Abstract
Residual hip dysplasia may exist despite appropriate treatment of congenital hip dysplasia (CHD). The abnormalities chiefly affect the acetabulum and can lead to premature osteoarthritis. Although the main cause is delayed treatment of CHD, primary lesions are also possible and may be worsened by the initial treatment itself. Residual hip dysplasia must be detected during the follow-up of patients with CHD. The antero-posterior radiograph of the pelvis is the main diagnostic tool. However, the importance of non-ossified anatomical structures requires additional investigations such as arthrography and magnetic resonance imaging. The risk of premature osteoarthritis is difficult to predict based only on the imaging-study findings. Hip dysplasia is best treated before 5 years of age. The work-up at this age should allow determination of the best treatment. Surgery is required but should not be performed unnecessarily. The decision rests on the absence of improvement in the radiographic criteria and on the findings from additional imaging studies. The usual treatment is Salter's osteotomy, during which excessive anterior displacement should be avoided. At adolescence, the information provided by radiography in the coronal plane should be completed by a three-dimensional evaluation of the acetabulum and an assessment of the quality of the labrum. The shelf procedure has been proven to relieve pain and to significantly postpone the need for hip arthroplasty, when performed early, before the development of visible osteoarthritis, and on a congruent hip. Chiari's osteotomy has a role to play in complex dysplasia affecting both the acetabulum and the femur. Periacetabular osteotomy is getting more used thanks to cooperation between paediatric and adult orthopaedic surgeons. This osteotomy provides optimal correction in all three dimensions.

Abstract
The aim of this study was to perform periacetabular triple osteotomy (PATO) in children under 6-years-old with severe acetabular deficiency aiming to obtain important correction and avoid excessive pressure on epiphysis, anterior overcorrection and acetabular retroversion. This is a retrospective study of 29 PATO using single anterior approach in 24 patients under 6-years-old with dysplasia of the hip. Clinical examination and radiographic evaluation were done pre-op, post-op and at last follow-up. Computed tomography (CT) scan was obtained, comparing operated hip to contro-lateral normal hip. Clinical examination of the operated hip, at the last follow-up, showed a normal range of motion with nonsignificant difference when compared to normal hip. All hips were classified as Wicart A, and all activities were allowed. Radiographically, X-ray revealed improvement of all parameters postoperatively, with nonsignificant change compared to the last follow-up. CT-2D axial analysis demonstrated the absence of acetabular retroversion with good anterior and posterior coverage. CT-3D imaging comparing the anterior acetabular inclination, anterolateral and posterolateral inclination angles of operated hip and normal hip showed comparable results. Patients less than 6 years with severe acetabular deficiency could benefit from PATO. Performing osteotomies close to joint gave important acetabular fragment freedom, allowing an important correction. Appropriate manoeuver of reorientation avoided anterior overcorrection and acetabular retroversion, responsible for early pain and osteoarthritis. Age should not be the only criteria to choose the type of osteotomy. Level of evidence: level IV.

Abstract
INTRODUCTION Early diagnosis and early treatment have become the gold standard for management of developmental dysplasia of the hip. Surgery is required in case of failed initial treatment. Innominate pelvic osteotomy of Salter (SIO), Pemberton's pericapsular osteotomy (PPO) and Dega's acetabuloplasty (DA) are among the most used procedures.We performed a systematic review and meta-analysis of the past 57 years in order to assess the mid- and long-term outcome of these techniques. METHODS Studies met inclusion criteria if they: (1) reported at least 5 cases treated by 1 of the abovementioned surgical techniques; (2) included children aged between 1 and 8 years; (3) surgical indication was late detected DDH or a failed initial treatment; (4) presented a minimal follow-up of 24 months; (5) reported the radiological score of Severin and/or the clinical score of McKay.Clinical and radiological outcomes were dichotomised into favourable and unfavourable outcome and weighted summary rates were determined using meta-analysis models. RESULTS From a total of 7391 articles, 48 level of evidence grade IV articles were included in our review. A total of 2143 cases with a mean follow up of 112.4 months were included.Pooled Severin score indicated a statistically better outcome for PPO and DA compared to SIO (p = 0.0003 and p = 0.002, respectively). By dichotomising the results in favourable and unfavourable outcome, PPO showed the best results (p = 0.0002 vs. SIO, p = 0.01 vs. DA).Pooled McKay score showed a statistically better outcome for PPO and DA compared to SIO (p < 0.0001 and p = 0.03, respectively) as well as better outcomes for PPO compared to DA (p = 0.01). By dichotomising the results in favourable and unfavourable, PPO showed the best results. CONCLUSIONS Even if our review demonstrates slightly better radiological and clinical results with the PPO, the currently available and limited data do not allow for clear recommendation towards one of these techniques.

Abstract
BackgroundWe aim to describe a modified Dega osteotomy technique in detail, emphasizing its eventual advantages in comparison to the original Dega osteotomy and ‘San Diego’ modification. We also present our related literature review on various osteotomy techniques.MethodsWe reviewed the radiological indices of 27 dysplastic hips in 25 children with cerebral palsy and developmental dislocation of the hips (9 boys, 16 girls; mean age, 5 years) who underwent a modified Dega osteotomy according to Paley.ResultsComparing the radiological indices results between our patients and those reported by the various authors in the literature, the data are almost identical.ConclusionsThe modified Dega osteotomy is the only technique wherein all two limbs of the triradiate cartilage are true, which becomes a single hinge where the osteotomy turns. Despite the similar results in the radiological indices between our patients and those in the literature, we still consider that the entire triradiate cartilage is a better hinge point for the iliac osteotomy. The difference between the osteotomy adopted in our institution and the modality described by most authors in the literature is that the latter mostly ignore or miss the ischial limb of the triradiate cartilage.

Abstract
Pelvic osteotomies are used for hip preservation in children and young adults to improve femoral head coverage and stabilize the hip joint. Redirectional osteotomies aim to reduce the overall volume and redirect the acetabulum. These include Salter, Pemberton, Dega, and San Diego osteotomies. Reorientation osteotomies aim to reorient the acetabulum and include periacetabular and triple osteotomies. Salvage osteotomies aim to enlarge the acetabulum and medialize the hip center. These include shelf and Chiari osteotomies. The standard anterior approach and surgical technique for the eight pelvic osteotomies used by hip preservation surgeons are described along with each osteotomy's history, indications, and outcomes.

Abstract
BACKGROUND Acetabular remodeling may not be predictable after open reduction in developmental dysplasia of the hip (DDH) in older children. Several acetabuloplasties have been developed, and all are aimed at correcting the dysplastic acetabulum. The goal of this study is to evaluate if the type of pelvic acetabuloplasty and the corrected (postoperative) acetabular index (AI) affect early follow-up femoral head coverage. METHODS A retrospective review of single-surgeon consecutive acetabuloplasties (Dega or Pemberton) from December 2012 to December 2015 was conducted. The inclusion criteria were a diagnosis of DDH, undergoing simultaneous primary open reduction, and follow-up of at least 18 months. Univariable analysis was based on the type of acetabuloplasty. The correlation between AI and final center edge angle (CEA) was tested. Multiple regression was performed. RESULTS Of the total 58 hips in 39 patients included, 41 underwent Dega acetabuloplasty, and 17 had Pemberton acetabuloplasty. The median follow-up was 40.50 months (interquartile range 27.25-57). Pemberton acetabuloplasty produced a lower corrected AI, but the difference was not significant in follow-up measurements. Corrected AI was significantly correlated with final CEA (R = - 0.31, P = 0.018). In the multiple regression, only corrected AI was independently associated with final CEA (B = - 0.29, SE = 0.15, P = 0.06), whereas the type of acetabuloplasty, age, and preoperative severity of the dislocation were not. CONCLUSION The correction obtained during acetabuloplasty affects early follow-up femoral head coverage. Ensuring proper sizing and placement of the grafted bone is probably more important than the type of acetabuloplasty chosen. LEVEL OF EVIDENCE Level III.

Anterior and lateral overcoverage after triple pelvic osteotomy in childhood for developmental dislocation of the hip with acetabular dysplasia: Frequency, features, and medium-term clinical impact. Orthop Traumatol Surg Res 2018; 104:383-387. [PMID: 29474949 DOI: 10.1016/j.otsr.2017.12.020] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2017] [Revised: 12/13/2017] [Accepted: 12/19/2017] [Indexed: 02/02/2023]
Abstract
BACKGROUND Triple pelvic osteotomy (TPO) is a treatment option in children and adolescents with residual acetabular dysplasia after developmental dislocation of the hip (DDH). However, TPO to redirect the acetabulum is often blamed for anterior and lateral overcoverage of the femoral head. The main objectives of this study were to assess the potential clinical impact, frequency, and radiological features of acetabular overcorrection. Evidence of post-operative remodelling and associations linking younger age at surgery and/or dysplasia severity to the existence and magnitude of overcorrection were sought. HYPOTHESIS Acetabular overcorrection has little or no clinical impact. PATIENTS AND METHODS TPO was performed on 41 hips in 31 patients at a mean age of 6.3 years (range, 3.0-15.2 years). Mean follow-up was 13.8 years (range, 5.4-28.7 years) and mean age at last re-evaluation was 22.1 years (range, 13-39 years). Clinical outcomes were assessed based on the Harris Hip Score (HHS) and Postel-Merle d'Aubigné (PMA) score. Radiographs were used to look for a cross-over sign (CO+) and to measure the vertical-centre edge (VCE) and vertical-centre anterior (VCA) angles and the acetabular index (AI). Overcorrection was defined as AI≤0° and/or VCE≥35° and/or VCA≥40° and/or CO+. RESULTS The HHS and PMA score values were good or excellent for 39 (94%) hips. One or more parameters indicated overcorrection of 33 (80.5%) hips. No significant differences were found between the overcorrected hips and the hips with normal parameters. DISCUSSION TPO effectively corrects residual acetabular dysplasia. Overcorrection is common in all three planes but has little clinical impact in young adults. The high frequency of overcorrection mandates a careful pre- and intra-operative evaluation of acetabular version. LEVEL OF EVIDENCE IV, retrospective study.

Abstract
BACKGROUND Most orthopedic surgeons prefer spica cast immobilization in children for 4 to 12 weeks after surgical hip reconstruction in children with developmental hip dysplasia. This challenging treatment may be associated with complications. Studies are lacking that focus on early mobilization without casting for postoperative care after hip reconstruction. METHODS Twenty-seven children (3.4±2.0 years), including 33 hips with developmental hip dysplasia (DDH) and dislocation of the hip (Tönnis grade 1 to 4), who underwent hip reconstruction (Dega acetabuloplasty, varisation-derotation osteotomy and facultative open reduction) were retrospectively included in this study. Postoperatively the patients were placed in an individual foam shell with 30 degrees of hip abduction, hip extension, and neutral rotation. Early mobilization physiotherapy was performed within the first few days after the surgery under epidural anaesthesia. Full weight bearing was allowed after 3-4 weeks. All children received a clinical examination and radiographic evaluation before and after surgical intervention. The follow-up period was 12.3±2.9 months. RESULTS On average, the postoperative acetabular index decreased significantly from 36.9 to 21.7 degrees and the center-edge angle increased from 9.9 to 28.6 degrees. All hips had reached Tönnis grade 1 at the time of the last follow-up. No complications such as dislocation of the bone wedge, avascular necrosis of the acetabulum or femur, lack of non-union, or nerve injury, were reported. CONCLUSIONS In this cohort study, hip reconstruction was successful according to clinical and radiographic outcome parameters after early mobilization without cast therapy. Early mobilization may be used as an alternative treatment option after hip reconstruction in DDH.

Abstract
BACKGROUND The purposes of this study were to evaluate acetabular remodeling after closed reduction of developmental dysplasia of the hip (DDH) and to delineate the role of osteotomy. METHODS Eighty-four hips with DDH treated with closed reduction and followed until the patient was 8 years of age or older were included in this study. The mean age at closed reduction was 14.0 months (range, 3 to 30 months) and that at the latest follow-up visit was 12.7 years (range, 8.0 to 24.7 years). Osteotomy was performed in 26 hips (31%) during the follow-up period, at an average age of 2.8 years (range, 2.0 to 5.8 years). The acetabular index (AI) and center-edge angle (CEA) were measured, and osteonecrosis was graded. The treatment outcome was evaluated as satisfactory (Severin grade I or II) or unsatisfactory (III or IV). We retrospectively analyzed the associations among radiographic parameters, performance of osteotomy, grade of osteonecrosis, and final outcome. RESULTS A satisfactory outcome was observed in 67 (80%) of the 84 hips. An osteotomy was not performed in 30 of 34 hips with an AI of <32° and a CEA of >14° at the age of 3 years, and 28 (93%) of these 30 hips showed a satisfactory outcome. Of the 33 hips with an AI of ≥32° and a CEA of ≤14° at the age of 3 years, the 20 that had undergone an osteotomy showed a higher proportion of satisfactory outcomes than the 13 hips that had not (p = 0.01). Three of the 4 hips that showed an unsatisfactory outcome following an osteotomy had an AI of ≥34° at 1 year post-osteotomy. Grade-II, III, or IV osteonecrosis, according to the Bucholz-Ogden classification, developed in 10 of the 84 hips, and these 10 hips had a higher proportion of unsatisfactory outcomes than did those that developed no or grade-I osteonecrosis (p = 0.004). CONCLUSIONS Hips with DDH showing poor acetabular remodeling after closed reduction may benefit from osteotomy. The AI and CEA at the age of 3 years can serve as one of the guidelines for osteotomy. Continued surveillance for acetabular remodeling is required even after osteotomy. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
