As a result of congenital coxa cpxathe inferior medial area of the femoral neck may be fragmented. Coxa vara is usually indicated when the angle is less than degrees. Macrocephaly Platybasia Craniodiaphyseal dysplasia Dolichocephaly Greig cephalopolysyndactyly syndrome Plagiocephaly Saddle nose.

Retrieved from ” https: AP radiographs in standing are taken, usually of both hips in a neutral position. These deformities occur when the angle formed by the head of the femur and the shaft of the femur is abnormal. The other two osteotomies do not change the part of the femoral head that articulates with the acetabulum.

This is achieved by performing a valgus osteotomy, with the valgus position of the femoral neck improving the action of the gluteus muscles, normalising the femoral neck angle, increasing total limb length and improving the joint congruence. The blade plate is then secured into place. Coxa vara is as a varus deformity of the femoral neck. Anteversion of the femur inward twisting can create coxa valga. In this case study, the acetabulum is abnormal in coxa vara.

Deformities of the hip can be divided into coxa valga and coxa vara.

Is knee replacement the only option if I have bone on bone in my Correction of the deformity often requires correction in all three planes.

The Ganz osteotomy does not actually lengthen the femur, as the Morscher and Wagner approaches do. That is usually the journal article where the information was first stated. Each of these approaches has the same underlying goal: It’s an intricate system affected by your metabolism, nutrition, medications, wear-and-tear and medi From Wikipedia, the free encyclopedia.


Acetabular dysplasia and femoral anteversion are usually associated with one another. MRI can be used to visualise the epiphyseal plate, which may be widened in coxa vara. For more information, see Slipped Capital Femoral Epiphysis. Hip, Groin, or Buttock Problem. Retrieved from ” https: One example is the deformity of the femoral head relative to the neck created by a slipped capital femoral epiphysis can be treated by an intra-articular reduction or osteotomy or an extra-articular reorientation osteotomy.

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. Vrije Universiteit Brussel Project. What causes the knuckle popping sound? Contents Editors Categories Share Cite.

Premature epiphyseal closure is described as one of the ethiological factors of coxa vara. The combination of the two techniques results in increased length of the femoral neck. There is less danger to the vata of the femoral head than with the other two approaches because the dislocation helps avoid injury to the femoral head.

Our approach is to perform the osteotomy distal down to the lesser trochanter to minimize tension on the psoas tendon. Computerized tomography CT may be useful to evaluate the shape of the femoral head and acetabulum. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. If the differences are the same, there is no trochanteric overgrowth; if they are different, then trochanteric overgrowth is present.

The indication is when there is no need to change the congruity of the joint.

Due to the low incidence of coxa vara and even lower for coxa valga, there is little literature currently available. The Morscher osteotomy does not change the orientation of the femoral head in the acetabulum and therefore the congruity of the hip joint stays the same.


An associated dysplastic acetabulum can lead to a hip subluxation. At the Paley Institute, we offer the most technologically advanced treatment methods, with an emphasis on joint reconstruction and preservation over joint replacement.

Magnetic resonance imaging MRI can be used to illustrate the soft tissues and assess impingement. The osteotomy allows the proximal femur to be turned inwards because it does not elevate the greater trochanter. CT can be used to determine the degree of femoral anteversion or retroversion. Next, a greater trochanteric osteotomy is performed to at the same angle and shifted distally downward and laterally to the outside.

In the case of acquired coxa vara from a fracture, the proximal femur and femoral neck need accurate reduction and rigid fixation to avoid potential serious complications.

A combined intra-articular and extra-articular impingement of the hip is best addressed with this approach. Coxa Valga Correction of coxa valga is a varus osteotomy of the femur. The normal NSA of the femur is degrees. Articles lacking sources from December All articles lacking sources Infobox medical condition new All stub articles. Therefore, when coxa vara is seen with hip dysplasia, it is not the cause of the dysplasia.
