COXA VALGA E VARA PDF

Coxa valga describes a deformity of the hip where there is an increased angle between the femoral When the angle is vara. Deformities of the hip can be divided into coxa valga and coxa vara. Coxa valga is a deformity due to an increase in the angle between the head and neck of the. Coxa valga is increased in femoral neck-shaft angle tp more than degrees. Like coxa vara, coxa valga could be congenital or acquired.

What are coxa valga and coxa vara?

One example of coxa vara with hip dysplasia is in Congenital Femoral Deficiency Femoral deformities can also arise after treatment of w dysplasia.

The most serious ones with high and long term morbidity being osteonecrosis and coxa vara. Ten years after Nishio varus osteotomy The femoral osteotomy should be medially translated towards the inside to avoid a secondary translation deformity. Furthermore, because varus osteotomy shortens the femur this has an effect on the greater trochanter.

Developmental Coxa Vara – Pediatrics – Orthobullets

The normal NSA of the femur is degrees. The shaft of the femur is not vars laterally, however, a major difference with the Morscher osteotomy.

Coxa vara, on the other hand, produces more amenable forces on the acetabulum. For more information, see Slipped Capital Femoral Epiphysis. Another possible explanation for the high occurrence of coxa vara is the loss of reduction after initial fracture reduction of implant failure in unstable fractures. Arthrogryposis Larsen syndrome Rapadilino syndrome.

The osteotomy is performed and the bone corrected to the desired position. The greater trochanter is lateralized, increasing abductor lever arm. Coxa valga is a deformity due to an increase in the angle varw the head and neck of the femur and its shaft normally degrees. The Morscher osteotomy does not change the orientation of the femoral vsra in the acetabulum and therefore the congruity of the hip joint stays the same. Instead, both deformities are caused by the same disease process.

The differential diagnosis includes neuromuscular disorders i. Deformity of the femur will often cause a resultant deformity in the acetabulum, and d deformity of the acetabulum will cause a resultant deformity in coda femur.

AP radiographs in standing are taken, usually of both hips in a neutral position.

The long axis of the elliptical vslga head is now horizontal. The acetabulum is the socket-shaped surface of the pelvis where the femoral head sits. The Wagner osteotomy is used to change the part of the femoral head that is articulating with the acetabulum.

What are coxa valga and coxa vara?

In some cases, an osteotomy of the iliac wing of the pelvis is performed to shorten the requisite amount for muscle reattachment. Example of normal proximal femoral angles.

By the adolescent Growth Growth includes the processes [Modeling is also part of bone growth] that causes increase length and girth before the vagla of to epiphyseal plate closure [There is gain in length after epiphyseal plate closure].

The Ganz osteotomy is combined with a capsulotomy coxq a safe-surgical dislocation of the hip. Deformity of the hip joint may be due to femoral deformity and acetabular dysplasia.

There are 3 types Coxa Vara, acquired, congenital and developmental, usually displaying greater acetabular dysplasia and an abnormal acetabulum. The hip is well covered, protecting it during lengthening Ganz Osteotomy The Ganz osteotomy is combined with a capsulotomy and a safe-surgical dislocation of the hip.

Physiopedia articles are best used to find the original sources of information see the references list at the bottom of the article. The internal nail is then applied and locked into place. Furthermore, the location of the greater trochanter on an anteverted femur promotes hip dysplasia. Therefore, when coxa vara is seen with hip dysplasia, it is not the cause of the dysplasia.

Developmental Coxa Vara

A good example of a femoral varus osteotomy is the Nishio osteotomy. It can be associated with genu varum and lead to increased stress and early degenerative changes in the Medial Towards the median plane.

Protrusio acetabuli Coxa valga Coxa vara. One example is a deformity of the shape of the femoral head. The center of rotation of angulation CORA is at the center of the femoral head.
