Glenoid Radius of Curvature and Humeral Head Volume Are Associated With Postoperative Dislocation After Arthroscopic Bankart Repair.

Purpose: To measure bony morphologic parameters and identify their association with arthroscopic Bankart repair failure.

Methods: This was a retrospective comparative study. The inclusion criteria were primary arthroscopic Bankart repair, no prior shoulder surgery, traumatic cause, and had a Bankart (soft tissue and bony) lesion evident on magnetic resonance imaging (MRI).

Labral Morphology and Number of Preoperative Dislocations Are Associated With Recurrent Instability After Arthroscopic Bankart Repair.

Purpose: To develop a method to measure capsule and labral volume on preoperative magnetic resonance imaging to predict surgical failure after primary Bankart repair.

Methods: A retrospective case-control study was conducted on patients undergoing primary anterior arthroscopic shoulder stabilization. Surgical failure was defined as a recurrent dislocation event.

Subchondral insufficiency fracture of the knee: A recognizable associated soft tissue edema pattern and a similar distribution among men and women.

Objective: Primary: to describe the presence and pattern of soft tissue edema in subchondral insufficiency fractures of the knee (SIFK). Secondary: to investigate the gender distribution and identify factors associated with disease progression.

Methods: MR images of 74 SIFKs in 74 patients were retrospectively reviewed for soft tissue edema presence and location, meniscal tears and extrusion and synovitis.

Correlation Between Cam-Type Femoroacetabular Impingement and Radiographic Osteitis Pubis.

A mechanistic link has been suggested between cam-type femoroacetabular impingement and increased stress on the symphysis pubis. This retrospective study was conducted to determine whether there is an increased prevalence of osteitis pubis, as evidenced by imaging, in patients with femoroacetabular impingement compared with age-matched control subjects. Search of a radiologic database of a large academic health institution for all patients with cam-type femoroacetabular impingement diagnosed by magnetic resonance imaging or magnetic resonance arthrogram between January 2000 and October 2013 identified 46 cases.

Molecular imaging: an innovative force in musculoskeletal radiology.

Objective: A review of the innovative role molecular imaging plays in musculoskeletal radiology is provided. Musculoskeletal molecular imaging is under development in four key areas: imaging the activity of osteoblasts and osteoclasts, imaging of molecular and cellular biomarkers of arthritic joint destruction, cellular imaging of osteomyelitis, and imaging generators of musculoskeletal pain.

Conclusion: Together, these applications suggest that next-generation musculoskeletal radiology will facilitate quantitative visualization of molecular and cellular biomarkers, an advancement that appeared futuristic just a decade ago.

The adoption of low-osmolar contrast agents in the United States: historical analysis of health policy and clinical practice.

Objective: In this historical analysis of low- and high-osmolar contrast agents, we outline the reasons for the price depreciation, speculate on motivation for universal adoption by many radiologists despite suboptimal reimbursement, and cast light on important shortcomings of economic analyses in the realm of health policy.

Conclusion: Early economic analyses regarding low-osmolar contrast agents concluded that universal adoption was not cost-effective. Over time, the price differential between low- and high-osmolar agents narrowed, yet reimbursement patterns lagged behind the narrowing price differential.

Intraluminal migration of surgical drains after transhiatal esophagogastrectomy: radiographic findings and clinical relevance.

Objective: The objectives of our study were to review our experience with a group of patients in whom contrast examinations after transhiatal esophagogastrectomy and gastric pull-through revealed intraluminal migration of a surgical drain and to describe the radiographic appearance and clinical relevance of this phenomenon.

Conclusion: Our findings indicate that intraluminal migration of a surgical drain after transhiatal esophagogastrectomy is an infrequent but serious phenomenon that hinders or prevents healing of an anastomotic leak. Radiologists should be aware of this phenomenon and should be able to recognize the findings of an intraluminal drain on contrast examinations.

Embolization of a Recurrent Type 2 Endoleak Using the Liquid Embolic n-Butyl Cyanoacrylate.

Endovascular aneurysm repair (EVAR) has become an accepted alternative to open aortic aneurysm repair. Endoleaks are one of the most common complications of EVAR and can result in aneurysm enlargement and rupture. When embolization of type 2 endoleaks is needed, a transarterial or translumbar approach may be used.
