Eight-year follow-up of uncemented hydroxyapatite coated hip prosthesis for hip osteoarthritis secondary to developmental hip dysplasia

Long-term follow-up studies on children with surgically treated developmental dysplasia of the hip (DDH) have shown that not only the affected side progresses to premature osteoarthritis, but the unaffected side may also suffer from insidious hip dysplasia or osteonecrosis. The current gait analysis study identified the loading and unloading rates of the ground reaction forces (GRF) and lower limb joint axial forces during gait, and their correlations with the hip morphology in twenty juvenile patients with surgically treated unilateral DDH during toddlerhood. In a gait laboratory, each subject walked at preferred speed on a 10-m walkway while the kinematics and the GRF were measured. Loading and unloading rates of the vertical GRF and the joint axial forces were obtained as the maximum instantaneous slope of these force curves. Radiographic measurements of the hips were taken, and the correlations between the morphological parameters and the loading and unloading rates were obtained. The patients showed greater-than-normal peak loading rates of the joint axial forces, and the loading rates on both the affected and unaffected sides were strongly correlated to the acetabular index on the unaffected side, which was also significantly correlated with the peak unloading rates on the affected side. These results suggest that apart from regular follow-up of the affected hip, routine assessment of the morphological changes and/or increased loading rates on the unaffected hip is also important for early identification of any signs of insidious hip dysplasia and risk of premature degeneration of the cartilage.

Introduction The possibility of gradual closed reduction of hip dislocation in children over 1.5 years old is considered doubtful. Purpose Analysis of long-term results of applying the Ilizarov technique of gradual closed reduction in combination with the reconstruction of the hip joint components. Methods The outcomes of treatment of 62 children (81 joints) with congenital hip dislocation in the follow-up period from 5 to 16 years were studied. The treatment method included closed reduction of the dislocation using the technology proposed by G.A. Ilizarov and subsequent reconstruction of the joint components. The patients are divided into two groups based on their age. The first group included 33 patients (43 joints) under the age of 5 years. The second group consisted of 29 patients (38 joints) aged 5–8 years. Results Closed reduction failed in five cases. The recurrence of dislocation after closed reduction was 5.3 %. The rate of aseptic necrosis after closed reduction was 9.7 %. Good functional outcomes were reported in 87.7 %. They were significantly better in the younger group. The proportion of good anatomical results did not depend on age and was 77 % in general. Poor results were obtained in 8.8 %. Conclusion The anatomical and functional outcomes and the number of complications by using the technique described were comparable to other methods of gradual closed reduction of hip dislocation. But the technique we have described expands the age restrictions for its use.

Abstract Long-term follow-up studies on children with surgically treated developmental dysplasia of the hip (DDH) have shown that not only the affected side progresses to premature osteoarthritis, but the unaffected side may also suffer from insidious hip dysplasia or osteonecrosis. The current gait analysis study identified the loading and unloading rates of the ground reaction forces (GRF) and lower limb joint axial forces during gait, and their correlations with the hip morphology in twenty juvenile patients with surgically treated unilateral DDH during toddlerhood. Radiographic measurements of the hips were taken, and the correlations between the morphological parameters and the loading and unloading rates were obtained. The patients showed greater-than-normal peak loading rates of the joint axial forces, and the loading rates on both the affected and unaffected sides were highly correlated to the acetabular index on the unaffected side, which was also significantly correlated with the peak unloading rates on the affected side. These results suggest that apart from regular follow-up of the affected hip, routine assessment of the morphological changes and/or increased loading rates of the unaffected hip is also important for early identification of any signs of insidious hip dysplasia and risk of premature degeneration of the cartilage.

The Mean

Purpose: To evaluate the acetabular cup and graft survival in patients who underwent total hip arthroplasty (THA) with the diagnosis of dysplastic hip osteoarthritis and received a femoral head autograft due to acetabular coverage deficiency. Methods: Between January 2005 and December 2016, 83 hip prostheses of 80 patients who underwent THA using femoral head autografts and were followed up for at least 2 years were retrospectively evaluated. Seventy-four hips of the remaining 71 patients (57 female (80%)) were included. Mean patient age at surgery was 51 ± 16 (range 18–76) years. The mean follow-up duration was 76 ± 25 (range 25–161) months. Acetabular inclination and graft thickness, contact length, percentage of coverage, and graft resorption were examined on postoperative and final follow-up radiographs. The presence of a radiolucent area around the acetabular and femoral components indicating loosening was also evaluated. Results: The mean postoperative acetabular component inclination was 44 ± 5.1° (range 30–48°) with mean graft coverage of 34 ± 4.8% (range 24–46%). In all patients, autograft union with the pelvis was seen and the lateral overflow was remodeled. Fifteen patients (20%) underwent revision surgery due to aseptic acetabular component loosening in four, nontraumatic recurrent dislocations in eight, periprosthetic infection in one, acetabular component protrusion in one, and traumatic hip dislocation in one. Conclusion: In patients with osteoarthritis secondary to developmental hip dysplasia, the use of femoral head autografts to eliminate acetabular coverage deficiency during THA achieves acceptable midterm postoperative radiological outcomes. Increased acetabular bone stock may be beneficial in possible future revision surgeries.
