There are over 50 million disabled people in Africa. 18-20% would likely improve with some surgical care. Africa has insufficient surgical expertise to provide for this need, and will likely not have sufficient sub specialists for 50-100 years. An alternate form of limited training is needed both for the surgical and the support needs of the disabled.
Care for the disabled opens spiritual doors for both the child and the parents. It may also open doors into traditionally "closed" countries.
