Overall, 7,800 children are diagnosed with hip dysplasia each year in the US. As we know from previous studies of arthritis rates in different age groups, the likelihood and severity of hip dysplasia increases with increasing age. Therefore, this is an opportunity for clinicians to recognize the risk of hip dysplasia in younger children.
The evidence from recent studies suggests that a common cause of hip dysplasia exists on all three anatomical surfaces of the hip. It appears that a genetic predisposition, possibly present in utero, may give rise to dysplasia on at least one of the two acetabular surfaces. Once developed, the dysplasia can spread outward on one of the three hip surfaces, to be followed by further development on the other surface.
Data from a recent study suggests that the abnormal femoroacetabular axis is not cured, and that the final acetabular version of 12° to 14° should be considered a success. We do not feel that the femoral head impingement test could be helpful in this setting.
Treatment of hip dysplasia tends to be less aggressive than other developmental disorders such as Down syndrome. In most cases patients are prescribed physiotherapy to help with movement and exercises to help alleviate pain. In less common cases, a cement hip component is placed which may be removed at the time of surgery. Surgery is usually delayed until the child is between the ages of 5 and 9. There may be some benefit from surgery at this younger age compared to surgery performed later in childhood or adulthood. The decision to operate depends on the child's activity level, ability to wear a hip prosthesis, and the severity of disease. Once a definite diagnosis is made, the child is referred for treatment if it is needed.
Hip dysplasia is a congenital disorder that affects the development of, and results in abnormal growth of, the developing pelvis. It causes pain and physical abnormalities after age 20. Treatment involves an operation, usually by a specialist physician.
Children with signs of hip dysplasia have abnormal hips. The more frequent they are found with, the more frequently they need observation. To facilitate diagnosis, radiographs of the hips should be obtained in all children with signs of hip dysplasia.
The use of intraarticular anesthetics in preoperative procedures for arthroplasty showed no significant effect on pain relief or intra-postoperative analgesic consumption [1.27(-1.16 to 1.33) mg/kg, p =.049]. However, intraarticular analgesia showed a significant relationship with the reduction of morphine consumption [9.4 (-5.4 to -9.8) mg/m2, p =.037].
Results from a recent paper of the latest research in hip dysplasia are still being debated. There are several randomized clinical trials, but there are large discrepancies between the reported results and these discrepancies pose a great problem. However, studies indicate that the current surgical treatment is an effective treatment for most patients who are candidates of surgery but have not developed a pain or discomfort in their hips. A large number of patients who have failed the current treatment may be receiving a less invasive procedure such as an arthroscopy. Although there have been a few unsuccessful surgical procedures that have been performed, an arthroscopic approach carries little risk and results in a successful outcome for most patients.
Treatment of hip dysplasia and associated coxofemoral dysplasia is associated with a significant improvement in patients quality of life and a significant reduction in the severity of pain associated with the condition. Thus, patients who suffer from hip dysplasia for a prolonged period of time are less physically disabled. The present results of these studies provide an update for surgeons and family physicians that the treatment for hip dysplasia has a positive effect on patients QOL.
[For treatment-naive femoral head osteonecrosis patients of subtypes III (A and B) enrolled in the present study, no significant difference was observed in clinical outcomes between the two treatment modalities at 6-month and 24-month follow-up, either without or after adjusting for age and baseline characteristics.] [For treatment-naive femoral head osteonecrosis patients of subtypes III (A and B) enrolled in the present study, no significant difference was observed in MRI osteonecrosis imaging scores between the two treatment modalities at 6-month and 24-month follow-up, irrespective of baseline age age or gender.
In this retrospective study, the odds of being affected by hip dysplasia in siblings of patients with hip dysplasia were more than twice as high as in siblings of patients without hip dysplasia. Therefore, familial screening seems advisable for women of childbearing age who have a history of hip dysplasia.
Overall, the average age, gender, race, and age of the child did not vary by the number of siblings with dysplasia. However, as the dysplasia increased from one family, the average age of the fetus increased from 12.0 to 5 years, the average age when the diagnosis was made increased from 4.5 to 13 years, and the average age of the last patient was 20 years older. When a person has an autosomal recessive genetic condition, the average age of the last affected person is earlier in life. For families with a history of premature ovarian dysfunction or infertility, however, the average age of the last affected person is earlier and often before the first sign of puberty.
