RTC tears

Question 1

Full thickness RC tear: what is a direct sign?

Answer 1

A direct sign is a defect seen over the full thickness of the tendon, communication with the articular cartilage and bursa, can have a complete rupture from GT, usually visualize volume loss or loss of bulk substance and no bursal herniation into the void of tear

Question 2

Full thickness RC tear: what is a indirect sign?

Answer 2

Herniation of Deltoid and Peri busal fat into the tear. 1. Bursal effusion 2. naked cartilage or naked tuberosity sign 3. cartilage interface sign

Question 3

Naked Tuberosity sign-an indirect sign

Answer 3

A full thickness tear or rupture of the SS with retraction from the greater tub thus leaving the bone uncovered. There is not fluid interface associated with this sign

Question 4

Cartilage interface sign: indirect RC tear

Answer 4

Defined as a distince, well defined hyperechoic reflection of ultrasound beam at the interface between the fluid and the hyaline cartilage. A hyper reflection of the cartilage when the US beam is perpendicular to it due to the presenece of edema. Fluid with occurrence of full thickness tear, heighly reliable sign.

Question 5

RTC Progression: Tendinosis

Answer 5

Progression is a teninosis with no tears, tendinosis with partial tears and tendinosis with full thickness tears

Question 6

RTC progression: Direct Sign

Answer 6

Full thickness direct sign is bursal and articular side, volume loss, grt tube rutputure, bursal and articular side, volume loss and grt tub ruputure

Question 7

RTC progression: Indirect Sign

Answer 7

Indirect sign or RTC tear is a delta or bursa herniation, budrsal effusion, naked tuberosity, no fluid, cantilage interface fluid and edema
