The shaft of the femur is not moved laterally, however, a major difference with the Morscher osteotomy. Views Read Edit View history. It should not be used for medical advice, diagnosis or treatment. In the case of acquired coxa vara from a fracture, the proximal femur and femoral neck need accurate vqra and rigid fixation to avoid potential serious complications.
Magnetic resonance imaging MRI can be used to illustrate the soft tissues and assess impingement. The other two osteotomies do not change the part of the femoral head that articulates with the acetabulum.
Measuremenst are then taken: There is less danger to the circulation of the femoral head than with the other two approaches because the dislocation helps avoid injury to the femoral head.
What are coxa valga and coxa vara? Correction of coxa valga is a varus osteotomy of the femur.
What are coxa valga and coxa vara?
As always, you should consult with your healthcare provider about your specific health needs. The long axis of the elliptical femoral head is now horizontal. Deformity of the hip joint may be due to femoral coxxa and acetabular dysplasia. This example demonstrates that hip dysplasia can be corrected with osteotomy vaoga the femur and not a pelvic osteotomy. This article does not cite any sources. Pectus excavatum Pectus carinatum.
Coxa vara, on the other hand, produces more amenable forces on the acetabulum.
Intra-articular deformities of the hip are deformities of the femoral head at its connection to the femoral neck. Ashish Ranade et al also showed that a varus position of the neck is believed to prevent hip subluxation associated with femoral lengthening. 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 Therefore, valgus osteotomy needs to translate laterally towards the outside to avoid developing a translation deformity.

This approach has yielded excellent results, extending the life of the hip for our patients while addressing their pain and disability. Coxa Valga Correction of coxa valga is a varus osteotomy of the femur.
Anteversion of the femur inward twisting can create coxa valga.
In some cases, an osteotomy of the iliac wing of the pelvis is performed to shorten the requisite amount for muscle reattachment. The combination of the two techniques results in increased length of the femoral neck.
Hip Preservation | Paley Orthopedic & Spine Institute
This article about a disease of musculoskeletal and connective tissue is a stub. The femoral osteotomy should be medially translated towards the inside to avoid a secondary translation deformity. Arthrogryposis Larsen syndrome Rapadilino syndrome. Femoral deformity can be secondary to acetabular dysplasia and vice versa.
Coxa valga – Wikipedia
This results in further deformity, such as coxa breva shortening of the neck of the femur valgga collapse of the femoral head, resulting in an elliptical or saddle shape. Our approach is to perform the osteotomy distal down to the lesser trochanter to minimize tension on the psoas tendon. A Trendelenburg limp is sometimes associated with unilateral coxa vara and a waddling gait is often seen when bilateral coxa vara is present.
The main indication is improved congruity and reduction of joint forces when the femoral head is not spherical. One example of coxa vara with hip dysplasia is in Congenital Femoral Deficiency. Femoral deformity and acetabular dysplasia are often associated with each other.
