Retrieved from ” https: The acetabulum is the socket-shaped surface of the pelvis where the femoral head sits. The effect is to lengthen the femoral neck. Valgus osteotomy for correction of coxa vara. That is usually the avra article where the information was first stated. Clinically, the condition presents itself as an abnormal, but painless gait pattern. Protrusio acetabuli Coxa valga Coxa vara.
The main indication is improved congruity and reduction of joint forces when the femoral head is not spherical. The blade plate is then secured into place. Femoral deformities can varx arise after treatment of hip dysplasia. The Ganz osteotomy is combined with a capsulotomy and a safe-surgical dislocation of the hip. Contraindications for joint replacement include advanced arthrosis and stiffness.
Correction of the deformity often requires correction in all three planes. Coxa valga leads to acetabular dysplasia.

Vrije Universiteit Brussel Project. Femoral deformity can be secondary to acetabular dysplasia and vice versa. A combined intra-articular and extra-articular impingement of the hip is best addressed with this approach.
Example of normal proximal femoral angles. Coxa vara is usually indicated when valya angle is less than degrees. Stiffness, Pain, Swelling in Joints 1: The most serious ones with high and long term morbidity being osteonecrosis and coxa vara.
Ten years after Nishio varus osteotomy The femoral osteotomy coca be medially translated towards the inside to avoid a secondary translation deformity.
Intra-articular and extra-articular surgical procedures can be performed to correct intra-articular deformities. 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.
Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. The Ganz osteotomy does not actually lengthen the femur, as the Morscher and Wagner approaches do. Deformities of the hip can be divided into coxa valga and coxa vara. Ashish Ranade et al also showed that a varus position of the neck is believed to prevent hip varq associated with femoral lengthening.
Surgery is the most effective treatment protocol.
Deformity of the hip joint may be due to femoral vzra and acetabular dysplasia. CT can be used to determine the degree of femoral anteversion or retroversion.
Signs to look out for are as follows:. Patients may also show femoral retroversion or decreased anteversion.
It is caused by a slipped epiphysis of the femoral head. At the Paley Institute, our approach is to normalize the anatomy and muscle forces while preserving the original anatomic structures. For more information, see Hip Dysplasia Deformities of the hip can be divided into coxa valga and coxa vara.
Toggle navigation p Physiopedia. The Wagner osteotomy is used to change the part of the femoral head that is articulating with the acetabulum. 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.
Valva osteotomy creates a relative lengthening of the femoral neck by shifting the trochanter laterally to the outside and distally downward.

The indication is when there is no need to change the congruity of the joint. Acquired musculoskeletal deformities M20—M25, M95— Using the x-rays, the joint orientation angles of the hip are measured. X-rays provide most of the information needed for diagnosis. It’s assembled with bones that are constantly rebuilding and joints that allow you to move.
