4. High Hip Center Reduces the Dynamic Hip Range of Motion and Increases the Hip Load: A Gait Analysis Study in Hip Arthroplasty Patients With Unilateral Developmental Dysplasia. (PubMed)

High Hip Center Reduces the Dynamic Hip Range of Motion and Increases the Hip Load: A Gait Analysis Study in Hip Arthroplasty Patients With Unilateral Developmental Dysplasia. Long-term favorable clinical outcomes of anatomical or high hip center techniques in total hip arthroplasty (THA) are reported in patients with developmental dysplasia of the hip (DDH). However, there is little information about the effect of the hip center location on gait characteristics. The purpose of this study (...) was to compare these surgical techniques with gait analysis, analyze the effect of the hip rotation center location on gait parameters, and discuss the possible problems that may arise.A total of 40 patients who underwent THA due to unilateral coxarthrosis secondary to Crowe type III-IV DDH and completed 5 years of follow-up were included in the study. Group 1 included 20 patients who underwent anatomical hip center reconstruction, while group 2 included 20 patients who underwent high hip center

5. Retrospective observational study comparing the international hip dysplasia institute classification with the Tonnis classification of developmental dysplasia of the hip. (PubMed)

Retrospective observational study comparing the international hip dysplasia institute classification with the Tonnis classification of developmental dysplasia of the hip. The Tonnis radiographic classification of developmental dysplasia of the hip (DDH) has been widely used. The International Hip Dysplasia Institute (IHDI) classification, a new classification system recently developed by the IHDI, is beginning to be applied to evaluate DDH with the absence of an ossification center. This study (...) aimed to validate its reliability in evaluating DDH with an ossification center and compared the 2 classifications in evaluating all DDH hips. In addition, the prediction values of the 2 classifications on clinical management selection were compared.In total, the pelvic radiographs of 212 DDH patients (318 hips) between the ages of 6 and 48 months admitted to Shanghai Children's Medical Center between 2007 and 2014 were assessed by 3 observers retrospectively using the 2 classifications

7. Evaluating the role of prereduction hip traction in the management of infants and children with developmental dysplasia of the hip (DDH): protocol for a systematic review and planned meta-analysis. (PubMed)

Evaluating the role of prereduction hip traction in the management of infants and children with developmental dysplasia of the hip (DDH): protocol for a systematic review and planned meta-analysis. Developmental dysplasia of the hip (DDH) affects 4-6 per 1000 live births in developed countries. Effective treatment to realign the hip is necessary to avoid long-term morbidities and maximise functional outcome. Treatment options depend on patient age but typically involve hip bracing (...) and/or reduction under general anaesthetic. Some centres also employ prereduction hip traction. Historical papers suggest traction reduces risk of avascular necrosis (AVN) femoral head and reduces requirement for open reduction. However, several studies including a large retrospective cohort study, dispute this. We propose to perform the first systematic review and meta-analysis to clarify the value of prereduction hip traction in the management of DDH in children under the age of 3 years by identifying

8. Three-Dimensional Host Bone Coverage Required in Total Hip Arthroplasty for Developmental Dysplasia of the Hip and Its Relationship With 2-Dimensional Coverage. (PubMed)

Three-Dimensional Host Bone Coverage Required in Total Hip Arthroplasty for Developmental Dysplasia of the Hip and Its Relationship With 2-Dimensional Coverage. In total hip arthroplasty, the minimum host bone coverage required on the cup for stable fixation has been previously reported; however, the coverage was generally evaluated on a 2-dimensional (2D) image and 3-dimensional (3D) coverage has not been well described.We used postoperative computed tomography images to retrospectively (...) measure 3D cup coverage in 151 hips with developmental dysplasia of the hip that underwent primary total hip arthroplasty. The aims were to (1) determine the minimum requirement of the 3D coverage for stable cup fixation; (2) evaluate the relationship between 2D and 3D coverage; and (3) identify the factors associated with 2D-3D discrepancy, defined as follows: 2D-3D discrepancy = 2D coverage-3D coverage.All cups showed stable fixation as demonstrated by bone ingrowth with an average postoperative

9. Developmental Dysplasia Treated With Cementless Total Hip Arthroplasty Utilizing High Hip Center Reconstruction: A Minimum 13-Year Follow-up Study. (PubMed)

Developmental Dysplasia Treated With Cementless Total Hip Arthroplasty Utilizing High Hip Center Reconstruction: A Minimum 13-Year Follow-up Study. The primary aim of this study was to determine the clinical outcomes at 13-year follow-up of patients diagnosed with developmental dysplasia of the hip and subsequently treated with total hip arthroplasty (THA). The secondary aim was to investigate the effect of hip center location on clinical outcomes and polyethylene wear.We reviewed data from (...) . The nondysplastic and Crowe I group showed no longitudinal change in HHS (P = .243).This cup design and highly cross-linked polyethylene liner combination demonstrates excellent clinical outcomes, similar to THA for primary osteoarthritis, through 13-year follow-up in patients with various degrees of developmental dysplasia of the hip and HHC reconstructions.Copyright © 2018 Elsevier Inc.

10. Total Hip Arthroplasty for Crowe Type IV Developmental Dysplasia of the Hip Using a Titanium Mesh Cup and Subtrochanteric Femoral Osteotomy (PubMed)

Total Hip Arthroplasty for Crowe Type IV Developmental Dysplasia of the Hip Using a Titanium Mesh Cup and Subtrochanteric Femoral Osteotomy Treatment of Crowe IV developmental dysplasia of the hip (DDH) with total hip arthroplasty (THA) reconstructs the true acetabulum, which improves hip biomechanics and function. However, restoration of the native acetabulum may lead to limb lengthening and traction neuropraxia. The purpose of this study is to describe the short term results (...) of a retrospectively reviewed series of patients with Crowe IV DDH treated with THA using a titanium mesh cup, cemented liner, and subtrochanteric femoral shortening osteotomy.Eighteen patients (21 hips) with an average age of 47 years (age range: 28-61 years) with Crowe IV DDH underwent reconstructive THA and subtrochanteric femoral shortening osteotomy between September 2005 and February 2014.

A simple technique to strengthen the initial and mid-term to long-term stability of the cup during total hip arthroplasty in developmental dysplasia of the hip To assess the effects of a technique of cup blocking screws combined with impaction bone grafting during total hip arthroplasty (THA) for patients with developmental dysplasia of the hip (DDH).From August 2011 to July 2015, 53 patients (59 hips) with DDH in our hospital were treated with THA using the technique of cup blocking screws (...) combined with impaction particulate bone grafting. These patients were prospectively followed, and the clinical and imaging results were collected.Harris hip score (HHS) was raised from 41.24 before surgery to 91.49 at the latest follow-up (p less than 0.001). Length discrepancy (LLD) was reduced from 28.97 mm before surgery to 6.08 mm after surgery (p less than 0.001). No loosening of the cup was detected at the last follow-up. The differences were insignificant in cup inclination and rate of cup

Gender and Disease Severity Determine Proximal Femoral Morphology in Developmental Dysplasia of the Hip. In this computed tomography (CT) morphological study we describe the way the proximal femoral morphology differs with worsening degrees of developmental dysplasia of the hip (DDH) and describe gender differences in patients with DDH. 49 male patients with DDH were matched with 49 females with DDH, using age and the Crowe classification of DDH severity. The femoral length, anteversion, neck (...) -shaft angle, offset, neck length, canal-calcar ratio, canal flare index, lateral center-edge angle, alpha angle, pelvic tilt and pelvic incidence were measured for each patient on their pre-operative CT scans, prior to total hip arthroplasty surgery. Femoral anteversion and neck length were 16° and 47 mm, 25°and 36 mm, 26° and 43 mm, and 44° and 36 mm, for Crowe I and III males and Crowe I and III females, respectively.
