Coxa valga

Coxa valga describes a deformity of the hip where there is increased angle between the femoral neck and femoral shaft. 

Coxa valga is often associated with shallow acetabular angles and femoral head subluxation. 

Plain radiographs

Coxa valga occurs where the angle formed between the neck of the femur and its shaft (also known as the caput-collum-diaphyseal (CCD) angle or the femoral angle of inclination) is increased beyond >140 degrees. Normal is between 125-135 degrees in adults, but can be 20-25 degrees greater at birth and 10 degrees greater in children. When the angle is <120 degrees, this is considered coxa vara.

Femoral anteversion and rotation can affect measurement accuracy and should be considered when measuring angles. 

Coxa valga can be associated with genu varum and lead to increased stress and early degenerative changes in the medial compartment of the knee.

Coxa valga can be treated with varus derotation osteotomy (VDRO) and angled blade-plate fixation 2
