What is delamination of cartilage?
Chondral delamination is a form of cartilage injury and refers to the separation of the articular cartilage from the underlying subchondral bone at the tidemark. It may or may not be associated with chondral fissure. Focal delamination is sometimes termed a carpet lesion 6.
What causes chondral delamination?
Mechanism. Often associated with twisting or traumatic shearing stress to the cartilage occurring parallel to the joint surface along the surface of the tidemark (usually concentrated at the junction of non-calcified and calcified cartilage 7).
What is frayed cartilage?
Focal damage (injury to a small, specific region) to cartilage can range from small tears with fraying to complete detachment of a piece of cartilage leaving the underlying bone exposed. For instance, the term chondromalacia refers to softening or fraying of the cartilage with minor damage.
What is chondral delamination knee?
Chondral delamination (Figure 1) is defined as the separation of articular cartilage from the underlying subchondral bone.
What is the meaning of delamination?
separation into constituent layers
Medical Definition of delamination 1 : separation into constituent layers. 2 : gastrulation in which the endoderm is split off as a layer from the inner surface of the blastoderm and the archenteron is represented by the space between this endoderm and the yolk mass.
What is chondral delamination hip?
Delamination is a characteristic chondral lesion of the hip (wave sign), in which the cartilage detaches from the subchondral bone leading to a ‘bag lesion’ and chondral flaps.
Can damaged cartilage heal itself?
Q: Can cartilage repair itself? A: Though it is made of cells and tissues, cartilage cannot repair itself due to the lack of blood vessels and enough blood supply to create and duplicate new cells.
What does delamination of a tendon mean?
Tendon delamination is the process of tearing where there is a longitudinal split and longitudinal separation of tendon fibers. While it typically occurs with tearing it may also be present with tendinopathic changes. It is typically observed in the rotator cuff.
What is Chondrolabral separation?
Chondrolabral separation refers to a form of chondrolabral injury, where the acetabular labrum is separated from the adjacent cartilage at the articular margin.
What is severe Chondrosis?
Chondrosis is the cartilage breakdown of the soft connective tissues in your joints. It happens due to excessive use, damage, and age factor. Commonly regarded as osteoarthritis, it usually attacks knees, hands, hips, neck, and lower backbone.
What does delamination mean on a MRI?
What is delamination of the rotator cuff?
A delaminated rotator cuff tear is a form of degeneration within the tendon; it generally refers to a horizontal tear occurring between rotator cuff layers [11,21-23]. Literature has various definitions of a delaminated rotator cuff tear.
What is a delaminated articular cartilage?
Chondral delamination is the separation of the articular cartilage from the underlying subchondral bone at the tidemark . These injuries have been reported as the result of shearing stress that is concentrated at the junction of the noncalcified and calcified cartilage [1–3].
What is a delaminating tear of the posterior cruciate ligament?
Delaminating tears, or split tears, of the posterior cruciate ligament (Figures 33-35) have been documented in the literature, manifesting as increased linear signal intensity within the ligament.
What is delamination of composite materials?
Delamination is a well-known pattern of failure in composite material, related typically to the presence of weak adhesions between layers within that material, such as the failure of weak fiber polymers that are located between sheets of plastic.
