Subject: Re: Leg Length Discrepancy - Please help!
Dear Dr. Blake,
I am not sure if you do provide your advice through email correspondence
but I am taking a last plunge to try to contact someone who may at last
have the requisite knowledge and experience to help me with my problem as I
have just about exhausted every other avenue! I have just read your 2007
Podiatry Today article on LLD and for the first time have read an article
that so accurately describes many of my own conditions.
I have lived and worked in Hong Kong since 1992 although I am originally
from Liverpool, England. I am now 40 years old and I have been a passionate
runner for the last 15 years. I stepped up to marathons about 6 years ago
and am now training for an ironman and have entered the 2016 marathon des
sables race across the Sahara.
As a child I broke my left femur aged two and my right femur aged three.
When I first started to get running injuries, a chiropractor diagnosed that
I had LLD and taught me several stretches to alleviate tightness that was
resulting. He informed me that I had naturally tilted my pelvis forward to
compensate, had slight scoliosis in the back but that this wouldn't worsen
and that as long as I stretched I would keep the injuries at bay.
At this time I wasn't running too many miles per week and so the stretching
worked. Then, I stepped up to marathons and the real problems began. I
sought advice from physios and chiros again and was constantly told I
needed custom made orthotics which I duly bought but hardly wore as they
were far too restricting for my running.
I would go though periods of being injury free as long as I continued to
stretch and strengthen BUT I really struggled to put two consecutive
quality training days back to back, always having to hobble the day after a
On hitting 40 I decided to go for a PB in the London marathon - training
135Km per week and succeeded in running 2hrs 32 mins. To achieve this I had
my lower limbs x-rayed to find out the exact LLD which was 2cm in my right
leg. I therefore experimented with different insoles and ended up putting
an 8mm insole in the right shoe. This just about got me through the
training but I was never really pain free and it nearly put me off running
I do severely overpronate in my left foot - no doubt to also compensate
for the shorter right limb and so I would like your opinion on whether or
not the insole solution is all that should be required or if I should
combine it with orthotics somehow?
What I don't understand is that when I have been measured for orthotics,
my LLD has never been taken into consideration and surely I only
overpronate to compensate for LLD? So what good are orthotics for me?
Surely if I correct the LLD I wouldn't overpronate as the left foot
wouldn't need to? In addition, as the first Chiro told me, over the last
thirty plus years my body has adjusted itself to deal with the LLD and so
exactly how much insole should I be using? surely not the whole 2cm as
there has probably been too much ligament/tendon change to be able to
simply measure the LLD and substitute it with an insole (although 2cm is
too much to put in one shoe anyway)
I would love to be able to run pain free and be able to near the end of
long runs without feeling the tightness in the hamstrings and glutes which
I inevitably get nowadays and that really slows me down. I am still a
competitive runner but lose so much training time because I cant run pain
free on consecutive days. I am just looking for qualified advice instead of
from non-sportsmen who have little understanding of the punishing training
regimes i undertake to achieve my goals.
Any help/advice would be greatly appreciated!
First of all, one assumption is always made in this scenario that the leg length discrepancy is responsible for most of the symptoms. Correction of the severe over pronation of the long left leg may be the answer to the remaining soreness. The orthotics designed must have much more correction on the left side to fully correct the pronation, compensatory or not. One approach is to stay with the 8 mm lifts on the right for now and work with someone who can fully correct the left and right foot pronation. Pronation causes anterior tilt of the pelvis leading to its own set of hip, pelvic, and low back pains. Golden Rule of Foot: Do not under treat the asymptomatic side. There are so many types of orthotic designs out there that you should be able to have one made that is not too rigid.
from the back on a treadmill running at 7 min/mile pace, no incline, first focused on the heels of your shoes, and then your whole body, and email me with it to look at.
www.yoursole.com) as one possible orthotic correction device. Get the soft athletic version, and heat them to custom fit. The lifts on the right side go underneath, and should be full length, at least to the metatarsals. The left arch can be built up by adding material. If someone in your area understands varus wedging for pronation control, then the left side can be varus wedged more than the right. Running shoes can also be varus wedged up to 3/8 inch in the mid sole fairly easily, and along with power lacing, can take some or most of the responsibility away from the orthotic devices to control the pronation. This usually makes the orthotics more comfortable.
Fifthly, as a maturing athlete (hope you take no offense!!), quality workouts four days a week in the main sport (running), mixed with cross training 2 other days , and a full rest day off per week, makes the body stronger, more resistant to injuries, and perform at a higher level. When an athlete comes from a 80+ mile/week background, it is hard to find happiness when not working out at full speed daily. This area may need some work. There are many great coaches, like my buddy Marc Evans, world renowned triathlon coach. See his website at www.evanscoaching.com.
Sixthly, you really need a good hamstring, quadriceps, hip muscles, low back/core strength review. Sounds like you know what muscles to stretch, and this predictably helps you. If you have a scoliosis, this evaluation can go higher. Even asymmetrical shoulder strength can put an abnormal torque on your pelvis (remember right hip functions with the left shoulder). I have found so many athletes, even world class runners, with poor hamstring strength for example. And I think it is even worse when it is asymmetrical.
So, I hope this helps you in some way. I am happy to help you further by having recontact me. Good Luck!!
