Have
you had a joint problem and been told that you have "degeneration" or "degenerative
changes"? What exactly does
this mean? Is this something that can be
fixed? Let's take a closer look at two
common types of degenerative changes
and some potential management strategies that can be employed.
1. Degenerative
Joint Disease (DJD) is also
known as osteoarthritis, and is the most common form of arthritis. Weight-bearing joints such as the hips and
knees are most commonly affected, but DJD
can affect any area of the body, including the hands, neck, and low back.
Most joints in our
body have smooth cartilage surfaces that glide against each other, which allow
two or more opposing bones to move freely and perform a specific set of
movements. A joint becomes "degenerated" or arthritic when
there is wearing down of these cartilage surfaces, and a change in the
composition of the bone underneath the cartilage occurs. An arthritic joint does not mechanically
function like it is supposed to. This
may result in a number of symptoms including:
muscle tightness and weakness, joint pain and stiffness, decreased ranges
of motion, creaking in the joints, swelling, inflammation, and joint thickening
(i.e. finger nodules, bunions).
2.
Degenerative Disc
Disease
(DDD) specifically affects the
spinal discs between each vertebrae and is also considered an arthritic
disorder. Spinal discs allow for some
movement between vertebrae, and they also absorb compressive, tensile, and
shearing loads with everyday activities.
The centre of the disc, called the nucleus pulposis, is jelly-like and
mostly made up of water. The outside of
the disc, called the annulus fibrosis,
is tough and thick and contains the nucleus
pulposis. Over time, the water
content of the spinal disc diminishes, causing it to dry out and become
fibrotic (tough and brittle). As the
disc becomes fibrotic it can develop tears.
This breakdown can result in disc herniations, the development of bony
spurs, and sciatica.
Risk
factors/causes for DJD and DDD are typically multi-factorial,
meaning that there is usually no single cause, but rather a combination of
several different factors. These risk
factors/causes may include but are not limited to: advancing age, genetic
predisposition, mechanical overload from occupational and recreational
activities, direct injury to the affected region, cigarette smoking, lack of
exercise, and being overweight or obese.
Degenerative changes
can result in debilitating symptoms for some individuals and can be managed a
number of ways. Maintaining an ideal body
weight through a healthy diet and regular exercise consisting of strength, flexibility, and endurance
training can reduce the risk of pain and subsequent disability. Treatment from licensed health professionals
who utilize manual mobilization therapies, soft tissue therapy, electrotherapy,
acupuncture, exercise and rehabilitation strategies can also significantly help
to decrease pain by restoring normal muscle and joint motion, and promote
healing of arthritic or injured areas.
In
the event that you suffer from degenerative
joint changes, you should contact a licensed health professional who deals in
the diagnosis and treatment of these conditions. For more information, visit www.nhwc.ca.
