2024年8月7日 · Coxa valga occurs when 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 >140º. Normal is between 125-135º in adults, but can be 20-25º greater at birth and 10º greater in children.

2021年12月10日 · coxa valga: >140° coxa vara: <120° Potential measurement errors. Potential measurement errors radiographically caused by external rotation of the femur can cause a change of >10° in the apparent femoral neck-shaft angle with …

Bilateral coxa valga is usually seen in children with cerebral palsy or other neuomuscular conditions. It is unusual to see in the absence of those conditions or previous trauma.

Both proximal femurs demonstrate coxa valga. Pelvis and femoral heads are normal.

2024年8月7日 · Coxa vara describes a hip deformity where the femoral neck-shaft angle is decreased, usually defined as <120°. Pathology. It can be congenital or acquired. The common mechanism in congenital cases is a failure of the medial growth of the physeal plate 3. Etiology

2021年2月21日 · coxa valga and coxa vara: relation of the femoral shaft to the femoral neck; coxa vara: femoral neck is in a relatively flat position; coxa valga: femoral neck is relatively steep; genu varum and genu valgum: depends on the direction of distal part of the tibia (which is the distal component of the knee joint) genu valgum: distal part pointing ...

2023年12月15日 · Terminology. Actually describing the intrinsic rotation of the femur over its length from the hip to the knee, femoral anteversion may also be more aptly termed femoral antetorsion.. Some authors will distinguish femoral neck version as the angle of the femoral neck relative to the pelvic horizontal (interischial line), with a normal range of 5–25° of anteversion 3 …

2024年1月12日 · Chronic hip subluxation most common occurs in pediatric patients with neuromuscular disorders (e.g. cerebral palsy). It is considered a form of developmental hip dysplasia. Epidemiology Chronic hip subluxation occurs in ~45% of cerebral palsy ...

2022年9月16日 · Coxa plana is flattening of the femoral head epiphysis and is associated with many skeletal disorders: Legg-Calvé-Perthes disease; hemophilic hemarthrosis; Gaucher disease; hypothyroidism ; spondyloepiphyseal dysplasia; multiple epiphyseal dysplasia ; hemoglobinopathies, e.g. sickle cell anemia, thalassemia; See also. coxa magna; coxa vara ...

2022年9月27日 · Coxa profunda refers to a deep acetabular socket (i.e. increased acetabular depth). Epidemiology. Coxa profunda is much more common in females. Radiographic features Plain radiograph. On AP pelvis x-rays it is seen as the lateral border of the acetabular teardrop being in line with or medial to the ilioischial line 4. Differential diagnosis
