By the 3-year follow-up, the the hip reduced and she developed a fixed posterior dis- hip remodeled and she was stable and pain free (Figure location (Figure C10. For this reason, we have tried to keep these children in either in- ternally rotating orthotics or have asked parents to keep their children’s legs together to prevent them from lying with their lower extremities in the ab- ducted, externally rotated position. Complications The major complication of a type III anterior dislocation is that a recurrent dislocation will occur. If children are ambulators, it is reasonable to make a second attempt to get the hip reconstructed. Hip 593 one child in whom a second acetabular reconstruction was required; this was successful in maintaining the hip reduced and keeping the child walking until she became a young adult. We anticipate, although we have no experi- ence, that these individuals should maintain stable hip joints once they reach full adulthood. Inferior Hip Dislocation Direct inferior dislocations of the hip are very rare. We have only treated one such deformity and have had the opportunity to examine another patient (Case 10. Both these individuals had tremendous difficulty with seating because their legs were fixed in a severe, abducted hip and knee-flexed posi- tion making seating almost impossible. A hip radiograph showed inferior hip sub- had a tracheal diversion. A redirectional varus femoral because of difficulty sitting and a complaint from the osteotomy did not greatly change the hip position but al- mother that he sometimes got his knee stuck in his axilla lowed easier sitting and lying in a more normal position when lying. On physical examination he had fixed hip (Figure C10. Our single treatment experience with this type of inferior dislocation is a varus repositioning os- teotomy that allowed this individual to sit much better. The hip did not be- come painful, although this child had severe neurologic involvement that required a tracheostomy. Six years after the varus osteotomy, this child died of aspiration through his tracheal diversion. Hyperabducted and Extended Hip Deformities A small group of children develop severe, bilateral abducted hips. Some of the children have extension contractures and have more or less flexion. This deformity creates great difficulty with seating88 and is a very socially un- appealing posture for adolescents and young adults (Case 10. Etiology There are children in whom the etiology of this hyperextended and abducted position is iatrogenic, related to too much adductor and iliopsoas lengthening with obturator neurectomies. Another large group of children develop this deformity unilaterally and it be- comes a windblown hip posture. The natural history of this hyperabduction deformity is not well docu- mented; however, in our experience, it generally does not get progressively worse as children get older. The problem occurs as children get older and bigger, making it more difficult to accommodate the deformity. With some attention to seating modifications, many of these children develop good pat- terns of sitting and can often spend long periods of time lying in a side lying position. This deformity is a very cosmetically objectionable posture, espe- cially for adolescent and young adult females, to be lying in the hyperab- ducted hip-flexed position every time they are not sitting in their wheelchairs. Some of the children and many caretakers are bothered by this posture. Although it seems that this posture is a precursor to the type II anterior hip dislocation, no good documentation exists to suggest that it leads directly to anterior hip dislocation or inferior hip dislocation. This evolution of defor- mity may occur, but is so rare that it is not recognized as part of the precur- sor posture. A much more common bony deformity that occurs from this position as children grow, and especially as they go into adolescence, is the development of protrusio acetabuli from too much direct medial pressure. This is exactly opposite of what is seen when the widened teardrop with an- terior or posterosuperior dislocations are present.

Therefore, the goal of allowing the individual with cerebral palsy to live life with the least impact of the disability requires com- plex attention to the individual and the family. Furthermore, society needs to be sensitive and to accommodate individuals with disabilities by limiting architectural impediments and providing accessible public transportation and communication. The educational system provides the key means for helping the individual prepare to function in society to his or her maximum ability. In many ways, the medical care system probably has the least signif- icant role in preparing the child with cerebral palsy to function optimally in society. However, the medical care system is the place where parents first learn that their child has developmental issues outside the expected norm. It is almost universally the place where parents also expect the child to be made normal in our modern society. In earlier times, the parents would expect healing to possibly come from the doctor, but also they would place hope for healing in religion. As this belief in spiritual or miraculous healing has de- creased, a significant font of hope has decreased for parents of young chil- dren with disabilities. The text aims to help the child with cerebral palsy to develop into an adult in whom the effects of the disability are managed so that they have the least impact possible on adult function. This intention is in the context of the fact that the magnitude of improvement in the disability that occurs with ideal management of the musculoskeletal system during growth may be only a small improvement. Probably the more significant aspect of good muscu- loskeletal management through childhood is helping the child and family to maintain realistic hope for the successful adult life of the growing child. This aim requires the medical practitioner to get to know the child and family and to communicate in a compassionate way realistic expectations of the child’s function. For many reasons, the greatest difficulty in providing this kind of care is the limited time practitioners have to spend with the individual pa- tient. There is also the sense, especially among orthopedic physicians, that cerebral palsy cannot be cured (cannot make the child function normally), and thus it is a frustrating condition with which to work. The physician must maintain a balance between communicating hopelessness to the patient and family; and feeling the need to do something, usually a heel cord lengthening, because the parents are frustrated that the child is not progressing. All med- ical decisions, including a surgical option, should always consider both the short- and long-term impact. With every decision the medical practitioner should ask, “What will be the impact of this recommendation by the time the child is a mature adult? This text is intended to pro- vide this insight as much as possible. Another issue is the poor scientific documentation of natural history and treatment response in cerebral palsy, which has become clearer to me in the course of writing this book. With little scientifically based natural history and few long-term studies, much of what is written in this text is expert- based observation. The goal of writing this is not to say that it is absolute fact, but to provide the starting point of gathering information with the hope that others will be stimulated to ask questions and pursue research to prove or disprove the concepts. The research, which is of help in treating children with cerebral palsy, needs to be planned and evaluated with consideration of its long-term im- pact on the child’s growth and development. All treatment should also con- sider the negative impact on the child.
