what is a intrasubstance tear
Interstitial tears (Figure 6), also known as intrasubstance tears or intramuscular cysts, can occur in isolation within the tendon without articular-or bursal-sided extension, or they can also occur in combination with either articular-or bursal-sided partial thickness tears.eyond the location of the partial thickness tear, describing the extent of the tear is also important. Ruotolo et al showed that the mean thickness of the supraspinatus tendon ranges from 11.6 mm (anteriorly) to 12.1 mm (midtendon). (Enlarge Image). Figure 2.
