What are the advantages associated with Coxa Vara?
|
The moment arm for the hip abductors is increased, improved joint stability
|
|
|
|
What are the advantages associated with Coxa Valga?

Increased shear forces across the femoral neck, the length of the abductors is decreased
|
|
|
|
What are the disadvantages of Coxa Valga?
|
The moment arm for the hip abductors is decreased, diminished joint stability
|
|
|
|
What abnormal alignments accompany coxa vara?
|
Valgus at the knee, internal rotation of the tibia and excessive pronation at the subtalar joint.
