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 degrees. This method offers excellent control of the osteotomy.
Coxa valga – Wikipedia
Coxa Valga Correction of coxa valga is a varus osteotomy of the femur. There is a risk that the greater trochanter may lose both tension and lever arm, which can lead to a lurch or Trendelenburg gait. A good example of a femoral varus osteotomy is the Nishio osteotomy. This example demonstrates that hip vlga can be corrected with osteotomy of the femur and not a pelvic osteotomy.
Coxa valga is a deformity due to an increase in the angle between the head and neck of the femur and its shaft normally degrees. Intra-articular and extra-articular surgical procedures can be performed to correct intra-articular deformities.
A – Bilateral severe hip dysplasia with elliptical femoral head on right side B – Wagner-type valgus osteotomy performed as well as periacetabular osteotomy PAO of the pelvis. If the differences are the same, there is no trochanteric overgrowth; if they vsra different, then trochanteric overgrowth is present.

Coxa Vara / Coxa Valga
Pectus excavatum Pectus carinatum. In the case of acquired coxa vara from a fracture, the proximal femur and femoral neck need coxxa reduction and rigid fixation to avoid potential serious complications.
The osteotomy is stabilized with blade plate internal fixation. Congenital coxa vara results in a decrease in metaphyseal bone as a result of abnormal maturation and ossification of proximal femoral chondrocyte.
The femoral osteotomy should be medially translated towards the inside to avoid a secondary translation deformity. Another example is a non-spherical femoral head can be treated by a Ganz femoral head reduction osteotomy FHRO. Patients may also show femoral retroversion or decreased anteversion.

For more information, see Perthes Disease. Deformity of the femur will often cause a resultant deformity in the acetabulum, and a deformity of the acetabulum will cause a resultant deformity in the femur.
Instead, both deformities are caused by the same disease process. As a result of congenital coxa varathe inferior medial area of the femoral neck may valba fragmented. The effect is to lengthen the femoral neck.
Wrist drop Boutonniere deformity Swan neck deformity Mallet finger. The other two osteotomies do not vada the part of the femoral head that articulates with the acetabulum. This osteotomy creates a relative lengthening of the femoral neck by shifting the trochanter laterally to the outside and distally downward.
Furthermore, the shape of the upper femur is affected by any imbalance of muscle forces around it. Coxa valga and coxa vara are deformities of the hip. The differential diagnosis includes neuromuscular disorders i.

The femoral neck length is increased Morscher Osteotomy 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. Next, a greater trochanteric osteotomy is performed to at the same angle and shifted distally downward and laterally to the outside.
Furthermore, the location of the greater trochanter on an anteverted femur promotes hip cara. The center of rotation of angulation CORA is at the center of the femoral head.
Correction of the deformity often requires correction in all three planes. This content reflects information from various individuals and organizations and may offer alternative or opposing points of view. Coxa vara is as a varus deformity of the femoral neck.
Correction of coxa valga is a varus osteotomy of the femur. Valgus angles greater than degrees put the patient at risk of hip subluxation dislocation. The more extreme and the more chronic a hip deformity, the more likely there are to be associated soft tissue contractures. 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.
These must be addressed during surgery with soft tissue releases. Furthermore, because varus osteotomy shortens the femur this has an varz on the greater trochanter. This will result in good stabilization of the vaga.
