As noted above, breech presentation may be the most important single risk factor, with DDH reported in 2 to 27% of males and females presenting in the breech position. [uwhealthkids.org]
In the present study, DDH was more common among girls (85.8%) with a male to female ratio of 1:6. [thejhs.org]

Nearly all babies who are diagnosed with DDH go on to have a healthy, active life, with no disability. [nct.org.uk]
Avascular necrosis (AVN) is considered to be the most significant complication following treatment for DDH because of the consequent early onset of progressive osteoarthritis, disability and the need for total hip arthroplasty at a young age [ 6 ]. [link.springer.com]
- Difficulty Walking
This can lead to: A shortened leg Arthritis Difficulty walking Long-term pain Symptoms In an infant, developmental dysplasia of the hip can result in the following: One leg is shorter than the other. [drugs.com]
If cases of congenital hip dysplasia go untreated, the child will have difficulty walking, which could result in life-long pain. [medical-dictionary.thefreedictionary.com]
If left untreated, the child will have difficulty walking and may experience life-long pain. If diagnosed early, congenital hip dysplasia treatment is highly effective. [healthofchildren.com]

Congenital hip dislocation (CHD) occurs when a child is born with an unstable hip. It’s caused by abnormal formation of the hip joint during their early stages of fetal development. [healthline.com]

This should not be confused with high pitched hip clicks often elicited with hip flexion and extension. [uwhealthkids.org]
In children with arthrogryposis or skeletal dysplasias, confusion can occur due to difficulty in determining the normal landmarks of the proximal femur. [ijri.org]

Prognosis
The satisfactory prognosis associated with early treatment of severe congenital dislocation of the hip joint underlines the advisability of scheduling routine hip screening programs to ensure early diagnosis and effective treatment of the disorder. [ncbi.nlm.nih.gov]
In individuals for whom the diagnosis is made later, the prognosis is not as positive. These children may require more extensive surgery. After surgery, however, the prognosis for normal development of the hip and leg is excellent. [healthofchildren.com]
[…] age 3 months, the deformity is expected to persist without treatment; - type III: dislocation - acetabulum is shallow; - cartilaginous roof is displaced with eversion of labrum; - type IV: high dislocation - acetabular cup is flat and has the worse prognosis [wheelessonline.com]

Prevention
The primary goals of treatment for Perthes disease are to alleviate pain and to prevent lasting deformity of the femoral head. [scottishritehospital.org]
The goal, though, is to prevent these signs from manifesting by correcting DDH in early childhood. [pedclerk.bsd.uchicago.edu]
Prevention Prevention includes proper prenatal care to determine the position of the baby in the womb. This may be helpful in preparing for possible breech births associated with hip problems. [healthofchildren.com]
Avoiding excessive and prolonged infant hip adduction may help prevent strain on the hip joints. Early diagnosis remains an important part of prevention of congenital hip dysplasia. [medical-dictionary.thefreedictionary.com]
