Two forms of femoral dysplasia are coxa vara, in which the femur head grows at too narrow an angle to the shaft, and coxa valga, in which the angle is too wide. A rare type, the "Beukes familial hip dysplasia" is found among Afrikaners that are members of the Beukes family. The femur head is flat and irregular.
Coxa valga is a deformity of the hip where the angle formed between the head and neck of the femur and its shaft is increased, usually above 135 degrees.. The deformity may develop in children with neuromuscular disorders (i.e. cerebral palsy, spinal dysraphism, poliomyelitis), skeletal dysplasias, and juvenile idiopathic arthritis.
Coxa valga >125 degrees. Coxa vara <125 degrees. Knee: genu valgum (from Latin genu = knee) – the tibia is turned outward in relation to the femur, resulting in a "knock-kneed" appearance. Common causes of knock-knee in adults include arthritis of the knee and traumatic injuries.
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 is correct for a knock-kneed deformity to be called both a varus deformity at the hip (coxa vara) and a valgus deformity at the knee (genu valgum); although the common terminology is to simply refer to it as a valgus knee. When the terminology refers to a bone rather than a joint, the distal segment of the bone is being described.
Nevertheless, coxa profunda had been found in 76% of asymptomatic hips, mainly in women. Therefore, this as an isolate criterion is not enough to make the diagnosis of pincer-type impingement. A more severe condition is protrusio acetabuli, diagnosed when the femoral head overlaps or overpasses the ilioischial line.
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. Its opposite is coxa valga . Designations of abnormal femur angles.
Coxalgia (/kok sáljə/), also known as coxodynia (/koks'ō-din'ē-ă/, from Latin coxa 'hip' and algia/odyne 'pain'), is defined as pain in the hip or disease-related pain of the hip. Coxalgia refers to general sensation of pain in the hip area, including the muscles surrounding the hip – sartorius , tensor fasciae latae , ilio-tibial ...
