Cerebral Palsy Hip Health Related Quality of Life

Study Overview
=================
Brief Summary
-----------------
Children with cerebral palsy are at an increased risk of having their hips move partially or completely out of joint. This can cause pain and restrict movement at the hip, making sitting in a wheelchair uncomfortable and make personal care difficult. This condition may be treated with surgery. Surgeons use x-rays taken before and after the surgery to determine whether or not the surgery has been successful. However, it is also important to know whether the surgery has improved life from the child or the caregiver's point of view. The investigators will also evaluate if waiting for surgery affects the child. This information will be added to results from a physical exam and an evaluation of the child's x-rays for a more complete picture of how this surgery impacts the lives of our patients. It is predicted that that the health-related quality of life of children with cerebral palsy will improve following surgery.

Detailed Description
-----------------
HRQoL will be measured using the Child Health Index of Life with Disabilities (CPCHILD). Our specific hypothesis is that health related quality of life, as measured by the CPCHILD will change by at least a mean of 10 points from pre- to post-surgery.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Cerebral palsy, post hip surgery<br>Children between the ages of 4-18 undergoing surgical treatment for hip subluxation or dislocation secondary to cerebral palsy. | Procedure: Cerebral palsy, post hip surgery<br>* All subjects will undergo surgical treatment for hip subluxation or dislocation.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in quality of life from pre-op to one year post-op | Change in quality of life will be measured by the Caregiver Priorities and Child Health Index of Life with Disabilities questionnaires. | Baseline to 1 year post-op | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in variables obtained from physical and radiological examination | A physical exam includes: child's range of motion at the hip, true hamstring length, tone, Gross Motor Function Classification System level, functional mobility, and pain. Radiological measures include: acetabular index, centre edge angle of Wiberg and shape of head, avascular necrosis of the femoral head, arthritis, pelvic obliquity, Cobb's angle for scoliosis. | Baseline to 1 year post-op |
