Objective: The aim of this study was to document rate of survival among 288 severely affected pediatric patients with spasticity and neuromuscular scoliosis who underwent spinal fusion and to identify exposure variables that could significantly predict survival times.

Methods: Kaplan-Meier survivorship analysis was performed and Cox’s proportional hazards model was used to evaluate predictive efficacy of exposure variables such as gender, age at surgery, level of ambulation, mental ability, degree of coronal and sagittal plane spinal deformity, intraoperative blood loss, surgical time, days in the hospital, and days in the intensive care unit (ICU).

Results: The statistical analysis demonstrated a mean predicted survival of 134.3 months (11.2 years) after surgical correction of spinal deformities for this group of globally involved children with cerebral palsy. The number of days in the ICU after surgery and the presence of severe preoperative thoracic hyperkyphosis were the only factors affecting survival rates. ICU stay of greater than five days, which was usually associated with respiratory problems, substantially increasing the risk of death. Thoracic hyperkyphosis of greater than 70o caused a considerable increase in the predicted mortality rate.

Conclusions: Our study demonstrated a relatively long mean predicted survivorship for pediatric patients with severe spastic cerebral palsy and neuromuscular scoliosis who underwent spinal surgery, which is consistent with the current concept of increased life expectancy even for the total-body involved patients. The most accurate determinants for survival rates among this population group were the number of days the patient had to spend postoperatively in the intensive care unit, and the presence of excessive preoperative thoracic hyperkyphosis.

The number of days in the ICU after surgery and the presence of severe pre-operative thoracic hyperkyphosis were the only factors affecting survival rates. ICU stay of greater than five days, which was usually associated with respiratory problems, substantially increasing the risk of death. Thoracic hyperkyphosis of greater than 70° caused a considerable increase in the predicted mortality rate.

Purpose. The aim of this study was to document rate of survival among 288 severely affected pediatric patients with spasticity and neuromuscular scoliosis who underwent spinal fusion and to identify exposure variables that could significantly predict survival times.

Methods. Kaplan-Meier survivorship analysis was performed and Cox’s proportional hazards model was used to evaluate predictive efficacy of exposure variables such as gender, age at surgery, level of ambulation, mental ability, degree of coronal and sagittal plane spinal deformity, intraoperative blood loss, surgical time, days in the hospital, and days in the intensive care unit (ICU).

Results. The statistical analysis demonstrated a mean predicted survival of 134.3 months (11.2 years) after spine surgery for this group of globally involved children with cerebral palsy (Figure 1). The number of days in the ICU after surgery and the presence of severe preoperative thoracic hyperkyphosis were the only factors affecting survival rates. ICU stay of greater than five days, which was usually associated with respiratory problems, substantially increased the risk of death. Thoracic hyperkyphosis of greater than 70° caused a considerable increase in the predicted mortality rate.

Conclusions. Our study demonstrated a relatively long mean predicted survivorship for children and adolescents with severe spastic cerebral palsy and neuromuscular scoliosis who underwent spine surgery, which is consistent with the current concept of increased life expectancy even for the total-body involved patients.

The most accurate determinants for survival rates among this population group were the number of days the patient had to spend postoperatively in the intensive care unit, and the presence of excessive thoracic hyper-kyphosis.
