The acetabulum is the socket-shaped surface of the pelvis where the femoral head sits.
Coxa vara is usually indicated when the angle is less than degrees. In this case study, the acetabulum is abnormal in coxa vara. This human musculoskeletal system article is a stub.
This will result in good stabilization of the hip. Example of normal proximal vlaga angles. It should not be used for medical advice, diagnosis or treatment.
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. Wagner Osteotomy The Wagner osteotomy is used to change the part balga the femoral head that is articulating with the acetabulum.
Contents Editors Categories Share Cite. Femoral deformity can be secondary to acetabular dysplasia and vice versa. A review on the development va,ga coxa vara by Currarino et al showed an association with spondylometaphyseal dysplasia, demonstrating that stimulated corner fractures were present in most instances.
December Learn how and when to remove this template message. Acquired musculoskeletal deformities M20—M25, M95— When refering to evidence in academic writing, you should always try to reference the primary original source. Hip, Groin, or Buttock Problem. Valgus osteotomy for correction of coxa vara.
Coxa Vara / Coxa Valga
This page was last edited on 1 Aprilat This osteotomy creates a relative lengthening of the femoral neck by shifting the trochanter laterally to the outside and distally downward.
Valgus angles greater than degrees put the patient at risk of hip subluxation dislocation. Patients may also show femoral retroversion or decreased anteversion. The center of rotation of angulation CORA is at the center of the femoral head. These deformities occur when the angle formed by the valfa of the femur and the shaft of the femur is abnormal.
You can help Wikipedia by expanding it. Lateral translation occurs by lining up the blade plate along the femur. 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. Winged scapula Adhesive capsulitis Rotator cuff tear Subacromial bursitis.
The approach is really two osteotomies: Unsourced material may be challenged and removed. The Nishio osteotomy at the base of the neck. A – Congenital short femur with coxa vara and overgrown trochanter.
The osteotomy is performed and the bone corrected to the desired position. There is a risk that the greater trochanter may lose both tension and lever arm, which can lead to a lurch or Trendelenburg gait.
Another example is a non-spherical femoral head can be treated by a Ganz femoral head reduction osteotomy FHRO.
Coxa Vara / Coxa Valga – Physiopedia
Furthermore, the shape of the valfa femur is affected by any imbalance of muscle forces around it. Our approach is to perform the osteotomy distal down to the lesser trochanter to minimize tension on the psoas tendon. Physiopedia articles are best used to find the original sources of information see the references list at the bottom of the article.
We developed a method called fixator-assisted nailing in which the deformity is first stabilized with an external fixator, and then with internal fixation.
The greater trochanter is lateralized, increasing abductor lever arm. For more information, see Hip Dysplasia Deformities of the hip can be divided into coxa valga and coxa vara. Coxa valga is more common in xoxa.
Coxa valga – Wikipedia
The femoral osteotomy should be medially translated towards the inside to avoid a secondary translation deformity. In other projects Wikimedia Commons.
To avoid this, we will transfer the greater trochanter at the same time as the osteotomy. There are 3 types Coxa Vara, acquired, congenital and developmental, usually displaying greater acetabular dysplasia and an abnormal acetabulum. The main indication is improved congruity and reduction of joint forces when the femoral head is not spherical.
