“…Developmental dysplasia of the hip (DDH) is a common musculoskeletal disease. [1][2][3] Infants with DDH often have acetabular dysplasia, which, if uncorrected, can lead to early degenerative joint disease in the long term. Surgical correction of acetabular dysplasia in infants has been widely performed to prevent future osteoarthritis.…”

Plain hip radiograph is commonly used for the diagnosis of infantile acetabular dysplasia. Many infants are unable to maintain adequate position during radiography. Besides, the infantile hip is much smaller and has a higher cartilage component in the acetabulum and proximal femur compared with the adult hip. In this study, we developed a digitally reconstructed radiograph synthesized from magnetic resonance imaging (MRI) and investigated errors of hip radiographic measurements in different pelvic positions. Patients and methods: MRI of both hips was performed in 10 patients (mean age 3.9 years). Three-dimensional (3D) bone models were created from MRI data. We tilted 3D pelvic bone models between 10°anteversion and retroversion and through 10°rotation on the affected and contralateral sides using 3D axes. Following this, we created digitally reconstructed radiographs in each pelvic position and calculated the acetabular index (AI), center-edge angle (CEA), migration percentage (MP), and teardrop distance (TDD). Results: AI tended to increase with pelvic retroversion and did not change with pelvic rotation. CEA tended to decrease with pelvic retroversion and rotation on the contralateral side. MP increased with pelvic retroversion and rotation on the contralateral side. TDD did not change significantly with pelvic tilt and rotation. Conclusions: Radiographic measurements of hip in infants were highly influenced by pelvic movement. AI was influenced by pelvic tilt; CEA and MP were influenced by both pelvic tilt and rotation. We need to keep in mind that infantile hip radiographs could have about ± 5°errors in AI and CEA.

“…The treatment principle for DDH is early diagnosis and early treatment, as this can often mean that less invasive treatment is possible, and outcomes are significantly improved if treatment is initiated at an early stage and certainly before 6 wk of age[ 5 ]. Two to three-year-old children often undergo nonsurgical treatment, with a closed reduction after the use of frog-shaped gypsum or fixation of subbranches.…”

Pelvic osteotomy is commonly used to adjust acetabula dysplasia for congenital dislocation of the hip, whereas congenital insensitivity to pain with anhidrosis (CIPA) is a rare hereditary disease that often has the characteristics of joint development deformity and easy fracture. This article reports the case involving a CIPA patient who was surgically treated by Chiari pelvic osteotomy and proximal femoral rotation osteotomy for congenital dislocation of the left hip joint and was provided long-term follow-up for redislocation and bilateral femoral head absorption.

“…(4,5) The success rate of intervening early with conservative treatment, such as the Pavlik harness, has been reported to be as high as 96.7%, with the rate of avascular necrosis as low as 0%. (6) Such early diagnosis and conservative treatment has been reported to reduce the rate of surgery required for DDH, or even obviate the need for invasive procedures. (7) Rates of all types of open surgery for DDH have been reported to be reduced significantly by effective institutional newborn clinical screening programmes.…”
