Congenital Hip Dysplasia

CASE: We describe the surgical management of a girl with dwarfism and congenital spondyloepiphyseal dysplasia, who presented in adolescence with coxa vara and bilateral pseudarthrosis between the femoral neck and the diaphysis, with asymmetric distal migration at both sites and leg length discrepancy. The patient at 16 years underwent valgus osteotomy in situ and femoral neck fixation in the left hip. The right hip was operated 19 months later. CONCLUSION: Hip dysplasia is common in spondyloepiphyseal dysplasia, but a debilitating nontraumatic bilateral pseudarthrosis at the base of the femoral neck has not been previously reported...

The acetabular bone defect reconstruction is of great challenge in total hip arthroplasty (THA). Although several solutions such as autologous bone grafting, trabecular metal augment, or compromising techniques such as the medial protrusion, high inclination angle, and elevated hip center have been raised, their efficacy and reliability have not been fully substantiated. Traditional reconstruction methods may lead to bone resorption, aggravation of bone defects, unequal length of lower limbs, unbalance of hip-spine relationship, increased costs, and so on...

Trichohepatoneurodevelopmental syndrome is an extremely uncommon autosomal recessive disorder resulting from variants in the CCDC47 gene, which encodes a Ca2+ -binding endoplasmic reticulum (ER) transmembrane protein. To date, only four patients with CCDC47 deficiency have been reported, all of them with homozygous truncating CCDC47 variants. For this study, a Chinese family was recruited, which included a patient diagnosed with trichohepatoneurodevelopmental syndrome. Whole exome sequencing (WES) identified the proband's novel homozygous CCDC47 variation (NM_020198: c...

Congenital dislocation of the hip is a malformation of the lower limbs that could be complicated by a disabling physical handicap with long-term psychological and social repercussions if detected late. This study aims to describe the screening for congenital hip dislocation and to investigate the association between the occurrence of this anomaly and possible risk factors in Morocco. The study was based on the exploitation of the records of children treated at the trauma and orthopedics department of the Mohammed VI University Hospital in Marrakech, Morocco...

BACKGROUND: Developmental dysplasia of the hip (DDH) affects 1-3% of newborns and 20% of cases are bilateral. The optimal surgical management strategy for patients with bilateral DDH who fail bracing, closed reduction or present too late for these methods to be used is unclear. There are proponents of both medial approach open reduction (MAOR) and anterior approach open reduction (AOR); however, there is little evidence to inform this debate. METHODS: We will perform a systematic review designed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol...

Pierre Robin sequence is a rare congenital disorder with variable associations. A two-year-old female child was brought in with complaints of an abnormal gait and right lower limb shortening. A comprehensive clinical evaluation unveiled facial characteristics resembling those of Pierre Robin Sequence, including micrognathia, a cleft palate, and glossoptosis. The child also exhibited retrognathia, a low posterior hairline, bilateral developmental dysplasia of the hips, right foot syndactyly, and a left ectopic kidney as confirmed by ultrasonography...

Intrapelvic acetabular cup migration is a rare but serious complication that can occur following either primary or revision total hip arthroplasty. Medial acetabular wall weakening is considered the main predisposing factor for acetabular protrusion. A thorough preoperative plan is essential to advocate proper pelvic anatomy reconstruction, including osteosynthesis of the pelvis, if necessary, preservation of muscle and bone stock, and selection of the right prosthetic components without damaging adjacent anatomical structures...

Metallosis with subsequent cardiac involvement is a possible long-term complication of hip arthroplasty. We report the case of a young female referred to our centre for the suspicion of cardiac amyloidosis presenting with low electrocardiogram voltage, left ventricular hypertrophy, pericardial effusion, and global and longitudinal systolic impairment with apical sparing pattern. Her medical history was remarkable for arthroplasty in the context of congenital hip dysplasia. Two years prior to presentation, she underwent revision surgery for prosthesis malfunction, and tissue metallosis was initially documented...

OBJECTIVE: Developmental dysplasia of the hip (DDH) is a congenital condition affecting 2-3% of all infants. DDH increases the risk of osteoarthritis, is the cause of 30 ​% of all total hip arthroplasties (THAs) in adults <40 years of age and can result in loss of life quality. Our aim was to explore the genetic background of DDH in order to improve diagnosis, management and longterm outcome. DESIGN: We used the large, ongoing, longitudinal Trøndelag Health Study (HUNT) database...

BACKGROUND: Hip dysplasia is one of the most prevalent disorders in children and one of the three primary congenital orthopedic deformities. Although there are numerous existing methods (e.g., CT, MRI and arthrography) for early identification of hip dysplasia, their diagnostic criteria differ widely. It is critical to establish a safe, accurate, and reliable way for early diagnosis and treatment of hip dysplasia. OBJECTIVE: This study aimed to analyze the diagnostic efficacy of high-frequency ultrasound (HFU) for congenital developmental hip dysplasia and hip dislocation and to provide a reference for the early diagnosis of congenital hip dysplasia in the future...

Developmental dysplasia of the hip is the cause of approximately one third of secondary coxarthrosis. Anatomy alterations make it difficult to place a total hip prosthesis in its anatomical position and for it to be stable in the long term; there are several techniques to achieve this goal. In the present work, we used autograft of the femoral head (shelf graft or reinforced roof), to improve the coverage of the acetabular component with favourable results. Materials ad methods Sixteen cases were included in 14 patients with a diagnosis of developmental dysplasia of the hip (13 women and one man), the mean age was 44...

OBJECTIVE: The choice approach to treating congenital dislocation of the hip joint is total hip replacement (THR). One of the severe but uncommon complications of THR is nerve damage. The most common nerve injury associated with total hip arthroplasty (THA) is sciatic nerve palsy, and the second typical nerve damage with THA is femoral nerve paralysis. PATIENTS AND METHODS: In this prospective cohort study, 35 patients with type 4 high riding developmental dysplasia of the hip (DDH) who were candidates for THA were enrolled...

INTRODUCTION: Congenital muscular torticollis (CMT) is an asymmetrical head position resulting from structural changes in the sternocleidomastoid (SCM) muscle that occurs early during a child's development or due to perinatal trauma. Children with CMT exhibit a marked imbalance in tension between the SCMs. In a typical clinical picture, an ultrasound scan is performed to reveal characteristic lesions, such as tissue fibrosis or post-traumatic changes. An early diagnosis of CMT in newborns and the implementation of treatment offer the chance of a complete resolution...

A lumbosacral transitional vertebra (LTV) is a congenital anomaly of the spine and has been suggested to predispose to canine hip dysplasia (CHD). This retrospective, cross-sectional study investigated the prevalence of LTV and CHD among 14 dog breeds in Norway, the possible associations with risk factors, and whether LTV was a risk factor for the development of hip dysplasia. The results were based on evaluation of ventrodorsal radiographs from the CHD screening program from the Norwegian Kennel Club from February 2014 to January 2022...

Developmental dysplasia of the hip (DDH) is a condition characterized by changes in joint formation within the last months of intrauterine life or the first months after birth. Developmental dysplasia of the hip presentation ranges from femoroacetabular instability to several stages of dysplasia up to complete dislocation. Early diagnosis is essential for successful treatment. Clinical screening, including appropriate maneuvers, is critical in newborns and subsequent examinations during the growth of the child...

BACKGROUND: Established associated factors for DDH include female sex, breech presentation, family history, congenital malformations, oligohydramnios, and maternal hyperthyroidism. However, evidence for environmental factors that may contribute to DDH is limited and inconsistent. METHODS: A systematic review of medical literature was conducted to collect data on environmental factors, including latitude, longitude, average yearly precipitation, average yearly temperature, minimum monthly temperature, and maximum monthly temperature, from all institutions that published articles on DDH...

A 28-year-old woman with a history of congenital hip dysplasia was referred for evaluation of recurrent bronchitis. She had undergone left hip replacement with titanium implants 11 years prior to presentation. The patient reported frequent bouts of bronchitis, sinusitis, and left-sided nontender facial swelling that started after the hip replacement surgery. She also reported nail discoloration of her left first toenail 1 year after this procedure, and nail discoloration of her right first toenail 3 years after the procedure...

BACKGROUND: Multiple epiphyseal dysplasia (MED) is a rare congenital bone dysplasia. Patients with MED develop secondary hip osteoarthritis as early as the third to the fourth decade. Currently, there is no consensus on the prevention of the progressive hip osteoarthritis secondary to MED. The Bernese periacetabular osteotomy (PAO) is a joint-preserving surgery to reshape acetabulum and extend femoral head coverage. However, there is no documentary evidence for the effect of the procedure on MED hips...

Axenfeld-Rieger anomaly (ARA) is a specific ocular disorder that is frequently associated with other systemic abnormalities. PITX2 and FOXC1 variants explain the majority of individuals with Axenfeld-Rieger syndrome (ARS) but leave ~30% unsolved. Here, we present pathogenic/likely pathogenic variants in nine families with ARA/ARS or similar phenotypes affecting five different genes/regions. USP9X and JAG1 explained three families each. USP9X was recently linked with syndromic cognitive impairment that includes hearing loss, dental defects, ventriculomegaly, Dandy-Walker malformation, skeletal anomalies (hip dysplasia), and other features showing a significant overlap with FOXC1 -ARS...

Developmental dysplasia of the hip (DDH), if uncorrected, can result in several chronic abnormalities, including chronic hip pain, degenerative arthritis, and gait abnormalities. The outcome of DDH generally depends on the age of presentation; a worse prognosis is linked to a higher age of presentation. Although treatment continues to be a challenge, recent advancements in the field have improved our understanding of the disease, which has resulted in advancements in DDH surveillance during infancy and the reduction of complications with early intervention...
