Best answer: How common is leg length discrepancy after hip replacement?

Discrepancy of leg length is common after arthroplasty of the hip. In the literature, the mean LLD varies from 1 to 15.9 mm. LLD has been perceived in between 6%20 and 32%19 of patients and universally perceived when shortening exceeds 10 mm and lengthening 6 mm.

Can I sue if one leg longer after hip replacement?

Unequal Leg Length Can Be Avoided in Hip Replacement Surgery

Significant lengthening of the operated leg of greater than 3/4 inch (1.5 cm) or longer, is considered by many orthopedic hip experts to be an unacceptable complication caused by the surgeon’s negligence and may be grounds for a medical malpractice claim.

Can leg length discrepancy be corrected?

If a child has stopped growing, orthopedists can sometimes correct a leg length discrepancy by shortening the longer leg. This is done by removing a piece of bone from the longer leg. Limb lengthening surgery also can be done.

How do orthopedic surgeons measure for leg length when replacing a hip joint?

In the device group, the leg-length was assessed using the PCA limb lengthening gauge, which is composed of 2 pins (diameter, 3.2 mm) and a gauge. The pins were inserted into the acetabulum and the greater trochanter, and the surgeon measured the distance between the pins (Fig. 1).

A leg length discrepancy may be functional or structural in nature. Minor discrepancies often cause no symptoms or problems. However, moderate-to-severe asymmetry may cause issues with walking and posture, and it can contribute to hip and back pain.

Why does my lower leg hurt after hip replacement?

You can expect to experience some discomfort in the hip region itself, as well as groin pain and thigh pain. This is normal as your body adjusts to changes made to joints in that area.

How do you calculate leg length discrepancy?

An apparent leg length can be measured from the umbilicus to the medial malleoli of the ankle (Fig. 2). A “direct” measurement using a tape measure can be utilized to measure the “true” leg length from the anterior superior iliac spine (ASIS) to the medial malleolus.

How does leg length discrepancy affect gait?

There have been several studies showing that mild LLD causes kinematic compensation of the lower limbs leading to gait deviations. Two studies demonstrated that mild LLD induces biomechanical changes in the lower limbs and leads to asymmetrical gait deviations.

Those who suffer from functional leg length discrepancy are those who tend to suffer from lower back pain. The Academy of Clinical Massage shares that tight back muscles on the “short side” are often the cause of the leg length difference.

Does one hip replacement lead to another?

Results — During the study period patients were twice as likely to have their contralateral hip replaced than to die. However, with passing time, probabilities converged and for a patient who only had 1 non-revised THA at 10 years, there was an equal chance of receiving a second THA and dying (24%).

Is leg length discrepancy a disability?

The disability from LLI is generally associated with the long leg, but may be associated with the short leg depending on individual circumstances. The disability from LLI may be associated with resultant compensation mechanisms for LLI , such as pelvic tilt and scoliosis.
