At the Paley Institute, our approach is to normalize the anatomy and muscle forces while preserving the original anatomic structures. In the case of acquired coxa vara from a fracture, the proximal femur and femoral neck valgaa accurate reduction and rigid fixation to avoid potential serious complications.
That is usually the journal article where the information was first stated. Deformities of the hip can be divided into coxa valga and coxa vara.
What are coxa valga and coxa vara? | Bone & Joint Conditions – Sharecare
CT can be used to determine the degree of femoral anteversion or retroversion. Treatment involves a pelvic osteotomy combined with varus osteotomy at the upper femur. Computerized tomography CT may be useful to evaluate the shape of the femoral head and acetabulum. Vra example is a deformity of the shape of the femoral head.
The other two osteotomies do not change the part of the femoral head that articulates with the acetabulum. 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. These must be addressed during surgery with soft tissue releases. This osteotomy creates a relative lengthening of the femoral neck by shifting the trochanter laterally to the outside and distally downward.
Lateral translation occurs by lining up the blade plate along the femur.
Intra-articular and extra-articular surgical procedures can be performed to correct intra-articular deformities. The center of rotation of angulation CORA is at the center of the femoral head.
Coxa vara results from previous treatment or a congenital deformity. As a result of congenital coxa varathe inferior medial area of the femoral neck may be fragmented. The main indication is improved congruity and reduction of joint forces when the femoral head is not spherical.
Acetabular dysplasia and femoral anteversion are usually associated vakga one another. Prevention is always optimal, but when problems occur, treatment might involve weight-bearing exercise, dietary changes, exercise, medical treatments and possibly surgery.
This article does not cite any sources. The more extreme and the more chronic a hip deformity, the more likely there are to be associated soft tissue contractures.
Coxa Vara / Coxa Valga
If the angle is less than degrees, this is considered to be coxa vara. The greater trochanter is lateralized, increasing abductor lever arm.
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. There is a risk that the greater trochanter may lose both tension and lever arm, which can lead to a lurch or Trendelenburg gait. For more information, see Slipped Capital Femoral Epiphysis. Ashish Ranade et al also showed that a varus position of the neck is believed to prevent hip subluxation associated with cxa lengthening.

Stiffness, Pain, Swelling in Joints 1: Luxating patella Chondromalacia patellae Patella baja Patella alta. The evaluation will include hip range of motion ROMassessment of hip impingement, rotation profile of the femur and tibia, hip flexion and abduction strength, and pain.
Correction of the deformity often requires correction in all three planes. Coxa valga and coxa vaga are deformities of the hip. It is caused by a slipped epiphysis of the femoral head. Because of this, consideration of the muscles of the hip and upper femur is crucial to avoid developing further complications. Signs to look out for are as follows:.
