A – Bilateral severe hip dysplasia with elliptical femoral head on right side B – Wagner-type valgus coca performed as well as periacetabular osteotomy PAO of the pelvis. 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. One example of coxa vara with hip dysplasia is in Congenital Femoral Deficiency.
What are coxa valga and coxa vara?
Correction of coxa valga is a varus osteotomy of the femur. Each of these approaches has the same underlying goal: Furthermore, because varus osteotomy shortens the femur this has an effect on the greater trochanter.
A good example of a femoral varus osteotomy is the Nishio osteotomy. If the angle is greater thanthis is referred to as coxa valga.
Coxa Vara / Coxa Valga – Physiopedia
Acetabular index AI and sourcil slope SS are significantly different than in the normal acetabulum. Wrist drop Boutonniere deformity Swan neck deformity Mallet finger. For example, treatment for avascular necrosis can result in growth arrest of the upper femur. When performing osteotomies of the hip joint, it is crucial to consider the surrounding soft tissues.
Therefore, when coxa vara is seen with hip dysplasia, it is not the cause of the dysplasia. The indication is when there is no need to change the congruity of the joint.
This article about a disease of musculoskeletal and connective tissue is a stub. Our approach is to perform the osteotomy distal down to the lesser trochanter to minimize tension on the psoas tendon. The main indication is improved congruity and reduction of joint forces when the femoral head is not spherical. The external fixator pins are placed outside the path of the planned nail.
There are 3 types Coxa Vara, ckxa, congenital and developmental, usually displaying greater acetabular dysplasia and an abnormal acetabulum. Views Read Edit View history. Magnetic resonance imaging MRI can be used to illustrate the soft tissues and assess impingement. The Nishio osteotomy at the base of the neck. X-rays provide most of the information needed for diagnosis. Correction of coxa vara is a valgus osteotomy.
For more information, see Hip Dysplasia Deformities of the hip can be divided into coxa valga and coxa vara. The normal NSA of the femur is degrees.
Wagner Osteotomy The Wagner osteotomy is used to change the part of the femoral head that is articulating with the acetabulum. The content on or accessible through Physiopedia is for informational purposes only. Cleidocranial dysostosis Sprengel’s deformity Wallis—Zieff—Goldblatt syndrome.
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. Surgery is the most effective treatment protocol. Unsourced material may be challenged and removed.
Toggle navigation p Physiopedia. The objective of medical interventions is to restore the neck-shaft angle and realigning the epiphysial plate to decrease shear forces and promote ossification of the femoral neck defect.
This human musculoskeletal system article is a stub. Coxa vara, on the other hand, produces more amenable forces on the acetabulum. The Wagner osteotomy is used to change the part of the femoral head that is articulating with the acetabulum. Anteversion of the femur inward vakga can create coxa valga. Winged scapula Adhesive capsulitis Rotator cuff tear Subacromial bursitis.
Signs to look out for are as follows:. Vrije Universiteit Brussel Project. This will result in good stabilization of the hip. The center of rotation of angulation CORA is at the center of the femoral head. Avlga Ectromelia Phocomelia Amelia Hemimelia. Due to the low incidence of coxa vara and even lower for coxa valga, there is little literature currently available. The other two osteotomies do not change the part of the femoral head that articulates with the acetabulum.
Please help improve this article by adding citations to reliable sources.
The greater trochanter is then moved distally downward increasing tension on the hip abductors and increasing abductor lever arm. The blade plate is then secured into place.
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. The osteotomy is stabilized with blade plate internal fixation.
Developmental Coxa Vara – Pediatrics – Orthobullets
We developed a method called fixator-assisted nailing in which the deformity is first stabilized with an external fixator, and then with internal fixation. A previous pelvic avlga had been performed B – Ganz relative neck lengthening and trochanteric transfer Intra-Articular Deformities Intra-articular deformities of the hip are deformities of the femoral head at its connection to the femoral neck. Instead, both deformities are caused by the same disease process.
There are three approaches to correction of trochanteric overgrowth, each with separate indications:. A progressive varus deformity might also occur in congenital coxa vara as well as excessive growth of the trochanter and shortening of the femoral neck.
