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]
Unequal leg length with a very small degree of difference can be common; small inequalities in leg length may affect 40%-50% of the human population. It has been estimated that at least 0.1% of the population have a difference greater than 20 mm (0.79 in).
Coxa vara is a deformity of the hip, whereby the angle between the head and the shaft of the femur is reduced to less than 120 degrees. This results in the leg being shortened and the development of a limp. It may be congenital and is commonly caused by injury, such as a fracture.
limb length discrepancy (evaluated by placing the child in a supine position with the hips and knees flexed [unequal knee heights might be noticed – the Galeazzi sign]), and; restricted hip abduction. Sometimes during an exam a "click" or more precisely "clunk" in the hip may be detected [24] (although not all clicks indicate hip dysplasia). [25]

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 ...
Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. Joint replacement surgery is often indicated from various joint diseases, including osteoarthritis and rheumatoid arthritis. [citation needed] Joint replacement has become more common, mostly with knee and hip ...
An example is compensating for a leg length discrepancy, equivalent to replacing a missing part of a limb. Another example is the replacement of the forefoot after a forefoot amputation. This treatment is often made from a combination of a prosthesis to replace the forefoot and an orthosis to replace the lost muscular function (ortho prosthesis).
