Examining Leg Length Difference

Asymmetry is a clue that a LLD is present. The center of gravity will shift to the short limb side and patients will make an effort to compensate, displaying indications such as pelvic tilt, lumbar scoliosis, knee flexion, or unilateral foot pronation. Asking simple concerns including, "Do you favor a single leg over the other?" or, "Do you discover it uncomfortable to stand?" may well also provide some beneficial information and facts. Performing a gait evaluation will yield some clues as to how the patient compensates for the duration of ambulation. Working with plantar pressure plates can indicate load pressure differences between the feet. It really is beneficial if the gait analysis is usually video-recorded and played back in slow motion to catch the subtle aspects of movement.

Calibrating Leg Length Imbalances

Among the golden guidelines in pedorthics is that you always measure a patient's two feet ahead of fitting a pair of shoes. You never ever trust within the sizing that they tell you. Likewise, it can be essential which you measure the LLD, whether structural or functional, oneself. Measuring for a LLD is just not an precise science; there's no clinical consensus as to which anatomical references need to be made use of or how the patient must be positioned. In addition, direct measurement outcomes using a tape might be hard to reproduce across practitioners, and they're going to only indicate a structural LLD. It could be best to utilize quite a few techniques to develop a composite picture. For a direct measurement, the strategy that is certainly recommended is always to measure from the anterior superior iliac spine to the medial malleolus. This measurement will give you the actual limb length difference. Other procedures include things like palpation, frontal plane observation, X-rays, and use of a measurement screen. Even so, this really is only a starting point for treatment. There exists no agreement as towards the amount of a measured distinction that ought to trigger an intervention! Anecdotally, it appears that for LLDs greater than �" some form of remedy be recommended for the patient, while a lot of situations greater than this might be asymptomatic. The preferred course is always to proceed with an indirect measurement. I'm not so much concerned with what the LLD is as I am concerned with what the patient can tolerate and what makes him or her comfortable. I favor to measure the correction.


Leg length discrepancy could be measured by a physician through a physical examination and by way of X-rays. Ordinarily, the physician measures the level of the hips when the child is standing barefoot. A series of measured wooden blocks may well be placed below the brief leg until the hips are level. If the physician believes a extra precise measurement is required, he or she could use X-rays. In expanding children, a physician may repeat the physical examination and X-rays each six months to a year to see if the leg length discrepancy has elevated or remained unchanged.

Non Operative Treatment

For modest leg length discrepancy in subjects with no deformity, remedy might not be required. Because the risks could outweigh the advantages, surgical therapy to equalize leg lengths is normally not proposed if the distinction is much less than 1 inch. For these modest differences, the doctor may perhaps advise a shoe lift. A lift fitted for the shoe can typically strengthen walking and operating, as well as eliminate any back discomfort that may perhaps be induced by the limb length discrepancy. Shoe lifts inserts are inexpensive and may be removed if they're not powerful.
