Surgeries help treat hip dysplasia and impingement in younger individuals
                              

For young patients suffering from hip dysplasia or impingement, replacement and resurfacing used to be the only treatment
options. That’s no longer the case.
                              

Today,
Javad Parvizi, MD, joint specialist at the Rothman Institute at Thomas
Jefferson University Hospital, performs two innovative procedures that
treat pain and loss of mobility by preserving a patient’s native hip
joint – rather than replacing or resurfacing it.

And he is the only orthopaedic surgeon in the Philadelphia region and one of only about a dozen in the United States to do so.
                              
                              

“Prior
to preservation techniques, patients as young as 14 had no options but
to try medications like non-steroidal anti-inflammatory drugs (NSAIDs),
or to have a replacement or resurfacing procedure,” says Dr. Parvizi,
who is also associate professor of Orthopedic Surgery at Jefferson
Medical College, Thomas Jefferson University. 

“A
replacement is basically cutting the joint and throwing it away, so if
five or 10 years from now we develop a way to restore or substitute
cartilage, or discover other forms of treatment, replacement patients
will not be candidates,” adds Dr. Parvizi. “Preservation is a win-win
for younger, qualified patients, not only because it reduces pain and
restores mobility, but also because it allows for a wide range of
future options if arthritis progresses down the road.” 
                              

These
options include both hip resurfacing and total hip replacement because
the patient comes out of surgery with their own anatomy intact. Unlike
hip replacement or hip resurfacing, hip preservation does not require
implants or devices to be positioned in place of the natural joint. 

Dr. Parvizi performs two types of hip-preserving procedures – periacetabular osteotomy and femoroacetabular osteoplasty.

Relief for hip dysplasia
Hip
dysplasia is a condition where the head of the femur (the thigh bone)
only loosely or partially fits into the acetabulum (concave socket in
the pelvis) and the femoral head or acetabulum is misshapen, causing
abnormal wear and tear within the joint as it moves.

Periacetabular
osteotomy can help some patients with hip dysplasia, which is caused by
a combination of genetic and environmental factors and is one of the
leading causes of degenerative arthritis.   

As
the more complicated of the two procedures, the periacetabular
osteotomy usually involves making several cuts in the pelvis to realign
the angle of the acetabulum so that the femoral head can fit properly
into place. It may also involve smoothing of a misshapen femoral head
to eliminate the friction caused by its movement. Dr. Parvizi says that
recovery takes up to three months.

Treating hip impingement
Hip
impingement – or, more precisely, femoral acetabular impingement – is a
disorder that’s increasingly recognized as a cause of hip pain in
active adults and a previously unrecognized cause of arthritis in young
adults. Impingement is caused by a lack of room between the neck of the
femur and the rim of the acetabulum, causing the neck and rim to jam
together as the hip is flexed (as in sitting or running). 

As Dr. Parvizi explains, this jamming leads to pain manifested in the hip or groin region and may lead to early degenerative arthritis of the hip.
                              
                              

To
help patients with this condition, Dr. Parvizi developed the second
surgery – a femoroacetabular osteoplasty. This procedure focuses on
smoothing the surface in the space between the neck and the head of the
femur, and requires a recovery of about six weeks.

Are you a candidate?
To be eligible for either of these procedures, patients should be under 50 years of age. And if arthritis is already present,
it must not have progressed past stage three.
                              

Though the preservation procedures can be more technically difficult, there are clear benefits to keeping your own joint,
says Dr. Parvizi.
                              

“Patients can go back to regular activities without limitations, and there is less risk of post-operative infection than with replacement surgery,” he notes. “Also, there is little to no risk of the joint dislocating.”
