Rheumatology. Unequal leg length (also termed leg length inequality, LLI or leg length discrepancy, LLD) is often a disabling condition where the legs are either different lengths (structurally), or appear to be different lengths, because of misalignment (functionally). Unequal leg length with a small degree of difference is very common; small ...
Hemipelvectomy, also known as a pelvic resection, is a surgical procedure that involves the removal of part of the pelvic girdle. This procedure is most commonly performed to treat oncologic conditions of the pelvis. [ 1 ][ 2 ] Hemipelvectomy can be further classified as internal and external hemipelvectomy. [ 1 ][ 2 ] An internal ...
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. It can also occur when the bone tissue in the neck of the femur ...
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).
Leg length discrepancy after hip replacement is calculated as the vertical distance between the middle of the minor trochanters, using the acetabular tear drops [90] or the transischial line [16] as references for the horizontal plane. A discrepancy of up to 1 cm is generally tolerated. [90] [16]
Hintermann states, "Compensatory overpronation may occur for anatomical reasons, such as a tibia vara of 10 degrees or more, forefoot varus, leg length discrepancy, ligamentous laxity, or because of muscular weakness or tightness in the gastrocnemius and soleus muscles." [10] Pronation can be influenced by sources outside of the body as well ...
Heel lift. Heel lifts, also known as shoe inserts, are commonly used as therapy for leg-length differences leading to knee, hip, and back pain. They attempt to reduce stress on the Achilles' tendon during healing, and for various rehabilitation uses. The intent of a heel lift is not to absorb shock or spread pressure on the foot, but to raise ...
[12] [13] The Activator Methods technique uses leg length checks while prone (Position 1) and with the knees bent to 90 degrees (Position 2). Research shows good intraexaminer reliability and moderate interexaminer reliability with leg length checks in position 1, however no consensus has been met on the accuracy of leg length checks in position 1.
