Calcinosis of chronic renal failure

Calcinosis of chronic renal failure is a rare cause of soft tissue calcifications in hemodialysis patients with chronic renal failure. This condition is characterized by the deposition of calcium phosphate crystals in the periarticular soft tissues, resulting in large calcified masses. Terminol...

Age related macular degeneration

Age-related macular degeneration (AMD) is an eye disease that affects central vision. It occurs when aging causes damage to the macula. The macula is responsible for fine detailed vision also known as central vision.

Talar tilt

Talar tilt is a measurement of the angle between the talus and the distal tibia, used in the assessment of ankle instability and ankle osteoarthritis (OA). Usage Talar tilt is an important measurement in the assessment of ankle osteoarthritis. It is measured as part of the Kellgren and Lawrenc...

Medial cuneiform-fifth metatarsal height

Medial cuneiform-fifth metatarsal height is the distance between the most inferior part of the medial cuneiform and the most inferior part of the base of the 5th metatarsal and is used to evaluate the height and integrity of the medial vertical arch 1. Usage Medial cuneiform-fifth metatarsal h...

Autoimmune hemolytic anemia

Autoimmune hemolytic anemia is a group of hemolytic anemias characterized by an antibody response to red blood cells. It can present as acute or chronic anemia. It can be idiopathic or can occur with other disorders. Several types have been described: warm-antibody type anemia (WAIHA)  cold-a...

The Nunley-Vertullo classification is one of several classification systems used for the categorization of Lisfranc injuries. It is based on clinical, x-ray and bone scan findings and also associates the stages with management options or recommendations regarding those injuries 1-3. Usage The ...

Lateral tibiotalar distance

Lateral tibiotalar distance is a measurement on an ankle anterior drawer lateral view to assess for ankle instability.  Measurement On an ankle anterior drawer lateral view (typically performed using a Telos device 2-4), the distance between the posterior tip of the distal tibial articular sur...

Post-traumatic pseudolipoma

Post-traumatic pseudolipomas, also known as post-traumatic lipohypertrophy, are prominent increases in the volume of subcutaneous adipose tissue or even benign tumors arising at the location of a preceding blunt soft tissue trauma 1. Clinical presentation Focal palpable mass, not tender and wi...

Posterior tibial line

The posterior tibial line is drawn along the posterior aspect of the distal tibial shaft on a lateral ankle x-ray and can be used to assess the sagittal alignment of the talus when comparing side-to-side and/or calculate the posterior tibial line-talar ratio 1,2.

AP Meary's angle

AP Meary's angle or AP talus-first metatarsal angle is used to assess for midfoot abduction/adduction in pes planus and pes cavus to assist with pre-operative planning 1.  Measurement On a weight-bearing AP foot radiograph, a line is drawn down the longitudinal axis of the first metatarsal to ...

Friedman line

The Friedman or scapular line can be used to determine glenoid version and glenoid bone loss 4. Glenoid version angle measured by the Friedman method has better inter-reader reliability than the scapular body method 2.  Measurement The Friedman line is drawn along the long axis of the scapula ...

Fourth-fifth intermetatarsal angle

The fourth-fifth intermetatarsal angle is used to assess for a bunionette deformity. It should not be confused with the first intermetatarsal angle, used to assess for hallux valgus deformity.  Measurement The 4-5 intermetatarsal angle is formed between the long axis of the fourth and fifth me...

Broden's view

The Broden's view (or Broden view) is a specialized projection that accurately 1 examines the large posterior calcaneal facet and the subtalar joint 2. As technology advances, computed tomography (CT) has widely been used to better visualize and characterize fragment displacements and fracture ...

Comma sign of subscapularis tear

The comma sign of subscapularis tear was first described on arthroscopy but recognized later on MRI. The comma sign represents a full thickness partial width superior subscapularis tear along with torn superior glenohumeral and coracohumeral ligament insertional fibers vertically retracted via a...
