure of the superior shoulder suspensory complex (SSSC). Fractures of the coracoid are rare. Therefore, no consensus exists regarding treatment of coracoid process fractures.

Scheuermann disease: evaluation of radiological criteria and population prevalence.

Study Design: Observational population-based study.

Objective: To determine the prevalence of radiographical Scheuermann disease in a Dutch population and evaluate the consistency of diagnostic criteria.

Summary Of Background Data: Scheuermann disease is a form of osteochondrosis characterized by increased posterior rounding of the thoracic spine with structural vertebral deformity.

Multi-functionality of computer-aided quantitative vertebral fracture morphometry analyses.

Osteoporotic vertebral fractures are an increasingly active area of research. Oftentimes assessments are performed by software-assisted quantitative morphometry. Here, we will discuss multi-functionality of these data for research purposes.

The VEX-test for myocardial scintigraphy with thallium-201 and sestamibi: effect on abdominal background activity.

Unlabelled: High abdominal background activity of 99mTc-sestamibi may interfere with the diagnosis in studies in which a coronary vasodilator is used; supplemental dynamic exercise might reduce this problem.

Methods: Clinical and angiographic determinants of subdiaphragmatic-to-myocardial activity ratios were measured on immediate poststress left anterior oblique images and on corresponding tomographic studies 1 hr after injection in 600 sestamibi studies. Similar measurements were made in 550 historic controls with planar 201Tl imaging.
