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 inequalities ...
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]
Stabilize the pelvis and let the affected leg drop. A positive test is indicated if the leg does not adduct to the table. [1] Thomas test for tight hip flexors both performed by the provider holding the unaffected leg to the chest and leaving the affected leg on the table. If the affected leg cannot lie flat on the table it is a positive test. [1]
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 ...
1 in 1,000 (term babies) [ 3 ] Hip dysplasia is an abnormality of the hip joint where the socket portion does not fully cover the ball portion, resulting in an increased risk for joint dislocation. [ 1 ] Hip dysplasia may occur at birth or develop in early life. [ 1 ] Regardless, it does not typically produce symptoms in babies less than a year ...
Hip resurfacing has been developed as a surgical alternative to total hip replacement (THR). The procedure consists of placing a cap (usually made of cobalt-chrome metal), which is hollow and shaped like a mushroom, over the head of the femur while a matching metal cup (similar to what is used with a THR) is placed in the acetabulum (pelvis socket), replacing the articulating surfaces of the ...
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 ...
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 ...
