parrot beak tear

(redirected from Flap Tear)
The most common meniscal tear, a type of radial tear which begins at the free (inner) edge like other radial tears, but then curves into a longitudinal orientation—similar to longitudinal meniscal tears—as the tear extends toward the meniscal periphery. As the tear is traced on sequential MR images, it moves closer to the outer portion of the meniscus and then remains equidistant from the outer meniscal margin on subsequent images, as seen on longitudinal tears

[4] reported five cases of spontaneous recurrent hemarthrosis of the knee in which a degenerative flap tear of the posterior horn of lateral meniscus was revealed with arthroscopic examination.
Mucosal flap tear was the most common complication encountered after endoscopic septoplasty which occurred in 4(7%) and was due to sharp spur, synechaiem in 3(5.2%), hemorrhage seen in 1(1.7%), septal perforation in 1(1.7%).
Helpful clues in these cases include non-visualization of the posterior horn of the meniscus, the appearance of a larger anterior horn than posterior horn, or an anterior horn taller than 6mm .Flap Tears: A flap tear or a displaced flap tear is a term that is used often to describe a short-segment, horizontal meniscal tear with fragments either displaced into the notch or into the superior or inferior gutters.
Out of 36 grade-3 medial meniscal tears, 9 (25%) tears were classified as horizontal tears, 4(11.1%) as vertical, and 15(41.6%) complex tears, 3(8.3%)-bucket handle, 3(8.3%) radial tear and 2(5.5%) as flap tear (Fig.
It explains the normal LASIK procedure, then details complications like loss of suction, air bubbles in the anterior chamber, buttonholed flaps and vertical gas breakthrough, opaque bubble layer, free flaps, flap tears, incomplete flaps, irregular flaps, epithelial defects, thin and thick flaps, decentered flaps, subconjunctival hemorrhage and bleeding, and the management of postoperative complications, with discussion of etiology, incidence, and prevention.
Among the meniscal injuries the various patterns of tears that we came across were horizontal tears, bucket handle tears, radial tears, flap tears and complex tears.
Flap tears (Figure 7) produce U or V shape breaks with the apex of the flap pulled into the vitreous cavity but still attached at the anterior border of the tear.
