“…In our series, only 8.2% of all hips presented with a positive Trendelenburg sign and 8.7% of patients presented with a limp. The result of Trendelenburg sign was superior to the cases described by Chen et al [20] (14.2%) and Fukui et al [10] (13%). Furthermore, a recent gait analysis study by Karaismailoglu et al [26] claimed that the bilateral HHC technique could provide similar gait characteristics as anatomical reconstruction.…”

“…Because the posterosuperior bone above the native acetabulum is almost intact, the acetabular cup can be placed at high hip center to optimize host bone-implant contact [20]. In this study, we aimed to assess the utility of HHC technique used in patients with Crowe II-III DDH and evaluated the clinical and radiographic results between different heights of hip center.…”

Background: High hip center technique is still controversial about the survivorship of prothesis and postoperative complications. We aimed to show the utility of high hip center technique used in patients with Crowe II-III developmental dysplasia of the hip at the midterm follow-up and evaluated the clinical and radiographic results between different heights of hip center.Methods: We retrospectively evaluated 69 patients (85 hips) with Crowe II-III dysplasia who underwent a high hip center cementless total hip arthroplasty at a mean follow up of 8.9 years (range, 6.0-14.1years). The patients were divided into two groups according to the height of hip center, respectively group A (≥22mm and <28mm) and group B (≥28mm). Radiographic, functional and survivorship outcomes were evaluated.Results: The mean location of the hip center from the inter-teardrop was 25.1mm vertically and 30.0mm horizontally in the group A, and 33.1mm vertically and 31.4mm horizontally in the group B. There were no statistically significant differences between two groups in postoperative femoral offset, abductor lever arm, leg length discrepancy and cup inclination. At the final follow up, the mean WOMAC and Harris hip score were significantly improved in both groups. Of the 85 hips, 7 hips (8.2%) showed a positive Trendelenburg sign. Additionally, 6 patients (8.7%) presented with a limp. No significant differences were shown regarding the Harris hip score, WOMAC score, Trendelenburg sign and limp between two groups. The Kaplan-Meier implants survivorship rates at the final follow-up for all-causes revisions in the group A and group B were similar (96.7% [95% confidence interval, 90.5%-100%] and 96.2% [95% confidence interval, 89.0%-100%], respectively).Conclusions: The high hip center technique is a valuable alternative to achieve excellent midterm results for Crowe II-III developmental dysplasia of the hip. Further, we reported good results and could not demonstrate any significant differences in outcomes or survivorship between the groups with differing degrees of HHC in our study, however the relatively small sample size must be considered and larger comparative studies are required to confirm the value of high hip center technique.

“…In some cases, the new acetabulum can be formed in a higher position than the true acetabulum because of the acetabular bone deficiency (Figure 2). There are several studies that showed good results with cemented and noncemented acetabular components [21,50,51]. Results of a study that was compared the survivorship of the components for anatomical or high-cup placement; 100% in the anatomical placement and 97% for high hip center group [52].…”

Introduction: Surgical treatment methods for developmental dysplasia of the hip (DDH) in the elderly patients contain pelvic or periacetabular osteotomy and hip arthroplasty. Total hip arthroplasty (THA) is the last and definitive surgical treatment modality for the end stage developmental dysplasia of the hip. Deformity classification and reconstruction:Crowe classification system describes the degree of dysplasia and gives information about the reconstruction procedure with hip arthroplasty. Classification is based on the magnitude of proximal femoral migration relative to the acetabulum. Acetabular component must be implanted to the true acetabulum for the optimal range of motion and stability of the reconstructed hip. The femoral component must be placed in neutral or slight anteversion but narrow femoral canal can be a problem for the reconstruction of femur. Conclusion-key results:The results of total hip arthroplasty in developmental dysplasia of the hip have been satisfactory for stability, mobility, and pain relief. The survivorship of cemented arthroplasty in dysplastic hips is inferior because of the young age of the patients and the complexity of the procedures. Early and midterm results of cementless hip arthroplasty are better. Most important complications after the surgery are dislocation of the reconstructed hip and sciatic nerve injury.

“…Nevertheless, Chen et al (33) mention that the concept of high hip centre (HHC) may insufficiently illuminate the degree of elevating rotation center of the hip owing to individual differences. They introduced the concept of ratio of the HHC to the height of patient.…”

The necessity to restore the anatomic hip centre in congenital hip disease

et al. 2016

View full text Add to dashboard Cite

Total hip replacement (THR) is the treatment of choice for the patient suffering from end-stage hip osteoarthritis. In the presence of deformities due to congenital hip disease (CHD), THR is, in most of the cases, a difficult task, since the technique of performing such an operation is demanding and the results could vary. We present our experience and preferred strategies focusing on challenges and surgical techniques associated with reconstructing the dysplastic hip.
