Alpha Angle Measurements in Healthy Adult Volunteers Vary Depending on the MRI Plane Acquisition Used.

Background: It has been shown that cam deformities are located at a more anterosuperior location than was previously described.

Purpose: To establish, in a large group of asymptomatic participants, the normative range of the alpha angle in the anterosuperior location in both the oblique axial and radial views of magnetic resonance imaging (MRI).

Study Design: Cross-sectional study; Level of evidence, 3.

Osseointegration of Fitmore stem in total hip arthroplasty.

Currently, an increasing number of younger patients undergo total hip arthroplasty surgery. This has led to a minimal invasive approach and the use of short, bone preserving, femoral stems. In this study, we sought to evaluate osseointegration of the Fitmore stem (Zimmer, Inc; Warsaw, IN) during the first 12 mo after surgery, which reflects the biological phenomenon of osseointegration with radiographic evaluation and bone densitometry (dual-energy X-ray absorptiometry).

Early diagnosis of vertebral fractures.

Vertebral fractures are a common clinical entity, caused by trauma or related to osteoporosis (benign). Their recognition is especially important in the post-menopausal female population but also important is their differentiation from pathological (malignant) fractures (1). A vertebral fracture is evidenced by vertebral body deformity or reduction in vertebral body height beyond a certain threshold value in the absence of bone discontinuity.
