The most prominent symptom of hip arthritis is pain. Most
patients think that their hip is in the region of the buttocks
and are surprised to learn that true hip pain is most commonly
experienced in the groin. Groin pain of hip arthritis is sometimes misdiagnosed at first as a hernia or a “groin pull”. (There is no known medical diagnosis of, and no Wikipedia definition for “groin pull”, but strangely, patients frequently self-diagnose themselves with this “condition”). The pain can radiate down the
front of the thigh for a few inches as well. Occasionally
it goes all the way down the thigh to the knee (“referred
pain”). This is because the hip and knee have an overlapping
nerve supply. In fact, in some patients with hip disease,
knee pain may be the only symptom!
Back pain is even
more frequently confused with hip pain. Pain in the buttocks,
across the low back and down the back of the thigh usually
comes from the spine. It usually indicates a pinched nerve
in the lower spine. Patients with a pinched nerve will
also often have numbness or tingling in the leg. To complicate
matters, some patients with an arthritic hip may also have
a pinched nerve from a back disorder.
It is important in such
cases to determine which problem is causing most of the
pain: the hip or the back. If your problem is mainly in
your back, you may still be left with most of your pain after
going through a hip replacement, and you will not be very
happy with the result! If most of your pain is from the hip,
a hip replacement may have the added benefit of improving
your back condition as well, since the stiffness of an arthritic
hip can aggravate a back problem.
