Why would a patients leg measurements be unequal?

Why would a patients leg measurements be unequal?

This difference typically arises when bones are still growing. It may be an inherited trait or caused by trauma (such as breaking your leg as a child). In adults, unequal leg length can occur if you break a leg or undergo hip, knee or ankle surgery and end up with a shorter bone on one side.

What causes leg length differences?

There are many different reasons to have a leg length discrepancy, but there are two main causes: 1) your child was born with a condition that caused one leg to grow slower than the other or 2) something happened during your child’s lifetime that affected the length of the bone (i.e. a fracture) or affected the growth …

What would be a typical range for leg length discrepancy?

Limb length discrepancy (LLD) is a very common occurrence in the pediatric and adult population. In fact, the majority of individuals have some degree of limb inequality either in structure or function. The average discrepancy is less than 1.1 cm and usually patients easily compensate for this.

How do you fix short leg syndrome?

Doctors often “treat” structural SLS by placing a heel lift in the shoe of the shorter leg. A physical therapist determines the amount of lift required to restore the positioning of the spine and pelvis. For cases requiring surgical shortening or lengthening of a limb, the surgery must be followed by physical therapy.

Which conditions can result in leg length discrepancy?

Causes that shorten the leg are more common than those that lengthen it and include congenital growth deficiencies such as genetic conditions affecting growth, infections that affect the growth plate, tumors, fractures that occur through the growth plate, and radiation treatment for cancer.

How is leg length discrepancy ( LLD ) diagnosed?

Tests to Diagnose Leg Length Discrepancy (LLD) Physical examination/ test and X-ray may be used by a physician to test the leg length discrepancy (LLD). The cause of leg length discrepancy (LLD) may determine when the diagnosis will be done.

How can you tell the difference in leg length?

Standing on a flat and firm surface, place the blocks under the shorter leg until feeling even and balanced. You can also use thin hardback books or tiles. Then step off the block and use a ruler to take a measurement. This amount is known as the functional leg length difference. This may be different from the actual leg length difference.

Which is the best way to diagnose leg length inequality?

Examination and outcome measures. The most accurate method to identify leg (limb) length inequality (discrepancy) is through radiography. It’s also the best way to differentiate an anatomical from a functional limb length inequality.

What should I do if my leg length is less than 1 inch?

For patients with minor limb length discrepancies (less than 1 inch) and no deformity, treatment is usually nonsurgical in nature. Because the risks of surgery may outweigh the benefits, surgical treatment to equalize small differences in leg length is not usually recommended. Nonsurgical treatments may include: Observation.

How big of a problem is leg length discrepancy?

The effects of limb length discrepancy vary from patient to patient, depending on the cause and size of the difference. Differences of 3 1/2 percent to 4 percent of the total length of the leg (about 4 cm or 1 2/3 inches in an average adult) may cause noticeable abnormalities when walking.

What happens when there is a difference in leg length?

Patients who have differences of 3-1/2 to 4 percent of total leg length (about 4 cm or 1-2/3 inches in an average adult) may limp or have other difficulties when walking. Because these differences require the patient to exert more effort to walk, he or she may tire easily.
