Imaging Review of Different Subchondral Insufficiency Fractures.

ABSTRACT: Subchondral fractures are a common cause of joint pain that may ultimately lead to articular collapse and the need for arthroplasty. This type of fracture has been reported at multiple joints throughout the body. While clinical and radiographic resolution can be achieved, progressive bone collapse can occur and lead to a variety of complications. Understanding the pertinent imaging findings can aid in the early evaluation of subchondral fractures and in the prevention of their associated complications.

Radiographic Evaluation of Elbow Fractures.

Fractures and dislocations of the elbow are a common cause of emergency department visits each year. Radiography remains the bedrock of an initial injury assessment, and recognition of distinctive injury patterns based on fracture location, morphology, and severity, guides optimal clinical decision-making. This article reviews basic elbow anatomy, frequently seen fractures and injury patterns, and highlights how these findings influence surgical planning and patient management.

MRI findings of chronic distal tendon biceps reconstruction and associated post-operative findings.

Rupture of the distal biceps tendon is becoming increasingly diagnosed due to an active aging population and an increase in diagnostic imaging opportunities. While physical exam may help in diagnosis, magnetic resonance imaging (MRI) is particularly useful in evaluating chronic rupture. Although partial tears can be managed conservatively, the gold standard treatment for a chronic distal biceps tear is anatomic reinsertion with additional use of an allograft or autograft. No study has highlighted the normal appearance and postsurgical complications seen on MRI associated with allograft or autograft usage. Clinicians and radiologists may be unaware of the normal and abnormal post-operative imaging findings and their clinical relevance. The purpose of this manuscript is to discuss the epidemiology, clinical presentation, and preoperative MRI findings of distal biceps ruptures necessitating reconstruction, to explain distal biceps tendon surgical reconstruction technique with allograft or autograft usage, to display the normal and abnormal post-operative MRI findings, and to review the clinical outcomes associated with the procedure.
