“…Patient factors (history of neurological disease and weakness of abduction muscles), morphological factors (center-edge angle, femoral neck offset, and leg length discrepancy), and surgical factors (surgery approach, choice of prosthesis, and repair of the short external rotator tendons) were reported to play an important role in dislocation after bipolar hemiarthroplasty [9–12]. Adanir et al reported measurements such as the center-edge angle and acetabular depth (which evaluated the shallowness of the acetabulum) were used to assess acetabular dysplasia [13], but the relationship between these measurements and dislocation after bipolar hemiarthroplasty for patients without acetabular dysplasia remained unclear. In the current study, we explored the morphological risk factors for dislocation after bipolar hemiarthroplasty.…”

BackgroundThe relationship between preoperative hip measurements and dislocation after bipolar hemiarthroplasty is presently unclear. In the current study, we investigated the morphological risk factors associated with dislocation after bipolar hemiarthroplasty of the hip in patients with femoral neck fractures.MethodsBetween January 2011 and June 2017, a nested case-control design study was used to analyze the risk factors for dislocation in 348 patients who had undergone bipolar hemiarthroplasty because of femoral neck fractures. Twelve patients underwent at least one dislocation postoperatively. Sixty patients without dislocation were selected as controls matched in terms of time of surgery, age, and sex, at a ratio of 1:5. Patient acetabular measurements were compared between the dislocation group and the control group, including the center-edge angle, abduction angle, acetabular width and depth, depth-to-width ratio, femoral neck offset, leg length discrepancy, and femoral head coverage ratio. A multivariate logistic regression model was used to evaluate the morphological risk factors of dislocation.ResultsPostoperatively, the incidence of dislocation was 3.4%. A smaller center-edge angle was found to be a risk factor associated with dislocation after bipolar hemiarthroplasty of the hip. Patients with small acetabular depth and a small acetabular depth–width ratio were prone to dislocation. Patients with a center-edge angle of ≤ 45.4° or an acetabular depth of ≤ 19.12 mm were more likely to suffer dislocation.ConclusionsCareful preoperative measurements before bipolar hemiarthroplasty of the hip are important. Surgical intervention for femoral neck fracture patients with a shallow acetabulum should be carefully planned and total hip arthroplasty should be considered when necessary.

“…This causes a high rate of adults suffering from early coxarthrosis (4). For example, in a Turkish population of more than 200 patients over 80% of cases of hip osteoarthritis were linked to hip dysplasia (5). In adults hip dysplasia is usually classified by Hartofilakidis(6) depending on the grade of dislocation of the femoral head.…”

Hip dysplasia is a congenital defect of the hip joint in infants with mismatch of the femoral head and the acetabulum. It can be treated in infants via conservative or surgical containment of the femoral head. In developing countries cases of hip dysplasia are often overlooked and neglected. Therefore, many cases of severe coxarthrosis with dislocations of the femoral head can be observed. The dislocation complicates the implantation of a hip prosthesis. This article shows a novel technique in total hip replacement in a case report.

“…Developmental dysplasia of the hip (DDH) is a disease characterized by hip dislocation or subluxation and acetabular morphological abnormalities observed in infants and children 5 . The incidence of DDH is racially different and is reportedly high in Japanese 6 , Singaporean 5 , Native American 7 , and Turkish populations 8 , and in Sami populations in Scandinavia 9 . In the Japanese population prior to 1965, dislocation was present in approximately 1.1% to 3.5% of all newborns 6 , and severe subluxation was present among adults 10 (Fig.…”

Background: The incidence of developmental dysplasia of the hip (DDH) in Japanese newborns has reduced drastically following a primary prevention campaign initiated around 1972 to 1973; this perinatal education campaign promoted maintaining the hips of newborns in the naturally flexed-leg position. The purpose of the present study was to describe the life course epidemiology of hip osteoarthritis (OA) in adolescent and adult patients and to assess its association with exposure to the primary prevention campaign for DDH. Methods: We included new patients with hip OA diagnosed from January 1, 2022, to December 31, 2022, at 12 core hospitals (8 special-function hospitals and 4 regional medical care support hospitals). The trend in the percentage of hips with a history of DDH treatment in childhood was estimated with use of a centered moving average using the birth year of the patient. We compared the prevalence of severe subluxation (Crowe type II, III, or IV) between patients with secondary hip OA due to hip dysplasia who were born in or before 1972 and those who were born in or after 1973. Results: Overall, 1,095 patients (1,381 hips) were included. The mean age at the time of the survey was 63.5 years (range, 15 to 95 years). A total of 795 patients (1,019 hips; 73.8% of hips) were diagnosed with secondary OA due to hip dysplasia. Approximately 13% to 15% of hips among patients born from 1963 to 1972 had a history of DDH treatment in childhood; however, the percentage decreased among patients born in or after 1973. The prevalence of severe subluxation (Crowe type II, III, or IV) among patients born in or after 1973 was 2.4%, which was significantly less than that among patients born in or before 1972 (11.1%; odds ratio, 0.20; p < 0.001). Conclusions: As of 2022, secondary hip OA due to hip dysplasia is still responsible for most new cases of adolescent and adult hip OA seen in core hospitals in Japan. However, the perinatal education campaign initiated 50 years ago, which utilized a population approach and advocated for maintaining the hips of newborns in the naturally flexed-leg position, may have improved the environmental factors of DDH, as indicated by the apparently reduced need for treatment of DDH in childhood and the associated severe subluxation. This may result in a reduced need for challenging hip surgery later in life. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
