Cerebral palsy is described as a set of permanent disorders of development, movement and posture leading to limited activity levels, caused by non progressive disturbances in development of fetal and infant brain resulting in UMN lesion. The incidence accounts to 3 per 1000 live births and prevalence 2.4 per 1000 children and has a slight male preponderance. Which is characterized by spasticity weakness and impaired selective motor control with time, majority of children develop a spectrum of secondary problems, collectively referred to as “progressive musculo skeletal pathology”. Single–event multi level surgery (SEMLS) can improve gait and functioning in children with Cerebral palsy in one session. The operative procedures comprise the correction of fixed contractures by muscle recessions and tendon lengthening, addressing muscle imbalance with tendon transfers, correction of bony deformities and joint stabilization procedures. The present study was to evaluate the results of SEMLS in the lower limbs of patients with spastic diplegic CP during follow–up appointments 12–24 months after surgery.
