Clinical feature: presents after the child has started walking but before six years of age. Usually associated with a painless hip due to mild abductor weakness and mild limb length discrepancy. If there is a bilateral involvement the child might have a waddling gait or trendelenburg gait with an increased lumbar lordosis.
Femur length: The superior aspect of the femoral head and the distal portion of the medial femoral condyle. Tibial length: The medial tibial plateau and the tibial plafond; As previously mentioned, leg length difference can result from a repetitive activity that misaligns, one example being pelvic torsion; this is a functional LLD.
Common complications that can arise include leg-length discrepancy, joint contracture, growth retardation, low bone mineral density, and macrophage activation syndrome. [6] Some causes or potential risk factors denoting a higher chance of developing childhood arthritis have been identified. [7]
Paradoxically, limbs where a large joint (such as the knee) is inflamed may have increased growth in the short term, leading to limb-length discrepancy (i.e. one arm or leg is slightly longer than the other). This is due to increased blood supply to the bony growth plates surrounding the inflamed joints.
These conditions exist in persons with leg-length inequality, scoliosis, a history of polio, poor-quality footwear, and hip osteoarthritis. [1] There is also a notable incidence of lumbar spinal fusion patients that present with sacroiliac pain and hypermobility, potentially due to the adjacent lumbar joints being fixed and unable to move.
Although prone "functional leg length" is a widely used chiropractic tool, it is not a recognized anthropometric technique, since legs are often of unequal length, and measurements in the prone position are not entirely valid estimates of standing X-ray differences. [21] Measurements in the standing position are far more reliable. [22]
Distraction osteogenesis (DO) is used in orthopedic surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. [1] [2] [3] It was originally used to treat problems like unequal leg length, but since the 1980s is most commonly used to treat issues like hemifacial microsomia, micrognathism (chin so small it causes health problems), craniofrontonasal ...
Leg length discrepancy after hip replacement is calculated as the vertical distance between the middle of the minor trochanters, using the acetabular tear drops [94] or the transischial line [16] as references for the horizontal plane. A discrepancy of up to 1 cm is generally tolerated. [94] [16]
