Pre- and Postseason Dynamic Ultrasound Evaluation of the Pitching Elbow.

Purpose: To use ultrasound imaging to document changes over time (i.e., preseason v postseason) in the pitching elbow of high school baseball pitchers.

Can femoral rotation be localized and quantified using standard CT measures?

Background: The terms "femoral anteversion" and "femoral torsion" have often been used interchangeably in the orthopaedic literature, yet they represent distinct anatomical entities. Anteversion refers to anterior tilt of the femoral neck, whereas torsion describes rotation of the femoral shaft. Together, these and other transverse plane differences describe what may be considered rotational deformities of the femur.

Video: Common upper extremity injections utilizing musculoskeletal ultrasound.

Objective: The purpose of this video article is to demonstrate the use of ultrasound for upper extremity musculoskeletal injections, covering general guidelines, preprocedure planning, needle selection, and basic technique. Several different upper-extremity injections are shown, including joint injections and aspirations, tendon sheath and bursal injections, and percutaneous treatment of calcific tendinitis.

Conclusion: Musculoskeletal ultrasound is well suited for imaging-guided injections of the upper extremities.
