Members don't see this ad.

can anyone comment on what the compensation during gait would be for the long limb vs the short limb in limb length discrepancy in reguar to pronation or suppination of the STJ, calcaneal inversion or eversion etc. I would like to know whether the short limb would pronate or long limb would pronate.

I understand the various signs seen at the hip, head and shoulders etc and the difference between compensation vs uncompensated.

Thanks, mildoc 2016

The long limb (or equinus limb if one side has more equinus... ACL tear, etc) tends to pronate. Short side will also supinate a tad, but it's not as pronounced. Pronation shortens the limb, and it is the body's correctional adjustment for limb length.

You will see (and remember) this concept in kids who have painful pes planus (flatfoot) reconstruction surgery are suddenly 1-2in taller on the post-op side until you go back and correct the contralateral ~6mo later and balance them out.

since the long limb is pronated, the plantar fascia is tensed resulting in pain and effecting the windlass stuff. when you will reach the "FIRST Ray" topic in biomechanics you will see it.
