leg length

[Guest guest]

Hi ...

I have heard from several specialists that the only true way to measure leg

length differences is with full x-rays of both legs. Most people with

scoliosis have a tilted pelvis, which makes their legs appear uneven.

Leg length discrepancy does not cause scoliosis. At least not with

everyone. I have a niece who has a 1-1/2 " leg length discrepancy. Because

of her relationship to me, we were sure it was a spine problem, and she went

to a scoliosis specialist. He found that she has an absolutely normal

spine, but x-rays of both legs showed the significant difference. I think

that leg length discrepancies of 1/2 " or under are considered normal.

I've tried using a lift in one shoe, but it didn't seem to make any

difference. I've known other people who swear by their lift. I think it's

just one more way of demonstrating that we're all very different.

I love that: 'potentially modifiable risk factor".............'spose they'll ever figure out that it is a pelvis obliquity problem?

But a GREAT study to show that it is, in fact, a secondary component.

Abstract

Background: Leg-length inequality is common in the general population and may accelerate development of knee osteoarthritis.

Objective: To determine whether leg-length inequality is associated with prevalent, incident, and progressive knee osteoarthritis.

Design: Prospective observational cohort study.

Setting: Population samples from Birmingham, Alabama, and Iowa City, Iowa.

Patients: 3026 participants aged 50 to 79 years with or at high risk for knee osteoarthritis.

Measurements: The exposure was leg-length inequality, measured by full-limb radiography. The outcomes were prevalent, incident, and progressive knee osteoarthritis. Radiographic osteoarthritis was defined as Kellgren and Lawrence grade 2 or greater, and symptomatic osteoarthritis was defined as radiographic disease in a consistently painful knee.

Results: Compared with leg-length inequality less than 1 cm, leg-length inequality of 1 cm or more was associated with prevalent radiographic (53% vs. 36%; odds ratio [OR], 1.9 [95% CI, 1.5 to 2.4]) and symptomatic (30% vs. 17%; OR, 2.0 [CI, 1.6 to 2.6]) osteoarthritis in the shorter leg, incident symptomatic osteoarthritis in the shorter leg (15% vs. 9%; OR, 1.7 [CI, 1.2 to 2.4]) and the longer leg (13% vs. 9%; OR, 1.5 [CI, 1.0 to 2.1]), and increased odds of progressive osteoarthritis in the shorter leg (29% vs. 24%; OR, 1.3 [CI, 1.0 to 1.7]).

Limitations: Duration of follow-up may not be long enough to adequately identify cases of incidence and progression. Measurements of leg length, including radiography, are subject to measurement error, which could result in misclassification.

Conclusion: Radiographic leg-length inequality was associated with prevalent, incident symptomatic, and progressive knee osteoarthritis. Leg-length inequality is a potentially modifiable risk factor for knee osteoarthritis.

I am having THR in the morning. Has anyone had a leg length difference

after this surgery?> > Thanks,

First LTKR was done Oct 5 2010 I did notice the new and oh so much improved knee

did feel taller then then

the right which needed it done also.. I even mentiond it to a few family members

and one of then said to stand on one

foot and measure yourself and then stand on the other foot and do the

same...amazingly it measured 1 " taller.. the knew

knee was now again straight instead of being bowed out.. after having the RTKR

done Feb 25, 2011 I no longer have

that feeling ... I did mention it to my surgeon and he said the difference was

so slight that he didn't think I should have

noticed a height difference in walking.. so maybe some of us are just more

sensitive to things like that.. :-)
