Coxa valga

Normally the angle between the head of femur and shaft is 120° - 135°. An angle above 135° is coxa valga.

Causes:

1)      Skeletal disease (Osteomyelitis, Paget’s disease, Osteogenesis Imperfecta)

2)      Spasticity of adductor muscles of hip

3)      Cerebral palsy (a disorder of movement and or posture as a result of permanent damage to the developing brain. This damage may occur before, during, or immediately after the delivery and has many causes)

4)      Spinal dystrophism (Spina bifida)

5)      Poliomyelitis (an infectious virus disease affecting the CNS. The virus responsible is RNA, transmission through orofaecal, and 90 – 95% polio affected people will not develop polio disease)

Management:

Non surgical:

a.      Physiotherapy:

Aim is stretching the spastic agonist muscles.

b.      Orthotic devices:

These help in maintaining adequate positioning

Surgical:

Valgus osteotomy
