Neck of femur stress fracture malunion - Ganzer Fall bei Radiopaedia
Coxa vara describes a deformity of the hip where the femoral neck-shaft angle is decreased, usually defined as less than 120 degrees.
Pathology
It can be congenital or acquired. The common mechanism in congenital cases is a failure of medial growth of the physeal plate .
Classification
One of the very early classifications proposed by Fairbank in 1928, is often considered most useful from a radiologic point of view. A slight modification of this system includes:
- idiopathic:
- congenital: mild or severe coxa vara, with associated congenital anomalies: see associations
- developmental: progressive, usually appearing between the ages of two and six years, with characteristic radiographic features
- rachitic: usually associated with active rickets
- adolescent: secondary to the slipped capital femoral epiphysis
- traumatic: usually following fracture of the femoral neck (rare in children)
- inflammatory: secondary to tuberculosis or other infection
- secondary to other underlying bone diseases such as:
- capital coxa vara: occasionally seen in severe osteoarthritis and Legg-Perthes' disease
Associations
- congenital dislocation of hip - developmental hip dysplasia
- faulty development of the femur
- craniocleidodysostosis
- camptodactyly arthropathy coxa vara pericarditis (CACP) syndrome
