Cerebral Palsy Impairments, Assessments, And Interventions For Physical Therapy Practice Exam

Varus Derotation Osteotomy describes a femoral osteotomy aimed at bringing the femoral head into a more contained position within the acetabulum by two components: varus angulation to decrease the outward tilt and derotation to correct excessive femoral anteversion. The osteotomy part means the bone is cut to allow this realignment. This correction is common in cerebral palsy when the hip is unstable or dislocated due to spastic muscle imbalance, improving containment, stabilizing the hip, and facilitating better function. The other options don’t fit: using valgus would move in the opposite direction of the desired containment, a term like dislocation reduction operation isn’t a standard named procedure for this bone cuts and derotation, and vertebral displacement reduction operation refers to the spine, not the hip.
