Editorial Commentary: There's More Meat on That Bone! Labral Hypertrophy Normalizes Femoral Head Coverage in Dysplastic Hips.

The size of the acetabular labrum has been shown to be larger in patients with acetabular hip dysplasia and smaller in patients with acetabular overcoverage. Compensatory morphologic changes to the acetabular labrum are potentially useful as an imaging biomarker of hip stability, and with additional future outcomes investigation, imaging measures may be used to guide the type and extent of hip preservation surgery.

Lateral acetabular labral length is inversely related to acetabular coverage as measured by lateral center edge angle of Wiberg.

Patients with developmental dysplasia of the hip often have compensatory labral hypertrophy, which presumably lends stability to an unstable joint. Conversely, patients with acetabular overcoverage may have small or ossified labra. The purpose of this study is to explore the interaction of labral length with the degree of acetabular hip coverage.

Knee pain · no popping · no previous trauma · Dx?

A 36-year-old man sought care at our family medicine clinic for knee pain that he'd had for the past year. He denied any previous injury or trauma to the knee. The pain affected the posterolateral left knee and was aggravated by squatting and deep flexion.

Introduction of a virtual workstation into radiology medical student education.

OBJECTIVE. This article describes the creation of a virtual workstation for use by medical students and implementation of that workstation in the reading room. CONCLUSION.

Brief report: airways abnormalities and rheumatoid arthritis-related autoantibodies in subjects without arthritis: early injury or initiating site of autoimmunity?

Objective: To evaluate the presence of pulmonary abnormalities in rheumatoid arthritis (RA)-related autoantibody-positive subjects without inflammatory arthritis.

Methods: Forty-two subjects who did not have inflammatory arthritis but were positive for anti-cyclic citrullinated peptide antibodies and/or ≥2 rheumatoid factor isotypes (a profile that is 96% specific for RA), 15 autoantibody-negative controls, and 12 patients with established seropositive early RA (<1-year duration) underwent spirometry and high-resolution computed tomography (HRCT) lung imaging.

Results: The median age of autoantibody-positive subjects was 54 years, 52% were female, and 38% were ever-smokers; these characteristics were not significantly different from those of autoantibody-negative control subjects.

Normal anatomy and anatomical variants of the elbow.

This article provides a brief review of the normal osseous, ligamentous, muscular, and neurovascular imaging anatomy of the elbow. Special attention is paid to the normal structures that may simulate pathology, as well as anatomical variants that may lead to pathology. This review will help clarify distinctions between normal anatomy and abnormal anatomy, as well as elucidate pathological consequences of a seemingly normal structure.

Shoulder MR arthrography of the posterior labrocapsular complex in overhead throwers with pathologic internal impingement and internal rotation deficit.

Purpose: To determine if overhead-throwing athletes with internal impingement pain and internal rotation deficit have thickening of the posterior inferior labrocapsular complex on MR arthrogram images.

Materials And Methods: This study was approved and a waiver of consent granted by our institutional review board. Twenty-six overhead-throwing athletes with internal impingement pain and internal rotation deficit, and 26 controls who had undergone MR arthrograms, were retrospectively examined.
