COXA VARA

Coxa Vara

Painless limp, LLD gradually worsening , 

Unilateral or bilateral in 30-50 % cases

Prominent trochanters

Pelvic Tilt- LLD 

Trendelenburg test or delaye trendelenburg test + ve

B/L waddling 

High Greater trochnater - supratrochanteric shortening, 

Decreased abduction, (decrease in articular trochanteric distance ) and internal rotation (due to decreased anteversion)

may have out toeing

r/o cervical instability causing limping 

Types of Coxa Vara

Mangement 

    Depends on Hilgenreiner Angle (HEA )

 > 60 degrees - wait and watch 

  45-60 degrees - wait and watch 


Goals of surgery 

    Neck shaft angle  (more or equal ) to 140.              degrees

    Correct version 

    Ossification and healing of inferomedial.               fragment 

    Restore ATD (Articulo-trochanteric       

    distance   AND abductor mechanism

Adductor Tenotomy 

Osteotomy 

  Valgus subtrochanteric osteotomy is the gold standard.But no one method is established the superiority  of one over the other. 

    three types 

    1. Pauwel's Y Subtrochanteric Osteotomy
