Video summary
The video discusses the spectrum of pathologies affecting tendons, emphasizing that these conditions are not limited to the wrist but can occur wherever tendons are present in the body. The progression of tendon issues typically begins with either tendinosis or tenosynovitis and can advance to a complete tendon tear. Understanding where a patient falls within this spectrum is crucial for determining the appropriate management strategy, as the treatment approach varies significantly depending on whether the condition is still in its early stages or has progressed to a structural failure of the tendon.
Tendinosis is identified by an increased signal intensity within the tendon itself, which indicates a disruption in the normal structure of the tissue. Normally, tendons appear dark on imaging due to their dense collagen fibers, but in cases of tendinosis, there is a misorganization or loosening of these fibers, leading to visible bright spots that signify degeneration. When this degenerative process is accompanied by fluid accumulation within the surrounding tendon sheath, the condition evolves into tenosynovitis, which involves inflammation of the sheath along with the underlying tendon issues.
The most severe stage in this progression is a tendon tear, where the continuity of the tendon is broken, leaving distinct fragments separated from one another. In such cases, there is often concurrent synovitis within the tendon sheath alongside the physical rupture of the tendon fibers. Imaging plays a vital role in distinguishing between these stages to ensure accurate diagnosis, as it allows medical professionals to determine if the pathology is limited to degeneration and inflammation or if it has reached the point of a full tear requiring more invasive intervention.
The clinical importance of differentiating between these conditions lies directly in the treatment plan required for patient recovery. If the diagnosis remains at the stage of tendinosis or tenosynovitis, the standard approach is conservative management, which may include rest, physical therapy, and anti-inflammatory measures to allow the tissue to heal without surgery. However, once a tendon tear is confirmed, the focus shifts to restoring functionality, which might necessitate surgical repair or other advanced interventions to reconnect the torn ends of the tendon and prevent permanent loss of movement.

>> Now, if we talk about pathologies to the
tendon, right? This is not something
which is specific to the wrist. It is
something which is specific to a
wherever you see tendons. So, the
spectrum usually starts with tendinosis
or tenosynovitis and you can have a
tendon tear. So, this is the actually
the spectrum which you see once you're
talking about the tendon pathologies.
So, tendinosis means when you see just
increased signal within the tendon. So,
just see the other tendons. See the
cursor is pointing to the other tendons
and you can see how dark all the tendons
look like. So, normally the tendons
should look pretty dark. However, in
this case this tendon shows some
increased signal within. So, this is
what is labeled as tendinosis when there
is misorganization of the collagen
fibers or there is loosening of the
collagen fibers. So, we start to get
some increased signal. So, that is what
we label as tendinosis.
When it is associated with tendon sheath
fluid, as you can see over here, you see
some tendon sheath fluid, it becomes
tenosynovitis.
And sometimes the tendon may get torn.
So, you can see one bit of tendon here
and one bit of tendon here. So, there is
a tear within the tendon, right? Along
with obviously synovitis along the
tendon sheath. So, this is further gone
up to the stage of tear. So, when we are
doing a particular imaging, we are
trying to figure out whether the
pathology belongs to which of the
categories, whether we are still at
tendinosis or tenosynovitis
or are we progressed to tendon tear.
Why is it important? Because if it is
still tendinosis and tenosynovitis, we
are going to manage it conservatively.
But it if it has gone torn, we might
need to think what we need to do to get
back the patient functionality.
