Background: Although the developmental dysplasia of the hip (DDH) is well known to pediatric orthopedists, its etiology has still remained unknown and despite dedication of a vast majority of research, the results are still inadequate and confusing. The exact incidence of DDH and its relationship with known risk factors in Iran is still unknown. Here we represent the results of one year study on the incidence and related conditions of DDH. Methods: Sonography was performed on the hip joints of 1073 full term healthy newborns at Imam Khomeini Hospital from March 2013 to March 2014...

BACKGROUND: We argue that 1-stage bilaterally total hip arthroplasty (THA) could be acceptable in bilateral coxarthrosis because of high-riding developmental dysplasia of the hip (DDH). METHODS: Sixty-nine cases (51 patients) of high-riding DDH in patients who underwent THA from 2010 to 2013 were reviewed. Patients were divided into 2 groups: unilateral (group 1) and 1-stage bilateral surgery (group 2). The clinical measurements were the visual analog scale and Harris Hip Score...

PURPOSE: To investigate the arthroscopic pathoanatomy of the transverse acetabular ligament (TAL) and determine whether a TAL incision is necessary for the concentric reduction of developmental dysplasia of the hip (DDH) in infants and young children. METHODS: We retrospectively reviewed patients who underwent arthroscopic-assisted reduction for DDH between July 2008 and April 2016. The indications for this intervention included patients in whom closed reduction failed and those who did not require bone operations...

PURPOSE: Our objective was to find the best predictor of late residual acetabular dysplasia in developmental dysplasia of the hip (DDH) after closed reduction (CR) and discuss the indications for secondary surgery. METHODS: We retrospectively reviewed the records of 89 patients with DDH (mean age 16.1 ± 4.6 months; 99 hips) who were treated by CR. Hips were divided into three groups according to final outcomes: satisfactory, unsatisfactory and operation. The changes in the acetabular index (AI), centre-edge angle of Wiberg (CEA), Reimer's index (RI) and centre-head distance discrepancy (CHDD) over time among groups were compared...

Background Patients with developmental dysplasia of the hip (DDH) may have decreased blood supply to the femoral heads. Finding a non-invasive method to evaluate whether the femoral heads in patients with DDH are ischemic is paramount for orthopedic surgeons. Purpose To identify whether parameters reflecting perfusion and diffusion in intravoxel incoherent motion (IVIM) sequences can be used to assess ischemia in femoral heads in patients with DDH after closed reduction. Material and Methods Twenty-eight patients with DDH who had undergone closed reduction were enrolled...

Redirective, periacetabular osteotomies (PAO) represent a group of surgical procedures for treatment of developmental dysplasia of the hip (DDH) in skeletally mature and immature patients. The ultimate goal of all procedures is to reduce symptoms, improve function and delay or prevent progression of osteoarthritis. During the last two decades, the understanding of the underlying pathomechanisms has continuously evolved. This is mainly attributable to the development of the femoroacetabular impingement concept that has increased the awareness of the underlying three-dimensional complexity associated with DDH...

PURPOSE: In total hip arthroplasty, prediction of the optimal implant size is important in order to prevent perioperative complications. However, it is not easy to achieve complete agreement between the planned size and the actual size required appropriate implant fit. No previous report has adequately discussed the factors related to mismatch between predicted and actual implant sizes. The purpose was to report the results of a single surgeon case series of patients undergoing THA using computed tomography (CT)-based templating and the possible factors related to implant size mismatch...

Spondyloepimetaphyseal dysplasia with joint laxity type 1 (SEMDJL1) is a rare entity with a recessive inheritance. In this report, we describe 3 affected members of the same family who present with short stature, hyperlaxity with secondary spinal malalignment, ulnar subluxation, developmental dysplasia of the hips, and craniofacial alterations; one member also had learning difficulties. DNA analysis showed compound heterozygous variants in the B3GALT6 gene (c.901_921dup, c.511C>T) in all 3 patients, inherited from the parents...

Developmental dysplasia of the hip (DDH) in humans is a common condition that is associated with hip pain, functional limitations, and secondary osteoarthritis (OA). Surgical treatment of DDH has improved in the last decade, allowing excellent outcomes at short- and mid-term follow-up. Still, the etiology, mechanobiology, and pathology underlying this disease are not well understood. A pre-clinical animal model of DDH could help advance the field with a deeper understanding of specific pathways that initiate hip joint degeneration secondary to abnormal biomechanics...

Jay H Patel, Berton R Moed
BACKGROUND: Exact determinants of hip instability have not been established for fractures of the posterior wall of the acetabulum involving ≤50% of the wall. Therefore, examination of the hip under anesthesia (EUA) is routinely performed. Recently, the superior exit point of the fracture has been reported to be an important identifiable risk factor. Pre-existing adult hip dysplasia (developmental dysplasia of the hip [DDH]) is thought to have a similar role. The purpose of this study was to determine if any known radiographic measurements and signs associated with DDH, or any fracture characteristics, are independent risk factors for hip instability after fracture of the posterior wall of the acetabulum...

Background: Developmental hip dysplasia is diagnosed when the femoral head is not sufficiently covered by the acetabulum. Anterior and lateral cover deficiency is seen, as a result a dysplastic hip joint. Various incision modifications have been developed because of the muscle dissection and wide wound scar in Smith-Peterson incision, which was originally used in Bernese osteotomy. This study evaluates applicability of the modified Stoppa approach in the performance of Bernese periacetabular osteotomy (PAO)...

BACKGROUND: Prune belly syndrome is a rare congenital malformation of unknown etiology, with the following triad of findings: abdominal muscle wall weakness, undescended testes, and urinary tract abnormalities. In most cases, detection of prune belly syndrome occurs during neonatal or infancy period. In this case report, we describe a 12-year-old boy from Ethiopia with the triad of findings of prune belly syndrome along with skeletal malformations. We are unaware of any previous report of prune belly syndrome in Ethiopia...

PURPOSE OF REVIEW: Our understanding of the epidemiology, diagnosis, and management of developmental dysplasia of the hip (DDH) is evolving. This review focuses on the most up-to-date literature on DDH in patients from birth to six months of age. RECENT FINDINGS: Well known risk factors for DDH include family history, female sex, and breech positioning. Recent evidence suggests higher birth weight is a risk, whereas prematurity may be protective. Screening includes physical examination of all infant hips and imaging when abnormal findings or risk factors are present...

The treatment of developmental dysplasia of the hip (DDH) in children remains controversial. We describe the clinical and radiological outcomes of  47 hips in 43 children treated with open surgery by one surgeon between 2004 and 2008 for DDH. The mean age at operation was 25 months (5 to 113) with a mean follow up of  89 months  (22 to 169). At the latest follow up 40 of the 45 hips where Severin grades were recordable (89%) were graded as excellent or good, Severin class I or II. Clinically significant AVN (grade II to III  according to the Kalamchi and MacEwen classification) was seen in 6  (13%) of the hips...

INTRODUCTION: The anatomic abnormalities in developmental dysplasia of hip (DDH) often make total hip replacement (THR) inevitable at a younger age. However, there is no universal gold standard technique of THR for high dislocated dysplastic hips. MATERIALS AND METHODS: Here we present the outcomes of midterm follow-up after THR in patients diagnosed with DDH Crowe type III and IV hospitalized in a tertiary center in Iran for whom placement of a cup in true acetabulum and selective transverse subtrochanteric osteotomy was performed...
